Description
UNITED STATES PATENT FFIcE...
J OI'IN THOMAS REID AND HENRY TI-IORP, OF PENDLETON, ENGLAND.
PROCESS OF DYEING KHAKI.
$P ECIFIGATION forming part of Letters Patent No. 631,906, dated August 29, 1899.
Application filed February 2 5 1 8 9 9.
To all whom it may concern:
Be it known that we, J OHN THOMAS REID and HENRY THORP, subjects of the Queen of Great Britain, and residents of Pendleton near Manchester, in the county of Lancaster, England, have invented certain new and useful Improvements in Dyeing Textile Fibers, Yarns, and Fabrics, of which the following is a specification.
The invention is an improvement on the subject-matter of United States Patent No. 612,274, granted to us October 11, 1898, and relates to improvements in dyeing vegetable fibers, yarns, and fabrics, hereinafter for convenience-of description referred to as fibrous materials, the object of our invention being to obtain certain fast and permanent colors known'as khaki shades.
In our former patent We described a process consisting in first scouring the fibrous materials to free them from all impurities, then drying, and when dry running them through a bath of olein-oil and water. WVe have since found that this bath is not necessary and that the process can be simplified and cheapened by'omitting this step.
In carrying our present invention into effect we first scour the fibrous materials to free them from all impurities, then dry, and afterward impregnate them with the following dye liquor: twenty gallons of a solution of acetate of chromium, (20 Twaddell,) twenty gallons of a solution of acetate of iron, (12 Twaddell,) and eight ounces of alizarin-blue S dissolved in four gallons of a solution of bisulfite of soda or potash, (54: Twaddell.) Vhen thoroughly impregnated with $erial1l0- 706,863. (No specimens.)
the above liquor, we mangle the fibrous materials and then dry them. We then steam the fibrous materials for about an hour at, say, a steam-pressure of four pounds to the square inch, and subsequently develop and fix the color by passing the fibrous materials through an alkaline bath composed, say, of sixteen gallons of water, eight pounds of common soda, and three gallons of lime-water. We then by preference soap the fibrous materials and finally wash and dry them. For full or dark'shades we may repeat the above process as often as required and may Vary the proportions for different shades as required.
In place of the alizarin-blue S we might employ ordinary alizarin-blue, gallein, cerulein, or like product of anthracene, and in place of the acetates we might employ any other suitable salts of chromium and iron.
What we claim is The process of dyeing vegetable fibrous materials certain fast and permanent colors known as khaki shades which process consists in impregnating the fibrous materials with a mixed solution of alizarin-blue S, chromium and iron salts, then drying, steaming and developing the color by treatment with an alkali substantially as herein set forth.
In witness whereof we have hereunto set our hands in presence of two witnesses.
JOHN THOMAS REID. HENRY THORP.
