Description

[Detailed Description of the Invention] <Industrial Field of Application> The present invention relates to polyester fibers mainly for clothing, which have excellent passability through all processes and can yield high-quality textiles.

In particular, it relates to a spinning oil agent for polyester fibers for textiles, and more specifically, for a wide range of brands, it is concerned with textile fibers suitable for spinnability, stretchability, warping, weavability, and water jet loom weaving. Related to spinning oil. It is something.

<Prior art> Spinning oils for textile fibers have been commonly used for a long time, but unlike the recent rapid changes in oils for temporary combustion and oils for no-sizing yarn, there are currently only a few spinning oils based on mineral oil. Relatively fixed formulation lubricants have been used.

However, recently, the brands of drawn yarn for textiles have become wider, such as high count yarn, differential shrinkage yarn, and high temperature heat-treated drawn yarn. Various processes such as interlace processing, high twisting process, high-speed warping, weaving, and water jet weaving have been carried out for the purpose of this process, and the performance required for textile oils is wide and high. It is of the same level. In order to meet these performance requirements, oils containing various compounds have been proposed as textile oils. However, the oils that have been proposed so far do not have at least one of all process properties, that is, spinnability, stretchability, anti-interlace friction properties, high twist resistance, sizing properties, warping properties, and weavability. First, it does not have all-process properties, and even if it is effective for certain brands, it has almost no effect on many other brands. It lacked versatility.

<Problems to be Solved by the Invention> The present inventors have arrived at the present invention as a result of their studies to obtain a spinning oil for textile fibers that is excellent in all processes and has versatility for different brands.

Means for Solving the Problems〉 That is, the present invention uses redwood mineral oil (a) having a viscosity of 80 to 150 seconds, and fatty acid ester oil (a) having a melting point of 10°C or less.
b) and a polyoxyethylene ether nonionic activator (-c), and a blended oil agent containing these three components as the main component, contains all of the following three components
For a spinning oil for textile fibers characterized by a viscosity of 7 to 20 centipoise) Alkyl phosphate alkanolamine base (e) Alkyl 7-osphate alkali metal salt (e)
It is a metal salt of carboxylic acid.

In the present invention, it is essential to have one or more of each of the above-mentioned components (a) to (f), and if even one of these components is missing, the purpose of the present invention cannot be achieved. Not done. All of the components constituting the oil agent of the present invention are known, but the present invention provides that when specific compounds are combined from among the many compounds known as oil agent components, the individual compounds are completely free. It has been discovered that unexpected and excellent effects can be obtained. In addition to these ingredients, (g) modified silicone, (special wax),
(2) It has also been found that adding at least one member selected from the group consisting of ethylene oxide and/or propylene oxide compounds further improves overall process efficiency and brand versatility.

First of all, if we summarize the performance required in the entire process from spinning to product production, we will focus on spinnability, stretchability, interlace friction resistance, high twist resistance, sizing properties, warpability for weaving, and weaving properties. A typical example is gender. Components (a) to (f) constituting the present invention are all essential in order to obtain passability through all processes, but in which process these components are particularly effective, as described above (see The components of ) to (su) will also be explained below.

■ Spinnability: There are no particular problems as long as the emulsion stability of the oil agent itself is good and the emulsion viscosity is appropriate.

If uniform adhesion is required, follow the steps (a) to (a) above.
Further improvement can be achieved by adding, for example, a dialkyl sulfosuccinate salt in addition to the 1/l component.

■ Stretchability: In order to obtain drawn yarn with good uniformity, nonionic activators have been generally used, but nonionic activators with relatively low molecular weights are preferred for the same purpose, especially when heated. It is particularly effective to incorporate a relatively stable ether type nonionic surfactant (c).

