or ERKELEY; oamronnra PROCESS FOR FIREPROOFING AND WATERPROOFING TEXTI LES No Drawing.
Application filed July 24, 1929. Serial No. 380,742.
(GRANTED UNDER THE AC'I. OF MARCH 3, 1883, AS AMENDED AIPRIL 30, 1928; 370 0. G. 7 57) This application is made under the act approved April 30, 19:28, and the invention herein described may be manufactured and used by or for the Government for governmental purposes without payment to us of any royalty thereon.
We hereby dedicate the invention herein described. to the free use ofthe public, to take effect upon the granting of a patent to us.
This invention relates to a combined process for fire-proofing and waterproofing fabrics and leather goods and is particularly adapted for use by persons engaged in spraying chemicals such as chlorates, perchlorates, per-sulphates etc... which form combustible mixtures with clothing materials made of cotton, Wool or silk or with leather goods.
The invention comprises a method first described by Perkins for the initial fireproofing process and combines with it'tre'atment of the material to be protected by means of a waterproofing process namely a natural asphalt dissolved in a rapidly volatile solvent.
A fireproofing or a waterproofing process alone does'not give adequate protection if cloth is subsequently sprayed with or soaked in sodium chlorate. The combined process however renders the fibre.'fla1ne-proof and then provides an impermeable layer about the fibre which prevents the chemical in water solution from soaking into the fibre.
Cloth treated by the combination process is absolutely spark-proof, cannot be ignited by friction and allows the surface chemical to burn off slowly Without a rapid burning of the cloth.
The combined process is described as follows: (1) Material is thoroughly soaked in a Tw. (Twaddells h'ydrometer degree readings, or 27 Baum) solution of sodium stannate, and then squeezed (squeezing is very important) and-dried. The material is then passed through a 15 Tw. (or 10 Baum) solution of ammonium sulphate, again r squeezed and dried Without rinsing. A further treatment with cold water is advised in order to remove (2) The material is dried again andthen thorougly soaked in a gilsonite-benzene solution to 1 gram of gilsonite per 100 cc. of
in a proportionate the soluble sodium sulphate.
commercial coal tar benzene). The cloth is again squeezed. and air dried until the excess solvent has v'olatilized. Cloth that is being wornor subjected to any frictional action may require a further waterproofing treatment. One treatment with the fireproofing materials is sufficient. Textiles so treated may be washed repeatedly without impairing the waterproofing or fireproofing processes. Gilsonite' is a natural asphalt which is. mined in Utah and is available in unlimited amounts.
\Ve claim:
A. process for fireproofing and waterproofing fibrous and other materials con- .sisting of immersing the materials in a 45 Tw. solution of sodium stannate, squeezing and drying the materials, soaking the said materials in a 15 Tw. solution of ammonium sulphate, squeezing and drying the said materials, removing the soluble sodium sulphate by dipping in cold water, drying and then thoroughly soaking the said materials solution of not more than 1 gr. of gilsonite in 100 cc. of benzene, and squeezing and air drying the said materials until the excess solvent has volatilized.
