Abstract
(EN)
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

Изобретение относится к способу производства целлюлозных формованных изделий аминооксидным способом, включающим формование раствора целлюлозы в водной окиси третичного амина, осаждение целлюлозы из сформованного раствора, а также промывку и сушку полученного таким образом формованного изделия. В раствор целлюлозы и/или его исходный компонент добавляют полимер хитозония, и/или формованное изделие перед сушкой обрабатывают полимером хитозония, причем полимер хитозония состоит из хитозановой соли с неорганической и/или органической кислотой и практически полностью растворим в стандартном прядильном растворе. Также изобретение касается раствора целлюлозы в окиси третичного амина и формованного изделия. 3 н. и 11 з.п. ф-лы., 11 табл., 6 ил.
