The present invention relates to a chemically modified kraft paper fiber comprising catalytically oxidized cellulose treated with carboxylation acid and having a carboxyl content greater than 6 meq/100g, an aldehyde content less than 1 meq/100g and a viscosity less than 5.5mPa·s . The pulp cellulose has an increased carboxyl content to achieve improved antimicrobial, anti-yellowing and absorption properties. |
