Method for producing a knitted fabric, especially for the production of a seat cover, characterised in that it comprises knitting first textile threads formed of a mixture of a polymer and an intumescent material and second textile threads of aramid, especially of polyaramid, by means of a double bed knitting machine comprising a front bed which carries a row of front needles and a rear bed which carries a row of rear needles, in accordance with a knitting pattern which comprises at least one sub-pattern (S1, S2, S3) defined in terms of width by at least six (A, B, C, D, E, F) pairs of front and rear needles and in terms of length by at least ten passes (P101 to P110, P201 to P210, P301 to P310) of threads through said six pairs of front and rear needles, each sub-pattern (S1, S2, S3) being such that: - the first two passes of thread (P101, P102, P201, P202, P301, P302) are passes of first textile threads, such that: • the first pass (P101, P201, P301) forms stitches such that a stitch is associated with one needle out of two adjacent front needles, • the second pass (P102, P202, P302) forms stitches such that a stitch is associated with each front needle that is not associated with a stitch on the first pass (P101, P201, P301), - the third to tenth passes of thread (P103 to P110, P203 to P210, P303 to P310) are passes of second textile threads, among which: • at least three of the third to tenth passes form stitches associated with two rear needles, • not more than one pass out of two successive passes forms stitches, • each pass forming stitches is preceded by one or two passes each forming at least one tuck associated with a rear needle, • at least one of the passes forming a tuck associated with a rear needle also forms a tuck associated with a front needle, • each of the rear needles is associated with a stitch during only one of the third to tenth passes and is associated with a tuck during only a different one of the third to tenth passes. - the first two passes of thread (P101, P102, P201, P202, P301, P302) are passes of first textile threads, such that: • the first pass (P101, P201, P301) forms stitches such that a stitch is associated with one needle out of two adjacent front needles, • the second pass (P102, P202, P302) forms stitches such that a stitch is associated with each front needle that is not associated with a stitch on the first pass (P101, P201, P301), • the first pass (P101, P201, P301) forms stitches such that a stitch is associated with one needle out of two adjacent front needles, • the second pass (P102, P202, P302) forms stitches such that a stitch is associated with each front needle that is not associated with a stitch on the first pass (P101, P201, P301), - the third to tenth passes of thread (P103 to P110, P203 to P210, P303 to P310) are passes of second textile threads, among which: • at least three of the third to tenth passes form stitches associated with two rear needles, • not more than one pass out of two successive passes forms stitches, • each pass forming stitches is preceded by one or two passes each forming at least one tuck associated with a rear needle, • at least one of the passes forming a tuck associated with a rear needle also forms a tuck associated with a front needle, • each of the rear needles is associated with a stitch during only one of the third to tenth passes and is associated with a tuck during only a different one of the third to tenth passes. • at least three of the third to tenth passes form stitches associated with two rear needles, • not more than one pass out of two successive passes forms stitches, • each pass forming stitches is preceded by one or two passes each forming at least one tuck associated with a rear needle, • at least one of the passes forming a tuck associated with a rear needle also forms a tuck associated with a front needle, • each of the rear needles is associated with a stitch during only one of the third to tenth passes and is associated with a tuck during only a different one of the third to tenth passes.
