2. Description of the Related Art Conventionally, as a method for imparting a texture to a fiber or a fiber product, a surfactant or a silicone softening agent having a texture property, or a mixture thereof is padded on the fiber or the fiber product and then dried and cured. A method is used, in which a solution containing a softening agent is heated, the fibers or textiles are repeatedly passed through the solution, the excess solution is removed by a mangle or a centrifuge, and then the solution is dried. ing. However, many of these have a softening agent merely attached to the surface of the fiber and are only temporarily provided with a texture, and only a non-durable material can be obtained. No measures or improvements were made to prevent deterioration of texture performance due to washing. Further, since the softening agent itself does not have a strong adhesive property to the fiber, there is a problem that the softening agent drops off from the fiber or the fiber product during the dehydration step using a centrifuge and causes soft spots.

Generally, when an anionic aqueous dispersion and a cationic aqueous dispersion are mixed, they are bound to each other by an ionic bond and agglomerate, and as a result, a stable dispersion mixture cannot be obtained. However, as a result of intensive studies conducted by the present inventors in view of the above, at least one of the anionic aqueous dispersion and the cationic aqueous dispersion contains a nonionic surfactant and / or a zwitterionic surfactant. Then, it was found that at a temperature of less than 35 ° C., the mixed dispersion was stable and the dispersion was not broken. If these are heated to 35 ° C or higher,
It was found that at the same time when the dispersion was destroyed, the softening agent was deposited as an ion complex with the softening agent contained therein, the ion complex was strongly adhered to the fiber surface, and the softening agent was simultaneously retained on the fiber. It was
As a result, it is possible to obtain a fiber or a textile product which has washing durability and has an excellent texture and a moisturizing effect, thus completing the present invention.

A nonionic surfactant and / or a zwitterionic surfactant is contained in at least one of the above, and an ion complex containing a softening agent is generated by heating to destroy the dispersion. A method for processing the described fiber or textile product. In a preferred embodiment, both the anionic aqueous dispersion (a) and the cationic aqueous dispersion (b) contain the same or different softening agents.

The invention according to claim 3 of the present invention is characterized in that the softening agent is at least one selected from squalane, squalene partially hydrogenated products and squalene, or the fiber according to claim 1 or 2. It is a method of processing textile products.

The fiber or textile product used in the present invention is
The material is, for example, a natural fiber such as silk, cotton, hemp or wool, a synthetic fiber such as nylon, polyester, polyacrytronitrile, polyurethane, polypropylene, rayon or bemberg, a semi-synthetic fiber or a mixed fiber. Can be mentioned. As the cloth foil made of the fiber, a knitted woven fabric or a non-woven fabric of the fiber alone,
Alternatively, it may be a mixed fiber cloth, such as a mixed spinning cloth, a mixed weave cloth, or a mixed knitted cloth cloth, and its structure and shape are not particularly limited. Preferred clothing includes pantyhose, tights, lingerie, petticoats, camisole, shorts and other underwear, girdles, brassieres, bodysuits and other foundations, and even clothing such as belly rolls and gloves that come into direct contact with the skin. Shows excellent effects.

As the softening agent used in the present invention, conventional softening agents for fibers or textiles can be used. For example, hyaluronic acid, sodium hyaluronate, pantotenyl ethyl ether, γ-oryzanol, allantoin, ethinyl estradiol, odrico grass extract, glycyrrhizic acid, placenta liquid,
Vitamin A, Vitamin E, sugar fatty acid ester, sodium caseinate, sodium chondroitin sulfate, glycerin, ethylene glycol, polyethylene glycol,
Polyvinylpyrrolidone, sodium pyrrolidonecarboxylate, sodium lactate, squalane, squalene, lanolin, gelatin, cholesterol, linoleic acid, L-ascorbic acid, sodium L-ascorbate, urea, migliol, alkyl myristate, perserine oil, α-amino acid (For example, cystine, aspartic acid, lysine, phenylalanine histidine, etc.),
Purple root extract, dipotassium glycyrrhizinate, jojoba oil,
Examples include rose water, evening primrose oil, mink oil and derivatives thereof.

