Description
Technical Field
The invention relates to the field of polyester spinning oil, in particular to a polyester FDY oil and a preparation method thereof.

However, most domestic terylene FDY oil agents still depend on import at present, although the domestic oil agents have certain progress, the quality of the FDY oil agents still has certain difference compared with the imported oil agents, the FDY oil agents generally easily cause abnormal spinning phenomena such as broken filaments, broken ends, white powder, tension fluctuation, winding and the like in spinning application, and the FDY oil agents are easily difficult to dye, uneven in dyeing and the like in later dyeing, so that the quality of fibers is seriously reduced.
For example, a chinese patent publication discloses "a middle strength heavy denier polyester FDY yarn and a method for producing the same", publication No. CN102443861A, which discloses a middle strength heavy denier polyester FDY yarn and a method for producing the same, the polyester FDY yarn being prepared by the following method: according to the direct spinning FDY process route, PET melt is extruded from a spinneret orifice of an oval spinneret plate for spinning, then is cooled and solidified into filaments through side air blowing in sequence, and then is oiled by an oil tanker, heated and drawn by two pairs of hot rollers for shaping, and is added with a main network to be wound into an FDY spinning cake.

In order to solve various problems of FDY oil in spinning application, the invention also specifically selects various components and additives in oil preparation.
The problems of yarn breakage and yarn breakage during spinning are often caused by insufficient smoothness or permeability of the finish. In terms of smoothness, the selected monomers mainly comprise three categories of synthetic fatty acid ester, industrial white oil and polyether substances (the synthetic fatty acid ester and the industrial white oil are classified as base oil and the polyether substances are classified as smoothing agents), the smoothness performance of the monomers is comprehensively evaluated through measuring the viscosity and the fluidity of the monomers and the dynamic and static friction coefficients after fibers are oiled, and the smoothing agent monomers are screened or adjusted to solve the problem of insufficient smoothness of the existing oil agent. In terms of permeability, a monomer with lower surface tension is selected as a penetrant, such as C12-C14 fatty alcohol block polyoxyethylene polyoxypropylene ether (EO/PO is 1-1.4, molecular weight is 950-1500) which is a special polyether, and polyether modified silicone oil is added in the additive to be used as a surface tension reducer to reduce the surface tension of the oil agent.
The white powder problem in spinning is often caused by insufficient smoothness and permeability of the finish and insufficient oil film strength of the finish to the fiber, and insufficient finish bundling property affects the white powder, and among these, the white powder problem is often caused by insufficient oil film strength. For the problem of insufficient oil film strength, the invention selects monomers with high oil film strength during formulation design, for example, synthetic fatty acid ester with high oil film strength is preferred for base oil, fatty acid polyoxyethylene ester with high oil film strength is preferred for other components (smoothing agent, bundling agent and emulsifier), and oil film enhancer polyoxypropylene stearate is added into the additive to enhance the oil film strength. For the oil agent bundling property, which is an index for evaluating the cohesion capability during fiber tow processing, the general oil agent has good smoothness, poor bundling property, good oil agent bundling property and poor smoothness, in order to give consideration to both good smoothness and bundling property of the oil agent, the invention measures the monomer viscosity, the fluidity and the dynamic and static friction coefficients after the fiber is oiled, and when designing the oil agent formula, oleic acid polyethylene glycol 400 diester, ricinoleic acid polyoxyethylene ester, isotridecanol polyoxyethylene ether and C4-C12 fatty alcohol random polyoxyethylene polyoxypropylene ether are selected as the bundling agent.
For the problem of tension fluctuation of the filaments during spinning, the coking phenomenon of an oiling roller is serious due to poor heat resistance of an oiling agent, so that the tension fluctuation of the fibers is obvious in the spinning process. In addition, when oiling, the oil agent is prepared into emulsion for use, and because spinning is carried out at high temperature, the concentration of the oil agent in the emulsion is continuously increased along with continuous heating and water evaporation of the emulsion, and the viscosity of the emulsion is changed therewith. When the viscosity-temperature viscosity-concentration characteristic of the oil is not ideal, namely, the problem of tension fluctuation can be caused when the viscosity of the emulsion fluctuates greatly along with the temperature or the concentration of the oil during spinning. In the invention, the oil agent monomer with better heat resistance is preferably selected in the design of the oil agent formula, wherein the base oil is selected from synthetic fatty acid ester with high boiling point and large latent heat of vaporization and industrial white oil with high flash point. For the problem that the viscosity-temperature viscosity-concentration characteristic of the oil agent is not ideal, the viscosity mutation phenomenon of the oil agent is avoided, monomers with high thermal decomposition temperature, such as a smoothing agent, a bundling agent and an emulsifier, are selected, and more polyether substances (fatty acid polyoxyethylene ester) or polyether substances containing ester bonds are selected, so that the molecular weight distribution of the polyether substances is widened, and the compatibility among the components of the oil agent and the overall stability of the oil agent are improved.
