DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention has a durable antibacterial and deodorant effect and a moisturizing and protecting effect on the skin when used as a garment in direct contact with the skin. TECHNICAL FIELD The present invention relates to a method for processing a textile product having a property and texture and also having a washing resistance.

[0002]

2. Description of the Related Art Conventionally, as a softening agent for imparting flexibility to fiber products such as spun yarns, knitted fabrics and nonwoven fabrics made of natural fibers and synthetic fibers, silicone oils, anionic and nonionic, A method of treating with a cationic or amphoteric surfactant has been proposed.

Japanese Patent Application Laid-Open No. 3-14767 discloses a method in which a natural fiber material is treated with a cationic compound having a quaternary ammonium base and a reactive group which reacts with a hydroxyl group of the fiber, and then softened with an anionic softener. However, since the first-stage treatment aims at a cationization reaction with a natural fiber material, it has a disadvantage that it cannot be applied to any fiber material.

Further, in order to impart moisturizing properties to the skin as clothing, JP-A-2-300301 discloses that one type of humectant or its microcapsules is adhered to clothing with a binder. Therefore, it is inferior in flexibility and washing resistance. A product obtained by microencapsulating vitamin E and squalane as a humectant and imparting it to the fiber ( live name, manufactured by Toho Rayon Co., Ltd.)
Riskin ) has been put on the market, but its processing method is not disclosed. Vitamin E has a great tendency to deteriorate due to sunlight or the like, so there is a concern that the clothing may turn yellow.

On the other hand, in recent years, there has been proposed a number of antibacterial and deodorant fiber products due to the necessity of creating a healthy and comfortable living environment. For example, Bigua to impart antimicrobial
There has been proposed a method of applying a nitride compound and an organic silicon-based quaternary ammonium salt compound to a fiber material such as a fiber or a fabric. JP-B-63-54013, JP-A-63-175117 and JP-A-1-250413 disclose an antibacterial metal (Ag,
It has been proposed to impart antibacterial properties by ionic dissociation of (Cu, Zn).

[0006] However, the fibers and fabrics obtained by these methods are not necessarily safe for the human body because of the antibacterial agents used, and depending on the use,
There are many hygiene problems such as rash on the human body, especially for those with weak skin such as infants. For this reason, attempts have been made to fix chitosan or a derivative thereof, which has no toxicity to the human body and is extremely safe, to a fiber material and apply it to antibacterial and deodorant products.

However, in these methods, since chitosan is dissolved in an organic acid or an inorganic acid and used as a water-soluble chitosan salt, it is used in a mixture with a resin to maintain durability. For this reason, the texture of the fabric before the treatment is significantly impaired, and the fabric has drawbacks such as causing a change in hue. In addition, when a compound having an aldehyde group is used to bond the fibers constituting the fabric with the chitosan, it is not necessarily hygienic for humans, especially those with weak skin. was there.

[0008]

DISCLOSURE OF THE INVENTION The present invention has an antibacterial and deodorant property which is extremely safe and durable to the human body, and has an effect of moisturizing and protecting the skin when used as clothing which is in direct contact with the skin. The present invention also provides a method for processing textile products having high washing resistance, which maintains the health of the skin and maintains these properties in terms of excellent flexibility, texture and water absorption.

[0009]

Means for Solving the Problems The present inventors have made intensive studies to solve the above-mentioned problems, and as a result, have reached the present invention. That is, the present invention relates to a method of impregnating a fiber product with a chitosan acidic solution and then treating the fiber product with a basic solution to cause the fiber product to adhere by coagulating and regenerating chitosan, and to have at least two quaternary ammonium salts in the molecule. After crosslinking with nitrogen of the type and alkylbis- (2,3-epoxypropyldialkylammonium halide), which is a crosslinking agent having at least two reactive groups, and dipotassium glycyrrhizinate, which is a skin protective agent and a humectant, The present invention relates to a method for processing a fiber product, wherein coconut oil fatty acid-hydrolyzed collagen triethanolamine is treated with a nonionic surfactant emulsified dispersion solution which is dispersed and mixed. The fiber product used in the present invention may be a dyed product in advance, or may be dyed after coagulating and regenerating chitosan on the fiber product, and then subjected to cross-linking treatment, a dipotassium glycyrrhizinate as a skin protective agent. The coconut oil fatty acid-hydrolyzed collagen triethanolamine can be treated with a nonionic surfactant emulsified dispersion solution in which the mixture is dispersed and mixed.

The fiber product used in the present invention is made of silk, cotton, hemp, wool, synthetic fibers such as polyamide, polyester, polyacrylonitrile, polyurethane, polyvinyl alcohol, etc., and all fiber materials such as viscose rayon and acetate. It is a spun yarn of a single or mixed fiber, a knitted woven fabric, a nonwoven fabric, or the like.

