DEVELOPMENT OF PERMANGANAT ALTERNATIVE EFFECT WASHING CHEMICALS IN DENIM WASHING PROCESSES

Abstract

The process of giving effect or attrition on the denim is a situation that develops day by day according to the fashion trends that have developed in recent years. The effect is to try to achieve a more matte appearance by gradually removing these materials by means of paint deformation, while the fiber is not allowed to break brittle on the working surfaces of the particles, where the hard and amorphous surfaces provide a kind of fine sanding function. The aging process is generally done to provide a random wear look and to break the uniform denim paint look. The most important of these can be listed as the difficulty of use, the fact that it contains permanganate, which is harmful to the environment, expected to be banned in the near future, and the absence of repeated use. By using Al2O3 material, which is in the oxide abrasive class, by adding liquid paraffin and TEA, which acts as a compatibilizing agent, at different rates, abrasion slurry was produced and its effects on denim products were investigated. In this study, the effects of particle size of oxide species, α- Al2O3 ratio in Al2O3 specific surface areas and impurities in Al2O3 were also investigated.
