POLYURETHANE UREA ELASTIC FIBER HAVING EXCELLENT LIGHT RESISTANCE AND DYEABILITY AND MANUFACTURING METHOD THEREOF

摘要

PURPOSE: A polyurethane urea elastic fiber which is characterized by increasing operating rate and improving light resistance and dyeability is provided. And a manufacturing method of the fiber is provided. CONSTITUTION: The polyurethane urea elastic fiber is obtained by spinning a polyurethane urea polymer solution. The polyurethane urea polymer solution contains 0.1-2.5wt.% of triazine type compound(formula I) and 0.1-2.5wt.% of triazine type oligomer compound(formula II) containing tertiary amine. In the formula I, R1-R6 are H or C1-C10 alkyl; and R7 is C1-C10 alkyl. In the formula II, R1 is H, C1-C15 alkyl or C1-C15 linear, branch or ring alkyl containing N or O; R2 is C3-C10 alkyl: R3-R12 are H or C1-C4 alkyl; and n is an integer.
