FIBER FORMED FROM PROPYLENE-BASED COPOLYMER OR COMPOSITION THEREOF, AND TEXTILE PRODUCT THEREOF

摘要

PROBLEM TO BE SOLVED: To provide a propylene-based fiber material and textile products thereof, which are excellent in dyeability and hydrophilicity, causes no degradation of inherent performance of polypropylene, such as rigidity and heat resistance. SOLUTION: The fiber formed from a propylene-based copolymer or composition thereof, is compounded with 100-30 wt.% polar group-containing propylene copolymer (A) which includes 94.9-99.99 mol% propylene unit represented by structural formula (I), 0.01-0.1 mol% polar unit represented by structural formula (II) and 0-5 mol% nonpolar unit represented by structural formula (III), and has 20,000-1,000,000 weight-average molecular weight, 0-50 wt.% propylene-based polymer (B) and 0-20 wt.% thermoplastic resin (C) other than the polypropylene-based polymer, wherein MFR of the mixture of the ingredient (A), the ingredient (B) and the ingredient(C) is 1-3,000 g/10 min (wherein, R1is a 1-20C hydrocarbon containing a polar group; and R2is H or a 2-20C hydrocarbon).
