摘要
Problem to be solved: to provide a charge sensitive core structure fiber capable of satisfying heat resistance and charge holding property in an application for an automotive filter.Polypropylene resin is used as the main resin in the sheath and core part.(3) anhydrous carboxylic acid modified polyolefinAntioxidants combined with phenolic antioxidants and phosphorus based antioxidantsOr at least one antioxidant of 0.5 to 3.0 mass% selected from the group consisting of sulfur based antioxidantsContainsOn the outer surface of the sheath(c) an oil containing over 50 mass% of a polyoxyalkylene alkyl ether represented by formula (I) as a finishing oil is applied to the total mass of the sheath core structure fiberA charging sheath core structure fiber characterized by 0.1 to 1.0 mass% adhered.In formula (R1) R1 represents a saturated or unsaturated aliphatic hydrocarbon group of 10 to 30 carbon atoms; R2 represents a hydrogen atom or a methyl group, K is an integer of 1 to 4)No selection
