The re- 55 .laundry flakes for thirty minutes with constant agitating then rinsed and ironed, the whole operation having been repeated for more than one hundred times with no efifect upon the finish. Other similarly treated pieces were laundered and ironed in a commercial laundry without efiect upon the finish, then they were further continuously washed by the same laundry for a period of one week, then finally rinsed and ironed, after which the finish of the cloth still seemed unaflected. In this way, cottons, for example, may be washed and ironed indefinitely and will remain as stiffened and finished as they were in the beginning.
By this same method many other substances may be permanently afl'lxed to textiles. Among these bentonite is one. This substance has the quality of delustering the goods. Other substances may be similarly afiixed, for instance, precipitated chalk or commercial fire-repellant salts for fire-proofing, as well as all sorts of waxes and gums (as an emulsion in the A bath) for increasing the sheen or otherwise modifying the finish. It is also contemplated to employ many other metallic salts in the B bath along with the rare earths, for example, aluminum acetate or formate, and in this way the stearates formed by precipitation are thus rendered permanent and not removed by washing or dry cleaning as they would otherwise be.
While in practice the stearate soaps are used (bath A) because they are cheaper than others and just as satisfactory, it must be understood that the oleates, palmitates and all other similar soaps may be used.
A further modification of the method which has been found to be valuable is to use along with the soap solution in the A bath (in place of the starch, bentonite, or similar ingredients) soluble proteins which are also precipitated by the rare earths in bath B. Among the best of these proteins is the so-called alpha protein as extracted from soy beans. The same or any equally satisfactory soluble protein may be extracted from soy bean fiour by boiling said fiour with water and then filtering it. The filtrate contains the soluble proteins. These proteins used in this way will thus be precipitated along with the stearates. They provide excellent finishing and stiffening agents and may be used along with or in place of the starch.
In many cases it is possible to incorporate the soap and starch or other ingredient directly in the dye bath, and thus avoid the necessity of a second bath for the finishing. Thus it will be understood that the main purpose of, the method is to permanently afiix to fabrics such finishing substances as starch, bentonite, etc., for the stiffening, filling, delustering, fireproofing, etc., so that these treatments are made permanent and are not removed by laundering or dry cleaning. The rare earth. and other metallic soaps, as above mentioned, are used as carrying or aflixing agents for the starch, bentonite, etc.
We claim:
The method of treating textiles to affix a finish, consisting of immersing the textile in a bath of 1 to 3 percent cornstarch, 2 to 7 /2 percent stearate soap and approximately 95 percent water, wringing the textile to remove the surplus bath solution, again immersing the textile in a bath of rare earth acetates of 1 to percent concentration, wringing the textile to remove the surplus solution of the second bath, and drying the wrung textile.