[0011] In particular, the use of these textiles in direct contact with the skin, such as lingerie, underwear, brassiere, body suits, underwear for Japanese clothing, pantyhose, girdle, belly band, socks, gloves, etc. Demonstrates excellent effects for processing.

Chitosan is mainly deacetylated by subjecting chitin obtained by removing impurities such as calcium and protein from shells of crustaceans such as crabs and shrimps by an acid and alkali treatment, etc., by heating with caustic soda. Is a basic polysaccharide having an amino group having a molecular weight of several hundred thousand.

The molecular weight of the chitosan used in the present invention is not particularly limited, but is relatively low in molecular weight from the viewpoint of easy handling.
Those having 100,000 to 100,000 are preferable. The degree of deacetylation is determined in consideration of solubility in organic acids and inorganic acids and antibacterial and deodorant properties.
%, More preferably 80% or more. Chitosan is fixed to textiles by immersion and spraying using a chitosan acidic solution in which chitosan is dissolved in an organic acid such as formic acid, acetic acid, lactic acid, citric acid, adipic acid or tartaric acid, or an inorganic acid such as hydrochloric acid or nitric acid. Is attached to the product by the method or pad dry method. The immersion time and spraying time are not limited, and may be any time as long as the chitosan acidic solution sufficiently permeates into the product fiber. Then, after performing the drying process,
After the chitosan is sufficiently regenerated and neutralized by contact with a basic aqueous solution of ethylenediamine, ammonia, potassium hydroxide, sodium hydroxide or the like, it is washed with water until it becomes neutral and dried. In the present invention, after adhering the chitosan acidic solution to the textile, coagulating and regenerating the chitosan with the basic solution allows the crosslinking agent to react using the intramolecular amino group of the chitosan to impart durability. It is necessary for.

The temperature and time for drying can be appropriately set according to the type of fiber product and the processing speed. The amount of chitosan fixed to the fiber product is 0.01 to 1.0% by weight based on the weight of the fiber product in consideration of the antibacterial performance, flexibility, moisture retention, and the like of the fiber product after treatment according to the present invention.
Preferably from 0.03 to 0.7% by weight, more preferably from 0.05 to
0.5% by weight is preferred. The amount of chitosan adhered can be determined by adjusting the amount of pickup by squeezing using, for example, a roller. Below the lower limit of this range, it is not possible to impart antibacterial and deodorant properties to textile products,
It is difficult for the subsequent crosslinking reaction to proceed sufficiently, and as a result, adhesion of dipotassium glycyrrhizinate or coconut oil fatty acid hydrolyzed collagen, which is a skin protective agent, becomes insufficient, and a sufficient skin protective effect cannot be imparted. On the other hand, if the upper limit is exceeded, the fiber product becomes hard, and it is not possible to improve the flexibility such as texture even by finishing work to be performed later. still,
The fixation of chitosan can be performed before or after dyeing in the textile processing step. The coagulation and regeneration of chitosan can be performed in the same bath as the crosslinking treatment with a crosslinking agent.

Next, a cross-linking treatment is carried out to cross-link the chitosan with the fibers or chitosan, thereby forming a strong chitosan film on the fiber surface. As a crosslinking agent,
An alkylbis- (2,3-epoxypropyldialkylammonium halide) having at least two quaternary ammonium salt-type nitrogens in its molecule and at least two reactive groups, especially hexamethylenebis which is a chloride compound -(2,3-epoxypropyldimethylammonium chloride), hexamethylenebis- (2,3-
Epoxypropyldiethylammonium chloride),
Propylene bis- (2,3-epoxypropyldimethylammonium chloride), propylene bis- (2,3
-Epoxypropyldiethylammonium chloride)
Is preferred. These crosslinkers contain at least 2 in the molecule.
Quaternary ammonium salt type nitrogen and at least two reactive groups, and has antimicrobial performance by itself, so that the antimicrobial property is enhanced, and dipotassium glycyrrhizinate, which is a skin protective ingredient, etc. It is also preferable to keep The concentration of the crosslinking agent is preferably 0.5% by weight to 3.0% by weight. However, considering that an excessive amount may cause staining and the like, 0.8% to 2.0% by weight of dipotassium glycyrrhizinate and the like having desired antibacterial properties and a protective effect on skin are retained, and at the same time, chitosan is used. This is preferable for firmly fixing the fiber surface.

