Description

Synthetic fiber treatment oil and method of treating synthetic fiber by this oil agent

The present invention relates to an oil for treating synthetic fibers (hereinafter abbreviated as an oil agent) and a method for treating synthetic fibers by the oil.

)를 제조함에 있어서, 윤활성, 집속성 및 정전기방지성과 더불어 고도의 열처리히이터 오염방지능력(이하 내히이터 오염성이라 약기한다)을 발휘하는 유제 및 이 유제에 의한 합성섬유를 처리하는 방법에 관한 것이다.More specifically, sublimation processing of thermoplastic synthetic fibers such as polyester fibers and polyamide fibers

The present invention relates to an emulsion having high heat treatment heater contamination prevention ability (hereinafter abbreviated as heater contamination) as well as a method for treating synthetic fiber by the emulsion.

Recently, the manufacturing and processing of thermoplastic synthetic fibers is carried out to manufacture partialially oriented yarns (hereinafter abbreviated as POY) for the purpose of improving productivity due to hardening or process shortening. It has been proposed to manufacture the sublime construction by performing the sequential or simultaneous, and the speeding up has been further achieved. However, the speeding up has been more and more rapidly progressed up to now.

And as the speed is advanced, the emulsion used here

(I). Combustible yarns, especially stretchable combustible yarns, have high lubricity because they increase the speed or contact pressure of yarns that are in contact with various contact agents (e.g. rollers, guides, heat-treated heaters, disks, etc.). There is a need for an emulsion with focusing and antistatic properties.

屬)의 증가라든가 실에 대한 꼬임변형 작용의 상승에 의한 원심력의 증가등에 의해서 열처리 히이터상에서의 각종 탈락이 촉진되고, 또 필라멘트의 권축고정에 필요한 열량을 필라멘트에 공급하기 위하여 필연적으로 열히이터의 길이의 증대나 표면온도의 상승을 가져오게 되므로 탈락 성분이 더욱 열열화(熱劣化)되기 쉽다. 그리고 열처리히이터 표면에 열열화 성분(예를들면 타아르)이 퇴적되면 모우, 단사, 권축반(捲縮班) 등의 악영향이 발생한다. 이 때문에 그러한 탈락이 억제되고 내(耐)히이터 오염성이 우수한 유제가 요구되는 것이다.(II). The amount of thread per unit time passing through the heat treatment heater (

Iv) increase in centrifugal force due to the increase of twisting action on the thread, etc., to promote various dropouts on the heat treatment heater, and inevitably the length of the heat heater in order to supply the filament with the amount of heat required for crimping the filament This leads to an increase in the surface temperature and an increase in the surface temperature, so that the dropping component is more likely to be thermally deteriorated. When a thermal deterioration component (for example, tar) is deposited on the surface of the heat treatment heater, adverse effects such as wool, single yarn, crimp board, and the like occur. For this reason, such an drop-off is suppressed and the oil agent excellent in the contamination resistance of a heater is calculated | required.

)를 그때그때 정지시키고 히이터 표면을 청소하여 대처하고 있으므로 이 때문에 열효율의 손실, 청소인원 투입에 따른 성력화에의 역행, 생산효율의 저하 등을 초래하므로 이들이 해결되어야 할중요한 문제로 남아 있는 것이다.In order to smoothly perform the subsequent combustion process, an oil agent containing various compounds added to the spinning process has been proposed. However, as described above, the already proposed oil agent cannot fully cope with the increasingly severe combustible processing conditions. For example, the fact of the process regarding the heater contamination of the emulsion is unprecedented.

) Is stopped and then the heater surface is cleaned and coped, which causes the loss of thermal efficiency, the regression to the increase of labor due to the input of cleaning personnel, and the decrease of production efficiency.

In today's remarkable and rapid speed-up of combustible processing, the oil agent used therein is combined with heater pollution resistance, lubricity, converging property and antistatic property in order to sufficiently meet the requirements of (I) and (II). In general, it is essential that they are highly fulfilled as a whole.

Conventionally, as a means of improving the heat resistance in the heat treatment process of the supplier, it is important to improve the heat resistance of the oil agent itself imparted to the fiber, and various oil agents that do not deteriorate themselves and cause heater contamination have been studied. Enumerate as follows, but each has its drawbacks. First, mineral oils and fatty acid esters with respect to lubricants, which are the main components of emulsions, have defects in smoke resistance and anti-tartarization properties.

