Standard for Color Fastness Test of Microfiber Leather

Standard for Color Fastness Test of Microfiber Leather

In the production process, after the dyeing process, whether the color fastness of the microfiber leather meets the standard needs to be tested, and only after the test is qualified can it be put into the market. Generally speaking, the detection of color fastness requires three aspects of detection. Only after the three different tests are qualified can the color fastness standards be truly achieved. What are the specific contents of the three tests for color fastness? Let's take a look together below.

　　1. The color fastness to acid and alkali perspiration of microfiber leather: the color fastness to acid and alkali perspiration is implemented according to GB/T3922. Laminate the textile sample with one or two specified lining fabrics, put them in acidic and alkaline simulated sweat respectively, remove the test solution, and place them in the middle of the two flat plates of the test device to withstand the specified pressure. The dry sample and the lining fabric are used to evaluate the discoloration of the sample and the staining of the lining fabric with a gray scale.

　　2. Color fastness to saliva: The color fastness to saliva is implemented according to GB/T18886. Lay the textile sample with one or two specified lining fabrics, treat it in artificial saliva, remove the test solution, and place it in the middle of the two plates of the test device to withstand the specified pressure. The dry sample and the lining fabric are used to evaluate the discoloration of the sample and the staining of the lining fabric with a gray scale.

　　3. Color fastness to dry and wet rubbing: The color fastness to dry and wet rubbing is implemented in accordance with GB/T3920. The samples were rubbed with dry and wet rubbing cloth respectively, and the staining of the rubbing cloth was evaluated with a gray scale.

　　 The color fastness of microfiber leather is generally tested in the above three aspects. As long as it meets the standards in dry and wet resistance, acid and alkali resistance and saliva resistance, it is a microfiber leather product with qualified color fastness.
