basic structure of novelty yarn

Varying widths and colors, laddering, twists and curls define this category of wonderfully unique yarns. TEXTILE SPINNING Textile Technology knowledge series Volume II TEXCOMS TEXTILE SOLUTIONS APRIL 21, 2019 In a slash yarn, the enlarged area is longer and thinner than in a nub yarn. In this method, it is recommended that raw materials with shrinkage properties (such as PAN or filament man-made fiber) are used in order to obtain the desired effect. Basic/Simple Weaves; Compound/Complex/Novelty … Fancy yarns can be created by deliberately introducing irregularities or intermittent effects along their length. There can be endless variety of novelty yarns. C. reed. Yet, I don't often know what to do with them. Ply yarn: Definition. Shetland yarn: The 2-ply yarn used for sweaters. Nub and slash yarns have the effect strand twisted around the core strand a number of times in a small area to form an enlarged bump or ‘nub’. chenille yarn, loop yarn, slub yarn, snarl yarn. The most common novelty yarn material is wool. Corkscrew, spiral, chenille, gimp, loop, snarl and boucle have all found acceptance in apparels and for the production of furnishings and upholstery. A deliberate difference in length, denier, cross-section and modulus of component fibres can be exploited to position them at predetermined zones of the yarn cross-section, with short and coarse fibres occupying the yarn surface. The chenille threads are usually imported from Italy. Ply Yarns are Ratine, Spiral, Knot, Snarl and Boucle. Well you're in luck, because here they come. Typically, slubs are randomly and irregularly spaced along the yarn axis. Similarly to the ring system, the production of a fancy yarn with a hollow spindle requires three different components: core, effect and binder. Slubs of varying dimensions can be produced by using differential fibre length in the core and effect components. Manufactured By a solution in forced through very … Capital investment for starting a new knitting unit is less than that required for other fabric-producing industries. Sports yarn: The 3-ply yarn used for socks, sweaters, and hats. The basic structure of a gimp yarn is illustrated in Figure-6 . Knitting is more flexible than weaving, i.e. The most popular color? (of yarn) having irregularities within the fibrous structure. Modern knitting machines, particularly warp knitting machines can produce various types of technical textiles (medical textiles, automobile textiles, geo-textiles, etc.). The differences in the appearance of the various yarns are largely dependent on the extent of prominence of the effect strand. Moreover, the requirement to match the twist of base thread is reached at the weft knit fabric manufacturing stage. The core thread forms the base of the structure onto which the effect thread produces the geometrical shape or profile of the effect, which can be loops, knops, snarls, etc. The term fancy, complex and novelty are considered synonymous. Novelty Yarn comes in a variety of colors and textures and add interest to a knitted garment. Fancy yarns are made with a distinctive irregular profile which is different from basic single and folded yarns. E. batten. It is composed of two 1/1 ribs interlocked together with crossed sinker wales (Figure 1 a). 9.6c typically has a fine strand spiraling around a soft and bulky strand. Fancy yarns are generally produced by the irregular plying of staple fibre or continuous filaments and are characterised by the presence of abrupt and periodic effects.

The wrapping filament is the only one that imparts the necessary cohesion – Fig. The following examples belong to the groups of threads with continuous effects: wavy threads, spiral threads, loop threads (boucle, frotte) and chenille threads. THOMANNY, U. I.; ERMANNI, P.: The influence of yarn structure and processing conditions on the laminate quality of stampformed carbon and thermoplastic polymer fiber commingled yarns. In terms of high production efficiency, the current most popular method of producing chenille threads is one based on twisting with the use of a hollow spindle. Video Lesson: Double-Faced Twill. The softness of chenille yarns makes them vulnerable to rubbing; consequently, fabrics containing them do not wear well because of a low abrasion resistance.4,15 Chenille yarns are used as crosswise yarns in a woven fabric to create a velvet-like surface or occasionally placed in the filling to add surface effects. As an adult who's crochet crazy, the idea of fancy yarns delights me. Chenille: Although tricky to knit with, this yarn … This is typically controlled by a number of structural factors including the following: the size of the effect strand, the configuration assumed by the effect strand (wavy, looped, snarled, etc. In both boucle and loop yarns, the binder strand is necessary to hold the loops in place [4]. Novelty yarns are classified according to the single or ply structure: Single yarns are Tweed and Slub Yarns. Effect . 