Problems solved by technology

Today, denim clothing has become one of the favorite clothing of the Chinese people, and has become an indispensable content in the life of Chinese consumers. With China's huge population of more than 1.3 billion, it is self-evident that the market capacity is huge! However, the traditional printing process of denim is yarn dyeing-weaving-clothes, and then different denim styles are washed through different washing processes. (Double snowflake washing), stone grinding washing (light and heavy grinding), stone rinsing, rinsing (light and heavy bleaching), enzyme, stone yeast, stone yeast rinsing, over-dyeing washing, etc., not only the process is complicated, but also the water consumption and sewage discharge It is not suitable for long-term development and survival in China where water resources are scarce
