Embodiment 1

[0025] The warp and weft yarns of the fabric layer of low air permeability one-time forming airbag are woven from high-strength polyester fibers, the density of warp and weft yarns is 500D, the density of warp yarn 1 is 440 / 10cm, the density of weft yarn 2 is 380 / 10cm, and the strength is 7.5g / D . Wetting layer 3 is added to the surface of the fabric. After the fabric passes through JFC-2: 0.5 parts, JFC-E: 0.6 parts, ERKANTOL ® NR: 1.2 parts, water: 97.7 parts, the liquid carrying rate of the fabric after passing through the press bar is 40%, and it is dried at 130°C Dry the fabric to form a wet layer3. The fabric is treated with a cylinder heat dryer at a temperature of 130° C. and a treatment time of 1.5 minutes. The fabric is calendered, the temperature is 100°C, the speed is 15m / min, the line pressure is 620 N / mm, the silicone coating is treated, the weight of the front and back coating is 45±3 grams per square meter, and the drying temperature of the coating is 175°C. ...

Abstract

The invention discloses a low-air-permeability one-time forming safety air bag which comprises double cloth. The edge of the double cloth is continuously bonded together, and a cavity can be formed inthe double cloth. A moistening layer evenly covers the fiber surface of the double cloth, and the moistening layer is manufactured through a moistening layer treatment agent. The moistening layer treatment agent comprises the following components including, by weight, 0.5-10 parts of fatty alcohol and ethylene oxide condensation compounds, 0.5-10 parts of fatty alcohol polyoxyethylene ether, 0.5-10 parts of fatty alcohol glycol ether and 70-97.5 parts of water. Each of the front surface and the back surface of the moistening layer is evenly coated with a coating. The invention further discloses a production technology of the above low-air-permeability one-time forming safety air bag. The low-air-permeability one-time forming safety air bag and the production technology of the above low-air-permeability one-time forming safety air bag have the beneficial effects that on the premise that the same pressure maintaining performance is reached, 23%-31% of the coating amount can be reduced,the use amount of the chemical raw material of organic silica gel is reduced, the cost is saved, and the production process is more environment-friendly.

Description

technical field [0001] The invention belongs to the technical field of automobile airbags, and in particular relates to a low-permeability once-formed airbag and a production process thereof. Background technique [0002] With the increasing penetration rate of automobiles, consumers' requirements for automobiles are not only satisfied with travel needs, but also pay more attention to the safety configuration of automobiles. The passive safety configuration of automobiles has attracted more and more attention from consumers. The deployment rate of one-shot airbags in automobiles is also increasing year by year. One-shot airbags are used to protect against side impacts or rollovers, so there are pressure-holding or airtight requirements for one-shot airbags. In the industry, the fabric is usually coated with silicone to make the fabric meet the required pressure retention or air tightness. The silicone coating of one-shot airbag fabric with pressure maintaining requirements...
