Preferably in making up the emulsion the water-insoluble material or materials are used in such proportion as to make up at'least 8 to 10% of the concentrated emulsion.
These concentrated emulsions or colloidal dispersions generally should contain more than 15% of non-aqueous material.
In preparing these'emulsions, protective colloids, such as glue, albumin, gelatine, casein, starch, gums, dimethyl-cellulose, protalbic acid, carbohydrates. sulphite waste liquors and other similar materials may be employed, preferably 100% in par-ts by weight of the water insoluble material.
In preparing certain emulsions according to the present invention it is sometimes desirable to use emulsifying agents, such as soap, sulphonated oils, aromatic sulphonic acids. and so forth, but frequently the addition or such emulsifying agents is not necessary. r
A particular feature of the present invention resides in the incorporation in' these concentrated emulsions of soluble aluminum salts,- such as aluminum acetate, aluminum formate, aluminum sulphate, alum, and so forth. It is, however, contemplated th t the aluminum salt may in part or whole be replacedby other polyvalent salts, such as copper. sulphate, lead acetate, ferric sulphate, thorium nitrate, as well as acids, such as sulphuric acid, hydrochloric acid, acetic acid and formic acid. These aluminum salts, or other polyvalent salts, or acids are preferably used in a quantity varying between 5 to 100% or more of the water insoluble colloidal material.
In preparing these emulsions or colloidal dis- -persions the aluminum salt may be conveniently added to the aqueous glue or protective colloid solution and the paraffin or other water-insoluble substance may be emulsified into or homogenized with the aluminum salt and glue solution. Parafphonic acids, and so forth. To this concentrated 7 emulsion after it has been homogenized, maythen be added aluminum salts and/or other charge rewhich usually become solid or semi-solid upon cooling, are then diluted with 20 to 50 or more parts by weight of water for each part by weight to obtain the desired treating solution or bath which is contacted with the .fabric or othertextile material.
Colloidal solutions or dispersions prepared in this manner appear to be positively charged instead of negatively charged, and they are extremely stable and will give veryimp'regnating effects substantially regardless of electrical conditions. The concentrated emulsions may be diluted merely by the addition of water without special precaution to prevent c0- agulation and the impregnating process proceeds with great expedition and with more efiicient utilization of the water-insoluble impregnating materials which aremost effectively removed from a treating bath. by the textile material or fabric. The treating solutions of the present invention are particularly are very satisfactorily treated therewith.
atmospheric Although the present invention is particularly applicable to the impregnation and especially the water proofing of woolenv materials, it is also broadly applicable to the treatment of other textile materials, to the treatment of artificial or 5 natural silk, to the treatment of paper and paper pulp, to the treatment of furs, leather and skins, and other materials.
The following are a few illustrative examples of difierent embodiments of the present invention,-to which the invention is not to be restricted.
Example 1.-300 parts of paraffin are homo genized with a solution of 100 parts of glue and 50 parts of an emulsifying agent as a. sulphonated oil or the sodium salt of an aromatic sulphonated acid in 500 parts of water. 100 parts of the emulsion so prepared are then heated to 910 to 50 0. and 15 parts of pulverized solid aluminum acetate are stirred into the emulsion. The product obtained forms a stable plastic mass when 20 cold.
This emulsion may also be prepared by first addingthe aluminum acetate to an aqueous glue solution and then emulsifying the parafiin in this aqueous glue solution in which case the emulsify- 25 ing agent may be omitted. 5 kilograms of the final emulsion may then be dissolved in from 3 to 4 times this quantity of warm water and added to a bath for treating textiles, the total volume of the bath being preferably 100'liters. 30 A woolen material may then either be milled in this liquor, or be treated on a broad washing machine, or simply be immersed in the liquor until uniformly impregnated. After centrifuging or wringing out of the woolen goods, they are 35 dried as usual. The dried materials will possess very high water-repellant properties without their feel, color or permeability being at all modifled.
