Problems solved by technology

However, high-temperature dyeing not only consumes a lot of energy and increases the cost of dyeing, but also under high-temperature dyeing conditions, the natural style of wool is easily damaged by the action of heating and chemical reagents, such as lower color brilliance, hard feel, strong Decrease, decrease in resilience, not conducive to the processing of the next process, affect its aesthetic value, decline in wearing performance, decline in market competitiveness, etc.
Based on the above reasons, many environmentally friendl

Abstract

The invention discloses an efficient dyeing process for improving the anti-felting performance of wool fabric. The method includes the following steps that 1), the wool fabric is added into a nano titanium dioxide water solution to vibrate under ultrasonic waves and then dried; 2), after the wool fabric and cationic ceratin graft polymer powder are mixed, the mixture is treated with a negative pressure-positive pressure interaction method under high-speed stirring; 3), the wool fabric is subjected to ultrasonic treatment in the wet air environment; 4), the wool fabric is heated and dyed; 5), the dyed wool fabric is treated with a high-pressure treatment-pressure relief treatment interaction method and then washed and dried. According to the dyeing method, the wool fabric is subjected to aseries of pretreatment, it is promoted that dye seeps into wool fibers, and thus, the dyeing degree of the wool fabric is improved. By means of the method, scale layers of the wool fibers cannot be damaged, and the dyed wool fabric has good anti-felting performance and the capacity of resisting the external physical and chemical effect.

Description

technical field [0001] The invention belongs to the technical field of clothing fabric processing, and in particular relates to a high-efficiency dyeing process for improving the anti-felting performance of wool fabrics. Background technique [0002] Wool is an important natural fiber, which is widely used in high-grade textile fabrics due to its excellent hygroscopicity, resilience, hand feeling and wearing comfort. Wool fiber is composed of some tiny single cells. Due to the difference in size, shape, nature, arrangement and function of these cells, wool can be divided into three layers, namely scale layer, cortex layer and pith layer. Because the surface of wool is covered with scales, it is relatively hard and has a stronger ability to resist external physical and chemical effects. It has a shielding effect on the penetration of dyes, making it difficult for dyes to penetrate into the inner layer of wool. Therefore, wool is generally dyed at high temperature. However, h...
