HIGH SPEED-SPUN POLYAMIDE MULTIFILAMENT

摘要

PURPOSE:To obtain through a spin-draw process at low lubricant cost without causing the workplace pollution high-strength polyamide multifilament yarns which cause no line shutdown during their weaving in a water jet loom. CONSTITUTION:The objective polyamide multifilament yarns can be obtained by spin-draw process during which the melt-spun polyamide yarns are cooled to solidification followed by imparting the resultant filament yarns with a neat oil containing 5-20wt.% of a sorbitan ester, 1-10wt.% of a POE(1-10) 4-20C higher alcohol phosphate triethanolamine and 0.1-1.0wt.% of an antioxidant.
