Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present invention relates to a novel sizing agent containing squalane and/or squalene partially hydrogenated for use in sizing textile products (including clothing).

[Conventional technology and its challenges] Textile processed products used for underwear, clothing, accessories, etc.
Secretions such as sweat and lipids secreted from the surface of human skin,
Naturally, it gets dirty with dust and grime in the air.

These soiled textile products are washed, and the washing method is selected in consideration of the type of fiber used, its characteristics, and the way the fiber is woven.

In other words, there are generally two methods for washing delicate products: dry cleaning and washing with water.

Dry cleaning is performed using surfactants and solvents such as halogenated hydrocarbons and petroleum hydrocarbons such as perchloroethylene, trichloroethylene, and trichlorotrifluoroethane. This is suitable for textile processed products where the texture and texture of the fibers may change when washed with water.

On the other hand, in water cleaning, a powdered, solid, or liquid detergent is dissolved and emulsified in water, and the detergent aqueous solution is used for washing. This method is used not only for business purposes but also for general households. This is the easiest and least dangerous way to remove stains and regenerate fabrics.

After washing, you can adjust the shape to correct deformation, smooth out wrinkles, or create a light texture.
It is then glued. In the dry cleaning mentioned above,
Normally, gluing is not done to prevent the shape from deforming.

This sizing is performed by washing with detergent, rinsing with water, immersing the fiber R product in an aqueous sizing solution or spraying it, and dehydrating and drying it. After drying, the mold is shaped using press processing to give it a smooth texture. Pressing is performed by ironing or pressing with a press mold.

However, the sizing agent used in conventional washing with water makes the fabric too hard after sizing, and in extreme cases may even cause irritation when worn. Also, gluing may worsen ironing slipperiness during pressing. This causes a decrease in the workability of ironing.

Also, if glued, the fabrics will stick together after pressing, resulting in poor ventilation. In addition, it becomes difficult to release the mold from the press mold during mold pressing. This mold releasability has various defects, such as being a cause of lowering the workability of press working.

In order to improve these drawbacks, it has been proposed to add silicone emulsions or polyethylene glycol, which is solid at room temperature, to the sizing agent, but satisfactory results have not always been obtained.

[Means for Solving the Problems] The present invention relates to a TA textile glue composition characterized by comprising squalane and/or a partially hydrogenated squalene, an aqueous glue, and a surfactant.

[Function] The squalane used in the present invention is produced by hydrogenating natural or synthetic squalene, such as squalene collected from the liver of fish such as sharks, according to a conventional method.

Alternatively, synthetic squalane can also be used. These can also be used as a mixture. Considering that the yellowing and off-flavor of pasted fiber products occur due to the poor oxidation stability of squalene, it is preferable to use squalene with better oxidation stability or squalene partial hydrogen with an iodine value of 3 or less. Preference is given to the use of additives.

The sizing agent is a water-soluble or water-dispersible natural or synthetic polymer that is a sizing agent conventionally used as an aqueous sizing agent. Specifically, starch, modified starch, CMC (carboxymethyl cello-X), hydroxyethyl cellulose aluminum or starch derivatives such as oxidized decomposition products thereof, galacto-mannan, sodium alginate, polyvinyl alcohol, polyvinyl acetate, polyvinyl acetate, etc. Examples include aqueous glues made of polymer base materials such as acrylates, polyacrylic acid salts, copolymers of maleic anhydride with ethylene and vinyl acetate, and synthetic polymers such as polyacrylamide.

The amount of the sizing agent is 10 to 200 parts by weight per 1 part by weight of squalane and/or partially hydrogenated squalene.

Since squalane is a hydrocarbon, it is difficult to disperse in water-based sizing agents. Therefore, in the present invention, squalane or the like is dispersed in the adhesive by the action of a surfactant. The surfactants used include nonionic surfactants, anionic surfactants,
Any of cationic surfactants and amphoteric surfactants can be used. Although cationic surfactants and anionic surfactants cannot be used together, other surfactants can be used in appropriate combinations.

Specifically, as nonionic surfactants, ethers such as polyoxyethylene octyl ether,
Ether esters such as polyoxyethylene glycene monostearate, polyoxyethylene sorbitan monooleate, polyoxyethylene sorbitate tetraoleate, lipophilic glyceryl monooleate, sorbitan sesquioleate, ethylene glycol monostearate,
Ethers such as sucrose fatty acid esters, nitrogen-containing surfactants such as alkylolamides and polyoxyethylene stearamide; Anionic surfactants such as carboxylic acids such as metal soaps, sulfate esters such as sodium lauryl sulfate, etc.
polyoxyethylene alkyl phenyl ether phosphate,
Phosphate esters such as polyoxyethylene oleyl ether sodium phosphate; As cationic surfactants, quaternary ammonium salts such as distearyldimethylbenzyl ammonium chloride, aromatic surfactants such as stearyldimethylbenzyl ammonium chloride; , heterocyclic surfactants such as cetylpyridinium chloride; examples of zwitterionic surfactants include betaine surfactants such as lauryl dimethylaminobutyric acid betaine, aminocarboxylic acid surfactants such as sodium β-lauryl aminopropionate, and imidacillin derivatives.

The amount of surfactant used is 0.05 parts by weight of squalane and/or squalene partially hydrogenated product.
~2.0 parts by weight, preferably 0.1 to 1.0 parts by weight.

In addition to the above-mentioned three components, conventionally known solvents, plasticizers, antioxidants, antifungal agents, and natural or synthetic fragrances can be added to the paste composition of the present invention.

Examples of solvents and plasticizers include alcohols such as ethyl alcohol, isopropyl alcohol, butyl alcohol, ethylene glycol, propylene glycol, 1,3-butylene gelcol, diethylene glycol, dipropylene glycol, glycerin, sorbitol polypropylene glycol, and higher alcohols; Hydrocarbons such as paraffin and liquid isoparaffin; Natural essential oils such as orange essential oil, jojoba oil, and refined mink oil; Higher fatty acids such as stearic acid; Natural animal and vegetable waxes such as beeswax, wood wax, carnauba wax, lanolin, and shellac; Ceresin Examples include hydrocarbon waxes such as , microcrystalline wax, and polyethylene wax; and silicone oil.

Next, a method of using the adhesive of the present invention will be described.

The sizing composition of the present invention is prepared by dispersing squalane and/or squalene in a sizing agent by appropriately adding water through the action of a surfactant. In addition, squalane and/or squalene can be emulsified by the action of a surfactant to produce an emulsion, and when used, water can be added as appropriate and mixed with a sizing agent to produce a sizing composition.

When using the paste composition of the present invention, it is diluted with water as appropriate to prepare an aqueous emulsion with a paste solid content concentration of 0.001 to 5% by weight. Therefore, the form before dilution may be an aqueous emulsion, cream, paste, gel, or the like. In order to glue a processed fiber product, the processed fiber product, which has been washed, dried, or dehydrated as described above, is treated by spraying or immersing it in an aqueous solution adjusted to the solid concentration as described above. Thereafter, pressing is performed by dehydrating, drying, ironing, and processing with a mold press or wrinkle smoothing machine.

For fiber processed products, this is achieved by applying the sizing composition of the present invention in an amount of 0.001 to 5.0% by weight on a dry weight basis.
