| titleOfInvention | Polypropylene composite fiber |
| abstract | PROBLEM TO BE SOLVED: To provide a catalyst for polyolefin production with a small amount of book (co) A polypropylene composition having a high melt tension obtained by subjecting propylene to main (co) polymerization using a catalyst pre-activated by supporting polypropylene for polymerization and polyethylene having a specific intrinsic viscosity is used as a sheath component of the composite fiber. This provides a polypropylene-based composite fiber useful as a nonwoven fabric material having excellent tensile strength and heat sealability. SOLUTION: 0.01 to 5 parts by weight of a polyethylene having an intrinsic viscosity [ηE] of 15 to 100 dl / g measured in tetralin at 135 ° C, and 0.01 to 20% by weight of an α-olefin other than propylene. A composition comprising 100 parts by weight of a propylene-α-olefin copolymer (intrinsic viscosity measured at 135 ° C. in tetralin: 0.2-2.5 dl / g, melting point: 110-150) ° C) as a sheath component, crystalline polypropylene as a core component, and composite (sheath component / core component) = 20 / 80-60 / 4 Set to 0. |
