Abstract

The invention relates to a natural dye dyeing method for kapok fibers. The natural dye dyeing method comprises the steps: the kapok fibers are subjected to alkali treatment, and the kapok fibers subjected to alkali treatment are obtained; the kapok fibers subjected to alkali treatment are placed into a polyethylene glycol solution, and after treatment, washing and drying are conducted; the kapok fibers subjected to polyethylene glycol treatment are subjected to plasma surface treatment, and the kapok fibers subjected to plasma treatment are obtained; the kapok fibers subjected to plasma treatment are placed into a cationic modifier to be stirred, after taking out, baking treatment is conducted, then the baked kapok fibers are washed and dried, and the modified kapok fibers are obtained; and the modified kapok fibers are taken to be added into a mordant to be subjected to pre-mordanting, and then the mordanted kapok fibers are placed into a natural dye to be dyed. According to the natural dye dyeing method for the kapok fibers in the technical scheme, the problems involved in the background art that a large amount of colored waste water is generated due to dyeing of the kapok fiberswith a reactive dye, the treatment difficulty is increased, and the color fastness cannot be ensured can be effectively solved.

Description

technical field [0001] The invention relates to the technical field of kapok fiber dyeing, in particular to a natural dye dyeing method of kapok fiber. Background technique [0002] As a natural cellulose fiber, kapok fiber has a thin cell wall that is almost transparent; it has a high hollowness and is currently the fiber with the highest hollowness; its specific gravity is only 1 / 5 of that of cotton fiber; Sound insulation, antibacterial and mite removal, and skin-friendly properties have shown very good performance. At present, kapok fiber has been widely used in the filling of cotton clothes and quilts, heat-insulating and sound-absorbing materials, buoyancy materials for water life-saving products, and oil-absorbing materials. [0003] Compared with ordinary fibers, kapok fiber has low cellulose content and high lignin content, and its surface is covered by foreign substances such as fat wax, so the dye is not easy to spread on the fiber surface, which directly causes ...
