Abstract:
A thermally welded manufactured article prepared from thermoweldable polyolefin fibers comprising an olefin crystalline polymer containing as stabilizer(s), based on the total weight of the olefin crystalline polymer and stabilizer(s)a) from 0.01 to 0.5% by weight of at least one member of the group consisting of organic phosphites and phosphonites; b) from 0.005 to 0.5% by weight of one or more HALS; wherein any phenolic antioxidant is either absent or present in concentration not greater than 0.02% by weight; the thermowelding being performed by operating at a temperature lower than a melt temperature of the polyolefin constituting the fibers.
