Problems solved by technology

[0003] 1. The clustering and drafting properties are not very good
[0004] 2. The carding passability is poor, and the antistatic performance is poor, and the static electricity generated in each process cannot be effectively suppressed.
[0005] 3. The smoothing performance is not good, and the phenomenon of roller winding and white powder in the spinning process cannot be effectively suppressed;
[0006] 4. Temperature and humidity have a great influence on spinnability
[0007] Therefore, the existing auxiliary agents have the disadvantages of many broken ends, poor forming, and many broken ends in the spinning process.

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.

[0044] According to the ratio of 6:1, mix the above-mentioned components A and B evenly to make polyester staple fiber oil.

Abstract

The oil preparation for spinning dacron staple fiber includes two components of component an and component B in the weight ratio of 3-6. The component A has mixed dodecyl and tetradecyl alcohol with weight ratio between dodecyl alcohol and tetradecyl alcohol of 1-3, P2O5 and NaOH as main material and produces phosphate sodium salt of the mixed alcohol. The component B is compounded with fatty alcohol-polyoxyethyleneether ammonium sulfate coconut oil biethyl alcohol acylamine in the weight ratio of 1 to 0.5-1.5. The present invention has low production cost, and results in less breaking during spinning and good forming performance.

Description

Technical field: [0001] The invention relates to an oil agent for polyester staple fiber spinning and a preparation method thereof. It belongs to the technical field of spinning aids. Background technique: [0002] Oil agent for polyester staple fiber spinning is an important textile auxiliary that is indispensable in the spinning process of polyester staple fiber. Because polyester staple fiber does not have the natural colloid and oil film that natural fibers have, it has poor hygroscopicity and is non-conductive. In the spinning process, natural colloid can play the role of antistatic, bunching and moisture absorption, and make the fiber have good heat resistance and smoothness. The polyester fiber yarn just coming out of the yarn head is dry. This dry yarn will absorb the moisture in the surrounding air and elongate. The process cannot be processed. In addition, polyester staple fiber is a poor conductor of electricity. Polyester staple fiber moves at a high speed du...
