JOHN DAVIES, OF MANCHESTER, ENGLAND.
Letters Patent No. 60,148, dated December 4, 1866.
TO ALL WHOM IT MAY CONCERN: I I
Be it known that I, JOHN DAVIES, of Manchester, in the county of Lancaster, kingdom of Great Britain and Ireland, have invented an improvement in the Treatment of Yarns or Threads; and I do hereby declare the following to be a full, clear, and exact description of the same.
My invention relates to the preparation and treatment of yarns or threads when in the form of cops, or when wound onto bobbins or spools, so as to enable them to receive a rapid dye in passing ontoithe beam, or when woven with woollen or silk weft; and the invention is designed to render cops or bob ins of yarn in such a con ditionethat when they are subjected to such rapid dyeing theyshall become impregnated and permeated with the dyeing or coloring matter.
The invention consists in boiling cops, bobbins, or spools of yarn or thread, in asolution of sumac catechu,
or other solution containing tannin, for about twenty-four hours, (the strength of such solutions may vary, but,
for example, three pounds of sumac may be used to ten pounds of cotton,) or in keeping the said yarn steeped in a hot solution of tannin until every fibre and thread is permeated and impregnatedlwith the solution, which state of saturation may be ascertained by cutting a cop through the middle, and applying to the part cut a solution of iron, which will cause a change of color, and if the saturation be sufiicient, the color will be even and regular from the outside to the centreof the cop. The yarn thus mordanted in the cop is dried; it is, then wound and warped onto the warpers beams by ordinary machinery; and afterwards passed through the dyeing liquors and size; it is then dried and passes direct in a co'ntinuous course onto the beam ready for the loom.
By this previous preparation, I can dye the yarn or warp, either by mixing the dyeing materials together, (as in printing,) either with or without size, passing the warp through and drying it as it passes to the beam, or the liquors may be kept separate in boxes, as in ordinary warp dyeing, and the yarnpassed through in the extended state and dried, and then passed onto the weavers beam.
I claim as my invention, and desire to secure by Letters Patent, cops or bobbins of yarn or thread saturated with a solution containing tanning matter for the purpose specified.
In testimony whereof I have signed my name to this specifiation in the presence of two subscribing witnesses.
, JOHN DAVIES.
