filament yarn characteristics

Following property and classification shows the definition and types of filament yarn. Fibre length is used to broadly divide yarns into: – Spun yarns (made from short, staple fibres) – Filament yarns (made from continuous filament … Ana sayfa » News » What is Filament Yarn? 2 Production processes for filament yarns . Fabrics made of filament yarn are usually shinier and smoother than of spun yarn because you do not have the ends of fiber on the fabric, there is no nap at all. This is calculated weight which does not include: A. Shrinkage caused by weaving (about 5%) More uniform in diameter than spun yarn. The size of yarn is usually related to the weight of the fabric, for example, heavy fabrics use thick yarns and for light fabrics a fine yarn is used. Types of yarns include spun yarn and filament yarn. Filaments yarns square measure divided into 2 varieties viz flat continuous filament and rough-textured continuous filament yarn. These are much longer than staple fibers. ——————————— = ——————————— (2) Hygroscopicity is larger than smooth filament. By using the yarns which had been ranked grade 2 to grade 6 in Example 6, the change of filament yarn in tensile characteristics was investigated by means of irradiating the yarn in fade-o-meter for 180 hours. Thick to thin diameters. To change their properties, filament yarns can be textured or "bulked." The self-twisted staple core is initially wrapped with a filament yarn in alternating S and Z phases; a second filament yarn is then wrapped around these in alternating opposite Z and S twists. Their smooth nature gives them more luster than spun yarns, but the luster varies with the amount of delustering agent used in the spinning solution and the amount of twist in the yarn. Industrial yarns are considered to be the ultimate discipline in filament manufacturing. This should all be taken into consideration when you try to determine the weight of the fabric. It is used for the clothing of fire fighter, fuel handlers, welders, racing car drivers. There are differences between spun yarn and filament yarn that will be highlighted in this article. From the above we see that, technical filament yarn’s properties are higher than conventional yarn. When it comes to printing with filament nylon, it is as easy as when you print with ABS filaments. The big number is the thick size, small number, the small size. Yarns are produced in various sizes and textures, and also vary in other characteristics. 52.9 gram x 0.0352 oz =1.862 oz per square yd. The effect yarn has the loops wrapped around a core, or base yarn, and then the third ply, or binder, is wrapped over the effect ply in order to hold the loops in place. Deformation filament yarn. It is used for the clothing of fire fighter, fuel handlers, welders, racing car drivers. B. Shrinkage caused by dyeing (about 3%).

The test results can also be used to consider the consequences on subsequent processes. Thanks to the gloss of the fibre it is ideal for glittery and silky fabrics, ribbons and trimmings. Calculation of fabric weight made of filament yarn: – when nylon 6 and nylon 6.6 solutions are extruded through one spinneret hole, a filament is obtained which consists of both the polymers attached side by side. 70d x 140d 70d x 70d, And divide 140d by =2 C. 260 divided by 150 = 2.48 oz per square yard. Made from natural silk fibers. Multifilament yarns are composed of bundled individual filaments. display: none !important; There is also a variety of finishes to give them low wick characteristics, make them flame retardant, food compliant or UV resistant. one Filament Testing, On-line monitoring - Filament . Texturized yarns are made by a process of air texturizing filament yarns (sometimes referred to as taslanizing), which combines multiple filament yarns into a yarn with some of the characteristics of spun yarns. The yarns have the same numbers are in Example 6 and they are all 120 denier yarns. Nylon or other synthetic filament is made from a process called extrusion by which you can make the filament thick or thin. Filament yarn usually comes in 70 denier and 140 denier (or 160 denier). Spin-staple yarns consist of staple fibers assembled and bound together by various means (usually twist) to produce the required characteristics such as strength, handle and appearance . Regularity or evenness of the yarn, 6. For full treatment, see textile: Production of yarn. 36” x90 pcs of weft threads =3240 yards of 70d yarn. Twist in yarn, 4. 3 . (Warp) x (weft) (Warp) x (weft) Types of filament yarn. More uniform in diameter than spun yarn.  +  However, if the fabric has some kind of finish on it, such as water repellence or water proof finish, the weight is increased slightly. Here is a short cut formula to do the same weight calculation: A convert all yarn sizes to 70d and adjust the warp and weft thread numbers accordingly. 2. Equal number of filaments throughout. Continuous filament yarns in fabric form usually have excellent strength & uniformity. C divide the total by 105 (this is a constant used in the formula regardless of weight or construction of the fabric) to get weight of the fabric per square yard in oz. The results are shown in Table 7. Softer and more pliable than spun yarns. Optical sensor for real time online monitoring of defects and vital characteristics of filament yarn. These are only some of the main characteristics of staple and filament fibers and their end uses, however, there are many other options, especially for textile fiber, whether it is mixed or pure. Filament Yarn. Twist variation in yarn, 5. Silk is a natural filament, and synthetic filament yarns are used to produce silk-like effects. It is a publicly listed company on the Pakistan Stock Exchange (PSX) with its manufacturing facility located in the city of Hub, Balochistan, on the outskirts of Karachi. The filament is composed of both the fibers. Our customising service is pleased to develop yarns geared to your products. Filament yarns have a limited number of filaments that are extruded from a spinnerette device as shown in Figure 1. Provides lustrous, shiny or gossamer-sheen appearance. Thread number per inch : 120 x 70 Filament yarns generally require less twist than staple. Stronger than spun yarn of the same diameter. Part II: Yarn Characteristics Introduction The end product of the cotton fiber-to-yarn conversion system is a spun yarn or a staple-fiber yarn, which is suitable for making numerous end products from knit apparels to woven fabrics, from towels to sheets, and from carpets to industrial fabrics. Performance, end use, and fabric care are affected by these yarn characteristics. Nylon printing produces really nice prints. People also use the term filament yarn that confuses laymen. Regularity or evenness of the yarn, 6. From the above we see that, technical filament yarn’s properties are higher than conventional yarn. Mono filament yarn is a single strand of filament form yarn and multi filament yarns are composed of two or more filament strands twisted, plied or yarns twisted together to form one yarn.

Characteristics of textile filament yarns: Composed of long continuous fibers. Filament yarn are two types: mono filament yarn and multi-filament yarn. Thin place in yarn, 10. Made from man-made fibers. More uniform in diameter than spun yarn. Yarn is selected for different textiles based on the characteristics of the yarn fibres, such as warmth (wool), light weight (cotton or rayon), durability (nylon is added to sock yarn, for example), or softness (cashmere, alpaca). Thicker mono filaments are generally used for industrial purposes rather than fabric production or decoration. }. In the following example you should divided 140 by 70 and get 2 and then multiply the warp thread number by 2 and get the following: A. May be bundled into a ‘tow’ which will be cut into staple size. Yarn count, 2. This makes them softer, stretchier, more resilient, and more like staple yarns. They tend to be the most compact and smooth of all types of yarns (Fig. At present, the sizes of filament commonly produced are about the following: Therefore for 70d yarn, you can use 17 pieces of 4 denier filament to form the yarn, or 24 pieces of 3 denier or 34 pieces of 2 denier, or 68 pieces of 1 denier to form one piece of 70d yarn with the size and weight almost identical.
