Embodiment 1

[0029] The warp and weft yarns adopt the polyester flat filaments whose fineness is 235dtex, the number of monofilaments is 72, and the flattening rate is 1.6, and the above-mentioned filaments are woven with a water jet loom to obtain a warp density of 55 threads / inch, weft To the plain weave fabric with a density of 55 pieces / inch, use the doctor blade method to coat the organic solvent-free silicone resin on the above fabric, and then carry out the calendering pressure at 100Kg / cm, speed at 10m / min, and temperature at 100°C After calendering and heat setting, the coating weight is 10g / m 2 low-coated fabric for airbags. The properties of the fabric were evaluated and are shown in Table 1.

Embodiment 2

[0031] The warp and weft yarns adopt a denier of 350dtex, a number of single filaments of 72, and a polyester flat filament with a flattening rate of 2.5. The above-mentioned filaments are woven with a water jet loom to obtain a warp density of 51 threads / inch, weft To a plain weave fabric with a density of 51 threads / inch, apply an organic solvent-free silicone resin on the above-mentioned fabric using a doctor blade method, and then perform the calendering at a calendering pressure of 120Kg / cm, a speed of 20m / min, and a temperature of 150°C. After calendering and heat setting, the coating weight is 12g / m 2 low-coated fabric for airbags. The properties of the fabric were evaluated and are shown in Table 1.

Embodiment 3

[0033]The warp and weft yarns adopt a denier of 470dtex, a number of single filaments of 136, and a polyester flat filament with a flattening rate of 2.5. The above-mentioned filaments are woven with a water jet loom to obtain a warp density of 53 threads / inch and a weft density of 2.5. To a plain weave fabric with a density of 53 threads / inch, apply an organic solvent-free silicone resin on the above-mentioned fabric using a doctor blade method, and then perform the calendering at a calendering pressure of 150Kg / cm, a speed of 35m / min, and a temperature of 200°C. After calendering and heat setting, the coating weight is 15g / m 2 low-coated fabric for airbags. The properties of the fabric were evaluated and are shown in Table 1.

Abstract

The invention discloses a kind of coating fabric for air bags and a production method thereof. The fabric is composed of weft yarns and warp yarns, which are polyester flat yarns with a flatness rate of 1.6 to 2.5, the coating amount of the fabric is 10 to 15 g/m2, and the capacity of the fabric is 1300 to 1500 cm3. The coating fabric for air bags has the characteristics of high tensile strength, good capacity, low air permeability, and low production cost.

Description

technical field [0001] The invention relates to a coated fabric for an airbag and a production method thereof. Background technique [0002] In recent years, with the rapid development of the automobile industry and the development and construction of expressways, the driving speed of automobiles has become faster and faster, and traffic accidents have occurred more frequently. Therefore, the safety of automobiles has become particularly important, and subsequently Driven the development of airbags. Fabrics used for airbags need to have the following characteristics: low air permeability to achieve sufficient deployment of the airbag at the time of collision, high strength and high heat resistance to prevent damage or rupture of the airbag itself, and flexibility (flexibility) to reduce damage to the occupant the impact caused. However, in the process of inflating and opening the airbag, the high temperature and high pressure it endures puts forward very high requirements ...
