Functional polyolefin staple fiber and method for fabricating the same and thermal bonding non-woven using thereof

摘要

The present invention is a method for producing a polyolefin short fiber, melting the polyolefin resin; Spinning the melt at a rate of about 30-50 m / min at a spinning temperature of about 250 ° C .; Stretching the spun yarn at a draw ratio of 1.5 to 2.0 and a preheating temperature of 50 to 80 ° C; Crimping to impart crimp to the stretched filaments; A surface treatment step of fusing the crimped filament by spraying a liquid resin containing a functional spinning oil and a green tea extract mixture; And it provides a method for producing a functional polyolefin-based short fibers comprising the short-fiber forming step of cutting the surface-treated filament heat cut after a predetermined length.; Antibacterial, Deodorant, Polyolefin
