Definitions
- the present invention is a polyester resin composition having excellent whiteness, spinning stability and melt stability, and in particular, has excellent whiteness itself and is excellent in spinning stability and melt stability.
- the present invention relates to a resin composition comprising a polymethylethylene terephthalate, which does not easily cause a reduction in molecular weight due to coloring and thermal decomposition of a resin composition in a spinning step, and as a result, a high-strength fiber is easily obtained.
- Polymethylene terephthalate fiber has properties similar to nylon fiber such as soft texture derived from low elastic modulus, excellent elastic recovery, and easy dyeing. This is an epoch-making fiber that has properties similar to polyethylene terephthalate fiber, such as wearability, dimensional stability, and yellowing resistance, and is being applied to clothing, carpets, etc. It is being done.
- Polymethylene terephthalate can be polymerized in the same manner as poly (ethylene terephthalate) polybutylene terephthalate, which is chemically similar. That is, terephthalic acid or a lower alcohol diester of terephthalic acid, such as dimethyl terephthalate, and trimethylene glycol (or 1,3-propanediol) are combined with a non-catalytic or metal carboxylic acid in advance.
- the transesterification reaction represented by the formula (1) is carried out in the presence of a catalyst such as a salt, titanium alkoxide, and an organic acid while heating, and then, the titanium alkoxide is treated with titanium alkoxide.
- the polymerization can be carried out by performing a polycondensation reaction represented by the formula (2) under reduced pressure using a catalyst such as a peroxide.
- Polymerization of polymethylene terephthalate is a technology that is different from polyethylene terephthalate and polybutylene terephthalate.
- enumerating these technical issues can be summarized as the following three issues, in particular, whiteness, spinning stability, and melt stability.
- the problem with whiteness is that the polymer is colored yellow during the polymerization stage, so that the resulting fibers and fabrics are also colored, which impairs product performance. Areas that can take advantage of the soft texture, excellent recovery properties and easy-care properties of polyester fibers are particularly useful in innerwear and pantyhose stores. Kings, sportswear, outerwear, etc. are considered promising.
- the whiteness of the fiber is sufficiently high, and therefore, it is necessary for all the dyeings from light to dark to develop vivid colors.
- poly (methylen terephthalate) is liable to be colored during the polymerization stage, and even if fibers or fabrics dyed using such a polymer are produced, the color of the dyed product lacks sharpness.
- the merchantability is significantly impaired.
- the problem with spinning stability is that the polymer contains many impurities, which adversely affect spinning stability. That is, in the polymerization process of polymethylene terephthalate, the cyclic dimer, A large amount of other cyclic and linear oligomers are generated, and they precipitate around the spinning nozzle during spinning, increasing the frequency of yarn breakage and the cleaning of the spinning nozzle (called the wiping cycle). There is. In particular, the amount of the ring dimer is large, which is the main cause of the above problem.
- melt stability of the polymer is poor, the molecular weight of the polymer is reduced by melting, and the polymer is colored.
- the fact that the molecular weight tends to decrease means that the molecular weight decreases at the melt spinning stage even if the molecular weight is increased at the polymer stage.
- Japanese Patent Application Laid-Open No. 5-262628 discloses a technique using a tin catalyst as a polymerization catalyst in order to improve whiteness.
- the polymerization rate is very fast when a tin catalyst is used, but the whiteness is worse than when a titanium alkoxide is used as a catalyst.
- zinc acetate is used as the transesterification catalyst and tin catalyst is used as the polycondensation catalyst, but if only melt polymerization is performed without performing solid-phase polymerization in such a combination, the amount of cyclic dimer will be 3%.
- the spinning stability is not so good because it exceeds 10% by weight.
- Japanese Patent Application Laid-Open No. Hei 8-311177 discloses a spinning process for improving the whiteness of a polymethyl terephthalate and reducing oligomers.
