[0019] Example 1
[0020] The method for preparing a spinning finish for polyester filament POY includes the steps:
[0021] (1) Prepare smoothing agent, weigh C8~C12 fatty alcohol oxyethylene oxide isopropylene random polyether and white oil at a mass ratio of 1:1, mix and stir evenly, and set aside.
[0022] (2) Accurately weigh 15% of emulsifier, 15% of smoothing agent, 10% of antistatic agent, 50% of deionized water, and 10% of additives based on weight percentage, and add emulsifier, smoothing agent and antistatic agent in order in the reactor. Stir and mix the electrostatic agent uniformly to obtain a mixed oil. The stirring speed is 550r / min, the stirring time is 40min, and the stirring temperature is 35℃.
[0023] (3) Add additives while stirring in deionized water, stir evenly for 10 minutes and then add the mixed oil while stirring. After the mixed oil is added, continue stirring for 30-60 minutes to obtain the product.

[0025] The method for preparing a spinning finish for polyester filament POY includes the steps:
[0026] (1) Prepare a smoothing agent. Weigh C12~C18 fatty acid amide polyoxyethylene ether and C16-C18 alcohol at a mass ratio of 1:1, mix and stir evenly, and reserve, where the weight percentage of C18 alcohol in C16~C18 fatty alcohol is 70%.
[0027] (2) According to weight percentage, accurately weigh emulsifier 10%, smoothing agent 22%, antistatic agent 10%, deionized water 50%, additives 8%, and then add emulsifier, smoothing agent and antistatic agent to the reactor. Stir and mix the electrostatic agent uniformly to obtain a mixed oil. The stirring speed is 600r / min, the stirring time is 40min, and the stirring temperature is 35°C.
[0028] (3) Add additives while stirring in deionized water, stir evenly for 15 minutes and then add the mixed oil while stirring. After the mixed oil is added, continue stirring for 30-60 minutes to obtain the product.

[0030] The method for preparing a spinning finish for polyester filament POY includes the steps:
[0031] (1) Prepare a smoothing agent, weigh C8~C12 fatty alcohol oxyethylene oxide isopropylene random polyether and C16-C18 alcohol according to the mass ratio of 2:1, mix and stir evenly, and set aside, of which C16~C18 fatty alcohol The weight percentage of C18 alcohol is 70%.
[0032] (2) Accurately weigh 13% of emulsifier, 20% of smoothing agent, 8% of antistatic agent, 45% of deionized water, and 14% of additives by weight percentage, and add emulsifier, smoothing agent and antistatic agent in order in the reactor. Stir and mix the electrostatic agent uniformly to obtain a mixed oil. The stirring speed is 600r / min, the stirring time is 40min, and the stirring temperature is 35°C.
[0033] (3) Add additives while stirring in deionized water, stir evenly for 15 minutes and then add the mixed oil while stirring. After the mixed oil is added, continue stirring for 3...
