What is SAP (Superabsorbent Polymer)?
SAP is a special type of polymer that can absorb and hold large amounts of liquid. It is often found as small beads or granules. When these beads touch liquid, they swell and turn into a gel. This gel helps SAP absorb and keep large amounts of liquid.
The most common raw material used in products like sanitary napkins, feminine pads, incontinence pads, and diapers is sodium polyacrylate. It is a water-soluble substance that can absorb up to 300 times its weight in water. This makes it perfect for products that need to absorb a lot of fluid.
How SAP is used in Sanitary Napkins Raw Materials?
In sanitary pads, SAP is often applied to a tissue or paper, which is then placed in the absorbent core of the pad. A typical sanitary napkin has four main raw material layers:
- Acquisition Layer: This layer is the top one and touches the skin. It is soft and helps keep the skin dry by allowing liquid to pass into the next layer. (Ace Nonwoven Pvt. Ltd. is the 1st and leading manufacturer of Hot Air Through Nonwoven Top sheet layer which is very soft in touch, gives the most comfort and dryness.)
- Distribution Layer: This layer spreads the liquid evenly to the next layer. It helps move the fluid quickly from the acquisition layer to the absorbent core. (Ace Nonwoven Pvt. Ltd. manufactures ADL – Acquisition Distribution Layer with the process of Hot Air Through Nonwoven and widely supplying to Napkin and Diapers brands worldwide.)
- Absorbent Core: This is the main layer where SAP is located. SAP is mixed with fluffed cellulose pulp to form a core that quickly absorbs and holds large amounts of fluid.
- Barrier Layer: This bottom layer is made from a leak-proof material like polyethylene (PE). It keeps the fluid from leaking out of the pad.
Benefits of Using SAP Sheet or SAP Paper as a raw material in Sanitary Napkins, Baby Diapers, and Incontinence Pads–
- Quick Absorption: SAP can absorb up to 300 times its weight in water, making it highly effective at quickly soaking up large amounts of fluid.
- Odor Control: SAP helps trap odor-causing bacteria in the gel, preventing bad smells.
- Leakage Control: The gel created by SAP locks in the fluid and helps prevent leaks.
- Comfort: SAP absorbs fluid fast, keeping the user dry and comfortable by preventing wetness.
- Long-Lasting: SAP holds more liquid than cellulose fibers, so it can keep fluid locked in for a longer time.
- Ultrathin: SAP Sheet replaces fluff in the Napkin and Diapers which is heavy and bulky. SAP Sheet provides ultrathin shape and can fit to the body gives more comfortable movements.
Overall, SAP is great for absorbing large amounts of fluid, controlling odors, and preventing leaks.
