Abstract:
The present invention can provide a chargeable core/sheath-structured fiber that can exhibit a satisfactory heat resistance and a satisfactory charge retention behavior. The chargeable core/sheath-structured fiber uses a polypropylene-type resin as its main resin, and in the sheath section contains (a) a carboxylic acid anhydride-modified polyolefin and (b) at least one antioxidant selected from the group consisting of sulfur-type antioxidants, or antioxidants that combine a phenolic antioxidant and a phosphorus-type antioxidant. There is adhered to the outer circumference of the sheath section (c) an oil agent containing a polyoxyalkylene alkyl ether represented by general formula (I) and functioning as a finishing oil. (In the formula, R1 represents a C10-30 saturated or unsaturated aliphatic hydrocarbon group. R2 represents a hydrogen atom or methyl group, and k is an integer from 1-4.)
