Abstract
The thermoplastic polyurethane yarn of the present invention is excellent in abrasion resistance and durability because it contains thermoplastic polyurethane and nanosilica particles having hydrophobic functional groups on the surface thereof and is excellent in durability of a fine denier yarn, and can have a yarn in a form of continuous yarn without breaking yarn development during spinning or stretching. In particular, it is excellent in color dispersibility, antifouling property, scratch resistance, moldability, and the like.
Claims17
A thermoplastic polyurethane yarn comprising a thermoplastic polyurethane composition,
- wherein the thermoplastic polyurethane composition comprises nanosilica particles having a primary particle size of 1 to 100 nm and 0.5 to 7.0 parts per hundred resin (phr) based on a thermoplastic polyurethane;
- wherein the nanosilica particle comprises a hydrophobic functional group on the surface thereof and the nanosilica particles form aggregates of nanosilica particles,
- wherein the nanosilica aggregates have size of 100 to 1200 nm.
