Description

DETAILED DESCRIPTION OF THE INVENTION The present invention provides a spinning oil for polyester suitable for high-speed spinners.The purpose of the present invention is to improve the cohesiveness of fibers to make the spinning properties more suitable, and to improve the temperature and humidity. It tends to increase roller wrapping due to changes in temperature, especially under high temperature and high humidity conditions, and has excellent antistatic properties.It also prevents white powder scum and oligomers from falling off due to damage to twill lines during the spinning process. It is an object of the present invention to provide a polyester twill spinning lubricant aimed at reducing spinning scum and minimizing process troubles.

In the spinning industry, such as hebe and synthetic textiles, efforts are being made to save labor in order to reduce processing costs, and a spinning oil suitable for high-speed spinning is desired. Textile oil has not yet appeared, while 1 Synthesis 111
61 has a smoother surface than cotton or wool, so the conventionally used oil agent 1 does not pass through the spinning process well, resulting in cylinder winding in carded potatoes, islands, or streaks. In this era of energy saving and modern times, things like winding around the earth will occur.
Due to the problem of easing lll1 conditions, there is a strong desire for a spinning oil agent that is sensitive to temperature control conditions and environmental changes.

In general, the well-known spinning oil such as Synthetic 11JIII is usually a blended oil that has both smoothness and anti-fatty properties. The smoothing components include animal and vegetable oils, mineral oils, fatty acid ester compounds, or nonionic activators consisting of ethylene oxide, propylene oxide, or adducts of both fatty acid esters of aliphatic higher alcohols or polyhydric alcohols. On the other hand, antistatic agents include alkyl sulfonates, furkyl sulfates, and alkyl amines. - Cationic activators such as ethylene oxide adducts, quaternary ammonium salts or amphoteric activators of the alkyl betaine type are used. These components are usually combined and used as a spinning oil. However, it is generally known that nonionic surfactants, animal and vegetable oils, mineral oils, or fatty acid esters used alone or in combination mainly increase the friction between the 111 lines and the thin wire and improve the cohesiveness. Adhesive substances may adhere to the goa roll or metal seal in the case of open iron or filament 1, and the stickiness of the oil may cause curling, or Otherwise, it will worsen the antistatic properties and increase troubles in the spinning process.

On the other hand, anionic activators are generally used as alkali metal salts, and many have good antistatic properties, but their properties change significantly with changes in temperature and humidity, and the viscosity of the oil agent itself is low at low humidity. Therefore, it is well known that the winding on the roller is small, but the winding on the high keg side rapidly increases the winding on the roller, which causes spinning troubles. In addition, cationic activators generally have excellent antistatic properties, and are known to have excellent antistatic properties even at low humidity; however, due to their high hygroscopicity, they are very susceptible to changes in humidity (at high temperatures). ---
This will cause curling. It is also known that the amphoteric activator has the disadvantage of causing rust on the metal parts of spinning machines.
Similar to cationic activators, it is known to have drawbacks such as high humidity, resulting in roller wrapping and yellowing of the fibers when heated.

On the other hand, alkyl phosphate salts have come to be used because they have relatively good spinnability.

This alkyl phosphate is usually an alkali metal salt (!F
It is used as a potassium salt in #, and has high antistatic performance, moderate smoothness, excellent extreme pressure action, and has advantages such as less roller wrapping under narrow temperature and humidity conditions. Due to its well-known properties, it has recently become an important component of textile oils. However, although alkyl phosphate salts have these advantages, they are somewhat insufficient in antistatic properties at low humidity, have poor fiber cohesiveness, and are not as effective as other 7-ion surfactants. Similarly, it also has the disadvantage that its properties change greatly at high temperatures and its stickiness increases, increasing the amount of winding during the spinning process.Therefore, while taking advantage of these advantages of alkyl phosphate salts, at the same time Textile oils with improved drawbacks are highly desirable, and attempts at improvements toward this end have been pursued from the alkyl phosphates themselves and from oil formulation partners containing alkyl phosphate salts.

