Problems solved by technology

Because the optimal temperature of the enzyme is relatively low, and it is very sensitive to the pH value, it is difficult to achieve the ideal treatment effect in the enzyme oxygen bath
[0004] The process of enzymatic oxygen one bath has been researched and explored in the pre-dyeing process of cotton fabrics, such as patent 2012103181847 and patent 2012104868245, but the above-mentioned technologies are all for direct treatment of fibers or fabrics, and have not yet been involved in cotton cheese Due to the unstable effect of enzyme oxygen one-bath treatment and the high requirements for the capillary effect and whiteness of yarn in pre-treatment of cheese, the above-mentioned pre-treatment technology for fibers or fabrics cannot be applied to the pre-treatment of cotton cheese, so now The pre-dyeing process of cotton cheese still uses the traditional alkali scouring process. Therefore, it is necessary to explore the application of the enzyme-oxygen one-bath process in the pre-dyeing field of cotton cheese

Embodiment 1

[0026] Embodiment 1: the pretreatment effect of different formulation pretreatment agents

[0027] The pretreatment agent is one of the most basic factors affecting the treatment effect. In this example, under the conditions of pH 8, bath ratio 10:1, heating rate 2°C / min, treatment temperature 55°C, and treatment time 50min, the pretreatment of different formulations The treatment agent was tested, and the formulation of the pretreatment agent and the comparison of treatment effects are shown in Table 1.

[0031]

[0032] Hydrogen peroxide and biological enzymes are the main active components of pretreatment. In this embodiment, hydrogen peroxide is mainly used for bleaching. When the content of hydrogen peroxide is low, the treatment effect is not good due to insufficient dosage, which is specifically reflected when the amount of hydrogen pe...

Embodiment 2

[0037] Embodiment 2: the impact of different pretreatment conditions on the treatment effect

[0038] The pre-treatment process is also a key factor affecting the treatment effect. In this embodiment, under the conditions of 30% hydrogen peroxide 4g / L, biological enzyme 6g / L, hydrogen peroxide active agent 3g / L, and penetrant 2g / L, the different treatment conditions The treatment effect was tested, and the pretreatment conditions and treatment effect comparison are shown in Table 2.

[0041]

[0042] In the pretreatment process, pH and treatment temperature are the biggest differences between this application and the conventional alkali scouring process, because under the pretreatment agent atmosphere of this application, the optimum pH value of biological enzymes is close to neutral and hydrogen peroxide The effect is more obvious under alkaline conditions, etc. When the pH value is ...

Embodiment 3

[0046] This embodiment is used for the pre-treatment method of cotton cheese dyeing, which is formed by the combination of treatment agent formula, pH value of treatment solution, and treatment process parameters, wherein:

[0047] (1) The pretreatment agent is: 30% hydrogen peroxide 4g / L, biological enzyme 6g / L, hydrogen peroxide active agent 2g / L, osmotic agent 1g / L; the pH value is adjusted to 8, and the bath ratio is 10:1.

[0048] (2) Process parameters: at room temperature, the temperature is raised to the treatment temperature at 2°C / min, the treatment temperature is 50°C, and the treatment time is 60 minutes.

Abstract

The invention relates to a pretreatment agent and a method for using the pretreatment agent for dyeing pretreatment of cotton cheese yarns, and belongs to the technical field of biochemical treatment of fibers, yarns, threads, fabrics or fibrous products made of the raw materials. The method comprises the following steps: using bio-enzyme, hydrogen peroxide, a hydrogen peroxide activator and an additive for dyeing pretreatment, wherein the contents of the added components are as follows: 4-12 g / L of 30% hydrogen peroxide, 5-10 g / L of bio-enzyme, 1-3 g / L of hydrogen peroxide activator and 1-3 g / L of a permeating agent; adjusting a pH value to 7-9 at a bath ratio ranging from (5:1) to (20:1); heating to a treatment temperature at 2 DEG C / min at room temperature, wherein the treatment temperature is 50-65 DEG C, and the treatment time is 40-60 min. The method is applied to the dyeing treatment of cheese yarns, and can not only reduce the treatment temperature and the pH value of hydrogen peroxide and solve energy consumption problem caused by high temperature, pollution of treatment waste liquid to environment caused by strong alkali and other problems, but also shorten process flow, improve production efficiency and achieve a satisfactory treatment effect.

Description

technical field [0001] The invention relates to a pretreatment agent and a method for using the pretreatment as a low-temperature pretreatment of cotton cheese in an enzyme-oxygen bath, and belongs to the technical field of biochemical treatment of fibers, yarns, threads, fabrics or fiber products made of these raw materials. Background technique [0002] The printing and dyeing industry is a key industry in the textile industry chain to increase the added value of products, but there are often problems such as energy consumption, high water consumption, and pollutant discharge in the production process of enterprises. With the rapid development of the textile printing and dyeing industry, environmental protection issues are becoming more and more serious. protrude. Research on printing and dyeing technology should link pollution control with the production process, and develop new technology that can make full use of raw materials, energy and resources and reduce pollutant ...
