Description

Technical Field

[0001] The present invention belongs to the technical field of spinning oils, and more specifically, relates to an oil for T8 composite fibers, and its preparation and application. Background Art

[0002] T8 fiber is made by composite spinning of PET and PBT, and has a parallel structure. The unique microstructure of T8 fiber, which is like a spiral spring, gives it extreme elasticity, a cotton feel (from the curled fiber shape), moisture absorption and quick drying (due to the large number of micro spaces on the single-layer fabric, the moisture in the fabric can diffuse and evaporate faster). However, the smoothness and anti-static properties of T8 fiber itself are deviated. The unique fiber structure of T8 fiber requires that the oil used in the texturizing process have excellent smoothness, anti-static and permeability. Currently, the texturizing oil used for T8 fiber on the market is mostly conventional DTY oil. The smoothness, permeability and anti-static properties of conventional DTY oil cannot meet the processing requirements of T8 fiber, and therefore often cause weaving problems for downstream customers, such as high static electricity during warping and bobbin drop during unwinding. Summary of the Invention

[0018] According to another aspect of the present invention, there is provided an application of the oil agent for spinning processing of T8 fibers.

[0019] In general, the above technical solutions conceived by the present invention have the following beneficial effects compared with the prior art:

[0020] (1) Conventional DTY oil lubrication system is mainly based on mineral oil. The present invention uses a lubrication system mainly based on mineral oil, synthetic ester and long carbon chain mixed polyether, which greatly improves the basic lubrication performance of the product and reduces static electricity generated by friction in downstream weaving.

[0021] (2) Conventional DTY texturizing agents usually add antistatic agents such as phosphates and sulfuric acid to improve the antistatic properties of the product. The addition of antistatic agents will increase the water absorption of the fiber, and excessive water absorption of the fiber will lead to poor smoothness, especially the friction between the fiber and the metal. The present invention achieves the purpose of improving smoothness by adding smoothing agents such as alkyl sulfonates, alkyl sulfate esters and fatty acid salts to form competitive adsorption with phosphate antistatic agents on the metal surface.

[0022] (3) Conventional T8 fiber texturizing oils use wetting and penetrating agents that are mostly low-viscosity dimethyl silicone oils, whose oiling performance often cannot meet customer needs. The present invention significantly improves the wetting and penetrating performance of the product by combining modified fluorosilicone oil with lower surface tension and polyether siloxane wetting and penetrating agents. DETAILED DESCRIPTION

[0027] In some embodiments, the polyether silicone includes but is not limited to polyethylene glycol / polypropylene glycol-1,2 dimethyl siloxane (EO number 5-15, PO number 5-15, 1,2 dimethyl siloxane molecular weight of 2000-15000), lauryl polyethylene glycol / polypropylene glycol-dimethyl siloxane (EO number 5-15, PO number 5-15, dimethyl siloxane molecular weight of 2000-15000), etc., and the slash “ / ” means a mixture.

[0028] In some embodiments, the mineral oil is one or more of 5# industrial-grade white oil, 10# industrial-grade white oil, or 15# industrial-grade white oil. The synthetic ester is a C12-18 fatty acid isooctyl ester, including but not limited to one or more of isooctyl stearate, isooctyl oleate, and isooctyl cocoate. The long-chain mixed polyether is a C14-18 fatty alcohol polyoxyethylene / polyoxypropylene mixed polyether, including but not limited to one or more of oleyl alcohol polyoxyethylene / polyoxypropylene mixed polyether, C14-16 fatty alcohol polyoxyethylene / polyoxypropylene mixed polyether, and C16-18 fatty alcohol polyoxyethylene / polyoxypropylene mixed polyether. In these long-chain mixed polyethers, the number of EOs of the polyoxyethylene is 5-10, and the number of POs of the polyoxypropylene is 5-10. The slash " / " indicates a mixture.

[0029] In some embodiments, the emulsifier is a C12-14 fatty alcohol polyoxyethylene ether with an EO number of 2-6, including but not limited to one or more of C12-14 fatty alcohol polyoxyethylene (2) ether and C12-14 fatty alcohol polyoxyethylene (3) ether.

[0030] In some embodiments, the detergent is 6501 (coconut oil fatty acid diethanolamine); the anti-splash agent is one or more of polyisobutylene with a molecular weight of 100,000-5,000,000 and ethylene propylene copolymer with a molecular weight of 20,000-200,000.

[0031] In some embodiments, the antistatic agent is one or more of APEK (C12-14 fatty alcohol polyoxyethylene (3) ether phosphate salt) and AES (C12-14 fatty alcohol polyoxyethylene (3) ether sulfate salt), and "(3)" means that the EO number is 3.

[0032] According to another aspect of the present invention, a method for preparing the oil is provided, comprising the following steps: mixing an emulsifier, a detergent, an antistatic agent, and a smoothing agent according to the above-mentioned mass ratio and stirring for 30 minutes to obtain compound A; and then mixing mineral oil, synthetic ester, a long carbon chain mixed polyether, an anti-splash agent, a wetting and penetrating agent with compound A and stirring to obtain the oil.

[0033] Conventional fiber such as PET polyester fiber is a single-component fiber, and T8 fiber is a two-component fiber formed by PET and PBT composite spinning, and the spinning oil of two-component fiber is much higher than the spinning oil of single-component fiber in terms of antistatic property, so conventional single-component fiber spinning oil on the market can not meet the spinning requirements of T8 fiber of the present invention. On the one hand, the present invention is based on the lubrication system of mineral oil, synthetic ester and long carbon chain mixed polyether (EO / PO), and the lubrication performance on different surfaces is complementary by the difference in polarity of each raw material. Compared with the original lubrication system based on mineral oil system, excellent smoothness can be provided for T8 fiber, and good smoothness can reduce the generation of static electricity. On the other hand, in order to further promote the lubrication performance and antistatic performance of product, the present invention is by adding smoothing aids such as appropriate alkyl sulfonate, alkyl sulfate ester salt and fatty acid salt, and it is good to form competitive adsorption with phosphate antistatic agent on metal surface, thereby reducing the phenomenon that smoothness deteriorates because of fiber water absorption, and smoothing aid itself also has antistatic performance, therefore the smoothness performance and antistatic performance of product can be greatly improved. Furthermore, compared with conventional dimethyl silicone oil-based wetting and penetrating agents, the present invention can reduce the surface tension of the oil agent to the greatest extent by using a high-efficiency wetting and penetrating system composed of modified fluorosilicone oil and polyether siloxane and other wetting and penetrating agents. The lower surface tension can greatly increase the oiling rate of T8 fiber, thereby solving the problem of difficulty in oiling for downstream customers. The increase in the oiling rate can also enhance the antistatic properties of the fiber.

[0034] Therefore, the present invention has developed a spin finish specifically for T8 fibers by modifying the lubricating system composition, adding a smoothing agent, and using a high-efficiency wetting and penetrating agent. Compared to conventional spin finishes, the present spin finish has a higher oil uptake rate, better smoothness, and superior antistatic properties. These improvements in smoothness and wetting and penetrating properties indirectly enhance the spin finish's antistatic properties, meeting the spinning requirements of T8 bicomponent fibers.

[0060]

[0061] As shown in Table 1, a comparison of the test results of Examples 1-3 with Control Experiment 1 shows that the oiling performance, antistatic performance, and smoothing performance of the oils of the examples are superior to those of conventional texturizing oils.
