Title:
PRODUCTION OF EXTRA FINE FIBER COMPOSITE SHEET
Document Type and Number:
Japanese Patent JPH05310958
Kind Code:
A
Abstract:
PURPOSE:To provide the method for producing the extra fine fiber composite sheet excellent in the mechanical strength, heat resistance, flame retardancy and chemical resistance and having good flexibility and high water absorbency. CONSTITUTION:The method for producing the extra fine fiber composite sheet by spinning at least two kinds of fiber-forming polymers into conjugate fibers, producing a sheet-like product from the obtained conjugate fibers, applying a binder to the sheet-like product, and subsequently removing at least one of the polymers composing the conjugate fibers to leave the other polymer as the extra fine fibers is characterized by using at least one kind of polymer selected from a group of aromatic polymers containing thioether bonds in their main chain and aromatic polymers containing ether bonds as their main chain as the polymer composing the extra fine fibers and also using the emulsion of chlorosulfonated polyethylene and/or chlorinated polyethylene as the binder.
