Description

Technical Field

[0001] The invention relates to the technical field of nylon ultra-high-speed spinning oil preparation, and in particular to a preparation process and application of high-permeability, high-temperature-resistant nylon ultra-high-speed spinning oil. Background Art

[0002] The ultra-high-speed spinning process of nylon requires the spinning speed to be run at an extremely high level, usually above 4000 m / min, which is nearly 1000 m / min higher than the traditional spinning process. This high-speed spinning process places more stringent requirements on the performance of the oil. The oil needs to maintain stable lubricity, antistatic properties and smoothness under high temperature and high-speed conditions to ensure the smooth progress of the spinning process and the excellent quality of the final product. The oil needs to be able to effectively reduce the friction coefficient between fibers so that the fibers can pass through each process smoothly during the spinning process. However, the existing ultra-high-speed spinning oil for nylon has poor permeability and cannot quickly penetrate into the fiber, reducing the smoothness and glossiness of the fiber.

[0003] The defects of existing nylon ultra-high speed spinning oil are:

[0004] 1. Patent document CN115896982B discloses a preparation process of an environmentally friendly spinning oil, "including: step 1, reacting vegetable oil and ethanol through transesterification to generate vegetable oil monoester, and using hydrogen peroxide to convert the double bonds in the vegetable oil monoester into saturated epoxy bonds; step 2, adding p-aminobenzenesulfonamide to the epoxidized vegetable oil ester, keeping the reaction temperature to react, and after the reaction is completed, decompressing and filtering to collect the product; step 3, adding fatty acids to the product to open the epoxy bonds to form a vegetable oil monoester containing hydroxyl groups, and then esterifying the generated hydroxyl groups with anhydride to generate a polyester vegetable oil ester; step 4, adding a sizing agent, an emulsifier and an antistatic agent to a reaction vessel, heating and stirring evenly, then adding vegetable oil, stirring, and then adding other additives, stirring evenly, cooling, filtering to obtain the product", but the existing nylon ultra-high-speed spinning oil has a short oxidation induction time and poor oxidation performance. The spinning oil is easy to deteriorate in long-term use;

[0005] 2. Patent document CN111378134A discloses a preparation process of an antistatic agent for chemical fiber spinning oil, "including the following steps: step 1, adding epoxy modified silicone oil into a reactor for heating to 100-250°C and keeping warm for 1-4 hours; step 2, preheating polyol to 70-120°C, then adding it into the reactor and mixing it with epoxy modified silicone oil for sufficient reaction, stirring the mixed system in the reactor, adjusting the temperature in the reactor to 80-220°C, and the reaction time is 4-6 hours, an antistatic agent for chemical fiber spinning oil is obtained. In the process of preparing the antistatic agent, the epoxy group on the modified silicone oil reacts with the hydroxyl group of the polyol, and the alcohol hydroxyl group can open the epoxy group to react to form a highly cross-linked polyether structure, which has a certain antistatic property. The antistatic agent is combined with the silicone oil component to solve the problem of poor compatibility between the two in the oil. However, the existing nylon ultra-high-speed spinning oil has poor permeability and cannot quickly penetrate into the fiber, reducing the smoothness and glossiness of the fiber;

[0006] 3. Patent document CN112281261A discloses a high-speed spinning oil with strong permeability and its preparation process. "The ultrafine filament spinning oil is composed of the following raw materials in parts by weight: 20-30 parts of vegetable oil, 1-4 parts of mineral oil, 5-8 parts of fatty alcohol ester, 5-8 parts of polyol ester, 2-5 parts of potassium salt of vinyl ether phosphate, 2-4 parts of antistatic agent, 11-14 parts of wetting agent, 3-5 parts of anti-splashing agent, 3-5 parts of polyether polyol ester, 6-10 parts of emulsifier, 1-5 parts of coconut oil glycol amide, 5-10 parts of penetrant, 1-3 parts of defoaming agent, 5-7 parts of sodium carbonate, 20-30 parts of deionized water. After the high-permeability high-speed spinning processing oil agent of the present invention is applied, the wetting permeability of the high-speed spinning oil agent can be optimized, the oil agent molecules can quickly adhere to and diffuse on the fiber, so that the oil agent is evenly attached to the spinning, and the smoothing effect, antistatic effect and bundling effect of the high-speed spinning oil agent can be normally exerted, avoiding the phenomenon of fiber fluffy, spear head, broken end, winding Rota, adhesion equipment, etc., but the existing nylon ultra-high-speed spinning oil has low stability and low heat resistance stability.

[0065] The invention discloses an application of a high-permeability, high-temperature-resistant nylon ultra-high-speed spinning oil, including application in a spinning process and application in a post-processing process. The application in the spinning process is to evenly apply the prepared high-permeability, high-temperature-resistant spinning oil on the fiber during the ultra-high-speed spinning process of nylon, which helps to reduce the friction coefficient between the fibers and improve the smoothness and bundling of the fibers, thereby ensuring the smooth progress of the spinning process. The high-temperature resistance of the spinning oil helps to prevent the fibers from being deformed or damaged at high temperatures, thereby ensuring the quality of the finished fibers. The application in the post-processing process is to apply an appropriate amount of high-permeability, high-temperature-resistant spinning oil in the stretching and elasticizing processes during the post-processing of nylon fibers, thereby helping to further improve the physical properties of the fibers, such as strength and wear resistance. At the same time, the antistatic property of the spinning oil helps to prevent static electricity accumulation in the fibers during the processing process, thereby avoiding the failures caused by this.