2002). At present, these threads are mostly found in the textile industry and are known not to generate problems during the manufacturing process or subsequent processing. These threads are rich in design effects but have low usage parameters. A combination of both can produce slub/fancy yarns. For example, fancy yarns being a result of induced irregularities and discontinuities require quality constraints and testing procedures that are much less than those implemented for traditional yarns. A slub yarn is basically a spun yarn (ring or rotor-spun yarn) in which thickness variations are deliberately induced by variation in the yarn twist combined with control of the fiber feed so that thick areas will exhibit lower twist than thin areas. Another member of the group of threads with continuous effect is loop-thread. Lang Kylie is a unique natural fiber yarn with a subtle thick and thin bouclé structure. In this case, the thermoplastic core of the chenille thread is inserted in order to strengthen the hairy effect of the chenille thread and to prevent fibering off during processing on knitting machines and also during the use of knitted goods. Novelty yarns include a wide variety of yarns made with unusual features, structure or fiber composition such as slubs, inclusions, metallic or synthetic fibers, laddering and varying thickness introduced during production. consists of two or more strands of fibers held together by twist or some other mechanism ... narrow ribbon-like fabrics with one or more rows of stitched thread forming the basic structure of the yarn: Term. They are suitable for use in the production of textiles, sewing, crocheting, knitting, weaving, embroidery and rope making.However, fancy yarn deviates from the normal yarns. Each strand of single yarn is referred to as a ply; two single yarns twisted together would form a 2-ply yarn. E. Mielicka, in Advances in Knitting Technology, 2011. 2. It is also observed that the loops of frotte-type threads differ from those of boucle-type threads. Under conditions of steam and high temperature, a thin filament thread with the heat-shrinkage property can tend to get inside the yarn core and modify the structure of the smooth thread. They are made by introducing spiral forms of irregularity or hairiness into either spun continuous filament yarn. A woven fabric with a count of 144 X 76 A. is unbalanced. ASTM defines a fancy yarn as a yarn that differs significantly from the normal appearance of single or plied yarns due to the presence of irregularities deliberately produced during its formation. Sadhan Chandra Ray, in Fundamentals and Advances in Knitting Technology, 2012. Novelty Yarns: Novelty yarns are made primarily for their appearance. Such types of threads are produced by the Polish spinning industry. This thread belongs to the group of fancy threads with continuous effects – it is wavy thread produced on a base of weft knit fabrics. Fashion or novelty yarn: Any novelty structure. In loop yarns, the effect strand is usually made of long, rigid fibers that may also be lustrous, such as mohair or wool or untwisted thick filament strand. Bouclé: This highly bumpy, textured yarn is composed of loops. Hollow spindle spinning gives the possibility of integrating the two stages of the traditional ring system into one. Accordingly, fancy yarns are not necessarily intended for function-focus fibrous products. The part of the loom that controls the basic fabric structure is the A. shuttle. The compound fancy yarns shown in Fig. The manufacturing cost that may be added as a result of using these accessories is largely counterbalanced by many other factors that can indeed result in a net cost reduction. Yarns can be combined together as components of new yarns with different effects and properties from their component parts. Download : Download full-size image; FIGURE 8.8. Ply yarn. This weave can be made on a loom with only two harnesses. Y.E. Satin weave fabric always has the warp yarns floating over filling yarns. It is possible to produce multi-count and multi-twist yarns with independent servo drives to the drafting rollers, by varying the main draft and front roller speed respectively. Knitted garments have very good demand in export market. Typically, slubs are randomly and irregularly spaced along the yarn axis. D. shed. This type of yarns provides a unique surface texture to the fabric made from the yarns similar to that of linen fabrics. The fasciated structure of bouclé yarns made by using a hollow spindle machine. Classification of yarn according to structure: Continuous filament yarn Staple yarn Core spun yarn Novelty yarn Stretch yarn High bulk yarn 7. Yarn is a long continuous length of interlocked fibres, suitable for use in the production of textiles, sewing, crocheting, knitting, weaving, embroidery, or ropemaking. In weaving, the warp, or lengthwise, yarns are subjected to greater stress and are usually stronger, smoother, and more even and have tighter twist than the weft, or crosswise, yarns. Chenille yarns are also used in knit fabrics to make bulky sweater knits. 6. The introduction of a heat shrinkage thread to the structure of the fancy thread has been used in the production of chenille threads using the hollow spindle method. another term for a fancy yarn: Term. Structure of spiral or corkscrew yarn. Let's look at each of them. Yarn refers to a structure composed of continuous length of interlocked fibers. It is possible to produce a wide range of yarn structures with fancy appearance using inbuilt programs that control the servo motors in ring spinning. Nevertheless, the number of design variants of threads created from various types of fancy thread is infinite. 