FIELD: manufacture of cellulose formed articles using amino oxide process.
SUBSTANCE: method involves forming cellulose solution in aqueous oxide of tertiary amine; settling cellulose from formed solution; washing and drying thus produced article; adding into cellulose solution and/or its basic component chitosone polymer, or treating formed article with chitosone polymer before drying procedure. Chitosone polymer contains chitosanic salt with inorganic and/or organic acid and is practically fully soluble in standard spinning solution. Also, solution of cellulose in oxide of tertiary amine and formed article are described in specification.
EFFECT: increased efficiency and improved quality of formed cellulose products.
