Problems solved by technology

[0002] Nylon-polyester fabric is a kind of metal wire fabric, usually made of 88% polyester yarn, 9% nylon yarn, and 3% spandex yarn. Nylon-polyester fabric combines the characteristics of nylon and polyester, which is soft and drapable. Well, like the metal wire fabric, the surface has a metallic luster, faintly flickering, and changes with the change of the light source. The nylon-polyester fabric products that are currently available in the market often fade to varying degrees during the washing process. After a long period of use, dull color, yellowing, and fading will also appear. Therefore, it is of great market value to provide a dyeing and finishing process with high color fastness for nylon and polyester fabrics.

Abstract

The invention provides a high color fastness dyeing and finishing process for a polyamide polyester fabric. Dyeing and finishing are carried out through desizing, dyeing, color fasting and aftertreatment processes, the dyeing and finishing process is simple and rapid and convenient to operate, a dyed polyamide polyester fabric is uniform in color, natural in color and soft and fine in fabric, various color fastness grades after dyeing are all greater than 4, that is, the color fastness grade is far greater than those of common polyamide polyester fabrics in the market, and the fabrics are high-quality polyamide polyester fabrics.

Description

Technical field [0001] The invention belongs to the technical field of fabric dyeing and finishing, and specifically relates to a process for dyeing and finishing nylon-polyester fabrics with high color fastness. Background technique [0002] Nylon-polyester fabric is a kind of metal wire fabric, usually composed of 88% polyester yarn, 9% nylon yarn, and 3% spandex yarn. Nylon-polyester fabric combines the characteristics of nylon and polyester, with soft hand feeling and drape Well, like the metal wire fabric, the surface has a metallic luster, faintly shimmering, and changes with the change of the light source. Nowadays, the products of nylon-polyester fabrics on the market often fade in different degrees during the washing process. After a long time of use, there will be dull color, yellowing, and fading. Therefore, providing a dyeing and finishing process with high color fastness for nylon-polyester fabric has a greater market value. Summary of the invention [0003] Based on...
