摘要： 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.

摘要： 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%.

摘要： Disclosed is a method for manufacturing a polyester fabric for an airbag that can not only prevent or minimize the separation of a sizing agent, which is provided to a yarn through a sizing process, during a weaving process, but can also maximize a peel strength between a textile substrate and a coating layer to be subsequently formed thereon and lower the stiffness of an airbag fabric by effectively removing the sizing agent from the textile substrate after the weaving process is completed. The method of the present invention comprises: applying a polyester-based sizing agent to a polyester yarn; manufacturing a textile substrate with the sizing agent-applied polyester yarn; removing the sizing agent from the textile substrate under an alkaline condition of pH 8 to 10; and forming a coating layer on the sizing agent-removed textile substrate in order to enhance air-tightness.
