No 24,593 A.D. 1910
Date of Application, 22nd Oct., 1910
Complete Specification Left, 24th Apr., 1911 – Accepted, 14th Sept., 1911

PROVISIONAL SPECIFICATION
An Improved Composition for Cleaning and Water-proofing Textile and other Fabrics or Materials.

We, FRANCIS STEVENSON, of Lawside Dye Works, Dyer and Bleacher, and GEORGE SUTHERLAND HAMILTON. of 13, Erskine Street, Manufacturing Chemist, both in Dundee, in the County of Forfar, do hereby declare the nature of this invention to be as follows : –

This invention relates to the manufacture and application of a composition or compound for cleaning and water-proofing textile fabrics, felt, buck-skin and the like, the composition being particularly applicable fpr treating the web equipments used by the army and territorial forces.
The improved composition is composed of natural or artificial coloured pigments or pigments or colouring matter, powdered soap soluble in water, and a metallic salt or metallic salys, also soluble in water, and the metals of which are capable of reacting with the said soluble soap to form an insoluble soap when the finished composition or cleaner is treated with water.
These ingredients may be mixed in widely varying proportions depending on the colour and nature of the article to be cleaned and waterproofed. For example we find that for certain textile fabrics the following ingredients and proportions are suitable.
Pigment 100 parts by weight.
Soap 4 parts by weight.
Potash alum 12 parts by weight
To apply the composition it is mixed with water to a consistency of cream and is then sponged or brushed on to the fabric or material to be treated whereby the dirt is removed from the said fabric or material and the aqueous mixture penetrates the surface to a certain extent and on drying deposits a coating of insoluble soap and pigment. The coating of insoluble soap is more or less impervious to water and has the effect of waterproofing the said fabric or material to a corresponding extent. The desired colour of the treated and dried fabric or material is obtained by regulating the colour and amount of the pigment or pigments used, or by selecting a suitable metallic salt or salts or by a combination of both metods.
Dayed the 22nd day of October, 1910.

Potash alum 12 parts by weight.
To apply the composition it is mixed with water to the consistency of bream and is the sponged or brushed on to the fabric or material to be treated whereby the dirt is removed from the said fabric or material and the aqueous mixture penetrates the surface to a certain extent and on drying deposits a coating of insoluble soap and pigment or coloured matter. The coating of insoluble soap is more or less impervious to water and has the effect of waterproofing the said fabric or material to a corresponding extent. The desired colour of the treated and dried fabric or material is obtained by regulating the colour or amount of the pigment or pigments or coloured matter used, or by selecting a suitable metallic salt or salts or by a combination of both method.
Having now particularly described and ascertained the nature of our said invention and in what manner the same is performed, we declare that what we claim is :-
1. Cleaning and waterproofing textile and other fabrics and materials in one operation by applying thereto a composition of pigment, powdered soap and metallic salts or salts mixed with water, substantially as described.
