Abstract: Disclosed is a high strength polyester fiber for a seat belt, and in particular, a polyester fiber for a seat belt, which has intrinsic viscosity of 0.8 to 1.5 dl/g, tensile strength of 8.8 g/d or more, and total fineness of 400 to 1800 denier. A method of preparing the fiber is disclosed. The polyester fiber includes filaments having high strength, low modulus, and high elongation to significantly lower shrinkage, while securing excellent mechanical properties, it is possible to manufacture a seat belt having excellent impact absorption and significantly improved abrasion resistance and heat resistant strength retention, even with a woven density of 260 yarns/inch or less.

Abstract: Disclosed is a polyethylene yarn capable of providing a user with a soft tactile sensation as well as a cooling feeling or a cooling sensation, and also having improved weavability that enables the manufacture of a skin cooling fabrics having excellent pilling resistance, abrasion resistance, cuttability, and sewability, a method for manufacturing the same, and a skin cooling fabric including the same. In a strength-elongation curve of the polyethylene yarn obtained by measuring at ambient temperature, (i) elongation at strength of 1 g/d is 0.5 to 3%, (ii) elongation at strength of 3 g/d is 5.5 to 10%, and (iii) a difference between elongation at strength of 4 g/d and elongation at maximum strength is 5.5 to 25%, and the polyethylene yarn has toughness of 55 to 120 J/m3 at ambient temperature.