- polymethylene terephthalate obtained by a conventional method is reduced to approximately 190 to 200 ° C under reduced pressure.
- Polymer with intrinsic viscosity of 0.9 or more, b value of 10 or less used as an index for judging chip yellowness, and oligomer content of 1% by weight or less Remethylene terephthalate resin is disclosed.
- terephthalic acid and 1,3-propanediol are transesterified without using a catalyst without using a phosphorus compound or a cobalt compound, and thereafter, tetraethylation is performed.
- butyl titanate titanium butoxide
- solid-phase polymerization is performed to obtain a polymer having an intrinsic viscosity of 1.02.
- a fiber is formed using a polymer having a high degree of polymerization obtained by this known method, a fiber exhibiting sufficient strength cannot be obtained because of a decrease in viscosity at the spinning stage.
- the triunylphosphite-based stabilizer used here has a high sublimation property, and partially sublimates in the polycondensation step performed under a high-temperature vacuum. Deviates from the scope of the present invention. Therefore, the obtained polymer has low melt stability and it is difficult to obtain a fiber having high strength.
- this publication does not even mention the problem of melt stability affecting fiber strength.
- bis (3-hydroxypropyl) ether is described as containing about 4 mol% (more than 2 wt% in weight%) of the polymer. Mer can not be used for clothing as it significantly reduces the melt stability and lightfastness.
- An object of the present invention is to provide a polymethylene terephthalate resin composition which is excellent in whiteness itself and has little coloring even in a spinning stage.
- Another object of the present invention is to provide a polymethylene terephthalate resin composition which, in addition to the above, has excellent spinning stability, is excellent in melt stability, and is not easily reduced in molecular weight by thermal decomposition in the melt spinning process. You can provide things.
- a more specific object of the present invention is to provide a polymethylethylene terephthalate resin composition capable of producing polymethylene terephthalate-based fibers having high whiteness and high strength. It is to provide.
- the present inventors have conducted various studies on a method for producing a polymethylene terephthalate which is excellent in whiteness itself, has little coloring even in the spinning stage, and easily exhibits high strength.
- Lithylene terephthalate has an appropriate viscosity, and the addition of a phosphorus compound and optimization of polymerization conditions have an adverse effect on whiteness and spinning and melt stability.
- the present invention has succeeded in reducing the amount of impurities to be removed, and has reached the present invention. That is, the present invention is a polyester resin composition satisfying the following conditions (1) to (4) and having an intrinsic viscosity of 0.4 to 2.
- the polyester resin composition of the present invention is a polyester resin composition comprising at least 90% by weight of polymethylethylene terephthalate based on the weight of the resin composition. is there.
- polymethylethylene terephthalate refers to terephthalic acid as an acid component and trimethylene glycol (also referred to as 1,3-propanediol) as a diol component. It is a polyester.
- Polymethylene terephthalate which is a component of the composition, may contain another copolymer component in an amount of 10% by weight or less based on the weight of the resin composition.
- copolymerization components include: 5-sodium musulfoysophthalic acid, 5-calimus noreheosophthalic acid, 41 sodium sulpho-2, 6-naphtharene Potassium olevonic acid, 3,5 — benzolenovonic acid benzenesulfonate tetramethylphosphonium salt, 3,5 — dicarboxylic acid benzenesulfonate tetrabutylphosphonium salt, 3,5 — benzenesulfonic acid benzenesulfonate Tributylmethylphosphonium salt, naphthalene 2,6-dicanololevate-14-tetrabutyl phosphonate salt, 2,6-naphthalene 2,6-dicarboxylate tetramethyl phosphonium salt
- the intrinsic viscosity [] (also referred to as intrinsic viscosity) of the polyester resin composition of the present invention needs to be 0.4 to 2.0. If the intrinsic viscosity is less than 0.4, the degree of polymerization of the polymethylethylene phthalate constituting the resin composition is too low, resulting in low fiber strength and spinnability. Becomes unstable. On the other hand, when the intrinsic viscosity exceeds 2.0, the melt viscosity is too high, so that the metering with the gear pump is not performed smoothly, and the spinning property is reduced due to poor discharge.
