Problems solved by technology

However, until now, the identification information of the cloth roll has only been associated with the airbag bag body by using the production ledger, and has not been displayed on the part of the cut airbag sewing cloth itself.
Therefore, there is a possibility of misuse at the time of assembly. In addition, it takes labor / time to track the production history from the fabric of the airbag body after sewing, and there is also a problem that the history cannot be completely determined accurately.

Embodiment 1

[0087] As the weaving yarn, a polyhexamethylene adipamide fiber having a fineness of 470 dtex and 136 filaments was used. The tanδ(max) of this fiber was 0.075, the Tmax was 122°C, and the ratio S was 0.00061 [1 / °C]. As a warp yarn, it is arranged in parallel without twisting and sizing to make a warp beam. For the weft yarn, it is wound without twist and size, and supplied directly from the bobbin. A plain weave is produced using a water jet loom. The entry reed of warp yarn is 2 / reed teeth. The obtained fabric was dried at 60° C. without refining so that the moisture content of the fabric was 3%. Next, heat-setting processing was performed using a pin tenter under the conditions of a heating temperature of 200° C. and a 1-minute dwell, with an overfeed of 0% and a neck-in of 2%. The fabric density of the finished fabric is 53.0 / 2.54cm in warp and weft. The oil content was 0.15% by weight.

[0088] For the cloth, an inkjet printer utilizing 60 micron nozzles used ethano...

Embodiment 2

[0090] In Example 1, heat calendering was performed instead of heat setting with a pin tenter. The hot rolling process was performed at a feed rate of 18 m / min, a metal roll temperature of 200° C., and a pressure of 600 N / cm. Regarding the upper and lower calender rolls that sandwich the fabric, the upper metal roll for heating has a diameter of 12 cm, and the lower roll has a paper surface of 24 cm in diameter, and the surface speed is the same speed up and down. The Shore D hardness of the paper roll surface was 65. The fabric density of the finished fabric is 53.0 / 2.54cm in warp and weft. The oil content was 0.15% by weight.

[0091] A barcode was printed by inkjet in the same manner as in Example 1 on the surface smoothed by heating calender roll processing. The exudation index N was 0.1, which was good. The print quality evaluation of the printed surface by the barcode checker (opening diameter 10 / wavelength 660) was rank A-3.6, and it was good. The reading printing ...

Embodiment 3

[0093] In Example 1, after weaving and drying, at 20g / m 2 Finishing is performed by applying two-component curable silicone with no color pigment added, and vulcanizing by heating at 180°C for 2 minutes. The fabric density adjustment on the loom was carried out, and the fabric density of the finished cloth became 49.0 warp and weft averages / 2.54cm. The oil content was 0.15% by weight.

[0094] A barcode was printed on the non-coated surface by inkjet in the same manner as in Example 1. The exudation index N was 0.8. The print quality evaluation of the printed surface by the barcode checker (opening diameter 10 / wavelength 660) was rank B-2.8, and it was good. The read print quality of the non-printed surface was grade B-2.5, good.

Abstract

The object of the present invention is to provide a fabric for airbag manufacturing that displays raw material information, specification marks, individual identification information, etc. The airbag fabric of the present invention is characterized in that production information is directly printed and marked on the fabric by inkjet.

Description

technical field [0001] The present invention relates to a fabric for an airbag used as a bag body of an airbag device which is an occupant protection device at the time of vehicle collision. Background technique [0002] In order to alleviate the impact on the human body in a collision accident of vehicles such as automobiles, airbags are installed in vehicles. As airbags that use gas to inflate in the event of a collision and absorb the impact on the human body, in addition to airbags for the driver's seat and passenger's seat, air curtains, side airbags, knee airbags, rear airbags, etc. are increasingly installed in vehicles. to protect passengers. Furthermore, in order to protect pedestrians, airbags installed so as to be inflated outside the passenger compartment of vehicles have also been proposed, and the installation of them is expanding. [0003] The front impact airbag is also given the status of an auxiliary restraint device added to the seat belt, which is the m...
