Definitions

• This invention relates to an improvement in the art of dyeing.
• the invention consists in the various improvements hereafter described and claimed.
• I first impregnate textile yarns or fabrics or other materials such as furs, wool or leather with a soluble condensation product of urea or preferably thio-urea with formaldehyde, hereafter termed semi-condensate, and I then treat the impregnated material by dyeing or printing.
• the semi-condensate may be prepared by known processes, such as those for the manufacture of condensation products to the stage preceding gelatinization described in British Patents (Pollak) #157,416, #171,094, #181,014, #187,605, #193,420, #201,906, #206,512, #213,567 and #248,729.
• the semi-condensate is employed in the state of dilution suitable for the particular purposes intended, as for example where a slight effect is required, 2%% by weight of.
• the semi-condensate may be employed either coloured (by means of dyes, etc.) or clear.
• the material to be dyed may be impregnated with theIsemi-condensate uniformly or superficially to produce ingrain and all-over efiects, or may be impregnated to produce pattern effects.
• the impregnated material may be dyed before or after drying out the semi-condensate, but preferably drying precedes dyeing and/or printing so as to cause further con: densation of the semi-condensate and thus to convert it into an insoluble condensate in known manner.
• the semi-condensate may act as an activator of absorption, as a resist, or it may selectively absorb this or that element of a dye or mordant, or one or more v the grey, one is uniformly impregnated with semi-condensate and dried out, the other is left untreated; both are simultaneously immersed in a dye-bath of a suitable direct violet dyestuff and dyed; on simultaneous withdrawal 0f the cloths, the impregnated cloth will be found to have abstracted much more of the dye than the untreated cloth and to be of a deeper shade of heliotrope.
• the colours of the dyed fabric may be varied by substituting coloured condensate for clear and semi-condensate, when, in consequence of the semi-condensate abstracting additional colour from the dye-bath, the final colour of the semi-condensate may be altered.
• Impregnated material may also be printed with suitable dyes either in self-colour, or-
