More specifically, the invention relates to an airbag while maintaining the mechanical characteristics of the airbag. TECHNICAL FIELD The present invention relates to an airbag base fabric and an airbag, which have less misalignment at the time of sewing.

ようになってきている。2. Description of the Related Art In recent years, various airbags have been developed in order to ensure the safety of occupants in the event of an accident of various transportation means, especially automobiles. I'm advancing. In particular, driver-side airbags and passenger-side airbags are almost completely mounted on passenger cars.

Elastomer resin such as synthetic rubber such as chloroprene, chlorosulfonated olefin, and silicone to improve heat resistance, flame retardancy, air barrier properties, etc. on plain fabrics using tex nylon 6.6 or nylon 6 filament yarn Was applied, and the base fabric laminated was cut and sewn into a bag.

った。[0004] However, when these elastomer resins are applied and laminated, a coating method such as knife coating, roll coating, and reverse coating is generally employed. Usually, in the case of a chloroprene elastomer resin, 90 to 120 g / m 2 is applied to the surface of the base fabric, so that there is a problem that the thickness is increased and the package volume is increased also in terms of storability. In the case of a silicone elastomer resin having more excellent heat resistance and cold resistance than a chloroprene elastomer resin, the application amount is 40 to 60 g / m 2 and the weight is reduced. Is enough
Another problem is that it is difficult to fold the bag when storing it in a package. Further, the steps of applying and laminating the elastomer are complicated, and there is a problem in productivity.

検討が進められている。Therefore, in recent years, airbags using non-coated base fabrics have been receiving attention in order to solve such problems. As a corresponding technology, a high-density non-coated airbag made of a polyamide fiber fabric such as nylon 6.6 or nylon 6 or a polyester fiber fabric has been studied.

With the revision of 08, the dual inflator is being studied. Since this inflator is a two-stage deployment system, the gas output in the second stage becomes larger than the output of the conventional inflator, As a result, there is a demand for reducing the misalignment between the sewing thread and the base cloth of the sewing portion constituting the airbag (hereinafter referred to as a "sewing portion eye misalignment"). In other words, there is a demand for improving the eye gap. In view of this point, for example, Japanese Patent No. 2950954 discloses a non-coated base fabric using a yarn having a total fineness of 300 to 400 dtex, but it is hard to say that the deviation of the sewing portion is sufficiently small. Japanese Patent Application Laid-Open No. 8-2359 discloses that the background cover factors are both 900 to 1400.
An airbag base fabric is disclosed in which the amount of residual oil agent adhered and the slip-off resistance of the woven fabric are specified, but it is difficult to say that it is sufficient to satisfy the deviation of the sewing portion.

縫製部目ズレをおこしにくくなる。[0011] In the airbag base fabric of the present invention, it is essential to attach a functional compound for improving the misalignment on at least one surface of the woven fabric in order to reduce the misalignment of the sewing portion. By doing so, the yarn-yarn friction of the yarn constituting the woven fabric increases, and even when an external force is applied between the sewn yarn and the woven fabric in the sewn portion, the woven fabric structure is maintained,
It is difficult to cause deviation of the sewing area.

It is preferably from 0.1 to 3.0% by weight, more preferably from 0.4 to 1.0% by weight, based on the woven fabric. If the amount is less than 0.1% by weight, the effect of the anti-shearing property of the sewn portion is too small, and if it is more than 1.0% by weight, the anti-shearing property is good, but the woven fabric becomes hard. It also has an adverse effect on tear strength and flame retardancy.

る。Among them, a mixture of silicon dioxide and a silicone resin is preferred because it can improve the misalignment without deteriorating the flexibility and tear strength of the woven fabric. The mixing ratio of the silicon dioxide to the silicone resin is preferably from 1: 0.01 to 0.10 from the viewpoints of not only the misalignment but also the flexibility, tear strength and flame retardancy. When the ratio of the silicone resin is less than 0.01 with respect to the silicon dioxide, the fabric may not be flexible and the tear strength may be reduced. That is, by mixing 0.01 or more, it is possible to maintain the flexibility of the woven fabric and prevent a decrease in tear strength. When the ratio is larger than 0.10, the flame retardancy may be deteriorated.

It is preferable to use one having a value of 00 in terms of mechanical properties, low air permeability, and bag storability. When the cover factor is smaller than 1800, although the bag storage property is preferable, the mechanical properties are reduced and the air permeability is increased. A cover factor of more than 2300 is preferable in terms of low air permeability and mechanical properties, but is not preferable because the woven fabric becomes hard and poor in flexibility, which causes a problem in bag storage properties.
