PIGMENT PRINTING COMPOSITION BASED ON POLYURETHANE COMPONENTS (VERSIONS) Russian patent published in 2017 - IPC D06P1/46 

FIELD: textile and paper.

SUBSTANCE: invention relates to dyeing-and-finishing works in textile industry, namely, to pigment printing compositions for colouration of textile materials, and can be used for producing effective to use small-component compositions for weaving textile products. Pigment printing composition based on polyurethane components for finishing textile materials, which contains a pigment, a binder – preparations Aquapol 11 or Aquapol 15 representing hydrophilic polyurethaneureas, which do not contain free isocyanates, as well as a thickener – a mixture of modified alginate thickener Manutex RS and associative polyurethane thickener Laprol DZ in the ratio of 10:1 or other synthetic thickeners: Lutexal HEF (f. BASF), or Thickener N (f. CePolTex), or Rheovis PU (f. BASF), and additionally contains a plasticizer (Weichmacher HP or Tratskan GF), g/kg: Pigment – 10–50; Aquapol 11 (15) – 80–200; Softener – 20; Thickener (Manutex RS (4.5 %) 10:1; with Laprol DZ) up to kg. Pigment printing composition based on polyurethane components for finishing textile materials contains a pigment, a binder – PUD Aquapol 12, or Aquapol 21, or Aquapol 23 at the ratio of 1:1 with PVA, as well as a thickener based on synthetic thickeners: Lutexal HEF (f. BASF), or Thickener N (f. CePolTex), or Rheovis PU (f. BASF), and additionally contains a plasticizer (Weichmacher HP or Tratskan GF.), g/kg: Pigment – 30; Aquapol 12 (21, 23) – 90; PVA – 90; Thickener (Lutexal HEF) – 15; Softener – 20; Water up to 1,000.

EFFECT: higher resistance of dyes to dry and wet friction, improved softness of printed articles feel of cloth, reduced penetration of printing ink onto the reverse side of the material, no “clogging” of screens for silk-screen printing, reduced consumption of textile auxiliaries in the printing composition, saving costs and higher environmental safety of the pigment printing process.
