Abstract

A filter material comprises an air- pervious shaped interstitial body formed of one or more multifolded continuous filaments of thermoplastic synthetic plastics material, the shape of said body being maintained by a joining of the said filament to itself or of said filaments to themselves and/or each other at intersections of adjacent lengths of said multifolded filament or filaments throughout the length of the said body. The aforesaid filter material may be produced by feeding one or more continuous filaments into a stuffer chamber, preferably constituted by a coiled tension spring 13, of the desired cross-section maintained at an elevated temperature-and continuously folding said filament or filaments within said chamber whereby to fill at least a portion of the length of said chamber, maintaining said folded filament or filaments within said chamber for a time and at a temperature which sets the filament or filaments in the folded state and effecting a bonding of said folded filament or filaments at the intersections of adjacent folded lengths thereof. <IMAGE>