The ester compound (Japanese Patent Publication No. 50-53695) which introduced the quaternary carbon in the molecule, and the polyoxyalkylenated bisphenol which introduced the phenyl group in the molecule, and the ester of fatty acid and the horse (Japanese Patent Publication No. 53-43239, etc.) There is a flaw in anti-tararization.

Polydimethylsiloxane and its modified products (Japanese Patent Publication No. 58-12391, Japanese Patent Application Laid-Open No. 55-67075) are prominent in generating static electricity and have poor refining properties and poor compatibility with other emulsion components.

Modified silicones such as methylphenyl polysiloxane and polyepoxy siloxane (Japanese Patent Laid-Open No. 49-30621, Japanese Patent Laid-Open No. 51-67415) all use a large amount (amount exceeding 10% by weight) as an emulsion compounding ingredient. This creates insoluble sludge (Sludg e) that degrades itself on the heater surface. Therefore, the polyetherge compound (Japanese Patent Application Laid-Open No. 56-31077), which is currently recognized as the most useful lubricant among known compounds, has been subjected to this system due to the severe change of various treatment conditions accompanying the high speed in the combustion process as described above. Heater contamination also becomes a problem in the oil treatment agent, and it is pointed out that the degree of contamination becomes remarkable depending on the type and amount of the emulsifier or antistatic agent added thereto. Next, examples in which a small amount of antioxidant is added with respect to components other than such lubricants (JP-A-48-19500, JP-A-53-19500) can obtain some effects, but withstand high-speed processing conditions. can not do it.

Examples of adding a small amount of polydimethylsiloxane, methylphenylpolysiloxane, or polyepoxy siloxane (less than 10% by weight) are insufficient (Anti-Japanese Patent Office No. 54-5040, Patent No. 55-137273). And generally are not water soluble (as is the case for large amounts of use), and emulsifiers added to disperse these compounds in water as emulsion components are rather sources of heater contamination.

In addition, regarding the use of polyalkylene oxide-modified polysiloxanes with respect to components separate from lubricants, the example of using polyethylene oxide-modified polysiloxanes (JP-A-44-27518) still has sufficient resistance as a yarn oil for combustible processing. It does not have heater contamination.

An example in which linear organic polysiloxanes having a kinematic viscosity of 15 cst or more in combination with a polyether compound (Japanese Patent Application Laid-Open No. 48-5309) is an example of the example. Less durable against

An example of using polyalkylene oxide-modified silicone in addition to a large amount (35% by weight or more) by means of use with affinity polyalkylene oxide (Japanese Patent Laid-Open No. 50-59551) is a heater in the yarn of the modified silicone. Although it is intended to improve the defect of producing a sludge of white phase on the heater by reducing fallout into the phase, as described above, the increase in the flammable or stretched flammability rate gives a great centrifugal force to the yarns, so that the fiber It is very difficult to prevent the emulsion from being squeezed out from the surface.

The example in which a polyalkylene oxide modified polysiloxane and a reactive silicone compound are used in the ratio of the former / the latter = 5-400 / 100 parts by weight (Japanese Patent Laid-Open No. 52-96297) is 10% by weight of the modified polysiloxane as an emulsion component. When used above, an insoluble sludge, which deteriorates itself, is produced on the heater surface.

SUMMARY OF THE INVENTION The present invention provides an improved oil agent and a treatment method using the oil agent to solve the above-described defects of the book, and to satisfy the above-mentioned demands for high-speed processing, and to provide thermoplastic synthetic fibers such as polyester fibers and polyamide fibers. Emulsions and emulsions capable of exhibiting a high degree of heater resistance, lubrication, focusing and anti-static properties as a whole in high-speed manufacturing of sublime processing by performing drawing or sequential or simultaneous drawing and burning. It is to provide a method for treating synthetic fibers by.

As mentioned above, the present invention is also focused only on improving anti-tartarization of the oil agent itself, which is almost always imparted to the fiber as a means of improving the heater contamination resistance in the heat treatment process.

However, the inventors of the present invention have pursued a cause in which the contamination of the heater is a problem even in the polyether compound in which its own tartar is improved over the components of the other substrates described above. It is found that it contains a large amount of oligomer and a few polymers and these degradants which occur in itself, and the defoliant in the thread, such as the taricide, the oligomer and the polymer which is accompanied by the thermal deterioration of the emulsion itself, and It has come to the idea that only emulsions that simultaneously and highly alleviate these degradation products (taricides) can achieve industrially sufficient high speed of flammable or stretched flammables.

