Description

[Detailed description of the invention]

The present invention relates to a composition for treating polyamide fibers or polyester fiber yarns, which is useful for drawing and frictionally false twisting polyamide fibers or polyester fiber yarns at high speeds. More specifically, the present invention relates to a raw yarn treatment composition in which almost no scum accumulation is observed on a high-temperature heater during high-speed drawing friction false twisting. The purpose of the present invention is to reduce the frictional fluctuation with the contact body and reduce the frictional resistance when spinning raw yarn for friction false twisting at high speed, and to improve the initial yarn winding property during high-speed false twisting processing. In addition, the friction false twisting device significantly reduces the white powder that tends to be generated around the machine during high-speed processing, improving workability, and improving the strength, elongation, crimpability, and level dyeing of crimped yarn. An object of the present invention is to provide a processing composition for yarn that can provide stable processability such as properties. Recently, a method of drawing and simultaneously false-twisting polyamide fibers and polyester fiber yarns has been implemented, but the speed of this drawing false-twisting process has changed from the conventional spindle method to the friction false-twisting method (hereinafter referred to as Frixion). Since then, the speed has been dramatically increased. Even the friction method has been further speeded up due to advances in various mechanical equipment, and recently it is rapidly progressing from 400m/mim to 1000m/mim. However, as the processing speed increases, the contact pressure between the yarn and various contact bodies (e.g. guides, rollers, heaters, etc.) increases.
As processing speed increases, the heat treatment temperature increases, and yarns are often subject to increasingly harsh conditions. For example, as processing speed increases, the friction between various contact bodies increases significantly, resulting in increased occurrence of white powder, fluff, and yarn breakage due to fiber damage, resulting in decreased processability. Furthermore, as the yarn speed increases, the speed of the rotating section naturally increases, which greatly reduces thread threading performance and other operations. In addition, a phenomenon that becomes more noticeable with high-speed processing is that the false-twisting speed naturally increases correspondingly, so a very large centrifugal force is exerted on the yarn, and conventionally well-known processing agents do not apply processing agents to the fibers. It is squeezed out from the surface and shaken off, resulting in an increase in the amount scattered onto the heater. As a result, the heater becomes seriously contaminated, and in extreme cases, the problem arises that so-called tar flows down the grooves of the heater. Additionally, if the treatment agent contains components that are easily decomposed by heat, it will gel on the heater and leave a non-volatile sludge-like substance, which will drastically reduce the passage of yarn.
This causes fluff to occur in the processed yarn, abnormal crimping, and finally yarn breakage. Therefore, in order to increase productivity, the heater must be cleaned frequently. However, frequent cleaning of the heater will conversely reduce productivity, resulting in an increase in costs. In order to solve these problems, heat-resistant oils have recently been studied, and oils containing various polyether compounds as main components have been frequently proposed. That is, lubricants made of copolymers of propylene oxide and ethylene oxide have been well known for a long time, and their general characteristics are clear. However, a more detailed study reveals that, in general, when the copolymerization ratio changes, the properties of a copolymer of propylene oxide and ethylene oxide also change significantly. For example, they exhibit considerably different behavior depending on the number of terminal groups, the copolymerization ratio of propylene oxide and ethylene oxide, the molecular weight, and even the substances blended. Additionally, copolymers of propylene oxide and ethylene oxide are generally water-soluble, and it has been experimentally confirmed that as the copolymerization ratio of ethylene oxide increases, the water solubility increases, but on the other hand, the amount of residue after heating increases. . Conversely, when the copolymerization ratio of propylene oxide increases, the cloud point becomes extremely low at a certain ratio, making the aqueous solution extremely unstable, and eventually a stable aqueous solution cannot be obtained unless an emulsifier is mixed in. shows. Therefore, copolymers of propylene oxide and ethylene oxide inherently include a wide range of contents that should be limited in accordance with the individual technical problems to be solved. To explain this point more specifically, copolymers of ethylene oxide and propylene oxide are generally stable against oxidation and thermal decomposition at temperatures below 200°C, but decompose when exposed to high temperatures over 200°C for long periods of time. After decomposition, it forms sludge and varnish-like residues as well as deposits. However, it is well known that it produces less sludge than mineral oil or synthetic ester compounds. However, among polyether-based lubricants, polyethylene glycol, which is made only of ethylene oxide, has a higher amount of sludge remaining after heating than a copolymer of propylene oxide and ethylene oxide, so it cannot be used as a processing agent pace for high-speed processing. However, in order to reduce the amount of sludge remaining, the copolymerization ratio of propylene oxide is high, that is, the copolymerization ratio of propylene oxide and ethylene oxide (hereinafter
It has been found that it is sufficient to use a material in which the ratio (referred to as PO/EO) is 35/65 (mol %) or more, that is, the copolymerization ratio of propylene oxide is 35 mol % or more. However, this property does not directly apply to the treated raw yarn for high-speed false twisting, and even if such a polyether lubricant is used alone, workability and processability are still unstable. be. Therefore, an antistatic agent is usually used in combination. However, in general, anionic activators, nonionic activators, and other cationic and amphoteric activators, which are well known as antistatic agents, are used in conventional oil agents, such as those disclosed in Japanese Patent Publication No. 52-47079 and Japanese Patent Application Laid-open No. 155796/1983. If the amount used in the example is used as is, scum will accumulate on the heater in several hours to several days during high-speed processing, which is the phenomenon of the present invention, but a tar phenomenon will occur and the thread passability will be reduced. It becomes extremely bad. Therefore, simply reducing the amount of antistatic agent in order to reduce the scum that accumulates on the heater will reduce heater scum. However, if it is less than 4.0%, the heater scum will be reduced compared to the one using about 10 to 15%, but the initial yarn machinability and processability will become unstable. For example, the anionic activator proposed in Japanese Patent Publication No. 52-47079 includes a general formula represented by Na and K salts of uraric acid, palmitylic acid, oleic acid, etc.

