| titleOfInvention | A process for impregnating thick textile products with latex under great hydraulic pressures |
| abstract | Thick textile products, such as jute boot soles, ropes, are impregnated with rubber by forcing latex into them at a pressure of 50-800 atmospheres. The latex is treated to increase its viscosity, and to stabilize it to reduce friction and prevent coagulation during impregnation. Gum arabic, tragacanth, karaya may be employed, but neutral saps of cactus, particularly Nopal cactus are preferred. Castor oil soap, with or without linseed or like oil, may also be added. Alcohol mixed with soap to prevent a tendency to premature coagulation, may be added to the latex to facilitate penetration. 5 per cent of waterglass prevents the latex from exploding. A gas generating substance such as ammonium carbonate is also added to the latex to enable water to escape from the interior on drying. A suitable mix consists of 80 parts of latex (60 per cent solids), 15 parts of Nopal cactus sap, 5 parts of castor oil soap, 3 parts of a 5 per cent solution of ammonia, 5 parts of alcohol in soap, 6 parts of waterglass, 6 parts of linseed oil, 4 parts of ammonium carbonate, 2 parts of sulphur, 6 parts of zinc oxide, 0,5 parts of "Vulcacit P," 0,5 parts of "Vulcacit 774," and 0,5 parts of diphenylguanidine. The fabric &c. must be free from acid, and is treated if necessary with sodium carbonate. When the impregnation, the pressure and time of which depends on the thickness and texture of the article, is completed, the surface is cleaned, alcohol is applied to form a coagulated skin, the p article is warmed to generate gas and drive off water, pressed to compact the rubber, and vulcanized. Specification 316,335, [Class 140, Waterproof &c. fabrics], is referred to. |
