Title:
METHOD FOR MANUFACTURING POLYESTER FABRIC FOR AIRBAG
Document Type and Number:
WIPO Patent Application WO/2016/052961
Kind Code:
A1
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 yarn, 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 firmness of an airbag fabric by effectively removing the sizing agent from the textile substrate after the weaving process is completely performed. The method of the present invention comprises: a step for applying a polyester-based sizing agent to polyester yarn; a step for manufacturing a textile substrate using the polyester yarn to which the sizing agent has been applied; a step for removing the sizing agent from the textile substrate under an alkali condition of pH 8 to 10; and a step for forming a coating layer on the textile substrate, from which the sizing agent has been removed, in order to enhance air-tightness.
