Manufacturing of Manmade Fibers

fiber spinning Manmade fibers are manufactured using different mechanical and chemical processes for example Synthetic fibers from thermoplastics are produced by extruding the molten plastic through extrusion dies (spinnerets) into a stream of cold air that cools and solidifies the plastic. (The operation is referred to as melt spinning.)

Open-End Spinning

spinning spun-yarn yarn The first functioning of rotor spinning ,machine was presented at the ITMA in 1967.Yarn spinning according to the rotor spinning principle predominates for all non conventional spinning methods.It omits the step of forming a roving.After drafting, the sliver is fed into a rotary beater.This device ensures that the fibers are beaten into a thin supply which enters a duct and gets deposited on the sides of the disc(rotor).The transportation of the fibers is achieved through air currents.

Substrate Formation

knitting spinning weaving yarn Textile substrates are formed from yarns or fibre webs by several techniques including weaving, knitting, tufting, and nonwoven formation. Composites of textile substrates are formed by bonding two fabrics together by use of an adhesive to form a bonded substrate or backed substrate or by application of cut fibres to an adhesive-coated substrate to form a flocked substrate.

Air Jet Spinning

air-jet-spinning spinning yarn Air jet spinning has offered yarn manufacturers the opportunity to produce yarn at relatively high production rate. Unlike other spinning methods in which productivity is limited by the amount of twist in the yarn, Air Jet yarns can be produced at the same production rate regardless of yarn counts. Murata Vortex Spinners are one such leading Air Jet spinning machines which excel at producing finer yarns (Ne 40/1-60/1), because of the improved strength imparted to the smaller fibre bundle.

Fiber Process
