Description
Technical Field
The invention relates to a method for dyeing cotton fabrics by laccase-catalyzed oxidation of walnut green skin powder, belonging to the technical field of textile printing and dyeing.
Background
The walnut green seedcase is used as a raw material, the dark brown natural pigment can be obtained, the pigment has strong adhesion capacity and rich raw materials, the comprehensive application of resources can be realized, and meanwhile, the pigment has the advantages of simple production process, high yield, low cost, safety and no toxicity, and can be used for dyeing fabrics. The walnut green husk pigment is dissolved in water and diffuses into the fiber, and the pigment is converted into macromolecules and is fixed inside the fiber through the laccase catalytic oxidation process.
Mordants are generally used in dyeing natural dyes to increase dye uptake. The traditional mordant is mostly salt of metals such as copper, iron, aluminum, chromium and the like. The use of heavy metal ions to a certain extent makes the ecological and environmental significance of natural dye dyeing greatly reduced. In the context of today's strict limitation of the heavy metal ion content in textiles, there is a need to develop new dyeing methods to replace the traditional mordant dyeing.
Aiming at the problems of dyeing by using a conventional mordant of a natural dye, the invention provides a method for dyeing cotton fabric by using laccase-catalyzed oxidation of walnut green skin powder. Laccase has the advantages of high catalytic efficiency, mild reaction conditions, reproducibility and the like, and is considered as an ideal biocatalyst for replacing a chemical catalyst. Laccase has strategic significance for solving the problem of serious environmental pollution, and accords with the trend of green manufacture and sustainable development. After the cotton fabric is subjected to cationic modification, negative charges carried on fibers are reduced, so that the coulomb repulsion of the negative charges on the fibers to dye anions in the dyeing process is reduced, the affinity of the dye to the fibers is increased, the dye-uptake is improved, the color of the dyed fabric is stabilized, the loose color is reduced, the color fixing performance is good, and the rubbing fastness is improved. The laccase used in the invention catalyzes and oxidizes the walnut green husk pigment to dye cotton fabric without using chemical auxiliaries such as mordant and the like, thereby achieving the effect of ecological environmental protection. Meanwhile, the dyed fabric has better color fastness.