Of course, mineral oil (a) and fatty acid ester oil (b) are used to obtain suitability for friction and wear with guides, stretched plates, etc.
It is preferable to mix the following. In addition, the recent proliferation of different brands of differentiated materials and interlace processing have required special ingredient formulations. For example, when drawing a no-ikarant yarn or high heat treatment, the filament tends to wind around the drawing roller or free roller frequently. As a component that improves the separation between such 7 filaments and metals, alkyl 7 phosphate alkanolamine salts)
The blending of is extremely effective, there is little abrasion with metal, and this component is also extremely effective as a component for preventing metal wear and reed wear during post-processing and weaving.

In addition, the viscosity at the secondary transition temperature of 75°C, which is a guideline for fluid lubricity in subsequent processes including the stretching process, is 7 to 20°C.
Being within the centipoise range is also a key point in adjusting stretchability and running tension.

■ Friction against interlace: In order to prevent the generation of fluff due to friction with guides and nozzles during interlace processing, mineral oil (a) alone as a base oil has poor oil film retention properties.

Preferably, fatty acid ester (b) is included. In addition, polyoxyethylene and/or polyoxypropylene compounds (so-called polyether compound components) are extremely effective as oil film protecting components, but they deteriorate the pasting properties and low friction properties in the subsequent process. It is not preferable to use a large amount, and it is preferable that the amount is about 10 or less.

■ Strong twist resistance The same tendency as for interlacing is observed for double twist resistance, and oil film protection is particularly required against friction from the perpendicular direction, which is different from friction in the fiber axis direction. .

■ Sizing properties: Mineral oil has traditionally been considered optimal for sizing properties, that is, sizing properties, desizing properties, and weaving properties, and is still widely used today. However, in order to increase the oil film security, yarn twistability, or weaving speed mentioned above, by using the mineral oil (a) and the fatty acid ester (b) in combination, lower metal friction properties can be further achieved.

■ General weavability: In conventional shuttle looms and rapya looms, components are required to prevent reed wear and prevent the generation of fluff. Although the effect of alkanolamine salt (on alkanolamine salt) is remarkable, it is also preferable to add fatty acid alkali metal soap (on) as an additional component, which forms a protective film on the metal surface and guide surface and prevents abrasion with the yarn. . It is also effective in preventing wear in dry conditions during each process.

■ Waterjet weavability: When weaving with waterjet, the atmosphere is wet, so
As the pace oil, it is preferable to add an ester oil (b) that has a high residual rate on the fiber surface, and an alkali metal salt of alkyl phosphate (e) as a component that improves wet friction properties and reed wear.

In this way, the oil of the present invention was proposed as a multi-purpose spinning oil for textiles.Moreover, modified silicone (T) was proposed as an additive that protects the oil film on the fiber surface and can withstand running at high speeds and high temperatures. Also effective is the addition of a special wax (a), and even greater process passability can be obtained.

Next, each component constituting the oil agent of the present invention will be explained in detail.

In order to achieve the object of the present invention, it is preferable to blend the compound (2) in an amount of at least one weight value.

There is no particular upper limit for the amount of each compound, but from the viewpoint of no longer improving the effect or the balance with other compounds, the compound () should be 20% by weight or less, and the compound (e) should be 1% by weight or less.
It is preferable that the content of the compound (I) be 0 weight % or less, and the content of the compound (f) be 10 weight % or less.

The present invention requires the above-mentioned six types of components (a) to (f), but in order to achieve even more advanced objectives, the above-mentioned (g) to (s) must be present. Each component may be added. Next, (a) to (c) and (g) to (I)
Each component of I) will be explained.

(a) Mineral oil Among the mineral oils represented by liquid paraffin and spindle oil, those having a redwood viscosity of about 80 to 150 seconds are used. If it is less than 80 seconds, it tends to scatter or emit smoke during high-temperature hot stretching, and if it is more than 150 seconds, the frictional tension is not appropriate. The blending amount is preferably in the range of 10 to 40% by weight of the total oil component.

(Example) It is an esterified product of fatty acid ester oil alcohol and fatty acid having a melting point of 10° C. or lower, and the alcohol and fatty acid may be monovalent or polyvalent. 1
As an ester consisting of a monohydric alcohol and a monovalent fatty acid, the alkyl group is not only a lower alkyl group such as a propyl group, but also a relatively higher alkyl group with a side chain (iso) type, such as an inoctyl group. or instearyl group, etc., and specific fatty acids such as lauric acid, myristic acid, and oleic acid are suitable.

In addition, when focusing is important, it is preferable to use a fatty acid ester of a polyhydric alcohol. Preferred specific examples of fatty acid esters include instearyl octanate, intridecyl palmitate, trimethylolpropane trilaurate, and the like. As for the amount,
A range of 10 to 40% by weight of the total oil component is preferred.

(c) Polyoxyalkylene ether nonionic surfactant Nonionic surfactants obtained by adding an alkylene oxide to an alcohol having 12 to 18 carbon atoms are included.

Polyoxyethylene is generally used as the polyoxyalkylene, but types with a low degree of polymerization (n) of the polyoxyethylene moiety (n) of 2 to 58 degrees 17) and types with a relatively high degree of polymerization of about 10 to 20 are used. A combination is preferable. The former is.

The latter is effective in improving stretchability, and the latter compensates for the low viscosity of the former, and is also effective as a joint component for emulsion stabilization, and also improves cohesiveness.

Preferred specific examples include polyoxyethylene lauryl ether, polyoxyethylene oleyl ether, polyoxyethylene castor wax, polyoxyethylene cetyl ether, polyoxyethylene nonylphenyl ether, and coconut. Examples include ethylene oxide adducts of the original fluorol. The blending amount is preferably in the range of 10 to 40% by weight based on the total oil component.

(g) Modified silicone Modified silicone includes modified silicone made by reacting a polysiloxane main chain with higher alcohol, higher fatty acid, polyglycol, polyoxyethylene, polyether, etc. as a side chain, and is particularly water-soluble or water-soluble. When a dispersible modified silicon is used, the overall process performance is improved, especially the handling property during scouring after the post-processing process is improved. The amount added is preferably 1 to 10% by weight and t% of the total oil component from the viewpoint of the above-mentioned effects.

(There are two types of special waxes commonly available on the market: copolymer of polyethylene glycol and terephthalic acid,
Alternatively, an alkyl group, a carboxylic acid group, or
Alternatively, there are polybutylene compounds to which esters of carboxylic acid and polyalkylene oxide are added.

Any of these can be used in the present invention. In all cases, those having a molecular weight of approximately 1,000 to 10,000 are preferred. The amount added is preferably 1 to 10 parts by weight based on the total oil component from the viewpoint of the above-mentioned effects.

(S) Ethylene oxide and/or propylene oxide-based compounds Ethylene oxide and/or propylene oxide are added to compounds with 1 to 8 carbon atoms that have hydrogen atoms that are easily reactive, and have a molecular weight in the range of 500 to 3,500. Polyether compounds are preferred. Particularly preferred is a copolymerized polyether compound to which ethylene oxide and propylene oxide are added together. The amount of polyether compound (su) to be blended is 5 to 10 weight tons based on the total oil component.
% is preferred.

In addition to the above components (a) to (s), other components may be added as necessary. Typical examples include dialkyl sulfate 7-osuccinate salts, as described above. To explain this compound, its alkyl group is generally an octyl group, and its salt is usually sodium. The preferred amount is:
By adding it in an amount of 2 to 10% by weight based on the total oil component, the penetration of the oil between fibers becomes particularly good. In order to improve the antistatic ability, it is preferable to use this compound together with an alkyl or alkyl sulfonate (7-one) Na salt or the like. In this case, the amount of the alkylsul7one) Na salt to be blended is 4 to 1 isz based on the total oil component.

