Description
Technical Field
The invention belongs to the field of cotton fabric dyeing, and particularly relates to a method for modifying and dyeing an all-cotton fabric.
Background
Cotton fabric is hygroscopic, breathable and soft in hand feeling, is mainly used for making underwear, sports wear, T-shirts and the like, and is widely used in the field of outerwear and even fashionable clothes due to rich varieties and high grade. The cotton knitted fabric is mainly dyed by reactive dyes, and the dyeing process technology is a mature process for dyeing cotton fabrics.
The natural dye is natural, harmless to human health, good in compatibility with the environment, free of environmental pollution, biodegradable, and meets the requirements of modern people on self health and environmental protection. Therefore, the process technology for reducing the water for dyeing is more in line with the modern concept of environmental protection and ecology.
Most dyes have higher dye uptake and color fastness on protein fibers such as silk, wool and the like, while the dye uptake on cellulose fibers such as cotton, hemp and the like is low, the color fastness is also poor, and the dye can reach higher dye uptake and color fastness only by being treated by a mordant. The dye has better dye-uptake and dye fastness on protein fibers, and reactive groups in the cellulose fibers only have hydroxyl groups, are single in type and lack positive groups similar to amino groups. Therefore, aiming at the defects that the affinity between the natural dye and the cotton fiber is small, the type of the active group on the cotton fiber is single, and the reaction capability is not strong, the chemical modification is greatly tried in the field to the cotton fiber, so that the surface of the cotton fiber has cationic property, the binding capability of the cotton fiber and the natural dye is enhanced, and the dye uptake and the color fastness of the natural dye on the cotton fabric are improved.
The existing modifier, especially the small molecular modifier has the advantages of good leveling property and permeability, but poor stability, so that the problems of large required dosage, low effective utilization rate and the like exist, and certain environmental pollution is caused.
Therefore, in the field of dyeing of cotton fabric by using reactive dyes, a modifier and a dyeing process which are more environment-friendly and have higher activity are still needed.
