Abstract
Abstract A composite textile is formed of a first non-woven needled textile layer, a second microporous film layer, and a discontinuous adhesive layer between the first and second layers to fix the first and second layers together. The first non-woven needled textile layer has a thermo-stable fiber basis, while the second microporous film layer is inflammable and is impermeable to liquid, but permeable to water vapor. Protective clothing is formed having an outer textile layer and a lining with an insert mounted loosely between the outer textile layer and lining. The insert comprises a composite textile as described above with the first layer of the composite textile facing towards the lining. The composite textile can also be used in a seat with the composite textile placed between an outer textile layer and the foam elements of the seat, with the first layer of the composite textile facing towards the foam elements of the seat.
