POROUS POLYMERS & FUSIBLE FILMS.

New fibers and new polymer coatings based on poly(vinyl chloride) and polyurethanes, together with specially developed processing and coating techniques, offer potential advantages where fabrics are to be subjected to a harsh environment. Thus the tensile strength, tearing strength and dimensional stability are imparted by the textile fabric, while environmental protection is provided by the coating. A particularly significant development area has been the evolution of porometric and other breathable coatings, based on polyurethanes, that can provide a great improvement in terms of the comfort of garments designed for foul-weather clothing.