Example 2.--To a solution of partsof gela- 401 tine in 700 parts of water areadded parts of solid aluminum acetate. The mixture is warmed at 60 until a uniform solution is obtained. This solution is used to emulsify a melted mixture of 125 parts of petroleum jelly and 125 parts of 45- uct. After this treatment the paper material will 50' possess excellent water-repelling properties which can not be disturbed by the addition of subversing materials. These concentrated emulsions stances increasing the stifiness of the paper, such as glue or rosin soaps, and so forth.
EzampZe 3.-In 1,000 parts of water, of gelatine are dissolved. To this warm solution 50 parts of aluminum sulphate are added and the solution is then stirred until it becomes homogeneous. In this res ltant solution then 40 parts of mineral oil and parts of stearic acid are 60 emulsified. A similar product is obtained as in Examples 1 and 2. I e
A bath containing 3 to 5% of this emulsified product may be utilized for the water proofing of chamois leather. 65
Example 4.-- bath containing 1 to 1 of the concentrated emulsions prepared according to Examples 1, 2 and 3, may be utilized to give water-repellent properties to artificial silk. The silk so treated will be completely resistant to the 70 influence of atmospheric moisture.
The following area series of examples of the composition of other emulsions which may be conand utilized as above described these emulsions being preferably pre- 75 80 parts 55-.
The present application is pared by mechanical homogenization 'of'the insoluble material with an aqueous solution of glue or gelatine and of the soluble polyvalent salt or acid.
Example 5.-20.5 kilograms of para filn, 2.5 kilograms of glue from hides, 6 kilograms oi alumi-.' num sulphate and 71 liters of water. 4
Example 6.-20.5 kilograms of neats foot oil, 5.6 kilograms of bone glue, 17.3 kilograms of aluminum sulphate and 56.5 liters of water.
Example 7.24.4 kilograms of paraflin, 6.7 kilograms of glue, 1 liter of 50% acetic acid,and 67.9 liters of water.
Example 8.-17 kilograms of paraffin, 5 kilograms of glue, 5 liters of 30% acetic acid, and 34 liters of aluminum acetate solution (25 grams ALaOa per liter) and36 liters of water.
Example 9.-19 kilograms of parafiin, 5.3 kilograms of glue, 23 kilograms of crystallized copper sulphate and 52.7 liters of water.
Example 10.--17.3 kilograms of paraflin, 4.9 kilograms of glue, 27.8 kilograms of sugar of lead, and 50 liters of water.
Example 11.12.4 kilograms of paraflln, 6.2
phate, and 78.2 liters of water.
. Example 12.23 kilograms of paraflin oil, 4.1 kilograms of glue, 41 kilograms of dimethylcellulose, 3.6 kilograms of thorium nitrate (crystallized), and 65.2 liters of .water.
All of the emulsions according to the above description have positively charged dispersed phases and when they are subjected to electrical currents the dispersed particles will tend to move to the cathode. These emulsions are all perfectly stable in the concentrated form in which they are prepared. The non-aqueous content of these concentrated emulsions average usually substantially above 15%.
These emulsions will remain unchanged even after they have been kept for days at temperatures of zero to F. At high temperatures of about 100 F. for example, these emulsions will remain completely stable, as contrasted to the usual negatively charged emulsions, which contain no aluminum salts or similar electrolytes. These latter emulsions will be destroyed if they are allowed to stand for a length of time at this temperature. It is obvious therefore that one of the advantages of the present invention resides in the fact that the emulsion produced will remain in stable condition in summer or in winter over long periods of time. This is requisite in commercial practice since these emulsions may be held in storage or in transport for days or weeks and they should not have undergone any change during this period.
Further they will not decompose even though an antiseptic is not added to preserve the organic protective colloid, since the protective charging electrolyte, as for example the aluminum salt, prevents a-destruction of the protective colloid through fermentation or other deteriorating influences. v
