PURPOSE:To obtain the subject short fiber having a specific length, emitting lasting fragrance and useful for beddings, pillow, cushion, etc., by using a specific olefinic polymer composition containing a small amount of an essential oil as a core part and a polyester as a sheath part. CONSTITUTION:The objective fiber is a sheath-core conjugate short fiber having a fiber length of 30-100mm and composed of a core part containing 0.1-5wt.% (preferably 0.5-2wt.%) of an essential oil and consisting of an olefinic polymer composition composed of (A) 98-50wt.% (preferably 98-70wt.%) of an olefin polymer composed essentially of an alpha-olefin and free from polar group and (B) 2-50wt.% of a modified olefinic polymer copolymerized with 3-30wt.% (preferably 5-20wt.%) of one or more components selected from unsaturated carboxylic acid, unsaturated alcohol, their ester, acid anhydride and amide and a sheath part consisting of a polyester. |
