摘要：PURPOSE:To obtain the titled structure, capable of providing a soft nonwoven fabric having good feeling and useful as disposable diapers, etc., by melt spinning a linear low-density copolymer of ethylene and octene-1 having a specific density, melt index and heat of fusion and crystalline PP having a specific melt index. CONSTITUTION:The aimed blend structure obtained by blending (A) 99-50wt.% linear low-density polyethylene which is a linear low-density copolymer of ethylene and octene-1, containing 1-15wt.% octene-1 and having 0.900-0.940g/cm<3> density, 25-100g/10min melt flow rate measured by the method of ASTM D-1238 (E) and >=25cal/g heat of fusion with (B) 1-50wt.% crystalline polypropylene having <=20g/10min melt flow rate measured by the method of ASTM D-1238 (L) and melt spinning the resultant blend.
