Problems solved by technology

The patent mentions that the fabric needs to be finished by boiling water shrinkage and / or heat shrinkage, which will increase the cost and cannot meet the long-term development requirements of the automotive industry.
[0007] In Patent Publication No. CN1520476A, a method for weaving fabrics, more specifically airbag fabrics, the patent mentions "interlacing warp yarns provided by at least two warp beams", the loom structure used in this method More complex, difficult to control and will reduce production efficiency

Embodiment 1

[0029] The warp and weft yarns are all made of nylon 66 filaments with a total fineness of 350dtex, a number of 136, and a circular cross section. Water-jet loom is used to weave plain weave, and a yarn pressing bar is added under the sheet warp between the heald frame of the loom and the back beam of the loom. Wherein, the specific position of the yarn pressing rod is that the horizontal position is located at 40 cm away from the back beam; the upward pressing displacement is 4 cm away from the warp position line. A fabric with a warp density of 59 threads / inch and a weft density of 59 threads / inch was obtained. The physical properties of the obtained fabrics were evaluated, and the relevant physical properties are shown in Table 1.

Embodiment 2

[0031] The warp and weft yarns are all made of nylon 66 filaments with a total fineness of 350dtex, a number of 136, and a circular cross section. Water-jet loom is used to weave plain weave, and a yarn pressing bar is added under the sheet warp between the heald frame of the loom and the back beam of the loom. Wherein, the specific position of the yarn pressing rod is that the horizontal position is located at 45 cm away from the back beam; the upward pressing displacement is at 6 cm away from the warp position line. A fabric with a warp density of 59 threads / inch and a weft density of 59 threads / inch was obtained. The physical properties of the obtained fabrics were evaluated, and the relevant physical properties are shown in Table 1.

Abstract

The invention discloses a production method of fabric for a gas bag, which comprises the step of weaving. In the fabric weaving process, a presser bar is additionally arranged below lamella warp between the heald frame of a weaving machine and the back beam of the weaving machine. The fabric obtained by the invention has no need of after-treatment and has good flexibility, low gas permeability and high slip resistance.

Description

Technical field: [0001] The invention relates to a production method of a fabric for an airbag. Background technique: [0002] Currently, the number of motor vehicles on which airbags are installed as safety components is sharply increasing as users' awareness of safety increases. Airbags can protect motor vehicle users, including drivers and passengers, from traffic accidents such as crashes. For example, when a collision occurs, the sensor senses the impact, thereby activating the inflator to generate gas under high pressure and high temperature, and then quickly deploys the folded airbag to protect the user from the impact. The airbag is generally stored in a suitable place in the motor vehicle, such as the steering wheel , instrument panels, door frames, etc. [0003] So far, considering the slip resistance, air permeability, heat resistance, and flame retardancy of the airbag, various post-treatment methods have been used, such as: fabric calendering treatment, high-s...
