Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an oil agent for treating synthetic fibers (hereinafter abbreviated as oil agent) and a method for treating synthetic fibers using the oil agent. This invention relates to an oil agent that exhibits a high degree of heat treatment heater stain prevention ability (hereinafter abbreviated as heater stain resistance) in addition to lubricity, cohesiveness, and antistatic properties when producing processed yarn, and a method for treating synthetic fibers using the oil agent. .

In recent years, the production and processing of thermoplastic synthetic fibers has focused on achieving improved productivity through labor saving and process shortening, and the company that manufactures partially orientated yarn (hereinafter abbreviated as POY) and POY. It has been proposed to produce bulky textured yarn by simultaneously or simultaneously carrying out drawing and false twisting using the method, and efforts are being made to further increase the speed of the process.
Such speed-up is currently progressing more and more rapidly.

As speeds increase, the oils used will also have to be affected by: 1) an increase in the speed of the yarn running in contact with various contacting bodies (e.g. rollers, guides, heat treatment heaters, disks, etc.) and contact pressure; In order to increase this, an oil agent is required to provide the false-twisting yarn, especially the drawn false-twisting yarn, with a high degree of lubricity, cohesiveness, and antistatic properties.

il) Due to an increase in the amount of yarn passing through the heat treatment heater per unit time and an increase in centrifugal force due to an increase in the twisting deformation effect on the yarn, various kinds of falling off onto the heat treatment heater is promoted.
In addition, in order to supply the filament with the amount of heat necessary for crimping and fixing the filament, the length of the heat treatment heater must be increased and the surface temperature must be increased, making it easier for the fallen components to deteriorate due to heat. When heat-deteriorating components (for example, tar) accumulate on the surface of the heat treatment heater, adverse effects such as fuzz, thread breakage, and crimped beds occur. Therefore, there is a need for an oil agent that suppresses such shedding and has excellent resistance to heater contamination.

Oil agents containing various compounds have already been proposed to be applied during the spinning process in order to smoothly carry out the subsequent false twisting process. However, such previously proposed lubricants are no longer able to adequately meet the increasingly severe false twisting conditions as described above. For example, the actual state of the process regarding heater contamination resistance of oil agents is that it is unavoidable to stop the machine every time and clean the heater surface. This has led to problems such as regression and reduced production efficiency, and these are important problems that need to be solved. Nowadays, the speed of false-twisting processing is rapidly increasing, and in order to fully meet the above-mentioned requirements 1) and il), the lubricant used for this process has properties such as resistance to heater contamination, lubricity, and cohesiveness. It is essential that the material as a whole has a high degree of satisfaction in terms of anti-static properties, etc.

Conventionally, as a means to improve the heat resistance in the heat treatment process of the supply system, it has been considered important to improve the heat resistance of the oil agent itself applied to the fibers, and to prevent the oil from deteriorating due to heat and contaminating the heater. Various types of oil agents have been studied, examples of which are listed below, but each has its own drawbacks.

First, regarding lubricants, which are the main components of oil agents, mineral oils and fatty acid esters lack smoke resistance and anti-tarring properties. Ester compounds with quaternary carbon introduced into the molecule (Japanese Unexamined Patent Publication No. 1983
-53695) and esters of polyoxyalkylenated bisphenols with a phenyl group introduced into the molecule and fatty acids (Japanese Patent Publication No. 53-43239, etc.) lack anti-tar properties.

Polydimethylsiloxane and its terminal modified products (Tokukō 5
No. 8-12391, JP-A No. 55-67075) generates significant static electricity and lacks scouring properties and compatibility with other oil components. Methylphenylpolysiloxane and polyepoxysiloxane (JP-A-49-30621, JP-A-51-
When modified silicones such as No. 67415) are used in large amounts (more than 10% by weight as a guide) as a component in the oil solution, they themselves produce thermally degraded insoluble sludge on the surface of the heater. Polyether compounds (Japanese Unexamined Patent Publication No. 31077/1983), which are currently recognized as the most useful lubricants among known compounds, have undergone severe changes in various processing conditions as the speed of the false-twisting process increases, as mentioned above. Therefore, heater contamination is a problem even in this type of processing oil, and it has been pointed out that the degree of contamination can become even more significant depending on the type and amount of emulsifiers, antistatic agents, etc. added.

