Abstract

A fabric with a small bias filling rate for an airbag is characterized by consisting of a ground stitch and selvage stitches positioned on two sides of the ground stitch, wherein the ground stitch and the selvage stitches are formed by adopting two kinds of filaments with different initial moduluses; the difference ratio of the initial modulus of high initial modulus filaments for the ground stitch to the initial modulus of low initial modulus filaments for the selvage stitches is 15.0-40.0 percent; and the small bias filling rate of the fabric is not more than 2.0 percent. The fabric for the air bag, which is disclosed by the invention, has the advantages of small bias filling rate, excellent tensile failure and tearing property, favorable size stability and low cost.

Description

technical field

[0001] The present invention relates to a fabric for an airbag with a small skewness. Background technique

[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 is: after a collision, quickly open a bag filled with gas between the occupant and the interior components, let the occupant pounce on the airbag, and absorb the kinetic energy of the passenger through the discharge throttling damping of the airbag, making the violent crash Collisions inside the car are buffered to protect passengers.

[0003] At present, water-jet ...

Examples

Embodiment 1

[0039] The texture of the airbag fabric is made of nylon 66 raw yarn with a total fineness of 350dtex, 136 filaments, and a circular cross section. The tensile breaking strength is 8.3cN / dtex, and the tensile breaking elongation is 21.5%. The modulus is 55cN / dtex. The two sides of the fabric for airbags use nylon 66 raw yarn with a total fineness of 350dtex, 136 single filaments, and a circular cross section. The tensile breaking strength is 8.3cN / dtex, and the elongation at break is 20.0%. The amount is 48cN / dtex, and the number of roots is 82. After the plain weave fabric is woven with a rapier loom, the temperature of the scouring tank is 80±5°C, the temperature of the washing tank is 65±5°C, the heat setting temperature is 150±10°C, and the speed is 30 m / min. The all-in-one machine performs post-processing to obtain a fabric with a warp density of 60 threads / inch and a weft density of 60 threads / inch. The characteristics of this base cloth were evaluated and are shown in...

The tensile breaking strength is 8.3cN / dtex, and the tensile breaking elongation is 21.5%. Modulus 60cN / dtex. The fabric on both sides of the airbag fabric is made of nylon 66 raw yarn with a total fineness of 470dtex, 68 single filaments, and a circular cross-section. The tensile breaking strength is 8.3cN / dtex, and the tensile elongation at break is 21.5%. Modulus 45cN / dtex. The root number is 50. After the plain weave fabric is woven with a rapier loom, the temperature of the scouring tank is 80±5°C, the temperature of the washing tank is 65±5°C, the heat setting temperature is 170±10°C, and the speed is 30 m / min. The all-in-one machine performs post-processing to obtain a fabric with a warp density of 49.5 threads / inch and a weft density of 49.5 threads / inch. The characteristics of this base cloth were evaluated and ar...

[0043] The airbag fabric is made of raw polyester yarn with a total fineness of 700dtex, 105 filaments, and a circular cross-section. The tensile breaking strength is 8.0cN / dtex, and the tensile elongation at break is 21.5%. The amount is 65cN / dtex. Both sides of the fabric for airbags are made of raw polyester yarn with a total fineness of 700dtex, 105 single filaments, and a circular cross-section. The tensile breaking strength is 8.0cN / dtex, and the tensile elongation at break is 23.0%. The modulus is 40cN / dtex, and the number of roots is 40. After the plain weave fabric is woven with a rapier loom, the temperature of the scouring tank is 80±5°C, the temperature of the washing tank is 65±5°C, the heat setting temperature is 180±10°C, and the speed is 30 m / min. The all-in-one machine performs post-processing to obtain a fabric with a warp density of 41 threads / inch and a weft density of 41 threads / inch. The characteristics of this base cloth were evaluated and are shown in...
