  • Electrospinning solution, polyvinyl alcohol nanofibers and ion-exchange membrane
    Patent number: 9364824
    Abstract: An ion-exchange membrane is provided, and the fibers of the ion-exchange membrane are obtained by electrospinning. The electrospinning solution contains 100 parts by weight of polyvinyl alcohol (PVA), 10-100 parts by weight of a modifier, 10-100 parts by weight of an ion exchanger, and 100-2,500 parts by weight of water. The modifier has a reactive group that can react with the hydroxyl groups of the PVA. The ion exchanger has a polar functional group that can form hydrogen bonds with the hydroxyl groups of the PVA, and has an anion group that can provide ion-exchange ability.

  • Method and Apparatus for Fabricating Functional Staple Fiber
    Publication number: 20140082889
    Abstract: A method for fabricating functional staple fiber is disclosed. A non-woven fabric substrate is provided. A metal layer or a metal oxide layer is sputtered on the surface of the non-woven fabric to obtain a complex fabric. The complex fabric is carded and becomes a plurality of functional staple fibers. An apparatus for fabricating functional staple fiber is also disclosed.
