Abstract

The invention relates to an airbag fabric with high tensile strength and a production method thereof. The fabric is composed of filaments with the strength ranging from 7.9CN / dtex to 9.2CN / dtex, the filament is composed of 136 to 192 monofilaments, a cover factor of the fabric ranges from 2000 to 2500, and the warp-weft tensile fracture strength ranges from 600 to 900 N / cm. The invention further relates to the production method of the airbag fabric with high tensile strength.

Description

technical field [0001] The invention relates to a high tensile strength airbag fabric and a production method thereof. Background technique [0002] In recent years, with the improvement of people's awareness of traffic safety, the effectiveness of airbags has been recognized, and they have quickly entered the stage of practical application. After the vehicle collides, the airbag expands and expands in the vehicle in a very short time, thereby preventing the occupant from moving due to the reaction force of the collision, absorbing the impact and protecting the occupant. [0003] Chinese patent application CN103306002A discloses a fabric for airbags with high density and high tensile strength, but the strength of the filaments used in this patent is 9.5CN / dtex, and the number of monofilaments is 65-128. For fabrics composed of filaments with more than 136 filaments and a filament strength of 7.9CN / dtex to 9.2CN / dtex, how to achieve high density and high tensile breaking str...