Other softening agents of the present invention include natural waxes such as carnauba wax, beeswax, candelilla wax, spermaceti wax, sugar wax, mokuro, lanolin;
Synthetic waxes such as petrolatum, microcrystalline wax, petroleum wax, polyethylene wax; higher fatty acids such as capric acid, lauric acid, myristic acid, palmitic acid, stearic acid, behenic acid; lauryl alcohol, cetyl alcohol, n-stearyl alcohol, stearyl Higher alcohols such as alcohol, oleyl alcohol, behenyl alcohol, lanolin alcohol, hydrogenated lanolin alcohol, octidodecanol, and isostearyl alcohol; higher fatty acids and higher alcohols such as isopropyl myristate, isopropyl lanoline fatty acid, myristic myristate, and octyldodecyl myristate. Ester; higher fatty acid such as glycerin trimyristate and polyhydric alcohol ester; cetyl lactate, etc. Acid with higher alcohol esters, such as cyclic alcohol fatty acid esters, such as isostearic acid cholesteryl can be exemplified.

Other softening agents of the present invention include sorbitol, sodium hyaluronate, natural oils and fats such as olive oil and coconut oil, which are generally used as moisturizers, and liquid polymer hydrocarbons such as polybutene and hydrogenated polybutene. As long as it has no adverse effect on the skin and has a softening effect on fibers and textile products, it can be used. These softening agents may be used alone or as a mixture of two or more kinds. When the softening agent is ionic, it is necessary to select one that does not inhibit the formation of an ion complex when mixing the two types of emulsifier dispersion treatment liquids. In other words, an ionic softening agent can be used as long as it does not inhibit the formation of an ion complex.

Among these, nonionic or water-insoluble softening agents that particularly exert the effects of the present invention include natural products such as shark liver oil, squalene and squalene derived from olive oil, or isoprene. Synthetic squalane produced as a starting material, as well as jojoba oil and silicone oil. In particular, when a fiber or textile product is processed with an aqueous emulsion dispersion prepared by blending at least one of squalane and squalene as a softening agent in both of the two types of emulsions to be mixed, when they are worn, the coated skin is covered. It is preferable because the moisturizing performance of the surface can be improved.

Squalene is a substance which is biosynthesized in the human body and is recognized as a precursor of various steroid hormones. Further, squalene is found in various organs of the human body, and in particular, it is a main component in the sebum, and is secreted from the sebaceous glands like squalane, and is useful for the smoothness and prevention of dryness of the epidermis. However, squalene has 6 double bonds in the molecular structure, has poor oxidative stability, and is mainly used as a health food and as a base material for certain cosmetics. Squalane improves oxidative stability by completely hydrogenating the double bond of squalene.
It is an important substance that is widely used as a base material for cosmetics and pharmaceuticals because of its ability to penetrate the skin, its good affinity, and its physiological inactivity. As described above, the fact that both squalane and squalene have high safety to humans, high affinity for skin, high permeability, and high spreadability are major factors used as described above. Squalane is preferred for use in the present invention because it has higher oxidative stability, but squalene partially hydrogenated products and squalene can also be partially used as alternatives.

These softening agents may be used alone or in combination,
It is prepared in advance as an anionic aqueous dispersion or a cationic aqueous dispersion with an anionic surfactant or a cationic surfactant. Furthermore, the anionic aqueous dispersion and the cationic aqueous dispersion containing the commercially available softening agent may be used singly or as a mixture of two or more thereof, but the stability of the aqueous emulsion dispersion mixture of the present invention In order to maintain the sex, it is preferable to add a nonionic surfactant, a zwitterionic surfactant or both. The concentration of the softening agent is 0.1% by weight or more, preferably 0.5% by weight or more of the total amount of the anionic aqueous dispersion and the cationic aqueous dispersion. The upper limit can be used as an O / W aqueous dispersion up to a concentration at which a stable dispersion is maintained. If the concentration is less than 0.1% by weight, the amount of the softening agent adhered to the fibers or the fiber product is too small because it is too thin, and the softening effect cannot be improved. It may be processed several times, but it is not an economical processing method.

Anionic surfactants, cationic surfactants, nonionic surfactants and zwitterionic surfactants are available as surfactants for obtaining anionic aqueous dispersions and cationic dispersions in which a softening agent is dispersed. is there. Examples of the anionic surfactant include higher fatty acid soap, higher alcohol sulfate ester salt, N-amylglutamate salt, phosphate ester salt, sodium alkyl sulfate ester, sodium olefin sulfate ester, sodium alkylbenzenesulfonate, sodium alkylnaphthalenesulfonate, Alkylsulfate, sodium oleate amide sulfonate (trade name: Igepon T), sodium dialkyl sulfosuccinate (trade name: Aerosol

% By weight.

