Description
Technical Field
The invention belongs to the technical field of spinning oiling agents, and particularly relates to a polyester POY oiling agent and a preparation method thereof.
Background
The trade name of PET polyester (polyethylene terephthalate) silk fabrics is called polyester, and the polyester spinning generally adopts a high-speed spinning-stretching twisting process, namely a Pre-oriented yarn or a partial oriented yarn (POY, pre-Oriented Yarn or Partially Oriented Yarn) and a stretching textured yarn (DTY, draw Texturing Yarn) are combined in two steps, namely a POY-DTY process for short. Currently, the polyester spinning capacity in China is close to 4100 ten thousand tons and accounts for up to 70% of the total world, wherein the annual yield of polyester POY filaments can reach 2500 ten thousand tons. In the chemical fiber spinning and subsequent processing and manufacturing processes, the use of the chemical fiber oiling agent is indispensable, and the chemical fiber oiling agent is required to endow the fiber with good smoothness and cohesion, and greatly reduce static electricity generation or static electricity density so as to ensure that the spinning and subsequent processing are smoothly carried out.
At present, the polyester filament POY oiling agent has serious problems of unstable viscosity temperature and viscosity concentration characteristics when being applied, and is easy to cause phenomena such as broken filaments, broken ends and the like, thereby influencing the production efficiency. The reason is mainly that the oil is generally prepared into emulsion during oiling, spinning is carried out at high temperature, in the spinning process, as the emulsion is heated and water evaporates continuously, the concentration of the oil on the surface layer of the fiber is increased from about 10% to near the anhydrous state, the viscosity of the emulsion is changed accordingly, for example, certain polyether compounds in the oil, particularly monomer components with high content of the random polyether chain segment poly (oxy-isopropyl) are easily separated in a certain concentration and temperature range, a tangential thickening anti-thixotropic fluid type emulsion is formed, the fiber is rubbed with metal or ceramic surface during high-speed operation, the oil attached to the surface of the fiber is subjected to strong shearing action, the polyether components in the emulsion are in a high-viscosity state or viscosity burst at different temperature and concentration ranges, and the phenomenon that the viscosity characteristic of the emulsion is unstable along with the temperature or the concentration of the oil is that the viscosity characteristic of the oil is unstable at the viscosity and temperature. The unstable viscosity-temperature viscosity-concentration characteristic of the oiling agent easily causes obvious tension fluctuation of the fiber in the spinning process, thereby influencing the quality of the fiber. The existing polyester POY high-speed spinning oil has the following common problems: many polyether monomers are not ideal in viscosity-temperature viscosity-concentration characteristics, the molecular weight of the monomers is too large, the viscosity is large at low temperature, uneven oiling is caused, the viscosity is small at high temperature, the oiling agent on the fibers can splash onto a hot roller under the action of centrifugal force, the forming of coke is easily caused by long-time heating, the heat conduction efficiency of a heater is affected slightly, the stretching of tows is uneven, and the number of broken filaments and broken ends is increased, so that the production is affected. The monomer has small molecular weight and generally has a viscosity jump phenomenon, so that the viscosity fluctuation range in the high-speed spinning process is overlarge, uneven oiling can be caused, the coking amount on a hot plate is large, and the quality of the yarn is affected. Therefore, the problem of unstable viscosity-temperature-viscosity-concentration characteristics of the domestic polyester filament POY oiling agent is urgently needed to be overcome, the oiling agent quality is improved, and the market competitiveness is enhanced.
In actual use, because the polyester POY oiling agent needs to play roles in two processes of spinning and texturing, DTY texturing can be completed within one month after the polyester POY filaments are produced, so that the optimal processing performance of the polyester POY filaments can be maintained. And is affected by market fluctuations, a frequent large stock quantity occurs in many factories, or a part of stock is stocked by the sales clients, which results in a storage time of POY filament sometimes up to 3 months or even longer. In the long-term storage process of the POY filaments, the oiling agent attached to the POY filament bundles can permeate into an amorphous area inside the fiber, so that the oiling rate of the surface of the fiber is reduced; and the POY filaments piled for a long time are easy to generate thermal oxidative degradation phenomenon when stored at high temperature in summer, so that the oil content on the surfaces of the POY filaments is reduced. Meanwhile, long-term accumulation of POY filaments can also cause the phenomena of putrefaction, odor and the like of the oiling agent, so that the POY filaments are easy to have low oil content and cannot be subjected to elasticizing production normally, and the quality of the POY filaments is greatly influenced.

