If the diaper has an absorbency of at least 24 ml/g after one hour, the quality is considered acceptable. Other quality control factors besides absorbency are related to the diaper's fit and comfort. Particular attention must be paid to the melt characteristics of the nonwoven fabrics used to form the diaper's shell.

Disposable Diaper - an overview | ScienceDirect Topics

Masuda (1993) states that diaper dryness is correlated to absorbency under load (AUL, r = 0.81) and diaper leakage is inversely correlated to gel stability (r = 0.93). The trend has been to use lower amounts of fluff fiber and higher levels of SAP in hygiene products; these products may be as much as 30% SAP.

What is SAP – superabsorbent polymers

SAP or Superabsorbent polymers is a material which can absorb up to 300 times their weight in aqueous fluids. Once absorbed, they do not subsequently release it. They are therefore an ideal material for use in products which are designed to contain fluids such as baby diapers/nappies, incontinence products, and feminine hygiene pads and liners.
