DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an oil agent for treating synthetic fibers. 2. Description of the Related Art In recent years, in synthetic fiber manufacturing and processing steps, speeding up has been remarkably accelerated for labor saving or rationalization. For example, the spinning speed of polyester or nylon is 40
It is shifting to 00-7000 m / min. On the processing side, the knitting speed in the knitting machine is increased to 1200 to 1500 times / min, and the weaving speed in the water jet loom is 1
The speed is increasing to 2,000 to 1200 rpm. When the speed is increased in this manner, the contact pressure of the running yarn with the yarn-attaching device increases, and the problem that the yarn-attaching device wears due to insufficient lubrication of the processing oil agent applied to the traveling yarn. It is getting close up. If the abrasion of the yarn-attaching equipment is left unattended, the quality of the yarn will be degraded. Therefore, the worn yarn-attaching equipment must be replaced, but this greatly reduces workability and productivity. With the recent increase in the speed of the synthetic fiber manufacturing process, oils for processing imparted to the synthetic fibers exhibit a high degree of lubricity and sufficiently exhibit abrasion resistance to the yarn-joining equipment. Is strongly required. The present invention addresses such a need,
The present invention relates to a new synthetic fiber treatment oil agent.

[0002]

2. Description of the Related Art Conventionally, various compounds have been proposed as oils for treating synthetic fibers, but none of these compounds satisfy lubricating properties and abrasion resistance which can meet the above-mentioned high demands in recent years. The fact is that there is no such thing. For example, a phosphoric acid ester salt represented by potassium lauryl phosphate is used in combination with a polyether, a sulfonate / sulfate, a high melting point ester, a modified silicone, a wax, a higher unsaturated fatty acid or the like (Japanese Patent Publication No. 62-3487).

0, JP-B-62-47991, JP-A-60-25274
8, Japanese Patent Application Laid-Open No. 56-118965), but the effect is not sufficient for increasing the speed in recent years. There is a disadvantage that scum tends to occur in the processing step. Alkenyl succinic acid soaps (JP-A-56-27070), dimer acid (JP-A-61-19811), organic amine salts of fatty acids (Japanese Patent Publication No. 62-34873), and the like must be used in large amounts. However, there is a drawback that the effect is not sufficient for speeding up.

[0003]

The problem to be solved by the present invention is that the conventional oil for treating synthetic fibers cannot exhibit the high degree of lubricity required in recent high-speed operation. This is inferior in abrasion resistance.

[0004]

Means for Solving the Problems Thus, the present inventors have
In view of the above-mentioned circumstances, as a result of intensive studies to obtain a synthetic fiber treatment oil agent that exhibits a high degree of lubrication and has sufficient abrasion resistance, each of an organic titanium compound having a specific structure and a lubricant component It has been found that a synthetic agent for treating synthetic fibers having a specific ratio is correct and suitable.

That is, according to the present invention, 0.1 to 10% by weight of an organotitanium compound represented by the following formula 1 and 99.9 to 90% by weight of a lubricant component comprising a lubricating oil and a surfactant.
And an oil agent for treating synthetic fibers.

[0006]

In the present invention, the organic titanium compound represented by the formula 1 is a linear condensed titanate. The organotitanium compound may include, as X in Formula 1, one or more of A, one or more of B, and one or more of A and one of B Alternatively, a material containing both of two or more is included, but a material containing both of them is preferable. And when both are included, A / B = 5 /
95-95 / 5 (molar ratio) is preferred, and 30/7
Those having a molar ratio of 0 to 90/10 are more preferable.

Examples of A include a methyl group, an ethyl group, an n-propyl group, an isopropyl group, an n-butyl group and an isobutyl group. Examples of B include: 1) alkyl such as n-hexyl group, n-heptyl group, n-octyl group, 2-ethylhexyl group, lauryl group, isotridecyl group, 2-octyldecyl group, stearyl group and 2-octyldodecyl group. group, 2) octadecenyl group, an alkenyl group such as Okutadodeseniru group, 3) a phenyl group, <br/> the aryl group such as a naphthyl group, 4) octylphenyl group, nonylphenyl group, alkylamine aryl group and dodecyl phenyl group, 5)

On the other hand, when n exceeds 50, the compatibility with the lubricant component becomes poor, and the manifestation of the desired effects of the present invention is reduced.

In the present invention, known lubricating oils and surfactants constituting the lubricant component used in combination with the organic titanium compound can be used. As lubricating oils, 1) mineral oils having various viscosities, 2) aliphatic monohydric alcohols and aliphatic monocarboxylic acids such as oleyl laurate, isooctyl stearate, butyl stearate, isotridecyl stearate, etc. 3) Esters of an aliphatic monohydric alcohol and an aliphatic dicarboxylic acid, such as 2-ethylhexyl azelate and dioleyl adipate;

Cationic surfactants such as alkyltrimethylammonium salts, alkyldimethylethylammonium salts, and alkylimidarinium salts; and 5) amphoteric surfactants such as alkyldimethylbetaines and betaines of alkylimidazolines.

The combination of the lubricating oil and the surfactant constituting the lubricant component and the mixing ratio thereof are not particularly limited. These can be appropriately determined depending on the type of the organotitanium compound to be used, the compounding ratio thereof, and other effects required as an oil agent for fiber treatment.

The synthetic fiber treating oil agent of the present invention comprises the above-described organic titanium compound and a lubricant component.
And organic titanium compound / lubricant component = 0.1 / 99.9
-10/90 (weight ratio), but 1/9
Those comprising 9 to 8/92 (weight ratio) are preferred. If the ratio of both is less than 0.1 / 99.9 (weight ratio), the effects intended by the present invention cannot be obtained. Conversely, both ratios are 1
If the ratio exceeds 0/90 (weight ratio), the organic titanium compound becomes difficult to dissolve in the lubricant component, and the manifestation of the desired effects of the present invention is reduced.

In using the oil agent for treating synthetic fibers of the present invention, in the spinning step, the drawing step, and each step after the drawing, the crude oil is used as it is, as an organic solvent solution, or as an aqueous emulsion, by roller oiling and a metering pump.