Additionally, features described with reference to certain examples may be combined in other examples.
The polyester POY oiling agent comprises the following raw material components in parts by weight:
wherein the polyester POY oiling agent is an oil-in-water emulsion;
the viscosity-temperature viscosity-concentration characteristic regulator comprises: the viscosity regulator, the viscosity regulating auxiliary agent and the water-locking agent are slow release agents, and the viscosity regulator, the viscosity regulating auxiliary agent and the water-locking agent can be gradually released in the use process.
Preferably, the viscosity-temperature-viscosity-concentration characteristic regulator comprises, in parts by weight:
0.3 to 0.5 part by weight of a viscosity modifier;
1-2 parts by weight of viscosity regulating auxiliary agent;
and 4-6 parts by weight of a water locking agent.
As some embodiments of the present invention, the viscosity modifier is selected from one or more of carboxymethyl cellulose, hydroxyethyl cellulose and hydroxypropyl methyl cellulose, polyvinyl alcohol and polyethylene glycol.
Preferably, the polyethylene glycols used in the present invention have a relative molecular weight of between 1000 and 3000.
Preferably, the viscosity modifier comprises:
60-70% of carboxymethyl cellulose and/or hydroxypropyl methyl cellulose and/or polyethylene glycol;
and, 30-40% of hydroxyethyl cellulose, and/or polyvinyl alcohol.
In the viscosity regulator, the selected carboxymethyl cellulose, hydroxyethyl cellulose, hydroxypropyl methyl cellulose, polyvinyl alcohol and polyethylene glycol are all water-soluble polymer tackifiers, when the water-soluble polymer tackifiers are released into the polyester POY oiling agent, the viscosity regulator can be dissolved in a water phase in the polyester POY oiling agent to form a network structure in the water phase, when the temperature of the oiling agent is increased, the viscosity of the water phase can be increased, the fluidity and evaporation rate of the water phase can be reduced, and meanwhile, because the polyester POY oiling agent is an oil-in-water emulsion, the network structure of the water phase can also inhibit long-distance movement of oil phase droplets, further inhibit permeation of the oil phase droplets into polyester fibers, and keep the oil content of the fiber surface at a higher level for a long time.
Further, although the viscosity modifiers are all water-soluble polymer tackifiers, the mechanism of their tackifiers is not exactly the same, wherein the mechanism of thickening hydroxyethyl cellulose mainly involves hydration of molecular chains, so that the molecules swell and form a network structure, thereby increasing the viscosity of the aqueous solution; the polyvinyl alcohol forms a hydration network structure through forming intermolecular hydrogen bonds, so that the viscosity of the aqueous solution is increased, and the aqueous solution is called a net-structure tackifier for a moment; the carboxymethyl cellulose, the hydroxypropyl methylcellulose and the polyethylene glycol form a hydration layer or a hydration shell mainly through molecules thereof in water, and then the intermolecular repulsion and expansion are caused, so that the viscosity of the solution is increased, and the water-soluble macromolecular tackifier is called as a hydration tackifier, for example, the hydroxypropyl methylcellulose is obtained by introducing hydroxypropyl or methyl groups into the cellulose, when the hydroxypropyl methylcellulose molecules are dissolved in the water, the hydroxypropyl and methyl groups interact with water molecules through hydrogen bonds, van der Waals force and the like, so that the water molecules can form a hydration layer around the hydroxypropyl methylcellulose molecules, the hydroxypropyl methylcellulose molecules are wrapped in the shells formed by the water molecules, and the mutual repulsion between the molecules with the hydration layer can prevent the hydroxypropyl methylcellulose molecules from being too close, so that the formation of the hydration shell increases the mutual repulsion between the hydroxypropyl methylcellulose molecules, the increase of the repulsive force between the molecules makes the hydroxypropyl methylcellulose molecules difficult to gather together in the water, and the space between the molecules becomes more viscous solution due to the hydration layer.