In addition, it is desirable that each component constituting the present invention is liquid at room temperature, but even if some components have a high melting point, they may not be compatible with other components in the entire blended oil agent. Of course, such a compound may be used as long as it has good properties and maintains a stable liquid state at room temperature.

In addition, as a basic performance of the oil agent, it is preferable that each constituent component is stable in the entire blended oil agent, that is, does not separate, precipitate, or even form floating substances.

In addition, it is necessary for the oil agent of the present invention to have a viscosity of the stock solution in the range of 7 to 20 centipoise at 75°C in order to obtain all processability, and by setting the viscosity in this range,
Friction suitability, which is particularly important in achieving overall process efficiency, can be obtained. In addition, the undiluted solution viscosity mentioned here refers to the above (a) to (f).
This is the viscosity of the stock solution after blending not only the ingredients but also all the ingredients that make up the oil agent.

As described above, by using the oil agent of the present invention, a polyester filament yarn having passability through all processes, which was previously unimaginable, can be obtained.

The present invention will be explained below with reference to Examples.

Examples As shown in Table 1, ten types of compounded oils were extensively evaluated for each brand and various process properties shown in Table 2.

2300 (starting residue nitrimethylolpropane, terminal methyl capped product) Although it does not contain the components (f) and (b) and contains amine ether, and is expected to have some heat resistance and abrasion resistance, it is a conventional mineral oil-based oil agent, and has a wide range of brands and interlacing. The result is that there is a lot of fluff in the fabric, making it almost unsuitable for speeding up the loom or for W, J, and L.

Comparative Example 2 does not contain the following components:
It is an oil agent containing equal amounts of mineral oil (a) and ester oil (b), and the combination of ester oil improves interlacing processability and weavability in W, J, and L, but high count Threads and special drawn yarn brands tend to have a lot of fuzz, and the reeds in membrane weaving machines also suffer from severe wear.

Comparative Example 3 is an oil based on the formulation of the oil in Comparative Example 2, with the addition of 7-mole, 7-ate amine (→), but each process has been improved somewhat, and although it is bad as a multi-purpose, multi-brand oil, it is It is at a usable level. However, the passability of the post-process is still at the current level, and there are some fluffs and thread breakages in special brands. Therefore, phosphate alkali metal salt (E) ), and other special ingredients were blended in Examples 1 to 4.

In Example 1, a mixed base oil of mineral oil (a) and ester oil (b) is blended with a 7-osphatamine salt), a 7-osphate potash salt (e), and a carboxylic acid soap (b), and has ether-type nonionic activity. The oil agent of the present invention contains a low-molecular-weight active agent that exhibits high creep properties even when the oil is used.

With these formulations, good results were obtained regardless of the brand and processability, and the generation of stretched fuzz was improved, and at the same time, the uniformity was improved, making it suitable for use as a sizing agent in the summer, winter, and rainy seasons. It has good compatibility with reeds of general looms in mid-winter, as well as reeds of W, J, and L looms.

Example 2 is based on the formulation of Example 1 and further includes PEG/
When a small amount of polyester composite wax (T) was added and the secondary oil was used, a further reduction in the drawing fluff of the special brand was observed compared to Example 1.

Examples 3 and 4 are oils containing modified combinations of the components of the present invention, particularly oils containing a polyether component. There are no major defects in the general weaving process, and during stretching, interlacing treatment is performed with 1 strong twist and W.

J, L, it was found that the weavability was particularly excellent.

Next, in Comparative Examples 4 to 6, the formulation ingredients were sequentially changed from the oil agent of Example 1 to the phosphate amine salt.
This is a blended oil agent from which the phosphate alkali metal salt (a) and carboxylic acid soap (b) components have been removed. As a result, in accordance with the above-mentioned order, defects such as slight fuzz and reed abrasion increased in special grade stretchability, water jet loom weavability, and general weavability.

Regarding spinnability, there were almost no problems throughout the Examples and Comparative Examples.