The winding problem of the yarn during spinning is often due to insufficient bundling property and antistatic property of the finish. For antistatic property, the anionic surfactant with polyether structure is adopted, and the invention selects polyether phosphate ester salt and polyether sulfate ester salt, which not only have oleophylic hydrocarbon group, but also have hydrophilic strong polar group, and have strong moisture absorption and conductivity, and simultaneously can keep better antistatic property under various humidity conditions.
The problem of difficult dyeing during dyeing is often solved by the whiting problem during spinning because the spun silk is much whiting. In addition, the dyeing difficulty can be caused due to insufficient sizing property of the oil agent, and the weight percentage of the industrial white oil added into the base oil is 8-17%, so that the sizing property of the oil agent is ensured.
The problem of uneven dyeing during dyeing is often caused by severe foaming or insufficient uniformity of finish during use. For the severe foaming of the oil agent in use, the invention adds the defoaming agent into the additive. The invention adds penetrant and polyoxyethylene laurate for the lack of oil agent uniformity, wherein the polyoxyethylene laurate has good smoothness and bundling property and excellent level dyeing property.
In the oil agent, the base oil, the smoothing agent, the bundling agent, the antistatic agent and the penetrating agent are difficult to form uniform and stable oil agent or emulsion due to obvious difference of hydrophilic-lipophilic balance value (HLB value). Therefore, after the monomer types and contents of the components are determined, the components and contents of the emulsifier need to be reasonably designed, so that the prepared oil agent and oil agent emulsion are uniform and stable, and the particle size of the emulsion is small. The oil agent is used by being prepared into emulsion, so the final oil agent needs to be prepared into partial hydrophily, and the HLB value of the oil agent is 12-18. In addition, stabilizing agents of oleic acid and hexadecanol are added into the additive, so that the oil agent is uniformly dispersed for a long time and is not layered. Meanwhile, the surface tension value of the oil emulsion which is prepared into a certain concentration (generally 15-18%) is also reasonable, and the surface tension value of the oil emulsion after the formula design is 20-40dyn/cm (a test value at room temperature and under standard atmospheric pressure), and the oil emulsion has better performance in various aspects during application.
Preferably, the additive of the oil agent further comprises an anti-yellowing agent, the amount of the anti-yellowing agent is 0.1-2 wt% of the total amount of the oil agent, the molecular weight of the anti-yellowing agent is 1000-1500, and the anti-yellowing agent has the following general molecular structure:
wherein x is the mole number of the oxyethylene group, and R is acyl.
