Embodiment 1
[0034] (1) The cotton cloth is singed at a speed of 40m / min, and the hairiness on the cloth surface is removed to obtain the gray cloth;
[0035] (2) Put the gray cloth into the dye vat containing 7g / L high alkali-resistant penetrating agent for wetting, and the bath ratio is 1:4;
[0036] (3) Spray the wet gray cloth in the dyeing vat with 2g / L lye at a spray speed of 12.5L / min, and atomize and spray for 30min;
[0037] (4) Spray the gray cloth with 180g / L lye in the dyeing vat, the spraying speed is 4.16L / min, atomize and spray for 60 minutes, and blow the cloth surface with a 55Hz fan during the spraying; outside the dyeing vat Cooling water is provided to keep the temperature of the lye in the dye vat within the range of 20-25°C;
[0038] (5) Drain the lye in the dye vat, add 60-70°C hot water to overflow the cloth surface and wash it until the pH of the cloth surface is 10.5-10.8;
[0039] (6) Add hydrogen peroxide to the dye vat, the mass concentration of hydrogen pero...

Abstract
The invention relates to the technical field of printing and dyeing, and discloses an efficient environment-friendly mercerization-imitating dyeing and finishing process for cotton cloth. The processcomprises the following steps that singeing treatment and wetting are carried out on the cotton cloth; after 1.5-5 g / L of alkali liquor is sprayed, 160-200 g / L of alkali liquor is sprayed to gray cloth, and the cloth surface is blown open by adopting a fan in the spraying process; and the cloth surface is subjected to washing, bleaching, boiling, dyeing, shaping and steaming to obtain a finished cloth surface. In the process, alkali shrinkage, washing, bleaching and dyeing of the cloth surface are all completed in a dye vat, dyeing and alkali shrinkage are integrated, the concentration of theadopted alkali liquor is 160-200 g / L, the cotton cloth shrinks instantly and quickly, the stacking process is not needed, production equipment is simplified, the production cost is greatly saved, continuous production is achieved, the prepared finished cloth has a mercerization-imitating effect, the cloth surface is glossy, head-tail color differences are avoided, the hand feeling is fluffy, and resilience is good.
Description
technical field [0001] The invention relates to the technical field of printing and dyeing, in particular to an efficient and environment-friendly imitation mercerizing dyeing and finishing process for cotton cloth. Background technique [0002] The mercerizing dyeing and finishing process of cotton cloth can improve the handle, gloss and shrinkage stability of the finished cotton cloth. However, the investment cost of using a mercerizing machine is high. The traditional mercerizing dyeing process includes steps such as singeing, mercerizing treatment, wool erosion, dyeing, soaping and setting. The process is cumbersome and the processing cost is high. The light mercerized dyeing process has the characteristics of good moisture absorption, breathability and glossiness of ordinary mercerized fabrics, and it also has the characteristics of no trace, no dust, good bursting strength, and low energy consumption that ordinary mercerized fabrics do not have, such as CN 107435199 A ...
