Description

Technical Field

[0001] The invention relates to the technical field of spinning oils, and in particular to a low-oil-consumption polyester FDY spinning oil for WINGS equipment and a preparation method thereof. Background Art

[0002] At present, chemical fiber spinning equipment is generally developing towards integration, stability, high efficiency, energy conservation and environmental protection. WINGS spinning equipment is a device equipped with an integrated control box and designed according to the concept of independent unit control. Compared with conventional spinning equipment, it has the advantages of low space cost, production line integration, and high production efficiency. In addition, the hot rollers of this equipment are integrated in a hot box, and the heat generated by the roller heating will continue to exist in the box, with low energy loss. At the same time, when using WINGS equipment for spinning, the yarn is not oiled before drawing, and the yarn will not cause heat loss of the hot roller due to the evaporation of oil and water when passing through the hot roller. Oiling the yarn after stretching and shaping can also reduce the emission of pollutants such as oil smoke in production, and has the technical effect of environmental protection and low power consumption.

[0003] The spinning speed of WINGS equipment is three to four times that of ordinary spinning equipment. Therefore, the spinning oil suitable for WINGS equipment needs to have better penetration wettability and splash resistance. Some spinning oils for WINGS equipment are also disclosed in the prior art. For example, Publication No. CN103061115A discloses a polyester FDY oil for WINGS equipment production and its production method. The oil has the advantages of stable oil emulsion, good viscosity characteristics, no obvious corruption phenomenon, good spinnability, no broken ends, good yarn cake linear shape, high superior rate, uniform dyeing, high M rate, good oil bundling, uniform fiber oil content, stable quality, etc. Although the spinning oil disclosed in the prior art can meet the use of WINGS equipment, the applicant found in the process of use that there are problems of low oiling efficiency and easy splashing when using the spinning oil of WINGS equipment in the prior art. When producing polyester FDY with an oil content of 1%, the oil consumption is 1.5%, and the oil loss can reach 30%, which is high. Summary of the invention

[0004] In order to overcome the problems of low oiling efficiency, easy splashing and high oil consumption of WINGS equipment spinning oil in the prior art, the present application provides a low-fuel-consumption polyester FDY spinning oil for WINGS equipment and a preparation method thereof. A smoothing agent and an anti-splashing agent are added to the FDY spinning oil, which significantly improves the oil's penetration wettability, oil film strength and anti-splashing properties, thereby significantly reducing the oil consumption when the FDY spinning oil is used.

[0005] The specific technical scheme of the present invention is:

[0006] A low-oil-consumption polyester FDY spinning oil for WINGS equipment, comprising a smoothing agent and an anti-splashing agent.

[0007] The present application provides a low-fuel-consumption polyester FDY spinning oil for WINGS equipment, the components of which include a smoothing agent and an anti-splashing agent, wherein the smoothing agent can significantly improve the oil's penetration wettability and oil film strength on the fiber, the high wetting permeability can enable the oil to be quickly wrapped around high-speed fiber filaments, the high oil film strength can ensure that the oil film wrapped around the fiber filaments will not be easily destroyed, thereby ensuring that the oil consumption when the oil is used in the WINGS equipment is significantly reduced. In addition, in order to further enhance the bonding strength between the oil and the fiber filaments, the present application adds an anti-splashing agent to the oil, the anti-splashing agent can significantly improve the oil's anti-splashing property, and can ensure that the oil will not easily splash when the oil wraps around high-speed running fiber filaments, thereby further reducing the oil consumption when the oil is used in the WINGS equipment.

[0008] Furthermore, the lubricant comprises synthetic ester and mineral oil, and the synthetic ester comprises a branched structure.

[0009] Preferably, the synthetic ester includes one or more of pentaerythritol stearate, isotridecyl stearate, isooctyl oleate and pentaerythritol laurate.

