Embodiment

[0018] (a) Preparation of dyeing solution: prepare a dyeing solution of 65g / L sodium silicate, 13.8g / L caustic soda, and 20g / L dyestuff, and control the temperature of mixed lye and dyeing solution within 25°C;

[0019] (b) Rolling material: for fabric dyeing, adjust the roller pressure of the padding car to the minimum, the oil pressure in the middle is 1.8kg, the air pressure on both sides is 1.2kg, the speed of the machine is 40m / min, and the rolling rate is guaranteed to be above 65%, and the temperature of the dyeing solution in the padding tank is 20 ~25°C;

[0020] (c) Rolling: the fabric is quickly rolled onto a glass rod after being rolled out of the rolling machine, tightly wrapped with a plastic film, and hung in an oven;

[0021] (d) Stacking and color fixing: the fabric is stacked and fixed, the speed is 8-10r / min, the stacking temperature should be 22-27°C higher than the temperature of the rolling tank, and the ambient temperature is kept at 20-40°C, and stacked...

Abstract

The invention discloses a reactive dye cold-pad batch dyeing process for a pure cotton fabric. The process comprises the following steps: preparing dyeing liquor, rolling, batching, yarding and performing fixation, and washing. The problems that before and later color difference, left-center-right color difference, fabric covering black gas, seam mark and shallow edge easily occur in the dyeing production process and the like are solved, and the process is convenient to operate, uniform in coloring and high in color fastness.

Description

[0001] technical field [0002] The invention belongs to a dyeing process, in particular to a cold pad-batch dyeing process of pure cotton fabric with reactive dyes. [0003] Background technique [0004] The cold pad-batch dyeing process has low investment in equipment, low infrastructure costs, strong adaptability, low energy consumption, high dye utilization rate, less pollution, and good cloth surface effect of dyed products. The color is full, washable and non-fading, and is increasingly used in the production of clothing fabrics. However, this process is prone to problems such as front-to-back color difference, left-middle-right color difference, black gas on the cloth surface, seam head print and edge lightness during the dyeing production process. [0005] Contents of the invention [0006] In order to overcome the above-mentioned defects in the prior art, the object of the present invention is to provide a cold pad-batch dyeing process of pure cotton fabric wit...
