Embodiment 1
[0062] A kind of preparation method of military soft polyester industrial yarn with high uniformity, the steps are as follows:
[0063] (1) Preparation of oiling agent for oiling;
[0064] Mix 2-hydroxymethyl-12-crown-4 with potassium dodecyl phosphate, trimethylolpropane laurate and sodium dodecylsulfonate at room temperature and add to 9# mineral oil and uniformly stirred at 40°C for 1 hour to obtain an oil agent. The addition amount of each component is as follows in parts by weight: 2 parts of 9# mineral oil; 10 parts of trimethylolpropane laurate; 2-methylolpropane laurate Base-12-crown-4 is 90 parts; Potassium dodecyl phosphate is 8 parts; Sodium dodecyl sulfonate is 3 parts; The content of crown ether in the prepared oil is 79.6wt%. The high temperature resistance of the agent is excellent, and the thermal weight loss after heat treatment at 200°C for 2 hours is 14.5wt%; the viscosity of the oil agent is low, and the kinematic viscosity is 29.6mm at (50±0.01)°C 2 / s, ...
Embodiment 2
[0069] A kind of preparation method of military soft polyester industrial yarn with high uniformity, the steps are as follows:
[0070] (1) Preparation of oiling agent for oiling;
[0071] Mix 15-crown ether-5 with potassium tridecyl alcohol polyoxyethylene ether phosphate, trimethylolpropane laurate and sodium pentadecylsulfonate at room temperature and add to 10# mineral oil and uniformly stirred at 43°C for 1.5h to obtain an oil agent. The addition amount of each component is as follows in parts by weight: 2 parts for 10# mineral oil; 15 parts for trimethylolpropane laurate; 15 parts for 15-crown Ether-5 is 70 parts; isomeric tridecanol polyoxyethylene ether phosphate potassium salt is 10 parts; sodium pentadecylsulfonate is 7 parts; the content of crown ether in the prepared oil agent is 67.30wt%, The oil agent has excellent high temperature resistance, and the thermal weight loss is 13wt% after heat treatment at 200°C for 2 hours; the viscosity of the oil agent is low, a...
Embodiment 3
[0076] A kind of preparation method of military soft polyester industrial yarn with high uniformity, the steps are as follows:
[0077] (1) Preparation of oiling agent for oiling;
[0078] Mix 2-hydroxymethyl-15-crown-5 with tetradecyl alcohol phosphate potassium salt, trimethylolpropane laurate and sodium pentadecylsulfonate at room temperature and add to 11# mineral in oil and uniformly stirred at 48°C for 3 hours to obtain an oil agent. The addition amount of each component is as follows in parts by weight: 8 parts for 11# mineral oil; 10 parts for trimethylolpropane laurate; 10 parts for 2-hydroxy 85 parts of methyl-15-crown-5; 11 parts of potassium tetradecyl alcohol phosphate; 5 parts of sodium pentadecylsulfonate; the content of crown ether in the prepared oil is 70.83wt% , the high temperature resistance of the oil is excellent, the thermal weight loss is 11wt% after heat treatment at 200°C for 2 hours; the viscosity of the oil is low, at (50±0.01)°C, the kinematic vi...
