'2-Claims, No Drawings ANTISTATIC FINISHING OF SURFACES This invention relates to the antistatic finishing of surfaces of shaped articles, especially textiles, which tend to acquire an electrostatic charge, using quaternary ammonium compounds which contain 2 to 4 hydroxyethyl groups per ammonium group.
It is known that many articles consisting of macromolecular materials tend to build up an objectionable electrostatic charge during processing or in use. This tendency is particularly common with articles of synthetic macromolecular materials; however, it is not restricted to these but also occurs with fibers of cellulose esters and even fibers of cellulose, regenerated cellulose, silk, wool and other vegetable and animal products, when the moisture content of these fibers which is primarily determined by the relative atmospheric humidity falls below a certain limit. This limit differs from one type of fiber to another.
Numerous chemical compounds have already been proposed as antistatic agents. The conventional antistaticagents are mostly longchain alkyl oraralkyl compounds of the non-ionic, anionic or cationic type. Amongst these, the cationic fatty alkyl compounds of nitrogen or phosphorus, in the form of their tertiary or quaternary salts, are preferred because by virtue of their substantivity and their orientability on the surface of the fiber they produce very good antistatic effects. The orientation of the molecules of these surfaceactive positively charged compounds is attributable to their chemical structure which is characterized by a long hydrophobic alkyl radical of 8 to carbon atoms and a hydrophilic salt-forming group. A cycloaliphatic or aromatic radical can take the place of the longchain alkyl radical, but, evidently for steric reasons, these products are less effective antistatic agents than the aliphatic compounds.
The disadvantage of these compounds is that they are strongly cationic, hence react both with anionic surfactants and with anionic dyes to form sparingly soluble salts, and therefore cannot be used conjointly with such surfactants or dyes.
Compounds which act as antistatic agents and, in spite of their pronounced positive charge, do not react as cationic compounds have been disclosed in the literature. These are substituted urea derivatives which, however, suffer from the disadvantage when used on textiles that the substrate finished with them can develop an unpleasant fishy odor on storage under adverse conditions. I
It is an object of the present invention to provide a process for antistatic finishing, especially of textiles, which is at least as good as the conventional processes in respect of antistatic activity but does not suffer from the disadvantages described.
We have found a process for antistatic finishing of surfaces of shaped articleswhich tend to build up an electrostatic charge, by coating with ammonium salts, wherein the coating agents used are ammonium salts of the formula Q-I ((:H. cH, oH)z x6 where X is a monovalent organic or inorganic anion or the n-th part of an n-valent anion of a water-soluble acid, (i.e., one equivalent of an anion of a water-soluble acid) R and Q independently of one another are each hydroxyalkyl of 2 or 3 carbon atoms, alkyl of l to 6 carbon atoms or benzyl and Q can also be the radical in which A is alkylene of 2 to 6 carbon atoms. Compounds of the said formula in which R is hydroxyethyl and Q is methyl or ethyl are preferred.
The compounds can be obtained conventionally-by reaction of appropriately substituted diethanolamines or of triethanolamine with alkylating, hydroxyalkylating or benzylating agents, such as dialkyl sulfates, alkyl 7 halides or alkyl dihalides, toluenesulfonic acid alkyl esters, benzyl chloride or ethylene oxide or propylene oxide together with acids, in equimolar ratios. The quaternization reactions take place at temperatures of 20 to C though with some sluggish quaternizing agents temperatures of up to C are required. Solvents can be used for example for the purposeof cooling the mixture through boiling of the solvent.
As the anion X it is possible to use more or less any watersoluble organic or inorganic acid radicals. For economic reasons, the anions of industrially available acids, for example of sulfuric acid, hydrochloric acid, hydrobromic acid, toluenesulfonic acid and methylsulfuric acid are preferred.
Compounds with fewer than two 2-hydroxyethyl groups on the quaternary nitrogen are not sufficiently active antistatically.
The compounds, and their manufacture, are not claimed herein.
In contrast to the quaternary ammonium compounds conventionally used for this purpose, the compounds of the formula shown exhibit an antistatic action, even at low relative atmospheric humidities, to a hitherto unknown degree. They are therefore particularly suitable for the antistatic finishing of fibrous textile materials of all kinds, for example fibers, filaments, tops, card slivers, yarns, non-woven fabrics, felts, woven fabrics and knitted fabrics, consisting of synthetic high molecular materials, such as'linear polyesters, polyamides, acrylonitrile polymers, p'olyolefins and polyvinyl compounds, or consisting of natural high molecular weight materials or their derivatives, such as cellulose, regenerated cellulose, cellulose esters, silk, wool and other vegetable and animal materials.
The antistatic effect of the compounds persists for a prolonged period even at high temperatures; textile materials finished with these compounds do not yellow, because of the high heat stability of the compounds. In spite of their pronounced positive charge the compounds do not behave as cationic compounds, that is to say they react neither with anionic surfactant nor with anionic dyes to form precipitates, so that they are universally applicable without the hazard of the difficulties which arise, when using the conventional cationic antistatic compounds, during subsequent finishing processes such as dyeing, wash-and wear finishing and hydrophobic treatments. Their particular advantage is that even on storing the finished textiles under adverse conditions a fishy odor does not develop.
In addition, these antistatic agents have further advantages in use over the fatty alkyl-ammonium salts.
They give completely clear colorless solutions in water even at room temperature. The viscosity of these solutions is low even at concentrations of 50 to 80 per cent by weight of the compounds, so that they can be 4 nation products of natural fats of animal or vegetable origin, oxyalkylation products of fatty acids, sulfonate salts of alkylated aromatics, sulfuric acid ester salts of fatty alcohols and of partial fatty acid esters of polyhydsprayed at high concentrations.
