Abstract (en)
[origin: WO2014195418A1] The invention relates to a method for producing polyacrylonitrile-based nonwoven fabrics. According to said method, the polyacrylonitrile spinning solution is forced through the holes of a nozzle strip and is stretched by a flow of air by a multiple before the filaments are regenerated by wetting them with a coagulation medium. The fiber curtain formed is placed on a conveyor belt, washed and dried. The invention also relates to nonwoven fabrics of the aforementioned type and to the use thereof.
