Diapers generally consist of three main parts: surface covering layer, absorbent core layer and base fabric. The surface coating layer is close to the body, which can promote the rapid penetration of urine and effectively prevent back seepage, keeping the surface of the diaper dry. Whether the diaper is breathable is a question that people pay more attention to. So if there is no instrument, how to test whether the diaper is breathable? The author will introduce to you below. 1. Prepare two empty cups and two clean and dry plates, and two or more adult diapers that you want to compare. Of course, if you need more than one, prepare a few more cups and plates. 2. Unfold the two kinds of diapers, pour the prepared boiling water into one of the cups, cover the mouth of the cup with diapers, and cover the plate on the diapers. After doing it, follow the steps to test another pair of diapers. 3. After the two plates are covered, start timing. About 30 seconds to 1 minute. Okay, you can check the reaction on the plates. Steam passing through the diaper will condense small water droplets on the plate, which proves to be breathable. The proof that the dish is still dry is airtight. Generally, the air permeability of PE plastic bottom film is not very good. The air permeability of diapers is very important for comfort and skin health. If the air permeability is not good for the growth of bacteria, long-term wear will be more likely to form diaper rash and bedsores, which will greatly increase the difficulty of nursing. The above is about the method to test whether the diaper is breathable, I hope it can help everyone. Author:
