Problems solved by technology

In the conventional example (4), due to the implementation of chemical treatment, the production cost has increased, and the chemical reagents will cause a decrease in the strength of the original yarn, that is, the decrease in the strength of the base fabric. If it is used as an air bag, there are problems in its reliability.
In the case of conventional example (5), there is a problem that the production cost increases because two types of yarns of different single-filament fineness produced separately are combined, and one process is added.

Embodiment 1

[0050] With a total fineness of 470dtex, 96 filaments, a boiling water shrinkage rate of 8.0%, and a flatness of the monofilament section of the nylon 66 raw yarn of 3.3, after weaving through flat weaving with a water jet loom, shrink processing with boiling water, and in Drying was carried out at 110° C. to obtain a fabric with a warp density of 49 threads / inch and a weft density of 49 threads / inch. The properties of this base fabric were evaluated and are shown in Table 1.

Embodiment 2

[0052] With the total fineness of 350dtex, 144 filaments, 8.3% boiling water shrinkage, and 2.8 nylon 66 raw yarn, the flatness of the monofilament cross-section is woven with a water-jet loom, and then processed with boiling water shrinkage. Dry at 110°C to obtain a fabric with a warp density of 52 threads / inch and a weft density of 52 threads / inch. The properties of this base fabric were evaluated and are shown in Table 1.

Abstract

The invention relates to an air bag using backing fabric. It is made by weaving synthetic fiber filament and shrinkage machining. The synthetic fiber filament formed air bag using backing fabric contains odd-shaped cross section filament, and the flatness of its monofilament cross section is from one point five to five. Before the shrinkage machining the boiling water shrinkage of the synthetic fiber is from six percent to fifteen percent. According to the invention the air bag using backing fabric can be supplied which possesses light texture, low air permeability, and good economical efficiency.

Description

technical field [0001] The present invention relates to a base fabric for an airbag that is lightweight, has low air permeability, and is also excellent in economical efficiency. Background technique [0002] In recent years, as one of the spare parts for automobile safety, most automobiles are equipped with airbags. When a collision accident occurs, the sensor senses the impact, and the high-temperature and high-pressure gas is generated from the pressure pump, and the gas is rapidly expanded. Bag, so that when the body of the driver or co-passenger flies out in the direction of collision, it can prevent the head from hitting the steering wheel, windshield, door glass, etc., so the air bag can be used for protection. [0003] In the past, coated base fabrics coated with synthetic rubber such as chloroprene, chlorosulfonylated olefin, and polysiloxane were used on air bags. The reason is that these materials have heat resistance and air barrier properties (low Air permeabil...
