Graduell duft-abgebende Textilien

摘要

A gradual fragrance-emitting textile material contains at least 10% by weight of fragrant non-hollow core-in-sheath type composite staple fibers having a length of from 3 mm to 150 mm and comprising: (1) a non hollow core portion comprising (i) 0.1 to 5% of an essential oil and (ii) the balance consisting of an olefin polymer composition; and (2) a sheath portion covering the core portion and comprising a polyester resin, the olefin polymer composition (ii) comprising: (A) 50 to 98% by weight of an olefin polymer which is a polymerization product of at least one member selected from ethylene and alpha -olefins, and free from polar radicals; and (B) 2 to 50% by weight of a modified olefin polymer which is a copolymerization product of (a) 70 to 97% by weight of at least one olefin with (b) 3 to 30% by weight of at least one ethylenically unsaturated polar monomer selected from ethylenically unsaturated carboxylic acids, ethylenically unsaturated alcohols, ethylenically unsaturated esters and anhydrides and amides of the above-mentioned carboxylic acids, and uniformly blended with the olefin polymer (A).
