With the continuous progress of modern life, people's demand for personalization is increasing day by day. Some personalized features and packaging in our life all come from the collocation of colors. This includes our clothes, curtains at home, scenery, walls and so on. It can be said that all aspects are inseparable from color, and further, it should be said that it is inseparable from dyes. This paper analyzes the prices of dyes for different purposes, aiming at enabling us to better select dyes for different purposes. Choose products with high cost performance.

We say that the price of dyes varies according to their uses. Let's do an analysis.

According to different fiber properties, when we choose dyes, we should choose the right dyes. To give a few examples: when we need to dye cotton fiber, considering its easy moisture absorption and expansion, it often reacts with reactive groups. Another feature of it is its alkali resistance, so it is dyed with vulcanizable, ice-dyed and reactive dyes. Polyester is characterized by strong hydrophobicity and alkali resistance at high temperature, so disperse dyes can be selected for dyeing. Generally, the unit price of these disperse dyes ranges from 60-80 yuan.

The fastness requirements of dyed products vary greatly due to the different uses of dyed products. For example, the number of times curtain cloth is washed is quite small. But the sun exposure time is long, so it is very important to choose dyes with high light fastness when dyeing. For example, underwear and light-colored fabrics worn in summer are often washed or dried. Therefore, we should choose dyes that are washable and sunfast and have high perspiration fastness. Generally, the unit price of curtain dyes on the market is between 40-60 yuan.

Generally speaking, the selection of dyes should not only be considered from practical aspects, but also the dye itself, related costs and the supply of additives. We say that the higher-priced dyes are replaced by dyes with the same dyeing effect, thus reducing the cost.

When choosing dyes for color matching, we should pay attention to their composition, solubility, color fastness and dye uptake. Different properties of various dyes will cause dyeing problems, including differences in temperature, solubility and dye uptake. Therefore, we should choose dyes with similar quality when matching colors. In this case, we are conducive to the control of process conditions and the stability of dyeing quality.

Different dyeing machines have different properties and requirements for dyes. Dyes with high directness should be used in jig dyeing; Pad dyeing requires low directness of dyes. If the dye is not selected correctly, there will be defects such as deep before and shallow after. Pad dyeing prices in the market range from 30 to 50 yuan. In addition, the prices in the market are quite different, which is also related to their own materials.

Above, we made an evaluation of the price through the different uses of dyes. Due to the different materials of true and false dyes in the market, the price of dyes is also very different. However, we should also pay attention to what we have paid for.
