    摘要: Uncoated technical fabric is produced in a dense weave with low air permeability. The fabric contains polyamide filament yarns with a hot air shrinkage of 6 to 15% (determined at 160.degree. C.) and has an at least substantially symmetrical fabric construction. The fabric is adjusted to the required air permeability by a treatment in an aqueous bath at 60.degree. to 140.degree. C.

    摘要: An air bag fabric has zones of differing air permeability which are variable in shape and size. A dobby, tappet or Jacquard machine may be used to weave, into a fabric having tight basic weave, window-like zones with a weave which differs from the basic weave, as a result of which these zones have a high air permeability. The zones of low air permeability are arranged in such a way that later they form the edges of cuts and seams. It is further possible to manufacture fabrics which have zones of differing air permeability by alternating sections of high warp or weft sett with sections of low warp or weft sett. The fabrics of the invention are suitable in particular for the filter part of air bags.