% (by weight) or more of anionic antistatic agents are commonly used. In addition, JP-A-50-155796 discloses that polyether-based lubricants contain 35-95% (by weight) of polyoxyethylene ethers or esters containing long-chain alkyl, and 4-50% of ordinary nonionic activators. (by weight), 1 to 30% (by weight) of a phosphate metal salt of a higher alcohol to which ethylene oxide and propylene oxide are added, and further 1 to 30% (by weight) of a metal salt of an alkyl sulfonate. However, in this invention, the anionic activator and the nonionic activator always coexist, and even if 1 to 4% (by weight) of the anionic salt is used, it is difficult to reduce heater scum during high-speed processing. Therefore, the present inventors used as little antistatic agent as possible and even during high-speed machining, there was almost no accumulation of scum on the heater, and the processability and workability were excellent, and problems such as antistatic properties were solved. As a result of conducting studies to overcome this problem, we found that factors such as the electrostatic stability of the oil as a whole and the solubility and dispersibility of the antistatic agent used in polyether play an extremely critical role. From this point of view, we further pursued an antistatic agent that could ideally be used in combination with polyether, and surprisingly found that a metal salt of a long-chain monoolefin dicarboxylic acid was used in combination with a phosphate-based or sulfonate-based anionic activator. When doing so, they discovered that the oil agent as a whole exerts the desired effect and arrived at the present invention. Thus, according to the present invention, the polyether lubricant is substantially composed of a polyether lubricant and an anionic component, in which case [A] the polyether lubricant has a copolymerization ratio of propylene oxide and ethylene oxide of 35/6.

