Abstract

The invention provides a water-free washing process applied to jean fabric. The process provided by the invention has the following procedures of: (1) providing a jean garment after being pretreated; (2) providing a catalyst which can be used for effectively enhancing the efficiency of ozone; (3) preparing the catalyst into a solution and coating at the specific position of the jean garment to be washed; (4) placing the jean garment coated with the catalyst under a collaborative environment of ozone and ultrasonic waves for carrying out treatment; and (5) carrying out the aftertreatment of washing, drying and the like on the jean garment after being treated. Compared with a traditional jean cloth washing method, the jean garment is treated by utilizing the synergistic action of the ozone and the ultrasonic waves and the catalytic action of the catalyst, and the efficiency of the ozone can be largely enhanced, so that the color of dye is quickly oxidized for discoloring. Moreover, the method has the advantages that the procedures are short, the energy consumption is little, water is saved, zero discharge can be achieved basically, the equipment cost is low, the operation is easy and the like. The pollution of the washing industry can be effectively solved.

Description

technical field [0001] The invention relates to the field of finishing of textiles. Background technique [0002] The denim washing industry is a major sewage discharger in the textile finishing industry. The wastewater discharged is large in quantity, high in organic pollutants, highly toxic, and difficult to degrade. It is a relatively difficult-to-treat polluted wastewater. With the development of the chemical industry, the variety of dyes has increased, and the difficulty of treating denim washing wastewater has greatly increased, and the corresponding sewage treatment costs have also greatly increased. [0003] It has been found through research that ozone is a strong oxidizing gas and has a strong bactericidal effect. It can oxidize and decolorize the color of dyes and paints. However, due to the low ozone output and low oxidation efficiency, there are still few places where it is applied to the washing water industry. After investigation, it is found that ozone can...
