DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION The present invention relates to a textile product which, when used as a garment in direct contact with the skin, gives a moisturizing effect to the skin to maintain health and has excellent flexibility and texture, and has a washing resistance. It relates to a processing method.

[0002]

2. Description of the Related Art Conventionally, silicone oils, anionic, nonionic, and the like have been used as softening agents for imparting flexibility to fiber products such as spun yarns, knitted fabrics and nonwoven fabrics made of natural fibers and synthetic fibers. It has been proposed to treat with a cationic or amphoteric surfactant. JP-A-3-
No. 14674 discloses that a natural fiber material is treated with a cationic compound having a quaternary ammonium group and a reactive group which reacts with a hydroxyl group of the fiber, and then softened with an anionic softener.
Although a method of performing a step treatment is disclosed, the first step treatment has a disadvantage that it cannot be applied to any fiber material because it aims at a cationization reaction with a natural fiber material.

Further, in order to impart moisturizing properties to the skin as clothing, JP-A-2-300301 discloses that one kind of humectant or its microcapsules is adhered to clothing with a binder. Therefore, it is a garment made by a processing method inferior in flexibility and washing resistance. As a humectant, a product obtained by microencapsulating vitamin E and a squalane component and imparting it to fibers (trade name Rai Buri skin manufactured by Toho Rayon Co., Ltd.) is marketed, but its processing method is not disclosed. There is a concern that the garment may be yellowed because it tends to be deteriorated due to such factors. Under the circumstances described above, there has been a demand for the development of a method of processing a textile product having high washing resistance and exhibiting the durability of the effect while having a moisturizing effect, flexibility and tactile sensation.

[0004]

SUMMARY OF THE INVENTION The present invention solves the above-mentioned drawbacks, and provides a method of processing a textile product having a high washing resistance, which is superior in moisturizing effect, flexibility, and tactile sensation, and maintains these performances. I do.

[0005]

Means for Solving the Problems The present inventors have intensively studied for improvement in order to solve the above-mentioned problems and completed the present invention. The present invention provides a method for treating a fiber product with a cationic surfactant emulsified and dispersed aqueous solution, followed by drying, and then treating and drying with an anionic surfactant emulsified and dispersed aqueous solution in which a humectant squalane and jojoba oil are dispersed and mixed. It is a processing method.

The textile products used in the present invention include silk, cotton, hemp, wool, synthetic fibers made of polyamide, polyester, polyacrylonitrile, polyurethane, polyvinyl alcohol and the like and copolymers based on these, Spun yarn, knitted woven fabric, non-woven fabric and the like of single or mixed fibers made of any fiber material such as coarse rayon and acetate.

[0007] In particular, textile products used for lingerie, underwear, brassiere, body suits, underwear for Japanese clothing, pantyhose, girdle, belly band, socks, gloves, etc., which are worn in direct contact with the skin. Demonstrates an excellent effect on the processing of As a humectant, JP-A No. 2
Sorbitol, sodium hyaluronate, natural fats and oils such as jojoba oil and olive oil and coconut oil, polybutene, liquid polymer hydrocarbons such as hydrogenated polybutene, collagen, evening primrose oil, mink oil These derivatives and the like can be mentioned. However, according to the purpose of the present invention, as a humectant, it has high safety to humans, affinity for skin, high oxidative stability, has no effect on deterioration and yellowing of textiles, and has anionic surfactant emulsification. It is important to select one that has the ability to disperse and mix without disturbing the aqueous dispersion solution.

The inventors of the present invention have conducted intensive studies on a combination that achieves higher moisturizing performance with a combination of different moisturizing effects in addition to a synergistic effect by using one type of moisturizing agent. As disclosed specifically, it has been found that the combination of squalane and jojoba oil is excellent.

As the squalane, a partially hydrogenated and completely hydrogenated squalene derived from shark liver oil and olive oil or a synthetic squalane produced from isoprene as a starting material is used.

