Polypropylene: - Abbreviation- PP. The isotactic PP chips produced by various polymerizing processes can, as with PA and PET, be spun by the melt spinning process into multifilaments and staple fibers and also spunbounded fabrics.
Rayon Fiber: A manufactured fibre composed of regenerated cellulose, as well as cellulose in which substituents have replaced by not more than 15% of the hydrogens of the hydroxyl groups. Rayon Fibres include yarns and fibres made by the viscose process, the cuprammonium process and the now obselete nitrocellulose and sapnofied acetate process. Generally in the manufacture of rayon, cellulose derived from wood pulp, cotton linters or other vegetable matter is dissolved into a viscose spinning solution. The solution is extruded into an acid-salt coagulating both and drawn into continuous filaments. Groups of these filaments may be made in the form of yarns or cut into staple.
Draw Warping: - Process in which yarns are drawn and warped is one operation, thereby eliminating draw-twisting machine processing.
Warp Knitting: A type of knitting in which the yarns generally run lengthwise in the fabric.
Extruder: - Machine used in melt spinning which melts the granules with a screw-type spindle, heats up the melt to a prescribed temperature, and homogenizes it, finally feeding it under pressure to the spinning pump.
Space-dyeing: - Overall term for yarns or tow which are dyed or printed by various processes, applied in different shades and at different intervals and lengths (without repeats). Irregular motifs and imaginative effects are produced after weaving or knitting.
MOY: - Abbreviation of Medium Oriented Yarn.
