absorbent core material

In the current context of continuous changes in the global population structure, the issue of aging population is becoming increasingly prominent. According to relevant data, it is predicted that the proportion of elderly people aged 65 and above will significantly increase in the next few decades. This trend not only brings a series of social and economic challenges, but also creates vast development space for the adult diaper market. As a key product to solve incontinence problems, adult diapers have attracted much attention for their quality and performance. One of the core factors determining the quality and performance of adult diapers is the selection and application of raw materials. Thoroughly analyzing the raw materials of adult diapers is of great significance for meeting the growing market demand, improving product quality, and promoting industry development. The core raw material of adult diapers: The absorbent core is the core part of adult diapers, and its performance directly affects the product's absorption capacity and water retention performance. At present, the mainstream absorbent core materials in the market mainly include wood pulp and polymer absorbent resin (SAP). ​ Wood pulp raw materials: As a traditional absorbent material, wood pulp has good water absorption and certain water retention capacity. It can quickly absorb urine and store it through the gaps between fibers. In some adult diaper products, the use of wood pulp can provide basic absorption function and is relatively affordable. However, wood pulp also has some limitations, such as relatively slow absorption rate, limited absorption capacity, and the tendency to clump and break after absorbing a large amount of urine, which affects the user experience of the product. ​   Polymer Absorbent Resin : Polymer water absorbent resin is a new type of functional material with super strong water absorption and retention properties. It can absorb hundreds or even thousands of times its own weight of water and firmly lock it in, making it less prone to backflow. In adult diapers, the addition of SAP can significantly increase the absorption capacity and speed of the absorbent core, enabling the product to quickly absorb and lock in a large amount of urine, keeping the surface dry. With the continuous advancement of technology, the performance of SAP is also constantly improving. For example, the emergence of some ultra-thin SAPs not only improves absorption performance, but also reduces pressure on the user's skin and enhances comfort. At present, the share of SAP in the absorbent core of adult diapers is increasing, generally accounting for about 30% -40%, and even up to 70% in some high-end products. ​ The development trend of adult diaper absorbent core materials: In order to further improve the performance of absorbent cores and meet consumers' demand for high-quality products, absorbent core materials are developing towards diversification and high performance. On the one hand, some companies have begun to develop and apply new composite absorbent materials, optimizing the combination of wood pulp and SAP, or adding other functional ingredients such as antibacterial agents and deodorizers to improve the overall performance of their products. On the other hand, with the increasing awareness of environmental protection, biodegradable absorbent core materials have also become a hot research topic. For example, the wood pulp based environmentally friendly and highly absorbent material developed by a domestic research team can decompose within two years, reducing its impact on the environment.
