Today, Xiaobian will tell you about the impact of color fastness on the quality of webbing. Color fastness is the most important goal of good quality and badness of webbing. The most important thing is the color fastness conflict resistance, perspiration resistance, water wash resistance, light resistance and rinsing resistance.
The various kinds of delicate webbings that are usually seen in the production process have to pass through multiple webbing processes. In the process, the webbing is usually different from batches due to various reasons such as material, production process and operation. Even the same batch of fabric will have a difference in color. The difference in the color of the fabric, if the color source is not the same, the color environment, the color time is not the same, the evaluation of the color difference is not the same. Therefore, in order to accurately evaluate the difference of colors and ensure the consistency of color results, in visually identifying colors, it is necessary to select the source color specified by the merchant in the standard color light box to prevent the vision from being caused by the non-standard light source or the light source. The difference.
Color fastness is the most important goal of the quality of the webbing. The first priority is the color fastness, the seizure resistance, the perspiration resistance, the water repellency, the light resistance and the rinsing resistance. First of all, according to the usefulness of the goods, the projects are checked and the special requirements are made according to the needs. The problem of producing a decolorized webbing at the webbing factory can be large or small. If the webbing used for clothing accessories is discolored during washing, the whole piece of clothes, or the clothes washed together, will be contaminated at the same time. The discolored ribbon will give a very serious disgust.
The so-called color fastness refers to the degree to which the dyed textiles adhere to the color under the physical and chemical effects, that is, the color of the dyed textile is affected by the external influence, which is called the color fastness. The color change of the sample after the experiment indicates the color fastness of the white cloth.
Among the various items of color fastness, the most commonly used color fastnesses are color fastness to conflict, color fastness to perspiration, color fastness to washing, light fastness to light, color fastness to water immersion, and color fastness to washing. Degree, weather fastness and other items. In actual life, it is decided to check the items based on the final use of the goods. Among them, the perspiration-resistant, dry-resistant, and water-resistant color fastness are the items of textile safety technical specifications. All dyed textiles should be checked. In addition, regarding the baby textile products, check the color fastness to saliva.
The identification of color fastness is usually based on the visual identification method, that is, the gray sample card is used as the standard sample, and the gray light and the sample are compared with the human eye under certain illumination and environmental conditions to determine the original color change of the sample and the white cloth staining level. number. Gray cards (discoloration and staining, respectively) are five fastness grades, namely 5, 4, 3, 2, 1. 5 is the best, and 1 is the worst. In each of the two grades, the half grades are compensated, that is, 45, 34, 23, and 12, so the gray card we use for daily use is grade 5 and grade 9, and the color fastness identification results are one of the nine grades. If the color fastness of a webbing product does not reach the level of the normative rule, the webbing product is unqualified.