9.6. S-twist. Bias: the diagonal or cross grain of a woven fabric. In addition, the possibility of using a wide range of fibers including low quality fibers and a variety of fiber wastes also adds to the overall reduction in manufacturing cost [1]. ), and the core-effect arrangement used [7,18]. Satin weave creates a super smooth fabric that has a soft hand and drapes well. These devices are now available as optional accessories with most commercial spinning machines. styles and designs can be changed rapidly. 9.6d and 9.6e) exhibit a slightly wavy appearance. The binder. Fancy yarns produced by using hollow spindle machines have a similar look to yarns produced with ring twisting and the combined system, but their structure and properties are different. Novelty yarns are created by special spinning, twisting or combining these processes. In addition, the possibility of using a wide range of fibers including low quality fibers and a variety of fiber wastes also adds to the overall reduction in manufacturing cost. The effect strand in boucle yarns is usually the softest and bulkiest of this group and, typically, does not lie near the core strand. In general, fancy yarns may be divided into two major categories [4,7,18]: monofancy yarns and compound fancy yarns. Flat thread is produced using a weaving method based on plain or gauze weave with a very low production efficiency. This makes it possible for producers to make large profits very quickly. harness. The binder strand is usually small and is often not readily visible. They differ from simple yarns that their structure is characterized by irregularities. https://fibres2fabrics.blogspot.com/2013/01/construction-of-knit-fabric.html S-twist: Definition. Continuous filament yarn Continuous filament yarns are the simplest in the structure. The idea of a compound fancy yarn is to combine two or three strands together so that one of them acts as the fancy or effect strand, another acts as the yarn core and perhaps a third one acts as a binder to secure the effect strand to the core strand. Frotte threads are characterized by low resistance in comparison with boucle-type threads. In loop yarns, the effect strand is usually made of long, rigid fibers that may also be lustrous, such as mohair or wool, or untwisted thick filament strand. Chenille yarns are also used in knit fabrics for the purpose of making bulky sweater knits. These yarns can be produced using a wide range of accessories attached to commercial spinning machines. When this situation is reversed (i.e., a soft and bulky strand spiraling around a fine strand), the yarn is commonly called a spiral fancy yarn. Of the major fibers, rayon is the least likely to be Used in the handmade yarn business. Under the category of the structure of chenille threads, there are two sub-groups – chenille threads with flush pile (i.e. Regular yarns are those which have a regular straight profile and these can be twisted together, making ‘two-fold’ or ‘three-fold’ yarns for example. binder strand . Miss. Compound/Complex/Novelty Weaves Fig. Loop yarns are frequently used in coating and suiting fabrics, for interior furnishings and for specialty fabrics, either knit or woven [4]. Novelty yarns include a wide variety of yarns made with unusual features, structure or fiber composition such as slubs, inclusions, metallic or synthetic fibers, laddering and varying thickness introduced during production. You guessed it: blue. In fact, it is possible to use natural raw materials, such as cotton, but the thermal-stabilization process must then be optimized and the parameters of this process must be matched for natural fibers. Chenille yarns are usually made from cotton, wool, rayon, or polyester and are used in fabrics that are soft and velvety. Another term for a fancy yarn. The little girl in me conjures up visions of tutus, castles and lace. Seamless garments can directly be made in knitting. Novelty definition, state or quality of being novel, new, or unique; newness: the novelty of a new job. Knitted fabrics results wrinkle-free and ease-of-care garments with better form fitting and comfort. An example of this is frotte-type thread produced with a core made of PAN, joined with effective thread such as chenille, which creates the loop. Chenille: Velvety and smooth, can be tricky to knit with. B. harness. - The effect strand creates decorative detail such as knots and loops. Figure 9.6a and 9.6b represents two examples of the first type of fancy yarn, namely slub yarns and thick and thin yarns. Cotton melange yarn has been highly successful in enhancing the appeal of knitted garments such as T-shirts, etc. It has many desirable fibre properties making it an important fibre for textile applications. The wrapping of the two components (core and effect) by the filament to create a fasciated structure leads to the result that most of the elements in the fancy yarn stay parallel. Apart from these, there are many other novelty yarns like Chenille, Flake, metallic and textured yarns. The yarn structure shown in Figure 8.7 clearly shows the alternation of colours, which is the primary effect of marl yarn, as well as demonstrating