Description
Известен способ получени пр дильных р:а€ТБорОв из смбсей роизводиых целлюлозы с другими синтетическими полимерами.There is a known method of obtaining spinning: carbon dioxide from smelt produced cellulose with other synthetic polymers.
Дл повышени эластичности гидратцеллюлозного волокна предложено в качестве другого полимера использовать поливиниловый спирт, а в качестве растворител использовать смесь водного раствора этилендиамина и кадоксена (водный раствор кадмийэтилендиаминового комплекса).To increase the elasticity of the cellulose hydrate fiber, it was proposed to use polyvinyl alcohol as another polymer, and to use a mixture of an aqueous solution of ethylene diamine and cadoxene (an aqueous solution of the cadmium ethylene diamine complex) as a solvent.
Содержание поливинилового спирта по отношению к весу целлюлозы в пр дильных растворах может мен тьс от 1 до 40%. Целесообразно пр дильный раствор приготовл ть из смеси растворов целлюлозы в кадоксене и поливинилового спирта в водном растворе этилендиамина.The content of polyvinyl alcohol in relation to the weight of cellulose in the spinning solutions can vary from 1 to 40%. It is advisable to prepare the dope from a mixture of cellulose solutions in cadoxene and polyvinyl alcohol in an aqueous solution of ethylene diamine.
Волокна, полученные из таких пр дильных растворов по методу мокрого формовани с применением солевых и глицериновых осадительных ванн, имеют хорошие механические показатели.The fibers obtained from such spinning solutions by the wet forming method using salt and glycerol precipitation baths have good mechanical properties.
Пример 1. При перемешивании и температуре О-4°С приготавливают 5,8%-ный раствор целлюлозы в кадоксене, содержанием 6 вес. % кадми и 25 вес. % этилендиамина. Отдельно при 80°С готов т 16%-ный раствор поливинилового спирта в 25%-ном водном растворе этилендиамина. Дл приготовлени 1 кг пр дильного раствора при комнатной температуре смешивают 927,5 г раствора целлюЛозы и 72,5 г раствора поливинилового спирта.Example 1. With stirring and a temperature of about -4 ° C prepare a 5.8% solution of cellulose in cadoxene, containing 6 wt. % cadmium and 25 wt. % ethylenediamine. Separately, at 80 ° C, a 16% solution of polyvinyl alcohol in a 25% aqueous solution of ethylenediamine is prepared. To prepare 1 kg of the spinning solution, 927.5 g of cellulose solution and 72.5 g of polyvinyl alcohol solution are mixed at room temperature.
Соотношение целлюлозы и поливинилового спирта в полученном растворе составл ет 1:5.The ratio of cellulose and polyvinyl alcohol in the resulting solution is 1: 5.
Пример 2. К 72 г 15%-ного раствора поливинилового спирта в 26%-ном водном растворе этилендиамина, полученному так же, как и в примере 1, прибавл ют 878 г кадоксена , и в этом растворе при О-4°С раствор ют 50 г целлюлозы.Example 2. To 72 g of a 15% aqueous solution of polyvinyl alcohol in a 26% aqueous solution of ethylenediamine, prepared in the same manner as in Example 1, 878 g of cadoxene was added and dissolved in O-4 ° C in this solution 50 g of cellulose.
Волокна, полученные из пр дильных растворов , приготовленных по предлагаемому способу, имеют прочность 18-22 ркм и выдерживают 1000-4000 двойных изгибов при нагрузке 10% от разрывной.The fibers obtained from the spinning solutions prepared by the proposed method have a strength of 18–22 pkm and withstand 1000–4000 double bends with a load of 10% of the breaking strength.
