RESIN FOR THERMOPLASTIC POLYURETHANE YARN USING NANOSILICA AND METHOD FOR-MANUFACTURING THERMOPLASTIC POLYURETHANE YARN USING THE SAME

The present invention provides a resin for thermoplastic polyurethane (TPU) yarn using nanosilica and a method for manufacturing a thermoplastic polyurethane yarn using the same, where nanosilica having a particle size of 100 nm or less is added as a thickening agent for improving productivity and glossiness in the production of thermoplastic polyurethane yarns (preferably, mono- or multi-filament yarns using TPU alone), specifically in the production of thin TPU yarns, such as mono-filament TPU yarns having a denier count of 50 to 350 or multi-filament TPU yarns having a denier count of 50 or less without applying a coating of TPU to the surface of polyester or nylon yarns as disclosed in the prior art, thereby securing desired workability and properties and realizing continuous drawing of TPU yarns without thread breakage.
