Problems solved by technology

Large foreign companies such as Bayer, BASF and other chemical companies have started research on environmental protection color repairing agent products as early as the early 1990s, and products have been put on the market successively, but the price is very expensive, and the price of finished products with an effective content of about 30% is generally low. They are all above 30 yuan / kg, and few manufacturers in China use them

Abstract

The invention discloses a dressing agent for repairing dyeing defects including colored spots, color differences, streakiness and the like generated in polyester dyeing and a preparation method thereof. The products of dressing agent class used in the domestic market at present can not conform to the European Union environment standard, and the foreign environmental protection dressing agent has very expensive price with little use in the domestic manufacturers. The dressing agent is compounded by using a swelling agent, an emulsion dispersant and a solvent as raw materials. The invention hassupranormal migration property and ideal repair effects, and effectively solves various dyeing defects generated after polyester and blended fabric thereof are dyed, and the fabric dyed by the dressing agent conforms to the European Union environment standard through detection.

Description

technical field [0001] The invention relates to polyester fabric dyeing, in particular to a color repairing agent for repairing dyeing defects such as color spots, color differences and stripes produced in polyester dyeing and a preparation method thereof. Background technique [0002] When dyeing polyester and its blended fabrics, there will be dyeing defects such as color flowers, color difference, stripes or deep spots. The reasons are many, such as fabrics, equipment, dyes, processes, leveling agents and so on. For the dyeing defects that have been caused, dyeing factories generally use dye transfer and repairing agents for repairing. At present, most of the color repairing agent products used in China are made of phenol, aromatic amine, biphenyl, etc. Carriers with such structures pollute and poison the environment, and nonylphenol ethoxylates have environmental factors such as poor biodegradability and high toxicity. [0003] Developed countries such as Europe have s...
