The following steps are required to test the water absorption of adult diapers:

(1) Prepare a bottle of 1500-2000ml water;

(2) Unfold the adult diapers and lay them on the test bench;

(3) Slowly pour the water onto the unfolded diapers until the water in the bottle is exhausted.

(4) Pour water once to observe the water absorption effect of the diaper. The more water is absorbed, the better the water absorption performance of the diaper.

Of course, the water absorption of diapers depends not only on the amount of inhalation, but also on whether reverse osmosis will occur. Because reverse osmosis refers to that after the diapers absorb urine, some urine will leak out under pressure, thus affecting the skin comfort and even causing skin diseases to users in the long run. Therefore, small or no reverse osmosis is an essential element of a high-quality diaper. As for the reverse osmosis test, the editor also summarized the following points:

(1) Prepare a cup and fill it with proper amount of water;

(2) Pour proper amount of water into the diapers every few minutes, and wait for one minute after the water is absorbed by the diapers.

(3) Take a dry paper towel and press it on the absorbent side of the diaper. After pressing, observe the wetting degree of the paper towel to judge the reverse osmosis.
