PROCESS FOR PREPARING POLYOLEFINS PROPERTY FOR FIACAO, OF THERMAL-SOLDABLE FIBERS, OF THERMALLY SOLVED AND TEXTILE ARTICLES FORMED THEREOF

摘要

Crystalline polymers of olefins in the form of granules or nonextruded particles having regular geometric form, containing one of more of the following stabilizers: a) from 0.01 to 0.5% by weight of one or more organic phosphites and/or phosphonites; b) from 0.005 to 0.5% by weight of one or more HALS (Hindered Amine Light Stabilizer); and optionally one or more phenolic antioxidants in concentration not higher than 0.02% by weight. The fibers obtained from said polyolefins have high thermoweldability and good resistance to yellowing and aging.
