Abstract

The invention discloses a processing method for improving the soaping resistance fading fastness of yarn dyed fabrics and the yarn dyed fabrics. The method comprises the steps that silicon dioxide hydrosol is prepared through water glass; the silicon dioxide hydrosol is adopted for padding the yarn dyed fabrics, and then drying is conducted; hexadecyltrimethoxysilane hydrolysate is prepared; sodium hypophosphite is added into the hexadecyltrimethoxysilane hydrolysate, then the yarn dyed fabrics obtained through the silicon dioxide hydrosol processing is subjected to padding again, and drying and baking are conducted. According to the processing method, raw materials are easy to obtain, the price is low, safety and environmental protection are achieved, the process is simple, and the soaping resistance fading fastness of chemosynthetic dye yarn dyed fabrics and natural dye yarn dyed fabrics is improved.

Description

technical field [0001] The invention belongs to the field of textile processing, and in particular relates to a treatment method for improving the soaping and fading fastness of dye dyeing and yarn-dyed fabrics. Background technique [0002] With the improvement of people's living standards, the quality requirements of textiles are also getting higher and higher, and the pursuit of comfort, nature and health care. In recent years, Germany and other European and American countries have successively formulated a series of ecological textile standards. Color fastness is an important indicator for evaluating the quality of textile dyeing, and it is also an important factor for reducing wastewater pollution. In particular, due to the high attention paid to the hazards of synthetic banned dyes at home and abroad, in order to protect public health and environmental safety, research on the dyeing of textiles with natural dyes derived from plants is active. But at present, the bigg...
