Abstract
The present invention provides a coated yarn and a method for manufacturing a coated yarn having outstanding physical properties, the method comprising: collecting thermoplastic polyurethane in virgin form, or from scraps remaining after usage, for example, those used for airbag patterns in a shoe manufacturing process, or from scraps remaining after other thermoplastic polyurethane is processed; mixing the various kinds of thermoplastic polyurethane with various additives; compounding the resultant mixture using an extruder to prepare a thermoplastic polyurethane compound for a coated yarn; and coating the surface of a yarn made from polyester, nylon, spandex, etc. with the compound using an extruder.
Claims2
A coated yarn comprising:
- a yarn core made of polyester, nylon or spandex;
- and
- a thermoplastic polyurethane compound composition coated on the yarn core,
- wherein the thermoplastic polyurethane compound composition comprises thermoplastic polyurethane as a base polymer, a thickener, and a processing aid,
- wherein the thickener is selected from the group consisting of silica, talc, calcium carbonate, and an alloy with a resin selected from a styrene butadiene styrene block copolymer, a styrene ethylene/butylene styrene resin, a polyacetal resin, and a styrene acrylonitrile resin,
- wherein the processing aid is selected from the group consisting of montane wax and fatty acid ester (C5-C9) with pentaerythritol.
