Title:
POLYURETHANE OR POLYURETHANE UREA ELASTIC YARN HAVING IMPROVED DYEABILITY AND PREPARING METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2017/069454
Kind Code:
A1
Abstract:
The present invention relates to a polyurethane or polyurethane urea elastic yarn having improved dyeability and to a preparing method therefor. Here, 0.1-20 wt% of at least one kind of material having an alkaline earth metal element with an electronegativity (Pauling scale) of 1.2 or more, a metalloid element with an electronegativity (Pauling scale) of 1.8 or more, or a post-transition metal element with an electronegativity (Pauling scale) of 1.5 or more is added to a polyurethane or polyurethane urea elastic yarn, and thus, not only can the dyeability of the polyurethane or polyurethane urea elastic yarn in a reactive dye be improved through covalent bonding with the reactive dye, but an advantage of increasing the dyeing color depth in a fabric, in which cotton and the polyurethane or polyurethane urea elastic yarn are knitted together, can also be anticipated.
