Test method for water absorption of cloth towels

The water absorption of cloth towels is one of the important indicators to measure their quality. The following are several common methods for testing the water absorption of cloth towels:

1. Fabric water absorption tester method
This method is suitable for testing the liquid absorbency of non-woven fabrics or non-woven fabric materials under constant pressure. The specific steps are as follows:
1. Place the sample on a special porous plate, which is connected to the reservoir through a siphon, and the liquid level is lower than the upper surface of the porous plate.
2. Obtain the pressure absorbency of the fabric by measuring the change of the mass of the reservoir over time.
3. Use an electronic balance and porous plate flow rate calibration to ensure the accuracy of the test.

2. Static and dynamic measurement mode
This method is particularly suitable for testing absorbent products such as sanitary napkins, but can also be applied to cloth towels. The specific steps are as follows:
1. Adjust the detection device to static measurement mode and place it on the horizontal plate to test the water absorption of cloth towels in static conditions.
2. Adjust the detection device to dynamic measurement mode and install it in dynamic mode to simulate the water absorption test of cloth towels in use.
3. This method can provide more realistic water absorption results and has a higher reference value.

3. Natural water absorption test
This method evaluates the water absorption of a cloth by measuring its water absorption capacity in a natural state. The specific steps are as follows:
1. Immerse the cloth completely in water to fully absorb water.
2. Take out the cloth and gently squeeze it to remove excess water.
3. Weigh the cloth after absorbing water and compare it with the weight when dry to calculate the water absorption rate.

4. Saturated water absorption test
This method evaluates the water absorption of a cloth by measuring its water absorption capacity in a saturated state. The specific steps are as follows:
1. Immerse the cloth completely in water to saturate it.
2. Take out the cloth and gently squeeze it to remove excess water.
3. Weigh the weight of the cloth after saturated water absorption and compare it with the weight when dry to calculate the saturated water absorption rate.

Conclusion
There are many methods for testing the water absorption of cloth, and you can choose the appropriate method according to your specific needs. Through these test methods, the water absorption performance of cloth towels can be accurately evaluated, thus helping consumers choose high-quality products.
