ABSTRACT

Absorbency has been always regarded as one of the most important features desired by consumers in disposable diapers. Absorption and retention capacity of a wood mixture pulp (fluff) and other fibers (acrylic and viscose), designed for production of the core of disposable diapers were studied. The kinetics of absorption as other main performance parameter of these products was also studied. The measurement of the performance parameters was carried out in the broad range of component weight ratios with a NaCl solution. The incorporation of these fibers was carried out also in the presence of super absorbent polymer particles. The behaviour of the components was found to improve absorption and retention capacity and also to cause a rise of absorbency rate. The insertion of acrylic fiber seems to limit the occurrence of the gel blocking phenomenon.
