Apa Itu Benang UHMWPE?
Benang polietilena berberat molekul sangat tinggi (UHMWPE) dibuat dari filamen UHMWPE berkekuatan tinggi. Bahan baku ini biasanya memiliki berat molekul dalam kisaran jutaan gram per mol. Selama proses produksi, polimer umumnya diolah melalui metode pemintalan gel (*gel spinning*) dan peregangan dengan rasio tinggi. Proses ini membantu menyelaraskan rantai molekul sepanjang sumbu serat, sehingga menghasilkan serat yang ringan dengan kekuatan tarik yang tinggi.
UHMWPE plied yarn is made by combining and twisting two or more single yarns. Twisting helps hold the yarn structure together and affects how the yarn performs during weaving, braiding, sewing, and other processing. S-twist or Z-twist can be selected to suit the yarn direction, machine settings, and requirements of the finished product.
UHMWPE yarn has a low density and very low moisture absorption, making it suitable for ropes, fishing nets, cut-resistant textiles, and other industrial products. Its low weight can help reduce the weight of finished products, while its low moisture absorption helps the yarn remain stable in humid conditions. Low moisture absorption does not, by itself, make a fabric or finished product waterproof.