Techniques for improving alkyl phosphate salts include 1, for example, flukyl phosphate 27!, which is synthesized from a synthetic alcohol with a side chain to which polyoxyethylene is added. -) (Special public r
iss o - mo1ss issue newsletter), an alkyl phosphate metal salt C in which the average carbon number of the alkyl group is 12 to II and the normal content in the furkyl group is 60 to 90%.
4I Association No. 1988-31918), methyl-decomposed alkyl phosphate salt C% (see 1988-1g No. 5 newsletter) (see Japanese Publication No. 42-11480), etc. are known. However, although these furkyl phosphate salts of the disclosed technology improve the antistatic performance and the convergence of 111 sheets, on the other hand, they tend to increase adhesion or produce significantly excessive white powder scum during the spinning process. Its improvement is still insufficient, as the drawbacks are at the same time more amplified. As described above, it is currently considered difficult to obtain a spinning oil agent that can meet the recent spinning conditions that require high performance only by improving the alkyl phosphate salt itself.

Therefore, attempts have been made to improve the conventionally known furkyl phosphate salt or improved alkyl phosphate salt using a compounding oil technology in which other surfactants are used in combination.
Although this technology depends on the formulation and composition, it is possible to compensate for the drawbacks of alkylphos-7-ethyl salts by using other ingredients such as surfactants, so it is more commonly used than the method of improving only alkylphos-7-ethyl salts. It is excellent.

Examples of disclosed omniscient technologies of this type include the following.

Japanese Patent Publication No. 1983. -141761 publication discloses an oil agent that uses a combination of N-acylsulfucinate and a phosphate surfactant;

It has been found that winding, white powder scum in spinning I1, and other process troubles have not been reduced to completely satisfactory levels.

Against this background, the present inventors aimed to develop a spinning oil that has high convergence, low scum, and low temperature/humidity dependence while achieving the high speed and high efficiency that are the objectives of the present invention. As a result of extensive research, we have developed an oil that has unprecedented effects.

That is, the present invention provides cetyl phosphate potassium fs

This is a polyester #miscellaneous spinning oil agent characterized by the following.

The background on which the present invention was made will be described below.

Conventionally, in a composition containing an alkyl phosphate salt as a lubricating agent for polyester raw material 1, the alkyl phosphate salt used as described above has a carbon number of SZ.
It has a relatively long alkyl group with a relatively long degree of carbon, and most of them have potassium lauryl phos7ate as the main component. , the alkyl chain changes from unsaturated or branched to straight chain saturated 1, the moisture absorption rate of the alkyl phosphate salt itself decreases, the properties change to become more homogeneous, and the change in properties due to changes in temperature and humidity also decreases. , Similarly, in terms of spinnability, as the dampness decreases, the antistatic property deteriorates, and as the properties become more homogeneous, the disadvantages of convergence and coiling 7 ohm deteriorate.
On the other hand, it has the characteristics of being strong (and insensitive to changes in temperature).

At the same time, the spinner's II also has the advantage of having fewer m-wrap and adhesion troubles even under white powder conditions or high temperatures. Straight-chain saturated carbon atoms with a specific length of ~1 Alkyl phosphate salts, such as potassium cetyl phosphate, have been not used as a main component of spinning oils for polyester fibers because they have too many of the above-mentioned drawbacks.1 For example: JP-A-5S-142Tli
This can be easily understood from the examples of Publication No. 1, Bulletin No. 4111@5s-142771, and Bulletin No. 77 of Special Publication No. 18/1982.

To explain this point in detail, JP-A-55-142
In the comparative example of Bulletin No. 768, an oil agent containing potassium cetyl phosphate as the main component and polyethylene glycol monolaurate with 300 molecular weight additions of bolierene gellicol was used. is cetylphos 7 ethka □At
Oil compositions containing polyoxyethylene lauryl ether as the main component and 2 moles of polyoxyethylene added thereto are shown, but as shown in the comparative example, the spinnability of these oil compositions is poor in antistatic properties and focusing properties. It has been evaluated as not good.

On the other hand, an oil agent containing polyethylene glycol dilaurate with a molecular weight of 1600 added with polyethylene glycol dilaurate with SO% or more and the remainder being potassium cetyl phosphate is also available at 4m-11127? It is described in the example of the issue report.

(In addition, it is stated that an oil agent containing 100% potassium cetylphosphate causes the wrap to tighten, that is, it has poor focusing properties.) However, in the association, the content of potassium cetylphosphate exceeds 50% There is no description of the composition of the oil agent, and furthermore, the technical explanation in this publication is only about polyethylene glycol dilaurate, and there is no mention of the blending effect, technical role, or content of cetyl phosphate.

On the other hand, %opening 11!1S-1! ? In Publication No. 070,

Therefore, preferably ~1 alkyl phosphate calic^ is 'F!-'J-kyk sulfate with a blending ratio of mono; di; polyphosphate of 40 to 60: s s to t s : 2 to t o. It is described that it is neat potassium, but what is the purpose of the surface treatment agent disclosed therein?

Hydrophobic synthetic materials are used for oils that require hydrophobicity, materials for hoses, and sanitary materials such as diapers and napkins.
When providing c., the hydrophobicity (water absorption rate) of the hydrophobic synthetic fiber
The objective of the present invention is to maintain the quality of the spinning oil, and is not intended to improve the spinning oil, which is the object of the present invention. It is clear from the examples. All of the surface treatment agents in the examples were composed of potassium alkyl phos7ate alone, and even if such surface treatment agents were attached to polyester fibers and passed through the spinner Sk, the cohesiveness would be poor. It is clear that good spinnability at the level targeted by the present invention cannot be obtained as a result of extremely insufficient coiling or deterioration of the coiling form. It is stated that polyethylene Tele 7 Talley F raw cotton treated with Table 1iJa coral consisting of the above-mentioned specific cetyl phosphate alone showed good millability in cardle spinning knees.

However, it is a matter of course that the spinnability of Kakar raw cotton is not good in normal spinning Hy such as polyester WI fiber alone or polyester WI fiber and other stirrup anchors (e.g., cotton, lace, wool, etc.). Furthermore, it is stated in the publication that other components can be mixed with the potassium furkyl phosphate in the publication; however, in the spinning oil, furkyl phosphate F and other surfactants are It is well known to those skilled in the art that any combination is not necessarily precious, and that there are considerable limitations not only in the species SL of furkyl phosphate itself, but also in the types and blending ratios of other components used in combination. This is where I am. Therefore, the surface treatment agent of the experimental publication, which uses alkyl phosphate □Calic^ in combination with RengerJ et al.
Even if it is used as a spinning oil for wire, the high level of spinning performance that is the objective of the present invention cannot be obtained.

However, the inventors of the present invention have intensively studied various types and combinations of long-chain alkyl phosphate salts and other ingredients mixed therein, and have found that they have solved the drawbacks of cetylphos-7acepotassium and also lost its advantages. This led to the discovery of extremely limited agent and oil formulation technology. That is, the main component is cetyl phosphate alone, which has a predetermined average number of carbon atoms in the alkyl group, and contains a limited amount of a selected specific type of nonionic agent. The oil composition is
Compared to conventional oil compositions, p-roller rolling and 4I's roller rolling under high temperature conditions are greatly reduced, and white powder scattering is also greatly reduced! It also provides good antistatic properties and good focusing properties, which is the objective of the present invention as described above.

