Mercerization process of pulp to produce high porous material

This invention relates to mercerized cellulose fibers which form a fibrous web that exhibit an Air Porosity equal to or greater than about 100 cfm/sq ft as determined by the procedure of TAPPI T251 cm-85 on 60 gsm handsheets at a pressure of 125 Pa, and preferably having a kink index equal to or gre...

Zusammenfassung:	This invention relates to mercerized cellulose fibers which form a fibrous web that exhibit an Air Porosity equal to or greater than about 100 cfm/sq ft as determined by the procedure of TAPPI T251 cm-85 on 60 gsm handsheets at a pressure of 125 Pa, and preferably having a kink index equal to or greater than about 2.5 and a curl index equal to or greater than about 0.28 as measured by Fibers Quality Analyzer (FQA) manufactured by Optest, Canada.
