FIELD: textile industry, in particular, production of nonwoven warming lining material on the base of fluff-and-feather material. SUBSTANCE: nonwoven material has fluff-and-feather base secured with acrylic binder. Fluff-and-feather base has synthetic and/or natural filaments with linear density of 0.17-0.24 tex, with ratio of fluff-and-feather base and filament being within the range of 70:50 - 30:50. Acrylic binder used in an amount of 15-35% by weight of dry residue is spread in surface layers of nonwoven material, with amount of acrylic binder decreasing in the direction of middle part. Cotton and/or Dacron, Vynol, Nitron filaments may be used as additional filaments. Fluff-and-feather material and/or natural and synthetic filaments are loosened, mixed, treated with antistatic preparation and worked in carding machine to produce fabric, which is further treated at both sides with acrylic binder by sprinkler and dried. EFFECT: increased efficiency, improved heat-insulating qualities of material, wider operational capabilities and enhanced reliability in operation. 3 cl, 1 tbl |