Here, the components blended with potassium furkyl phosphate can exhibit excellent spinning characteristics only if they are very determined to 5 and 10, similar to the potassium furkyl phosphate used in the present invention. In other words, in general, any combination of furkyl phosphates and other active agents is not acceptable; rather, it depends on the type of alkyl phosphate itself as well as the type and blending ratio of the surfactant used in combination. It is known that there are limitations.

Moreover, there are no general rules regarding the combination of surfactants used in conjunction with phosphates, and even though it is a compounded oil, it is necessary to perform bone quality measurements and spinning tests to determine its quality as a single type of oil. The current situation is that it must be done. In other words, the types of alkyl phosphates, surfactants and other drugs to be blended, and J&L#c have no additive properties in terms of q# properties, so -M1Lkc each has excellent properties when used alone. Even if they are combined, their characteristics are rarely exhibited, and vice versa.

Next, I will specifically explain the book 'AIJl. First, the potassium furkyl phosphate of the present invention contains potassium cetyl phosphate in an amount exceeding 50% by weight.

And the average IR prime number of the furkyl group in the whole is ttS~
17.5 can be used. The ratio of cetylphos-7acecadaum in potassium alkylphosphate and the average number of carbon atoms of the alkyl group in potassium furkylphosphate AK are important, and if the ratio of potassium cetylphosphate is 50% by weight or less or the average number of carbon If it is less than 1411, the adhesive of the oil itself will be large and the properties will change greatly with a 1lfi degree change, resulting in white powder scum and roller winding during the spinning process.
On the other hand, if the average coal jI number exceeds 1'7.5, the antistatic properties or the cohesiveness of the raw cotton may be insufficient, or the aqueous solution may When this happens, the stability of the solution becomes poor, and it is no longer possible to obtain satisfactory spinning properties.

In the present invention, the ratio of cetylphos 7A F potassium lime in alkylphos 7A F should be 50% by weight;
A) Although the desired effect of the present invention can be obtained even at ZGo% weight %, the ratio at which the desired effect of 4IK main feathers can be exhibited is within the range of 60 to 60 weight %. The reason why 4Hc can exhibit the desired effect of the present invention in III with a ratio of 60 to $0% by weight compared to when F is composed of cetyl phosphate alone has not been fully elucidated; -F
It is thought that mutual effects occur due to the coexistence of potassium.

Such reciprocal effects are recognized in alloys used in IC in the metal industry and in polymer applications in polymers. In the present invention, one example of potassium cetyl phos7ate that can be contained in the potassium alkyl phosphate is sauce, although there is no limit thereto.

Although there is no problem in the distribution of lower or higher alkyl groups, the potassium alkyl phosphate has an average carbon number of ttS to 11.5. In this case, the alkyl group may be either a saturated chain, 0 branched chain, or an unsaturated chain, but the saturated chain is preferably 411C to 1°.The potassium furkyl phos 7ate of the present invention can be obtained by a known method.For example, A method of reacting furfur with a straight chain or side chain with Pt(%) and neutralizing the resulting reaction product with potassium hydroxide, or a method of reacting furfur with a straight chain or a side chain with POCl. It can be obtained by reacting and neutralizing the resulting reaction product with potassium hydroxide.It can also be obtained by combining the thus obtained alkyl phosphate potassium A with ?1&.

Note that the average number of carbon atoms in the alkyl group of potassium 5-alkyl phosphate heptaate is the weight average value of each alcohol contained in the raw material alcohol used for the synthesis of the alkyl phosphate, based on the carbon number of the furkyl group. For example, the raw material Alpur is 60% by weight of heptylphos7ate calicum whose furkyl group has an enzymatic number of 16, 20% by weight of lacryl alcohol whose furkyl group has 12 carbon atoms, and stearyl whose furkyl group has a carbon number of 18''r! Alpur and.

If each contains 10% by weight of oleylalpour, its average carbon number is (16
11Xa Ri! It becomes 1 line @. As raw alcohol, 1
synthetic alcohol.

