The differences in the appearance of the various yarns are largely dependent on the extent of prominence of the effect strand. It is also observed that the loops of frotte-type threads differ from those of boucle-type threads. These yarns are used to make discreet pinstripes in men’s suiting or to produce a subtly and irregularly patterned knitted fabric with a relatively simple fabric construction. Both the appearance is the same on both sides. The fancy or effect 3. o. Novelty yarn is a relatively new trend that has enabled a variety of new looks for knitters who prefer to depart from traditional yarn. Manufacture of fancy yarns often involves plying and cabling together different yarns of varying counts and twists. Various fancys By definition, fancy yarns are any type of yarn with a deliberate interruption or discontinuity in color or form. In the context of design, it is important to point out that in addition to the deliberate irregularities induced in fancy yarns, fiber strands of different physical characteristics can also be used to make fancy yarns [4,7]. Novelty yarns, typically made of two or more stands, are produced to provide decorative surface effects. The core strand in loop yarns is usually coarser and heavier than in boucle yarns. Ring spinning, Rotor spinning, wrap spinning, Air-jet spinning etc. A snarl yarn uses a twist-lively strand to form the projecting snarls. Devices used to create these types of yarn have been available since the 19th century. Currently, customers of fancy yarn are especially interested in KDK thread (Knitt de Knitt). It is a platform to express your knowledge throughout the world. knit - basic stitch; wales = front, courses = back 2. purl - reverse of knit stitch courses = front, wales = back 3. miss - float stitch used to create color effects 4. tuck - elongated skipped stitch that creates holes in fabric; used to create lacy, textural design effects. The effect is composed of tufts of yarn held between plied yarns that form the core of the chenille yarn. effect filament. Novelty yarns are available in different types of colors and textures. Fancy yarns are produced with a multiplicity of structural features but the structure of a fancy yarn may be considered in terms of the following three basic components (Fig. Advanced Yarn Manufacturing Azmir Latif, MSc in TE Figure 9: Structure of Slub Yarn Fasciated Yarn Fasciated yarn is a staple fiber yarn that consists of a core of a parallel fibers bound together by wrapper fibers. 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. 5. 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. Sharing Knowledge: Students, teachers and professionals can publish your article here. 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. Binder yarns which are used in novelty-type yarns, such as bouclé yarns, to hold the loops, or in fancy/effect yarns to the core or base, are also considered as a reinforcement yarn. Thus, the core and the effect components pass through a roller drafting unit (though having different paths) and enter the axial inlet of the hollow spindle. A return to our classic Basics line, this time for crochet! Novelty definition, state or quality of being novel, new, or unique; newness: the novelty of a new job. Developments in spinning, however, have led to new spinning systems including ‘open-end’, ‘self-twist’ and ‘jet’ spinning. E. batten. This technique has an efficiency of 18 m/minute and makes it possible to produce round chenille threads with various lengths of pile along the yarn. When this situation is reversed (i.e. Fashion or novelty yarn: Any novelty structure. The evaporation of the ready yarn produces a wavy effect in the fancy thread. Many novelty yarns are composed of: o. Base/core . Corkscrew, spiral, chenille, gimp, loop, snarl and boucle have all found acceptance in apparels and for the production of furnishings and upholstery. Chenille yarns (Fig. 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. Fancy yarn, sometimes known as novelty yarn is a yarn that is made with a distinctive irregular profile or a construction that differs from basic single and folded yarns, the objective of which is to enhance the aesthetics of the end product with respect to visual and textural properties. ), and the core-effect arrangement used [7,18]. In both yarns, the effect strand is twisted around the core strand, but ratiné yarns are usually larger and wavier than gimp yarns due to a larger effect strand. 2. Textile - Textile - Classification based on use: Almost any textile yarn can be used to produce such interlaced fabrics as woven and knitted types. This profile enhances the visual and textural properties of the fabric. Knitted garments have very good demand in export market. Well you're in luck, because here they come. In these types of threads the pattern-effect of the yarn is applied to the whole length of the thread. There is also a modification of this method, which involves the periodic input of pile to obtain chenille thread with a point effect. If you're striving for the smoothest, most even worsted or the loftiest woolen yarn, stopping to add in locks without drafting them or even tossing some commercial yarn into the mix may seem like a distraction. 4,7,15 Accordingly, fancy yarns are not necessarily intended for function-focus fibrous products. e.g. This explains why it has a greater bending stiffness and a lower ability to form waves. 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. 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. The thread is also less flexible. 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. The part of the loom through which the filling yarn is inserted is the A. shuttle. The twist of the effect strand is usually in the same direction as the twist that holds the effect and core strands; the binder strand is usually twisted in the opposite direction [4]. Fancy effects can also be created by changing fibre specifications such as type, length, denier, cross-sectional shape, crimp, initial modulus, colour, lustre, affinity for dyes and shrinkage, etc. Simple yarns consist of single or plied yarns that are uniform in size, smooth and have an equal number of twists and turns along the strand. Grain: runs the length of the fabric. 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. The basic twill types: straight, point, extended point, and broken twills; ... Twill with Novelty Yarn. Seamless garments can directly be made in knitting. 