METHOD OF DYEING HANKS.
Application filed September 2, 1925. Serial No 54,088.
This invention relates to a method of dyeing llilnkSrOf yarn by means of developing dyes, vat dyes. sulphur dyes and so on.
In the vat-dyeing of hanks of yarn it is "ery difficult, as is well known, to obtain uniformity in the colouring. One reason for this is the very non-uniform penetration of the hanks in the vats, particularly in the case of solid yarns. This lack of uniform distribution of liquor within the mass of yarn is accentuated upon wringing, so that in subsequent development or oxidation, the yarn is found. to be thoroughly non-uniform.
The principal objectof this invention is to provide a method of dyeing which obviates the known disadvantages.
A further object is to provide a dye-spraying method involving the spraying of the dye on to the hanks simultaneously from opposite sides. whereby a thoroughly uniform penetration is achieved.
It has been proposed to spray wetting agents on to fabrics in order to secure a more uniform distribution than is possible by dipping. However, the mere spraying of dye liquors on to hanks suspended freely over rollers and moving with the latter would not of itself achieve a uniform colouring.
The invention provides for the employment of opposed jets or sprays of liquor so that the hank is struck simultaneously from opposite sides and under such pressure that not only is superficial penetration assured but the matting together of the separate yarns in the wet hank is broken down or destroyed so that a loosening of the hank is achieved. Thus. whereas there is a natural tendency for matting to take place owing to the capillary attraction between the wet yarns, this matting is avoided and the hank' is loosened by the force of the opposed jets which are directed to the same point inside and outside of the loosely hanging hank. Spraying the hank upon portions which lie upon the roller does not achieve the object aforesaid as the hank cannot alter its cross section at this resting place and the separate yarns cannot deform or move.
The annexed drawing is a diagrammatic illustration of one convenient and practical mode of carrying out the method.
The hanks are suspended from a plurality of revolving rollers a and beneath the level of the latter there is a series of spray tubes 6 b. Thespray tubes 6 are disposed immediately beneath respective rollers a so that they lie within the loops of the suspended hanks, whereas the spray tubes 1) are disposed intermediately so that they lie between and outside of the hanks. The spray nozzles or perforations of the tubes 6 b are disposed by any practical mechanical means, and this 1s of particular importance when considering developing dyes. No longer is it necessary to remove the goods from the rollers for the oxidation. for after uniform impregnation the hanks are allowed to remain hanging from the rollers which continue to revolve until the dyeing is completed by development or oxidation. Washing can then be effected immediately and with the same a'pparatus.
This invention effects a considerable saving in dye, labour, steam and water. For example, the quantity of dye liquor is reduced to one fifth. There is a saving of about 50% of the dye required and a saving of about of the steam required for heating the liquor. Finally, the saving of washing water is about four fifths of that heretofore required. As .compared with hand dyeing by the development process a saving of five sixths of the time is effected.
The invention is of particular importance forthe uniform dyein ,of bulky material such as Sirius silk, arti cial horse hair, and viscous silk. Moreover, hanks of very fine cotton yarn can be uniformly dyed, whereas with known methods this is not possible on account of the capillary action causing the fine yarns in the wet condition to mat together and form solid hanks which are difficult to penetrate with uniformity.
I claim v 1. Method of dyein'r hanks of yarn comprising suspension oF the hanks from rotating rollers and spraying hanging parts of the hanks by opposed jets substantially as set forth.
2. Method of dyeing hanks of yarn comprising suspension of the hanks from rotating rollers and spraying hangingparts of the hanks by opposed jets, the force of the jets being calculated so as to be effective for loosening the texture of the sprayed portions of the hanks substantially as set forth.
3. Method of dyeing a hank of yarn comprising suspension of the hank from a rotary roller, and the simultaneous employment of opposed spray jets within and without the hank substantially as set forth.
4. Method of dyeing a hank of yarn consisting in suspending the hank from a rotating roller, spraying dye liquor simultaneously on to the inside and outside of a hanging part of the hank by opposed spray jets, continuing to revolve the roller after the cutting 011 of the jets when complete impregnation of the hank has been effected,
and finally washing the hank whilst it continues to be moved by the rotating roller substantially as set forth. 7
5. Method of dyeing hanks of yarn consisting in sus ending a number of hanks from a plura ity of rollers, spraying dye liquor simultaneously on to the inside and outside of hanging parts of the hanks by opposed spray jets some of which are situated within the hanks and some of which are situated between the hanks, and finally performing finishing steps upon the hanks whilst they remain suspended from the rollers after the completion of the impregnation by spraying substantially as set forth.
