Abstract

The invention provides a water washing process for denim clothes. The water washing process comprises the following steps: performing pretreatment, enzyme washing, ferment washing, water washing, primary dewatering, primary drying, monkey washing, neutralization treatment, softening, secondary dewatering and secondary drying on the denim clothes, and obtaining a water-washed finished product. The water washing process has the beneficial effects that no odor is generated during neutralizing reduction, so that the air quality in a working environment is not affected; by the use of a high-concentration product, the use amount is small, and the warehousing pressure of a factory is relieved; residual manganese ions can be quickly removed, and thetreatment time is shortened; the color of bleaching liquid can be removed; the number of cleaning times is reduced, and the sewage treatment pressure is relieved; the sewage COD is low; the sand level is clear, and the class of the denim clothes is improved.

Description

technical field [0001] The invention relates to a fabric washing process, in particular to a washing process for jeans. Background technique [0002] Denim has experienced hundreds of years of refinement from tooling to fashion. Over the past century, denim has never left the popular stage. It can be the most economical life clothing or the most individual fashion. It responds to ever-changing trends with a calm face. Popularity. The effect created by the washing process has become a classic of denim clothing. In recent years, the value and beauty of the whole denim has been more and more reflected in the washing process, among which hand rubbing, cat whiskers, and monkey spraying are the most popular washing processes. The so-called horse spraying is to use a spray gun to spray different concentrations of potassium permanganate solution on the denim garment according to the design requirements, and use the oxidation of potassium permanganate to destroy the indigo dye or s...
