| titleOfInvention | Polyurethane elastic fiber |
| abstract | An object of the present invention is to provide a polyurethane elastic fiber having a high dyeing property and high fastness equivalent to that of a polyamide fiber which is a partner material of a knitted fabric in dyeing with an acid dye, and excellent in spinning stability. is there. The polyurethane elastic fiber of the present invention comprises an isobutylene unit represented by the following formula (I) and the following formula (II) (wherein R 1 represents a linear or branched alkylene group having 2 to 6 carbon atoms, R 2 And R 3 may be the same or different and each represents a straight or branched alkyl group having 1 to 6 carbon atoms) and 0.2 weight of a polymer having a maleimide structure composed of maleimide units % L to 10% by weight and dyed with a specific blue acid dye. The blue L value after washing according to JIS L0844 A2 method is 20 to 50 and the degree of contamination of nylon white cloth is 3.5. It is a polyurethane elastic fiber of grade or higher. |
