Abstract
The process of dehydration, drying and rewetting of bagasse fiber during reuse will result in inevitable hornification. By controlling the dehydration mode and rate of the paper forming, the expansion and contraction rate of the fiber can be adjusted, thereby reducing the degree of hornification. When the liquid–solid ratio was 1.22, the rate of moisture removal in the early drying stage was the lowest at 0.986 g/s m2, and free water was mainly removed in this stage. The highest values of tensile index and tear index were 60.07 N m/g and 10.28 mN m2/g, respectively, and the lowest degree of fiber hornification was 22.51% at 5 cycles, which was 1.7% lower than that at a liquid–solid ratio of 1.00, indicating that the reduction of the drying rate of the capillary water can alleviate the generation of hornification, which provides a new way to solve the problem of fiber hornification.
期刊介绍：
Cellulose is an international journal devoted to the dissemination of research and scientific and technological progress in the field of cellulose and related naturally occurring polymers. The journal is concerned with the pure and applied science of cellulose and related materials, and also with the development of relevant new technologies. This includes the chemistry, biochemistry, physics and materials science of cellulose and its sources, including wood and other biomass resources, and their derivatives. Coverage extends to the conversion of these polymers and resources into manufactured goods, such as pulp, paper, textiles, and manufactured as well natural fibers, and to the chemistry of materials used in their processing. Cellulose publishes review articles, research papers, and technical notes.
