摘要： The present invention provides a novel nonwoven felt fabric, which is made of at least one low-melting-point short fiber and at least one high-melting-point short fiber of same type or different types, wherein the fabric is stiff enough to be self-sustaining and have the ability of shape maintenance. The felt fabric exhibits excellent pleatability, moldability and compressive strength. The invention also provides a method for producing the felt fabric, and a filter comprising the felt fabric used as the material of a filter medium of the filter, wherein the filter medium requires no support structure to stand alone and persistently retains its shape.

摘要： The invention provides a connector assembly for fastening filter elements onto a supporting plate of a press filter, comprising a first cylindrical core, a first flange extending outward from the first cylindrical core, a second cylindrical core, and a second flange extending outward from the second cylindrical core. The first cylindrical core is shaped and dimensioned such that it snugly passes through and is meshed with a central through hole of the supporting plate, and the second cylindrical core is shaped and dimensioned such that it snugly passes through and is meshed with the first cylindrical core. Both the first cylindrical core and the first flange and both the second cylindrical core and the second flange are respectively molded integrally from a non-woven fabric which has the ability of self-sustaining and shape maintenance, and is moldable. The invention also relates to a press filter fitted with the connector assembly.

摘要： The present invention provides a novel needle-punched nonwoven felt fabric which is made of same or substantially similar melting point short fibers of same type or different types, preferably made of one melting point short fibers of same type, wherein the felt fabric is stiff enough to be self-sustaining and has the ability of shape maintenance. The felt fabric exhibits excellent pleatability, moldability and compressive strength. The invention also provides a method for manufacturing the felt fabric, and a filter comprising the felt fabric used as the material of a filter element of the filter, wherein the filter element requires no support structure to stand alone and persistently retains its shape. The present invention further provides use of the felt fabric as a sound absorbing material.
