Description

Technical Field

[0001] This invention relates to the field of textile oiling technology, and in particular to a viscose staple fiber spinning oiling agent, its preparation method, and its application. Background Technology

[0002] Viscose staple fiber is an important type of regenerated cellulose fiber, widely used in spinning, weaving, and nonwoven fabrics. In the production and subsequent textile processing of viscose staple fiber, spinning oil is one of the key auxiliaries affecting fiber processing performance and product quality. For viscose staple fiber, spinning oil not only needs to improve the surface lubrication of the fiber, but also needs to reasonably adjust the dynamic and static friction coefficients between fibers and between fibers and processing components to meet the requirements of different processing steps. A suitable spinning oil can improve fiber cohesion and spinnability, reduce processing resistance, improve the tow's running state, thereby enhancing the continuity and stability of the production process, and giving the fiber a smooth, fluffy, and soft hand feel.

[0003] However, existing viscose staple fiber spinning oils still have certain shortcomings in practical applications. For example, some spinning oils do not provide ideal overall regulation of fiber smoothness, cohesion, and antistatic properties, leading to problems such as fiber bundle divergence, increased fuzz, fiber breakage, roller entanglement, fly waste, and static electricity accumulation during spinning, yarn spinning, and weaving. This not only affects the smooth operation of the production process and reduces equipment efficiency but also adversely impacts the stability of product quality.

[0004] Therefore, providing a spinning oil that can improve the smoothness, cohesion, and antistatic properties of viscose staple fibers while reducing processing defects is a technical problem that urgently needs to be solved in this field. Summary of the Invention

[0005] To address the aforementioned problems in existing technologies, this invention provides a viscose staple fiber spinning oil, its preparation method, and its application. The viscose staple fiber spinning oil provided by this invention possesses excellent smoothness, cohesion, and antistatic properties, improving fiber spinnability and processing stability, while also exhibiting low toxicity and environmental friendliness.

[0006] The technical solution of the present invention is as follows: The first aspect of this invention protects a viscose staple fiber spinning oil, comprising the following components in parts by weight: 30-70 parts of component A and 70-30 parts of component B; Component A includes C8-C20 alkoxy alcohol polyoxyethylene ether phosphate potassium salt, isomeric polyol polyoxyethylene ether, alkyl betaine, stearate polyoxyethylene ether, castor oil polyoxyethylene ether, C10-16 alcohol alkoxylate, and water. Component B includes polyethylene glycol dioleate, polyethylene glycol monooleate, polyoxyethylene stearate, polyoxyethylene laurate, dodecyl / octadecylamine polyoxyethylene ether, fatty alcohol polyoxyethylene ether, base oil, and oleic acid.

[0007] Preferably, based on the total amount of the viscose staple fiber spinning oil, component A comprises the following raw materials in parts by weight: 6-14 parts of potassium salt of C8-C20 alkoxy alcohol polyoxyethylene ether phosphate, 2-4 parts of isomeric polyol polyoxyethylene ether, 3-7 parts of alkyl betaine, 6-14 parts of polyoxyethylene stearate, 7-17 parts of castor oil polyoxyethylene ether, 2-4 parts of C10-16 alcohol alkoxylate, and the balance being water.

[0008] Preferably, based on the total amount of the viscose staple fiber spinning oil, component B comprises the following raw materials in parts by weight: 5-11 parts polyethylene glycol dioleate, 6-14 parts polyethylene glycol monooleate, 3-7 parts polyoxyethylene stearate, 6-14 parts polyoxyethylene laurate, 4-10 parts dodecyl / octadecylamine polyoxyethylene ether, 3-7 parts fatty alcohol polyoxyethylene ether, 2-4 parts base oil, and 1-3 parts oleic acid.

[0009] Preferably, the C8-C20 alkoxy alcohol polyoxyethylene ether phosphate potassium salt is a mixture obtained by mixing C12-C14 alcohol polyoxyethylene ether phosphate potassium salt and coconut oil alcohol phosphate potassium salt in a mass ratio of 1:1.

