METHOD AND SYSTEM FOR IMPROVING WEARABILITY OF TEXTILE MATERIAL AND/OR DECOLORING TEXTILE MATERIAL

WIPO Patent Application WO/2022/032436

A1

A method for improving wearability of a textile material and/or decoloring a textile material, comprising the following steps: performing drying processing for about 0.5-3 hours by heating a textile material to 95-120°C under an inert atmosphere or a vacuum condition, and then raising the temperature to perform processing for about 3-48 hours. The textile material has a soft luster, and the wearability of the textile material such as durability, a style, and a feel is improved; the method can achieve complete or partial stripping of the textile material, thereby obtaining a product having a special style. A system for improving wearability of a textile material and/or decoloring a textile material, comprising a reaction apparatus, a gas purifier, and a medium circulation apparatus (an inert gas circulation heater or a vacuum pump), and the three being connected by means of pipes. The method and system are simple and flexible to operate, low in production cost, free of use of chemical additives and free of generation of wastewater, and easy for industrial implementation.
