  • Description: This is an interim report describing in detail two mill runs and the associated laboratory work on the effects of replacing esparto with woodpulp fiber in the Navy H-60 filter paper. It is shown that an extremely good paper can be manufactured using causticized wood-pulp in place of esparto fiber. However, the paper relaxes considerably after manufacture to give a product similar in performance to the H-60 paper. It is shown that the 'flexing' effect can be eliminated partially by spray treatment of the wet paper with wetting agents with considerable loss in paper strength. The relaxation flexing, and 'break' effects all require further study. (Author)
