The second water absorption test of diapers

The second water absorption experiment of diapers According to the report of Life Channel of Shandong Radio and Television Station, it is very important to choose a suitable diaper for your baby, and the quality of diapers is very different. Moms can buy a few more brands of diapers and give them personally. For children, see which one is best. Let me talk about the water absorption performance of diapers. Experiments have shown that No. 2 diapers with the lowest single-piece price have better dryness than No. 1 and No. 5 diapers with higher prices. This also shows that the water absorption of diapers is not necessarily proportional to the price. After pouring 100 ml of ink water solution, although the dryness of the surface of the 5 types of diapers is different, at least they are all absorbed, and the difference in water absorption is not particularly large. The experimenter conducted a second water absorption experiment on the diapers. After five minutes, the experimenter poured ink on the diapers again to observe their water absorption. Five minutes later, I poured the ink solution on the No. 1 diaper again, and found that it was already very difficult to absorb water. The reporter found that the No. 1 diaper had very weak secondary water absorption. After slowly pouring an aqueous ink solution into its center, the aqueous solution was not absorbed at all but flowed out along the diaper. Compared with the first water absorption experiment, the secondary water absorption of No. 2 diapers is also greatly weakened. In the same way, the experimenter poured 100 milliliters of ink solution into No. 3 diapers. Although the No. 3 diaper is not absorbed by the center, it flows to the sides and is absorbed by both sides. No. 12 flows directly to the outside. Compared with other diapers, No. 3 has better water absorption. After pouring the ink solution into No. 4 diapers, the solution was quickly absorbed. Almost nothing is left outside, it is basically adsorbed in the center of the surface, and the surface is still relatively dry. After 30 seconds, the experimenter used a piece of dry paper towel to test the surface dryness of No. 4 diapers after the second water absorption test. It is found that there is very little water on the paper towel. The secondary water absorption of No. 4 is almost the same as the primary water absorption of Nos. 1, 2, and 3, indicating that the water absorption is strong. The secondary water absorption of No. 5 diapers was also greatly reduced, and the ink water solution poured almost all flowed out along the sides of the diapers. Through this experiment, it can be seen that the secondary water absorption of No. 3 and No. 4 diapers is better than that of No. 1, No. 2 and No. 5. After standing for a period of time, the No. 2 diapers even showed back seepage. The water absorption of the diaper is very important, it is related to the baby's feeling and health.
