Problems solved by technology

Its desizing process adopts the method of alkali-acid desizing, and its scouring and bleaching still use caustic soda and hydrogen peroxide as the main boiling and bleaching agents, which do not meet the requirements of modern environmental protection
[0006] At the same time, the oils applied or stained during the fiber weaving process, the warp sizing materials and heavy metals during weaving, these impurities and oils are difficult to remove by conventional enzyme treatment, especially the gray cloth contains a large amount of Heavy metals, resulting in the reduction of enzyme activity, which brings great difficulty to the subsequent enzyme treatment

Embodiment 1

[0054] Example 1 An unbleached and undyed knitted cotton textile prepared by an ecological cleaning method, the preparation process comprising:

[0055] (1) Pre-washing of knitted cotton textiles

[0056] Soak the knitted cotton textiles to be treated in a clear water environment system about 30 times the weight of the knitted cotton textiles, so that the knitted cotton textiles to be treated are completely infiltrated; then, the water temperature of the clear water environment system is raised to 30°C, and lipase is added, Carry out heat preservation treatment; Knitted cotton fabric is pure cotton fabric (100% cotton, gram weight 190g / m 2 , friction coefficient 3-4, bursting strength ≥ 500N); the amount of lipase in the clean water environment system is 0.5g / L; Fully react with lipids or other oily impurities on knitted cotton textiles to form water-soluble alcohols, fatty acids and other water-soluble impurities and remove them. The lipase is acid lipase; the enzyme activi...

Abstract

The invention provides an unbleached and non-dyed knitted cotton textile prepared by an ecological cleaning method. A preparation technology of the knitted cotton textile comprises a pre-washing procedure of the knitted cotton textile, an enzyme refining procedure, a treatment procedure for surface fluffs of the knitted cotton textile and a chelating and heavy metal removing procedure. In a production process of the knitted cotton textile, the water consumption is 5.52 to 6.21t / 100kg and is much lower than the water consumption of boiling in a conventional method; the removal rate of pectin is95.77 to 98.75 percent and the removal rate of heavy metal is 91.51 to 99.58 percent; the strictest requirements on the content of the heavy metal in infant textile standards are met.

Description

technical field [0001] The invention relates to a non-bleaching and non-dying cotton textile, in particular to a non-bleaching and non-dying knitted cotton textile prepared by an ecological cleaning method. Background technique [0002] The fabrics directly coming off the loom after dyeing and finishing are collectively referred to as raw fabrics or gray fabrics. Gray cloth often contains a certain amount of impurities, such as wax, pectin, nitrogenous substances, ash, natural pigments and cottonseed hulls, etc., oils on chemical fibers, oils applied or stained during the weaving process, and warp yarns during weaving. The sizing agent, etc. If these impurities, oils, and dirt are not removed, they will affect the color and feel of the fabric, and further affect the intrinsic quality of the fabric. Therefore, general gray cloth products must be scouring and bleaching. For the scouring and bleaching of cotton-containing fabrics, it generally includes the processes of raw f...
