    摘要： A fiber comprising propylene based polymer composition comprising:
    A) from 90 wt% to 65 wt% of a propylene homopolymer having a Xylene Soluble fraction at 25°C,determined according to ISO 16152: 2005, ranging from 1.5 wt% to 6.0 wt% ;
    B) from 10 wt% to 35 wt% a recycled polypropylene composition being a Post-Industrial Resin (PIR) or Post-Consumer Resin (PCR) ;
    wherein the propylene based polymer composition has a Melt Flow Rate, determined according to the method ISO 1133 (230° C, 2.16 kg), ranging from 15.0 g/10 min to 50.0 g/10 min and a distribution of molecular weight Mw/Mn ranging from 4.5 to 7.5 and the propylene based polymer composition being obtainable with a visbreaking process wherein the visbreaking degree MFRfin/MFRinit is comprised between 3.0 and 10.0 wherein MFRfin is the final Melt Flow Rate of the propylene based composition and MFRinit is the Melt Flow Rate of the propylene based composition before the visbreaking process.

    摘要： This short polypropylene fiber is characterized by: being a short polymer alloy fiber having a sea-island structure in which a polypropylene (A) is a sea component and a thermoplastic resin (B) having a polar functional group is an island component; having, exposed on the surface thereof, the thermoplastic resin (B) that has a polar functional group; and having a fiber length of 20-100 mm and a single fiber fineness of 0.5-3.5 dtex. Provided is a short polypropylene fiber that has improved abrasion resistance while having characteristics of polypropylene, that has excellent texture, and that can be suitably used for a spun yarn.
