Problems solved by technology

At present, sodium metabisulfite is widely used as a reducing agent in the washing process, but this product has many shortcomings and hazards: (1) It will produce a large amount of pungent gas during neutralization and reduction, which seriously pollutes the air quality in the working environment; (2) It has obvious stimulating effect on skin and mucous membranes, can cause symptoms of conjunctiva and bronchitis, and direct skin contact can cause burns; (3) Excessive dosage results in high storage pressure and is prone to moisture; (4) Due to excessive dosage, it cannot remove the bleaching solution The color needs to be washed with a large amount of water, resulting in an increase in the pressure of wastewater treatment; (5) a large amount of use will lead to high COD / BOD in sewage

Abstract

The invention relates to a washing process for a denim garment. The washing process comprises the following steps: performing bio-enzyme de-sizing treatment in an amylase solution after performing denim garment fabric pre-treatment; performing enzyme washing by neutral enzyme powder; dehydrating and drying after cleaning with clean water; performing monkey wash on the fabric surface; performing neutralization treatment on the fabric which is subjected to monkey wash; adding a softening agent to perform softening treatment on the fabric; cooling the denim garment fabric to room temperature after dehydrating and drying, thereby completing washing on the denim garment. Compared with the prior art, the washing process has the advantages of quickly removing residual manganese ions, shortening the processing time, removing the color of a bleaching liquid, reducing the cleaning frequency, being low in sewage COD (chemical oxygen demand), and the like.

Description

technical field [0001] The invention relates to a fabric treatment process, in particular to a denim garment washing process. 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 dy...
