Low permeability fabric and method of making same.

摘要

A strong, lightweight, thin, flexible fabric of low permeability comprising an uncoated woven cloth (10) is disclosed. The cloth (10) has a permeability of not more than 0.5 cubic centimetre of air per second per square centimetre of cloth at a pressure drop of 1.27 centimetres of water across the cloth, and may be calendered on both sides to reduce its permeability. The fabric is particularly suitable for use in the production of expansible passenger-restraint bags for motor vehicles.