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. By continuing you agree to the use of cookies. Both gimp and ratiné yarns (Fig. Figure 1 b shows the structure of interlock. Such combinations cause the price of thread to rise considerably, and dramatically increase the linear density of thread. 13.4. Novelty bulky yarns may make the fabric hard to handle. 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]. The classical ring system for production of fancy yarns includes two stages. Frotte threads are characterized by low resistance in comparison with boucle-type threads. 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. 9.6. 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. Video Lesson: Twill Gamps. Fancy yarns are made with a distinctive irregular profile which is different from basic single and folded yarns. They are made by introducing spiral forms of irregularity or hairiness into either spun continuous filament 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. El Mogahzy, in Engineering Textiles, 2009. It should be pointed out that some fabric is called ‘chenille’ even though it does not contain chenille yarns. 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. 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. B. has twice as many filling yarns as warp yarns. Novelty yarns include a wide variety of yarns made with unusual features, structure, or fiber composition. Thread is a type of yarn intended for sewing by hand or machine.Modern manufactured sewing threads may be finished with wax or other lubricants to withstand the stresses involved in sewing. In general, fancy yarns may be divided into two major categories:4,7,15 mono-fancy yarns and compound fancy yarns. 9.6F–H, respectively, have dramatic effect strands [4,18]. - The base/core strand provides the structure and strength. Texturized yarns made exclusively from continuous filaments can also be considered as a form of fancy yarn. 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. 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]. C. reed. 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. Fashion or novelty yarn: Any novelty structure. E. Mielicka, in Advances in Knitting Technology, 2011. They are used in ladies outerwear, mens jackets, knitwear, ties, furnishings, curtains and upholstery. Lang Kylie is a unique natural fiber yarn with a subtle thick and thin bouclé structure. Chenille yarns (Fig. Compound fancy yarns can be found in an unlimited number of varieties and textures. Bouclé: This highly bumpy, textured yarn is composed of loops. 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. 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. In Chapter 3, a number of important business and marketing issues related to product development were discussed. Apart from these, there are many other novelty yarns like Chenille, Flake, metallic and textured yarns. 4 Figure 2 - Textured Filament Yarn. There is a wide variety of novelty yarns that are produced using different techniques and … If it is desired, the fiber may also be combed which would be in addition to the carding. Jul 15, 2020 - Explore Martha Vickery's board "Novelty Yarn Patterns" on Pinterest. The effect is composed of tufts of yarn held between plied yarns that form the core of the chenille yarn. These yarns can be produced using a wide range of accessories attached to commercial spinning machines. https://fibres2fabrics.blogspot.com/2013/01/construction-of-knit-fabric.html The second stage involves the twisting of the binder around the first two components, thus fixing the effects and giving additional strength to the final yarn. All the yarns listed may be found in any fiber. It differs in texture from normal double yarn. 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. Yehia E. Elmogahzy, in Engineering Textiles (Second Edition), 2020. Of the major fibers, rayon is the least likely to be Used in the handmade yarn business. A typical novelty yarn has three basic parts: 1.The ground or foundation or core. The following examples belong to the groups of threads with continuous effects: wavy threads, spiral threads, loop threads (boucle, frotte) and chenille threads. 9.6f, 9.6g, and 9.6h, respectively, have dramatic effect strands.4,15 The effect strand in boucle yarns is usually the softest and bulkiest of this group and, typically, does not lie near the core strand. This is one type of novelty yarn. You guessed it: blue. Boucle yarns are found in both woven and knit fabrics that are often called boucle fabrics. The common kinds of novelty yarns are: Chenille-It is smooth and velvety and can be tricky to work with. 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.) These yarns are providing us with a huge variety of surface ornamented fabrics at a low cost. A basic weave, characterized by long floats of yarn on the face of the fabric. 1 . Fancy yarns have wide-ranging application in apparel at all levels of the market. Continuous filament yarn Continuous filament yarns are the simplest in the structure. Novelty or fancy yarn 11. 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. Slubs of varying dimensions can be produced by using differential fibre length in the core and effect components. May 26, 2019 - Explore Leslie Carey's board "novelty yarns", followed by 153 people on Pinterest. strand that provides structure and strength. 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. The development of fancy yarns represents a model example of how a market can be dynamically stimulated using creative ideas that can attract consumers and draw attention to the products with minimum added cost. D. shed. 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. 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. Boucle, loop, and snarl yarns shown in Fig. There can be endless variety of novelty yarns. Novelty Yarns. It is important to underline the constant high level of interest in mélange threads where the change of thread color and shading takes place continuously. Additionally, what is fancy yarn in textile? Fig. These fabrics are essentially tufted, and they are often used for bathrobes and bedspreads [4]. - The effect strand creates decorative detail such as knots and loops. Narrow ribbon-like fabrics with one or more rows of stitched thread forming the basic structure of the yarn. By combining fibre types, and using different spinning systems and machinery, yarns can be developed with individual profiles suitable for a vast range of end uses.

