Disclosed is a PPS member having an excellent fastness to lights such as ultraviolet light, and of which color does not change even when the member is used outdoors, while retaining the characteristics of PPS. The polyphenylene sulfide member according to the present invention is characterized by having a light-fastness rating of Class 1 or higher, against light from an ultraviolet carbon arc lamp, which rating is measured in accordance with JIS L-0842.

Polyphenylene sulfide member and method for producing the same

The object of this invention is to provide a heat resistant fabric having high stiffness at high temperature and also high chemicals resistance. The heat resistant fabric of this invention is a fabric consisting of heat resistant fibers, characterized in that the contacts between the fibers constituting the fabric are bound by means of an inorganic binder. Furthermore, a preferable process for preparing the heat resistant fabric of this invention comprises the steps of impregnating a fabric consisting of heat resistant fibers with a sodium silicate aqueous solution, and drying in an atmosphere containing carbon dioxide, to bind the contacts between the fibers constituting the fabric by means of silicon oxide.
