Abstract: A manufacturing method of an electret processed product, comprising the steps of allowing a section nozzle ( 22 ) to come into contact with a nonconductive fiber sheet (S) so as to cross in the lateral direction of the sheet while running the sheet, allowing the surface of the sheet on the opposite side of the contact portion to come into contact with or to immerse into a water surface, sucking water from the suction nozzle ( 22 ) so that the water can be passed through the sheet in the thickness direction of the sheet to penetrate the water into the nonconductive fiber sheet (S), and drying the nonconductive fiber sheet (S), whereby a high quality and high performance electret processed product can be manufactured at a low cost.

Abstract: Disclosed are diaphragm cloth for a water electrolyzer and a manufacturing method therefor. The diaphragm cloth adopts a woven fabric, non-woven cloth or a knitted fabric composed of polyphenylene sulfide fibers. The average pore size of the diaphragm cloth is smaller than 10 µm, and under the condition of a pressure at 3 KPa, the venting quality of the diaphragm cloth is 2 L/cm 2 /min or less. The diaphragm cloth for a water electrolyzer of the present invention has the features of high gas-tightness, good hydrophilicity and excellent ion permeability, also has low cost, safety, environmental protection and light weight; and the manufacturing method is rapid, and has the features of high efficiency, no pollution, simple operation and saving energy.
