“…What the research paper shows is the fact that the knitting industry did not know the fiber shedding. What made it relatively unknown was the way polyester filament was used in the knitted fabric production during its boom period some time before 1979 [1]. Yet, when the cotton knitwear was back in great demand in global fashion, then the manufactures were put into a great trouble due to the problem of fiber shedding [2].…”

When providing care, to protect a part of the human body against resins and plas ters for certain time, it is necessary to use a circular knitted band in cotton as a raw material. The generating of Cotton fiber fly throughout the knitting process is due to interactions of frictional surfaces with the hairiness of ring spun yarn. During the manufacture short fibers are formed in the machine device, this problem is more important with the use of cotton yarns. In this research paper, the short fibers formation on circular knitting machines from spun yarns such as cotton is investigated The knitting conditions consist of; yarn tension, yarn feeding speed and the angle contact of the yarn with guides and needles. The results obtained illustrate the effect of yarn tension on the short fibers deposit caused by the combination of yarn friction with the knitting elements.

Polyamide fibers are melt‐spun from linear thermoplastic polymers having recurring amide groups made from diamines and dicarboxylic acids or lactams. Polymer made by the polycondensation of hexamethylenediamine and adipic acid is designated nylon‐6,6; that made from ε‐caprolactam, nylon‐6. These polymers account for about 98% of the total 3.9 million tons of worldwide production of nylon fiber. The attributes of nylon fiber, such as high strength, durability, abrasion resistance, resilience, ease of dyeability, and low specific gravity, have been recognized since its introduction in 1938. Both the inherent properties and those properties that can be engineered into the fiber through manufacturing and ultimately into the fabric article in downstream mill processing account for the diverse end uses of nylon. These include hosiery, lingerie, skiwear, activewear, swimwear, carpets, tire cord, luggage, upholstery, automotive air bags, interliners, and military uniforms. Nylon fiber is manufactured by extruding molten polymer through a filter pack multihole spinneret assembly and then drawing (or stretching) the filaments as a separate or continuous process to fix the size and physical properties (tenacity, elongation modulus) of the filaments (or yarn) for a particular end use. The product is offered as continuous flat yarn or, through additional manufacturing steps, as crimped staple, tow, or precision‐cut flock. Continuous‐filament (flat) yarn can be used as is, or, for most applications, textured for bulk and/or stretch. Physical appearance, functionality, and performance of nylon filaments can be modified by incorporating additives, eg, delusterants, colorants, antioxidants, and antistats, in the polymer or directly to the melt stream prior to extrusion, by designing a spinneret hole to impart a desired luster or surface effect or by spinning bicomponent or biconstituent fibers. Very fine fibers (0.2 dtex = 0.18 den), are made by spinning biconstituent conjugate fibers with nylon and polyester and dissolving the polyester in an alkali fabric treatment. The introduction of direct melt‐spun 0.88–2.22‐dtex (0.8–2.0 den) nylon products in the mid‐ to late‐1980s had a significant positive effect on the apparel market. Other breakthrough technologies, such as high speed spinning of partially oriented yarns for draw texturing, nylon‐4,6 for industrial yarn applications, soil‐ and stain‐resistant nylon carpets, utilization of available 47–93‐tex (420–840‐den) industrial yarns for an emerging automotive air bag industry, have all contributed to the growth of nylon fibers since the 1980s. The commitment made by the textile industry to recycle fibers and fabrics and to conserve materials and minimize landfilling in compliance to regulatory legislation will have a profound effect on how fiber producers design their offerings for the future.
