Description
Известные способы получени вискозы не позвол ют повысить ее в зкость.Known methods for producing viscose do not allow to increase its viscosity.
В описываемом способе получени вискозы повышение ее в зкости достигнуто тем, что в мерсеризационный щелок ввод т тиоорганическое соединение, напрж1ер тиодигликоль, после чего полученнув алкалицеллюлозу перерайатывают по известной технологииIn the described method of obtaining viscose, its viscosity increase is achieved by introducing a thio-organic compound into the mercerization liquor, such as thiodiglycol, after which the alkaline cellulose is re-processed according to the known technology
При производстве вискозных волокон и пленок важной задачей вл етс наиболее выгодное распределение сероуглерода.с преимущественным использованием его на главнув реакцию :(образование ксантогената) и в возможно меньшей мере на побочные продукты (тритиокарбоната и пр.).In the production of viscose fibers and films, the most important task is the most favorable distribution of carbon disulfide. It is mainly used for the main reaction: (formation of xanthate) and, to the least extent possible, by-products (tritiocarbonate, etc.).
Введение в мерсеризационный щелок тиоорганических соединений улучшает развертыва П1е кш очвокой реакции взаимодействи Сероуглерода с компонентшли алкалицеллюлозы, а также улучшает физико-химические свойства систелш.The introduction of thioorganic compounds into the mercerization liquor improves the development of the P1e ksh ochkoi reaction of the interaction of carbon disulfide with alkalicellulose components, and also improves the physicochemical properties of the system.
Пршлер. В мерсеризационную щелочь задаетс тиооргаиическое соединение , напрш ер тиодигликоль, в количестве 1%, Далее следуют обычные операции.Prshler. In the mercerization alkali, the thioorganic compound is given, napr er thioglycol, in an amount of 1%. Then the usual operations follow.
Вискоза, полученна с добавкой тиодигликол , отличаетс повышенной в зкостью, меньшим полимером и той же зрелостью, что и виокоза без добавки.The viscose obtained with the addition of thiodiglycol is distinguished by an increased viscosity, a lower polymer and the same maturity as viocosis without an additive.
В зкость при этом значительно повншаето . ПРЦЩЕР ИЗОБРЩШИЯThe viscosity is significantly higher. PROMISTER IMAGES
Способ получени вискозы, отличающийс тем, что, с целью повышени ее в зкости, в мбрсеризационный щелок ввод т тиоорганическов ооединение, например тиодигликоль, после него полученную алкалицеллюлозу перерас5атывают по известной технологии.A method of producing viscose, characterized in that, in order to increase its viscosity, a thioorganic compound, for example thiodiglycol, is added to the mrbserization liquor, after which the alkalicellulose obtained is recalculated according to known technology.
