Abstract

The invention discloses weft printing dye. The weft printing dye is composed of the following components, by mass, 70-90% of bottoming liquid and 10-30% of color paste liquid. The bottoming liquid is composed of the following components: 4-4.5% of naphthol AS, 3-3.5% of NaOH with the mass concentration being 30%, 2-2.8% of fatty alcohol-polyoxyethylene ether, 1-1.5% of carbamide, and the balance water. The color paste liquid is composed of the following components: 1-1.3% of methyl-2-nitroaniline, 1.8-2.2% of hydrochloric acid with the mass concentration being 30%, 0.5-0.9% of sodium nitrite, 0.3-0.6% of sodium acetate, 0.9-1.3% of acetic acid, 10-15% of starch-gum tragacanth paste, 9-12% of sodium alginate paste, 2-2.5% of adhesive, and the balance water. Compared with the prior art, the weft printing dye has the advantages that under the action of the moderate adhesive, the sodium alginate paste and the starch-gum tragacanth paste, the adhesiveness of the dye is improved greatly, and prints have good toughness and abrasive resistance.

Description

technical field [0001] The invention relates to a dye, in particular to a weft printing dye for clothes. Background technique [0002] Printing and weft printing is just one of many printing and dyeing technologies. After the color development treatment is required, it will produce a peculiar hazy effect. The key to the weft printing process using insoluble azo dyes is the selection of naphthols. The affinity of naphthols to yarns can neither If it is too large, it should not be too small. If the affinity is too small, it will easily cause warp yarn staining during the weaving process, and the printing effect will not meet the requirements. After printing, it is necessary to wash off the unreacted naphthol and floating color on the surface. A certain concentration of caustic soda and sodium bisulfite solution must be used for reduction cleaning to effectively remove the floating color and ensure the printing quality and effect. The printing process is an ingenious combinati...