It is composed of at least one of amine salts, organic amine salts, and alkali metal salts of sulfonate compounds, and [] and [] and/or [] are present in the treatment composition in an amount of 0.5% (by weight) or more and 4.0% or less Provided is a processing composition for raw yarn for high-speed drawing and friction false twisting, characterized in that the composition is blended in a range of (weight). The lubricant in the oil used in the present invention includes:
As already mentioned, the well-known polyether compound consisting of a copolymer of propylene oxide and ethylene oxide does not necessarily mean that any polyether can be used, but the copolymerization ratio of propylene oxide and ethylene oxide can be blended. In relation to other compounds blended into polyethers, especially anionic compounds that are used in combination with salts or ester salts of the compound represented by formula (1),
It is made of one or more random or block copolymers with a PO/EO ratio of 35/65 to 90/10 (mol %) and an average molecular weight of 1000 to 15000. In particular, in the present invention, it is suitable for high-speed processing. A special feature of this product is that it does not use emulsifiers, which are commonly used in oil formulations, in order to extremely reduce scum accumulation on the heater. That is, a material having a self-emulsifying property or a material close to self-emulsifying and capable of dispersing in an anion content of [B] of 0.5 to 4.0% (by weight) is used. However, there is no problem in adding a small amount of a volatile emulsifier for a completely different purpose than for emulsification. On the other hand, if the copolymerization ratio of EO in the PO/EO ratio becomes extremely high, water solubility is basically obtained without the need to add any emulsifier. However, polyethylene glycol and polyether compounds with a low PO ratio are difficult to use because they substantially accumulate heater scum during false twisting.
It is not desirable to increase the EO ratio. Therefore, the polyether lubricant [A] used in the present invention is limited to polyethers having a PO/EO ratio of 90/10 to 35/65 (mol %). More specifically, in a preferred embodiment of the present invention, the polyether is a random copolymer with an average molecular weight in the range of about 1000 to 15000, preferably 2000 to 10000, and/or
Alternatively, one type or a mixture of two or more block copolymers are used, but those with a relatively low molecular weight of about 1000 to 4000 are used to smoothen the frictional behavior of the fiber surface in the range from room temperature to high temperature. and 5000～
Approximately 15,000 items, each with at least one type of 10
They are used in a ratio of ~90:90 to 10. If the average molecular weight is less than 1,000, smoke generation will increase, and if the average molecular weight exceeds 15,000, it will be difficult to significantly reduce the scum on the heater, and furthermore, the viscosity will increase, resulting in significantly poor workability. This is undesirable. Further, regarding random copolymers and block copolymers, random copolymers having a lower phase inversion viscosity are more advantageous, but there is no particular limitation. The polyethers used in the present invention can be prepared by conventionally known methods such as monohydric to polyhydric alcohols, monocarboxylic acids to polycarboxylic acids, monoamines to polyhydric amines, mercaptans, and ethylene oxide or propylene oxide. A terminal group having a reactive active group can be used. The type and number of terminal groups of these polyethers are not particularly limited, but particularly preferable terminal groups are those having a boiling point of 200°C or less, such as those of monohydric alcohols or polyhydric alcohols. If we compare, for example, butanol, a lower monohydric alcohol, and sorbitol, a hexahydric alcohol, the former is superior. Regarding the number of terminal groups, the smaller the number, the more preferable n>...6>5>4>
3...>1 is preferable. The essential component [B] to be used in combination with the polyether lubricant [A] is the following general (1) obtained by reacting an aminodicarboxylic acid or its derivative with an aliphatic acyl halide or a sulfochloride.

However, [n represents a positive integer of 1 or 2] General formula (3) and R-COCl or R-SO ₂ Cl (3) [R is an alkyl group, alkenyl group, or fluoroalkyl group having 8 to 22 carbon atoms] ] It can be obtained by reacting a fatty acid halogen compound or an aliphatic sulfochloride compound consisting of the following by a known method. For example, specific examples of aminodicarboxylic acids include aspartic acid and glutamic acid. On the other hand, as the fatty acid chloride, an ordinary acid chloride compound of a higher fatty acid having 8 or more carbon atoms is used, and similarly, a fluorofatty acid derivative in which hydrogen atoms are substituted with fluorine is also used. In the case of sulfochloride, a sulfochloride compound obtained by halogenating the corresponding sulfonic acid by a commonly known method is used. Compounds represented by general formula (1) are represented by general formulas (2) and (3).
A terminally neutralized compound of general formula (1) is synthesized by reacting in the presence of a dehydrochlorination agent, and further alkali hydroxide such as lithium hydroxide, caustic soda, caustic potash, or ammonia or monoethanolamine, diethanolamine, It can be produced by neutralization using alkanolamines such as triethanolamine, and further alkylamines such as trimethylamine, triethylamine, tributylamine, and laurylamine. Of course, it can also be obtained by other methods, such as by subsequent hydrolysis using aminodicarboxylic acid esters, and the production method itself is not limited in any way by the present invention. Furthermore, the compound of the above general formula (1) can also be used in the form of an ester with a compound having a hydroxyl group. In this case, the compound having a hydroxy group for obtaining the ester derived from the compound (1) above is a compound having at least one hydroxy group in the molecule, and is a single compound or a mixture thereof. That is, various alcohols such as butanol, octanol, 2-ethylhexanol, decyl alcohol, tridecyl alcohol,
Tetradecyl alcohol, octadecyl alcohol, etc., such as natural alcohols made from coconut oil or beef tallow, or synthetic alcohols made by Ziegler method, oxo method, etc., can be used. Also, various polyhydroxy compounds having two or more hydroxyl groups, such as 1.6-hexanediol, neopentyl glycol, 9.10-dihydroxystearyl alcohol, trimethylpropane, pentaerythritol, and ricinoleyl alcohol having an unsaturated bond in the molecule. , acetylene diols, etc. can also be used. Most preferably, this is achieved by using an ester of an oxyacid or its alcohol having a hydroxyl group and a carboxyl group in one molecule, such as monooxycarboxylic acid glycolic acid, lactic acid, and other monooxypolycarboxylic acids such as apple. Other dioxycarboxylic acids such as acids and citric acid include glyceric acid and tartaric acid. Furthermore, esters of oxyacids with alcohols, such as methyl ricinoleate, can also be used. In order to obtain the desired effect, the ester compound must have at least one carboxyl group and must be a salt obtained by neutralizing the carboxyl group or saponifying the ester moiety. . Further, the degree of neutralization or saponification may be either complete or partial. Here, examples of the salt include alkali metal salts, ammonium salts, organic amine salts, etc., or a mixed salt having two or more of these salts in the same molecule may be used. Examples of alkali metal salts include Na, K, and Li, with Na and K being particularly good. Examples of organic amine salts include monoethanolamine, which is an alkanolamine;
Examples include diethanolamine, dibutylethanolamine, triethanolamine, and alkylamines such as triethylamine, tributylamine, oleylamine, and octylamine. Next, the aforementioned compounds suitable for the present invention will be listed.

