Problems solved by technology

However, the current dyeing of natural dyes has low color fastness, especially the low color fastness to washing and weather resistance; especially when it is applied to the dyeing of mixed fabrics, the dyeing color difference of the fabric is very large, and the color fastness is very low , so natural dyes are rarely used in industrial production to dye mixed fabrics
[0005] In view of the above-mentioned related technologies, the inventor believes that there are defects such as large color difference and low color fastness when mixed fabrics are dyed with natural dyes, so it is necessary to develop a new dyeing method for mixed fabrics

Abstract

The invention relates to a dyeing process of a blended fabric. The dyeing process sequentially comprises the following steps of pretreatment, dyeing, water washing and soaping, modification treatment and sizing. According to the method, the hydrophilicity and the bulkiness of the fabric can be improved through plasma treatment and ultrasonic treatment, so that the fabric can react with dye more easily, the blended fabric is dyed, and the dyeing uniformity and the color fastness are improved. After dyeing, water washing and soaping are completed, the blended fabric is further subjected to silicate ester modification, Si-O bonds can be generated on the fiber surface through silicate ester modification to form a three-dimensional network film, the dyeing color fastness can be further improved, and the hydrophilicity of the blended fabric is further improved. The natural plant dye is adopted to dye the blended fabric, and the natural plant dye has degradability, so that the dyeing method is healthier and more environmentally friendly.

Description

technical field [0001] The present application relates to the technical field of fabric dyeing process, in particular to a dyeing process for blended fabrics. Background technique [0002] Blended fabrics refer to textile products woven from a variety of fiber blended yarns. Blended fabrics can fully combine the advantages of various fabrics, so that the fabrics have better skin-friendly, elastic or mechanical strength and other properties to meet various usage scenarios. For example, polyester-cotton blends are textiles made of polyester as the main component and woven with 65-67% polyester and 33-35% cotton blended yarns; its characteristics are that it not only highlights the style of polyester but also the advantages of cotton fabrics, It has good elasticity and wear resistance in dry and wet conditions, stable size, small shrinkage, and has the characteristics of straightness, not easy to wrinkle, easy to wash, and quick-drying. Soak in boiling water. [0003] There ...