- a more preferred intrinsic viscosity is 0.6 to 1.5, particularly preferably 0.6 to 1.4, and a polytrimethyl terephthalate having excellent strength and spinnability. Fiber can be obtained.
- the polyester resin composition of the present invention needs to contain a phosphorus compound corresponding to a phosphorus element amount of 10 to 250 ppm. From the polymerization of a monomer to a garment product, it undergoes processes such as melt polymerization, solid state polymerization, chip drying at high temperature, melt spinning, scouring, heat setting, and dyeing. Is very effective in preventing coloration and improving melt stability at each of these stages.
- Polyethylene terephthalate is different from polyethylene terephthalate, which is commonly used for clothing. It is easy to color yellow by melt polymerization, drying and melt spinning, but phosphorus compounds are particularly effective in suppressing these. Polymethylene terephthalate also has a low melt stability, so that the degree of polymerization tends to decrease during spinning. Even when spinning, there is a disadvantage that the strength of the fiber obtained by the reduction in the degree of polymerization does not increase so much. The phosphorus compound has a great effect of suppressing the decrease in viscosity of the polymer.
- an organic phosphorus compound is preferred, and since it is particularly effective in preventing coloration and melting stability and does not adversely affect spinnability,
- R, R 2 , R 3, R 4, R 5, and R 6 are different or homologous, and include a hydrogen atom, an organic group having 1 to 8 carbon atoms, Preferably selected from earth metal.
- one alkoxy group of the phosphorus compound may be a hydrogen atom or an alkyl group having 1 to 8 carbon atoms. I like it. This is because these alkoxy groups are transesterified with trimethylethylene glycol to form a form that is easily dispersed in the polymer. Such a phosphorus compound dispersed in a molecular order is particularly effective in preventing coloring and improving melt stability.
- R, R 2, R 3, R 4, R 5, and R 6 have 9 or more carbon atoms, foaming occurs at the dyeing stage, and it becomes easy to cause staining spots, and strength is increased. It has the disadvantage that it is difficult to increase.
- one alkoxy group of the phosphorus compound may be a hydrogen atom or an alkyl group having 1 to 8 carbon atoms. I like it. This is because these alkoxy groups are transesterified with trimethylethylene glycol to form a form that is easily dispersed in the polymer. Such a phosphorus compound dispersed in a molecular order is particularly
- R,, R 2, R 3, R 4, R 5 and R 6 are all phenoxy groups or
- At least one alkoxy group of the phosphorus compound is a hydrogen atom, or an alkyl group having 1 to 8 carbon atoms, an alkali metal, or an alkaline earth metal.
- Preferred examples of these phosphorus compounds include phosphoric acid, trimethyl phosphate, triethyl phosphate, and triprophosphate.

- the amount of the phosphorus compound contained in the resin composition can be represented by the weight fraction of the phosphorus element contained in the resin composition, and is in the range. Therefore, it is necessary to be 10 to 250 ppm. If it is less than i O ppm, the effects of preventing coloration and suppressing viscosity decrease are not fully exhibited.If it exceeds 250 ppm, these effects are sufficiently obtained, but the polymerization catalyst is partially deactivated. Melt polymerization or solid state polymerization becomes difficult to progress.
- the amount of the phosphorus compound is preferably from 35 to 150 ppm, more preferably from 50 to 120 ppm.
- titan alkoxide such as titan butoxide or titan isopoxide is used as a polycondensation catalyst.
- metal compounds such as antimony.

- the phosphorus compound used in the present invention may react with these polycondensation catalysts to slightly lengthen the polymerization time.
- the amount of the phosphorus element of the phosphorus compound relative to the number of moles of the metal element used as the polycondensation catalyst is required.
