Description

I FIP8389 UHHUN ur HZAHLLD GA l'iUfLli-S,
CHARLES MOADAM AND VICTOR O. OLSEN, OF CHICAGO, ILLINOIS, ASSIGNORS TO CHARLES MCADAM 00., OF CHICAGO, ILLINOIS, A CORPORATION OF DELAWARE.
No Drawing.
T 0 all whom it may concern:
Be it known that we, CHARLES MGADAM and VICTOR O. OLSEN, citizens of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Bleaching and Cleaning Compositions, of which the followin is a specification, reference being had to t e accompanying drawings, and to the reference characters marked thereon,
which form a part of this specification.
This invention relates to new and useful improvements in bleaching and cleaning composition or souls and more particularly to a sour composed of inorganic salts so compounded as not to deteriorate upon storing; which will have practically no deleterious effect on fabric upon which it may be used, and which upon being combined with water, will be immediately ready for use.
It is known, for example, that sodium silico fluoride when mixed dry with sodium bisulphate (nitre cake or salt cake) produces no chemical reaction. We have discovered that when these two chemicals are mixed with or dissolved in water, the free sulphuric acid in the sodium bisulphate acts upon the sodium silico fluoride to liberate fluorine. Fluorine in water forms hydrofluoric acid, which is a good bleaching agent.
Our invention, therefore, consists in preparing a composition suitable for use in laundries and other places as a bleacher or sour to take the place of oxalic acid and acetic acids heretofore used in laundry work to neutralize the alkalies.
Our blealcher or sour is desi ned to ac.-
complish the removal of rust, fruit and other 'stains in the fabrics being cleaned, and at the same time to reduce to a mimimum the deleterious effects upon the fabric which scouring agents, per se, tend to produce.
A composition suitable for this purpose ZBLEAGHING AND CLEANING COMPOSITION.
Application filed November 4', 1921. Serial No. 512,867
may be prepared by intimately mixing.
ninety (90) parts of sodium silico fluoride (Na SiF by weight, with ten (10) parts of sodium bisulphate (NaHSO,,) by weight. I may substitute, for the sodium silico fluoride, the same amount of potassium silico fluoride (K SiF or ammonium silico fluoride (NH SiF This composition may be dissolved in water, either hot or cold, and then added to the water in the tub in which the garments are immersed. In using the composition for laundry purposes, for example, the garments are first washed in the usual manner with soap, the soap suds are rinsed therefrom and then clear water added, either hot or cold. There will still be some alkali in the garments. The clothes are then ready for souring. We add bursouring material, dry or diluted as stated, and raise the temperature of the water by any suitable means to practically the boiling point, for a short period, usually .about ten minutes; then Search Room drain off-the water, and complete the rins- 7 ing, blueing, etc.,..in the usual manner.
It will be found that stains'have been removed, and the clothes; are thoroughly bleached, without any deleterious effect upon the structure of the fabrics.
lVe claim as our invention: A bleachin composition or sour containing sodium iisulphate and sodium silico fluoride.
In testimony, that we claim the foregoing. as our invention we affix our slgnatures 1n Witnesses:
