Problems solved by technology

[0006] The above-mentioned patents do not describe the warp and weft shrinkage of the airbag fabric and the standard deviation of the warp and weft shrinkage, and do not involve whether the fabric has high slip resistance, so it is not possible to know well when the base fabric for the airbag is deployed. whether the part slips very little
[0007] In the patent WO2005 / 045123, a method of coating a silicone composition on a fabric carrier and crosslinking is described. This method brings about an increase in cost and cannot meet the requirements of the automotive industry for cost reduction.
U.S. Patent 09 / 326368 proposes to use welded seams to improve the slip resistance between the sewn part and the base fabric, but because the fabric beads are not completely firm, the airtight structure produced by the polymer beads is damaged
Patent WO2001 / 023219 applies a new method of welding, reinforced with stitched seams, which can improve the resistance to slippage, but since this method usually involves bringing the film on the underside of the fabric into contact with the fabric treated with a second film And under high-frequency energy, thus forming polymer beads at the attachment point between the two layers of fabrics, increasing the subsequent process, resulting in increased costs

Embodiment 1

[0072] Nylon 66 raw yarn with a total denier of 470dtex, 72 single filaments and a circular cross-section was used, with a breaking strength of 39.5N and a breaking elongation of 23.5%. After the warping of the sample warping machine, between the back beam and the back weaving mouth during weaving, the tension difference rate between every 10 continuous warp yarns (measurement of 10 sets of data) is between 7.5% and 30%, and it is woven with a water jet loom. After the plain weave fabric, dry it in a dryer at a temperature of 80 ± 2°C and a speed of 10 ± 1 m / min to obtain a fabric with a warp density of 53 threads / inch and a weft density of 53 threads / inch. The properties of the base fabric were evaluated and shown in Table 1 and Table 3.

Embodiment 2

[0074] Nylon 66 raw yarn with a total denier of 470dtex, 72 single filaments and a circular cross-section was used, with a breaking strength of 39.5N and a breaking elongation of 23.5%. After warping by warping machines in batches, between the back beam and the back weaving mouth during weaving, the tension difference rate between every 10 continuous warp yarns (measure 10 sets of data) is between 10% and 40%, and weaving with a water jet loom After the plain weave fabric is formed, it is dried in a dryer at a temperature of 80±2°C and a speed of 10±1 m / min to obtain a fabric with a warp yarn density of 53 yarns / inch and a weft yarn density of 53 yarns / inch. The properties of the base fabric were evaluated and shown in Table 1 and Table 3.

Embodiment 3

[0076] Nylon 66 raw yarn with a total fineness of 350dtex, 136 single filaments and a circular cross section was used, with a breaking strength of 30.6N and a breaking elongation of 23.5%. After warping by warping machines in batches, between the back beam and the back weaving mouth during weaving, the tension difference rate between every 10 continuous warp yarns (measure 10 sets of data) is between 10% and 40%, and weaving with a water jet loom After the plain weave fabric is formed, it is dried in a dryer at a temperature of 80±2°C and a speed of 10±1 m / min to obtain a fabric with a warp yarn density of 59 yarns / inch and a weft yarn density of 59 yarns / inch. The properties of the base fabric were evaluated and shown in Table 1 and Table 3.

Abstract

The invention discloses a textile fabric for an air bag and a production method thereof. The textile fabric for the air bag is produced by weaving synthetic fiber filaments; and the ratio of the standard deviation of the reversion to the average value of the reversion of at least one of every ten continuous wraps and every ten continuous wefts is 1.5 to 15.0 percent. The invention can provide the textile fabric which can maintain the fundamental performances and has small slippage on sewing parts when the air bag is unfolded.

Description

Technical field: [0001] The present invention relates to a fabric for an airbag, and more particularly, to a fabric which maintains basic properties and has a small slip of the sewn part when the airbag is deployed. technical background: [0002] In recent years, with the rapid development of the automobile industry and the development and construction of expressways, the speed of automobiles has become faster and faster, and traffic accidents have occurred more frequently, so the safety of automobiles has become particularly important. As one of the safety spare parts of automobiles, the installation rate of airbags increases rapidly with the improvement of people's safety awareness. The basic working process of the airbag: after a collision, a gas-filled bag is quickly opened between the occupant and the interior components, allowing the occupant to pounce on the airbag. The kinetic energy of the passengers is absorbed through the exhaust throttling damping of the airbag,...
