Meanwhile, the production process efficiency is low due to the production line, leading to resource waste. Since water, chemicals, and energy account for more than 70% of total production costs in the textile industry, reducing the use of these energy inputs plays an important role. On the other hand, the construction of waste treatment stations must also meet statutory waste content standards. This paper presents the results of a number of production options to reduce environmental pollution and limit wastewater in the textile and dyeing industry: Shorten some production
Replacing Sulfuric Acid H2SO4 with Acetic Acid (CH3COOH) effectively ensures dyeing quality and is environmentally friendly. We hope that our research will bring reference value to textile and dyeing training institutions as well as its high applicability for Vietnam's textile and dyeing factories, in line with the circular economy model, green and lasting.