Thus, as a result of more intensive studies, it is necessary to apply specific modifications to the oil agent containing a predetermined amount of an antistatic agent and a lubricant to add a predetermined amount of polyalkylene oxide-modified polysiloxane having a limited molecular structure and molecular weight, as described above. It has been found that can be significantly reduced to the present invention has been completed.

In other words, the present invention relates to the following oil agents and methods of treating synthetic fibers with these emulsions, which can achieve high speed processing of synthetic fiber yarns which are progressing more and more rapidly in the industry today.

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

An integer that satisfies 8/2.

In addition, the repeating portion of the polydimethylsiloxane represented by X and the polyalkylene oxide modified siloxane represented by Y and the polyethylene oxide bound by a and the polyfuropropylene oxide bound by b and the repeating portion are repeated by a block or a random method. You may be.

The base oil is a lubricant mainly composed of polysulfuric compounds derived from alkylene oxides of 2-4 carbon atoms, as well as fasily oriented yarns of polyester fibers or polyamide fibers wound at 2,000-4,500 m / min. To a process oil emulsion containing 0.05-10% by weight of a polyalkylene oxide-modified polysiloxane having a molecular weight of 2,500 or more and 0.5-8% by weight of an anionic surfactant represented by the general formula (I). Characterized in that the treatment method of the fiber-containing fiber.

In the present invention, the polyalkylene oxide modified polysiloxane represented by the general formula (I) is added in a small amount as an essential component of the emulsion,

① Molecular weight is more than 2,500

② The number of repeating m of Y is 1-9

⑤ The number of repetitions of Y and the number of repetitions of X are m / ι = 1 / 100-45 / 100

As a result of satisfying all of the above requirements (1) to (5), the compound of the general formula (I) having undergone this specific modification is desired, and thus exhibits particularly significant heater contamination.

The lack of any of the requirements listed in formula (I) is not sufficient to achieve the object of the present invention.

For example, if the molecular weight is less than 2,500, the effect is less because it does not withstand the severe heat treatment conditions in the combustion process and does not form a stable oil film due to fuming or volatilization.

When m is 10 or more and ι is 19 or less, the polyether becomes close to the polyether and the dropping of the oligomer in the driving thread increases, so that only the same effect as in the case where this compound is not added can be obtained.

If ι exceeds 100, the performance will be similar to that of polydimethylsiloxane, leading to a decrease in the resistance to heater contamination, as well as to the formation of a varnish.

If a or b deviates from the electrical requirements, their own properties and compatibility with other emulsions will be inferior, resulting in insufficient effect as they do not form a uniformly stable oil film on the fiber surface.

Such a compound represented by general formula (I) is easily synthesized, for example, by a method such as hydrosyryl compound reaction between the compound of (i) and the compound of (ii).

(i) A compound obtained by methyl etherification, octyl etherification or acetylation of EO and PO adducts of aryl alcohol or the terminal hydroxy group.

(Ii) Methylhydrogen polysiloxanes with hydrogen atoms located in the random or block.

R is a mixture of CH ₃ and H, and is disposed in a random or block, and in the present invention, the anionic surfactant suppresses the amount of frictional charge generated in the traveling thread and leaks the generated charges quickly. For example, one or two or more kinds of sulfonate salts, sulfate salts, phosphate salts, or carbonates may be used, and any one having a hydrophilic group and a lipophilic group in the molecule and used as an antistatic agent may be the object.

Specific examples thereof include alkali metal salts or organic amine salts such as alkyl sulfonates and alkylbenzene sulfonates as the sulfonate salts, alkali metal salts or organic amine salts such as higher alcohol sulfates or polyoxyalkylene alkyl ether sulfates as sulfate salts. Examples of the phosphate salt include various natural alcohols, primary and secondary synthetic alcohols, and these alkylene oxide adducts. Examples thereof include alkali metal salts or organic amine salts of phosphates, and aliphatic monocarbonates and dicarbonates.

Among them, sodium, potassium, or alkanol amine salts having alkyl groups or alkenyl groups having 8 to 18 carbon atoms as lipophilic groups in the molecule are preferable.

Furthermore, in the present invention, the polyether compound, which is the main component of the lubricant as the base oil, gives good connection to yarns in the fiber manufacturing process, and shows excellent lubricating effect even under severe flammable conditions, and due to its own thermal deterioration. It is characterized by a small number of heater taricides and the like, and does not mean that the chemical structure is particularly limited, but an average molecular weight of 700 or more is preferable.

