Embodiment Construction
[0018] The present invention will be described in detail below through specific embodiments. The embodiments are helpful to the understanding and implementation of the present invention, and are not intended to limit the present invention; the protection scope of the present invention is defined by the claims.
[0019] The warp and weft elongation deviation minimization process of the airbag fabric of the present invention, the schematic diagram of its process flow is as follows figure 1 , the gray fabric is ①refined by chemicals, ②rinsed, then ③extruded and filtered, ④steam drying roller is closed, and enters the oven for heat treatment. After ⑤overfeed adjustment, ⑥width and temperature adjustment, and finally ⑦cooling, the fabric is formed .
[0020] The airbag fabric is sorted through the following steps, and the warp and weft elongation deviation of the molded fabric can meet the minimum requirement. The method includes:
[0021] 1. Washing and refining: the fabric is wa...
