摘要： Polyolefin fibers are disclosed having a surface portion of a low-orientation domain and an inner portion of a high-orientation domain, the orientation parameter, as measured by the Raman spectroscopy, of the low orientation domain is smaller than that of the high orientation domain by 2.2 or more, but less than 8.0. By using the polyolefin fibers, non-woven fabrics having a high strength and excellent hand feeling can be provided. Further, since the fibers can be processed into nonwoven fabrics at a wide range of processing temperature when a point bonding method is used, non-woven fabrics having stabilized qualities can be prepared.

摘要： The present invention is directed to a resin composition for electric insulation materials for vehicles such as distributor caps which is prepared by blending a crystalline propylene-ethylene copolymer resin with 3 to 10 wt. % of a glass fiber, 10 to 20 wt. % of talc or mica, 5 to 20 wt. % of silica, 4 to 20 wt. % of modified polyolefin resins, 10 to 30 wt. % of halogen-containing flame retardants and 3 to 15 wt. % of flame retardant auxiliaries. In the resin composition of the present invention, balance is kept in all points of mechanical characteristics, mechanical characteristics at high temperature, electrical characteristics, nitric acid resistance, weld characteristics, blooming resistance, corona resistance and flame retardance.
