  • Process for spinning thermoweldable fibers obtained from polyolefin composition
    Patent number: 6677039
    Abstract: Crystalline olefin polymers in the form of granules or nonextruded particles having regular geometric form, containing one or more of the following stabilizers: a) from 0.01 to 0.5% by weight of one or more organic phosphites or phosphonites or mixtures thereof; or b) from 0.005 to 0.5% by weight of one or more HALS (Hindered Amine Light Stabilizer); or c) mixtures of (a) and (b); and optionally one or more phenolic antioxidants at a concentration not higher than 0.02% by weight. The fibers obtained from said polyolefins have high thermoweldability and good resistance to yellowing and aging.