At least one or more of amine salts, organic amine salts, and alkali metal salts of sulfonate compounds having at least one alkyl group and sulfonic acid group are blended so that the total anion component is 0.5 to 4.0%. do. Among the anionic compounds used in combination with the salt or ester salt of the compound represented by formula (1), examples of phosphorus-containing compounds consisting of phosphate compounds include higher alcohols, higher alkyls, and polyoxyalkylenes of alkyl-substituted aromatic compounds. It consists of an ammonium salt, an organic amine salt, and an alkali metal salt of a phosphoric acid ester of a compound whose terminal hydroxyl group is an ether, and is represented by the following general formula. [However, R represents a saturated or unsaturated aliphatic group having 8 to 18 carbon atoms or an alkyl-substituted aromatic group having 1 to 9 carbon atoms, and R' represents a hydrogen atom or a methyl group, but hydrogen atom and methyl In other words, it may be a copolymer of propylene oxide and ethylene oxide. n is a positive integer of 0 to 15, m is 1 or 2, X is ammonium salt, organic amine salt, Na,

Representative examples include ammonium salts, triethanolamine salts, sodium salts, potassium salts, and even lithium salts of phosphate esters such as octyl, lauryl, and oleyl. Also used are phosphoric acid ester salts made of polyoxyalkylene ethers obtained by adding ethylene oxide or propylene oxide to higher alcohols or alkylphenols, or even ethylene oxide and propylene oxide. Among these phosphoric acid ester salts, the most effective in the present invention are those added to ethylene oxide and propylene oxide to higher alcohols or aromatic compounds substituted with alkyl groups. Alkali metal salts such as sodium and potassium of phosphate esters obtained from polyoxyl alkylene ethers are most preferred, followed by organic amine salts and ammonium salts. In addition, as for the sulfonate compound [] as another component used in combination, at least 1 sulfonate compound in 1 molecule
Ammonium salts and organic amine salts of sulfonate compounds having more than one alkyl group and sulfonic acid;
Consisting of alkali metal salts, specifically, the simplest sulfonate compounds include alkyl sulfonates containing an alkyl group having 8 to 18 carbon atoms, sulfonates such as alkanesulfonates, dodecylbenzene, and laurylbenzene, nonylphenol sulfonates, and dialkylnaphthalenes. , sulfonates such as monoalkylnaphthalene, sulfonates of alkyl diphenyl ethers, ammonium salts such as alkylhydroxyphenyl ether sulfonates, organic amine salts, and alkali metal salts.