On the other hand, as jojoba oil, jojoba (Sim
and jojoba alcohol obtained by reducing the oil obtained by squeezing seeds of C. mondsia chinensis) with metallic sodium, refined oil of pressed oil, deodorized oil, hydrogenated oil, and jojoba wax. In any case, squalane and jojoba oil are compounds whose chemical structures are clearly different from each other as well as the organisms from which they are derived.

Squalane and jojoba oil are widely used as raw materials for cosmetics, and are not only excellent in oxidative stability but also
Affinity to the skin, also excellent in safety, well dispersed in anionic surfactant emulsified dispersion aqueous solution, as a moisturizing effect, squalane has the ability to prevent loss of water from the skin and retain an appropriate amount of water, It will give a feeling of sliminess to textile products processed using this, and jojoba oil has excellent permeability and absorbs high to the skin, leaving a refreshing feeling without giving an oily feeling Therefore, it gives a feeling of dryness to textiles processed using this. Therefore, it is possible to obtain the desired texture of the processed fiber product by providing the moisturizing property by mixing the two humectants and changing the mixing ratio of the two humectants. In addition, it can withstand aging (change in color tone of the product) as a fiber product.

The amount ratio of squalane and jojoba oil used together is as follows:
Squirt run-: 1 in a weight ratio of jojoba oil: 10 to 10: 1. Note that the present invention essentially requires the use of squalane and jojoba oil in combination, but other components known as fiber additives, such as squalene, can be appropriately added as long as the effects of the present invention are not impaired. .

The emulsified dispersion of the cationic surfactant used in the present invention may be any as long as it can be dispersed in water with the cationic surfactant conventionally used as a softening agent. Examples include, but are not limited to, polyamines, tertiary amines derived from fatty acids or fatty acid amides, quaternary pyridinium salts, quaternary ammonium salts, and the like.

The aqueous solution of emulsified and dispersed anionic surfactant used in the present invention can be dispersed in water with an anionic surfactant conventionally used as a softening agent, and well emulsifies squalane and jojoba oil. Any material can be used as long as it can be dispersed. Examples include, but are not limited to, sulfated higher alcohols, phosphorylated higher alcohols, sulfides of fatty acids or derivatives thereof, alkyl methyl taurate, sulfates of polyethylene glycol ether, and the like. Then, squalane as a humectant and jojoba oil are emulsified and dispersed to obtain an aqueous solution of anionic surfactant emulsified dispersion. Nonionic activators such as alkyl ether ethylene oxide, alkyl ether ethylene oxide propylene oxide, etc. It is preferable to emulsify and disperse in advance using the above and then emulsify and disperse in an anionic surfactant to form an aqueous solution.

[0015] method of processing textile product of the present invention, the textile is immersed in a cationic surface active agent emulsified dispersion solution mentioned above, squeezed with a desired drawing rate in such a mangle, 80 ° C. ~ depending on fiber products A drying treatment is performed at 160 ° C. for 60 minutes to 20 seconds. Next, the fiber product is immersed in an aqueous solution of an anionic surfactant emulsified dispersion in which squalane and jojoba oil are dispersed and mixed, and squeezed at a desired squeezing ratio with a mangle or the like at 80 ° C to 160 ° C for 60 minutes depending on the fiber product. It can also be processed by an exhaustion method using a drying method of 20 seconds or a cheese dyeing machine.

[0016] Particularly with respect to the amount of drug than water of cationic surfactant emulsified dispersion solution, squalane and the amount of drug weight ratio other than water of jojoba oil in anionic surfactant emulsification dispersion solution dispersed mixture Is preferably 1: 1 or more. The concentration of the cationic processing liquid, which is the aqueous solution of the emulsified and dispersed cationic surfactant, is usually 0.1 to 20 g / L,
The concentration of the anionic treatment liquid, which is an aqueous solution of the emulsified dispersion of the anionic surfactant to be treated, is relatively high because it contains squalane and jojoba oil, and is usually 0.1 to 200.
g / L. As described above, since the cationic and anionic surfactant emulsified and dispersed aqueous solutions are separately processed, the respective aqueous solutions can be recovered and reused, which is economically excellent.