[0010] The reduction of branched structures in the component structure of the smoothing agent will significantly reduce the wetting and permeability of the smoothing agent. The increase of branched structures can enable the oil agent to quickly penetrate into the surface of the fiber. The surface of polyester fiber has a high affinity for organic functional groups. The branched structure of synthetic ester contains organic functional groups. Increasing the branched structure on the synthetic ester can significantly increase the affinity of the oil agent to polyester fiber, thereby significantly improving the penetration wettability of the oil agent and the oil film strength.

[0011] Furthermore, the anti-splash agent includes sulfur and / or phosphorus.

[0012] Preferably, the anti-splashing agent includes one or more of sulfurized olefin cottonseed oil, sulfurized fatty acid ester, sulfurized lard, di-n-butyl phosphite, ammonium salt of thiophosphate complex ester and nitrogen-containing derivatives of thiophosphate.

[0013] The component structure of the anti-splash agent mainly contains sulfur and / or phosphorus. Sulfides, phosphides and phosphorus-sulfur compounds contain sulfur-sulfur bonds, phosphorus-sulfur bonds, phosphate bonds and other chemical bonds. These chemical bonds can ensure the viscosity of the oil and form a three-dimensional network in the oil. When the oil collides with the fiber, it will not splash easily, thereby reducing the loss of the oil due to oil splashing during use.

[0014] Furthermore, the components also include emulsifier, antistatic agent, preservative additive and water.

[0015] The functions of the other components of the application are as follows:

[0016] Emulsifiers balance and stabilize the various components in the oil to form an emulsion;

[0017] Antistatic agent, which increases the antistatic property of the oil and reduces the static effect generated by fiber friction;

[0018] Anti-corrosion additives can increase the performance of oils and improve their stability and service life.

[0019] Furthermore, the mass parts of the components are:

[0020] 40-60 parts of smoothing agent,

[0021] Anti-splash agent 0.5-1 part,

[0022] Emulsifier 15-30 parts,

[0023] Antistatic agent 5-10 parts,

[0024] 0.5-2 parts of antiseptic additives,

[0025] 8-12 parts water

[0026] Preferably, the emulsifier includes one or more of ethylene oxide / propylene oxide polyether, castor oil polyoxyethylene ether, fatty acid polyoxyethylene ester, fatty amine polyoxyethylene ether and coconut oil diethanolamide, and the antistatic agent includes one or more of fatty alcohol succinic acid monoester sulfonate sodium, alkanolamide succinic acid monoester disodium salt, alkyl sulfate and isomeric fatty alcohol polyether phosphate salt.

[0027] Preferably, the preservative additives include one or more of potassium phenylacrylate, ethyl parahydroxybenzoate, propyl parahydroxybenzoate and hydroxyethyl hexahydrotriazine, and the preservative additives include one or more of antioxidant 425, antioxidant 330 and antioxidant 1520.

[0028] A method for preparing a low-fuel-consumption polyester FDY spinning oil for WINGS equipment comprises the following preparation steps: injecting components of the low-fuel-consumption polyester FDY spinning oil into a container and stirring, and filtering and refining the oil after the stirring is completed to prepare the low-fuel-consumption polyester FDY spinning oil for WINGS equipment.

[0029] Compared with the prior art, this application has the following technical effects:

[0030] (1) The spinning oil includes a smoothing agent. The branched structure of the smoothing agent can significantly improve the penetration wettability of the oil on the fiber and the oil film strength, and significantly reduce the oil consumption when the spinning oil is used;

[0031] (2) The spinning oil includes an anti-splashing agent, the structure of which includes sulfur and / or phosphorus. The anti-splashing agent can form a three-dimensional structure in the oil to reduce the splashing effect of the oil during the collision between the oil and the fiber, thereby further reducing the oil consumption when the spinning oil is used;

[0032] (3) The polyester FDY spinning oil emulsion for WINGS equipment provided in the present application is stable, has no obvious corruption during the long-term production process, has strong anti-corrosion properties, excellent antistatic properties, high smoothness, stable and uniform oil content of the yarn bundle, good spinnability, and low breakage rate.

