Abstract

Изобретение касается текстильного материала, содержащего по меньшей мере один слой полимерных нановолокон диаметром до 600 нанометров, изготовленных методом электростатического формования волокна из раствора полимера. Полимерные нановолокна содержат частицы низкомолекулярного вещества, растворённого или диспергированного в растворе полимера, из которого волокна формуются электростатическим методом, или содержат частицы низкомолекулярного вещества, образовавшегося в результате последующей химической реакции исходного низкомолекулярного вещества, растворённого или диспергированного в растворе, из которого волокна формуются электростатическим методом. Далее изобретение касается способа изготовления слоя нановолокон из полимерного раствора методом электростатического формования волокна в электрическом поле, созданном за счёт разности потенциалов между заряженным и противоположным электродами, в котором раствор полимера подводится в электрическое поле для формования волокна поверхностью вращающегося заряженного электрода, при этом образующиеся в этом электрическом поле нановолокна увлекаются к противоположному электроду и укладываются на предназначенную для этого поверхность. Раствор полимера для формования волокна содержит частицы низкомолекулярного вещества, которые при формовании волокна вовлекаются вместе с полимером в образующиеся волокна.The invention relates to a textile material containing at least one layer of polymer nanofibers with a diameter of up to 600 nanometers, made by the method of electrostatic spinning of a fiber from a polymer solution. Polymeric nanofibers contain particles of a low molecular weight substance dissolved or dispersed in a polymer solution from which fibers are formed by the electrostatic method, or contain particles of a low molecular weight substance formed as a result of the subsequent chemical reaction of the original low molecular weight substance dissolved or dispersed in a solution from which the fibers are formed by an electrostatic method. Further, the invention concerns a method of manufacturing a layer of nanofibers from a polymer solution by electrostatic spinning a fiber in an electric field created by the potential difference between charged and opposite electrodes, in which the polymer solution is fed into an electric field to form a fiber with a rotating charged electrode surface, The electric field of the nanofibres is carried away to the opposite electrode and placed on the intended surface. The polymer solution for forming the fiber contains particles of low molecular weight substance, which, when forming the fiber, are involved together with the polymer in the formed fibers.