the plain structure, which is that of an ordinary folded yarn. Slub yarn is basically a spun yarn (ring- or rotor-spun yarn) in which thickness variations are deliberately induced via variation in yarn twist combined with a control of fiber feed so that thick areas will exhibit lower twist than thin areas. This profile enhances the visual and textural properties of the fabric. Ring spinning, Rotor spinning, wrap spinning, Air-jet spinning etc. Spiral = Mock spiral, mouliné, jaspé, Gimp = Frisé, caterpillar, ondé, Slub = Ground slub, injected slub, injected flame (also called tear-off flame), Knop = Knot, nep, noppé, button, reverse caterpillar, flake, Loop = Bouclé, frotté, prong, mock-spun chenille, Chenille = Woven chenille, plied chenille, Figure-2: Structure of fancy yarns with type of effects, Yarn not found available or yarn delivery is delay, Fancy Yarn | Types and Classification of Fancy Yarns | Basic Principle of Fancy Yarn, Basic Parts of Sewing Machine and Its Function, Step by Step Fashion Design Development Process, Different Types of Seams and Their Uses on Garments. Computer-aided designing and manufacturing in knitting have made it possible to manufacture any desired structure within a short time at reasonable price. El Mogahzy, in Engineering Textiles, 2009. When the color-printed fragment of combed tape has been treated by this process, the color printing is elongated and blurred to produce a rainbow effect in the ready yarn. The same effect can be obtained through the use of extreme differences in tension on the ring twister frame or hollow spindle during the manufacturing process. strand that creates decorative details, knots, or loops. B. harness. For example, the corkscrew yarn shown in Fig. … In a slash yarn, the enlarged area is longer and thinner than in a nub yarn [4]. The former is made from a single staple-fiber strand or multifilament yarn in which irregularities are introduced during the conversion from fibers to yarns; the latter consist of two or more fiber strands used to provide desired combined effects. See more. The simplest among the fancy yarns, marl yarn is made by twisting two different-coloured yarns in a doubling process. Classification of Woven Fabrics. For example, the corkscrew yarn shown in Fig. In: Journal of Thermoplastic Composite Materials 17 (2004), No. A typical novelty yarn has three basic parts: 1.The ground or foundation or core. At its simplest, yarn production is essentially about taking fibres, organising them so that they lie in a lengthways direction and twisting them to create a yarn. Fashion or novelty yarn: Any novelty structure. The basic twill types: straight, point, extended point, and broken twills; ... Twill with Novelty Yarn. According to the classification, depending on the structure of the thread, there are fancy threads with continuous effects and point effects. Continuous filament yarn Continuous filament yarns are the simplest in the structure. There is also a modification of this method, which involves the periodic input of pile to obtain chenille thread with a point effect. Examples of fancy yarns [4,7,18]. In woven fabrics, the yarns may be laid so that all the tufts lie on one side of the fabric or so that some tufts appear on both the face and the back. Narrow ribbon-like fabrics with one or more rows of stitched thread forming the basic structure of the yarn. The binder strand is usually small and is often not readily visible. Similarly, a blend of fibres having varying shrinkage when combined with colour difference can also give fancy effects. Sharing Knowledge: Students, teachers and professionals can publish your article here. Time required to get an order executed is less than weaving. D. shed. 9.6J) resemble a caterpillar, hence the derivation of their name from the French word chenille, which means caterpillar [4]. Yarn producers or spinners buy in natural and/or man-made fibres to make these into yarns of different sizes and characters; regular and fancy yarns. The twisting of the core and the effect component is done during the first stage. Key structural parameters associated with slub yarns include slub size with respect to yarn diameter, slub length and slub spacing or frequency. Key structural parameters associated with slub yarns include the following: slub size with respect to yarn diameter, slub length, and slub spacing or frequency. Selvedge: The weft yarns are wrapped around the warp yarns to create an edge to the fabric, known as the Selvedge. Made of synthetic fibers these yarn blends, novelty yarns provide texture and interest. Other articles where Novelty yarn is discussed: textile: Novelty yarns: Novelty yarns include a wide variety of yarns made with such special effects as slubs, produced by intentionally including small lumps in the yarn structure, and synthetic yarns with varying thickness introduced during production. The thread is also less flexible. In addition, the importance of stimulating and attracting consumers was addressed. Plied yarns are produced by twisting two or more single yarns. Classification of yarn according to structure: Continuous filament yarn Staple yarn Core spun yarn Novelty yarn Stretch yarn High bulk yarn 7. Novelty, Speciality & Fancy Knitting & Crochet Yarn For fun, creative projects bursting