Problems solved by technology

At present, the dyeing process after plasma grafting treatment of fabrics is still similar to the conventional dyeing process. Although it can improve the dyeing rate and some other properties of the fabric, it still cannot avoid the production of more pollutants and energy waste in the dyeing and finishing process.
[0004] However, for fibers in the high crystallization region, the dyeing rate is still low after conventional plasma grafting treatment, and the pollution and energy consumption problems are more serious.

Abstract

The invention relates to the field of fabrics dyeing and finishing processes, in particular to a process for dyeing fabrics by combining with plasma and ultrasonic and a special device thereof. The special device comprises low-temperature normal-pressure plasma equipment, grafting reaction equipment, ultrasonic dyeing equipment, a rinsing bath and two groups of control systems, wherein the low-temperature normal-pressure plasma equipment, the grafting reaction equipment, the rinsing bath and the ultrasonic dyeing equipment are sequentially connected, one group of control systems is connected with the low-temperature normal-pressure plasma equipment, and the other group of control systems is connected with the ultrasonic dyeing equipment. The invention organically combines the low-temperature normal-pressure plasma equipment and the ultrasonic dyeing equipment, solves the problem that the dye uptake and the dyeing quality can not improved in a process of dyeing fabrics in a high crystalline region or solves the problem of high energy consumption and high pollution in the dyeing process, and can effectively realize that the dye uptake and the dyeing quality can be improved while realizing environmental-friendly production with low energy consumption and low pollution.

Description

Technical field: [0001] The invention relates to the field of textile dyeing and finishing technology, in particular to a fabric dyeing process using low-temperature atmospheric-pressure plasma combined with ultrasonic treatment, and a special device for fabric dyeing combined with low-temperature atmospheric-pressure plasma combined with ultrasonic treatment. Background technique: [0002] Low-temperature plasma grafting treatment is through plasma treatment of fabrics (mainly referring to fabrics woven with fibers with large crystallization area and low dyeing rate, such as ramie fabrics) in atmospheric pressure air, and the High-energy particles bombard the surface of the fabric, breaking some chemical bonds of the macromolecules on the fabric surface to generate free radicals, introducing some compound monomers to react with free radicals, and realizing a method of grafting certain compound monomers on the macromolecules. [0003] There have been some reports on the rese...
