FIELD: manufacturing technology.
SUBSTANCE: invention is aimed at methods for producing stretchable elastic laminar materials with improved properties. Present invention is aimed at methods for production of laminar materials fabric-elastomer with uniform fabric destruction in extension of laminar material by 50 % or even by 100 % or more at least in one of machine direction (MD) or crosswise direction (CD). In particular, it has been found that by weakening one or more layers of cellulose material of elastic laminar material before, during or after lamination or binding and, in particular, fabric based on paper laminate material fabric-elastomer, laminar material acquires a fabric-like appearance and becomes soft on touch similar to conventional elastic nonwoven laminar materials.
EFFECT: obtained elastic laminar materials have improved mechanical strength.