with character, jump into our pool of joyous novelty, speciality and fancy knitting and crochet yarns. See more ideas about novelty yarn, yarn necklace, yarn. Nub and slash yarns have the effect strand twisted around the core strand a number of times in a small area to form an enlarged bump or “nub.” A binder strand may or may not be used. Fancy or novelty yarns are of decorative purpose. R.S. For example, fancy yarns that are a result of induced irregularities and discontinuities require quality constraints and testing procedures that are much less than those implemented for traditional yarns. Basic structure of knit fabrics Knitted fabrics are an alternative to the woven or loom fabrics. R. Alagirusamy, A. Das, in Textiles and Fashion, 2015. If it is desired, the fiber may also be combed which would be in addition to the carding. The differences in the appearance of the various yarns are largely dependent on the extent of prominence of the effect strand. For increased lustre, fibres with a flat cross-section, such as trilobal and ribbon-shaped yarns, are often employed. B. has twice as many filling yarns as warp yarns. For many years the main spinning systems could be given as woollen, worsted and cotton, and these systems gave rise to the woollen, worsted and cotton industries. Novelty effects in fabrics are in large part a result of selection of novelty yarns for incorporation into fabrics made in one of the basic weaves. The end uses include cover a broad range starting from Types of Neckties | How to Wear Men’s Tie or Neckwear to Fashion. They both have an effect strand that lies closer to the core strand than is typical in boucle and loop.4. Single yarn/staple fiber yarn / spun yarn. Figure 1 b shows the structure of interlock. 13.3). It should be pointed out that some fabric is called “chenille” even though it does not contain chenille yarns. When this situation is reversed (i.e. Fig. In general, fancy yarns may be divided into two major categories:4,7,15 mono-fancy yarns and compound fancy yarns. Novelty: Novelty yarns are easy to recognize because their appearance is so different from traditional yarns: Ribbon: A knitted ribbon in rayon or a rayon blend. Such ring-spinning machines are in operation all around the world. It should be pointed out that some fabric is called ‘chenille’ even though it does not contain chenille yarns. Novelty yarns, typically made of two or more stands, are produced to provide decorative surface effects. In Chapter 3, a number of important business and marketing issues related to product development were discussed. They add interest to any knitted garment. Both gimp and ratiné yarns (Fig. Yehia E. Elmogahzy, in Engineering Textiles (Second Edition), 2020. … In order to improve the design potential in this group of yarns, new heat-shrinkable components are inserted at the last stage of the production process. Single yarns include spun, monofilament, and multifilament yarns. 9.6D and E) exhibit a slightly wavy appearance. Figure-6: Gimp yarn: Although it is common to overfeed the effect in the first twisting stage, this is not essential. This is typically controlled by a number of structural factors including the size of the effect strand, the configuration assumed by the effect strand (wavy, looped, snarled, etc.) They are made of artificial yarn blends and provide texture. Textured and many other fancy yarns can easily be knitted and converted to light weight fashion garments. Generally, this yarn involves a strand or two of "normal" yarn combined, often by twisting, with something else to create a more interesting color pattern or texture. This type of yarn provides a unique surface texture to the fabric made from the yarns similar to that of linen fabrics. These yarns … Natural fibres, including some linens, wools to be woven… Boucle yarns are found in both woven and knit fabrics that are often called boucle fabrics. Manufactured By a solution in … Fancy yarns, also called novelty or effect yarns, represent another category of yarns in which deliberate irregularities, discontinuities, and color variations are introduced into the yarn structure with the primary intention being the production of enhanced aesthetic and fashionable impressions [4,7,18]. Compound fancy yarns can be found in unlimited number of varieties and textures. Unfortunately, the introduction of thermoplastic thread to the structure of chenille raises the price of the yarn and only a few producers of chenille thread can afford to adopt such an innovation. Figure 8.8 shows the basic structure, which is straightforward, except in the differing lengths of the two yarns involved, and is very similar to the structure of a marl yarn. Fancy yarns have wide-ranging application in apparel at all levels of the market. harness. From a comparison of the external appearance of boucle and frotte threads made from the same raw materials and at the same parameters of the twisting frame machine, it can be seen that the threads of the boucle type are more attractive, but are thicker and more rigid. An example is boucle yarn, formed by allowing one yarn to form loops around a core or central yarn, while a third yarn holds or binds these two yarns together. 