Abstract

The invention relates to a preparation method of a degreasing and level dyeing composite emulsifier for polyester fabrics, and belongs to the field of textile aids. In the traditional process, degreasing and level dyeing are performed in two steps, such that the production process is long, and the consumption of water and electricity is more. According to the present invention, the composite emulsifier is formed by mixing the following components by mass: 18-22% of tristyrylphenol polyoxyethylene polyoxypropylene ether benzoate, 8-12% of tristyrylphenol polyoxyethylene polyoxypropylene ether ammonium sulfate, 8-12% of isotridecanol polyoxyethylene polyoxypropylene ether sodium sulfate, 3-7% of isotridecanol polyoxyethylene ether, and the balance of water; the composite emulsifier does notcontain phosphorus, has good degreasing property, good dyeing retarding property and good transferability, and has little influence on the dye uptake rate of dyes; and the degreasing and the dyeing are integrated so as to shorten the dyeing and finishing process, improve the production efficiency, reduce the production cost, and achieve the purposes of energy saving and emission reduction.

Description

technical field [0001] The invention relates to the field of textile auxiliaries, in particular to a preparation method of a composite emulsifier for degreasing and leveling dyeing of polyester fabrics. Background technique [0002] At present, the degreasing agents and leveling agents with better performance used in textile processing on the market contain phosphorus. The discharge of these phosphorus into the water body can easily cause eutrophication of the water body, resulting in an imbalance in the species distribution of the water ecosystem and destroying the water quality. The flow of matter and energy in the ecosystem, so it is of great significance to non-phosphorize the textile auxiliaries used in textile processing. [0003] Polyester is an important variety of synthetic fibers, and disperse dyes are generally used for dyeing. However, in the dyeing process of polyester, dyeing defects such as staining spots and streaks often occur. There are many reasons for u...
