Document Type and Number:
Japanese Patent JP6848982
Kind Code:
B2
Abstract:
A polyphenylene sulfide woven fabric for water electrolyser and manufacturing method thereof. The surface of the fiber constituting the polyphenylene sulfide woven fabric contains a hydrophilic group and the oxygen content of the surface of the fiber is 15% by weight or more. The hydrophilic group comprises a carbon-oxygen group and a sulfur-oxygen group, the carbon-oxygen group being at least one of a carboxyl group, a carbonyl group and an aldehyde group. The content of the carbon-oxygen group is 62 to 72% of the total number of the groups in the surface of the fiber, and the content of the sulfur-oxygen group is 6 to 15% of the total number of the groups in the surface of the fiber. The polyphenylene sulfide woven fabric for water electrolysers has good hydrophilicity, high air tightness characteristics, also has characteristics of simple process, energy saving, and low environmental pollution.