Known alcohols such as natural alcohols can be used. In general, the average carbon number of the raw material alcohol and the average carbon number of the alkyl group in the alkyl phosphate synthesized using it are substantially the same, so the average carbon number of the alkyl group in the present invention is: Raw material Alpur & not.

Naturally, this also applies to alkyl phosphates synthesized from it. Examples of raw alcohols that can be used in the present invention include Calcol 60° Calcol goC or higher, Kao Seiken Co., Ltd. 11), Alfol 1, Alfol tall, Alphor 1sgor or higher, manufactured by Continental Oil Company), etc.

In alkyl phosphate salts, the length of the alkyl group is 0.
It is well known that the properties of alkyl phosphate salts and, in turn, the spinnability of oils containing them, vary greatly depending on the type and distribution thereof or the type of salt.

The degree of phosphorylation and acid value are also important. Strangely, however, there is no literature available regarding the importance of the degree of phosphorylation or acid value on the properties or spinnability of alkyl phosphate salts. ,・For example, JP-A-54-Is@893 Kinho k
It is posted on le. Starting from using alkyl phos7ate potassium with appropriate IIH phosphorylation degree and acid value,
The degree of phosphorylation of potassium furkyl phos7ate in the present invention is α5 to 1.0 to achieve the desired effect of the present invention.
O1 is preferably in the range of α6 to αS, and the acid value is in the range of O to SO, preferably 20 to 40. If the degree of phosphorylation is outside the scope of the present invention, the spinnability may deteriorate overall.

If the stability of the aqueous solution deteriorates or the acid value is outside the range of the present invention, antistatic properties may be insufficient, focusing properties may deteriorate,
Otherwise, the tackiness may increase or the stability of the obtained aqueous solution may become insufficient, which is undesirable.

1 In the present invention, the degree of phosphorylation refers to the number of moles of phosphorus bound to 1 mole of alcohol used, based on the phosphorus content (C weight) obtained by the phosphomolybdic acid colorimetric method based on the well-known phosphorus quantitative analysis method. The degree of phosphorylation is determined by calculating whether the acid value Titrate and determine the acid value from the titration value.

In other words, an acid value of O means complete neutralization.
The acid value SO indicates that the potassium salt of the alkyl phosphate ester is half neutralized.

Furthermore, alkyl phos7ate potash^ generally contains mono-, di-, and polyester phosphates;
In lI, the ratio of mono, di, and polyester is @i
c In general, monoesters have higher hygroscopicity and slightly higher adhesiveness than di- and polyesters, but they also have good antistatic properties or focusing properties, and are easily soluble in water, so the monoester ratio is The spinnability changes depending on the size of the yarn.6 The monoester ratio that can best exhibit the intended effects of the present invention is within 40% by weight.

Note that the monoester ratio here is determined as follows. After making a water-containing Bouville alcohol solution of potassium alkyl phos 7ate and passing it through a cation exchange resin, α1
Potentiometric titration is performed using a specified NaOHill solution, and the monoester ratio is calculated from the titration value.

In the case of an unspecified invention, even if other requirements are set to the uninvented range, satisfactory antistatic properties or focusing properties cannot be obtained.

On the other hand, if it exceeds 1500, good spinning properties cannot be obtained either because the cohesiveness is insufficient or the number of roller wraps increases.

- dilaurate ξ lystate and the like. Of course, in the present invention, a plurality of polyethylene glycol sialylates can be used within the scope of the present invention.

The present inventor, Hiro, has conducted a detailed study on the bulk properties, aqueous solution stability, spinning properties, etc. of blended oils containing potassium flukyl phos 7ate and numerous components of different types, types, and structures. This is what led us to select the limited polyethylene dalyfur dialkylate of the present invention as a component to be combined with the potassium flukylphos 7ate of the invention.According to the studies of the present inventors, anion as a component to be combined. Surfactants, cationic surfactants, or amphoteric surfactants tend to be used for roller wrapping, white powder scum, or convergence points, and mineral oils and smoothing agents for synthetic lubricated steel parts tend to be insufficient in terms of antistatic properties. and, in general, nonionic surfactants tended to be more favorable for the purposes of the present invention than their counterparts.

