Abstract

In an attempt to take advantage of agricultural waste such as rice straw, which causes an environmental problem, it was used as a cellulose source by treatment with ionic liquid, which can be recovered after the reaction , into cellulose derivatives such as methyl cellulose, carboxymethyl cellulose and hydrogel preparation of these derivatives. Derivatives and hydrogels were used as additives to the pulp during the paper preparation process with other additives. The experiments showed an improvement in the mechanical and optical properties of the resulting paper. The study showed that the water absorption rate in the paper was increased with the addition of both MC and CMC to reach 230 and 290%, respectively. On the other hand , addition of both MC and CMC-hydrogels produced absorbed paper with water uptake till 773 and 600%, respectively.