According to the invention, through the compounding of the viscosity regulators with the two different tackifying mechanisms, a low-concentration 'net structure tackifier' can be fully utilized to form a weak net structure in a water phase, so that the fluidity and evaporation rate of the water phase are reduced, long-distance movement of oil phase liquid drops is inhibited, the penetration of the oil phase liquid drops into polyester fibers is reduced, and the oil content of the fiber surface is maintained for a long time; meanwhile, the repulsive force among tackifier molecules in the 'hydrated tackifier' can be utilized to ensure that the water phase has better short-distance extension fluidity and lubricating capacity, so that the oil agent is endowed with good adhesion and antifriction performance.
As some embodiments of the present invention, the viscosity adjusting assistant is one or more selected from polyacrylic acid, methacrylic acid, chitosan and sodium alginate.
Preferably, the viscosity regulating auxiliary agent is selected from one or more of polyacrylic acid, methacrylic acid and sodium alginate.
More preferably, the viscosity adjusting aid comprises: 50-70% of polyacrylic acid and 30-50% of sodium alginate.
In the use process of the oil agent, the oil agent is influenced by external environmental factors such as air, light, high temperature and the like, fatty acid and other substances in the oil are easily oxidized, so that the fatty acid is free, the acid value of the oil agent is increased, and the reason why a large amount of antioxidant is usually added in the oil agent is why the viscosity adjusting auxiliary agents such as polyacrylic acid, sodium alginate and the like are selected.
As some embodiments of the present invention, the water-locking agent is one or more selected from hyaluronic acid, sodium alginate, pullulan, algal polysaccharide, and betaine.
Preferably, the water-locking agent is a mixture of hyaluronic acid and pullulan.
More preferably, the water-locking agent is a mixture of 30-40% of small-molecule hyaluronic acid and 60-70% of pullulan.
Preferably, the molecular weight of the small molecule hyaluronic acid is 10-40 ten thousand; the molecular weight of the pullulan is 80-130 ten thousand.
In the water-locking agent, the micromolecular hyaluronic acid has better permeability, can quickly permeate into the oil agent in the use process of the oil agent, and can quickly enhance the lubricity and water-locking capability of the oil agent; the molecular weight of the pullulan is relatively large, so that the water locking capacity of the oil solution can be greatly improved; meanwhile, the pullulan polysaccharide has excellent viscosity and gas barrier capability, when the pullulan polysaccharide is diffused and dissolved into the oiling agent, the water locking capability of the oiling agent can be improved, the evaporation of water is reduced, the viscosity and concentration stability of the oiling agent are kept, the viscosity, temperature and viscosity and concentration characteristics of the oiling agent are improved, the adhesive capability of the oiling agent on polyester fibers at high temperature can be improved, and meanwhile, the anti-splashing capability of the oiling agent can be improved. In addition, in the polyester POY filament production process and in the long-term storage process after the production is finished, the pullulan polysaccharide can also prevent oxygen and the like from entering the oil agent, so that the problems of oxidation and spoilage of the oil agent are solved, and the oxidation resistance of the oil agent is improved.
In addition, the moisture absorption capacity of the hyaluronic acid is particularly strong under low humidity, and the moisture absorption capacity becomes weaker under high humidity, so that the hyaluronic acid does not absorb too much water to reduce the ductility and fluidity of the oil when the water content in the oil is large under low temperature; when the water content in the oil agent is reduced at high temperature, the hyaluronic acid can lock water and improve the stability of the components and viscosity of the oil agent.
