NONWOVEN FABRIC COMPOSED OF HEAT-BONDING CONJUGATE FIBER

摘要

PURPOSE:To obtain the subject nonwoven fabric having soft feeling by thermocompression bonding spun-bonded nonwoven fabric of hot-adhering conjugate fiber composed of linear low density polyethylene as sheath component and polyamide as core component. CONSTITUTION:Spun-bonded nonwoven fabric made of hot-adhering conjugate fiber having <=5 denier single fiber size composed of linear low density polyethylene (1-15wt.% octene-1 content) having 0.900-0.940g/cm<3> density, 5-45g/10min MI value, >=25cal/g heat of fusion as sheath component and polyamide as core component is subjected to thermocompression bonding at a temperature of 15-30 deg.C lower than melting point of the sheath component to afford the aimed nonwoven fabric having 7-40% pressure contact area fraction and 10-200g/m<2> weight per unit area.