2002, Petrulytė and Petrulis 2004). Slub yarns are made by uneven twisting of yarns creating thick and thin areas. Academia.edu is a platform for academics to share research papers. The effect is composed of tufts of yarn held between plied yarns that form the core of the chenille yarn. In woven fabrics, the yarns may be laid so that all the tufts lie on one side of the fabric or so that some tufts appear on both the face and the back [4]. E. batten. that ties the effect yarn to the base yarn if binding is necessary. For details: Submit Article. The difference between these two types of thread derives from differences in the production process. Novelty yarn is a relatively new trend that has enabled a variety of new looks for knitters who prefer to depart from traditional yarn. UN-2 Under intense pressure from the textile industry in the United States, the NAFTA agreement however ushered in a novelty in rules of origin, the so-called “ Yarn Forward” rule. Single yarn, the simplest type of yarn, is commonly produced by twisting together staple or filament fibers. A blend of cotton, silk, wool, and viscose, this yarn will add texture to knit and crochet projects. They are as follows: 1. A thick and thin yarn is typically a multifilament yarn in which diameter variations are deliberately induced via variation in the filament flow rate through the spinneret during extrusion. Novelty yarns are available in different types of colors and textures. having or displaying novelties: novelty … Structure of Cotton Fiber: Cotton, the seed hair of plants of the genus Gossypium, is the purest form of cellulose readily available in nature. By mechanically assembly or twisting of staple fibers together spun yarns are made. The effect is composed of tufts of yarn held between plied yarns that form the core of the chenille yarn. of or pertaining to novelties as articles of trade: novelty goods; novelty items. A snarl yarn uses a twist-lively strand to form the projecting snarls. The floating yarn is then passed under one of the opposite yarn before repeating the process again. Chenille yarns are used as crosswise yarns in a woven fabric to create a velvet-like surface or occasionally placed in the filling to add surface effects. Fancy yarns are invariably used to create fashion fabrics. The core strand in loop yarns is usually coarser and heavier than in boucle yarns. (Fig. a soft and bulky strand spiraling around a fine strand), the yarn is commonly called a spiral fancy yarn. KNIT Which of these stitches is used to create color effects or structural designs? Colour effects along the yarn length are introduced by twisting different coloured yarns, spinning blended dyed fibres, or by irregularly printing/dyeing spun yarns. - The effect strand creates decorative detail such as knots and loops. 5. A binder strand may or may not be used. 9.6A and B represents two examples of the first type of fancy yarns, namely, slub yarns and thick and thin yarns. These fabrics are essentially tufted and they are often used for bathrobes and bedspreads. In the context of design, it is important to point out that in addition to the deliberate irregularities induced in fancy yarns, fiber strands with different physical characteristics can also be used to make fancy yarns. Carry along feathers, loops or eyelash yarns to create new textures and bring drama to your garments. The production efficiency of these types of threads when applied in modern production techniques (hollow spindle) is very high, and could even reach 200 m/minute (meters per minute), in comparison with the classical method (ring twisters method), reaching 15 m/minute at most. 4 Figure 2 - Textured Filament Yarn. We use cookies to help provide and enhance our service and tailor content and ads. Crepe Fabrics Crepe weave fabrics is special novelty fabrics from basic weaves may be defined as fabrics characterized by a crinkled, pebbly surface. Basic interlock knitted structure is a double 1/1 rib fabric (Figure 1 a, b). This simple, crew-neck, drop-shoulder, bottom-up, seamed cardigan can be worked in any gauge with any weight yarn, though it’s shown here in a worsted weight. Chenille yarns (Fig. Boucle, loop, and snarl yarns shown in Fig. (of a fabric or garment) having a pattern or design produced by a novelty weave. The hollow spindle method is one of the four methods, together with ring spinning, the combined system and the chenille method, for production of fancy yarns (Gong et al. covered by . Textile - Textile - Classification based on use: Almost any textile yarn can be used to produce such interlaced fabrics as woven and knitted types. In both boucle and loop yarns, the binder strand is necessary to hold the loops in place. The common kinds of novelty yarns are: Chenille-It is smooth and velvety and can be tricky to work with. Others are produced using special spinning preparation in which blends of various fiber colors or fiber types forming fancy slivers are used. Novelty yarns are usually uneven is size, varied in color or modified appearance by their formation. strand that provides structure and strength. There is currently a tendency towards making combinations of various types of fancy threads in various structural systems. These fabrics are essentially tufted, and they are often used for bathrobes and bedspreads [4]. This group contains threads known as frotte.
