Polyester nonwoven fabric having an improved softness and mechanical property and manufacturing method thereof

摘要

The present invention relates to a polyester-based long-fiber nonwoven fabric having excellent flexibility and mechanical properties and having improved touch feeling, and a method for producing the nonwoven fabric. The present invention relates to a polyester- (HDPE) having a melt index (MFR) of 10 to 25 g / 10 min and a density of 0.950 to 0.9566 g / cm ³ at 190 DEG C, the polyester sheath non- (PTT) having a viscosity of 0.8 to 1.2 cps or polyethylene terephthalate (PET) having a viscosity of 0.6 to 0.8 cps is mixed with the core, And the fibers spun using a circular nip is thermally bonded by an embossing roll. The polyester-based long-fiber nonwoven fabric having excellent flexibility and mechanical properties of the present invention having the above-described structure and having improved tactile sensation can be obtained by using conventional polypropylene (PP) alone or polyethylene-polypropylene (PE-PP) Heat-fusion process is possible because the tensile strength is high and the melting point difference of the material of the binary is high. In addition, it is flexible in comparison with a product made of PET or PET type core-sheath type, and is very soft in surface, which is suitable for applications where contact with the skin or frequent deformation is frequent, and furthermore, compared with conventional PE- By adding PTT component, it is possible to exhibit improved flexibility while having high tensile strength, and it is possible to improve pyrolysis, suppression of fume generation, and operation at high temperature conditions for radiating PET fiber by applying HDPE.