When the average molecular weight is less than 700, there is a tendency that the smoke resistance, the connection property, and the lubricity in the combustion or extension combustion process are lowered.

Specific examples include alcohols (saturated alcohols having 1 to 18 carbon atoms, oleyl alcohols, synthetic alcohols having 10 to 15 carbon atoms, reduced alcohols, monohydric alcohols such as hexadecanol, diols having 2 to 12 carbon atoms, glycerin and trimers). Polyhydric alcohols such as tyrol propane, alkylphenols, and the like), carbonic acids (such as caprylic acid, adipic acid, trimellitic acid), amine compounds (such as laurylamine, ethylenediamine, triethanolamine), thioether compounds or mer Ring-opening addition to captan compounds (thioglycol, triethylene glycol dimercaptan, etc.) and cyclic ether monomars, such as EO, PO, butylene oxide, or tetrahydrofuran, in the presence of a catalyst as a block or a lanthanum These may be polymerized, and these terminal hydroxyl groups may be etherified or silylated, and further, these two molecules of terminal hydroxyl groups may be condensed as formalization or cylylation.

As the lubricant component, it is also effective to use an ester compound and / or a mineral oil in addition to such a polyether compound.

These ester compounds and / or mineral oils are not particularly limited as long as they have substantially the effects as lubricants and frictional resistance lowering agents, but mono or diesters and polyesters of aliphatic alcohols and monohydric fatty acids in terms of the degree of effect and contamination resistance of the heater. Preference is given to mono or diesters of oxy (ethylene / furopropylene) aliphatic alcohols and monovalent or divalent fatty acids, and refined mineral oils having a Redwood viscosity of 40-200 seconds at 30 ° C, respectively.

The emulsion of the present invention is described above.

(A) polyalkylene oxide modified polysiloxanes and

(B) an anionic surfactant

(C) It is obtained by mix | blending in a specific ratio with the lubricating agent which makes a polyether compound the main component, and mix | blending these three components in a specific ratio will exhibit the desired synergistic effect.

By the way, (A) is 0.05-10 weight%, (B) is 0.5-8 weight%, and (C) is the remainder 82-99.45 weight%.

If (A) is less than 0.05% by weight, the effect may not be sufficiently exerted, resulting in increased tar tars of emulsions on the heater or origomers produced in yarns, decidants of polymers and their degradation products, while increasing 10% by weight. If exceeded, the insoluble sludge which deteriorates itself will generate | occur | produce, but it may cause the heater contamination.

In addition, when (B) is less than 0.5% by weight, various electric disturbances are caused, while when it exceeds 8% by weight, heater tar is increased.

In addition, the emulsion according to the present invention may suitably contain an emulsifier, a wetting agent, an anti-moulding agent, a rust preventive agent or the like in addition to the above-mentioned compounds.

Next, the processing method of the fiber by the oil agent demonstrated above is demonstrated.

狀)에 대한 유제실효성분으로서 0.2-1.0중량%정도이다.The emulsion of the present invention is applied to a synthetic fiber as a spinning oil to exhibit its effects. In use, the emulsion can be applied to an organic solvent solution or an organic solvent as a straight oil ring (straight oil ring). At this time, the adhesion amount of the emulsion to the synthetic fiber is usually

It is about 0.2-1.0% by weight as an effective tanning agent for i).

The object to which the oil agent of this invention is given is a synthetic fiber containing polypropylene, polyacrylonitrile, etc., and POY wound at the winding speed of 2,000-4,500m / min especially polyester or polyamide fiber In addition, when 0.25-0.7% by weight of the emulsion of the present invention is added, the effect of the object of the present invention is remarkably remarkable when it is subjected to flaming or stretching.

As described above, the emulsion of the present invention is prepared by blending the specific three components as described above in a specific ratio, and the synergistic effect makes it possible to obtain excellent comprehensive safety, especially heater pollution resistance, in high-speed manufacturing processing that is not present in conventional emulsions. It is.

The main factor of such a remarkable effect is that the improvement of the conventional emulsion only focuses on the reduction of the taring of the emulsion itself, but in the present invention, it is possible to reduce the dropping of the oligomer or polymer of the yarn tar which is a heater tar other than the emulsion. Moreover, there exists a point which prevented the thermal deterioration of the dropping material to a heater.

Hereinafter, the present invention will be described in more detail with reference to Examples and Comparative Examples, but the present invention is not limited thereto.

In addition, in the following description, an oil-forming composition ratio shows the weight% unless there is particular notice.
