Abstract:
Disclosed is a method for manufacturing a polyester fabric for an airbag that can not only prevent or minimize the separation of a sizing agent, which is provided to a yarn through a sizing process, during a weaving process, but can also maximize a peel strength between a textile substrate and a coating layer to be subsequently formed thereon and lower the stiffness of an airbag fabric by effectively removing the sizing agent from the textile substrate after the weaving process is completed. The method of the present invention comprises: applying a polyester-based sizing agent to a polyester yarn; manufacturing a textile substrate with the sizing agent-applied polyester yarn; removing the sizing agent from the textile substrate under an alkaline condition of pH 8 to 10; and forming a coating layer on the sizing agent-removed textile substrate in order to enhance air-tightness.
Abstract:
A method of preparing a polyester fabric for an airbag is provided, and particularly, a method of preparing a fabric for an airbag by inserting a predetermined weave into a selvage to provide the whole fabric with uniform tension upon weaving a high-density fabric for an airbag using a polyester yarn is provided.
Abstract:
A machine for folding a side curtain airbag which has a simpler machine configuration and is more efficient than a fully automatic machine and that can fold a large-capacity side curtain airbag cushion of approximately 4.0 m in length to sufficiently secure quality stability, and a process for folding a side curtain airbag by using the same, are provided.
Abstract:
Disclosed is a side curtain airbag and an airbag system including the same. The side curtain airbag according to the present invention comprises an inflating part having gas inflation, a non-inflating part supporting the inflating part, and an adhered part constituting a boundary between the inflating part and the non-inflating part. The adhered part is coated with a seam sealant and sewed. The initial maximum pressure of the inflating part is 40 kPa or more when injecting a gas therein with an instant pressure of at least 10 bar, and the pressure after 6 seconds is 25 kPa or more. The side curtain airbag may optimize to apply the method of seam sealant coating and sewing on the adhered part constituting a boundary between the inflating part and the non-inflating part. Thus, it can keep the internal gas pressure of the airbag to the extent of protecting passengers safely at rollover.
