Embodiment 1

[0027] The warp and weft yarns are all nylon 66 filaments with a total fineness of 800dtex, a number of 210, and a circular cross section. Warp the above-mentioned filaments, and then weave them into plain weave fabrics with a water jet loom; use silicone resin and coat them with a doctor blade method to obtain a warp density of 41 strands / inch and a weft density of 41 strands / inch , the coating amount is 35g / m 2 The invention discloses a reinforcing fabric for an airbag, and the reinforcing fabric is used in preparing the airbag. The relevant physical properties of the fabric were evaluated and are shown in Table 1.

Embodiment 2

[0029] The warp and weft yarns are made of nylon 66 filaments with a total fineness of 940dtex, 140 threads, and a circular cross section. Warp the above-mentioned filaments, and then weave them into plain weave fabrics with a water jet loom; use silicone resin and coat them with a doctor blade method to obtain a warp density of 38 threads / inch and a weft density of 38 threads / inch , the coating amount is 35g / m 2 The invention discloses a reinforcing fabric for an airbag, and the reinforcing fabric is used in preparing the airbag. The relevant physical properties of the fabric were evaluated and are shown in Table 1.

Embodiment 3

[0031] The warp and weft yarns are made of nylon 66 filaments with a total fineness of 700dtex, 108 threads, and a circular cross section. Warp the above-mentioned filaments, and then weave them into twill fabrics with a water-jet loom; use silicone resin and coat them with a doctor blade method to obtain a warp density of 42 threads / inch and a weft density of 42 threads / inch , the coating amount is 50g / m 2 The invention discloses a reinforcing fabric for an airbag, and the reinforcing fabric is used in preparing the airbag. The physical properties of the fabric were evaluated and are shown in Table 1.

Abstract

The invention discloses a reinforcing fabric for an airbag and an application thereof. The warp and weft yarns constituting the reinforcing fabric are polyamide filaments with a fineness between 650 and 1200 dtex, and the coating amount of one layer is 35 ~100g / m2 synthetic resin. The reinforcing fabric for the airbag prepared by the invention has the advantages of high heat resistance and high strength, and the reinforcing fabric is used in preparing the airbag bag.

Description

technical field [0001] The invention relates to a reinforcing fabric for an airbag and its application. Background technique [0002] In recent years, safety airbag has attracted more and more attention as one of automobile safety spare parts. When a car collides, the driver and passengers crash into the steering wheel and other interior parts at high speed and are injured. Installing safety belts, airbags and other protection systems on cars can restrain passengers on their seats during a crash, limit the movement distance of their heads and chests, and avoid violent collisions with interior components, thus playing a protective role. [0003] When the car is hit by a collision, the gunpowder of the gas generator explodes, the airbag deploys after only 0.003ms, and the airbag deflates after 0.2ms. Depending on the type of gas generator, the maximum temperature of the gunpowder explosion can reach 1800 °C. This requires the airbag cloth to have certain heat resistance and...
