Test experiment:

 

1. Put the combined sample into a specified airtight container, and put the washing test solution in the container with a mass ratio of 50:1 to the combined sample;

 

2. Rotate the sealed container along a radius of 45mm and a speed of 40r/min, and perform mechanical stirring at the specified temperature and time;

 

3. Take out the sample at the end of the test, wash it twice with cold third-grade water, then rinse it in running cold water for 10 minutes, and squeeze out the water;

 

4. Unfold the combined sample so that the sample and the lining are only connected by a suture, and hang it in an environment not higher than 60°C to dry;

 

5. Use the gray sample card for discoloration to evaluate the discoloration of the sample, and use the gray sample card for staining to evaluate the staining of the lining fabric.
