Problems solved by technology

Cationic modified cotton is widely used in the fields of knitting and garment dyeing. Cationic modified cotton yarn has many advantages in dyeing, but conventional methods dye this kind of yarn, because the dyeing speed is too fast and it is difficult to control, so the uneven dyeing is the main problem. However, it has not been widely applied and promoted in actual production
[0003] Existing patents involve many patents on cationic modified cotton, and the patents mainly focus on the practice of fiber, yarn or cloth modification process, but less practice on dyeing effect. There are no patents or literature reports on beam dyeing, and the cheese or warp beam dyeing method for cationic modified cotton yarn is still in its infancy

Abstract

The invention provides a cone yarn or beam dyeing method for cationic modified cotton yarns. Even dyeing can be realized under the condition of environmental protection, and the method is simple and convenient in technology and low in cost. Compared with a conventional dyeing method, the method has the advantages that dyeing technological process is improved, the problem of uneven dyeing is solved, outside-to-inside color difference is 4 level (rating standard: GB/T 250-2008), technological operation is simple and convenient, environments are protected, and energy is saved.

Description

technical field [0001] The invention belongs to the technical field of textile dyeing, and in particular relates to a cheese or warp beam dyeing method for cationic modified cotton yarn. Background technique [0002] The printing and dyeing industry is an industry with high pollution, high energy consumption and high cost. From the perspective of the development situation of the printing and dyeing industry and my country's environmental protection requirements, the processing costs and COD emission indicators of traditional printing and dyeing are very high. Cationic modified cotton dyeing usually does not need to add saline and alkali, has high dyeing rate, low COD value of wastewater, simple process and low cost. It is an environmentally friendly dyeing form that has developed rapidly in recent years. Cationic modified cotton is widely used in the fields of knitting and garment dyeing. Cationic modified cotton yarn has many advantages in dyeing, but conventional methods d...
