Abstract
This report covers the accelerated aging in selected atmospheres of handsheets made from various chemical modifications of one wood pulp, and the interrelations of the changes in wet strength, acidity, and fiber strength. Handsheets were made from (1) untreated pulp, (2) pulp deashed with dilute hydrochloric acid, and (3) pulp subjected to ion exchange papermakers' alum (aluminum sulfate). Changes in acidity, fiber strength, and wet strength of the hand-sheets aged in various atmospheres are summarized. -- AATA
