Definitions

• the present invention relates to the treatment of textiles and, more particularly, to the dyeing of textiles by the use of dilute solutions of alkalimetal hexametaphosphates.
• the textile fibers employed are or animal or vegetable origin or of artificial preparation.
• the first are wool and silk; oi the second, cotton and linen; of the third, rayon or other forms or artificial silk made by 10 various processes.
• - Textile fibers may be dyed between any of the steps used in the manufacture of the finished fabnic, namely, they maybe dyed in the form or stock, either raw or previously scoured, in the 15 form of partially or fully combed but untwisted fiber, known as sliver or slubbing, in the form of twisted thread or yarn, or finally in the completely woven piece.
• the object to be attained is the dyeing oi the material to an even shade and of the color desired.
• the woven piece is composed of 85 threads or different classes of fibers which have diflerent aflinities for certain dyes, it is sometimes wished to dye the whole equally and evenly, and at others to choose such dyes or dyeing methods as will color the threads of one composition a & certain color and leave the threads of the other material a difierent color or in their original white condition.
• specific colored designs are given to woven cloth by printing locally there- 35 on certain pigments, dyes or the component parts of dyes and then setting the pigments or develop-v ing the dyes of which a certain essential part or parts were locally applied by subjecting the whole piece of cloth to a uniform treatment.
• Penetration or the evenness thereof may be hindered by fats, waxes, oils, or metallic soaps existing either naturally in the fiber or imposed thereon by some process prior to the dyeing operation.
• dye kettle or'the piping thereto may, in many cases, have most serious results in dulling' or otherwise modifying the color produced by the dye.
• certain metallic salts are deliberately added to the dye bath or else precipitated on the material to be dyed, either prior to the dyeing thereof or subsequently thereto, for the purpose of firmly fixing the dye to the fiber or for changing the color produced otherwise by the dye alone,to a more desired one.
• the dyeing vessel had adjacent thereto a smaller vessel open at the top and the two were so interconnected by piping that the dye liquor in the smaller vessel could be forced by a mechanically driven pump, installed in the pipe line leading from the smaller vessel, into the top of the dyeing vessel, through the material to be dyed and re turned from the bottom of the dyeing vessel to the smaller auxiliary container.
• the dye liquor could thus be continuously clr culated through the material to be dyed.
• a small pipe line conveying steam entered the delivery pipe and enabled the circulating dye liquor to be gradually raised to the boiling point.
• the dyeing machine having been prepared as above, the dyeing was started at an approximate temperature of 100 to 110 F. and brought up to the, boiling point during a period or thirty minutes.
• the dye liquor was boiled for twenty minutes.
• fiIteen pounds of sodium sulphate was added and the boiling continued .for twenty minutes more.
• thirty pounds more sodium sulphate was added and the boiling continued for another twenty minutes.
• sixty pounds more sodium sulphate was added and the boiling continued for another twuty minutes.
• the dye bath containing the material to be dyed was brought to the boil, 'boiled three- 70 quarters 01' an hour, 10 pounds formic acid added. boiled one-halt hour, 4% pounds sodium dichromate added half hour.
• the dye Diamond blue black R. B. N., dyes red but the subsequent treatment with dichromate turnsit to a blue, thus intensifying the black shade or the dye that is present in the largest portion.
• any failure of completeness of the chroming would allow the orisinal red color oi. the blue black to remain and give a reddish cast to portions of the dyed material.
• the material dyed without the use oi" sodium hexametaphosphate not only dyed unevenly, but chromed unevenly as well, whereas the slubbing dyed with the addition oi the metaphosphate not only dyed evenly, but chromed more thoroughlyand evenly and showed no traces of spots oi reddish'hue.
• phates may be used, such as the potassium and ammonium salts. These'alkali-metal hexametaamines I 3 by' the elimination of the sludge in one of the examples above.
• the step which which consists in subjecting the textiles' 1o to a dyeing bath containing an alkali metal hexametaphosphate.
• the-step which consists in subjecting the textiles to a dyeing bath containing sodium hexameta- 15 phosphate.
