Problems solved by technology

[0004] For dark fabrics such as pure cotton, viscose, linen, etc., since most of the reactive dyes dyed dark fabrics have poor wet rubbing fastness, especially some softeners and pre-shrinking after finishing will reduce the wet rubbing fastness. Rubbing fastness, it is difficult to solve the problem of wet rubbing fastness even after repeated repairs

Embodiment 3

[0058] Embodiment three: the multi-functional softener that improves dyeing sublimation fastness and wet rubbing fastness is aimed at the application on the dark pure cotton knitted fabric dyed with reactive dyes:

[0059]First, the dyed dark cotton knitted fabric is subjected to conventional soaping process. After soaping, the liquid is drained. After adding water to the dye tank, 7 g / l natural base is added to improve the sublimation fastness of disperse dyes and the wet rubbing fastness of reactive dyes. Multifunctional Softener, the temperature is controlled at 50 degrees Celsius, and it is treated for 25 minutes. After being dehydrated, it is dried and set. After processing, the wet rubbing fastness can be improved by about 0.5. At the same time, the fabric has a certain anti-shrinkage performance, and the treated fabric feels soft, delicate and elastic.

Abstract

The invention provides a natural multi-functional softener for improving the fastness to sublimation and wet rubbing fastness of dyeing. The natural multi-functional softener is prepared from variouskinds of natural components in a certain weight percentage, and the natural multi-functional softener is suitable for polyester and blended fabrics, pure cotton fabrics, viscose acetal fabrics, linenfabrics, ready-to-wear fabrics and other fabrics dyed with disperse dyes and reactive dyes. In the disperse and reactive dye dyeing and after-finishing treatment process, the softener is added according to a certain weight in use, the fastness to sublimation of the disperse dyes and the fastness to wet rubbing of the reactive dyes can be improved, and moreover, the rate of rework caused by lower fastness to sublimation or wet rubbing fastness is greatly reduced in the after-finishing process, the production efficiency is improved, the energy sources are saved, and elastic and fine handfeelingis given to the fabrics obtained after finishing, the fabrics have excellent stain-resistant, dust-proof, shrink-resistant, anti-pilling and anti-static performance, and the additional value of the fabrics is increased.

Description

technical field [0001] The invention relates to the printing and dyeing industry, in particular to a natural-based multifunctional softener for improving the dyeing sublimation fastness of disperse dyes and the wet rubbing fastness of reactive dyes. [0002] technical background [0003] With the continuous improvement of export textiles and domestic consumers' requirements for the quality and function of textile fabrics, the requirements for fabric sublimation fastness, washing fastness, wet rubbing fastness and other indicators are constantly increasing. For dark polyester blended fabrics, disperse dyes are easy to sublimate after dyeing, so that part of the disperse dyes will be transferred to the surface of the fabric with the high-temperature hot air drying of the setting machine, resulting in a decrease in the washing fastness of the finished product. Most of the treatment methods require rework. After reduction cleaning, low temperature setting. Especially for the fab...
