Felt from superabsorbing polymer and method of manufacturing thereof

Предметом изобретения является войлочный материал, содержащий по меньшей мере один войлочный слой и один содержащий абсорбент слой, способ изготовления войлочного материала и применение войлочного материала в текстильных изделиях, обуви, в технических и медицинских целях. Войлочный материал согласно изобретению обладает преимуществами традиционных войлочных материалов в отношении тепло- и звукоизоляционных свойств и является воздухопроницаемым в сухом состоянии. Однако благодаря специальному выполнению этот материал в мокром состоянии не пропускает воду и, следовательно, пригоден для уплотнения многих видов материала. Войлочный материал согласно изобретению связывает в большей степени влагу воздуха или связывает воду иначе, чем традиционные войлочные материалы. Задачей настоящего изобретения является создание содержащего абсорбент материала с высокой механической прочностью и хорошей воздухопроницаемостью в сухом состоянии, кроме того, материал должен быть пригодным для кондиционирования воздуха, как, например, вентиляция, обезвоживание и/или увлажнение соответствующих выполненных с его помощью изделий. 4 н. и 29 з.п. ф-лы, 10 ил.
