Abstract
This invention relates to the process of manufacture of resin treated mercerized cellulose fibers and fibrous products prepared therefrom and is directed particularly to a method of improving permeability and bulking properties and reducing water retention value (WRV) of a conventional high permeability bulk pulp. The invention also includes the improved cellulose fibers, cellulosic sheet materials containing said fibers, and products therefrom (such as automotive oil and air filters).
