Problems solved by technology

[0002] Denim clothing has been born for more than 100 years, and it has been loved by consumers at home and abroad for a long time. However, with the continuous improvement of living standards, people's demand for personalized clothing is getting higher and higher. Far from meeting people's consumption needs, denim discharge printing technology has emerged, making denim more abundant
The traditional discharge printing of denim refers to using chemical methods to make the indigo base color of denim into white or other colors on the indigo base color of denim, but many printing pastes in the prior art contain dimethyl Phenylbenzyl ammonium chloride disulfonate calcium salt, this raw material has a great impact on the environment, so it is urgent to develop an environmentally friendly printing paste
