Title:
A polyethylene tape, polyethylene split yarn, and those manufacturing methods
Document Type and Number:
Japanese Patent JP6060662
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a polyethylene tape and a polyethylene split yarn with smaller change in mechanical property and excellent dimensional stability, capable of selecting a product processing condition in a wide temperature range, and usable in a wide temperature range after product processing.SOLUTION: A polyethylene tape and a polyethylene split yarn comprise polyethylene with a repeating unit being substantially an ethylene chain, in which intrinsic viscosity [η] is 5.0-32.0 dL/g. By TMA (thermomechanical analysis) measurement, maximum heat shrinkage stress is 2.0 cN/dtex or smaller, and thermal shrinkage in a longer direction thereof at 100°C is 5.0% or less.
