シ、またおむつの嵩もかさむといった問題点があった。However, these conventional disposable diapers use a lot of cotton pulp, super absorbent polymer, etc. so that they can be used both during relatively short periods of use and during long periods of use at night. When used sparingly, a considerable portion of the absorbent material is discarded without absorbing water, which is not only wasteful in terms of cost and resources, but also creates a large amount of waste and increases the bulk of the diaper. There was a problem that it was bulky.
また、これらの無駄をはぶくために綿状バμプ、高吸水
性ポリマー量を減らすと夜間に使用した場合、漏れが生
ずるといった問題点があった。Furthermore, in order to eliminate these wastes, reducing the amount of cotton-like bap and super absorbent polymer resulted in problems such as leakage when used at night.
