FIELD: composite materials.

SUBSTANCE: invention aims at manufacturing composite fabrics comprising substrate with one or several discrete polymer areas. At least some of them are formed from elastomeric thermoplastic composition transferred onto substrate from recesses formed in transferring roller. Discrete elastomer polymer areas can be utilized to impart elasticity to substrate or to control degree of elasticity of the substrate.

EFFECT: achieved flexibility in controlling elasticity of fabrics.
