Application of SAP super absorbent polymer in diapers

Diapers have become one of the modern hygiene products. Due to the introduction of super absorbent polymer (SAP), diapers have achieved a qualitative leap in terms of water absorption, comfort and reliability.

Traditional diapers mainly use wood pulp as the water-absorbent material, which has poor water absorption and can easily lead to problems such as urine leakage and moisture discomfort. As an efficient water-absorbent material, SAP can absorb tens or even hundreds of times its own weight in liquid, stably locking the liquid inside the diaper while keeping the surface dry, providing longer dry protection.

How SAP works

SAP is a polymer with a cross-linked structure. There are a large number of cross-linking points within its molecules, forming a large number of pore structures. When SAP comes into contact with liquid, the liquid is quickly adsorbed into these pores, forming a gel-like substance that holds the liquid firmly within it and prevents spillage. This molecular-level water absorption mechanism makes SAP an ideal water-absorbent material.

Application of SAP in diapers

Improve water absorption performance: The introduction of SAP greatly improves the water absorption performance of diapers, which can quickly absorb urine and lock it stably inside the diaper, effectively preventing urine leakage.

Keep the diaper dry and comfortable: SAP can convert the absorbed urine into a gel-like substance, effectively preventing the reflux of urine, keeping the surface of the diaper dry, and providing the baby with continuous dryness and comfort.

Reduce the volume of diapers: Since SAP has extremely strong water absorption capacity, the amount of SAP required for the same water absorption is much less than that of traditional wood pulp materials. Therefore, the volume of diapers can be greatly reduced and the wearing comfort is improved.

Supports nighttime use: The high water absorption performance of SAP allows the diaper to support nighttime use, keeping the baby dry even if the baby sleeps for a long time.
