hot wire! Biological buffer can be used in fabric dyeing

Release time:


As the solution that must be used in various experiments, biological buffer has many types, such as Tris, Mops, Caps, and so on. Their role cannot be underestimated, so they will be widely used in various fields, such as biochemical experiments and diagnostic tests. In addition, recent studies have shown that buffer solutions can also be used in dyeing fabrics, so we will give you a detailed analysis of their role in fabric dyeing.

Due to the sensitivity to pH in the process of cloth rendering, color deviation or color mixing may occur once the pH value is not properly controlled. To prevent this phenomenon, it is necessary to add a proper amount of buffer solution to the dye solution for adjustment, so as to maintain the pH stability of the dye solution.

1Reasons for using buffer to adjust acidity and alkalinity

1. Improper pre-treatment of the fabric without cleaning will cause a small amount of acid or alkaline substances to be brought into the dye and change the original acidity and alkalinity.

2. Other substances are sometimes added during the production process. These substances are not neutral, which will affect the whole acid and alkali environment.

3. Some materials may have high or low acidity and alkalinity. If they are dyed, they will react directly. For example, the acidity and alkalinity in the process of disperse dyes is 8 or 10. But when the boiler supplies gas, there will sometimes be negative pressure. The acid or alkali solution in other containers may be poured into the pipeline, which will change when the dye tank is heated.

2Effect of buffer on dyed fabrics

In order to maintain the color of the fabric to a bright degree, it is necessary to ensure that the acidity and alkalinity are within a reasonable range. Generally, the color obtained only by operation in a weak acid dye tank is relatively pure. At this time, it can be controlled in the weak acid range by adding acetic acid buffer.

In addition, the acidity and alkalinity required in some wool dyeing are more strict, and different buffers need to be used to clearly control the acidity and alkalinity in the operation process, which can effectively help improve the depth of dyeing and improve the dyeing efficiency to a certain extent.
