Polyolefin composition containing low viscosity propylene homopolymer, fiber and extensible non-woven fabric prepared therefrom |
摘要 |
A polyolefin composition which contains 45 to 5 weight percent of a low viscosity propylene homopolymer having an as polymerized melt flow rate of 250 to 550 g/10 minutes and 55 to 95 weight percent of an olefin polymer composition, preferably a random copolymer of propylene and ethylene and/or a C4-10 alpha-olefin or mixtures thereof, containing from 90 to 99 weight percent propylene. The composition may be formed into fibers having a diameter of from 15 to 23 microns. The fibers may be used to produce nonwoven fabrics.
