Abstract: Disclosed is a polyethylene yarn which enables the manufacture of a skin cooling fabric having dimensional stability and having improved weavability which enables the manufacture of a skin cooling fabric capable of providing a user with a soft tactile sensation as well as a cooling sensation, a method for manufacturing the same, and a skin cooling fabric including the same. The polyethylene yarn has a shrinkage stress at 70° C. and 100° C. of 0.005 to 0.075 g/d, respectively. Also, the polyethylene yarn has a “dry thermal shrinkage rate at 70° C.” of 0.1 to 0.5%, a “dry thermal shrinkage rate at 100° C.” of 0.5 to 1.5%, and a “wet thermal shrinkage rate at 100° C.” of 0.1 to 1%.

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.
