An improved inside-to-outside flow filter tube and method of manufacturing the tube, which filter tube comprises: a plurality of nonwoven fibers having interstices therebetween to define the porosity of the filter tube, the tube containing a binding agent at the junction of the fiber crossovers to provide a self-supporting structure of a defined wall thickness and filter porosity; and an open scrim reinforcing sheet material within the wall of the filter tube extending generally the length of the tube and at least one overlapping revolution about the tube diameter, the fibers of the filter tube bonded integrally through the open scrim material, thereby permitting the use of the filter tube in applications requiring inside-to-outside fluid flow without the necessity for an external peripheral support. |
