Abstract: A method of manufacturing a filter resistant to high temperatures and mechanical stress, includes forming a fiber secured to a suitable framework wherein a double-sided knitted fabric is knitted from a fiber resistant to high temperatures, e.g. poly(m-phenyleneisopthalamide) fiber, on a knitting machine with two rows of needles, and a reinforcing fiber resistant to high temperatures, e.g. aromatic polyamide fiber is fed on top of the fabric, and on top of this a new double-sided fabric, wherein the reinforcing fiber remains in the channels formed by the transverse loops of the knitted structure, after which a piece of this fiber structure is secured to a suitable frame.
