A method of weaving fabric for use in the manufacture of a vehicle air-bag includes: providing a weaving reed having a plurality of adjacent cells; introducing regular warp yarns into at least some of the cells; introducing an additional warp yarn into one of the cells that already includes a regular warp yarn; and carrying out a weaving process. In the weaving process, weft yarns are interwoven with the regular warp yarns and the additional warp yarn. The regular warp yarns each remain within one cell throughout the weaving process. The additional warp yarn is moved from a first cell to a second cell during the weaving process.

In or relating to air-bags

A fabric for use in the manufacture of an inflatable air-bag, the fabric having interwoven warp fibers and weft fibers which are arranged substantially perpendicular to one another, one or more of the warp and weft fibers being at least partially coated with an adhesive substance to increase the friction between the warp and weft fibers at their intersections. In another embodiment, the fabric is formed from fibers having a central core and another sheath.

Fabric for use in the manufacture of an inflatable air-bag

A method of forming a fabric for an air-bag, the method comprising providing a plurality of yarns, each yarn being formed from a plurality of individual fibres; applying an activatable additive or coating to each yarn, the additive or coating initially not being activated and wherein, prior to activation, the additive or coating presents little or no impedance to the relative movement of the fibres within the yarn and, following activation, the additive or coating binds fibres within the yarn to one another to prevent or hinder relative movement of the fibres in the yarn with respect to one another; and passing the yarns through an activation zone including a compressing component which applies a compressive force to the yarns, the additive or coating being activated as the yarns pass through the activation zone so that the yarns each have a substantially flat configuration.
