SAP is a new type of functional polymer material, can absorb a hundred times or even thousands of times heavier than its own water, when it absorbs water and expands and solidifies with water, becoming a hydrogel, the ability to lock water is super strong, so the water can not flow out, even if squeezed hard will not leak. It is widely used in nursing pads. In the field of superabsorbent resin (SAP), according to the research, the three global SAP giants are Japanese Catalyst, German BASF and German Evonik.

Our Super Absorbent Polymer (SAP) plays an important role in keeping the skin dry by drawing moisture away from the skin and storing it in the core of the product. This not only improves user comfort, but also helps prevent skin irritation due to prolonged exposure to moisture, especially for diaper users. In addition, the control of fluids by the super-absorbent core helps to minimise leakage and prevent the spread of infection, ultimately improving the quality of life and personal dignity of people with bladder or bowel control problems.

Nursing pads raw material SAP supplier from China - LONSUN
This article delves into the crucial role of the Acquisition Distribution Layer (ADL) in disposable hygiene products. Positioned between the topsheet and the absorbent core, ADL swiftly absorbs and disperses liquids to maintain a dry and comfortable surface. It covers common materials (e.g., nonwoven fabrics, synthetic fibers), multi-layer structure designs, functional principles (including rapid diversion and liquid distribution), and performance evaluation methods (such as absorption rate, diversion volume, and reverse permeability). The piece also highlights environmental considerations, like biodegradable materials and recycling solutions. Additionally, it discusses ADL applications in specific products like diapers and sanitary napkins and looks ahead to future technological advancements, asserting that ongoing improvements in ADL technology will enhance the disposable hygiene products industry, better meeting consumer demands for hygiene, health, and environmental protection.
The main raw materials used in sanitary pads include a top layer (non-woven fabric or perforated film for skin contact and quick liquid absorption), an absorbent core (fluff pulp and superabsorbent polymer (SAP) to retain menstrual fluid), a back layer (PE or breathable film to prevent leakage), an adhesive (to secure the pad to underwear), and release paper (to protect the adhesive). Some products may also contain fragrances, antibacterial agents, or use organic cotton and other natural materials to meet different needs.
