Thermoplastic polyurethane compound composition for coated yarn and method for manufacturing coated yarn using the thermoplastic polyurethane compound

摘要

The present invention provides a method for manufacturing a coated yarn having outstanding physical properties the method comprising: collecting thermoplastic polyurethane in virgin form as scraps remaining after being suitably used for airbag patterns in a shoe manufacturing process or as 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.
