What is the Union-Dye Effect

Solid Effect or Union-Dye Effect refers to two fiber-dyed hue or hue, and the color of the color is similar or the color is close, and the color is bright. If it is represented by color feature values, the effect of the same color means that the brightness or brightness L of the two fibers is similar, the red and green index A and the yellowish and blue index B are similar, the color phase angle H is similar, the color C is similar, the reflection is reflected, the reflection is reflected The spectrum curve and maximum absorption wavelength λmax are similar and the value of the color of the color is similar.

Union-Dye Effect is a dyeing method with dual -component fibrous textiles. It is especially true for those dual -component fibrous textiles developed by the purpose of reducing the cost of reducing raw materials, improving durability and improving the physical properties of fabrics.

The difficulty of Union-Dye Effect is very different due to the different combination of fiber. The fiber combination with close dyeing performance is easier to dye the same color; the fiber combination with a particularly large difference in dyeing performance, as long as the two fibers are dyed separately, the same color problems can be solved by color. Small or dipsticks are easy to remove, and the same color dyeing is relatively easy.

The most difficult thing for Union-Dye Effect is the dual fiber textiles, although the dyeing temperature can be adjusted by the dyeing temperature and the addition of the dyeing carrier. The amount of upper staining on the two fibers, but this adjustment has a certain limit. Of course, for polyester/nylon or acrylic blended products, the nylon or acrylic can be adjusted to the same color with acidic or cationic dyes respectively. For the same color staining of the intertwined products of acetaceae/polyester, if it is dyed deep, the acetaceous fiber is easily damaged under harsh dyeing conditions. Therefore, the dark color, one bath method is not very feasible.

It is easier to obtain dual -group fibrous textile products with the Union-Dye effect, such as nylon, polyester or acrylic blended products such as nylon or dyeing dye dyeing dyeing dyeing dyeing dyeing products. Small, so it is easy to get the same color through color matching, and the dyeing is also good.

The differences in the luster and light transmission rate of each component fiber in dual -component fiber textiles often affect the Union-Dye Effect, such as the fiber/wool blending product.