According to the method of the present invention, squalane and jojoba oil are often uniformly mixed in an aqueous solution of an anionic surfactant emulsified and dispersed, and the processed fiber is used as a garment so as to come into contact with the skin surface, so that the moisturizing effect is obtained. Is exhibited.
Although the phenomenon of excellent washing resistance is not clear, fibers with anionic groups are not positively reacted with cationic surfactants, but do not easily react with cationic surfactants, but cause slight ionic bonding, making it difficult for fibers to peel off. It is presumed that anionic surfactants may have an ionic bond through a cationic surfactant for those having a functional group, and the layer composed of the cationic surfactant and the layer composed of the anionic surfactant are mutually separated. It is presumed that ionic bonds are strongly generated and integrated.

To obtain a fiber product by the method of the present invention,
After the treatment by the processing method of the present invention, it is difficult to dye the textile, so in order to obtain the textile product of the dyed and printed product, the textile product is pre-processed before performing the processing of the present invention. It is desirable to keep.

[0019]

[Example 1] Using a cotton spun yarn of 50th count single yarn, a warp of 285 yarns / 5 cm,
A cotton broad woven fabric having a density of 165 wefts / 5 cm and a basis weight of 100 g / m ² was woven and subjected to sintering, desizing, scouring, bleaching, mercerizing and drying by a conventional method to obtain a fiber product of a cotton broad woven fabric. (Unprocessed sample 1). The obtained cotton broad cloth is used as a polyamine-based cationic surfactant (Takamatsu Oil & Fat Co., Ltd.)
(Trade name, High Softener FC) in a 3.8 g / L-containing cationic surfactant emulsified and dispersed aqueous solution (hereinafter referred to as “cationic treatment liquid”) for 1.5 seconds, and squeezed at a squeezing ratio of 80%. A drying treatment was performed at 140 ° C. for 30 seconds. Next, squalane and jojoba oil are emulsified and dispersed in an alkyl ether ethylene oxide adduct and an alkyl ether ethylene oxide / propylene oxide adduct, which are nonionic surfactants, and an alkyl surfactant, alkyl methyl taurate, is mixed. After emulsification and dispersion, water is added to prepare an aqueous solution of an anionic surfactant emulsified dispersion.

At this time, the squalane, jojoba oil, alkyl ether ethylene oxide adduct, alkyl ether ethylene oxide / propylene oxide adduct, and alkylmethyltaurate were blended as shown in Table 1 to obtain 6.0 g / L, 12. 0 g / L, 18 g / L, 24 g /
L, 30 g / L, that is, the ratio to the concentration of the cationic surfactant is 1: 1.6, 1: 3.2, 1: 4.
An aqueous solution of an anionic surfactant emulsified dispersion containing squalane and jojoba oil (hereinafter referred to as an anionic treatment liquid) was prepared so that the ratio became 7,1: 6.3, 1: 7.9.

The cotton broad woven fabric obtained by processing with the cation-based treatment liquid is immersed in the anion-based treatment liquid having each of the above-mentioned concentrations for 1.5 seconds, and squeezed at a squeezing ratio of 80%. Drying treatment was performed at 140 ° C. for 30 seconds to obtain processed samples 2, 3, 4, 5, and 6 of the present invention. Table 1 shows the results of skin moisture content, flexibility, tactile sensation, and change over time for each of samples 1 to 6.

[0028]

[Table 1]

As is clear from Table 1, when the mixing ratio of squalane and jojoba oil is 1: 1 and the ratio of the concentration of the cation-based treatment solution to the concentration of the anion-based treatment solution is changed, the skin moisture increase rate increases as the concentration ratio increases. The increase, ie, the moisturizing effect, is improved, and the flexibility is also improved. The tactile sensation does not change, and the change with time (color tone change of the sample) has no effect at all.

