Embodiment 1

[0055] Nylon 66 filaments with a total fineness of 470 dtex, 72 filaments, and a circular cross-section were used, with a breaking strength of 39.7N and a breaking elongation of 24.3%. After warping, the tension difference rate of every 10 continuous warp yarns between the back beam and the back weaving fell is 10%. After weaving into plain weave fabrics, and drying at 80°C, the warp yarn density is 53 yarns / inch, weft density of 53 / inch fabric. The characteristics of this base cloth were evaluated and are shown in Table 1.

Embodiment 2

[0057] Nylon 66 raw yarn with a total fineness of 470dtex, 136 strands, and a circular cross section was used, with a breaking strength of 40.3N and a breaking elongation of 24.1%. After warping, the tension difference rate of every 10 continuous warp yarns between the back beam and the back weaving fell is 35%. After weaving into a plain weave fabric and drying at 80°C, the warp yarn density is 53 yarns / inch. , The fabric with a weft density of 53 threads / inch. The characteristics of this base cloth were evaluated and are shown in Table 1.

Embodiment 3

[0059] Nylon 66 raw yarn with a total fineness of 350dtex, 72 strands, and a circular cross section was used, with a breaking strength of 28.9N and a breaking elongation of 23.2%. After warping, the tension difference rate of every 10 continuous weft yarns during weaving is 15%. After weaving into plain weave fabrics and drying at 80°C, the warp yarn density is 53 yarns / inch and the weft yarn density is 53 yarns / inch. inches of fabric. The characteristics of this base cloth were evaluated and are shown in Table 1.

Abstract

The invention discloses a fabric for an air bag and a production method thereof. The average value of ratios of the number of abnormal interweaved points to the total number of the interweaved pointsof each 10 continuous warp yarns and / or weft yarns is larger than or equal to 15 percent in the fabric. Tension difference exists between each 10 continuous warp yarns and / or weft yarns when the fabric is weaved. The invention provides the fabric for the air bag fabric, which can keep basic performance, and has small slippage of a sewed part when the air bag is unfolded as well as good receiving performance and low cost.

Description

Technical field: [0001] The present invention relates to a kind of fabric, more specifically the fabric used in making safety airbags. Background technique: [0002] In recent years, people have paid more and more attention to the safety of automobiles, and passive protection systems have become the focus of attention of consumers, government agencies and automobile manufacturers. As one of the safety components of automobiles, the installation rate of airbags is also increasing rapidly with the improvement of the safety awareness of drivers and passengers. Airbags are currently the most widely used passive protection device in the United States, and their use continues to increase in other countries. [0003] The airbag system consists of three main components: (1) crash sensor; (2) inflation source; (3) airbag. In the event of a car collision, the controller identifies and judges the intensity of the collision based on the acceleration signal sent by the sensor. When the...
