Problems solved by technology

The dye solution contains a large amount of chemical additives such as soda ash, caustic soda, urea, anti-swimming agent, etc., which brings serious pressure to sewage treatment
In addition, the use of equipment such as drying cylinders and infrared devices on the dyeing machine will consume a lot of steam energy and electric energy, and the energy consumption is relatively large.
In addition, long car pad dyeing needs to carry out large-scale trial production, adjust the dyeing solution according to the large-scale test, and then carry out mass production. The success rate of one-time sample pad dyeing is low, and the sample cost is high.

Abstract

The invention provides a cold dyeing process for a cellulose fiber fabric. The process comprises the following steps of: a, pre-treating a fiber fabric; b, preparing mixed alkali liquid and dye solution respectively; b, pumping the mixed alkali liquid and the dye solution into a chassis by using a proportioning pump to perform mixing so as to obtain dye solution; d, soaking the fiber fabric into the chassis to pad the dye solution; e, curling the padded fiber fabric; f, heaping and color-fixing the curled fiber fabric; and g, after heaping, finishing dyeing by washing, soaping, washing, drying, tentering and finishing. The cold dyeing process has the advantages that: dyeing can be finished at normal temperature without a vapor-solid process; washing and post finishing can be performed, and the energy consumption is low; and the dye solution contains a little chemical auxiliary agent, and is favorable for sewage treatment. Compared with long rolling and dyeing, the cold dyeing process has greater advantages that the dyeing production is performed by adjusting directly based on a small sample formula without trying a large sample, the one-time success rate is high, and the sample cost is reduced.

Description

technical field [0001] The invention relates to a dyeing process of cellulose fiber fabrics, in particular to a cold dyeing process. Background technique [0002] At present, the dyeing of cellulosic fiber fabrics has always been the long-car pad dyeing process. The main production process is to pre-treat the fiber fabrics, then prepare a dye solution, and then pad the dye (using two dipping and one padding). Drying (at a temperature of 80°C-100°C), padding and steaming the color-fixing solution, followed by steaming, water washing, soaping, water washing, drying, tentering and finishing in order to complete the dyeing. The dye solution contains a large amount of chemical additives such as soda ash, caustic soda, urea, anti-swimming agent, etc., which brings serious pressure to sewage treatment. In addition, the use of equipment such as drying cylinders and infrared devices on the primer machine, that is, the dyeing machine, will consume a large amount of steam energy and e...
