Definitions
- This invention relates to compositions for and methods of finishing textile materials, and more particularly to methods of making textile materials water-repellent by impregnating them with a composition containing organic esters of phosphoric acid and organic amido-compounds.
- textile malerials can be rendered water-repellent by impregnating them with aqueous solutions containing acid esters formed by esterifying phosphoric acid with high-molecular alcohols and phenols.
- Acid esters of the above type which may advantageously be employed to make textiles water-repellent in accordance with my invention include mono-esters having the general structural formula Rt-O wherein R is a hydrocarbon radical containing at least 6 carbon atoms selected from the group consisting of high-molecular alkyl, cycloalkyl, alkylcycloalkyl, and
- alkylaryl radicals and di-esters having the general structural formula P-OH wherein R is a hydrocarbon radical as defined above and R is also a hydrocarbon radical containing at least 6 carbon atoms, selected from the group consisting of alkyl, cycloalkyl, alkylcycloalkyl, and alkylaryl radicals.
- R and R may be identical radicals or radicals of ditferent structure; in other Words, the di-esters can'be simple or mixed di-esters.
- R and R may also carry substituents or may be interrupted by oxygen, sulfur or nitrogen atoms or by heteroatom groups derived therefrom.
- phosphoric acid esters which can be used to impart Water-repellent properties to textile materials in accordance with my invention are the following:
- I first immerse the textile material in an aqueous solution containing from 1 to 20 gm./liter of any one of the above monoor di-esters of phosphoric acid. Thereafter, I pass the treated material through a wringer to remove excess amounts of solution, and then dry and heat the wet impregnated material at a temperature in excess of 90 C. to remove the water while leaving the phosphoric acid ester compound afiixed to the textile fibers.
- the water-repellent effect created on textiles by the above procedure can be further improved by treating the dried fabric with dilute solutions of salts of bivalent, trivalent or tetravalent metals, particularly of aluminum salts, or by simply rinsing the dried cloth in hard water.
- Amido-compounds of this type are, for example, the following: Urea, thiourea, alkylated urea, methylenediurea, methane, guanidine, alkylated guanidine, cyanamide, dicyandiamide, dicyandiamidine, as Well as cyclic compounds such as methyldiaminotriazine, triaminotriazine (melamine), melam, melem, mellone, ammeline and the like.
- I first prepare an aqueous solution containing from 1 to 20 gm./liter of the acid phosphoric acid ester, and if desired also, from 1 to 20 gin/liter of the amino-compound.- I then pass the textile material into this solution, subsequently run the material through a wringer to remove ex-. cess solution, and finally dry the wet fabric at a temperature above 90 C.
- Both the treatment with the solutions of acid phosphoric acid esters alone and with the mixed solution of the phosphoric acid ester and the amide-compound can be applied to textile materials in the form of threads, strips, and fabrics.
- it may be applied to cotton, regenerated cellulose, rayon, jute, linen, wool, silk, as well as 100%-syntheti-c fibers.
- Example I Cotton poplin fabric was wetted with a solution containing 3 gm./liter of the monocetyl ester of phosphoric acid. The wetted fabric was then removed from the so lution and passed through a wringer where all of the solution was removed which was in excess of the amount required to bring the weight of the wet cloth up to 3 above the weight of the dry cloth. Thereafter, the wet cloth was dried at 90 C. The finished dry cloth was found to be adequately water-repellent.
- Example Il Unbleached cotton cloth was immersed in a solution containing 3 gm./liter of the monocetyl ester of phosphoric acid and 0.5 gm./liter of ammonia. The "treated fabric was then removed from the solution, passed through a wringer to remove excess solution as in Example I, and dried at 100 C. Subsequently, the dry fabric was rinsed for one hour in hard water, and again dried. Unbleached cotton cloth treated in this manner was found to be satisfactorily water-repellent.
- Example III Cotton poplin cloth was passed into a solution contain ing 15 gm./liter of the monododecylester of phosphoric acid and 7.5 gm./liter of cyanamide. The treated fabric was then removed from the solution and passed through a wringer where all of the solution was removed in excess of the amount required to bring the weight of the wet cloth up to 100% above the weight of the dry cloth. Thereafter, the wet cloth was dried at 60 C. and then exposed to a temperature of 120 C. for minutes. The treated cloth exhibits good water-repellent properties which can be improved by washing the treated cloth under mild conditions at 45 C. The water-repellent effect also survived repeated laundering of the treated fabric.

