Abstract

The invention discloses a dyeing method with crude salt as the reactive dye accelerant. The method comprises the steps of preparing dye liquor with 3-4 g/L acrylic acid-2-acrylamide-2-methyl propane sulfonic acid multipolymer, 3-4 g/L N-methyl pyrrolidone, 1-2 g/L polyoxyethylene sorbitan aliphatic ester, 3-4 g/L maleic acid-acrylic acid copolymer, 2-3 g/L ethylenediamine tetraacetic acid disodium, 3-4 g/L salicylic acid, 3-4 g/L hydroxy propyl methylcellulose, 2-3 g/L hydrolytic polymaleic anhydride, 140 g/L crude salt and 10 g/L dyeing auxiliary; placing fabric in the dye liquor with a dyebath ratio of 3:20, increasing temperature to 97 DEG C at the speed of 10 DEG C/min, adding 22 g/L sodium carbonate for color fixation, conducting heat preservation for 3 h, and then conducting washing, soaping, washing and drying. By the adoption of the method, dyeing defects and low coloring rate of fabric caused when crude salt serves as the dye accelerant during dyeing are avoided, and the quality of a prepared product is consistent with that of a product made with the conventional process.

Description

technical field [0001] The invention relates to a dyeing method using coarse salt as a dyeing accelerator for reactive dyes. Background technique [0002] During exhaust dyeing with reactive dyes, due to the certain charge repulsion between the dye and the fiber, it is necessary to add a large amount of neutral electrolyte as a dyeing accelerator to promote the adsorption of the dye on the fiber. In the actual production process, industrial salt or industrial sodium sulfate is generally used as a dyeing accelerator, but its price is relatively high, which brings a certain burden to the production cost of the printing and dyeing factory. Coarse salt is the crystallization of sea water or salt water in salt wells, salt ponds, and salt springs after decoction, that is, natural salt, which is unprocessed large-grained salt. Yuan Mingfen; but coarse salt contains impurities such as calcium, magnesium, iron, zinc, copper, etc., and the above-mentioned metal ions are easy to compl...
