It is found that the color fastness of conventional color is slightly higher than that of fluorescent color in the application of color fastness to sunlight. For people in the clothing industry, it is necessary to
To more thoroughly grasp the important standard of color fastness of fluorescent fabric and some matters needing attention, to avoid business mistakes due to color fastness
It leads to economic losses.
Selection of dyes
The selection of dyes has a very important impact on the color fastness of clothing. If the dye is not selected properly, even if the best auxiliaries and dyes are used
It is impossible to make products with high performance and color fastness by using different dyeing processes. Therefore, only by choosing the right fuel can we proceed to the next step.
The choice of different fuels leads to different color fastness. The types of dyes are subdivided as follows:
Acid fuel is more soluble in water and is widely used in protein, nylon fiber and silk. It is specific to have a bright color, but washed
The color fastness after dry cleaning is poor, and the color fastness of dry cleaning is better, so it is often used in natural dyeing.
It is also characterized by bright colors. It is mostly used for acrylic, polyester, nylon, cellulose and other man-made fibers and protein fibers, but in some areas
The color fastness of natural cellulose and protein textiles is very poor.
This kind of dye can be directly dyed in all kinds of cellulose textiles without any other reagents, and its color fastness is different due to its different use environment
And the color fastness to washing can be greatly improved by changing his characteristics.
The characteristic of the dye is that it is not easy to dissolve in water and the particle size is very fine. It is mainly used for viscose, acrylic, nylon, polyester, etc., mainly dyeing polyester fabrics
. It has bright color, excellent washing fastness and wide application.
It is a kind of synthetic fuel for printing and dyeing of various synthetic fibers. It is also one of the most widely used fuels in garment processing
Brilliant colors and bright colors are often used in cellulose fabrics.
Reactive dyes are a new type of water-soluble fuel, because some of the active molecules are easy to interact with some of the active molecules in cellulose and protein fibers
Chemical reaction, the formation of covalent bonds, namely "dye fiber" compounds. Therefore, the fuel is mostly used in cellulose fiber fabrics, not in protein materials. it
It has many advantages, such as bright color, good color fastness to water light and rubbing resistance.
This is a kind of dye that is reduced and colored under certain conditions such as alkalinity, and then oxidized to return to the original insoluble dye
It is used in cellulose fiber; It also has good color fastness to light and washing.
Therefore, according to the characteristics of the fiber itself and the dye color fastness level, type and color depth, as well as dye dyeing rate and other factors, to correct
It is necessary to match the combination of dyes and fibers to reduce the impact of fluorescent fabrics on color fastness.
The fluorescent fabric produced by Xinxiang Yulong Textile Co., Ltd. can reach the standard of en20471 and the color fastness can reach grade 4. In addition, resistance can be added
Flame retardant fabric has two functions: fluorescent fabric and flame retardant fabric, and each function does not affect each other, which can achieve their own functional protection effect
The flame retardancy can reach en11612 (original en531), en11611 (original en470-1) and en533 of European Union; NFPA 2112 of the United States
ASTM and other standards, suitable for a variety of complex environments.