The spun polyester filament yarns are processed into cloth in a textile mill, and then dyed in a printing and dyeing mill, so that a certain circulation period exists, and if the circulation period is too long, the spun polyester filament yarns are easy to turn yellow and affect subsequent processing. After the fabric is yellowed, the fabric needs to be whitened again through certain process treatment before dyeing, and after the fabric is bleached by a substance with strong oxidizing property, the fiber material is oxidized, so that the strength of the fiber is reduced, and the total light reflectivity of the fabric is reduced and the brightness of the fiber is reduced due to the fact that the whiteness is improved through a bluing process. In order to further solve the yellowing problem before processing of the polyester filament yarn and save the bleaching process, so that the fiber has better strength and performance, 0.1-2 wt% of an anti-yellowing agent is added in the preparation of the polyester FDY oiling agent, the general formula of the molecular structure of the anti-yellowing agent is shown as the above formula, the main body of the anti-yellowing agent is thioester, and when the anti-yellowing agent is used, the anti-yellowing agent can effectively decompose hydroperoxide in a system and convert the hydroperoxide into a stable product, so that the system is free of color change, non-toxic and non-colored, and is suitable for the fiber; because the terylene FDY oil agent is prepared into emulsion for use, the anti-yellowing agent in the prior art is usually insoluble in water, and the use of the non-soluble anti-yellowing agent can cause the particle size of the oil agent emulsion to be increased, the emulsion to be dispersed unevenly and even the phenomena of layering and turbidity, therefore, when the anti-yellowing agent is synthesized, a polyoxyethylene chain segment is introduced, and the introduction of the hydrophilic polyoxyethylene chain segment improves the compatibility of the anti-yellowing agent and a water phase and the overall stability of the oil agent emulsion, and on the basis, the anti-yellowing agent can better exert the anti-yellowing performance in the oil agent; in addition, the anti-yellowing agent also has excellent thermal stability and smoothness of polyether substances containing ester bonds, and has the advantages of high oil film strength, low surface tension, high wetting speed, low foaming capacity and high defoaming speed, wherein, the thermal stability endowed by the polyether structure containing ester bonds can meet the requirement of anti-yellowing of oil solution and fiber at a high temperature for a long time, meanwhile, the diester-terminated polyether structure endows excellent smoothness and high oil film strength, the ester bond-containing polyether structure endows low surface tension and high wetting speed, which are beneficial to rapid and uniform oiling, the ester bond-containing polyether structure endows low foaming capacity and high defoaming speed which are consistent with the performance requirements of the oil agent, meanwhile, due to the ester bond, the oiling agent is easier to combine with the polyester fiber containing a large amount of ester bonds, and the anti-yellowing agent is stably attached to the surface of the fiber for a long time after oiling.
Preferably, the preparation method of the anti-yellowing agent comprises the following steps: carrying out condensation reaction on methyl acrylate and hydrogen sulfide at 65-70 ℃ under the catalysis of sodium acetate at 1-3bar to prepare an intermediate product dimethyl thiodipropionate; then, carrying out ester exchange reaction on the intermediate product dimethyl thiodipropionate and polyethylene glycol monolaurate at the temperature of 120 ℃ and 135 ℃ under normal pressure and under the catalysis of sulfuric acid to prepare the anti-yellowing agent; wherein, the mol ratio of the methyl acrylate to the hydrogen sulfide is 2-2.1:1, and the dosage of the sodium acetate is 10-20mol percent of the methyl acrylate; the molar ratio of dimethyl thiodipropionate to polyethylene glycol monolaurate is 1: 2-2.1; the dosage of the sulfuric acid is 5-10 mol% of dimethyl thiodipropionate.
When the anti-yellowing agent is prepared, firstly, methyl acrylate and vulcanization can be subjected to condensation reaction under the catalysis of sodium acetate to prepare a dimethyl thiodipropionate intermediate, then the dimethyl thiodipropionate intermediate is subjected to ester exchange reaction with polyethylene glycol monolaurate under the catalysis of acid, and during the reaction, methanol molecules are continuously removed to prepare the anti-yellowing agent.
A preparation method of a terylene FDY oil agent comprises the following preparation steps:
(1) proportionally adding the emulsifier, the bundling agent, the antistatic agent and the penetrant into a reaction kettle, and stirring at the stirring speed of 500-600r/min at the temperature of 40-70 ℃ for 0.5-1 h;
(2) and (3) putting the base oil and the smoothing agent into the reaction kettle, continuously stirring for 45-60min, then putting the additive, stirring uniformly, naturally cooling and filtering to obtain the terylene FDY oiling agent.
Therefore, the invention has the following beneficial effects:
(1) according to the invention, through selection and proportioning of monomers, the prepared FDY oiling agent has good comprehensive performances of smoothness, bundling, static resistance, permeability, heat resistance, sizing and uniform coating, has good spinnability, greatly reduces abnormal broken filaments, broken ends, white powder, tension fluctuation and winding phenomena, and can obviously improve the high-quality product rate under the same spinning process conditions. In the subsequent printing and dyeing, the phenomena of difficult dyeing and uneven dyeing are reduced, and the M rate of fiber dyeing is improved;
(2) the anti-yellowing agent suitable for being used in the oil agent is prepared, so that the FDY oil agent has excellent anti-yellowing capability, the yellowing phenomenon of fiber products in long-term circulation is reduced, and the investment on a whitening process before dyeing is reduced or even the whitening process before dyeing is omitted.
