Changes in Dimensions of Web During Fluid Uptake and its Impact on Absorbency, 1994 Nonwovens Conference Proceedings

B.S. Gupta, C.J. Hong

A series of webs containing blends of hydrophilic and hydrophobic fibers were prepared using air laying techniques. These were needle punched to a number of levels. Absorbent characteristics were assessed on the GATS using several different environmental pressures and three different fluids. The absorbency device allowed simultaneous measurement of the changes in web thickness during the wicking process. The results showed that the absorbency phenomena can be effectively explained using modification of classical equations if changes in structure accompanying absorption were taken into consideration.
