ARTICLE ANNOTATION

quote
Wood remains the main source of raw materials for the ever-growing production of pulp and fiber semi-finished products. Partial replacement with annual alternative plant raw materials is the most realistic opportunity to preserve forest resources and the ecology of the natural environment. In this article, studies were conducted on the extraction of cellulose from soybean stalks, followed by the casting of paper in various proportions. Rational conditions have been created for the method of obtaining cellulose from soybean stalks. The maximum yield of high-quality cellulose product has been increased to 45-48% (in terms of raw materials). In laboratory conditions, paper samples No. 1, obtained from 100% cotton and soy cellulose, and paper samples No. 2, bleached, with the addition of fillers and gluing agents, have a grinding degree of 40 0CR. The physico-mechanical properties of the obtained papers have shown that soybean fibers have high mechanical strength due to their long, straight and high degree of fibrillation. The breaking length ranges from 4818 to 4592 m in samples No. 1, and from 3742 to 3232 m in samples No. 2, which is 20% higher than the standard values. In addition, soy stems are a very dense material, the density and porosity of which are at the same level as some types of wood.
