Embodiment 1
[0026] A kind of tensio-active agent that one-bath process of woven fabric destaining is used, is made up of following components by weight percentage:
[0027] Sodium stearate accounts for 14.5% of the total weight, sodium dodecylbenzenesulfonate accounts for 23.4% of the total weight, nonylphenol polyoxyethylene ether accounts for 5.6% of the total weight, and the diffusing agent MF accounts for 37.8% of the total weight. The balance is water. Among them, nonylphenol polyoxyethylene ether is an adduct of nonylphenol and ethylene oxide, the hydroxyl value of polyoxyethylene ether is 85±3mgKOH / g, and the pH value is between 6-7, it is colorless Transparent liquid. Diffusion agent MF is sodium methylene bismethyl naphthalene sulfonate (C 23 h 18 o 6 S 2 Na).
[0028] The concrete preparation method of this tensio-active agent is as follows:
[0029] Calculated on the basis of 1kg of surfactant: 0.145kg of sodium stearate, 0.234kg of sodium dodecylbenzenesulfonate, 0.056k...
Embodiment 2
[0037] A kind of tensio-active agent that one-bath process of woven fabric destaining is used, is made up of following components by weight percentage:
