Multi-material combined fiber fabric color-mixing-free printing and dyeing process

Abstract

The invention discloses a color-mixing-free printing and dyeing process for a multi-material combined fiber fabric, relates to a printing and dyeing processing technology, and aims to solve the problems that multiple dyed fabrics are dyed basically through multiple times of dyeing and matching of different dyes, and the same fabric comprises different material areas, so that the color-mixing-free printing and dyeing process cannot be realized. The technical scheme is characterized in that the method comprises the following steps: step 1, preparing a waterproof coating and the fabric to be dyed; step 2, sizing the fabric outside one area needing to be dyed, and drying and dewatering to complete primary film covering; 3, the fabric is put into an overflow dyeing machine to be dyed, and color fixation is carried out. In the multi-time dyeing process, the problems of shading and color mixing can be avoided, the situation that fabric is scrapped and dye is scrapped is avoided, the printing and dyeing frequency is reduced, the rate of finished products is increased, and the good energy-saving and environment-friendly effects are achieved.

Description

technical field [0001] The invention relates to printing and dyeing processing technology, more specifically, it relates to a multi-material combined fiber fabric non-mixing color printing and dyeing process. Background technique [0002] Printing and dyeing, also known as dyeing and finishing, is a processing method and a general term for pretreatment, dyeing, printing, finishing, washing, etc. [0003] At present, the prosperity of the textile industry in Zhejiang and Jiangsu is accompanied by the rise of the textile printing and dyeing industry. The printing and dyeing of fabric colors always runs through the production of fabrics. As the demand for fabrics in the society gradually increases, different fabrics on the same piece of fabric The color value has also increased.

[0003] At present, the prosperity of the textile industry in Zhejiang and Jiangsu is accompanied by the rise of the textile printing and dyeing industry. The printing and dyeing of fabric colors always runs through the production of fabrics. As the demand for fabrics in the society gradually increases, different fabrics on the same piece of fabric The color value has also increased. The current dyeing process is basically through multiple dyeing, through the combination of different dyes, and finally dyes a variety of dyed fabrics. There are also areas of different materials on the same fabric, which makes even It is necessary to keep the fabric in a uniform color, and it is impossible to finish the dyeing work with one dye and a single dyeing, which is a waste of water and dye resources