[0010] Preferably, the base oil is industrial white oil.

[0011] Preferably, the dodecyl / octadecylamine polyoxyethylene ether is a mixture of dodecylamine polyoxyethylene ether and octadecylamine polyoxyethylene ether at a mass ratio of 1:12.

[0012] The second aspect of this invention protects a method for preparing the viscose staple fiber spinning oil described in the first aspect, comprising the following steps: S1. According to the formula, add C8-C20 alkoxy alcohol polyoxyethylene ether phosphate potassium salt, isomeric polyol polyoxyethylene ether, alkyl betaine, stearic acid polyoxyethylene ether, castor oil polyoxyethylene ether, C10-16 alcohol alkoxylate, and water into the reaction vessel, heat, stir evenly, and cool to room temperature to obtain component A. S2. According to the formula, add polyethylene glycol dioleate, polyethylene glycol monooleate, polyoxyethylene stearate, polyoxyethylene laurate, dodecyl / octadecylamine polyoxyethylene ether, fatty alcohol polyoxyethylene ether, base oil, and oleic acid into another reaction vessel and stir evenly to obtain component B. S3. Mix component A and component B and stir evenly to obtain viscose staple fiber spinning oil.

[0013] Preferably, in step S1, the heating temperature is 70–80°C.

[0014] The third aspect of this invention protects the application of a viscose staple fiber spinning oil in the viscose staple fiber spinning production process, wherein the viscose staple fiber spinning oil is the viscose staple fiber spinning oil described in the first aspect, or the viscose staple fiber spinning oil prepared by the preparation method described in the second aspect.

[0015] The beneficial technical effects of this invention are as follows: The viscose staple fiber spinning oil of this invention is a compound of component A and component B. Component A mainly provides antistatic properties, moderate hygroscopicity, and cohesion regulation, which can reduce fiber surface resistance, promote the discharge of surface charge accumulation, and improve the cohesion between fibers. Component B mainly provides smoothness and softness, and can adjust the dynamic and static friction coefficients between fibers and between fibers and processing parts, so that the fibers have better smoothness and bundling properties during spinning, yarn spinning, and subsequent processing. In other words, the viscose staple fiber spinning oil of this invention can improve the smoothness, cohesion, and antistatic properties of viscose staple fibers, and reduce defects such as fuzz, breakage, roller wrapping, fly waste, and static electricity caused by insufficient smoothness, poor cohesion, fiber bundle divergence, and static electricity accumulation, thereby improving the spinnability of the fibers and ensuring continuous and stable production processes.

[0016] Furthermore, the two-component viscose staple fiber spinning oil of this invention does not contain low-boiling-point volatile components such as ethanol, nonylphenol polyoxyethylene ether, glycerol castor oil ester, glycerol fatty acid ester, sperm whale oil sodium sulfate, and sodium lauryl sulfate, etc. Therefore, it has good low toxicity, environmental friendliness and biofriendliness, which can effectively reduce VOC emissions and reduce the adverse impact on the production environment and ecological environment. Detailed Implementation

[0017] The present invention will now be described in detail with reference to the embodiments.

[0018] A viscose staple fiber spinning oil comprises the following components in parts by weight: 30-70 parts of component A and 70-30 parts of component B; Component A includes C8-C20 alkoxy alcohol polyoxyethylene ether phosphate potassium salt, isomeric polyol polyoxyethylene ether, alkyl betaine, stearate polyoxyethylene ether, castor oil polyoxyethylene ether, C10-16 alcohol alkoxylate, and water. Component B includes polyethylene glycol dioleate, polyethylene glycol monooleate, polyoxyethylene stearate, polyoxyethylene laurate, dodecyl / octadecylamine polyoxyethylene ether, fatty alcohol polyoxyethylene ether, base oil, and oleic acid.

