Method for manufacturing elastic ultrathin filament textured yarn and the elastic ultrathin filament textured yarn manufactured from the same

Abstract

This invention discloses a method for manufacturing ultra-thin fiber yarn having elastic characteristics. Ultra-thin fiber Textured Yarn and thermoplastic fiber are concurrently fed into a compression air jet system to produce elastic ultra-thin fibers. The two materials are made into a novel yarn with elastic function using the process of this invention, which is simpler as compared with other traditional processes associated with manufacturing elastic complex yarn. The process of this invention is capable of manufacturing elastic complex yarns with excellent size stability, capable of being easily woven, suitable for the textile and slopwork industries, and capable of producing textiles with good elasticity and high degree of comfort.