Example 2 Using the cotton broad woven fabric (sample 1) obtained in the same manner as in Example 1, the concentration of 3.% was used in Example 1 . The immersion treatment was carried out for 1.5 seconds in a cation-based treatment liquid of 8 g / L, and the squeezing ratio was 80
After squeezing in%, a drying treatment was performed at 140 ° C. for 30 seconds.
Next, as shown in Table 2, the mixing ratio of squalane and jojoba oil was changed to 1: 4, 3: 7, 7: 3 and 4: 1, and a solution having a total concentration of 18 g / L in the anionic treatment solution was prepared and manufactured. Then, each sample was immersed in an anionic treatment solution for 1.5 seconds, squeezed at a squeezing ratio of 80%, and then dried at 140 ° C. for 30 seconds to obtain processed samples 7, 8, 9, and 10 of the present invention. Table 2 also shows the results of skin moisture content, flexibility, tactile sensation, and changes over time for each of 7 to 10 samples, and the results of Samples 1 and 4 of Example 1.

[0031]

[Table 2]

From the results in Table 2, it can be seen that even when the ratio of the concentration of the cation-based treatment liquid to the concentration of the anion-based treatment liquid is the same and the mixing ratio of squalane and jojoba oil is changed, the moisturizing effect is not affected, and the squalane ratio is reduced. increasing the decrease is Tsuyoshiyawara properties and texture, slimy feeling touch is deteriorated dry feeling increased. In contrast, the proportion of jojoba oil is improved in many cases the stiffness <br/> soft property beauty air if compared with squalane, slimy feeling tactile properties degraded, it is apparent that dry feeling is improved, Desired flexibility, feeling, etc. can be freely processed by changing the mixing ratio of squalane and jojoba oil. At this time, there is no effect on the change over time.

Comparative Example (1) Using the cotton broad woven fabric (sample 1) obtained in the same manner as in Example 1, the concentration of 3.8 g / L used in Example 1 was used.
Was immersed in the cation-based treatment liquid for 1.5 seconds, squeezed at a squeezing ratio of 80%, and then dried at 140 ° C. for 30 seconds. Next, it was immersed in an aqueous solution of an anionic surfactant emulsified and dispersed at a concentration shown in Table 3 in which only squalane was emulsified and dispersed as a humectant for 1.5 seconds, squeezed at a squeezing ratio of 80%, and dried at 140 ° C. for 30 seconds. Processed and processed sample 11
I got (2) An anionic surfactant having a compounding concentration shown in Table 3 in which only jojoba oil is dispersed instead of the above-mentioned humectant squalane
Using the emulsified dispersion aqueous solution, a processed sample 12 was obtained by the same operation as in the above (1). (3) The cotton broad fabric (Sample 1) was immersed in an anionic treatment solution having a 1: 1 concentration ratio of squalane and jojoba oil at a compounding concentration shown in Table 3 without processing with a cationic treatment solution. And processed samples 13 and 14 were obtained in the same manner as in Example 1. Skin moisture content, flexibility for each of 11 to 14 samples,
Results of tactile sensation and aging, and samples 1, 2 and
Table 3 shows the results of No. 4.

[0034]

[Table 3]

As is clear from Table 3, (1) that when squalane alone is blended without jojoba oil in the anionic treatment liquid, the rate of increase in water content is lower than when both humectants are mixed. obvious, although degraded even Tsuyoshi軟property and feeling slimy feeling has decreased dry feeling is improved. (2) moisture increase rate when the anionic treatment liquid jojoba oil alone formulation without a squalane into the slightly improved, but is improved slightly Tsuyoshi軟property and feeling dry feeling lowered sense of slime improved doing. (3) When processing was performed with an anionic processing solution without processing with a cationic processing solution, the rate of increase in water content was remarkably reduced from the results of Samples 2 and 13 and Samples 4 and 14, and the washing resistance was also reduced. I have. The flexibility is also reduced, and both the slimy and dry feelings are reduced. From this, it is apparent that the processing method of the present invention is superior in all respects as compared with the case where the squalane alone or the jojoba oil alone is treated with the anionic treatment liquid and the case where the treatment is not carried out with the cationic treatment liquid. .