[0019] This invention relates to a viscose staple fiber spinning oil, composed of a compound of component A and component B. Component A consists of anionic antistatic agents and nonionic emulsifiers, which can adjust the frictional properties of the fibers and improve the cohesion between fibers. Simultaneously, it moderately absorbs moisture, facilitating the discharge of accumulated charges on the fiber surface, thereby reducing surface resistance and eliminating static electricity. Component B consists of nonionic smoothing agents, emulsifiers, and softeners, primarily used to give the fibers good smoothness and softness. After passing through the smoothing agent, friction occurs between the sliding hydrophobic groups, resulting in a softening effect and improved spinnability.

[0044] A method for preparing a viscose staple fiber spinning oil is basically the same as that in Example 1, except that the heating temperature in step S1 is 80°C.

[0045] Test case Test Example 1 Commercially available similar products were selected as control standards. The control standards and the spinning oils prepared in Examples 1-5 were applied to the surface of viscose filaments to control the fiber oil content to 0.20%. Under the same test conditions, the dynamic friction coefficient and static friction coefficient of each sample were measured using a μ-Meter friction coefficient meter, with the dynamic friction coefficient test speed being 100 m / min.

[0046] Table 1: Test results of friction properties of different spinning oils

[0047] As shown in Table 1, under the same oil content, the spinning oil prepared in the embodiments of the present invention exhibits superior frictional properties compared to the control. Specifically, the dynamic frictional properties of the embodiments of the present invention are superior, effectively reducing the frictional resistance of the fibers during movement and improving fiber smoothness. Simultaneously, the static frictional properties of the embodiments are within a suitable range, which is beneficial for maintaining the necessary cohesion between fibers. The viscose staple fiber spinning oil of the present invention can effectively balance smoothness and cohesion, thereby helping to reduce problems such as fuzzing, breakage, and fly waste in subsequent fiber processing, and improving the stability of the processing.

[0048] Test Example 2 Viscose staple fiber was used as the test object, and commercially available similar products were selected as the control. The control and the spinning oil prepared in Examples 1 to 5 were applied to the fiber surface by spraying oil, and the oiling rate (OPU) was controlled to be 0.2%. Under the temperature and humidity conditions shown in Table 2, the resistivity of the oiled fiber was tested. Each sample was tested in parallel three times, and the average value was taken. The results are shown in Table 2.

[0049] Table 2: Specific resistance test results of different spinning oils

[0050] As shown in Table 2, the resistivity of viscose staple fibers treated with the spinning oil prepared in the embodiments of the present invention is significantly lower than that of the control product, indicating that the spinning oil of the present invention has superior antistatic properties and can effectively reduce static electricity accumulation on the fiber surface. In other words, the viscose staple fiber spinning oil of the present invention can improve the static conductivity of the fiber, thereby reducing problems such as fuzz, fly waste, and roller entanglement caused by static electricity during processing, and improving the stability of the processing and the quality of the finished product.

[0051] Based on the above, it can be seen that from Examples 1 to 5, as the content of component A gradually increases and the content of component B gradually decreases, the dynamic friction of the oil remains at a low range, while the static friction coefficient gradually increases. This indicates that the oil can gradually improve the cohesion between fibers while maintaining good lubricity. Simultaneously, since component A contains a large amount of antistatic components, the antistatic properties of the oil also increase with the increase of the proportion of component A. Therefore, by adjusting the ratio of components A and B, the lubricity, cohesion, and antistatic properties of the oil can be effectively improved, thereby further enhancing the processing stability and spinnability of viscose staple fibers.

[0052] The above description is merely a preferred embodiment of the present invention, and the present invention is not limited to the above embodiments. It is understood that other improvements and variations that are directly derived or conceived by those skilled in the art without departing from the spirit and concept of the present invention should be considered to be included within the protection scope of the present invention.
