Description
В известных способах получени вискозы в одном анпарате при мерсеризации наблюдаетс большое набухание целлюлозы, благодар чему дл полного и равномерного пропитывани целлюлозы расчетного количества щело.чи не хватает.In the known methods of obtaining viscose in one antaratic, during mercerization a large swelling of cellulose is observed, due to which a calculated amount of lye is not enough for complete and uniform impregnation of cellulose.
Предлагаемый способ получени вискозы в одном аппарате дает возможность уменьшить набухание целлюлозы при мерсеризации и получать однородный продукт при низком содержании шелочи. Это достигаетс тем, что целлюлозу обрабатывают раствором гор чей ш.елочи , после чего ксантогенирование провод т известными способами.The proposed method for producing viscose in one apparatus makes it possible to reduce the swelling of cellulose during mercerization and to obtain a homogeneous product with a low content of silk. This is achieved by treating the cellulose with a solution of hot shaluloch, after which the xanthogenation is carried out by known methods.
Дл осуществлени способа целлюлозу с самого начала процесса мерсеризации обрабатывают расчетным количеством гор чего едкого натра (нри температуре около 60°) с тщательным перемещиванием.To carry out the process, from the very beginning of the mercerization process, the pulp is treated with a calculated amount of hot caustic soda (at a temperature of about 60 °) with careful movement.
После мерсеризации щелочную целлюлозу охлаждают до температуры 10° и ниже и иодвергают ксантогенированию известным путем.After mercerization, the alkaline cellulose is cooled to a temperature of 10 ° and below and is subjected to xanthogenesis in a known manner.
Применение способа позвол ет в пр дильном растворе получать вискозу с содержанием целлюлозы более 8% и низким содержанием щелочи.The application of the method allows to obtain a viscose with a pulp content of more than 8% and a low alkali content in the spinning solution.
Предмет изобретени Subject invention
Способ иолучени вискозы в одном аппарате путем обработки целлюлозы раствором щелочи с последующим ксантогенированием, отличающийс тем, что, с целью получени более однородного продукта, целлюлозу обрабатывают раствором гор чей щелочи.A method of viscose production in a single apparatus by treating cellulose with an alkali solution followed by xanthogenesis, characterized in that, in order to obtain a more homogeneous product, the cellulose is treated with a solution of hot alkali.
