Effect Of Color Fastness On Webbing

- Feb 23, 2019-

Color fastness is the most important goal of the quality and badness of the webbing. The most important thing is the color fastness, the anti-collision, the perspiration resistance, the water wash resistance, the light resistance and the rinsing resistance.

The various kinds of delicate webbings that are usually seen in the production process have to pass through multiple elastic belt processes. In the process, the webbing is usually different from batches due to various reasons such as materials, production processes, operations and the like. Even the same batch of fabric will have a difference in color. The difference between the color of the fabric, if the color source is different, the color environment, the color timing is different, the evaluation of the color difference is also different. 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 ribbon of good quality and badness of the webbing. The primary importance is the conflict resistance of color fastness, perspiration resistance, water wash resistance, light resistance and rinsing resistance. The first priority is to check the items based on the usefulness of the goods and to make them special 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. Decolorized webbing can be very distasteful.

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 fastness 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-friction-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 color fastness is usually identified by visual identification method, that is, the gray sample card is used as the standard sample. Under the certain illumination and environmental conditions, the gray light and the sample are compared with the human eye to judge 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 grade is compensated, that is, 4 5, 3 4, 2 3, and 1 2, so the gray card we use for daily use is 5 grade 9 grade, and the color fastness identification result is one of 9 grades. If the color fastness of a webbing product does not reach the level of the normative rule, the webbing product is unqualified.
