TH31392A - Branched polyesters and copolyesters form long fibers. - Google Patents

Abstract

DC60 (25/05/41) polyester and copolymer ester Branched to form long fibers with a relative molecular weight greater than 10,000 are supplied, obtained by condensing in the precursor components of 50-500 ppm polyester to form. Of substances that make branches into one kind Or more that fills during Produced by polyester machines. And there is a general formula HO (chemical formula) where n = 2-4 it would be perfectly suitable. For high-speed spinning of industrial textiles and yarns that It has a wind speed of 2,500-10,000 m / min, followed by a traditional dragging. Or the process of texturing, zinc, polyester and copolymer esters That have branched into a long web form With a relative molecular weight of> 10,000 is supplied, obtained by condensing In the starting element Of the form is 50-500 ppm polyester of one or more branching agents added during the Produced by polyester machines. And there is a general formula HO (chemical formula) where n = 2-4 it would be perfectly suitable. For high speed spinning of textiles And industrial threads that It has a wind speed of 2,500-10,000 m / min, followed by a traditional dragging. Or the process of texturing it. Zinc

Claims (2)

1.Polyesters and colosters The branched strands form long fibers with a relative molecular weight of> 10,000, which contain very small amounts of branched substances and are obtained by condensation.
