FIELD: textiles, paper.
SUBSTANCE: method of production of sealed seams of garments. The invention relates to the light industry, namely to manufacturing of special waterproof clothing. The method of production of sealed seams of garments comprises applying at stitching of the material layers on the surface of the sewn seam of the aqueous polymer dispersion. The dispersion is used as an aqueous polyurethane dispersion based on the aromatic polyurethane with a viscosity at 100-300 mPa·s·at 25°C. The polyurethane dispersion is applied to the surface of the sewn seam with an inlay on both its sides.
EFFECT: simplifying the technological process, increasing the adhesive strength of the sealing layer to the material by 132-168%, increasing the water-resistance of the seam by 18-52%, reducing the seam stiffness by 17%.
