What is the standard level of color difference in anti-static overalls?
There will be a certain color difference between the sample and the newly purchased anti-static overalls. This is mainly because the fabric is not dyed in the same batch of the same dyeing tank, and the color difference will be correspondingly produced.
The color difference problem is often encountered when customizing work clothes. When purchasing a batch of anti-static clothes, customers like to compare their samples with the purchased samples, such as workmanship, color and other details. Take the color of the fabric of the anti-static overalls. There will be a certain color difference between the sample clothes and the newly purchased clothes fabrics. This is mainly because the cloth is not dyed in the same batch of the same dyeing tank, and the color difference will be correspondingly produced. Although everyone is avoiding as much as possible, sometimes it can't be avoided.
According to the national standards for the color difference, the upper collar of the garment, the fabric of the bag, and the side seam of the trousers are the main parts, the color difference is higher than the fourth grade, and the other surface parts are four grades. For the color difference test of electrostatic clothing, the tool is to use the "dye fastness fading sample card". The sample card is one of the national standards established by the former Ministry of Textile Industry. The sample card consists of five pairs of gray standards and is divided into five levels. The five-level representative has good fading fastness, the color difference is equal to zero, and the fourth-level to the first-level represents the relative increase of fading, and the first level is more serious.
