Polyurethane urea elastic yarn with improved dyeability and its manufacturing method |
| abstract |
【Task】 An object of the present invention is to provide a polyurethane urea elastic yarn having improved dyeability against acid dyes and a method for producing the same. SOLUTION: During the production of polyurethane urea elastic yarn, the hydrophilicity of polyurethane urea elastic yarn is improved through the process of mixing polyethylene glycol with polyol and then adding diisocyanate to prepare the prepolymer in the prepolymer production stage. Not only can the accessibility of the acidic dye be improved to improve the dyeability of the polyurethane urea elastic yarn, but also the advantage of deepening the dyeing of the woven fabric in which nylon and the polyurethane urea elastic yarn are knitted together can be expected. |