- the ratio to the number of moles is preferably set to 0.4 to 3, particularly preferably set to 0.55 to 2.
- Cobalt compounds include cobalt acetate, cobalt formate, cobaltate carbonate, cobaltacetate acetate, cobaltate sulfate, chloride cobaltate, cobaltate bromide, cobaltate hydroxide, nitrate nitrate. Cobalt, carbonated carbonate, etc., may be anhydrous or hydrated.
- cobalt compounds are particularly preferably cobalt acetate, cobalt salt formate, cobalt carbonate, cobalt acetyl acetate, and cobalt sulfate because of their excellent coloring prevention effect.
- the amount of the cobalt compound contained in the polyester resin composition of the present invention can be represented by the weight fraction of the cobalt element contained in the resin composition, and is in the range. Preferably, it is 5 to 20 ppm. If it is less than 5 ppm, the effect of preventing coloration is not sufficiently exhibited, and if it exceeds 200 ppm, the polymer is colored blue or blackish. Preferably, it is 10 to 15 ppm, more preferably 10 to 100 ppm.
- the amount of the cyclic dimer contained in the polyester resin composition of the present invention is not more than 3% by weight based on the weight of the resin composition.
- the cyclic dimer described here is a dimer in which trimethylene terephthalate units are connected in a ring. If this oligomer is contained in the resin composition in an amount of more than 3% by weight, the sublimation property is so high that it precipitates around the spinneret during spinning, on oil nozzles and guides, and the wiping cycle is short. In addition, in severe cases, fluff and thread breakage occur. In order to stably perform long-time spinning for two weeks or more, the content is 2% by weight or less, and more preferably 1% by weight or less.
- the bis (3-hydroxypropyl) ether (HOCH 2 CH 2 CH 20 CH 2 CH 2 CH 2 OH : hereinafter abbreviated as BPE) contained in the polyester resin composition of the present invention is the weight of the resin composition. Should be less than 2% by weight.
- BPE has hydroxyl groups at both ends of the force molecule generated by dimerization of trimethylene glycol as shown in the following formula. It is copolymerized in a batch.
- the amount of BPE produced depends on the polymerization catalyst, additives, polymerization temperature, polymerization time, and the amount of trimethylenglycol.
- the copolymerized BPE has an ether unit with low heat resistance and low light resistance. Therefore, the melt stability and light resistance of the resin composition are reduced.
- BPE did not only adversely affect the resin composition, but that the amount of BPE increased the dyeing properties of the obtained fibers with respect to the disperse dye.
- the amount of BPE is in the range of 0.4 to 1% by weight, normal pressure dyeing is exhibited without significantly reducing heat resistance and light resistance.
- Atmospheric pressure dyeability means, for example, that other fibers that degrade when dyed at a temperature of 100 ° C or higher, such as polyurethane fiber, wool, silk, acetate fiber, etc. It is also possible to dye fabrics that have been composited with natural pressure under normal pressure, greatly expanding the potential of polymethylene terephthalate fibers. This effect is remarkable when the dye concentration is less than about 4% 0 w ⁇ .
- the content of the polyester contained in the polyester resin composition of the present invention is preferably 1% by weight or less, and more preferably 0.4 to 1% by weight.
- the polyester resin composition of the present invention may contain, if necessary, various additives, for example, an anti-glazing agent, a heat stabilizer, a defoaming agent, a coloring agent, a flame retardant, an antioxidant, An ultraviolet absorber, an infrared absorber, a crystal nucleating agent, a whitening agent and the like may be contained in a copolymerized or mixed form.

- the hindered phenol-based oxidation stabilizer may be bound to polymethylethylene terephthalate or may be simply dispersed in the resin composition.
- the amount of the hindered phenol-based oxidation stabilizer in the resin composition is preferably 1% by weight or less based on the weight of the resin composition. This is because if it exceeds 1% by weight, coloring may occur, and even if it is added in an amount of 1% by weight or more, the ability to improve the melt stability is saturated. Preferably it is between 0.02 and 0.5% by weight.
