Process for Manufacturing Short Fibers of Poly (terephthalate trimethylen) and short Fibres, Yarns and Fabrics of Poly (trimethylen Terephthalate)

摘要

A process for the manufacture of short Fibers of Poly (trimetilu00e9n Terephthalate) comprising: (a) provide Poly (trimetilu00e9n Terephthalate); (b) melt spun Poly (trimetilu00e9n Terephthalate) Melted at a temperature of 245 - 285 degree C to form filaments; (c) to cool the filaments Stretch l; (d) Os filaments cooled; (e) The stretched filaments using a Curling Team Mechanic a Curly NIVThe Curl Curl - 30 8 per inch (3 - 12 Curls by cm); (f) relax curled filaments at a temperature of 50 to 120 degree C; and (g) Cut filaments relaxed in short Fibers that have a length of approximately 0.2 to 6 inches (approximately 0.2 to 6 inches (approximate Mind 0.5 to approximately 15 cm) and short Fibers of Poly (trimetilu00e9n Terephthalate), Yarn and Fabrics.Also a process to make optimal contraction by Curly Short Fibers of Poly (trimetilu00e9n Terephthalate) comprising determining the relationship between the denier and contraction by Curly and making Short Fibers have the denier selected on the basis of this determination.
