Description

Technical Field

[0001] The invention belongs to the technical field of spinning auxiliaries, and more specifically, relates to a fast wetting and penetrating FDY-WINGS spinning oil, a preparation method and application thereof. Background Art

[0002] The development trend of chemical fiber filament spinning equipment revolves around energy saving, high efficiency, green environmental protection and multifunctional application. Germany's Oerlikon Barmag closely follows the market trend to carry out technological innovation. The newly launched WINGS (Winding Integrated Godet Solution) equipment breaks the traditional drafting and shaping process that requires oil protection in the chemical fiber spinning process. It has the characteristics of high efficiency and energy saving, compact structure, easy spinning operation, low waste rate and good filament quality, and is increasingly recognized by the chemical fiber market. WINGS spinning equipment adopts the solution of first hot roller drafting and shaping, then oiling, and finally winding; this is completely different from the traditional FDY equipment's one-step drafting process of first oiling, then two pairs of hot rollers drafting and shaping, and finally winding. The direct contact between the oil and the hot roller is avoided during the spinning process, which can save more than 20% of the energy consumption caused by the volatilization of water in the oil. Correspondingly, the oiling process of WINGS spinning equipment is different from that of conventional FDY equipment. The speed of conventional FDY equipment during oiling is 2000-3000m / min, while the speed of WINGS equipment during oiling is 4000-5000m / min, which is more than double the oiling speed of conventional FDY equipment. Therefore, the spinning oil sprayed from the oil nozzle of WINGS equipment must have a high oil emulsion concentration and rapid wetting and penetration, so that the spinning oil can quickly wet and spread on the surface of the polyester filament passing at high speed, and penetrate into the bundles of the polyester filament, ensuring the uniformity of the oil film of the spinning oil, and meeting the application in the subsequent weaving.

[0003] At present, there is no mature spinning oil that can be used on FDY-WINGS spinning equipment in China. The existing spinning oil on the market is mainly conventional FDY oil, and conventional FDY oil is oiled at a yarn speed of 2000-3000m / min. When it is applied to FDY-WINGS spinning equipment, there are generally problems such as poor wetting and permeability at higher yarn speeds and instability of the emulsion at a higher oil concentration of more than 20%, which leads to uneven oil film, uneven network, oil splashing, oil mist, and low oiling efficiency of spinning oil in the polyester FDY-WINGS spinning process. In order to meet the spinning production requirements of FDY-WINGS spinning equipment at a high speed of 4000-5000m / min, the imported Dako 3013 oil is currently mainly used. However, the use of imported Dako 3013 oil will greatly increase the spinning production cost and there is an unstable supply chain problem. Therefore, it is necessary to develop a domestic FDY-WINGS spinning oil with fast wetting and permeability. Summary of the invention

[0004] In view of the defects of the prior art, the present invention provides a fast wetting and penetrating FDY-WINGS spinning oil, a preparation method and application thereof, which solves the technical problems of the prior art such as poor wetting and penetrating property of the spinning oil, uneven oil film, oil splashing, oil mist generation, uneven network and low oiling efficiency of the spinning oil.

[0019] In general, the above technical solution conceived by the present invention has the following advantages compared with the prior art:

[0020] Beneficial effects:

[0021] (1) The present invention provides a fast wetting and penetrating FDY-WINGS spinning oil agent based on the inherent characteristics of WINGS spinning equipment such as the oiling process and oiling speed. The spinning oil agent has good high-concentration emulsion stability and fast wetting and penetrating properties, is suitable for WINGS spinning equipment, has good spinnability, and can oil the fibers quickly and evenly. The uniform oil film layer on the fibers ensures that there are few broken ends during the processing, the winding and molding are good, and the rate of high-quality products is high, thus meeting user needs.

[0022] (2) The present invention provides a fast wetting and penetrating FDY-WINGS spinning oil. By adjusting the type and weight fraction of the wetting and penetrating agent added to the spinning oil, not only can the wetting and penetrating properties of the spinning oil be changed, but it can also be compounded with smoothing agents, emulsifiers, antistatic agents and other ingredients to synergistically improve the emulsification of the spinning oil, the high temperature stability of the emulsion and the long-term stability.