- a whitening agent may be used to improve the whiteness.

- the polycondensation reaction is carried out under a reduced pressure of 1 to 0 rr or less, preferably 0.5 torr or less, at 250 to 290 ° C, preferably 260 to 280 ° C. Is obtained.
- the polycondensation reaction temperature is particularly important, and the higher the temperature, the faster the reaction rate, but the easier it is to color.
- the polymerization is performed at a temperature lower than 260 ° C, the amount of cyclic dimer increases. Therefore, it is preferable to select a reaction temperature by well balancing the reaction rate and the amount of cyclic dimer. Preferred temperatures are 260-280 ° C.
- the molar ratio of the lower alcohol diester of terephthalic acid to the trimethylenglycol transesterification catalyst at the time of charging is 1: 1.3 to 1: 4, preferably 1: 1.5 to 1: 2. It is 5. If the trimethylenglycol is less than 1: 1.3, the reaction time will be significantly longer and the polymer will be colored. Also, when the amount of trimethylenglycol is larger than 1: 4, the amount of BPE generated is larger than 2% by weight. It is necessary to use a transesterification catalyst without fail. Preferred examples include calcium acetate, magnesium acetate, zinc acetate, and titanium acetate. The amount of the transesterification catalyst is preferably from 0.02 to 0.1% by weight based on the terephthalic acid diester used.
- Manganese acetate also acts as a transesterification catalyst. However, since the amount of cyclic dimer exceeds 3% by weight, solid-state polymerization that can reduce the amount of cyclic dimer as described later is used. If not, the use of manganese acetate should be avoided.
- a polycondensation catalyst examples thereof include titanyl alkoxide, typified by titanate tributoxide, titante trisopropoxide, antimony acetate, and antimony trioxide.
- titan trabutoxide is particularly preferred in that the reaction rate is high and the amount of cyclic dimer is small.
- the amount of the polycondensation catalyst is preferably from 0.03 to 0.1% by weight based on the terephthalic acid diester to be used, and the ultimate amount of the resin composition obtained by the first method is preferred.
- the viscosity can reach from about 0.4 to about 0.8.
- the cyclic dimer content is usually 2 to 3% by weight, and the BPE content is 0.2% by weight or less.
- the second method uses terephthalic acid and trimethylene glycol as raw materials.
- terephthalic acid and trimethylene glycol are reacted at a temperature of 200-240 ° C to effect transesterification, and thereafter at least 1 t0 rr or less, preferably 0.5 torr or less.
- the polycondensation reaction is carried out at 250 to 290 ° C under reduced pressure, particularly preferably at 260 to 280 ° C for the same reason as in the first method, to obtain a desired resin composition. .
- the ester exchange reaction product bis (3-hydroxypropyl terephthalate) was obtained at the start of the reaction.
- the molar ratio of terephthalic acid to trimethylene glycol transesterification catalyst at the time of charging is 1: 1.3 to 1: 4, preferably 1: 1.5 to 1: 2.1. 1: If the amount of trimethylenglycol is less than 1.3, the reaction time becomes extremely long and the resin composition is colored. Also, if the amount of trimethylenglycol is greater than 1: 4, the amount of BPE generated will be greater than 2% by weight.
- a transesterification catalyst is not always necessary because the proton released from terephthalic acid acts as a transesterification catalyst, but it is preferable to use it to increase the reaction rate.
- Preferable examples include titanyl alkoxide, which is represented by titanate tributoxide, titante trisopropoxide, and the like.
- the amount of transesterification catalyst is preferably from 0.02 to 0.1% by weight based on the terephthalic acid used.
- titanyl alkoxide typified by titanate lab toxin titanate trisopropoxide, antimony acetate, antimony trioxide, etc.