Examples of the cationic surfactant include alkylammonium salt, alkylpyridinium salt, alkylisoquinolium salt and benzethonium salt. The amount of the cationic surfactant used is appropriately determined, but is usually 5 to 200% by weight, preferably 10 to 50% by weight based on the total amount of the softening agent.

Examples of the nonionic surfactants include polyhydric alcohol ester type nonionic surfactants such as fatty acid monoglyceride, propylene glycol fatty acid ester, sorbitan fatty acid ester and sucrose fatty acid ester, and higher alcohol ethylene oxide condensates and fatty acid oxidation. Examples thereof include ethylene condensates, ethylene oxide condensates of sorbitan fatty acid esters, and block polymer type ethylene oxide condensed nonionic surfactants such as fatty acid alkylolamides.

Examples of the zwitterionic surfactant include alkyltrimethylaminoacetic acid (trade name: Batine), alkyldiethylenetriamineacetic acid (trade name: Tego) and the like. The amount of the zwitterionic surfactant used is appropriately determined, but it is usually 2 to 200% by weight, preferably 5 to 100% by weight based on the total amount of the softening agent.

To obtain the anionic aqueous dispersion and the cationic aqueous dispersion of the softening agent, the softening agent and the above nonionic surfactant and / or zwitterionic surfactant may be used alone or in combination of two or more. The combination and the anionic surfactant or the cationic surfactant can be prepared alone or in combination of two or more, but other than the above, the nonionic surfactant and / or the zwitterionic surfactant may be used as a softening agent. It is also possible to prepare a substantially anionic aqueous dispersion and a cationic aqueous dispersion by adding an anionic surfactant or a cationic surfactant after preparing the aqueous dispersion. In addition, a softening agent and a nonionic surfactant, which have been prepared in advance as described above, and / or
Or a nonionic surfactant and / or a zwitterionic surfactant-free softening agent anionic surfactant for a substantially anionic aqueous dispersion or cationic aqueous dispersion containing a zwitterionic surfactant The anionic aqueous dispersion prepared by the method described above or the cationic aqueous dispersion prepared by the cationic surfactant of the softening agent, or a combination of two or more kinds having the same ionic property, is used. It is also possible to prepare cationic and aqueous dispersions. After the anionic aqueous dispersion and the cationic aqueous dispersion have been prepared, they can be mixed to obtain the aqueous emulsified dispersion mixture of the present invention.

In any case, an anionic aqueous dispersion containing a softening agent and a cationic aqueous dispersion containing a softening agent, both of which are completely nonionic surfactants and / or zwitterionic surfactants When it does not contain, when these are mixed, an ion complex is easily formed at a temperature of less than 35 ° C. to cause precipitation. Thus, even in an aqueous dispersion of a softening agent having two kinds of opposite charges, if at least one of them contains a predetermined amount of a nonionic surfactant and / or a zwitterionic surfactant, Although they do not interact with each other even if they are in phase contact with each other at a temperature of room temperature or higher of less than 35 ° C, an ion complex is formed and dispersed by being heated to a specific temperature range of 35 ° C to 80 ° C. It has properties such that it breaks and precipitates by containing a softening agent. In the present invention, the presence of the nonionic surfactant and / or zwitterionic surfactant not only disperses the softening agent in water, but also causes the aqueous emulsified dispersion mixture of the present invention to form an ion complex at a temperature of less than 35 ° C. It helps to control.

In the present invention, a softening agent such as squalane, squalene, organopolysiloxane, and natural wax is used alone or as a mixture, and is mixed with an anionic surfactant, a cationic surfactant, a nonionic surfactant, a zwitterionic surfactant and the like. Prepared as an anionic aqueous dispersion and a cationic aqueous dispersion, respectively, and separately diluting and mixing with water in a storage tank or a bath. At this stage, the bath temperature is controlled to be less than 35 ° C. to prevent dispersion destruction. Then, the fiber or fiber product is dipped, heated to 35 ° C to 80 ° C, and mixed by stirring to form an ionic complex of anions and cations, which firmly adheres to the fiber surface and is softened at that time. By adhering the agent to the fiber, it is possible to obtain a fiber or a fiber product which has washing durability and has an excellent texture and a moisturizing effect. The mixing ratio of the anionic aqueous dispersion and the cationic aqueous dispersion is not particularly limited, but can be determined in consideration of economical processing temperature, time, etc., and is approximately 1/20 to 20 by weight.
/ 1, and preferably in the range of 1/2 to 2/1.

