Abstract

The invention relates to dispersive / active dye combination printing compound paste and a printing process thereof and belongs to the technical field of fabric printing. The paste is characterized by comprising the following components in parts by weight: 2 parts of sodium alginate, 0.9-1.1 parts of PTR and 72.6-90.6 parts of water. The printing process is characterized by comprising the step of preparing color paste from a dispersive dye, an active dye, compound paste, an alkali agent, urea and an auxiliary agent together to print, wherein the compound paste accounts for 42-48% by mass of the total material, the alkali agent accounts for 1.4-1.6% by mass of the total material and the urea accounts for 5.6-6.4% by mass of the total material. The dosage of sodium alginate can be reduced. The compound paste is great in structural viscosity and good in water holding property, so that a pattern of a fabric is unlikely to bleed, and the pattern is high in definition.

Description

technical field [0001] A disperse / reactive dye homogeneous printing composite paste and a printing process thereof belong to the technical field of fabric printing. Background technique [0002] Polyester-cotton fabric not only has the advantages of silky and stiff polyester fabric, but also has the advantages of moisture absorption and breathability of cotton fabric, and is deeply loved by consumers. The printing process of polyester and cotton fabrics should take into account the printing requirements of polyester fabrics and cotton fabrics, and the printing methods are diverse. On the market, most polyester-cotton fabrics are printed with paint, but paint printing has a series of shortcomings such as poor hand feeling, rubbing fastness, and low rubbing fastness. Dispersion / reactive homopolymer printing has the advantages of bright color, good hand feeling and high fastness, and has attracted more and more attention, but there are also a series of problems in homozygous p...
