Examples
example 1
[0037] Group A takes 80g of dodecyl and tetradecandyl alcohol in a ratio of 2:1, P 2 o 5 60g is placed in the reaction vessel and reacts to generate mixed alcohol phosphate, then add 50% NaOH 125g and H 2 O 735g reacted to generate mixed alcohol phosphate sodium salt; Component B: Take 1 part of fatty alcohol polyoxyethylene ether ammonium sulfate and 1 part of coconut oil diethanolamide and mix evenly.
[0038] According to the proportioning ratio of 4: 1, the above-mentioned components A and B are mixed evenly to make the polyester staple fiber oil of the present invention.
example 2
[0040] Component A Take dodecanol 100g, P 2 o 5 58g, 50% NaOH 120g and H 2 O 722g and the remaining 1 are the same as Example 1; Component B Take 2 parts of fatty alcohol polyoxyethylene ether ammonium sulfate, and 1 part of coconut oil diethanolamide and mix well.
[0041] According to the proportioning ratio of 5: 1, the above-mentioned components A and B are uniformly mixed to prepare the polyester staple fiber oil of the present invention.
example 3
[0043] Component A Take 110g of dodecanol and tetradecandyl alcohol in a ratio of 3:1, P 2 o 5 63g, 50% NaOH 128g and H 2 O 700g, the rest are the same as in Example 1; Component B Take 1 part of fatty alcohol polyoxyethylene ether ammonium sulfate, 1.5 parts of coconut oil diethanolamide and mix well.
