Application of Deep Grooved Polyester Fiber in Composite High Absorbent Paper, 1998 Nonwovens Conference Proceedings
High absorbent products such as diaper, incontinence and other health care products, derive their superior absorbency, in part, from the unique capillary of their structure. Deep grooved polyester fiber, used in combination with chemical cellulose, enables the paper designer to engineer high capillarity into the paper product. A primary objective of this study was to enhance the rate of liquid phase transport within the paper structure in a component known in the trade as the "surge layer" or "wicking layer". This study has shown significant advantages in liquid phase flow rates in structures designed as polyester/cellulose composites. A secondary element of study utilized an ultrasound instrument to quantify the liquid wetting rates.