[0023] (3) In some embodiments of the present invention, a wetting and penetrating agent prepared by adding two ingredients, such as a wetting and penetrating agent prepared by combining sodium salt of dioctyl sulfonate succinate and isomeric decanol polyoxyethylene ether, or a wetting and penetrating agent prepared by combining sodium salt of dioctyl sulfonate succinate and polyether siloxane, can significantly improve the emulsification, high temperature stability and long-term use stability of the emulsion, and the wetting and penetrating properties of the spinning oil, reaching the level of the imported Dako 3013 oil.

[0024] (4) In the preferred embodiment of the present invention, a wetting and penetrating agent prepared by adding three components, such as sodium salt of dioctyl sulfonate succinate, isomeric decanol polyoxyethylene ether and polyether siloxane, is prepared by adding a wetting and penetrating agent. The prepared spinning oil has not only excellent emulsification and high concentration emulsion stability, but also has lower surface tension, shorter canvas sheet sedimentation time and higher wick height, which significantly improves the overall rapid wetting and penetrating property of the spinning oil emulsion. The emulsification, emulsion stability and wetting and penetrating property of the spinning oil are significantly better than the imported Dako 3013 oil of the comparative example 1. Specifically, the spinning oil prepared in the embodiment of the present invention has a minimum turbidity of 320, a minimum surface tension of 28.957 mN / m, a minimum canvas sheet sedimentation time of 1.91 s, and a maximum wick height of 95 mm, which are significantly better than the imported Dako 3013 oil.

[0025] The fast wetting and penetrating FDY-WINGS spinning oil provided by the present invention is suitable for the latest domestic WINGS spinning process, has good spinnability, is quickly and evenly oiled, and the fiber oiling layer ensures less breakage during processing, good winding and forming, and a high rate of superior products, thus meeting user needs.

[0063] The spinning oil of this comparative example is prepared in the same manner as in Example 1 except that no wetting and penetrating agent is added.

[0064] The product performance characterization and result analysis of the embodiments and control examples are as follows:

[0065] Table 1. Physical properties of FDY-WINGS spinning oils prepared in Examples 1 to 6 and Comparative Example 2:

[0066] project Quality Standards Appearance Light yellow transparent liquid Effective content (%) 90±1 pH value (10% aqueous solution) 7.0-8.0 Oil rotation viscosity (40℃, mPa.S) 50-55 20% oil emulsion rotational viscosity (40℃, mPa.S) 2-4

[0067] It can be seen from the physical property index data of the spinning oil in Table 1 that the spinning oil specially used for WINGS equipment prepared in Examples 1 to 6 and Control Example 2 is a uniform, stable light yellow transparent liquid; the pH of the oil emulsion is 7-8, which is weakly alkaline and has little corrosiveness to the oil emulsion delivery pipeline and the oil pump; the rotational viscosity of the oil is small, and the rotational viscosity of the oil emulsion is small, which is conducive to the rapid wetting and spreading of the oil on the fiber filaments.

[0068] (1) Emulsion stability

[0069] When WINGS spinning equipment is produced, FDY-WINGS spinning oil with a mass fraction of 20% is mostly transported to the small oil tank workshop for oiling through the oil mixing tank pipeline. Therefore, the present invention evaluates the emulsification and stability of the spinning oil by testing the turbidity change of the spinning oil emulsion with a mass fraction of 20%.

[0070] The emulsion turbidity test method is as follows: Use the TL2350 turbidity meter of Hach Company in the United States to test the emulsion turbidity of the spinning oil. First, prepare an oil emulsion with a mass fraction of 20%, then add about 30ml of the oil emulsion sample to the scale line of the test tube, then immediately cover the test tube with a lid and wipe the surface of the test tube clean. Place the test tube in the sample container rack of the turbidity meter so that the triangle on the test tube is aligned with the reference mark on the sample container rack. Press the lid to close it until you hear a click. Press the "Read" button, wait for the instrument to automatically read the sample, and record the turbidity reading displayed by the instrument.

[0071] The turbidity of the emulsion reflects the appearance of the emulsion. Generally, the turbidity of the oil emulsion is between 200-500. The smaller the turbidity of the emulsion, the better the emulsification of the oil, and the more blue and transparent the appearance of the oil emulsion. If the turbidity of the oil emulsion is greater than 1000, the appearance of the oil emulsion is milky white turbid liquid, and customers will think that the stability of the oil is poor and the oil emulsion is easy to corrupt. The turbidity of the emulsion fluctuates little under different conditions, indicating that the stability of the emulsion is good.

[0072] (2) Wetting and permeability

[0073] The surface tension test method is as follows: Use a surface tension meter K-100 to measure the surface tension of an oil emulsion with a mass fraction of 20%. Generally, the lower the surface tension of the oil emulsion, the better its wetting and penetration properties.

[0074] The canvas sheet settling time test method is as follows: Use a defatted standard canvas with a diameter of 20mm and a thickness of 2mm as a test piece, place it on the surface of a 20% oil emulsion at 40°C, record the time required for the canvas sheet to settle in the emulsion, and take the average value of 10 measurements. The shorter the canvas sheet settling time, the better the wetting and penetration of the oil emulsion.

[0075] The wick height test method is as follows: a polyester cloth strip with a length of 250 mm and a width of 10 mm is suspended upright with a clamp, and quickly placed in a 20% oil emulsion at 40°C, and the height of the oil emulsion rising to the cloth strip after 15 minutes is recorded. The greater the wick height, the better the wetting and penetration of the oil emulsion.

[0076] The dynamic contact angle test method is as follows: Use a fully automatic single fiber contact angle measuring instrument to test the dynamic contact angle change of a 20% oil emulsion on a polyester sheet. The smaller the contact angle, the better the wetting and spreading properties of the oil emulsion.

[0077] The test results are as follows:

[0078] Table 2. Emulsification and emulsion stability of spinning oil

[0079]

[0080]

[0081] Control Example 2 is a spinning oil without the addition of a wetting and penetrating agent. It can be seen from Control Example 1 and Control Example 2 in Table 2 that the turbidity of the ready-mixed control example 2 and the turbidity fluctuation of the oil emulsion are greater than those of Control Example 1, indicating that the emulsification, high temperature stability and long-term stability of the emulsion of Control Example 2 are worse than those of the imported Dako 3013 oil.

[0082] In Examples 1 to 6, 3 to 5 parts of wetting and penetrating agents are added to the control example 2, wherein Examples 1 and 2 are wetting and penetrating agents with a single component, Examples 3, 4, and 5 are wetting and penetrating agents with two components added, and Example 6 is a wetting and penetrating agent with three components added. Compared with the control example 2, the turbidity of Example 2 is less than that of Example 1 and less than that of the control example 2, and the turbidity change of Example 1 is less than that of the control example 2 and less than that of Example 2, indicating that the addition of wetting and penetrating agents will affect the emulsification of the oil, the high temperature stability and long-term stability of the emulsion, wherein the addition of 3 parts of sodium salt of dioctyl sulfonate succinate in Example 1 can enhance the emulsification of the spinning oil, the high temperature stability and long-term stability of the emulsion, and the increase in the weight of sodium salt of dioctyl sulfonate succinate in Example 2 will make the high temperature stability and long-term stability of the oil emulsion worse, and the emulsification of the oil is significantly improved.

[0083] Compared with Example 2, in Example 3, Example 4 and Example 5, when the amount of wetting and penetrating agent added is the same, the wetting and penetrating agent compounded with sodium salt of dioctyl sulfonate succinate and polyether siloxane is added in Example 3, and the wetting and penetrating agent compounded with sodium salt of dioctyl sulfonate succinate and isomeric decanol polyoxyethylene ether is added in Example 5, can enhance the high temperature stability and long-term stability of the spinning oil emulsion, and are better than Example 2 in which only sodium salt of dioctyl sulfonate succinate is added as the wetting and penetrating agent. In Example 4, sodium salt of dioctyl sulfonate succinate and lauryl dimethyl silicone oil are added to make the emulsification of the oil, the high temperature stability of the emulsion and the long-term stability lower than that of Example 2. By comparing Examples 3 and 5 with Comparative Example 1, it can be seen that the emulsification of Examples 3 and 5 is slightly worse than that of the imported Dako 3013 oil, and the high temperature stability and long-term stability of the spinning oil emulsion are better than those of the imported Dako 3013 oil.

[0084] In Example 6, a wetting and penetrating agent compounded with dioctyl sulfonate succinate sodium salt, isomeric decanol polyoxyethylene ether and polyether siloxane is added, and its current turbidity is 320, which is less than the imported Dako 3013 oil in Control Example 1. In addition, the turbidity change of the spinning oil after being placed at a high temperature of 50°C for 3 hours and the turbidity change after being placed at room temperature for one week are both less than the imported Dako 3013 oil. It is shown that the addition of a wetting and penetrating agent compounded with dioctyl sulfonate succinate sodium salt, isomeric decanol polyoxyethylene ether and polyether siloxane in the spinning oil can significantly enhance the emulsification, high temperature stability and long-term stability of the spinning oil, and is even better than the imported Dako 3013 oil.

[0086]

[0087] As can be seen from Table 3, Examples 1 and 2 and Comparative Example 2 clearly show that the addition of sodium dioctyl sulfosuccinate in Examples 1 and 2 can optimize the surface tension of the oil, the settling time of the canvas sheet and the height of the wick, and improve the wetting and permeability of the spinning oil. In addition, the wetting and permeability of the oil will be further improved by increasing the weight fraction of the wetting and permeating agent in Example 2. However, the wetting and permeability of Examples 1 and 2 is lower than that of the imported Dako 3013 oil in Comparative Example 1, indicating that the addition of only a single component of the wetting and permeating agent in the examples and the increase in its weight fraction have limited effect on the improvement of the wetting and permeability of the oil.

[0088] Compared with Example 2, when the amount of wetting and penetrating agent added is the same, Example 3 adds a wetting and penetrating agent prepared by compounding dioctyl sulfonate sodium salt and polyether siloxane, and Example 5 adds a wetting and penetrating agent prepared by compounding dioctyl sulfonate sodium salt and isomeric decanol polyoxyethylene ether, which significantly improves the wetting and penetrating properties of the spinning oil, reaching the level of the imported Dako 3013 oil. In Example 4, a wetting and penetrating agent compounded by dioctyl sulfonate sodium salt and lauryl dimethyl silicone oil is added, which makes the canvas sheet sedimentation time and wick height of the spinning oil worse.

[0089] Example 6 adds a wetting and penetrating agent prepared by combining sodium salt of dioctyl sulfonate succinate, isomeric decanol polyoxyethylene ether and polyether siloxane, so that the oil has a lower surface tension, a shorter canvas sheet sedimentation time and a higher wick height, which significantly improves the overall rapid wetting and penetrability of the spinning oil emulsion, and is even better than the imported Dako 3013 oil in Control Example 1.

[0090] The dynamic contact angles of the spinning oil emulsions of Examples 1 to 6 and Comparative Examples 1 and 2 on the polyester sheet are shown in FIG. Figure 1 As shown, it can be seen that the dynamic contact angle of Example 6 changes the fastest and reaches the minimum value after 100ms, which is better than the imported Dako 3013 oil agent of Control Example 1, indicating that the dynamic wetting and spreading property of Example 6 of the present invention is the best, which is beneficial to the rapid wetting and spreading of the oil emulsion at the oil nozzle of the WINGS spinning process equipment, and is beneficial to uniform oiling and rapid adhesion to the fiber filaments to form a uniform oil film, thus meeting customer needs.

[0091] It will be easily understood by those skilled in the art that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
