JP2607953B2 - Sizing composition for fibers - Google Patents

Description

The present invention relates to a novel sizing agent containing squalane and / or squalene partially hydrogenated, which is used for sizing textile products (including clothing).

[Conventional technology and its problems] Textile products used for underwear, clothing, decorations, etc. are contaminated with sweat, lipids and other secretions secreted from the surface of human skin, dust in the air, and dirt. Is natural.

These soiled fiber processed products are washed, and a washing method is selected in consideration of the type of fiber used, its characteristics, the weave of the fiber, and the like.

That is, in general, there are dry cleaning and water-washing cleaning methods for textile products. In the dry cleaning, cleaning is performed using a solvent such as a halogenated hydrocarbon such as perchlorethylene, trichloroethylene, and trichlorotrifluoroethane, and a petroleum hydrocarbon, and a surfactant. This is suitable for a fiber-processed product in which fiber bleeding and texture may change due to washing with water.

On the other hand, in water-washing cleaning, a powdery, solid, or liquid detergent is dissolved and emulsified in water, and the detergent is used for washing. This method is used not only for business but also for general households. This is the easiest way to remove dirt and regenerate the fabric without danger.

After washing, it is then glued to prepare the mold to repair the mold breaks, smooth the wrinkles, or give a light texture. In the above-described dry cleaning, gluing is not usually performed because the shape is hardly lost.

This gluing, after washing with water with detergent, perform water rinsing,
The textile is immersed in an aqueous solution of the sizing agent or sprayed to dehydrate and dry. After drying, the mold is prepared by press working or the like to give a refreshing feeling. Pressing is performed by ironing or pressing with a press die.

However, the sizing agent used in the conventional water-washing may cause inflammation when worn in extreme cases, because the fabric after sizing becomes too hard. In addition, when gluing, the slipperiness of the iron may be deteriorated during pressing.
This causes a reduction in workability of ironing.

In addition, when gluing is performed, the fabric and the fabric come into close contact with each other after pressing, and the air permeability deteriorates. In addition, the mold release from the press mold at the time of the mold press becomes poor. This mold releasability also had various defects such as causing a reduction in workability of press working.

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

Means for Solving the Problems The present invention relates to a sizing agent composition for fibers comprising squalane and / or partially hydrogenated squalene, an aqueous sizing agent and a surfactant.

[Operation] 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 be used. These can also be used as a mixture. Considering that yellowing, off-flavor generation, etc. of the pasted fiber processed product occur due to poor oxidative stability of squalene, squalane which is more excellent in oxidative stability or squalene partial hydrogen having an iodine value of 3 or less is preferable. The use of additives is preferred.

The sizing agent is a water-soluble or water-dispersible natural or synthetic polymer which is a sizing agent conventionally used as an aqueous sizing agent. Specifically, starch derivatives such as starch, processed starch, CMC (carboxymethylcellulose), hydroxyethylcellulose or oxidative degradation products thereof, galactomannan, sodium alginate, polyvinyl alcohol, polyvinyl acetate, polyacrylate, polyacrylic acid Examples of the aqueous paste include a salt, a copolymer of maleic anhydride and ethylene and vinyl acetate, and a polymer base such as a synthetic polymer such as polyacrylamide.

The sizing agent is used in an amount of 10 to 200 parts by weight based on 1 part by weight of the partially hydrogenated squalane and / or squalene.

Since squalane is a hydrocarbon, it is difficult to disperse in an aqueous paste. Therefore, in the present invention, squalane or the like is dispersed in the paste by the action of the surfactant. As the surfactant to be used, any one of a nonionic surfactant, an anionic surfactant, a cationic surfactant, an amphoteric surfactant and the like can be used. Cationic surfactants and anionic surfactants cannot be used together, but others can be used in appropriate combinations.

Specifically, as nonionic surfactants, ethers such as polyoxyethylene octyl phenyl ether, polyoxyethylene glycene monostearate, polyoxyethylene sorbitan monooleate, polyoxyethylene sorbite tetraoleate, etc. Ether ester type, polyethylene glycol monooleate,
Lipophilic glycerin monooleate, sorbitan sesquioleate, ethers such as ethylene glycol monostearate, sucrose fatty acid esters, and nitrogen-containing systems such as alkylol amide and polyoxyethylene stearic acid amide; anionic surfactants As a carboxylic acid such as metal soap, a sulfate such as sodium lauryl sulfate, a phosphate such as polyoxyethylene alkyl phenyl ether phosphate and sodium polyoxyethylene oleyl ether phosphate; a cationic surfactant Quaternary ammonium salts such as distearyl dimethylbenzylammonium chloride; aromatics such as stearyl dimethylbezyl ammonium chloride; heterocyclics such as cetylpyridinium chloride; and zwitterionic surfactants , Betaine and lauryl dimethylamino acid betaine, aminocarboxylic acid type, such as β- laurylamino sodium propionate, imidazoline derivatives.

The surfactant is used in an amount of 0.05 to 1 part by weight of the partially hydrogenated squalane and / or squalene.
2.0 parts by weight, preferably 0.1 to 1.0 part by weight.

The sizing composition of the present invention can be used by adding conventionally known solvents, plasticizers, antioxidants, fungicides, and natural or synthetic fragrances in addition to the above three components.

Solvents, as plasticizers, ethyl alcohol, isopropyl alcohol, butyl alcohol, ethylene glycol, propylene glycol, 1,3-butylene glycol, diethylene glycol, dipropylene glycol,
Glycerin, sorbitol, polyethylene glycol,
Alcohols such as polypropylene glycol and higher alcohols; hydrocarbons such as liquid 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; beeswax, wax and carnauba Natural animal and plant waxes such as wax, lanolin and shellac; hydrocarbon waxes such as ceresin, microcrystalline wax and polyethylene wax; and silicone oil.

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

The squalane and / or squalene is appropriately added to water by the action of a surfactant and dispersed in the sizing agent to prepare the sizing agent composition of the present invention. In addition, squalane and / or squalene can be emulsified by the action of a surfactant to produce an emulsified product, and water can be appropriately added at the time of use and mixed with a sizing agent to produce a sizing composition.

When using the paste composition of the present invention, the paste composition is appropriately diluted with water and adjusted as an aqueous emulsion having a paste solid content concentration of 0.001 to 5% by weight. Therefore, the form before dilution may be in the form of an aqueous emulsion, cream, paste, gel or the like. In order to paste the fiber-processed product, the water-washed, dried or dehydrated fiber-processed product is treated by spraying or dipping an aqueous liquid adjusted to the above-mentioned solid content concentration. Thereafter, dehydration, drying, ironing, and pressing with a mold press or a wrinkle remover are performed.

For textile products, the sizing composition of the present invention is achieved by applying 0.001 to 5.0% by weight on a dry weight basis.
