FIELD: chemical industry; production of a laminar material of an increased tensile strength. SUBSTANCE: the offered laminar material may be used at manufacture of the absorbing items of personal hygiene, a protective clothing for the medical and industrial purposes, as well as the special working clothes. The laminar material includes at least one layer of inelastic polyolefin fibers of a spinneret method of production having the narrow molecular-mass distribution, and preferably formed of the polypropylene produced with the help a metalloceneous catalyst and a layer of a breathing film formed from polyolefin. According to the offered method of production of the laminar material a combination of the non-woven fabric of the spinneret method of production with the previously formed layer of a breathing film should be made within 1-30 seconds after forming the indicated non-woven fabric. The produced laminar material has an increased tensile strength, improved breathing capacity and barrier characteristics. EFFECT: an increased tensile strength and improved breathing capacity and barrier characteristics. 24 cl, 3 dwg, 4 tbl |
