Description
Patented Dec. 24, 1935 UNITED STATES PATENT OFFICE FABR Sidney G. Osborne, New York, N. Y., assignor to Hooker Electrochemical Company, New York, N. Y., a corporation of New York No Drawing. Application March 17, 1933, Serial No. 661,353
17 Claims.
More particularly, my invention relates to processes for weighting and mordanting of textiles, including silk and cotton, by impregnating with metallic salts, such as chlorides of tin, an-
timony, etc., and has for its object to render the cheaper salts more available than hitherto, to reduce the waste of these salts and to improve the quality of the product.
, Although a great number of processes for impregnating fabrics have been proposed, all of them depend upon treating the fabric with a solvent carrying in solution a metallic salt, fixing the metal by converting it to an insoluble compound and washing out the by-products. A considerable variety of metals, such as tin, lead, antimony, aluminum, barium, zirconium, etc., have been experimented with. Likewise, a number of different salts, such as the sulphate, chloride, formate, lactate, tartrate, oxalate, etc., have been tried or proposed. However, ninety per cent of all silk weighting is carried out today by the use of-tin tetrachloride. The solvent used has invariably been water, and hydrolysis has been the means depended upon for fixing the metal. Hydrolysis converts the salt into the oxide, the original acid radical reappearing as free acid, which must be neutralized and removed by washing. A further treatment with disodium phosphate and sodium silicate serves to convert the metal into so complex insoluble salts that have been found to impart desirable characteristics to textile fabrics.
Since the process above described depends upon hydrolysis, it will be obvious that an inhibitor of hydrolysis must be employed when making up the water solution. For this purpose it is common practice to acidify with the acid of the salt used. Thus if the salt is a chloride, it is usual to acidify with muriatic acid. Common salt is also sometimes added. These materials may have a deleterious effect upon the fabric. Before hydrolysis can take place, the inhibitor must be removed. This is commonly accomplished by washing; but it is obviously impossible to Wash out the inhibitor without at the same time carrying away some of the metallic salt. In practice, it is quite common to lose thirty per cent of the metal in this way.
Tin chloride is a relatively expensive material. Other cheaper chlorides are available, such as antimony chloride, but this salt hydrolizes so readily that the inhibitor must be in greater concentration and the possible injury to the fabric may be proportionately increased.
To obviate these difficulties, I substitute for water a non-aqueous or organic solvent, prefer ably volatile. Such solvents have greater penetrating power, especially when there is a water repellent animal or vegetable wax or oil present in the fibre, as is usually the case. They do not injure the fabric; neither do they react with the 5 salt to cause hydrolysis. Consequently, no inhibitor is necessary and the injury to the fabric from acid inhibitors is avoided. Moreover, since there is no inhibitor to be washed out, the waste of metallic salt in this step is eliminated. In 10 my preferred process, it is only necessary, after impregnation, to evaporate ofi the solvent and expose the fabric to the action of water, which may be vapor or steam. This of course carries nothing out of the fabric. The acid formed by 5 the hydrolysis may then be washed out in the usual way, the metal at this stage having been converted into an insoluble compound. Before impregnating-in accordance with my process, the
fabric may be soaked in an alkaline solution and 20 dried, but I prefer to use an alkaline vapor, thus neutralizing the acid as formed. For this purpose, the vapor from an alkaline solution, such as a solution of ammonia or amines may be used;
or gaseous ammonia may be mingled with the 25 water vapor. In the latter case, the ammonium chloride formed is easily removed by washing. This process may be repeated until the desired weighting'eflect has'been attained. The treatment with disodium phosphate and sodium silicate may then be proceeded with if desired.
My process therefore permits the use of the relatively cheap antimony chloride (which costs less than half as much as tin chloride) without any waste in the hydrolysis step or exposure of the 35 fabric to acid either before or during hydrolysis, and thus results in a stronger, better and cheaper product.
The organic solvent used in carrying out my rocess may be any of the well known organic 40 solvents, such as acetone, methanol, carbon tetrachloride or a hydrocarbon, such as benzol, toluol or gasoline. Chlorinated hydrocarbons are for some purposes advantageous over non-chlorinat- 45 ed hydrocarbons. In general, chlorination of hydrocarbons reduces fire hazard and toxicity; moreover, the solvent properties may be distinctly improved for specific purposes, such as for certain waxes. Examples of chlorinated hydrocarbons 50 having superior solvent properties are monochlor benzol, trichlor ethylene, ethylene dichloride, etc. Carbon tetrachloride is also an example of a chlorinated hydrocarbon. It is to be understoodthat chlorinated hydrocarbons are considered as 55 hydrocarbons within the meaning of this specification and the subjoined claims.
It will be obvious that my process is equally applicable to weighting of silk and mordanting of cotton, the advantages being substantially the same in either case.
The essence of my invention resides in the avoidance of a solvent that reacts with the salt to cause hydrolysis. Any non-aqueous solvent fulfills this condition. I do not wish to be limited, therefore, to one metal or to any particular metal, salt or solvent, so long as the solvent fulfills the condition just enunciated. For example, a solvent that, of itself, reacted with the salt or salts but only under easily controllable conditions, such as exposure to the air, would likewise fall within the scope of my invention.
Neither do I wish to be limited to hydrolysis as the means of fixing the metal in the fabric, since any method of causing conversion to the oxide or any other insoluble compound will produce the desired result. For example, when ther'e is no inhibitor present, exposure to heat, air or a non-aqueous alkali may accomplish the pur-v hydrolysis to a non-water-soluble compound of the metal.
