Embodiment 1

[0018] A washing process for cashmere fabric after dyeing, comprising the following steps:

[0019] (1) Bake the dyed cashmere fabric in a dry environment at 80°C until the moisture content in the cashmere fabric reaches 30%;

[0020] (2) The baked cashmere fabric is fixed by steaming process; the temperature of the steam is 300°C, and the working time is 10 minutes;

[0021] (3) Place the cashmere fabric treated in step (2) in a washing machine filled with water at 30°C and whose volume is 10 times that of the cashmere fabric, and rotate and wash it for 7 minutes;

[0022] (4) After cleaning, drain the water, and inject hot water at a temperature of 60°C into the washing machine at the same time, and perform rotating cleaning again. The working time is 8 minutes;

[0023] (5) After cleaning, dehydrate and dry the cashmere fabric, put it in a bucket filled with cold water at 20°C and 5 times the volume of the cashmere fabric, and at the same time put 300g of color-fixing alka...

Abstract

The invention discloses a water washing technology of a dyed fleece fabric. The water washing technology comprises the technological processes of steaming for color fixation, gradual warming type water washing, and alkali salt color fixation. The process of steaming is capable of remarkably improving the low coloring rate of the dyed fleece fabric; meanwhile, the dry and wet crocking fastness of the fleece fabric is enhanced via step-by-step gradual warming type water washing, so that the fleece fabric does not fade easily in use; finally, alkali salt is utilized for color fixation to improve the color yield of the fleece fabric. Therefore, the dyed fabric is fresh and engaging in color.

Description

technical field [0001] The invention relates to a fabric processing method, in particular to a washing process for dyed cashmere fabric. Background technique [0002] Reactive dyes are composed of parent dyes, linking groups and active groups, so that they can form a strong covalent bond with the fiber when used, and have a series of characteristics that other cellulose fiber dyes cannot match, and establish it as a fiber dye. The development and use of dyes for plain fibers is the key position; cashmere fabrics have the defects of low dyeing absorption rate, coloring rate and low fastness after dyeing with reactive dyes due to the characteristics of easy brushing of cashmere fabrics; washing after dyeing with reactive dyes The water process is actually a very important step. At present, many manufacturers have not paid attention to it, and have not formulated a suitable and effective washing process. In fact, a suitable washing process can solve some sequelae of reactive dy...