Examples include amine salts, organic amine salts, and alkyl metal salts such as 2-hydroxypropylsulfonate, alkyl or alkenylcarboxy-2-hydroxypropylsulfonate, sulfoalkyl ester, and sulfoacetate. However, the invention is not limited to these in any way; amine salts, organic amine salts, and alkali metal salts of sulfonate compounds having surface-active properties and having at least one higher alkyl group and sulfonic acid group in one molecule may be used. . Among these sulfonate salts, alkali metal salts are most preferred, followed by organic amine salts and ammonium salts. A mixture of [A] component and [] component [] component and/or at least one component []
species or more, and the total amount of the anionic compound is 0.5
It is blended at ~4.0% (by weight), preferably from 1.0 to 3.0% (by weight). Therefore, considering only the anion components, two or more types will be blended.
In particular, the present invention aims to solve two mutually contradictory problems, such as antistatic properties to enable high-speed drawing and false twisting with a minimum amount of anionic components added, and minimizing heater scum. The above anions were blended and their synergistic effects were ascertained.
Although the details of why the synergistic effect is exerted are unknown, when a polyether lubricant is attached to a yarn and rubbed, it has a large negative electrostatic charge. On the other hand, by adding the component [ ], the frictional static electricity of the yarn can be neutralized, that is, it can be electrically stabilized, thus improving workability. I think so. However, when [] ingredients are used alone, it is 4.0
% or less, the processability is still unstable. Therefore, simply increasing the amount will increase heater scum, which is not preferable. Therefore, by further adding at least one or more of the components [] and/or the components [] to the mixture of components [A] and [], the total amount of anions is 4.0% or less and stable as in the present invention. It was found that this effect can be obtained. In other words, as an anion, the component [] is used as a base, and either the component [] or the component [] is added to it, but it is more preferable to use both in combination to achieve control during high-speed machining with the minimum amount of anion component. Electricity, heat resistance, etc. are improved. Regarding the amount added, the total amount as anionic components is 0.5 to 4.0% (by weight), preferably 1.0 to 3.0% (by weight), but if there are two anionic components, among them []
The component is always used in an amount of 50% or less (by weight) based on the total amount of anionic components. Moreover, in the case of three or more components, 30% (weight) or more is used. Also〔〕
The ratio of the component and the component [] may be about 1:1. However, it is not limited in any way. Although the principle by which a stable effect can be exerted by using the component [ ] and/or the component [ ] in combination is not clear, it is presumed that the dissolution and dispersibility of the anionic component in polyether is improved. Ru. In the present invention, a commonly used known nonionic activator (ester or ether activator with an amount of 15 moles or less as polyoxyethylene) can be used in combination to the extent that the accumulation of heater scum does not increase. . What is high-speed stretching friction false twisting in the present invention?
Refers to processing at a yarn speed of 400m/mim or more, preferably 600m/mim or more, and the effect of the present invention is
Even in frictional false-twisting processing of 600m/mim or more and about 1000m/mim, it is found to be more effective than conventionally known oil agents. The method of applying the composition of the present invention to threads is normally carried out using a 5.0 to 15.0% (by weight) aqueous emulsion, and the amount of the treated product applied varies depending on the type of fiber, but for example, when using polyester fiber threads, 0.1~0.5
% (weight) preferably within the range of 0.2 to 0.35% (weight) (based on the weight of the fiber). If it is less than 0.1%, the composition of the present invention will adhere unevenly, resulting in uneven crimping. If it exceeds 0.5%, the composition of the present invention will be blown off during high-speed processing, resulting in heater scum. be.
The high-speed drawing friction false twist processing agent of the present invention may be used for purposes other than the present invention, for example, as a spindle method false twist processing agent or before the drawing treatment of synthetic fiber spinning (including spin texture). I can't help it. As described above, according to the present invention, by coexisting polyether and two or more types of anionic antistatic agents in a specific combination, the trade-offs related to antistatic properties and heater scum are eliminated, and the product is stable and highly efficient at high speeds. False twisting can be performed. Next, the present application will be specifically explained with reference to examples, but the invention is not limited thereto in the least.
Note that in the examples, parts indicate parts by weight, and percentages indicate weight percent. Examples 1 to 5 and Comparative Examples 1 to 12 When polyethylene terephthalate was melt-spun at a spinning speed of 3300 m/min, the spun yarn was prepared in Table-1.
The pure adhesion amount was determined by using a water-based emulsion of the composition described in 1.
It was made to adhere at a concentration of 0.3% (by weight). The resulting 115 denier/36 filament undrawn yarn was stretched at a drawing ratio of 1.5 and at a heater temperature using a ceramic external friction false twisting device equipped with a 45 mm diameter disk.
220℃, friction disk rotation speed 6250r.pm, processing speed 700
False twisting was performed while stretching at m/min. The results are shown in Table-1. Status of scum generation on the heater The status of scum generation on the heater was determined by visual inspection of the amount of scum generated on the heater after 3 weeks of processing, and was graded from grade 5 to grade 1. Grade 5 (good) to grade 1 (poor). The presence or absence of smoke and tar was also determined during processing. Processing stability It was ranked into 5 grades: ○good, △, poor, ×poor, based on the amount of fluff generated during processing, yarn breakage rate, crimpability, etc. In addition, the components shown below were used for the components in [ ] [ ] and [ ] in the table.

