Title:
RESIN FOR THERMOPLASTIC POLYURETHANE YARN USING NANO-SILICA, AND METHOD FOR MANUFACTURING THERMOPLASTIC POLYURETHANE YARN BY USING SAME
Document Type and Number:
WIPO Patent Application WO/2018/164433
Kind Code:
A1
Abstract:
The present invention relates to: a resin for a thermoplastic polyurethane (TPU) yarn using nano-silica, the resin allowing a TPU yarn to be continuously drawn out without being cut while ensuring desired processability and physical properties by mixing nano-silica having a particle size of 100 nm or less as a thickening agent for improving productivity and a quenching property when manufacturing a thin monofilament or multifilament yarn, such as a monofilament yarn of 50-350 denier or a multifilament yarn of 50 denier or less, from a TPU alone without coating a TPU on the surface of a polyester or nylon yarn as was done in the prior application invention described above when manufacturing a TPU yarn (preferably, when manufacturing a TPU-only monofilament yarn or a TPU-only multifilament yarn); and a method for manufacturing a TPU yarn by using the same.
