PURPOSE:To enhance the abrasion resistance by forming a web composed of a high m.p. fiber or natural fiber and a low m.p. fiber as an upper layer while forming a web composed of a high m.p. fiber reclaimed cotton or natural fiber reclaimed cotton and the low m.p. fiber or a fibrous material as a lower layer to interlace both layers by needle punching and melting the low m.p. fiber or fibrous material to integrate both web layers by pressing. CONSTITUTION:An upper layer web consisting of 60-90wt.% of a high m.p. fiber or natural fiber and 10-40wt.% of a low m.p. fiber and a lower layer web consisting of 40-80wt.% of high m.p. fiber reclaimed cotton or natural fiber reclaimed cotton and 20-60wt.% of the low m.p. fiber or an analogous shape material thereof are laminated to form a laminate wherein the wt. of the lower layer web is 1.5 times or more that of the upper layer web on a wt. basis and this laminate is subjected to needle punching on the surface side thereof to interlace both webs with each other and the low m.p. fiber is melted to integrate and mold both webs by pressing. As the high m.p. fiber, a polyester or polyamide fiber is used and, as the low m.p. fiber, a fiber composed of polypropylene, polyethylene or an ethylene/propylene copolymer can be used. By this method, surface abrasion resistance can be enhanced by compounding and using the low m.p. fiber even in a surface layer. |
