Woven and laid hybrid yarn structures of adjustable gas and/or liquid tightness, further processing thereof, textile sheet materials of predetermined gas and/or permeability, and use thereof

Abstract

Woven or laid structures comprising at least two systems of parallel threads, at least one of these thread systems having more than 10 threads per centimeter and comprising at least 10%, based on the thread system, of hybrid yarns comprising reinforcing filaments and lower melting matrix filaments composed of thermoplastic polymers. In such woven or laid structures, the matrix component can be melted to form textile sheet materials of adjustable gas and/or liquid permeability, which are especially useful for manufacturing airbags.
