MATERIALS PROTECTING AGAINST BURNS Russian patent published in 2012 - IPC A41D19/15 

FIELD: personal use articles.

SUBSTANCE: in order to reduce burn injuries related to fire, protective clothes are required for specialist working in hazardous environments, where short-term exposure to fire is possible, for instance, for search and rescue works, and police. Protective outfit of employees exposed to such conditions shall provide for improved protection making it possible for its user to quickly and safety find a way out of a hazardous situation rather than fighting it. The method to reduce time of residual burning of a flammable fusible material to less than 20 seconds includes the following a) production of an outer textile material containing a fusible material and having an inner surface and an outer surface, b) production of a thermosetting material containing a mixture of polymer resin-expandable graphite, in which the expandable graphite is characterised with expansion equal to at least 900 mcm while heated to 280°C, c) application of the mixture of polymer resin and expandable graphite onto the inner surface of the outer textile material to form a thermosetting material, in which the outer surface of the outer textile material is exposed to flame action. A textile component contains an outer textile material containing a flammable fusible material, a heat-resistant convection barrier adhered to the flammable fusible material, and a thermosetting material containing a mixture of polymer resin and expandable graphite between the flammable fusible material and the heat-resistant convection barrier applied in a broken manner in the form of dots onto the heat-resistant convection barrier with surface coating by at least 80%, in which increased thickness of the textile composite makes at least 1 mm after a test for thickness variation. When optimal operation parameters are achieved for a user in environments characterised by impact of spontaneous immediate ignition, light, breathing, waterproof or water-resistant clothes are required that demonstrate improved protection against burns.

EFFECT: reduced burn injuries.
