Description
Известны способы получени синтетических и искусственных волокон с ирименением в осадительных ваинах жирных кислот.Methods are known for the production of synthetic and artificial fibers with fatty acid irization in precipitating wines.
Описываемый сиособ получени вилокна «Нитрон ио сравнению с известными позвол ет иовысить физико-механические свойства синтетического волокна, что достигаетс применением в качестве осадительной ванны стеариновой кислоты.The described method of obtaining forks "Nitron and comparing with the known ones allows to improve the physicomechanical properties of synthetic fiber, which is achieved by using stearic acid as a precipitation bath.
Пример. 15-15,5%-ный ир дильный раствор полиакрилонитрила в дпметилформамиде . ириготовлениый из ирбдукта с удельной в зкостью 1,500-1,600 ио вискозиметру Оствальда и имеющий по шарику в зкость 300-400 сек.., продавливают черел (1и1льеру с отверсти ми диамстрсм 0,08-0.12 ММ в стеариновую |К().атул дионнуш ванну с т-емпературоЛ 70-.Example. 15-15.5% hydrochloride solution of polyacrylonitrile in dpmethylformamide. Irrigated irbduct with a specific viscosity of 1,500-1,600 and an Ostwald viscometer and having a ball viscosity of 300-400 seconds. with t-temperature 70-.
Подачу растворов устанавливают из расчета иолучени элементарного волокна с номером 4000-5000 после его выт жки.The supply of the solutions is established on the basis of the calculation of the yield of the elementary fiber with the number 4000-5000 after its stretching.

После выхода из коагулшишнной ванны нить подвергают выт жке при 160- 170° в ваннах, содерл;ащих соответствующие жидкости, например, глицерин. Ве .тичина выт жки 2000-3000%.After leaving the coagulation bath, the thread is subjected to stretching at 160-170 ° in baths containing suitable liquids, for example, glycerin. The amount of stretching is 2000-3000%.
После выт жки волокно поступает на бобины.After drawing, the fiber enters the reels.
Спр денное волокно подвергают промывке , сушке и последующпм операци м окоичательно отделки.The spun fiber is subjected to washing, drying and subsequent operations around sharpening.

Сносоо иол чени синтетического волокна с применением осадительных ванн, содержащих жирные кислоты, о т л п ч аю щ и и с тем, что, с целью повышени физико-механических свойств волокна на осиове полиакрилоиитрила в диметилформампде , в качестве осадительной ванны примен ют стеариновую кислоту.Removing synthetic fibers with the use of precipitation baths containing fatty acids, so on, and in order to improve the physicomechanical properties of the fiber on the axis of polyacryloyitrile in dimethylformamph, stearic acid is used as a precipitation bath .