Yarn refers to a structure composed of continuous length of interlocked fibers. 1. 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. It is composed of two 1/1 ribs interlocked together with crossed sinker wales (Figure 1 a). There are 5752 novelty yarn for sale on Etsy, and they cost $5.14 on average. 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. Made of synthetic fibers these yarn blends, novelty yarns provide texture and interest. 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. In general, there are three basic classifications. The basic structure of a gimp yarn is illustrated in Figure-6 . As noted from the definition most fancy yarns are either single or plied. The little girl in me conjures up visions of tutus, castles and lace. Download . Novelty yarns are created by special spinning, twisting or combining these processes. A thick-and-thin yarn is typically a multifilament yarn in which diameter variations are deliberately induced by variation in the filament flow rate through the spinneret during extrusion. in the manufacturing of pillar stitch warp knit fabrics or in the introduction of weft thread as a pile. Chenille yarns are also used in knit fabrics for the purpose of making bulky sweater knits. In general, fancy yarns may be divided into two major categories [4,7,18]: monofancy yarns and compound fancy yarns. Pinter has developed a small ring-spinning machine – ‘Merlin’ – with six or 48 spindles that allow it to work with a range of fibres to produce all types of special yarns and their combinations: slub (multi-count and multi-twist), core spun, devore and double rove yarns. TEXTILE SPINNING Textile Technology knowledge series Volume II TEXCOMS TEXTILE SOLUTIONS APRIL 21, 2019 The compound fancy yarns shown in Fig. Structure of Cotton Fiber: Cotton, the seed hair of plants of the genus Gossypium, is the purest form of cellulose readily available in nature. Novelty Yarn comes in a variety of colors and textures and add interest to a knitted garment. See more ideas about novelty yarn, yarn necklace, yarn. 9.6C typically has a fine strand spiraling around a soft and bulky strand. Single yarn, the simplest type of yarn, is commonly produced by twisting together staple or filament fibers. Each strand of single yarn is referred to as a ply; two single yarns twisted together would form a 2-ply yarn. All the yarns listed may be found in any fiber. fWHAT ARE NOVELTY YARNS? Chenille: Velvety and smooth, can be tricky to knit with. Classification of yarn according to structure: Continuous filament yarn Staple yarn Core spun yarn Novelty yarn Stretch yarn High bulk yarn 7. 3.0 Staple Spinning Systems 3.1 Ring Spun Yarns The processing of a cotton ring spun yarn must go through a carding machine. Time required to get an order executed is less than weaving. Knitting is more flexible than weaving, i.e. Typically, slubs are randomly and irregularly spaced along the yarn axis. 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. Fancy yarns are invariably used to create fashion fabrics. 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. The effect strand in boucle yarns is usually the softest and bulkiest of this group and, typically, does not lie near the core strand. Novelty yarn. According to the classification, depending on the structure of the thread, there are fancy threads with continuous effects and point effects. Yarns made under the air jet spinning method are of this structure. Common types of Novelty Yarns: Bouclé: Loopy and bumpy. 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. (of a weave) consisting of a combination of basic weaves. Boucle yarns are found in both woven and knit fabrics that are often called boucle fabrics. and the core-effect arrangement used.7,15 The compound fancy yarns shown in Fig. 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 the third one acts as a binder to secure the effect strand to the core strand. In both yarns, the effect strand is twisted around the core strand, but ratiné yarns are usually larger and wavier than gimp yarns owing to a larger effect strand. The end uses include cover a broad range starting from flat chenille threads) and cylindrical chenille threads, where the pile is distributed regularly and spatially around the longitudinal axis. 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. Let's look at each of them. Bouclé- Bumpy and loopy. Continuous filament yarn Continuous filament yarns are the simplest in the structure. 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 to produce enhanced esthetic and fashionable impressions.4,7,15 Accordingly, fancy yarns are not necessarily intended for function-focus fibrous products. These fabrics are used for many products such as dresses, draperies, and bedspreads. Labour compliment requirement is less in knitting; hence problems related to labour are less. Sublime Stitches Part 2: Basic Embroidery Stitches In the Spring 2016 issue of Spin Off, Kate Larson shared tips for embroidering with your handspun yarns. having or displaying novelties: novelty … Effect of Yarn Twist Direction and Woven Design on Certain Novelty Fabrics from Cotton/Polyester Trilobal Filament 3-ply Yarn ... because of the loose structure of the sateen weaves. C. reed. that ties the effect yarn to the base yarn if binding is necessary. 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’. Plied yarns are produced by twisting two or more single yarns. For details: Submit Article.
