| titleOfInvention | Method of preparing celluloses for viscous fibers' production |
| abstract | The invention relates to a method for producing cellulose for the production of viscose fiber from lignocelluloses, such as deciduous wood, coniferous wood or annual plants, in which lignocellulose is first processed in a digester using saturated steam for prehydrolysis of hemicelluloses and then treated with hot black liquor without pressure reduction ( НСi) of the previous cooking to obtain sulfate cellulose, as well as, if necessary, with the addition of fresh white liquor (WL), to neutralize the The total reaction product, due to which a neutralization liquor (NL) is formed in the digester. After adding the amount of alkali necessary for delignification in the form of fresh white liquor (WL), if necessary, and in combination with the displacement of neutralization liquor (NL), and when setting the temperature, then cooking is carried out with or without a temperature gradient. When the desired degree of dissolution is achieved, cooking is completed by displacing hot black liquor (HL) with a cold alkaline wash filtrate (WF), at the same time the cellulose is freed from the existing lignin degradation products and the cellulose thus obtained is discharged from the digester at a temperature below 100 ° C. |
