Textured Filament Yarn Processing Machinery
topic
False-twist texturing machines process thermoplastic multifilament yarns through a heated draw zone, a false-twist spindle that inserts and removes twist simultaneously creating a permanent helical crimp from the heat-setting in the twisted state, and a cooling zone fixing the helical crimp before untwisting, producing textured yarn with 30 to 60 percent bulk increase and elastic recovery for hosiery, knitwear, and sportswear applications.
Role
Converts flat smooth multifilament synthetic yarns into bulky, elastic, and texturally complex yarns that provide the softness, bulk, and extensibility needed for apparel and hosiery applications, with false-twist texturing being the dominant texturing process worldwide producing the textured polyester and nylon yarns used in the majority of knitted synthetic apparel and hosiery fabrics.
