diaper testing process

1. Raw material testing: Testing the main materials of the diaper, including the quality and material of the absorption layer, surface layer, and backsheet. 

2. Dimension measurement: Measuring the size of the diaper, including waist circumference, leg circumference, and length, to ensure it meets the standard size requirements. 

3. Absorption performance testing: Pouring a certain amount of liquid into the diaper to measure its absorption speed and quantity, evaluating its absorption performance. 

4. Leakage performance testing: Using simulated urine for testing, evaluating the diaper's leakage performance, including side leakage and back leakage. 

5. Elastic band performance testing: Testing the stretch and resilience of the diaper's elastic band to ensure proper comfort and fixation. 

6. Basic appearance inspection: Checking the appearance of the diaper, including smoothness and absence of obvious defects. 

7. Safety testing: Testing whether the diaper contains harmful chemicals, such as heavy metals and harmful dyes, to ensure user safety. 8. Wearability evaluation: Inviting users to try on the diaper and collecting their feedback and reviews to enhance product comfort and usability.
