Problems solved by technology

[0004] The purpose of this invention is to provide a kind of water-saving dyeing process of cheese to solve the pretreatment process of traditional cotton, hemp and its blended cheese, which is to use caustic soda, the oxygen bleaching process of additives such as hydrogen peroxide, adopt this process because the pH value is relatively high High, many kinds of additives, long reaction time, high weight loss rate of yarn, fiber damage and brittleness, reduced strength, rough hand feeling, high water consumption, etc.

Embodiment 1

[0022] This example provides a water-saving dyeing process for cheese, including yarn pretreatment, dyeing and post-dyeing treatment; yarn pretreatment: add refining agent to water at 100°C, boil the yarn for 30 minutes, and wash in cold water for 7 Minutes; Dyeing: including three stages of adsorption, diffusion and fixation in sequence, adding dyes to yarn dyeing for 15 minutes in the adsorption stage, adding neutral electrolyte to promote dyeing for 3 minutes in the diffusion stage, using 15g / Soda ash is fixed at 55°C for 40 minutes, soaked for 60 minutes; post-dyeing treatment, wash the fixed yarn in cold water for 7 minutes, use acetic acid for reduction cleaning at 50°C for 7 minutes, and then wash in cold water for 7 minutes Finally, soaping twice at 95°C for 10 minutes, adding a color-fixing agent and raising the temperature to 28°C for 7 minutes, adding a softener and soaking for 30 minutes to complete the dyeing.

Embodiment 2

[0024] This example provides a water-saving dyeing process for cheese, including yarn pretreatment, dyeing and post-dyeing treatment; yarn pretreatment: add refining agent in water at 95°C, boil the yarn for 35 minutes, wash in cold water for 9 Minutes; dyeing: including three stages of adsorption, diffusion and fixation in sequence, adding dyes to dye the yarn for 18 minutes in the adsorption stage, adding neutral electrolytes to promote dyeing for 11 minutes in the diffusion stage, and using 20g / Soda ash is fixed at 60°C for 45 minutes, soaked for 70 minutes; post-dyeing treatment, wash the fixed yarn in cold water for 9 minutes, use acetic acid for reduction cleaning at 60°C for 9 minutes, and then wash in cold water for 9 minutes Finally, soaping is carried out three times at 97°C for 15 minutes, after adding a color-fixing agent, the temperature is raised to 30°C for 9 minutes, and after adding a softener, soak for 35 minutes to complete the dyeing.

Embodiment 3

[0026] This example provides a water-saving dyeing process for cheese, including yarn pretreatment, dyeing and post-dyeing treatment; yarn pretreatment: add refining agent in water at 90°C, boil the yarn for 30 minutes, wash in cold water for 7 Minutes; Dyeing: including three stages of adsorption, diffusion and fixation in sequence, adding dyes to yarn dyeing for 15 minutes in the adsorption stage, adding neutral electrolyte to promote dyeing for 3 minutes in the diffusion stage, using 15g / Soda ash is fixed at 55°C for 40 minutes, soaked for 60 minutes; post-dyeing treatment, wash the fixed yarn in cold water for 7 minutes, use acetic acid for reduction cleaning at 50°C for 7 minutes, and then wash in cold water for 7 minutes Finally, soap at least once at 95°C for 10 minutes, add a color-fixing agent and heat up to 28°C for 7 minutes, add a softener and soak for 30 minutes to complete the dyeing.

Abstract

The invention provides a water-saving dyeing process of cheese, and the cheese is dyed by yarn pretreatment, dyeing and dyeing postprocessing. According to the water-saving dyeing process of the cheese, a refining agent is chosen to replace caustic soda and hydrogen peroxide of a traditional process for the yarn pretreatment, and the refining agent can ensure that yarn is soft in hand feeling, is unconspicuous in inner and outer-layer color difference, and is basically free of reparation and broken end phenomenon, a woven fabric is smooth, the weight loss rate is reduced to about 3%, acid pickling is not needed, the time is short, and is shortened by 30 minutes to 1 hours compared with that of the traditional process, so that the water, electricity and time are saved, the bleaching consumption is low, the dyeing quality is good, and the comprehensive cost is low. At the same time, in the water-saving dyeing process of the cheese, a neutral electrolyte is added for accelerating the dying in a diffusion stage, the dye uptake of the cheese is ensured, and the problems of dyeing defects, deep and shallow strips, great inner and outer-layer difference and the like can be avoided.

Description

technical field [0001] The invention relates to a dyeing process, in particular to a water-saving dyeing process for cheese. Background technique [0002] The traditional pretreatment process of cotton, linen and their blended cheese is the oxygen bleaching process using caustic soda, hydrogen peroxide and other additives. Due to the high pH value, many types of additives, and long reaction time, the weight loss rate of the yarn is caused by this process. High, the fiber is damaged and becomes brittle, the strength is reduced, the hand feels rough, the water consumption is large, the process time is long, and the energy consumption is high. Due to the thick yarn layer, the alkali absorption is uneven, it is difficult to wash, and the dyeing is prone to dyeing with color difference between the inner and outer layers. Defects, especially when bleaching blended products, caustic soda will cause damage to another fiber, which will affect the smooth progress of dyeing. [000...
