Technical Field
The invention belongs to the technical field of textile dyeing, and particularly relates to a dyeing process for producing denim yarn by using a reactive dye dyeing method.
Background
The jean fabric, one of the most popular fabrics, plays an increasingly important role in daily life, and is popular with consumers. At present, most of the conventional denim fabric is dyed by indigo and vulcanization, the indigo denim fabric is single in color and cannot meet the requirements of people on the product, and the sulfur dye has the defects of poor color light stability, incomplete color spectrum, high dyeing sewage treatment cost and the like. The colored jean fabric produced by adopting the over dyeing method has the problems of complex processing, unstable color light, poor reproducibility and the like. With the demand of consumers for diversified jean fabrics, the production of the jean fabrics by using reactive dyes becomes one of the important points of research. The reactive dye has bright color, complete chromatogram and excellent color fastness, but the reactive dye has fast dyeing and permeation, loses the effect of yarn loop dyeing, namely the white core of the jean after the yarn dyeing, and is difficult to realize the antique style of the jean, thereby limiting the application of the reactive dye on the jean yarn fabric.
At present, the reactive dye is used for dyeing the jean yarn by using the multi-purpose sizing and dyeing combined long vehicle, and equipment is required to be modified to meet the requirement of high-temperature baking so as to realize high-temperature color fixation in a short time, so that the reactive dye and fiber can quickly react, and the production stability is improved. The invention realizes the production of the jean yarn by using the reactive dye by using the single yarn sizing machine, realizes the style of the jean white core, and can enrich the color system of the jean yarn to produce the color jean yarn.
At present, no article or patent report exists about the dyeing process for producing the denim yarn by using the reactive dye dyeing.
