Optimization of the Fibrous Component Absorption Performance of Hygienic Product Absorbent Core

摘要

Absorbency has been always regarded as one of the most important features desired by consumers indisposable 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 mainperformance parameter of these products was also studied. The measurement of the performance parameters was carriedout in the broad range of component weight ratios with a NaCl solution. The incorporation of these fibers was carried outalso in the presence of super absorbent polymer particles. The behaviour of the components was found to improveabsorption and retention capacity and also to cause a rise of absorbency rate. The insertion of acrylic fiber seems to limitthe occurrence of the gel blocking phenomenon.