Description
United States Patent COMPOSITIONS FOR AND METHODS OF FINISHING TEXTILE MATERIALS Hans Wedell, Dusseldorf-Hoithausen, Germany, assignor to Bijhme Fettchemie G. in. b. H., Dusseldorf, Germany, a corporation of Germany v No Drawing. Application November 15, 1954 Serial No. 469,053
This invention relates to compositions for and methods of finishing textile materials, and more particularly to methods of making textile materials water-repellent by impregnating them with a composition containing organic esters of phosphoric acid and organic amido-compounds.
I have found that textile malerials can be rendered water-repellent by impregnating them with aqueous solutions containing acid esters formed by esterifying phosphoric acid with high-molecular alcohols and phenols.
Acid esters of the above type which may advantageously be employed to make textiles water-repellent in accordance with my invention include mono-esters having the general structural formula Rt-O wherein R is a hydrocarbon radical containing at least 6 carbon atoms selected from the group consisting of high-molecular alkyl, cycloalkyl, alkylcycloalkyl, and
alkylaryl radicals, and di-esters having the general structural formula P-OH wherein R is a hydrocarbon radical as defined above and R is also a hydrocarbon radical containing at least 6 carbon atoms, selected from the group consisting of alkyl, cycloalkyl, alkylcycloalkyl, and alkylaryl radicals. In the di-ester formula, R and R may be identical radicals or radicals of ditferent structure; in other Words, the di-esters can'be simple or mixed di-esters. R and R may also carry substituents or may be interrupted by oxygen, sulfur or nitrogen atoms or by heteroatom groups derived therefrom.
Specific illustrative examples of phosphoric acid esters which can be used to impart Water-repellent properties to textile materials in accordance with my invention are the following:
Phosphoric acid dihexyl ester Phosphoric acid dioctyl ester Phosphoric acid didodecyl ester Phosphoric acid dioleyl ester Phosphoric acid dimontanyl ester Phosphoric acid dimethylcyclohexyl ester Phosphoric aci-d dinaphthenyl ester Phosphoric acid diabietyl ester Phosphoric acid dibenzyl ester Phosphoric acid dimenaphthyl ester water-soluble or at least dispersible in water; the esters wherein R and/ or R contain from 6 to 18 carbon atoms are readily water-soluble, while those wherein R and/ or R contain more than 18 carbon atoms are relatively insoluble, but may be dispersed in water with the aid of low-molecular alcohols such as ethylalcohol and isopropylalcoho-l, ketones such as 2-butanone, ethers such as glycerin monoalkyl ethers, or etheralcohols such as tetrahydrofurfurylalcohol, acting as solubilizing agents.
In a few special cases it is possible to partially neutralize the particular acid phosphoric acid esters with volatile inorganic alkaline substances such as ammonia, or with organic alkaline compounds such as alkylamines, alkylpiperidines and the like.
In practicing my invention, I first immerse the textile material in an aqueous solution containing from 1 to 20 gm./liter of any one of the above monoor di-esters of phosphoric acid. Thereafter, I pass the treated material through a wringer to remove excess amounts of solution, and then dry and heat the wet impregnated material at a temperature in excess of 90 C. to remove the water while leaving the phosphoric acid ester compound afiixed to the textile fibers.
The water-repellent effect created on textiles by the above procedure can be further improved by treating the dried fabric with dilute solutions of salts of bivalent, trivalent or tetravalent metals, particularly of aluminum salts, or by simply rinsing the dried cloth in hard water.
I have further found that the process of rendering textile materials Water-repellent, in accordance with my invention, as above set forth, can be materially improved by impregnating such textile materials with an aqueous solution containing not only the above-described acid esters of phosphoric acid, but also amide-compounds which contain at least one amino-group bonded to a CO--, CS, C(NH), or CN-group, said amino group containing at least one replaceable hydrogen atom.
Amido-compounds of this type are, for example, the following: Urea, thiourea, alkylated urea, methylenediurea, methane, guanidine, alkylated guanidine, cyanamide, dicyandiamide, dicyandiamidine, as Well as cyclic compounds such as methyldiaminotriazine, triaminotriazine (melamine), melam, melem, mellone, ammeline and the like.
