Embodiment 1

[0081] Utilize plain weaving, weave polyamide 66 fibers with a total fineness of 350dtex and 108 filaments (filament) with a water jet loom, then use boiling water shrinkage processing, and dry and finish at 110°C to obtain a warp density of 63 / 2.54cm and a weft density of 61 Roots / 2.54cm of fabric. Polyamide 6, polyethylene glycol-propylamine adduct (molecular weight 600) and adipic acid are adjusted at a molar ratio of 2.5:1:1, and the resulting polymer is made into a water-based resin with a solid content of 15%. 1 wt % of carboxymethyl cellulose was added to adjust the viscosity to 10 dPa·s (measured with a viscometer (Viscotester) VT-04F manufactured by Lion Corporation). Evaluation The amount of resin after applying this resin to the fabric by knife coating and drying it is 3 g / m 2 The properties of the fabric are shown in Table 1.

Embodiment 2

[0083] Using plain weaving, polyamide 66 fibers with a total fineness of 350dtex and 108 filaments were woven with a water jet loom, then processed by boiling water shrinkage, and dried and finished at 110°C to obtain a warp density of 59 threads / 2.54cm and a weft density of 59 threads / 2.54 cm of fabric. Adjust the polyamide 6, polyethylene glycol-propylamine adduct (molecular weight 1500) and adipic acid at a molar ratio of 2.5:1:1, and make the obtained polymer into a water-based resin with a solid content of 15%, which is roughly the same as that of the water-based resin. Add 1 wt % of carboxymethyl cellulose to adjust the viscosity to 8 dPa·s. Evaluation The amount of resin after applying this resin to the fabric by knife coating and drying it was 7 g / m 2 The properties of the fabric are shown in Table 1.

Embodiment 3

[0085] Using plain weaving, polyamide 66 fibers with a total fineness of 350dtex and 108 filaments were woven with a water jet loom, then processed by boiling water shrinkage, and dried and finished at 110°C to obtain a warp density of 59 threads / 2.54cm and a weft density of 59 threads / 2.54 cm of fabric. Polyamide 6, polyethylene glycol-propylamine adduct (molecular weight 600) and adipic acid were adjusted at a molar ratio of 2.5:1:1, and the resulting polymer was made into a water-based resin with a solid content of 10% (viscosity: 0.5dPa· s), evaluate the use of impregnation treatment to apply to the fabric and make the amount of resin after drying 7g / m 2 The properties of the fabric are shown in Table 1.

Abstract

To provide at a low cost a fabric for airbags, one of safety devices for automobiles, in which both edgecomb resistance and tear strength (factors affecting inflating properties of an airbag) are improved. Preferably, to provide a fabric for airbags which is capable of being recycled as easily as an uncoated fabric and a fabric for airbags which has self-extinguishing property. A fabric for airbags which comprises a synthetic fiber woven fabric and synthetic thermoplastic resin applied on at least one side of the synthetic fiber woven fabric, characterized in that, by applying the synthetic thermoplastic resin, both edgecomb resistance and tear strength of the synthetic fiber woven fabric become 1.3 times or more as large as respective values of the synthetic fiber woven fabric before applying the synthetic thermoplastic resin. Preferably, the fabric for airbags has low air permeability and self-extinguishing property, and is capable of being repelletized with ease.

Description

technical field [0001] The present invention provides a fabric for an airbag as one of automobile safety devices, which is low in cost and has improved slip resistance and tear strength which affect deployment performance. More preferably, the present invention provides a fabric for an airbag as one of automobile safety devices that has excellent restraint performance on the human body and can be easily recycled (recycle) like a non-coat cloth, and is self-extinguishing in flammability and has Fabric for low-ventilation airbags. Background technique [0002] In recent years, as one of the safety components of automobiles, the installation rate of airbags has increased rapidly. When a car crashes, the sensor (sensor) feels the impact, and the gas of high temperature and high pressure is generated from the inflator (inflator), and the gas makes the airbag rapidly explode. Unfolding, when the body of the driver or a passenger flies out in the direction of the collision, it esp...
