  • Patent number: 11286586
    Abstract: The present invention provides a resin for thermoplastic polyurethane (TPU) yarn using nanosilica and a method for manufacturing the same. Nanosilica having a particle size of 100 nm or less is added as a thickening agent for improving productivity and glossiness of 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. No TPU coating is needed for applying to the surface of polyester or nylon yarns, thereby securing desired workability and properties and realizing continuous drawing of TPU yarns without thread breakage. The content of nanosilica at least from 0.1 or 0.3 to 7 phr, or a non-zero content of 7 phr or less in TPU resin is optimal for productivity of mono- or multi-filament yarns. The content of nanosilica from 0.5 to 1.5 phr is optimum for both productivity and cost reduction.
