JIS test standard color dyeing fastness tester to rubbing

JIS (Japanese Industrial Standard) has multiple related test standards for testing the rubbing fastness of color dyeing. The following is a commonly used JIS test standard:


JIS K 6833: This standard specifies methods for evaluating the durability of colored dyes on fabrics during rubbing. It involves testing a sample in contact with a standard friction material and rubbing it, and then observing the degree of discoloration of the colored dye.


The JIS K 6833 testing process is briefly introduced as follows:

1. Sample preparation: Prepare a test sample, usually a fabric, ensuring that it meets the dimensions and requirements specified in the standard. Samples are usually dyed to evaluate the dye's durability in rubbing.


2. Set up the instrument: Set up the color dyeing rubbing fastness tester according to the requirements of the standard. This may include selecting the appropriate friction head, adjusting the friction speed and number of frictions, etc.


3. Carry out the test: put the sample in contact with the standard friction material and carry out the predetermined friction process. Generally speaking, friction will be carried out under specific conditions, such as a certain number of frictions, a certain friction speed and a certain friction force.


4. Observation and evaluation: After the rubbing test is completed, observe the degree of discoloration of the colored dyes on the sample. Color changes are evaluated and recorded according to a rating system specified in the standard.


JIS K 6833 is a common test standard for evaluating the durability of color dyes during rubbing. This standard helps to measure the quality and durability of fabric dyeing to ensure that it has good durability and color stability in actual use. Please note that this is just one of the JIS test standards, there are other related test standards available for different materials and application areas.
