Problems solved by technology

However, long-term high temperature and high alkali treatment will easily damage the cotton fiber and make the fabric feel rough.
At the same time, due to the long process flow, a large amount of energy and water are consumed, and the discharge raffinate has high alkalinity, high BOD and COD values
Increased the burden of sewage treatment

Abstract

The invention relates to a pretreatment method for all-cotton single-yarn drill. The method includes the steps of singeing; padding, rolling and cold batching; compact continuous padding alkali oxygen liquid short steaming; mercerizing; drying. The method is adopted to treat the all-cotton single-yarn drill, efficiency can be improved, and pollution can be reduced.

Description

technical field [0001] The invention relates to the technical field of printing and dyeing, especially the technical field of cotton fabric printing and dyeing. Background technique [0002] Cotton yarn card products have the characteristics of even and clean cloth surface, simple and soft, stable shape, moisture absorption and wear resistance. Currently the preferred fabric for casual long and short pants. [0003] Pectin, wax, protein and other natural impurities in natural cotton fibers reduce the hydrophilicity of cotton fibers. A large amount of insoluble protopectin in pectin has a large molecular weight, and the hydrogen ions on the shuttle group in the molecule can be replaced by positive divalent calcium and magnesium ions to form water-insoluble calcium and magnesium pectin salts; at the same time, the shuttles in pectin The pectin group and the hydroxyl group may also form acid and hydrogen bonds with the hydroxyl groups in the cellulose, so that the pectin mole...
