Bought new After the clothes When I went through the water several times, I found that the clothes had shrunk, were tight to the body, and were not comfortable to wear at first, which affected the feeling of wearing the clothes. The problem of clothing shrinkage is a problem that every clothing company will encounter. Therefore, before the clothes leave the factory, they should conduct random inspections of the clothes shrinkage rate test, which is an indispensable part of the quality inspection of clothes.
Test scheme:
1. Prepare the Shrinkage Rate Testing Machine, the Shrinkage Rate Oven, the Shrinkage Rate Pressure Ruler.
2. Prepare Provide several clothing samples for testing and measure the size of each sample with a shrink pressure ruler and record the data.
3. Put the sample into the shrinkage testing machine and set it to water temperature , testing time , Start the test machine until the program is finished, take a sample.
4. Place the sample in a shrink oven to dry.
5. Print out the shrinkage rate of the dried sample to measure the size, compare with the previous data and calculate the difference between the two, then you can get the shrinkage rate value of the clothes.
