    Abstract: 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.

    Abstract: A thermoplastic polyurethane coated yarn having excellent adhesive strength in which hydrophobic nano-silica is mixed. The nano-silica is contained in the range of 0.2-5 parts per hundred resin (phr) and the nano-silica having a primary particle size of in a range of 1-100 nm. The thermoplastic polyurethane coating yarn mixed with the hydrophobic nano-silica of the present invention is uniformly coated with a thermoplastic polyurethane resin containing nano-silica containing a hydrophobic functional group on the surface of the core yarn, whereby the core yarn is biased to one side. Since no coating or uncoating occurs, the product quality and productivity are excellent, in addition to excellent durability and wear resistance of the thermoplastic polyurethane, mechanical strength and chemical resistance are improved.

    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.