In practicing the improved method of my invention, I first prepare an aqueous solution containing from 1 to 20 gm./liter of the acid phosphoric acid ester, and if desired also, from 1 to 20 gin/liter of the amino-compound.- I then pass the textile material into this solution, subsequently run the material through a wringer to remove ex-. cess solution, and finally dry the wet fabric at a temperature above 90 C.
Both the treatment with the solutions of acid phosphoric acid esters alone and with the mixed solution of the phosphoric acid ester and the amide-compound can be applied to textile materials in the form of threads, strips, and fabrics. For example, it may be applied to cotton, regenerated cellulose, rayon, jute, linen, wool, silk, as well as 100%-syntheti-c fibers.
The following examples will further illustrate my invention and enable others skilled in the art to understand as well as di-alkylphen'yl esters wherein the alkyl radimy invention more completely. However, it is understood that there is no intention on my part to limit the invention to these particular examples.
Example I Cotton poplin fabric was wetted with a solution containing 3 gm./liter of the monocetyl ester of phosphoric acid. The wetted fabric was then removed from the so lution and passed through a wringer where all of the solution was removed which was in excess of the amount required to bring the weight of the wet cloth up to 3 above the weight of the dry cloth. Thereafter, the wet cloth was dried at 90 C. The finished dry cloth was found to be adequately water-repellent.
Example Il Unbleached cotton cloth was immersed in a solution containing 3 gm./liter of the monocetyl ester of phosphoric acid and 0.5 gm./liter of ammonia. The "treated fabric was then removed from the solution, passed through a wringer to remove excess solution as in Example I, and dried at 100 C. Subsequently, the dry fabric was rinsed for one hour in hard water, and again dried. Unbleached cotton cloth treated in this manner was found to be satisfactorily water-repellent.
Example III Cotton poplin cloth was passed into a solution contain ing 15 gm./liter of the monododecylester of phosphoric acid and 7.5 gm./liter of cyanamide. The treated fabric was then removed from the solution and passed through a wringer where all of the solution was removed in excess of the amount required to bring the weight of the wet cloth up to 100% above the weight of the dry cloth. Thereafter, the wet cloth was dried at 60 C. and then exposed to a temperature of 120 C. for minutes. The treated cloth exhibits good water-repellent properties which can be improved by washing the treated cloth under mild conditions at 45 C. The water-repellent effect also survived repeated laundering of the treated fabric.
Example I'V Unbleached cotton cloth was inserted into a solution containing 2 gm./liter of a dialkyl ester of phosphoric acid, wherein the alkyl radicals contained from 16 to 18 carbon atoms, and 1 gm./ liter of cyanamide. The wetted fabric was then removed from the solution and wrung out and dried as described in Example III. The result was a hydrophobic textile fabric which retained its waterrepellent properties even after repeated laundering.
Example V Cotton fabric was passed into a solution which contained 10 gm./liter of a monoalkylester of phosphoric acid, wherein the alkyl radical contained from 16 to 18 carbon atoms, 3 gm./liter of melanine and 50 gm./liter isopropanol. The wetted fabric was then removed from the solution and wrung out and dried as in Example III. The result was a hydrophobic fabric which retained its water-repellent properties even after repeated laundering.
Example VI Example VII Wool cloth was passed at 60 C. into a dispersion con taining 10 gm./liter of a mixture of monoand di-octadecylester of phosphoric acid, gin/liter of cyanamide, and 100 gm./ liter of isopropanol. The treated cloth was then removed from the dispersion, passed through a .wringer to remove excess solution and dried at 105 C.
The finished dry cloth was found to be satisfactorily water-repellent. The water-repellent effect survived repeated laundering.
In certain cases it may be that the acid esters of phosphoric acid, used according to the invention, are not sufficiently water-soluble. Then it is possible to use them in aqueous dispersion. For improving the solubility it 4 V is useful to add small amounts of volatile inorganic or organic bases as described, which are removed during the drying process of the impregnated cloth. Under certain conditions it may be advantageous to use the acid esters in organic solvents such as halogen hydrocarbons or benzene.