In the present invention, an antioxidant, an antistatic agent, an antibacterial agent, an ultraviolet absorber, etc. are added to the anionic aqueous dispersion, the cationic aqueous dispersion, or a mixture thereof, if necessary. It doesn't matter.

An anionic aqueous dispersion containing a softening agent and the like and a cationic aqueous dispersion containing a softening agent and the like, wherein at least one of them contains a nonionic surfactant and / or a zwitterion surfactant. The fibers or fiber products are immersed in a treatment liquid obtained by stirring and mixing contradictory ionic aqueous dispersions in a bath, and heated to a temperature at which dispersion destruction due to the formation of ion complexes occurs, and the ions are deposited on the fiber surface. By fixing the complex to the fiber, it is possible to make a fiber or a fiber product having a durable texture. The dipping operation can be performed continuously or batchwise. Immerse in a dipping bath under heating and stirring in the case of continuous type, or 35 ° C in the case of batch type
After dipping in a dipping bath of less than 50 ° C., it is gradually heated and kept at 35 to 80 ° C. for a predetermined time, or immersed in a bath heated and stirred at 35 to 80 ° C. for a predetermined time. In any case, it is necessary to immerse in an emulsified dispersion liquid in which an ion complex containing a softening agent is formed by heating, and thereby the emulsified dispersion is being destroyed.

As the anionic aqueous dispersion, an anionic surfactant alone or a combination of a nonionic surfactant and / or a zwitterionic surfactant and a softening agent are used alone or as a dispersion. Liquid mixtures and the like. It is necessary that at least one of the anionic aqueous dispersion and the cationic aqueous dispersion contains a nonionic surfactant and / or a zwitterionic surfactant. As the cationic aqueous dispersion, a cationic surfactant alone or a nonionic surfactant and / or
Or an aqueous dispersion of a softening agent in combination with a zwitterionic surfactant, alone or in a dispersion mixture. Next, the treatment method of the present invention with an ionic emulsion dispersion will be described in more detail. The anionic aqueous dispersion and the cationic aqueous dispersion are diluted and stirred with water in a bath, and the concentration of the softening agent in the bath (meaning the total of the softening agents in both solutions) is 0.1 wt% or more, up to a concentration at which stable dispersion is obtained, preferably 0.5 wt% or more to about 1
It is 0% by weight, more preferably 0.5% by weight or more to about 5% by weight. If it is 0.1% by weight or less, the amount of the softening agent attached will be too small and the effect will be insufficient. About 10% by weight
If it exceeds, the amount of the softening agent adhered is too large, the fiber or the textile product may be sticky, and may give discomfort, and the ion complex formation may be too early in some cases to make process control difficult, which is preferable. Absent.

The bath temperature for dipping the fiber or the textile product is 35 to 80 ° C, preferably 40 to 60 ° C.
If the temperature is lower than 35 ° C, the treatment liquid is stable and does not form an ion complex, which is not preferable. If the temperature exceeds 80 ° C, the time required for the formation of the ion complex may be shortened and water may evaporate depending on the concentration of the softening agent and the mixing ratio of the anionic aqueous dispersion / cationic aqueous dispersion. This is not preferable because it is difficult and it is difficult to uniformly attach the ion complex to the fiber or the fiber product. Further, the ion complex generation temperature can be arbitrarily set to some extent by selecting a combination of a cationic surfactant, a nonionic surfactant, a zwitterionic surfactant, etc., which is used in combination with the anionic surfactant.

Agitation of the treatment liquid in the bath is an essential condition. It is absolutely necessary for the ion complex to be uniformly deposited in the bath by stirring and to be fixed to the fiber product uniformly. The stirring method is not particularly limited, and pump stirring,
A known method such as a stirrer can be used alone or in combination.

The immersion time of the fiber or the fiber product in the treatment liquid is basically inversely proportional to the bath temperature, which is industrially,
It is economically selected, for example, between about 5 and 30 minutes,
Since it depends on various conditions such as temperature, a compounding ratio of anionic aqueous dispersion / cationic aqueous dispersion, and concentration of the softening agent, it is desirable to appropriately determine.

The features of the fiber or fiber product processing method of the present invention by the dipping method are that the surface and the inside of the fiber can be uniformly processed, no soft spots are generated, and the bathtub is easily managed. Is.

After the processing by the dipping method, the final processed product can be obtained by removing excess liquid with a mangle or a centrifuge and drying at 100 to 160 ° C. In addition,
After applying the processing method of the present invention to a fiber or a textile product,
