ABSORBENT MACROSTRUCTURE MADE FROM MIXTURES OF DIFFERENT HYDROGEL-FORMING ABSORBENT POLYMERS FOR IMPROVED FLUID HANDLING CAPABILITY

摘要

Porous, absorbent macrostructures (52) having improved fluid han dling capability that include inter-particle bonded aggregates, and are useful in absorbent articles (48) such as diapers, adult incontinence pads and sanitary napkins, are disclosed. The inter-particle bonded aggregates of these macrostructures (52) are made from mixtures of particulate absorbent polymers having different fluid handling properties, different shapes, or both. These macrostructures (52) can be made from a wider variety of hydrogel-f orming absorbent polymers without sacrificing desired fluid handling properties, and without being prone to gel blocking.