Next, regarding components other than such lubricants, examples of adding a small amount of antioxidant (Japanese Patent Publication No. 48-17517, JP
No. 3-19500) has some effect, but cannot withstand high-speed processing conditions. Examples of adding a small amount (10% by weight or less as a guide) of polydimethylsiloxane, methylphenylpolysiloxane, or polyepoxysiloxane (Japanese Patent Publication No. 54-5040, JP-A No. 55-137273)
No. 3) have insufficient anti-tar properties and are generally not water-soluble (this also applies when large amounts are used), and the emulsifier added to disperse these compounds in water as an oil component can conversely become a source of heater contamination. 9-Also, regarding components other than lubricants that utilize polyalkylene oxide-modified polysiloxane, an example of using polyethylene oxide-modified polysiloxane (Japanese Patent Publication No. 44-27518
No.) has not yet achieved sufficient resistance to heater contamination as a raw yarn oil for false twisting. The example of using a linear organic borea xane with a kinematic viscosity of 15 cst or more together with a polyether compound (Japanese Patent Application Laid-Open No. 48-5309) is an example of this. Less is. An example of using polyalkylene oxide-modified silicone in a large amount (35% by weight or more) in combination with polyalkylene oxide with affinity (Japanese Patent Application Laid-Open No. 50-59
No. 551) attempts to reduce the shedding of the modified silicone from the yarn onto the heater, thereby improving the drawback that the modified silicone itself produces white stains on the heater. Since an increase in the twisting or drawing false-twisting speed exerts a large centrifugal force on the yarn, it is extremely difficult to prevent the oil component from being squeezed and shaken off from the fiber surface by physical means. An example of using polyalkylene oxide-modified polysiloxane in combination with a reactive silicone compound at a ratio of 5 to 400/100 parts by weight of the former/latter (Japanese Patent Application Laid-open No. 52-96297) shows 10 parts by weight of the modified polysiloxane as an oil component. % or more will produce an insoluble sludge on the heater surface, which itself is thermally degraded.

The present invention provides an improved oil agent and a processing method using the oil agent that eliminates the conventional drawbacks of sloping, etc. and meets the above-mentioned requirements for high-speed machining. When producing bulky textured yarn at high speed by false twisting or sequentially or simultaneously drawing and false twisting the fibers, high resistance to heater staining,
The present invention provides an oil agent that can comprehensively exhibit lubricity, cohesiveness, and antistatic properties as a whole, and a method for treating synthetic fibers using the oil agent.

As mentioned above, even today, most of the methods for improving resistance to heater contamination in heat treatment processes focus only on improving the anti-taring properties of the oil itself applied to fibers. It's dark. However, we have found that even in polyether compounds whose own tarring is improved (as compared to the other base components mentioned above),
As a result of investigating the cause of the problem of heater contamination, we found that the sludge that accumulates in the heat treatment heater contains not only degraded oil but also a large amount of oligomers and some polymers generated from the running yarn itself and these thermally degraded products. The company discovered that it simultaneously and highly reduces tar compounds that accompany the thermal deterioration of the oil itself, as well as oligomers, polymers, etc. that fall off from threads, and their degraded products (tar compounds). We have arrived at the idea that only the obtained oil agent can sufficiently achieve high speeds of false twisting and stretch false twisting on an industrial scale. As a result of further intensive research, we found that a predetermined small amount of polyalkylene oxide-modified polysiloxane with a limited molecular structure and molecular weight that had undergone specific modification was added to an oil containing a predetermined amount of antistatic agent and lubricant. However, they have discovered that the above-mentioned heater sludge can be significantly reduced, and have completed the present invention.

That is, the present invention relates to an oil agent and a method for treating synthetic fibers using the oil agent, each of which is capable of extremely smooth industrially high-speed processing of synthetic fiber threads, which is progressing more and more rapidly these days.

A lubricant whose main component is a polyether compound derived from an alkylene oxide having 2 to 4 carbon atoms is used as a base oil, and the average molecular weight represented by the following general formula (I) is 2.
An oil agent for treating synthetic fibers comprising a polyalkylene oxide-modified polysiloxane of 500 or more in an amount of 0.05 to 10 parts by weight and a hereditary ionic surfactant in an amount of 0.5 to 8 parts by weight.

