The use of wood cellulose in the search for the development of a new generation of composites is increasing day by day. According to an article published on September 13, 2019, researchers created a new type of composite by blending wood cellulose fibers and spider web yarns with silk proteins. It is said that the silk used in researches is formed by artificial means.
