Impact of Carboxymethyl Cellulose-Bentonite Combination on Paper Performance

Aim of study: The purpose of this research is to evaluate the effects of applying CMC-BEN (carboxymethyl cellulose-bentonite) mixes to the surface of paper, both in terms of their impacts on paper qualities and the mixing ratios at which they were formed.Material and method: The production of CMC-BEN mixes was prepared by combining the components at the following rates: 1/1, 1/0.5, 1/0.25 and 1/0.1. Simple coating technique was utilized in order to apply the mixes to the surfaces of the paper. Strength performances of the papers, as well as their antibacterial activities, FTIR patterns, COBB values, and SEM views were evaluated. Main results: The solution absorption diminished with the addition of BEN to the CMC structure. The wet strength properties decreased in 100% CMC and CMC-BEN coated papers, and the dry strength and COBB values increased.Research highlights: On the surface of the paper, mixtures based on CMC and CMC-BEN were applied, each of which was made using a different mixing ratio. It was found that the CMC-BEN mixture had a positive impact on the paper's dry strength, but it had a negative impact on wet strength properties.
