Dyeing and finishing technology for high-elastic habijabi fabric

Abstract

The invention discloses a dyeing and finishing technology for a high-elastic habijabi fabric. The dyeing and finishing technology comprises a pretreatment process, a dyeing process and a setting process, wherein the pretreatment process comprises an open-width desizing process, a machine cylinder cloth scouring process, a pre-setting process and a slack alkali peeling process which are conducted in sequence; a dyeing agent adopted in the dyeing process is prepared from a dyeing additive and dyes which are disperse dyes; in the dyeing process, dyeing is conducted by using a high-temperature andhigh-pressure airflow dyeing machine, when the temperature of a dyeing vessel of the dyeing machine reaches 45 DEG C, the dyeing additive and the disperse dyes start to be injected respectively, andthe pH value of the dyeing bath is 5-6. Through the reasonable design of the pretreatment, dyeing and setting processes, the dyeing effect on the fabric can be improved, the dyeing uniformity and thecolor fastness of the fabric can meet requirements of customers, moreover, the elasticity of the fabric cannot be damaged, and the fabric is high in deformation memory property, soft in handfeel and high in dimensional stability.

Description

technical field [0001] The invention belongs to the technical field of textile printing and dyeing, and in particular relates to a dyeing and finishing process of high-elastic hemp fabric. Background technique [0002] In recent years, with the upgrading of domestic consumption and the advancement of science and technology, the market demand for elastic fabrics has gradually increased. In the process of production and use, the traditional elastic fiber spandex gradually exposed some problems, such as the dyeing and finishing temperature is too high, which may easily cause the loss of fabric elasticity; the yarn coating is not ideal, the spandex filaments are exposed, and the spandex fiber is not dyed and white Causes the presence of glowing spots on the fabric. Spandex fiber has gradually been unable to meet the current diversified industrial needs. Therefore, the research and development of spandex alternative and upgraded products has been widely carried out in scientific...

AI Technical Summary

Problems solved by technology

If the pre-treatment process or parameters are not used properly, not only the softness of the fabric cannot be guaranteed, but also the subsequent dyeing quality will be affected

[0005] As for the dyeing process of high-elastic hemp fabrics, traditional liquid jet dyeing machines have defects such as large bath ratio, high energy consumption, high sewage discharge, and low efficiency. It also poses a serious threat to my country's water resources and ecological environment
