Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of short-process dyeing equipment, and in particular relates to a short-process dyeing vat for cotton fabrics with environmentally friendly dyes. Background Art
[0002] The short-process dyeing of cotton fabrics with environmentally friendly dyes is a dyeing process that has been widely promoted in the printing and dyeing industry in recent years. Short-process dyeing mainly involves the control of the moisture content of the fabric and the interaction between the dye and the fiber. In this process, the fabric is first dipped in the dye, and at this time there is no chemical bond between the dye and the fiber, but it is only mechanically attached to the fiber. Then, the fabric goes through a drying process to diffuse and fix the dye particles inside the fiber. The short-process dyeing process has the advantages of short dyeing time, low energy consumption, and simple wastewater treatment.
[0003] However, when using environmentally friendly dyes to dye cotton fabrics in a short process, the coloring performance of environmentally friendly dyes is worse than that of conventional dyes, and the process temperature of short process dyeing is high, resulting in a greater shrinkage rate of cotton fabrics than that of traditional processes. In order to solve the above problems, the utility model hopes to provide a cotton fabric environmentally friendly dye short process dyeing cylinder. Utility Model Content
