(57) [Summary] [PROBLEMS] To provide a heat-bondable fiber which is excellent in process passability in raw cotton and non-woven fabric manufacturing process, has good water repellency and is suitable for non-woven fabric for sanitary material face cover. [Structure] 50 to 50% by weight of a polyolefin-based polymer, 25 to 50% by weight of a silicone-based treating agent on the surface of a heat-adhesive fiber containing a thermoplastic polymer having a melting point of 50 to 200 ° C. as a heat-adhesive component. %, And an oil agent containing 10 to 40% by weight of an amine-based treating agent represented by the following general formula: 0.05 to 5 Wt% (relative to fiber weight) deposited. (However, R is an alkyl group having 8 to 22 carbon atoms, m + n is 5 40 is shown) |
