ABSTRACT:
The disclosure embraces an inflatable flat tubular fabric which is coated on its outside surfaces with synthetic rubber or plastic and is constructed by weaving the fabric in tubular form with basic threads having a given tensile strength with the two layers of the fabric being joined together by auxiliary threads which have a substantially lower tensile strength than the basic threads so that, when the fabric is inflated, the auxiliary threads will be broken to permit expansion of the fabric to its full volume capacity.
