Technical Field

The invention relates to the technical field of garment washing and dyeing, in particular to an anhydrous washing and dyeing process.

Background

Denim, also called split silk, is a thick yarn-dyed warp-faced twill, with dark warp yarn color, usually indigo, and light weft yarn color, usually light grey or scoured natural white yarn, also called indigo-blue industrial fabric. Starting in the western united states, grazing men are named for making clothes and pants. Denim is a dyed and woven yarn-dyed fabric, the traditional production method is that the yarn count used for the warp direction primary color is subjected to indigo dyeing, the dyed warp yarn is made into a beam, and then the fabric is woven. The pigment is used as a dye and is widely used in printing for a long time, and pigment dyeing is used for replacing the original traditional dyeing process with long dyeing process, large consumption and high dye cost of dyes such as active dyes, direct dyes, reduction dyes, landicin dyes and the like.

The washing process is an important link of the existing jeans wear production, and the traditional washing mode mainly removes the dye through different physical modes or chemical modes such as mechanical washing and the like so as to achieve the aim of decoloring. Most products can reach the factory requirement standard after being washed by water for many times. Therefore, the washing industry of the jeans is a large pollution discharge household in the textile finishing industry, the discharged wastewater is large in quantity, high in organic pollutant content, high in toxicity and difficult to degrade, and the washing industry belongs to polluted wastewater which is difficult to treat. With the development of chemical industry, the varieties of dyes are increased, the treatment difficulty of the washing wastewater of the jeans is greatly increased, and the corresponding sewage treatment cost is also greatly increased.

In conclusion, the existing jeans wear washing process is complex in process, high in energy consumption and low in production efficiency, a large amount of water resources are consumed in the washing process, and the washing process contains a large amount of substances such as alkali liquor, silicone oil and a softening agent, so that the discharged wastewater is high in toxicity and serious in environmental pollution.
