Production Of Braille Paper From Recycled Fiber Treated With Cellulose Acetate And Optimization By Response Surface Methodology (Rsm)

Paper dust and oil palm empty fruit bunch (EFB) unbleached chemical pulps were derived to a low-grade cellulose acetate in this study. Papers made from secondary fiber were then treated with the resultant cellulose acetate (CA) to produce paper that is suitable to be used on Braille embosser but in...
