Problems solved by technology

However, in the dyeing industry, cotton fibers dyed with reactive dyes are challenged by energy shortages such as water resources. At the same time, due to the structural characteristics of reactive dyes, some reactive dyed fabrics have relatively poor color fastness, so they cannot meet the requirements specified by customers. High temperature washing resistance, chlorine bleaching fastness, etc., thereby reducing product quality and ultimately affecting the development of yarn-dyed products

Embodiment Construction

[0014] This embodiment will be further described in detail below.

[0015] A kind of vat dye dyeing process of cotton fabric of the present invention, described vat dye dyeing process comprises the following steps:

[0016] (1) For dyeing, refer to the bath ratio information on the prescription before dyeing, the bath ratio is 1:5.5-6, and at the same time open the preset water level of the dyeing vat; put the cotton fabric in water, and then heat the water to 80°C, keep warm for 20 minutes with Gasthin dye; it should be noted that since the control of the water level before dyeing will directly affect the accuracy of the color depth and shade of the dyeing, in this embodiment, the water level is preset to ensure the depth of dyeing And the accuracy of shade, improve the dyeing effect.

[0017] (2), add auxiliary agent, in the aqueous solution of described cotton fabric, add auxiliary agent, described auxiliary agent comprises caustic soda, sodium hydrosulfite, dispersant, di...

Abstract

The invention relates to the technical field of vat dye dyeing technology in the textile industry, and in particular relates to a vat dye dyeing technology of a full-cotton fabric. The vat dye dyeing technology comprises the steps of dyeing, adding auxiliaries, maintaining temperature, washing by water, oxidizing, soaping, pickling, and post-processing, wherein the water level is needed to be controlled during dyeing in order to ensure the accuracy of the degree in dyeing and the color and gloss; the amount of used auxiliaries is needed to be adjusted based on an auxiliary quantity form during adding the auxiliary, so as to ensure the quality of the full-cotton fabric in dyeing; and the soaping is needed to be carried out twice so as to ensure the color and gloss. The vat dye dyeing technology of the full-cotton fabric has the characteristics of being simple in technology, good in dyeing effect, resistant to high-temperature washing, and resistant and firm in chlorire bleach, and improves the quality of the full-cotton fabric.

Description

technical field [0001] The invention relates to the technical field of vat dye dyeing in the textile industry, in particular to a vat dye dyeing process for cotton fabrics. Background technique [0002] Cotton fabric is a natural cellulose fiber that is popular among consumers. However, in the dyeing industry, cotton fibers dyed with reactive dyes are challenged by energy shortages such as water resources. At the same time, due to the structural characteristics of reactive dyes, some reactive dyed fabrics have relatively poor color fastness, so they cannot meet the requirements specified by customers. High temperature washing resistance, chlorine bleaching fastness, etc., thereby reducing product quality and ultimately affecting the development of yarn-dyed products. Contents of the invention [0003] The purpose of the present invention is to provide a vat dye dyeing process for cotton fabrics with good dyeing effect, high temperature washing resistance, chlorine bleachi...
