What is the effect of color fastness on the quality of ribbon

Grandlink believes that color fastness is the most important target of good or bad quality of ribbon, and the first priority is the conflict resistance, sweat stain resistance, water resistance, light resistance and washing resistance of color fastness.

　　Usually see all kinds of exquisite ribbon in the production process to pass through a number of elastic process, in this process, because of the material, production process, operation and other reasons caused by the error, usually not the same batch of ribbon, or even the same batch of cloth in the color will be different. The size that cloth colour differs, if be opposite, of lubricious illuminant different, to lubricious environment, to lubricious moment different, also different to the evaluation of chromatic aberration. Therefore, in order to accurately evaluate the color difference and ensure the consistency of color result, it is necessary to select the light source specified by merchants in the standard color light box for color identification, so as to prevent the visual difference caused by non-standard or different light sources.

　　Color fastness is the quality of good and bad ribbon ribbon is the most important goal, the first priority is the color fastness of conflict resistance, resistance to sweat stains, water resistance, light resistance, washing resistance. Those items are identified primarily on the basis of the use of the commodity and are tailor-made on demand. The problem of bleached ribbon produced by the ribbon factory can be large or small. If the ribbon used for clothing accessories is bleached in water, the whole garment or the clothes washed together will be contaminated at the same time. Discoloration of the ribbon will give a very serious sense of disgust.

　　The so-called color fastness refers to the degree to which the color of dyed textiles adheres to the fastness under physical and chemical effects, that is, the degree to which the color of dyed textiles is subject to external influences is called the color fastness. The color fastness of the white cloth was determined by the color change of the sample and the degree of color stain.

　　In various color fastness projects, the current commonly used color fastness include color fastness to conflicts, color fastness to perspiration, color fastness to washing, color fastness to light, color fastness to water immersion, color fastness to washing, color fastness to climate, etc. In real life, the primary basis for the ultimate use of commodities to determine which items, including resistance to sweat stains, dry abrasion, water immersion color fastness is the fundamental safety technical specification requirements of textiles, all dyed textiles should be checked. In addition, for infant textile products also checked saliva color fastness.

　　The identification of color fastness usually choose visual identification method, that is to take the gray sample card as the standard sample, under certain lighting and environmental conditions, the eye of the human comparison of gray card and sample, in order to determine the original sample discoloration and white cloth stained series. The grey card (discoloration and stain respectively) has five fastness grades, namely 5, 4, 3, 2 and 1. Level 5 is better and level 1 is worse. Half grade is made up in every two grades, namely 4, 5, 3, 4, 2, 3, 1, 2. Therefore, the grey card we use in daily life is grade 5 and grade 9, and the result of dyeing fastness identification is one of 9 grades. If the ribbon of a certain item of color fastness does not meet the standard rules of the grade, then the ribbon of goods for unqualified.
