Embodiment 1

[0026] A preparation method of polyester spinning oil, characterized in that the specific preparation steps are:

[0027] (1) According to the mass ratio of 3:2:2:1, take fatty acid polyethylene glycol ester, pentaerythritol oleate, sodium lauryl sulfonate and ethylhexyl palmitate and mix respectively to obtain mixed oil, and then Weigh the gum arabic in a mass ratio of 1.5:10 and add it to deionized water, mix and stir after heating to obtain a gum arabic solution, add a surfactant, let stand for 10min, then stir and mix at a speed of 2000r / min to obtain a mixed solution;

[0028] (2) Add the mixed solution into the emulsifier twice, add the mixed oil at the same time into the emulsifier, after emulsification, use a high-pressure homogenizer to homogenize to form an emulsion, and carry out centrifugal spray drying on the emulsion to obtain high temperature resistant Microencapsulated mixed oil, set aside;

[0029] (3) In parts by weight, respectively select 15-20 parts of po...

Embodiment 2

[0042]According to the mass ratio of 3:2:2:1, weigh fatty acid polyethylene glycol ester, pentaerythritol oleate, sodium lauryl sulfonate and ethylhexyl palmitate and mix them to obtain a mixed oil, and then weigh them according to the mass ratio 1.5:10 Weigh the gum arabic and add it to deionized water, heat it to 65°C and mix and stir to get the gum arabic solution, add 7% surfactant in the gum arabic solution, let stand for 10 minutes, and stir and mix at 2000r / min for 15 minutes To obtain a mixed solution; move the mixed solution into an emulsifier, and add mixed oil of 1.5 times the quality of the mixed solution to the emulsifier, and emulsify at a speed of 5000r / min for 10min, after emulsification, use a high-pressure homogenizer to homogenize under the condition of 15000psi 60s to form an emulsion, and the emulsion is spray-dried to obtain a high-temperature-resistant microencapsulated mixed oil; by weight, 15 parts of polyoxyethylene sorbitan monolaurate, 8 parts of sor...

example 3

[0045] According to the mass ratio of 3:2:2:1, weigh fatty acid polyethylene glycol ester, pentaerythritol oleate, sodium lauryl sulfonate and ethylhexyl palmitate and mix them to obtain a mixed oil, and then weigh them according to the mass ratio 1.5:10 Weigh the gum arabic and add it into deionized water, heat it to 70°C, mix and stir to get the gum arabic solution, add 5% surfactant of the gum arabic solution, let stand for 10min, and stir and mix at 1000r / min for 10min To obtain a mixed solution; move the mixed solution into an emulsifier, and add mixed oil of 1.2 times the quality of the mixed solution to the emulsifier, and emulsify at 3000r / min for 5min, after emulsification, use a high-pressure homogenizer to homogenize under 10000psi 30s to form an emulsion, and the emulsion is spray-dried to obtain high-temperature-resistant microencapsulated mixed oil; in parts by weight, 10 parts of polyoxyethylene sorbitan monolaurate, 4 parts of sorbitan monolaurate, and 4 parts o...

Abstract

The invention discloses a preparation method of a polyester spinning oil. An emulsifier in the invention can form an oil film on the surface of a chemical fiber, and a hydrophilic matrix in the oil film adsorbs moisture in air in order to form a continuous water film on the surface of the fiber, so accumulation of static charges, caused by friction, is reduced, apron winding, roller winding, cylinder winding and other undesirable phenomena are avoided, broken filaments and broken ends are reduced, and the quality of a fiber product is ensured.

Description

technical field [0001] The invention relates to a preparation method of polyester spinning oil, belonging to the technical field of textile auxiliaries. Background technique [0002] In my country, the trade name of PET polyester (polyethylene terephthalate) silk fabrics is called polyester. Polyester spinning generally adopts high-speed spinning-drawing and twisting process in China, that is, the two-step combination of pre-oriented yarn or partially oriented yarn and stretched textured yarn, referred to as POY-DTY process. In order to make polyester POY have a higher degree of orientation and crystallinity, the spinning speed is usually in the range of 3000-4600m / min. The faster the spinning speed, the higher the production efficiency. The high-speed spinning of polyester POY requires that the spinning oil used should have good smoothness, bunching and antistatic properties, so as to ensure good tow formation, proper embracing, and less broken ends of wool. In addition, ...
