FIELD: textile industry, in particular, structure of fabric and method for producing such a fabric.

SUBSTANCE: fabric is manufactured by interweaving of warp and weft threads, with weft threads being combined thread including polyurethane core making 0.5-5.0% by weight of fabric, and twisted layer. Fabric is composed of thermally stabilized filaments. Warp threads and twisted layer are made from cotton filaments. Surface density of fabric is 75-435 g/m2, with number of warp threads per 10 cm making 154-446 and number of weft threads making 150-481. Method involves providing mutual interweaving of weft and warp thread systems; performing chemical processing, dyeing, printing and providing final finishing. Thermal stabilization process is carried out at temperature of 170-1900C for 40-90 s immediately before preliminary chemical processing or dyeing or printing process or before final finishing procedure.

EFFECT: convenient use and reduced manufacture costs.