In the crosslinking treatment, it is preferable that the halide of alkyl bis- (3-chloro-2-hydroxypropyldialkylammonium halide), which is a precursor serving as the crosslinking agent, is chloride, and hexamethylene bis-
(3-chloro-2-hydroxypropyldimethylammonium chloride), hexamethylenebis- (3-chloro-2-hydroxypropyldiethylammonium chloride), propylene bis- (3-chloro-2-hydroxypropyldimethylammonium chloride), propylene Bis- (3-chloro-2-hydroxypropyl diethylammonium chloride) is preferred,
It is reacted with an aqueous solution of caustic soda having a concentration of 5% by weight to 2% by weight to form a cross-linking agent, and the basic aqueous solution is impregnated and impregnated with a fiber product having chitosan fixed thereto.
What is necessary is just to perform a steaming process at 0 degreeC. The steaming time is not particularly limited as long as the crosslinking reaction proceeds sufficiently, and can be appropriately set according to the basis weight of the fiber product and the like. Next, soaping is performed. Washing and drying in the soaping step are not particularly limited, and may be performed by a generally used method.

Examples of humectants include sorbitol, sodium hyaluronate, natural fats and oils such as jojoba oil, olive oil and coconut oil, liquid polymeric hydrocarbons such as polybutene and hydrogenated polybutene, collagen, evening primrose oil, mink oil and derivatives thereof. In addition, the humectant disclosed in JP-A-2-300301 can be used.

However, according to the object of the present invention, not only as a moisturizer but also as a skin protective agent, it has high safety to humans, affinity for skin and oxidative stability, and deteriorates and yellows to textiles. It is important to select a material that does not have the effect of the above and a material that has a performance of dispersing and mixing without any trouble in a nonionic surfactant emulsified dispersion solution containing a sucrose fatty acid ester as a main component. The present inventors have proposed a conventional 1
A combination that uses two types of moisturizers to achieve higher moisturizing and skin-protecting effects through the synergistic effect of two substances that have different skin-protecting and moisturizing effects, rather than simply obtaining a moisturizing effect from them. After careful examination of
As specifically disclosed in Examples described later, it was found that a combination of dipotassium glycyrrhizinate and coconut oil fatty acid hydrolyzed collagen triethanolamine was excellent. Dipotassium glycyrrhizinate and coconut oil fatty acid hydrolyzed collagen triethanolamine are widely used as raw materials for cosmetics and are not only excellent in oxidative stability but also excellent in affinity to skin and safety, and sucrose fatty acid esters The nonionic surfactant emulsified and dispersed in an aqueous solution mainly containing coconut oil fatty acid hydrolyzed collagen triethanolamine as a moisturizing effect,
Collagen is decomposed to a molecular weight of about 600, coconut oil fatty acid is added to this, and it is a surfactant of collagen dissolved in ethanolamine. Has the ability to prevent the loss of water and retain appropriate water. or,
Because it contains coconut oil fatty acids, it has excellent permeability and is highly absorbent to the skin, leaving a refreshing feeling without giving it an oily feeling. It gives a slimy feeling, and when absorbed into the skin, it can give a dry feeling in addition to the tendency to make the epidermis very smooth.

Dipotassium glycyrrhizinate is a component of the licorice extract and has an excellent anti-inflammatory and anti-allergic action as well as a moisturizing effect. Therefore, by mixing the two substances, the fiber product can be provided with a moisturizing property and also have a skin protection effect. In addition, it can withstand color change over time as a fiber product.

The combination of dipotassium glycyrrhizinate and coconut oil fatty acid-hydrolyzed collagen triethanolamine in the ranges of 0.03 to 0.07% by weight and 1.2 to 2.1% by weight, respectively, provides sufficient moisture retention. An effect, that is, a skin protection effect is obtained.

In the present invention, it is essential that dipotassium glycyrrhizinate and coconut oil fatty acid hydrolyzed collagen triethanolamine are used in combination. However, as long as the effects of the present invention are not impaired, components known as additives, for example, Squalane, squalene and the like can be added as appropriate.

The nonionic surfactant emulsifying and dispersing agent used in the present invention is a nonionic surfactant conventionally used as a fiber processing agent, which can be dispersed in water, and which contains dipotassium glycyrrhizinate and coconut oil fatty acid. Any substance can be used as long as it can emulsify and disperse the degraded collagen triethanolamine in good condition, but sucrose fatty acid used as an emulsifier for foods and pharmaceuticals is very safe because it has minimal irritation to eyes and skin. A nonionic surfactant emulsified dispersion containing an ester as a main component is preferred. The use concentration is not particularly limited, and may be used within a range that can provide desired flexibility.

According to the method of the present invention, after chitosan is uniformly coagulated and regenerated on the surface of a textile, at least two quaternary ammonium salt-type nitrogens and at least two reactive groups are present in the molecule. A fiber processed by using a nonionic surfactant emulsified aqueous dispersion in which dipotassium glycyrrhizinate and coconut oil fatty acid hydrolyzed collagen triethanolamine are uniformly mixed after being cross-linked with a cross-linking agent and fixed to the fiber surface. When the product is used as a garment in contact with the skin surface, it exerts an antibacterial and deodorant effect and a moisturizing effect, as well as a skin protective effect.
