Abstract:
Composite product of adjacent interconnected layers of heat shrinkable fibers, made by heat shrink processing of interconnected such layers of differential shrinkage properties.
Abstract:
A planar substrate has a moisture activated shrinking filament applied thereon. When wetted, the shrinking filament shrinks and causes the planar substrate to gather and pucker. The planar substrate with the filament thereon may be compressed into a compact shape when in a dry state.
Abstract:
There is described a synthetic textile support for bituminous sheaths, particularly for the coating of roofs. The textile support consists of two layers (1, 2) of non-woven lap of polyester fibres, between which there is interposed a plurality of continuous polyester threads (3) arranged parallel to one another in the longitudinal direction of the textile support.
