Introduction

David P. Duggan is a notable inventor based in Green Bay, WI (US), recognized for his contributions to the field of absorbent paper products. With a total of 4 patents to his name, Duggan has made significant advancements in the manufacturing processes of absorbent cellulosic materials.

Latest Patents

Duggan's latest patents include innovative processes for creating absorbent sheets through a fabric crepe process. This method involves compactively dewatering a nascent web, followed by wet belt creping at an intermediate consistency of 30 to 60 percent. The process is designed to redistribute the fiber on the belt, which is preferably made of fabric. The web is then adhesively applied to a Yankee dryer using a specialized creping adhesive, such as poly(vinyl alcohol)/polyamide, which facilitates high-speed transfer. The resulting absorbent sheets exhibit impressive properties, including an absorbency of at least 5 g/g, a CD stretch of at least 4 percent, and a maximum CD modulus at a CD strain of less than 1 percent.
