Description

The present invention relates to the field of textiles, and in particular to dyeing and finishing processes for textiles and textiles.

With the improvement of people's living standards, consumers are increasingly demanding comfort, hygiene and other multi-functionality of household textiles, and it is expected that textiles will have deodorizing and deodorizing functions. has been done.

In order to give textiles deodorizing and deodorizing functions, deodorizing fibers are usually used as textile raw materials, and the deodorizing principle of conventional deodorant fibers is realized by modifying the fibers, By introducing such groups into the molecular chain of the fiber, the fiber has a deodorizing function. The presence of functional groups changes the properties of the fiber itself, the presence of deodorizing function is due to the functional groups, and when the fibers are spun into fabric using normal dye finishing processes, the color fastness and durability change. Not only does it affect washability, but it can also cause the functional groups to fall off and become ineffective, thus new directional dye finishing methods are needed.

The technical problem to be solved by the present invention is to provide a method for dyeing and finishing deodorizing fiber fabrics, in which the dyeing process is carried out in stages, various dyeing aids are added in stages, and the dyeing process is carried out in stages. Conventional technology that reduces the damage to deodorizing groups of fibers caused by alkaline dyeing agents as much as possible, and that the actual deodorizing properties of deodorizing fiber fabrics are significantly reduced after dyeing with strong alkaline dyeing alkaline agents. resolve the defects.

The invention is implemented as follows. A method for dyeing and finishing deodorizing textile fabrics, which uses soda ash as an alkaline agent for dyeing, divides the alkaline agent for dyeing into two parts,

Example A method for dyeing and finishing deodorant textile fabrics, using soda ash as the dyeing alkali agent, dividing the dyeing alkali agent into two parts, and comprising the following steps.

First, a bleaching pretreatment including steps preS1 to preS3 is performed.

Or add hydrogen peroxide solution to adjust the pH value of the bleaching solution to 9-9.5, where the amount of hydrogen peroxide used does not exceed 2g/L, and the amount of hydrogen peroxide used is high. If too much, the deodorizing group is likely to be damaged during the bleaching pretreatment step preS1.

Step preS2 of kearing at 70-80°C for 50-100 min.

Firstly, hot washing with water at 50-60°C for 10-20 minutes, then washing with clean water at room temperature, further washing with 0.1-1 g/L glacial acetic acid aqueous solution, and finally washing with ice water with water. Step preS3 of washing and removing acetic acid to obtain a fabric to be treated.

In the present invention, the bath liquid is generally ordinary tap water, and in addition to ensuring that the fabric to be treated is sufficiently soaked at this stage, it is also necessary to take into account the high hardness of tap water in certain regions. In order to avoid metal ions in the water from damaging the fabric and affecting the dyeing effect, the hardness of the bath liquid should also be detected in this step, and based on the detection results, the complexing agent is added to reduce the hardness of the bath liquid to 100 ppm or less.

In steps S2 and S3, the dye, the protective aid, the alkaline agent for dyeing in the first part, and the alkali agent for dyeing in the second part are added stepwise at fixed time intervals so that the fibers having deodorizing groups are dyed. This is because the dyeing process may be affected by the alkaline dye, which reduces the deodorizing properties of the final fabric. Therefore, the dyeing alkaline agent is divided into two parts, and only Na ₂ CO ₃ sodium carbonate (soda ash) of the weak alkalis is used as the dyeing alkaline agent, and the use of stronger alkalis is prohibited. Firstly, the textile material is pretreated with a protective aid at a lower temperature and partially dyed to form a certain protective layer, and then the fabric is completely dyed at a second temperature and a second part with a dyeing alkaline agent. dyeing process to eliminate the influence of the dyeing process on deodorizing properties. In this process, the protective aid not only promotes coloration of the dye and improves color fastness, but also plays a role in protecting the base color of the deodorizing fiber.

In the present invention, preferably, in mass percentage, the alkaline dyeing agent in the first part accounts for 25% to 40% of the total content of the alkaline dyeing agent, and the alkaline dyeing agent in the second part accounts for 25% to 40% of the total content of the alkaline dyeing agent. The specific method of adding the dye, the protective aid, and the alkaline agent for dyeing in the first part in stages is at intervals of 10 to 20 minutes after adding the dye, which accounts for 75% to 60% of the total content of the dye. The first step is to add the protective aid and then add the first dyeing alkali agent at intervals of 10 to 20 minutes. The first temperature is 30~45°C, the first time is 5~15min, the second temperature is 55~70°C, the second time is 5~15min, and the third time is 50~60min. The first temperature increase rate is 0.5 to 2° C./min, and the pH is maintained at 10 to 10.5 within the third period.

In addition, when setting the bath ratio of the fabric to be dyed and the dyeing solution, it can be selected according to the actual situation. Set it high and set the dark color bath ratio low.

In the specific implementation, as described in the present invention, preferably, the protection aid is anhydrous sodium sulfate (sodium sulfate Na ₂ SO ₄ powder, commercially available common product), and the amount added is the same as that of the protection aid.
