摘要

A flexible, impermeable, universally chemically resistant composite structure (10) which may be fabricated into protective clothing useful, for example, in the handling and clean up of hazardous chemicals is provided for, which composite structure (10) comprises a fabric substrate (11), and thermally-melt-bonded on both sides thereof, a coated film (12), which coated film comprises a PTFE film (13) having a thermoplastic fluoropolymer coating (14) on both sides thereof. Preferably, the fabric substrate (11) of the composite structure (10) has been treated with an antiwicking agent. A method for forming such composite structures is provided for, which method comprises thermally-melt-bonding a PTFE film (13) having a thermoplastic fluoropolymer coating (14) on both sides thereof to each side of a fabric substrate (11). Articles of protective clothing are also provided for which are fabricated from the subject composite structures.
