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: A nonwoven fabric having improved air permeability and strength is formed with a filament of sheath-core shape, the core part being constituted with blending a polyethylene terephthalate (PET) having melting point (Tm) of 250˜270° C. of 40 to 60 parts by weight with a polytrimethylene terephthalate (PTT) having melting point of 215˜235° C. of 10 to 50 parts by weight, the sheath part being constituted with a polyethylene terephthalate (PET) having melting point of 210˜230° C. of 10 to 30 parts by weight, and the core and sheath parts being spun with conjugate respectively, and formed with a web. The bicomponent nonwoven fabric uses a bicomponent polymer and improved spin method with conjugate and blending spinning to produce PTT nonwoven fabric having an improved strength and air permeability and soft property and proper resistance which are required for a variety of uses and to produce it economically.
