Problems solved by technology

[0003] Although vat dye suspension pad dyeing and reactive dye pad-drying-pad-steaming dyeing processes have long been mature processes, in production practice, due to reasons such as dyes or process control, certain color fastness of the final product may still be encountered. Unqualified problem, vat dyes are mainly manifested in the chlorine bleaching fastness of bright blue and the wet ironing fastness of M gray, and the publication number is 104264518A. A kind of new cold rolling dyeing side has adopted vat dyes, but in dyeing Lye is used in the process, which increases the generation of sewage
General reactive dyes are mainly shown in the light fastness of light-colored fabrics and the rubbing fastness of fabrics; publication number is a kind of reactive dye surface dyeing auxiliary agent and preparation method and application thereof of 104372691A, has used reactive dyes, but also simultaneously A lot of auxiliaries are added and the process is complicated. In the general reactive dyes in the pure cotton process, the wet and dry fastness and washing fastness are difficult to meet the satisfaction of consumers. Therefore, how to select suitable dyes and optimize the dyeing process is to determine the dyeing effect. key factor

Abstract

The invention discloses a pure cotton cloth dyeing method. The dyeing method comprises the steps of dyeing, primary water washing, soaping, secondary water washing, softening, dehydrating, scutching and drying, and is characterized in that a dye used in the step of dyeing is selected from neutral fixation reactive dye and acid dye series, the use amount of the dye is 6-12 (%, o.w.f), the use amount of salt is 40-60 (g / L), and the pH of an adopted buffer solution is adjusted to be 7. Through adoption of the dyeing method, a dyed product is good in effect, high in quality, full in color, washable, and free of fading, so that the dryness fastness and the water washing fastness of cotton cloth are greatly improved.

Description

technical field [0001] The invention relates to the field of dyeing processing, in particular to a method for dyeing pure cotton cloth. Background technique [0002] Cotton fabric dyeing mainly uses general reactive dyes and vat dyes. Reactive dyes have the characteristics of bright color, excellent wet fastness, strong applicability, convenient use and low cost, and are suitable for dyeing. Vat dyes have the characteristics of complete color spectrum and high fastness, and are suitable for dyeing medium and light colors. Color fastness is one of the important indicators to measure the intrinsic quality of textiles. The nature of external effects on textiles during the wearing process is different, and there are various corresponding color fastnesses, such as sun exposure, soaping, climate, friction, sweat stains, Ironing, chlorine bleaching color fastness, etc. [0003] Although vat dye suspension pad dyeing and reactive dye pad-drying-pad-steaming dyeing processes have ...
