ARTIFICIAL LEATHER FOR UPPER LEATHER OF GOLF SHOES

摘要

PURPOSE: Artificial leather for the upper leather of golf shoes is characterized by having excellent shape stability, fullness, flexibility, crease property and wearing feeling. CONSTITUTION: Artificial leather comprising superfine fiber and a polyurethane elastomer is obtained by the steps of: preparing binary conjugate staple fiber for superfine yarn comprising nylon and copolymerized polyester; preparing 20-80wt.% of nylon staple fiber; mixing the binary conjugate staple fiber and the nylon staple fiber in a ratio of 50:50, followed by opening and carding; needle-punching to manufacture non-woven fabric; padding into 10% of a caustic soda aqueous solution, followed by squeezing; eluting a sea ingredient; washing and drying; padding a polyvinyl alcohol aqueous solution on the non-woven fabric, followed by drying; infiltrating the polyurethane elastomer into the non-woven fabric sheet; and then buffing with a sand paper. The polyurethane elastomer has 120-130kg/cm¬2 of modulus for 100% of elongation.
