Abstract: A nonwoven fabric having improved air permeability and manufacturing method thereof are presented. The nonwoven fabric has improved air permeability and is formed with long fiber nonwoven fabric of single or multi layer, wherein the long fiber nonwoven fabric is produced by spinning polytrimethylene terephthalate having viscosity of 0.8 to 1.2 and polyethylene terephthalate having viscosity of 0.6 to 0.8 to sheath/core shape with using each spinneret pack which can spin filaments having different denier from each other and arranged in parallel with each other, and then heat pressing with free-embossing or embossing pattern to bind the filaments.The nonwoven fabric has excellent air permeability, softness and resistance, which are required for nonwoven fabric sheets used for various purposes as well as their economical production.

Abstract translation: 本发明提供一种具有改善透气性的无纺布及其制造方法。 无纺布的透气性提高，由单层或多层长纤维无纺布形成，长纤维无纺布是通过将粘度为0.8〜1.2的聚对苯二甲酸乙二醇酯和粘度为0.6〜0.8的聚对苯二甲酸乙二醇酯进行纺丝而成的 /芯形，使用每个喷丝头组件，其可以将具有不同旦数的细丝彼此旋转并彼此平行布置，然后用自由压花或压花图案热压以结合长丝。 该非织造织物具有优异的透气性，柔软性和耐性，这是用于各种目的的无纺布片以及其经济生产所必需的。
