Document Type and Number:
WIPO Patent Application WO/2022/262426
Kind Code:
A1
Abstract:
A process for dyeing and finishing a recycled and regenerated high-density cool chinlon fabric. The dyeing and finishing process comprises a pretreatment process, a dyeing process and a setting process, which are carried out sequentially, wherein the pretreatment process comprises a cold pad-batch process and an open-width desizing and washing process; the dyeing process comprises a coloring stage and a moisture absorption and perspiration finishing stage, wherein a dyeing agent used in the coloring stage comprises a dyeing auxiliary agent and a dye; and after the coloring stage is completed, the liquid is drained, and then a moisture absorption and perspiration finishing agent is added for moisture absorption and perspiration finishing, wherein the dyeing auxiliary agent comprises an acidic leveling agent, a chinlon fiber dyeing promoter, a pH slip agent, anti-ultraviolet Rayosan C and anti-ultraviolet DEL; and the moisture absorption and perspiration finishing agent comprises a moisture absorption and perspiration agent and a slip agent VS. By means of formulating a suitable pretreatment process, dyeing process and setting process on the premise of ensuring the dyeing quality and hand feeling of the fabric, the fabric has the functions of breathability, moisture permeability, coolness and ultraviolet resistance, and has new characteristics of being soft, ultra-thin, having a bright color, being fashionable, etc.
