Method of producing fabric for airbag
First Claim
1. A method for producing a woven fabric for an air bag composed of synthetic fibers as a warp thread and weft thread, the method comprising:
- 1) weaving with high tension warp threads at 0.20 cN/dtex to 0.65 cN/dtex in a water jet loom,2) carrying out a washing treatment step at 80°
C. or lower or not carrying out a washing step,3) drying at a temperature of 110°
C. or lower, and4) carrying out a calendering processing,wherein the contact angle of a circumscribed circle at intersecting sections where the warp thread and weft thread come in contact in a cross-section of the fabric is 80°
or more in both the warp thread direction and the weft thread direction, andwherein the radius of a circumscribed circle is 380 μ
m or less in both the warp thread direction and the weft thread direction.

Abstract
The purpose of the present invention is to provide a method of producing a fabric for an air bag that, during high-pressure deployment at high speed, maintains low air permeability as an air bag and is capable of maintaining the low air permeability even after exposure to heat. This method of producing a fabric for an air bag comprises the steps of: 1) weaving with high tension warp threads at 0.20 cN/dtex to 0.65 cN/dtex in a water jet loom, 2) carrying out a washing treatment step at 80° C. or lower or not carrying out a washing step, 3) drying at a temperature of 110° C. or lower, and 4) carrying out calendering processing.
