Dyeing and finishing process of textile

Abstract

The invention relates to a dyeing and finishing process of a textile. The dyeing and finishing process of the textile comprises the steps of carrying out pre-treatment, dyeing, washing, neutralizing, soaping and washing on the textile. The dyeing and finishing process of the textile has the beneficial effects that when a low temperature dyeing and finishing process is compared with a middle temperature dyeing and finishing process, in a dyeing step, firstly in dyes of dark series, three primary dark colours are combined, advantages can be shown more obviously for dyeing of black, dark green, dark brown, light army green, dark gray, purplish red and garnet red series, the dyes used in the dyeing and finishing process of the textile has high pile-on property, high absorption rate and good compatibility, compared with middle temperature dyes, dye absorption rate is high, raffinate chromaticity is low, and dosage of low temperature active dyes in coffee, army green and gray dyeing processes is 40-70% that of middle temperature active dyes; production cost of a dyeing and printing enterprise is reduced compared with dark colour series, the problem of high pollution control cost is solved, and treatment cost can be reduced while discharge capacity is reduced for the printing and dyeing industry by adopting the dyeing and finishing process of the textile.

Description

Technical field [0001] The invention involves a spinning technology. Background technique [0002] In the fabric dyeing process, the dyeing step is used in the dyeing steps, but the medium temperature -type dye is large, but the amount of medium temperature dye is relatively large, and it is required to use sodium carbonate as a fixing agent during the dye.Large, 30g / L (dosage per liter of water) is required to the largest.Taking one ton of dark fiber textiles as an example, the bath ratio is 1:10, that is, the amount of water is 10L, the amount of sodium carbonate required is 300kg, and the cost is expensive. Invention content [0003] In response to the problems existing in existing technology, the purpose of the present invention is to provide a technical solution for the dyeing process of textiles. [0004] The dyeing process of a textile, including the front processing, dyeing, water washing, neutralization, soap washing, and water washing of textiles. It is characterized b...
