Abstract
This invention relates to multi-component fibers made of at least 40 weight percent, and preferably over 50 weight percent of one or more high chain length polyamides. The fibers have both a high tear strength and good tensile strength. The fibers can be used to produce woven and non-woven articles having excellent toughness.
Claims16
A tough multi-component fiber comprising:
- a) 40 weight percent or greater of one or more high chain-length polyamides having a polyamide chain length of greater than 6;
- and
- b) less than 60 weight percent of one or more other thermoplastic polymers having a melting point lower than that of said high chain-length polyamides.
