Description
Technical Field
The invention relates to the technical field of polyester preparation, in particular to a polyester FDY oiling agent and a preparation method thereof.
Background
Terylene is a synthetic fiber variety with the largest capacity and the widest application in the world. In the chemical fiber industrial yield of China, the terylene yield accounts for more than 80 percent of the total yield. The terylene is fiber prepared by using Purified Terephthalic Acid (PTA) or dimethyl terephthalate (DMT) and ethylene glycol (MEG) as raw materials, performing esterification or ester exchange, performing polycondensation reaction to prepare fiber-forming high polymer polyethylene terephthalate (PET), and then spinning and post-treating the PET. The Fully Drawn Yarn (FDY) is one of main products in the terylene industry in China, the preparation method of the FDY is a spinning and drawing one-step method combining high-speed spinning (spinning speed 2600-3500 m/min) and ultrahigh-speed drawing and winding (winding speed 5100-5500 m/min), and compared with the traditional process combining low-speed spinning and high-speed drawing and winding, the method has the advantages of low cost, stable product quality and the like.
It is known that synthetic fibers do not have a natural gum or oil film, have poor moisture absorption, and are non-conductive, so that static electricity is easily generated due to continuous friction during spinning, and thus it is necessary to use an auxiliary agent for preventing or eliminating static electricity accumulation, and to impart softness, smoothness, and the like to the fibers so that the fibers can smoothly pass through a subsequent process, and such an auxiliary agent is collectively called a fiber spinning finish. Generally, an excellent fiber spin finish should have the following characteristics: smooth, antistatic, and has bundling or cohesion effects; the thermal stability is good, and the volatility is low; no corrosion to metal; the washability is good, and the color of the fiber is not influenced; no odor and irritation, no delamination and no putrefaction and deterioration under the specified storage condition; convenient preparation and use, easily obtained raw materials and proper cost.
In the production process of Fully Drawn Yarn (FDY), the polyester FDY oiling agent is an essential auxiliary agent in the spinning process of a polyester spinning and drawing one-step method, and can ensure that fibers have good performances of smoothness, bundling, static resistance and the like, so that spinning can be smoothly carried out, and spun filaments meet the requirements of subsequent processing. However, the quality of the domestic chemical fiber oil agent is unstable or the technical barriers such as large-scale industrial production are difficult to realize for a long time, and the quality and the yield of the domestic chemical fiber oil agent can not meet the production requirements of chemical fiber enterprises in China. Compared with the FDY produced by high-speed spinning in the terylene industry of China, the FDY has the advantages of vigorous productivity and obvious inconsistency, and instead, a considerable amount of oiling agents and key additives which are imported from foreign countries cost tens of millions of dollars are needed to meet the production requirements of chemical fiber enterprises every year. Nowadays, the market share of domestic brand spinning oil agents is still less than 25%, and the autonomous industrial preparation of high-performance terylene high-speed spinning FDY oil agents is still an unsolved neck problem. In recent years, some research and development work is carried out on polyester high-speed spinning FDY oil by domestic related oil manufacturing enterprises, but the overall quality of the FDY oil is still different from that of oil in industrially developed countries, and the FDY oil is mainly represented as follows:
firstly, the current domestic terylene FDY oil agent mainly takes an emulsion type as a main part, the problems of unstable emulsion and the like often occur in use, the phenomena of layering and emulsion breaking often occur, and the oiling uniformity and the control on the oiling dosage are influenced. In addition, the polyester FDY oil applied to the emulsion generally has the problem of easy decay, so a certain proportion of preservative is usually added into the oil, but the preservative is easy to volatilize at a hot roller, and the environmental safety and the human health are influenced. Secondly, because the emulsion usually contains more than 80 percent of water, the water is volatile under the conditions of hot roller drafting extrusion and high-temperature heating, so that an oil film is broken, and the product quality problems of poor cohesion of tows among monofilaments, easy slippage of the tows during high-speed running of a shifting fork and a spindle shaft, obvious spiral veins of the appearance of a produced spinning cake package and the like are caused. In addition, the heat at the position of the hot roller can be taken away by the evaporation of the water, so that the production energy consumption is increased, the energy conservation and emission reduction are not facilitated, and the pressure of chemical fiber enterprises for realizing the double-carbon target is increased;
secondly, because the polyester FDY spinning process has high speed and large friction, static electricity is easily generated to cause broken filaments and broken ends, and therefore, the polyester FDY oiling agent has good antistatic property. However, the antistatic performance of the existing spinning oil in China is poor, and the improvement on the smoothness and the bundling property of the fiber yarns is not ideal. Based on the limitation of cost and upstream enterprise product types, the domestic traditional spinning oil agent mainly adopts single phosphate ester or is matched with beta-alkyl sulfonate to be used as an antistatic agent, so that the oil agent can only be ensured to have good antistatic property under higher humidity, the antistatic property is greatly reduced under the condition of lower humidity, and the use of the fiber oil agent is greatly limited, for example, the phenomena of frequent winding and breakage due to poor antistatic effect are easy to occur in the dry north of China or in dry seasons;
thirdly, the oil film formed on the surface of the fiber is easy to break at high speed, high temperature and certain pressure, so that the friction characteristic of the fiber is changed, the friction force of the fiber is increased, and broken filaments, broken ends and the like are caused, therefore, the oil agent is required to have higher oil film strength. However, the existing spinning oil in China mainly adopts mineral oil, natural oil, synthetic oil and the like as a smoothing agent, and the formed oil film has low strength and poor heat resistance and is easy to smoke and cause coking.

