HUEC 2040 Chapter : Chapter 10 YARN PROCESSING
Document Summary
Yarns: short staple or long filament fibers formed into long continuous strands. Combing- additional step using a comb, aligns fibers. Not as strong as hand spun ,not for warp. Yarns- continuous strand of textile fibers filaments , or materiela in a form suitable for knitting. ,weaving , or otherwise interwining to form a textile material. Smooth filament yarns: regular or conventional filament yarns. Production- used as produced , no further processing required. Used in smooth , lustrous fabrics or where high strength ,compact yarns are needed. Network yarns similar to tape yarns, but with gre. Bulk yarns: bulk continuous filament (bfc) yarns / greater covering power or apparent vol. compared to smooth filament yarns. Characteristics= less smooth/more permeable to air and liquids: less slippery /more comfortable/absorbent/less static prone, more bulk,cover and elasticity. False twist- continuous process: yarns are twisted,heat set, untwisted, widely used method and most common, adds bulk and stretch to filament yarns.
