Claims7
A method for manufacturing a base fabric for an air bag, comprising:
- applying an aqueous resin composition containing a pigment, a reactive compound and a water-dispersible thermoplastic resin to a woven/knitted fabric made of synthetic fiber to form a coated fabric, and
- subjecting the coated fabric to a thermal treatment,
- wherein the water-dispersible thermoplastic resin comprises a polyamide, the pigment is dispersed in water using a surfactant, the surfactant contains a hydroxyl group, and the number-average functional group number of the reactive group in the reactive compound is 2 or more.
A base fabric for an air bag, comprising:
- a resin composition containing a pigment and a thermoplastic resin applied to a woven/knitted fabric made of synthetic fiber in an amount of 0.1 to 8.0 g/m2, the thermoplastic resin comprising a polyamide,
- wherein color change rate before and after application of water drops calculated by the following formula (I) is 10% or less:
- Color change rate=(|L* value after the application−L* value before the application|2+|a* value after the application−a* value before the application|2+|b* value after the application−b* value before the application|2)1/2/[(L* value before the application)2+(a* value before the application)2+(b* value before the application)2]1/2×100 Formula (1).
