The core layer revolution of baby diapers
The first change in the core layer of diapers is thinner, lighter and narrower. Absorbent core layer is an important factor to measure the quality of a diaper. Over the past time, the general trend in the development of diaper cores has been to make products narrower, thinner and lighter. Whether it is a foreign brand or a domestic brand, the new products launched are all based on ultra-thin, ultra-thin, and ultra-thin as the starting point for publicity.
The second change of the core layer is the change of material. The absorbent core layer of diapers in the domestic market is mainly a layered structure composed of pure wood pulp (fluff pulp) and super absorbent resin (SAP). In the future, the core material of diapers will change in a diversified direction, adding more fiber materials. For example, Zhuneng baby diapers use bamboo charcoal as chips to achieve functions such as eliminating odors and automatically adjusting humidity.
Another core revolution that addresses urine leakage is the 3D core geometry. Compared with ordinary diapers with a flat core layer, the 3D core geometry can reduce the chance of side leakage of urine.
