Embodiment 1

[0019] Cotton fabrics that have been pre-treated by boiling, bleaching, etc., are padded with anti-dyeing agent (10-20 g / L), and dried in a dryer; padding with dyeing solution containing reactive dyes and alkali agents (soda ash or baking soda), with liquid The rate is 80-100%; the fabric is steamed in saturated steam for 60-90 seconds at a temperature of 100-102°C, and then washed in cold water, hot water (70-90°C), soaping (90-95°C), and hot water (70-90℃), cold water washing, drying and other post-treatment.

[0020] The chemical structure of the anti-dyeing agent is as follows:

Abstract

The invention relates to a method for dyeing slubby yarn cotton fabrics into a raindrop or silk rain style, which belongs to the field of dyeing of the slubby yarn cotton fabrics. The method comprises the following steps of: padding the slubby yarn pure cotton fabrics subjected to boiling and bleaching pretreatment with a resisting agent, oven-drying the padded slubby yarn pure cotton fabrics, padding the slubby yarn pure cotton fabrics with a reactive dye and an alkaline agent, and performing steaming, color fixation, washing and oven-drying to obtain the products. The method of the invention has the advantages of simplicity, low cost and suitability for industrial production; and the dyed fabrics are bright in color, complete in color pattern and high in color fastness, and have the unique dyeing style of different color shades, raindrops or silk rain.

Description

technical field [0001] The invention belongs to the field of dyeing slub yarn cotton fabrics, in particular to a method for dyeing slub yarn cotton fabrics in raindrop or rain silk style. Background technique [0002] The slub yarn has the characteristics of thin and thick yarns, and its fabric texture has a prominent slub effect. Slub yarn is widely used in the production of various fabrics, which is in line with the current fashion trend of advocating natural style. At present, the slub yarn is mainly dyed with indigo dye. Since the slub part of the slub yarn is thicker, the twist added to the slub part during spinning is also less, and the fiber of the slub segment is looser, so that the thicker part of the slub yarn is dyed. The absorption of dyes by the fine segments is inconsistent, and the style of raindrops or raindrops will be formed according to the length of the bamboo nodes. And indigo dyeing has the defect of single color and luster, and the fabric after dyein...
