Abstract: A self-lubricating fabric contains warp yarns or weft yarns that are composite yarns formed from fluorinated resin yarns and other yarns. The surface area of the other yarns on one surface of the fabric takes up 0 to 30% of the total surface area of the composite yarns, and the ratio of the section diameter of the other yarns to the section diameter of the fluorinated resin yarns in the composite yarns is 0.12 to 0.80. A method for producing the self-lubricating fabric and use of the self-lubricating fabric are also disclosed.

Abstract: The present invention discloses a self-lubricating fabric, a method for producing the self-lubricating fabric, and use of the self-lubricating fabric. Warp yarns or weft yarns of the fabric are composite yarns formed from fluorinated resin yarns and other yarns. The surface area of the other yarns on one surface of the fabric takes up 0 to 30% of the total surface area of the composite yarns, and the ratio of the section diameter of the other yarns to the section diameter of the fluorinated resin yarns in the composite yarns is 0.12 to 0.80. The self-lubricating fabric is characterized by low friction coefficient, excellent wear resistance property and high laminating strength, as well as simple production process, low cost and zero pollution to the environment. The fabric with low friction coefficient can be applied to mechanical moving parts, and is especially suitable for use in environment of low speed, high load and high or low temperature.

Abstract: A diaphragm cloth for a water electrolyzer includes a woven fabric, non-woven cloth or knitted fabric composed of alkali-resistant fiber at a common use temperature of no less than 150° C., an average pore size of the diaphragm cloth is less than 10 ?m and, under conditions of pressure of 3 KPa, venting quality of the diaphragm cloth is 2 L/cm2/min or less.

Abstract: Disclosed herein is a network-based voice over power lines (VoPL) telephone communication system, comprising a power line network, multiple clients and a server. The clients are respectively connected to the power line network for providing access for a user telephone and/or for providing a user operation interface. The server comprises at least one power interface and one telephone interface connected to the power line network, and to the clients via the power line network, for handling calls and transfer from the clients. The clients comprise power line adapters and/or power line telephones, the power line adapter comprises at least one power interface and one telephone interface for inputting numbers and/or information via keypads to make a call, and the power line telephone comprises at least one power interface for inputting numbers and/or information via keypads to make a call.
