摘要
There is disclosed fibers and fabrics formed from a polymer which is a "hand enhancing" polymer. The "hand enhancing" polymer is a copolymer of polypropylene which contains ethylene, 1-butene, or 1-hexene or a terpolymer of propylene, ethylene and butene. If the polymer is an ethylene copolymer, the copolymer may be random or random and block and the ethylene must be present in an amount between greater than 5 and 7.5 weight percent of the copolymer. If the copolymer contains 1-butene, it must be present in an amount between 1 and 15.4 weight percent of the copolymer. If the copolymer contains 1-hexene, it must be present in an amount between 2 and 5 weight percent of the copolymer. If the polymer is a terpolymer of propylene, ethylene and butylene, the polypropylene is present in an amount between 90 and 98 weight percent, the ethylene is present in an amount between 1 and 6 weight percent and the butylene is present in an amount between 1 and 6 weight percent. The fibers may additionally have a second polymer adjacent the first polymer in a sheath/core, islands-in-the-sea or side-by-side conjugate orientation.
