Description

Description: TECHNICAL FIELD The present invention relates to a squalane composition used in the field of an oil agent for fiber treatment, particularly a softening agent. In particular, it has a low coefficient of friction and antistatic properties, and the emulsion is fine and has excellent stability over time. It does not cause oil burns or machine corrosion, can be stored for a long time, can be easily emulsified, and can be used in winter. The present invention relates to a fiber treatment oil agent, particularly a softening agent for fibers, which sufficiently satisfies the basic performance required for the fiber treatment oil agent, such as having a sufficiently low freezing point.

[Prior Art and Its Problems] Generally, in the spinning industry, any of natural cotton fiber, wool fiber or chemical fiber is prevented from charging, uneven texture or cutting of fiber due to increase in friction coefficient of fiber during spinning,
A fiber treating agent such as spinning oil or compounded oil is used to maintain a smooth spinning state. A typical oil agent is generally a mineral oil-based low-viscosity fluid paraffin and a combination of a surfactant and an antistatic agent as appropriate. In the case of such a mineral oil system, it cannot be said that a softening effect sufficient to sufficiently reduce the friction coefficient can be obtained, and when hydrogen purification is carried out to prevent oil burning and machine corrosion, the viscosity index lowers. Loss of fluidity at low temperatures. Although the emulsion is most commonly used in practice, it is not always sufficient in terms of long-term stability of emulsion and ease of emulsification.

Therefore, an object of the present invention is to provide an oil agent, especially a softening agent, which overcomes the drawbacks of the conventional fiber treatment oil agents.

[Means for Solving the Problems] That is, the present invention provides: (a) 100 parts by weight of a squalene hydrogenated product having an iodine value of 5 or less (b) polyoxyethylene sorbitan monooleate, polyoxyethylene sorbitan dioleate, polyoxyethylene At least one surfactant selected from the group consisting of sorbitan trioleate and sodium polyoxyethylene lauryl ether phosphate
The present invention relates to a fiber treatment oil composition comprising 15 to 100 parts by weight.

 The present invention will be described in more detail below.

The hydrogenated product of squalene is produced by hydrogenating squalene by a conventional method. Squalene can be used from any of fish liver oil such as shark and plants such as olive. Also, synthetic products can be used. The iodine value of the hydrogenated squalene of the present invention is 5 or less, preferably 1 or less. If the iodine value exceeds 5, the treated fiber is not preferable because it deteriorates with time and causes problems such as oil burning. Further, the hydrogenated product of squalene has a good fatliquoring effect, and particularly exhibits excellent permeability to animal fibers. Therefore, treating the fibers with the composition of the present invention softens the fibers.

The surfactant used in combination with the hydrogenated squalene is selected from the group consisting of polyoxyethylene sorbitan monooleate, polyoxyethylene sorbitan dioleate, polyoxyethylene sorbitan trioleate, and polyoxyethylene lauryl ether phosphate sodium salt. Is at least one surfactant. These surfactants can be used alone or in combination. The surfactant is used for forming a stable emulsion of the hydrogenated squalene and has no particular fiber softening effect by itself. Further, these surfactants have low irritation and high safety.

These are used in an amount of 15 to 100 parts by weight, preferably 25 to 50 parts by weight, based on 100 parts by weight of the hydrogenated squalene. If a surfactant is used outside this range, no stable emulsion composition can be obtained. Particularly preferably, polyoxyethylene sorbitan monooleate (the content thereof is A) and polyoxyethylene sorbitan trioleate (the content thereof is B) are used together, and the weight ratio A / B of both is 1 or less. It is appropriate to have.

In the present invention, in order to further increase the emulsion stability of the aqueous emulsion, a saturated organic mono- or dicarboxylic acid having a C ₈ or less is added in an amount of 0.5 to 5, preferably 0.7 to 1.0, based on 100 parts by weight of the hydrogenated squalene. It is preferred to add parts by weight. When a carboxylic acid having a carbon number of C ₈ or more is used or when the amount used is out of the above range, the effect of adding the carboxylic acid that improves emulsion stability cannot be obtained.

C ₈ or less saturated organic mono- or dicarboxylic acids include acetic acid, propionic acid, butyric acid, valeric acid, caproic acid, enanthic acid, caprylic acid, oxalic acid, malonic acid, succinic acid, glutamic acid, adipic acid, pimelic acid, suberin Acids and the like. Particularly preferred is succinic acid from the viewpoint of emulsion stability and safety.

Further, within the scope of the object of the present invention, other conventionally known surfactants or additives such as an antioxidant and a silicone compound as an emulsification aid polishing agent can be mixed in an appropriate amount.

The composition of the present invention is usually used in the form of an emulsion. Although such an emulsion composition can be produced by a conventionally known method, for example, a surfactant is gradually added to a squalene hydrogenated product under stirring, and after the completion, an aqueous carboxylic acid solution is similarly gradually added. Finally, add water to make an emulsion.

When it is used as a fiber treatment agent in the form of an emulsion, it may be prepared as an emulsion having an appropriate solid content concentration, immersed in a bath ratio of 5 to 30, preferably 10 to 20 for 10 to 30 minutes, and then dehydrated and dried.

[Examples] Hereinafter, the present invention will be described with reference to Examples, but the present invention is not limited to these Examples.

Production Example Blending method: 200 g of a hydrogenated product of squalene (iodine value 0.2) was stirred. To this, 40 g of polyoxyethylene sorbitan monooleate was gradually added with stirring. Then 10 g of polyoxyethylene sorbitan trioleate was slowly added. Next, 10% succinic acid aqueous solution (prepared at 60 ° C.) was added to each of 5, 10, 15, and 20 g so that 0.25 to 1.0 part by weight was added to 100 g by weight of squalene to prepare liquids having various succinic acid concentrations. . Finally, water was added so that the amount of synthesis would be 1000 g to prepare an emulsion of squalene with a hydrogenated product concentration of 20%.

The above-prepared composition was then diluted with water so that the solid content was 1%, and the milk value state after standing for 24 hours was visually observed. The results are shown in Table 1.

For comparison, hydrogenated squalene (iodine value 0.
2) A product having a solid content of 5%, which consisted only of a surfactant and succinic acid, was also produced without adding 200 g.

 The softening test of the fiber was performed as follows.

The area of four types of commercially available silk, cotton, hemp and wool
It was cut so as to have a size of 10 cm × 4 cm, and this was immersed in an emulsion having each of the above concentrations at a bath ratio of 10 and a temperature of room temperature for 20 minutes.

After that, 5kg using a mang roller (manufactured by Tsujii Dyeing Machine)
Was dehydrated under pressure with a load of 1, and then dried at 100 ° C. for 3 minutes by a jet dryer (manufactured by Tsujii Dyeing Machine).

The dry test pieces were compared by five panelists with the original test pieces that did not use the softener, and the degree of softening was evaluated according to the following criteria.

1 point got worse 2 points slightly worse 3 points unchanged 4 points slightly better 5 points Table 2 shows the improved results.

[Effect of the Invention] The hydrogenated product of squalene of the present invention is a reduction product of squalene obtained from shark liver oil and has a fatliquoring effect on fibers, and particularly exhibits good permeability to animal fibers. To do. Further, preferably, by adding a carboxylic acid, the composition of the present invention can be easily emulsified and dispersed even in a low concentration squalene or squalane emulsion composition, and the incoming dispersion state can be maintained for a long time.
