Embodiment 1
[0040] A kind of composite leveling auxiliary agent for textiles, in parts by weight, consists of the following components:
[0054] In the above-mentioned embodiment, the preparation method of described a kind of composite leveling auxiliary agent for textile, comprises the following technical steps:
[0055] (1) According to the proportion, mix polyvinylpyridine, polyvinylpyrrolidone, hydroxyethyl butyl ether and isopropanol, heat to 30-50°C, stir and disperse evenly;
[0056] (2) Dissolve ammonium dodecylbenzenesulfonate, potassium ricinoleate and sodium methylene dinaphthalenesulfonate in water and disperse evenly;
[0057] (3) Mix the products of step (1) and step (2), stir evenly, and cool down to room temperature to get the fin...

Abstract
The invention discloses a compound level dyeing assistant for textile, and a preparation method thereof. The compound level dyeing assistant for the textile is composed of the following components by weight: 1-3 parts of polyvinyl pyridine, 2-6 parts of polyvinylpyrrolidone, 1-3 parts of hydroxyethyl butyl ether, 0.4-0.8 part of ammoniumdodecylbenzenesulfonate, 0.3-0.6 part of potassium castorate, 0.1-0.3 part of sodiummethylene dinaphthalene sulfonate, 10-20 parts of isopropanol and 12-18 parts of water. Compared with a conventional level dyeing assistant, the compound level dyeing assistant provided by the invention has the following beneficial effects that (1) the compound level dyeing assistant has excellent dispersibility for dispersing dyes; (2) the compound level dyeing assistant makes the dyes not occur coacervation; (3) the compound level dyeing assistant has small foamability; (4) the compound level dyeing assistant has excellent migration performance; (5) the compound level dyeing assistant has no achromatic property; and (6) the compound level dyeing assistant has relatively good electrolyte resistance.
Description
technical field [0001] The invention belongs to the technical field of textile auxiliaries, and more specifically relates to a composite leveling auxiliaries for textiles. Background technique [0002] Streaks and dye spots appear in fabric dyeing, which are often closely related to the quality of the fiber itself. On the one hand, it is due to the uneven physical and chemical structure of the fiber; on the other hand, it is caused by improper pre-dyeing treatment and dyeing conditions. [0003] There are many methods of level dyeing, and their purpose is: 1. To distribute the dye molecules evenly on the surface of the fiber; 2. To diffuse the dye distributed on the surface of the fiber to the inside of the fiber. The above goals can be achieved by controlling the dyeing speed, controlling the uniform concentration and temperature of the dye bath, using dyes with good dye transfer properties, using dye transfer agents and carriers, and dyeing at high temperature for a long t...
