GAS-PERMEABLE MATERIALS CONTAINING LOW-STRETCHABLE FABRICS AND METHOD OF MANUFACTURE OF SUCH MATERIALS

摘要

FIELD: manufacture of gas-permeable materials containing layer of low-stretchable fabric and microporous coat for use in construction engineering. ^ SUBSTANCE: microporous coat contains composition of crystalline polymer and filler. Method of manufacture of gas-permeable material includes extrusion of coat on layer of low-stretchable material. Coat is made from composition of crystalline polymer and filler. Tension of non-woven material layer is increased. ^ EFFECT: enhanced strength or stiffness of non-woven material layers; facilitated procedure of process. ^ 29 cl, 2 ex