On the basis, the composite smoothing agent is added with a very small amount of organogelators, particularly low-molecular-weight organogelators, the organogelators are self-assembled in the composite smoothing agent by utilizing non-covalent interactions among molecules such as hydrogen bonds, van der Waals forces, coordination bonds, pi-pi stacking action and the like to form a physically-crosslinked three-dimensional grid structure, and the oil film strength formed by the composite smoothing agent is improved by permeating the three-dimensional grid structure of the composite smoothing agent.

In addition, the strong electropositivity of the secondary amino group on the chitosan molecule modified by maleic anhydride can penetrate the electronegative cell membrane and carboxyl group of the bacteria and Ca in the bacteria cells 2+ 、Mg 2+ The chelation of the metal ions (enzyme catalyst in the process of cell metabolism) can also play the role of bacteriostasis and sterilization.
It has been clear to those skilled in the art from many years of research that the antistatic principle of oil solutions is as follows: hydrophobic groups in the oil agent are adsorbed on the surface of the fiber, and hydrophilic groups tend to one side of air to form a hydrophilic film, so that the friction coefficient of the terylene is reduced, and the terylene is difficult to generate static electricity; meanwhile, the hydrophilic film can absorb moisture, such as water vapor in the air to form a moisture-conducting film, and the moisture-conducting film transfers the generated static electricity to the atmosphere to play an antistatic role. Generally, the antistatic effect of an antistatic agent is related to the effect of a continuous moisture-conductive film that it is capable of forming on the surface of fibers. When the antistatic agent enters the fiber or cannot be uniformly distributed on the surface of the fiber due to insufficient use amount and the like, a continuous moisture-conducting film cannot be formed on the surface of the fiber, and at the moment, the antistatic effect is obviously weakened. Based on this, a series of moisture-absorbing antistatic agents have been developed, such as deliquescent inorganic salts such as Licl and Kcl, and antistatic effects have been achieved by utilizing the moisture absorption of such inorganic salts. However, in an environment with low air humidity, the moisture-absorbing antistatic agent is difficult to absorb enough moisture, and other types of antistatic agents are also difficult to form a continuous moisture-transmitting film on the fiber surface, and in this case, the antistatic effect of the oil agent is greatly reduced.
In the antistatic agent, a proper amount of nonionic antistatic agent and anionic antistatic agent are added, so that the nonionic antistatic agent and the anionic antistatic agent are adsorbed on the surface of a fiber, and meanwhile, a hydrophilic group tends to air to form a hydrophilic film.
Meanwhile, the antistatic auxiliary agent can realize the functions of slowly releasing the nano metal oxide, the modified chitosan and the nano cellulose when in use, so that the sizing performance of the oil agent is not influenced, the oil agent can quickly and uniformly form an oil film on the surface of the fiber, the wear resistance of the oil agent can be improved by utilizing the nano metal oxide released by the antistatic auxiliary agent, and the strength of the oil film can be improved by utilizing the modified chitosan and the nano cellulose.
Further, the preparation method of the antistatic auxiliary agent comprises the following steps:
s1, dissolving 1-3 parts by weight of nano-cellulose in a proper amount of deionized water, continuously stirring until the nano-cellulose is completely dissolved in the water, then adding 0.1-0.2 part by weight of an initiator, and fully stirring uniformly for later use;

Further, the penetrating agent comprises 20-30 parts by weight of succinic acid, 30-40 parts by weight of squalane, 30-50 parts by weight of solvent oil and 30-40 parts by weight of white oil.
Furthermore, the antioxidant comprises 30-50 parts by weight of hydroxylated or vulcanized vegetable oil and 20-25 parts by weight of phosphite ester, the antioxidant effect of the oil agent can be improved by adopting the vegetable oil and the phosphite ester to replace the traditional antioxidant, and meanwhile, the vegetable oil can react with metal on the surface of the friction part to form a protective film, so that the friction resistance between equipment and the fiber surface is reduced, and the abrasion is reduced.
In addition, the application also provides a preparation method of the terylene FDY oiling agent, which comprises the following steps:
p1, mixing the composite smoothing agent, the bundling agent, the penetrating agent, the antioxidant, the nonionic antistatic agent and the anionic antistatic agent according to the weight ratio, heating to 50-90 ℃, and stirring to fully and uniformly mix the components;
