Polyethylene yarn containing liquid paraffin
TLDR
In this article, the authors proposed a method to obtain yarn with improved processing properties, frictional resistance, and wear resistance, having a flatness ratio of cross section of yarn of ≥ specific value, a great number of long channels arranged in the fiber axis direction on the surface, containing liquid paraffin having specific characteristics.Abstract:
PURPOSE: The titled yarn useful as a rope, etc., having improved processing properties, frictional resistance, and wear resistance, having a flatness ratio of cross section of yarn of ≥ specific value, a great number of long channels arranged in the fiber axis direction on the surface, containing liquid paraffin having specific characteristics. CONSTITUTION: Liquid paraffin is added to a solution obtained by dissolving ultra-high-molecular-weight polyethylene in decalin, etc., the solution is subjected to solution spinning, and the prepared gel fiber is drawn, to give the desired yarn having ≥1.7 flatness ratio of cross section of yarn, a great number of long channels arranged in the fiber axis direction, a liquid paraffin content (LP) in the yarn of 0.05≤LP≤1.00(wt%), ≥30(g/d) tensile strength, and ≥800(g/d) initial modulus of elasticity.