[Table] From the above results, the following can be said. In the examples of the present invention, the amount of heater scum was small and the processing stability was sufficient. On the other hand, in Comparative Examples ~, heater scum increased and processing stability was insufficient. Furthermore, to explain the comparative examples in detail, the comparative examples ~ lack the component [] that is essential to the present invention, so the processing stability is extremely poor, and the heater scum is also defective because it is simply an effect of a small amount of anions. It was hot. In Comparative Examples ~, only a part of the polyether contained in Comparative Examples ~ was replaced with a nonionic activator, so heater scum further increased. In the comparative example, since the polyether was polyethylene oxide, heater scum increased, and it was clearly distinguished from the present invention. In the comparative example, the polyether of the present invention was changed to a low molecular weight polyether, but in this case, heater scum was reduced, but on the other hand, there was a lot of smoke, and the processing stability (workability) was poor.
It was also defective. In the comparative example, a part of the polyether of the example of the present invention was replaced with a nonionic activator, but heater scum increased. The comparative example had the same combination of ingredients as the present invention, but the amount of anions exceeded the upper limit of the present invention, resulting in a slight increase in heater scum. Further, in the comparative example, the anion was only the [ ] component, and in this case as well, almost the same results as the comparative example were obtained. In the comparative example, mineral oil or ester was used instead of polyether, so heater scum increased in a short period of time, making processing itself extremely difficult. As can be seen from the examples of the present invention as described above, it can be seen that there is an unexpected synergistic effect by combining component B [ ] and [ ] or [ ] and [ ] or [ ] and [ ] and [ ]. . Examples 6 to 8 When polyethylene terephthalate was melt-spun at a spinning speed of 3500 m/min,
The composition described in No. 2 was deposited using an aqueous emulsion at an emulsion concentration of 10% (weight) so that the amount of pure matter deposited was 0.25 to 0.4% and 0.60% (weight) or more. The obtained 78 denier/36 filament undrawn yarn was stretched using a circumscribed friction false twisting device equipped with a urethane rubber disc with a diameter of 45 mm and a hardness of 88° at a stretching ratio of 1.5 times, a heater temperature of 225°C, and a rotation of the friction disc. False twisting was performed while stretching at several 9,375 rpm and processing speed of 900 m/min. The results are shown in Table-2.

[Table] From the above results, the following can be said. Even with the treatment composition of the present invention, when the applied amount was in the range of 0.1 to 0.5%, heater scum was very small and processability was good, but when the applied amount exceeded 0.5%, heater scum tended to increase slightly. Examples 9 and 10, Comparative Examples 13 to 15 When polyethylene terephthalate was melt-spun at a spinning speed of 3500 m/min, the spun yarn was prepared in Table 3.
A composition as described in 1. was applied in an aqueous system at an emulsion concentration of 10% (by weight) so that the amount of pure adhesion was 0.3%. The obtained 78 denier/36 filament undrawn yarn was stretched using a circumscribed friction false twisting device equipped with a urethane rubber disc with a diameter of 45 mm and a hardness of 88° at a stretching ratio of 1.5 times, a heater temperature of 225°C, and a rotation of the friction disc. False twisting was performed while stretching at a processing speed of several 9375 rpm and 900 m/min. The results are shown in Table 3.

[Table] From the above results, the following can be said. In the example of the present invention, there was little heater scum and the processing stability was sufficient. On the other hand, in Comparative Examples, the molecular weight of the polyether component [A] was as high as 20,000, which resulted in increased heater scum and poor processing stability. A comparative example is a treatment agent proposed in Japanese Patent Publication No. 52-47079, but the anion component is 3%.
However, due to the lack of component [B]-[], both heater scum and processing stability were poor. A comparative example is a treatment agent proposed in JP-A-50-155796, but the anion component is 3%.
However, due to the lack of component [B]-[] and 10% nonionic activator, heater scum increased and processing stability was poor.
