Abstract

The invention discloses a method for improving color depth and fastness of natural brown baffeta. The method comprises the following steps of (1) preparing a color-increased solution; (2) preparing a fixation solution; (3) pretreating; (4) carrying out color-increased treatment; (5) carrying out fixation treatment. By adopting the method provided by the invention, the color depth of the natural brown baffeta can be remarkably improved, the soaping fastness and the color fastness to sunlight are also remarkably improved, and the color depth, the soaping fastness and the color fastness to sunlight commonly reach to 4 to 5 grades so as to fully meet the commercial application requirement.

Description

technical field [0001] The invention belongs to the field of textile science, in particular to a method for improving the color depth and fastness of natural brown cotton fabrics. Background technique [0002] Compared with white cotton, natural colored cotton products are more beneficial to human health, and related processes such as printing and dyeing are reduced in the formation process of the products, which caters to the slogan of "green revolution" put forward by human beings and reduces environmental pollution. As far as our country is concerned, the development of natural colors will help the country continue to maintain its status as a major textile exporter, and it is even more important for breaking the international "green trade barriers". It is optimistically estimated that in the next fifteen years, the total amount of natural colored cotton products will be equal to the total amount of white cotton products. At present, there are mainly two kinds of natural ...