In addition, a repeating portion of polydimethylnoxane represented by X and polyalkylene oxide-modified siloxane represented by Y, and a repeating portion of polyethylene oxide represented by a and polypropylene oxide represented by b. may be repeated in either a block or random manner. ] C-Shary of polyester fibers or polyamide fibers wound at a winding speed of 2000 to 4500" l/min
A lubricant containing a polyether compound derived from an alkylene oxide having 2 to 4 carbon atoms as a base oil is added to the oriented yarn, and the above general formula (I) is applied.
Applying a processing oil containing 0.05 to 10% by weight of a polyalkylene oxide modified polysiloxane having an average molecular weight of 2500 or more and 0.5 to 8% by weight of a hereditary ionic surfactant. Characteristic synthetic fiber processing method.

In the present invention, the polyalkylene oxide-modified polysiloxane represented by the general formula (I) is added in small amounts as an essential component of the oil agent; ■The alkylene oxide chain in Y is a repeating block or random of ethylene oxide (hereinafter abbreviated as EO) and propylene oxide (hereinafter abbreviated as PO), and ■The number of repeats a of the EO and the number of repeats of the PO. is 15≦a0b≦80
And Tsu2/8≦b/a≦8/2, ■Number of repetitions of Y? n and
5/100, which satisfies the requirements of ■～■ above,
The compound of general formula (1) subjected to such specific modification exhibits the desired effects, particularly remarkable resistance to heater staining. General formula (I) K Even if any of the additional requirements are lacking, the object of the present invention cannot be fully achieved. For example, if the molecular weight is less than 2,500, it will not be effective because it will not be able to withstand the severe heat treatment conditions in the false-twisting process, will smoke or volatilize, and will not be able to form a stable oil film. When nl is 10 or more or t is 19 or less, the properties are similar to that of polyether, and oligomers often fall off from the running yarn, resulting in only the same effect as when this compound is not added. . When t exceeds 100, perhaps because the performance becomes similar to that of polydimethylsiloxane, not only the heater contamination resistance decreases, but also the composition itself becomes a festival fall item. If a+b deviates from the above requirements, a sufficient effect cannot be obtained, probably because a uniform and stable oil film is not formed on the fiber surface due to its own properties and reduced compatibility with other oil components.

Such a compound represented by the general formula (I) can be easily synthesized, for example, by a method such as a hydrosilylation reaction between the following compound and the compound 11.

1) Terminus of EO and po+1 adducts of allyl alcohol (
ω-position) A compound in which the hydroxy group is octyl etherified.

11) Methylhydrodienepolysiloxane having hydrogen atoms located randomly or in blocks.A mixture of CH3 and H, which are arranged randomly or in blocks.

In addition, in the present invention, the anionic surfactant suppresses the amount of triboelectric charge generated on the running yarn and quickly leaks the generated charge, and is an anionic surfactant such as a sulfonate salt, a sulfate salt, a phosphate salt, or a carboxylic acid salt. Although one species or two or more species may be used, any one having a hydrophilic group and a lipophilic group in the molecule and used as an antistatic agent can be targeted. Specific examples include alkali metal salts or organic amine salts such as alkanesulfonates and alkylbenzenesulfonates as sulfonate salts, alkali metal salts or organic amine salts such as higher alcohol sulfates or polyoxyalkylene alkyl ether sulfates as sulfate salts, and various phosphate salts. Natural alcohols, primary or secondary synthetic alcohols, alkali metal salts or organic amine salts of phosphates such as alkylene oxide adducts thereof, and carboxylic acid salts include aliphatic monocarboxylic acid salts and dicarboxylic acid salts. Among these, an alkyl group having 8 to 18 carbon atoms or an alkenylium, potassium or alkanolamine salt as a lipophilic group in the molecule is preferable.

Furthermore, in the present invention, the polyether compound, which is the main component of the lubricant that serves as the pace oil, provides good cohesiveness to the yarn during the fiber manufacturing process and exhibits an excellent lubricating effect under severe false twisting conditions. It has features such as less generation of heater tars due to thermal deterioration of itself, and although its chemical structure is not particularly limited, it is preferably one with an average molecular weight of 700 or more. If the average molecular weight is less than 700, smoke resistance, cohesiveness, and lubricity during the false-twisting or stretch-false-twisting process tend to decrease. Specific examples include alcohols (monohydric alcohols such as saturated alcohols with 1 to 18 carbon atoms, oleyl alcohol, synthetic alcohols with 10 to 15 carbon atoms, reduced alcohols, hexadecanol, etc.).

