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. ^ 14 cl, 6 dwg, 4 tbl, 8 ex |
