Description

- methyl violet. This cotton so dyed is of a AUGUST LEN'DLE, 0F FOREST HILLS, NEW YORK, ASSIGNOR TU KUTTROFIE PICK- HARDT & 00., INC., 011 NEW YORK, N. EL, A. CORPORATION OF NEW-YORIL inn'rnon on nrnrne.

2" 0 all whom it may concern:
Be it known that l, AUGUs'r LENDLE, a citizen of the United States, residing at Forest Hills, county of Queens, and State of New York, have invented new and useful Improvements in Methods of Dyeing, of which the following is a specification.
My invention comprises a new and, improved method of dyeing whereby dyeings of basic colors on cotton, jute, wool, silk or other textiles and fibers, on Which the dyes are of a relatively fugitive and unstable character, are rendered more permanent and fast to light.
Itis well known that when the above named articles are dyed with basic colors in the ordinary method of dyeing the colors are not permanent and are affected by light. By means of my improved method this objection is eliminated. After the goods are treated with my method the colors are relatively fast and permanent.
I have discovered that an after-treatment of such dyeings with acids (such as phosphoric or silicic) or their salts, containing a difficulty-fusible metal (such as tungsten or molybdenum) renders said dyeings relatively fast to sunlight and permanent.
.The following are examples of suitable procedure but my invention is not confined to these examples.-
.Eccamp Z0 1.
Take 100 lbs. cotton yarn mordanted in the usual and'we'll-known manner with tannic acid and antimony salt, and dyed in the well-known fashion with say one-half lb.
beautiful purple hue, but of a very fugitive and transitory nature. It is then subjected to an after-treatment by putting it into a solution of five lbs. sodium phospho tungstate or of five lbs. sodium phospho molybudate, in 300 gallons of water. 1 lhis aftertreatment can either be done at ordinary Specification of Letters Patent. Patented Apr. 26, 12921.

temperature or preferably at a raised temperatnre.
Ewample h'.
1,000 lbs, unbleached sulfite 'cellulose are brought in contact with 10 lbs. malachite green dissolved in water, preferably in an apparatus commonly known as a beater. After a short time the coloring matter is absorbed by the cellulose, the application of .heat or the use of mordants being unnecessary. The resulting green colored cellulose is then treated with a solution of say, 80 lbs.
sodium phospho tungstate, preferably at raised temperature, resulting in'a permanent green shade.
Instead of methyl violet and malachite green, other basic colors can be used, such as methylene blue, Victoria blue, auramin, etc. Instead of the salts, the complex acids themselves may be used.
I claim:
1. The method of dyeing consistingof dyeing fabric with a basic color, and subse with a complex acid containing phosphorus and tungsten.
In testimony whereof I have hereunto set my hand 1n the presence of two subscribing witnesses. V
AUGUST LENDLE.