Diol having 2 to 12 carbon atoms. Polyhydric alcohols such as glycerin and trimethylolpropane. alkylphenols, etc.), carboxylic acids (capric acid, adipic acid, trimellitic acid, etc.), amine compounds (laurylamine, ethylenediamine, triethanolamine, etc.), thioether compounds or mercaptan compounds (thioglycol,
triethylene glycol dimercaptan, etc.), EO,
There are products in which cyclic ether polymers such as PO, butylene oxide, or tetrahydrofuran are subjected to block or random ring-opening addition polymerization in the presence of a catalyst, and their terminal hydroxy groups are etherified or silylated. There are also compounds in which the terminal hydroxy groups of these two molecules are condensed by formalization or silylation.

It is also effective to use such a polyether compound in combination with an ester compound and/or mineral oil as a lubricant component. These ester compounds and/or mineral oils are not particularly limited as long as they have a substantial effect as a lubricant/frictional resistance reducing agent, but in terms of the degree of effect and resistance to heater contamination, Mono- or diesters of polyoxy(ethylene/propylene) fatty alcohols and mono- or divalent fatty acids, redwood viscosity at 30°C of 4
Refined mineral oils of 0 to 200 seconds are preferred.

The oil agent of the present invention is made by blending the above-described ◎ polyalkylene oxide-modified polysiloxane and ◎ anionic surfactant into a lubricant whose main component is ◎ a polyether compound. By blending the three components in a specific ratio, the desired synergistic effect can be achieved. Therefore, ■ is 0.05 to 10% by weight, ■ is 0.5 to 8% by weight, and ◎ is the remaining 82 to 9945%.
Weight%. If (2) is less than 0.005% by weight, the effect will not be sufficiently exhibited, and the amount of oil tars on the heater, oligomers and polymers that may generate threads, and their degraded products will increase; If it exceeds %,
Insoluble sludge, which itself has deteriorated due to heat, is generated and causes contamination of the heater. Furthermore, if ■ is less than 0.5% by weight, various electrical problems will occur, while if it exceeds 8 times, heater tar will increase.

Incidentally, the oil agent according to the present invention may appropriately contain an emulsification regulator, a wetting agent, a fungicide, a rust preventive agent, etc. in addition to the above-mentioned compounds.

Next, a method for treating fibers using the oil agent described above will be explained. The oil agent of the present invention is applied to synthetic fibers as a spinning oil agent and exhibits its effect, but when used, it may be used as an aqueous emulsion, as an organic solvent solution, or as an oil agent (straight oiling).
can be added to synthetic fibers. At this time, the amount of the oil agent attached to the synthetic fiber is usually about 0.2 to 10% by weight based on the amount of the oil agent's effective components based on the thread.

The oil agent of the present invention can be applied to synthetic fibers containing polypropylene, polyacrylonitrile, etc., but in particular polyester and polyamide fibers are to be applied.
P that is wound at a winding speed of 2000 to 4500 m7 minutes
When the oil agent of the present invention is applied to OY in an amount of about 0.25 to 0.7 weight percent, and then subjected to false twisting or stretch false twisting, the effects aimed at by the present invention are extremely noticeable.

As explained above, the oil agent of the present invention is made by blending the three specific components mentioned above in a specific ratio, and due to their synergistic effect, it has excellent overall stability for high-speed manufacturing and processing, which is not found in conventional oil agents. In particular, it is possible to obtain a rigid heater contamination resistance. The main reason for this remarkable effect is that conventional oil agents have been improved only by reducing the tar formation of the oil agent itself, but in the present invention, the heater tar constituents other than the oil agent, such as oligomers in the threads and This also reduces the amount of polymer falling off, and prevents thermal deterioration of the falling material on the heater.

Hereinafter, the present invention will be explained in more detail with reference to Examples and Comparative Examples, but the present invention is not limited thereto. In the following description, the composition ratio of the oil agent is hereditary unless otherwise specified.
