' To all whom it may concern:
Be it known that I, THOMAS J OHN IRELAND the King of Great Britain a resident of Vest Didsin the county of Lancaster, England, have inve ted certain new and useful Improvements in the Fireproofing of Textile Fabrics and other Porous Articles, of which the following is a specification.
This invention relates to the fireproofing of textile fibers and fabrics and other porous or absorbent substances or articles, and is an improvement in or modification of the invention described in the specification 0 Patent No. 1,225,414.
In the specification of the said patent, there is described, inter alia, a treatment with acid alkali carbonate liquor of textile fibers andfabric's and other porous or absorbent substances or articles (hereinafter in this description and the appended claims for convenience referred to as fabric) which have been previously impregnated with suitable alkaline aluminates. The said treatment consists in immersing the aluminated fabric in acid alkali carbonate for a suitable time.
I have now found that I am able to obtain the desired effect of fixing the fireproofing body in the fabric by simply wetting the aluminated and preferably dried fabric with acid alkali metal carbonate solution and then subjecting it to a treatment at about 100 C. for a suitable time with steam or with steam and carbon dioxid gas. When treating the alu'minated and dried fabric with acid alkali metal carbonate solution, I take care to maintain the latter in an acid condition by the addition of further acid alkali metal carbonate, or by passing in to it carbon dioxid gas either in the wetting out machine or in a subsidiary vessel; a circulation of liquor being suitably kept up between the wetting out machine and the subsidiary vessel in the latter case. Before wetting the aluminated fabric with acid alkali metal carbonate solution, I may subject it to intermediate treatment, as described in the specification of Patent No. 1,225,414.
The following is an example of the manner in which I may carry out this alternative process forming the present invention Flannelette is impregnated with sodium aluminate, as described in the specification of the aforesaid patent, and dried. The
and Ireland, and
Specification of Letters Patent.
Patented Nov. 22, 1921.
Application filed October 30, 1917. Serial No. 199,260.
aluminated fabric is then wetted out suitable known means with hot condried y centrated acid sodium carbonate solution and squeezed to remove excess of liquor. The fabric is then subjected by known means to a treatment with steam at about 100 C. for a suitable time, after which it may be washed and suitably dealt with in any desired manner.
According to a modification, the aluminated fabric, after being wetted out with the acid sodium carbonate solution and squeezed to remove the excess of liquor, is subjected to a treatment with steam and carbon dioxide gas at about 100 C. for a suitable time.
I may carry out the herein described operation in or by any convenient means and in any convenient manner, and confine myself to the precise details of the operations hereinbefore mentioned, which are given merely by way of example.
\Vhat I claim as my invention and desire to secure by Letters Patent is 1. The process of rendering fibrous or'absorbent materials and the like less inflammable, which consists 'in first treating said materials with an aluminate of an alkali metal, then subsequently treating said materials with a solution containing so ium bicarbonate, terials to heat.
2. The process of rendering fibrous or absorbent materials and the like less inflammable, which consists in first treating sai materials with an aluminate of an alkali metal, then subsequently treating said materials with a solution containing sodium bicarbonate, and finally subjecting said materials to steam.
3. The process of rendering fibrous or absorbent materials and the like lessinflammable, which consists in first treatin said materials with an aluminate of an al ali metal, then subsequently treating said materials with a solution containing so ium bicarbonate, and finally subjecting said materials to steam at about 100 C.
4:. The process of rendering fabrics and the like less inflammable, which consists in treating the fabric with an aluminate of an alkali metal, drying the same, treating the dried fabric with an acid alkali metal carbonate solution, and then subjecting the fabric to the action of steam.