The present inventors conducted a more detailed study on nonionic surfactants, and found that the types of nonionic surfactants include furkyl ether type, alcoholic phenol ether type, and m-fatty acid ester! 1. Alkylamine 11. There are alkylardo type, polyalcohol fatty acid ester type, polyhydric alcohol ether type, and copolymer type of polyethylene glycol and polybupylene glycol.

As a result of intensive study on these issues, we have developed focusing properties, anti-static properties, M attachment, white powder scum, and coiling form.

There are many nonionic surfactants that satisfy individual properties such as water fII liquid stability (for example, antistatic properties), but there are none that satisfy the IJI properties in general. Among the fatty acid ester type, there was only the sialylate of polyethylene glycol with a molecular weight of sOO~1500, which is the diester type. Even if it is blended with potassium 7ate, it is not possible to obtain as good and balanced spinnability as the oil rope composition of the present invention shows. In other words, it is a unique composition in an extremely narrow -1 region, and the unique point of such a composition can only be discovered through numerous and detailed studies.

In addition, the sialychelate of polyethylene glyfur is
It is represented by the following formula: % (where R and R' are alkyl groups, and D is a positive integer). In addition, in the present invention, the number of carbon atoms in the alkyl group of the full chelate is represented by R+1 or R'+1, and the average number of carbon atoms is (R+1)+(R'+1
) 2. Preferably R and R' are the same, but different C4 is acceptable.

Next, the composition ratio of unreleased WAK will be explained.

First, the potassium flukylphos 7ate of the present invention is present in the oil composition in an amount of 7O-IS weight.

and the polyethylene glycol silacrate of the present invention is 1
It is essential that it be added in an amount of ~30% by weight. The proportion of potassium alkyl phos7ate in the oil composition is 1.
If the weight percent is unfinished, it is not preferable because it increases roller winding, especially one-roll winding under high temperature and high humidity, increases white powder scum, or deteriorates antistatic properties.

When the ratio exceeds about 95% by weight (polyethylene glycol sialylate is less than about S%), the focusing property deteriorates as the composition ratio of potassium furkyl phosphate increases. Alkyl phosphe-F potassium is about 7
PoV ethylene dialkylate is about 5 to 9% by weight.
Only in the range of 30% by weight, spinnability is good over the entire spinner pattern, and the object of the present invention can be achieved.

The amount of the oil of the present invention deposited on Bomaester IIIMK is:
aOS ~ (L4% by weight, preferably a1 ~ a! Valuable%. If the amount of adhesion is less than this, static electricity is likely to occur due to adhesion spots (and the amount of adhesion is less than this). If the number is higher than the range, the tackiness will increase and there will be a tendency for spinning scum to increase and the number of 1 attachments to increase.

The oil agent of the present invention can be diluted with water to form an aqueous emulsion, and can be applied to tow and cut laK in spinning and vine stretching by either dipping or spraying.

The synthetic fabric thus obtained has good high-speed card passing properties, passes through the filament process very smoothly, has minimal shedding of spinning scum, and is extremely insensitive to changes in temperature and humidity. .

In addition, small amounts of nonionic activators, anionic activators, cationic activators, amphoteric activators, etc. may be added to the oil composition of the present invention as long as the effects of the present invention are not lost. Brightener.

It is also possible to add dyes, oxidation inhibitors, etc.

Hereinafter, the explanation will be given by way of examples taking zero-start Ijl & Polyester II- as an example. However, the present invention is not limited in any way by the following examples. Furthermore, as an evaluation of spinnability, fruitfulness, spinning scarcity, The method for evaluating the coiling form and its dependence on temperature and humidity is as follows: 25℃, @! I%RH