[0095] Test example

[0096] According to the components of the above-mentioned Examples 1 to 7 and Comparative Examples 1 to 3, a polyester FDY spinning oil is prepared, and the preparation steps include: heating a stirrer to 40° C., adding various components of the polyester FDY spinning oil into the stirrer in proportion and stirring, and after stirring evenly, filtering with a 400-mesh filter to obtain a low-fuel-consumption polyester FDY spinning oil for WINGS equipment;

[0097]

[0098] The FDY spinning oils prepared in Examples 1 to 7 and Comparative Examples 1 to 2 were tested for physical properties. The test indicators included: appearance (25°C), emulsion stability (15% aq, standing for 72h), effective content (%), pH (1% aq), density (20°C, g / cm3), rotational viscosity (40°C, mPa·S), canvas sedimentation time (10% aqueous solution, s), oil film strength, surface tension (1% aqueous solution, 20°C, mN / m), conductivity (μs / cm), and the test results are shown in Table 1;

[0099] Table 1 Physical properties of polyester FDY spinning oils of Examples 1-7 and Comparative Examples 1-2

[0100] As shown in Table 1, the emulsions of the polyester FDY spinning oils of Examples 1 to 5 and Comparative Examples 1 to 2 have good stability, while the emulsions of Examples 6 to 7 have poor stability. The above results show that the polyester FDY spinning oils of Examples 1 to 5 and Comparative Examples 1 to 2 meet the basic requirements for use in spinning production and can be used as polyester FDY spinning oils, while the spinning oils of Examples 6 to 7 have poor stability and will delaminate after being stored for a period of time, which does not meet the basic requirements for spinning oils in spinning production.

[0101] The polyester FDY spinning oils of Examples 1 to 5 and Comparative Examples 1 to 3 were used to test spin 60 dtex / 24f semi-dull yarns, and the physical properties and dyeing conditions of the 60 dtex / 24f semi-dull yarns were tested. The test indicators included: breaking strength, breaking strength CV value, breaking elongation, breaking elongation CV value, oil content%, oil unit consumption%, boiling water shrinkage, yarn unevenness U value, dyeing uniformity, and the test results are shown in Table 2. As shown in Table 2,

[0102]

[0103] As shown in Table 2, the above experimental results show that the dyeing of the 60dtex / 24f semi-dull yarn treated in Examples 1 to 4 and Comparative Examples 1 to 3 is uniform, while the dyeing of the 60dtex / 24f semi-dull yarn treated in Example 5 is striped. From the dyeing results, it can be seen that the spinning oils of Examples 1 to 4 and Comparative Examples 1 to 3 can ensure the uniformity of dyeing of polyester fibers; compared with Comparative Example 3, the breaking strength and breaking elongation of the 60dtex / 24f semi-dull yarn in Examples 1 to 4 and Comparative Examples 1 to 2 are significantly higher than those in Comparative Example 3. Example 3. Further analysis shows that the difference between Example 4 and Comparative Example 2 is that no anti-splash agent is added in Comparative Example 2. From the results of the treated 60dtex / 24f semi-dull yarn, it can be seen that the breaking strength and breaking elongation of Example 4 are higher than those of Comparative Example 2, and the unit consumption of oil is lower than that of Comparative Example 2. It can be seen that the addition of anti-splash agent can further improve the degree of bonding between the oil and the fiber, significantly improve the performance of the oil, and reduce the oil consumption during use. By analyzing the unit consumption of oil, it can be seen that the oil consumption in Example 4 is reduced by 20% compared with Comparative Example 3.

[0104] After Example 4 and Comparative Examples 1 to 3 were used in WINGS equipment for 6 months, the oil residue and corruption were observed. The results showed that the oils in Example 4 and Comparative Example 2 did not corrupt, while Comparative Examples 1 and 3 were slightly corrupted. The difference between Comparative Example 1 and Example 4 is that no preservative was added. It can be seen that the addition of preservatives can effectively prevent the oil from corrupting and deteriorating, and can significantly improve the stability and practicality of the oil.
