Title: Improvements relating to the maintenance of moisture content in textiles
IPC: D06M11/79
Filed: 1935-08-19
Abstract: Textile materials are subjected to a treatment wherein silica gel is deposited on the materials in such quantity that the moisture content of the treated materials remains substantially constant under the varying atmospheric conditions encountered in storage, manufacture, or transit, but that the characteristic properties of the materials are not affected.  Deposition may be accomplished by application of an alkaline silicate to a fabric either by immersion or by brushing, followed by a treatment with acid to precipitate the silica gel.  The gel may be obtained from water-glass or other soluble silicate.  The silica gel on the textiles and in the cells of the fibres maintains equable moisture conditions and by sealing the fibre cells prevents absorption or loss of water under varying atmospheric conditions. Reference has been directed by the Comptroller to Specification 357,773.
