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 high-density poplin. The method comprises the steps of (1) singeing; (2) padding, rolling and cold-batching; (3) tight continuous padding alkali-oxygen liquid short steaming; (4) mercerizing; and (5) drying. The all-cotton high-density poplin is treated with the method, so that the efficiency can be improved and the pollution can be alleviated.

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] Pure cotton high-count and high-density poplin, soft luster, fine texture, smooth and soft to the touch, good moisture absorption, breathable and comfortable to wear. With elegant and vertical style, it is one of the main fabrics for middle and high-end shirts and summer clothing. [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...
