[0073] A kind of preparation method of hot and humid comfortable polyester fiber DTY yarn for winter, the steps are as follows:
[0074] (1) Preparation of oiling agent for oiling: 15-crown ether-5 and isomeric tridecanol polyoxyethylene ether phosphate potassium salt, trimethylolpropane laurate and sodium pentadecylsulfonate in After mixing evenly at room temperature, add it to 10# mineral oil and stir evenly at 43°C for 1.5 hours to obtain the oil agent. In parts by weight, the addition amount of each component is as follows: 10# mineral oil is 2 parts; 15 parts of propane laurate; 70 parts of 15-crown-5; 10 parts of potassium isotridecyl polyoxyethylene ether phosphate; 7 parts of sodium pentadecyl sulfonate; prepared oil The content of crown ether in the agent is 67.30wt%. The high temperature resistance of the oil agent is excellent. After heat treatment at 200°C for 2 hours, the thermal weight loss is 13wt%. The viscosity of the oil agent is low. 28.1mm 2 / s, the kinem...

[0080] A kind of preparation method of hot and humid comfortable polyester fiber DTY yarn for winter, the steps are as follows:
[0081] (1) Preparation of oiling agent for oiling: mix 2-hydroxymethyl-15-crown-5 with potassium salt of tetradecyl phosphate, trimethylolpropane laurate and sodium pentadecylsulfonate After mixing evenly at room temperature, add it to 11# mineral oil and stir evenly at 48°C for 3 hours to obtain an oil agent. The addition amount of each component is as follows in parts by weight: 11# mineral oil is 8 parts; 10 parts of propane laurate; 85 parts of 2-hydroxymethyl-15-crown-5; 11 parts of potassium tetradecyl phosphate; 5 parts of sodium pentadecylsulfonate; The content of crown ether in the oil is 70.83wt%. The high temperature resistance of the oil is excellent. After heat treatment at 200°C for 2 hours, the thermal weight loss is 11wt%. The viscosity of the oil is low. Viscosity is 30.1mm 2 / s, the kinematic viscosity after the concentration is ...
