Abstract:
The use is disclosed of hydrophilically modified polyisocyanates in the field of textiles: (i) as cross-linking agents for binders used in pigment dye liquors for dying textiles, (ii) in the form of aqueous dispersions which are substantially free of organic solvents and other emulsifiers, for finishing textiles, or (iii) for the production of textiles with wash-fast lustres.
Abstract:
Gemusterte Textilien werden dadurch hergestellt, daß man gefärbtes Textilmaterial mit einem geeigneten Farbhaltemittel bedruckt und anschließend durch Auswaschen des Farbstoffes an den nicht bedruckten Stellen das Muster erzeugt. Als Farbhaltemittel eignen sich vor allem hydrophil modifizierte Polyisocyanate zusammen mit geeigneten Bindemitteln.

Abstract:
The claims concern the use of hydrophilic modified polyisocyanates (I) in combination with (a) sizes (II) cured with (I) for producing permanently sized yarns and (b) (II) and indigo for 1-stage sizing and dyeing of yarns or dyeing and printing of fabrics.
Abstract:
The use of hydrophilically-modified polyisocyanates (I) as crosslinkers for binders used in aq. pigment dye baths for dyeing textiles is claimed. Also claimed is a process for dyeing textiles in aq. pigment dye baths using (I) as crosslinker for the binder. Also claimed are aq. dye baths for the above process, contg. 0.01-10 wt.% (I) in addn. to pigments, binders, water and conventional additives.
