METHOD FOR PRODUCING FIBERS HAVING A LOW SURFACE ENERGY AND FIBERS, YARNS AND TEXTILES HAVING A LOW SURFACE ENERGY

摘要

The present invention relates to a method for producing a low surface energy fiber having a long-term liquid repellency and anti-stain effect.;The present invention relates to an addition of a specific ratio of low surface energy additives to a thermoplastic polymer used as a spinning raw material, which is subjected to spinning processing procedure, such as melting spinning, to produce fibers with a surface tension of between 25˜72 dyne/cm.

1. A method for producing fibers having a low surface energy comprising
step (i): formulating a thermoplastic polymer containing 0.1 wt %˜30 wt % of a low surface energy additive; and one of the following steps: step (ii-a): subjecting the thermoplastic polymer as a spinning raw material to conduct melt spinning, followed by drawing and false twist processing to produce fibers with a surface tension of between 25˜72 dyne/cm; step (ii-b): subjecting the thermoplastic polymer as a spinning raw material to conduct melt spinning, drawing and setting to produce a fully drawn yarn (FDY) with a surface tension of between 25˜72 dyne/cm; or step (ii-c): subjecting the thermoplastic polymer as a spinning raw material to conduct melt spinning, multi-stage drawing and setting to produce a high tenacity yarn (HTY) with a surface tension of between 25˜72 dyne/cm.
