"Water Absorption of Clothing Materials" PPT Courseware 3

Sweat, rain... in many cases will make your clothes wet. What are the water absorbencies of different clothing materials? What factors are related to the water absorption of clothing materials?

Question→Hypothesis→Experimental method and process→Conclusion

Our questions:

1. What is the water absorption of different clothing materials?

2. What factors are related to the water absorption of clothing materials?

Our speculation:

1. Different clothing materials may have different water absorption properties.

2. The water absorption of clothing may be related to the material, thickness, softness and hardness of the clothing.

Research result:

This experiment shows that different clothing materials have different water absorption; the water absorption of clothing materials is related to factors such as the material, hardness, and thickness of the clothing materials.

Highly absorbent material

In the past, when people talked about highly absorbent substances, they would immediately think of sponges because they can absorb water several times its own weight. However, the highly water-absorbent materials seen on the market in recent years can absorb hundreds or even thousands of times of water equivalent to their own weight. Moreover, after absorbing water and swelling, it is difficult to squeeze out the water even if pressurized, such as a piece of baby The "diapers" used in diapers still do not leak even if they absorb 1,000 ml of water, and they also maintain good ventilation.