Further, the viscosity-temperature-viscosity-concentration characteristic regulator further comprises, in parts by weight:
5-8 parts by weight of nano porous carrier particles;
and 1-2 parts by weight of ethylcellulose.

Adding 50-80 parts by weight of nano porous carrier particles into 90-120 parts by weight of mixed solution of ethanol and water, uniformly stirring, adding 0.1-0.3 part by weight of sodium hydroxide, heating the obtained mixed solution to 45-55 ℃, fully stirring to uniformly mix, slowly dripping 20-30 parts by weight of surface modifier, reacting for 1-2 hours under stirring, adding 10-20 parts by weight of hydroxyl acrylate, reacting for 2-3 hours under stirring at 40-50 ℃, filtering, and drying to obtain the hydrophilic modified porous particles.
Preferably, in the hydrophilic modification treatment, the surface modifier is an amino group-containing siloxane.
Preferably, in the hydrophilic modification treatment process, the volume ratio of the ethanol to the water in the mixed solution of the ethanol and the water is 20-30: 1.
Preferably, in the hydrophilic modification treatment process, the surface modifier is added dropwise within 1-2 hours.
In the hydrophilic modification treatment process, a large number of hydroxyl groups are introduced to the surfaces of porous carrier particles under the catalysis of alkali, so that the porous carrier particles have good hydrophilicity and can be stably dispersed in the water phase in the oil solution.
Further, the preparation process of the viscosity-temperature viscosity-concentration characteristic regulator is as follows:
Firstly, adding the viscosity regulator, the viscosity regulating auxiliary agent and the water locking agent into a proper amount of deionized water, uniformly stirring, adding the nano porous carrier particles, performing ultrasonic dispersion treatment for 20-30 min, filtering, and drying the obtained fixed particles for later use;
Then, adding the ethyl cellulose with the formula amount into a proper amount of organic solvent, and stirring to dissolve; and adding the filtered and dried fixed particles into a solution of the ethyl cellulose, and granulating by atomization drying to obtain the nano-porous carrier particles with the surfaces coated with the ethyl cellulose.
Preferably, the content of the ethyl cellulose in the solution of the ethyl cellulose is 3-6%.
As some embodiments of the present invention, ethyl cellulose may be dissolved using an organic solvent such as acetone, ethanol, xylene, and the like.
Further, the polyester POY oiling agent also comprises 0.01 to 0.1 weight part of cross-linking agent according to weight parts.
Preferably, the cross-linking agent is 1, 4-butanediol diglycidyl ether, the hyaluronic acid is a linear polymer, and by adding a trace amount of cross-linking agent into the polyester POY oiling agent, after the hyaluronic acid is released, the cross-linking agent can promote the linear polymer of the hyaluronic acid to crosslink, so that a network structure is formed, and the moisturizing and water locking capacities and effects of the polyester POY oiling agent are optimized.
It should be noted that the purpose of adding the crosslinking agent to the oil is to prevent crosslinking of the hyaluronic acid before the hyaluronic acid is released from the viscosity-temperature viscosity-concentration property regulator, so that the release speed of the hyaluronic acid and the degree of crosslinking and interpenetrating with other network structures can be greatly slowed down, and meanwhile, the dispersion uniformity of the hyaluronic acid can be affected, so that the effect of the viscosity-temperature viscosity-concentration property regulator is obviously reduced.
Furthermore, the polyester POY oil solution also comprises 2-5 parts by weight of hyaluronic acid glyceryl monostearate derivatives, wherein the hyaluronic acid glyceryl monostearate derivatives can form a net structure in an oil phase in the oil solution on the one hand, so that the strength of an oil film is enhanced, more importantly, the hyaluronic acid glyceryl monostearate derivatives are amphiphilic substances, the dissolving and stable dispersing capabilities of the oil phase in an aqueous phase can be promoted, the stability of the polyester POY oil solution emulsion is improved, the phase separation of the polyester POY oil solution emulsion is inhibited, and the thixotropic fluid type emulsion thickened by shear force is resisted.
Further, the smoothing agent is a mixture of polyether and mineral oil.
