TECHNICAL FIELD OF THE INVENTION
TECHNICAL FIELD The present invention relates to a fibrous structure having an excellent moisturizing effect and excellent in maintaining skin health.
[0002]
[Prior art]
In recent years, interest in health, hygiene, and the environment has been extremely increased, and in particular, attention has been paid to skin health, which is called skin care. This is due to an increase in the dry skin caused by atopy and the like and women who are interested in beauty, as well as men. For these reasons, there is a need for the development of clothing that is gentle on the skin and maintains the moisturizing effect on the skin surface.
[0003]
Examples of the fiber structure having a moisturizing effect include a skin care fiber product obtained by reacting a cellulosic fiber or the like with an amino acid or a natural polymer having an amino group after activating the hydroxyl group of cellulose (Patent Document 1). Or a garment in which a humectant such as squalane, squalene, or lanolin is adhered with a binder (see Patent Document 2). A fiber treating agent comprising a surfactant and a processing method have been proposed (see Patent Document 3).
[0004]
It is already known that amino acids, cosmetics, etc. are often used and have a beautiful skin effect.However, they penetrate the skin and enhance the metabolism from inside the skin, and help the skin to regenerate. Therefore, it takes time to realize the effect. In addition, those obtained by reacting natural polymers having amino groups with cellulosic fibers, cucumber, carrots, tomatoes, peaches, and those provided with plant-collected substances such as avocado and natural oil-soluble substances have a moisturizing effect on the fibers themselves. It is proposed to enhance When such fibers come into direct contact with the skin, the fibers take away the moisture of the skin, and on the contrary, the skin becomes dry, which is not preferable in terms of maintaining the health of the skin.
[0005]
Further, all humectants such as squalane are oil components, and the effect can be obtained only when the oil component adhering to the fiber is transferred to the skin. The humectant had to be gradually dropped from the fiber, and it was difficult to impart durability. Further, there is a problem that the oil component is oxidized and discolored with time, and there is also a problem that troubles such as yellowing easily occur during storage.
[0006]
A moisturizing beauty sheet has been proposed using pectin (see Patent Document 4). Hyaluronic acid, sodium chondroitin sulfate, collagen, pectin, silk powder, etc. are used as humectants, but the humectant is held between the fiber sheets and the surrounding edges are heat-bonded to form a bag. It is. When such a beauty sheet is soaked in water and affixed to a required site, a moisturizing effect can be obtained for the first time, and it is not suitable as clothing.

[Problems to be solved by the invention]
The present invention has been made in view of the background of the related art, and has as its object to provide a fiber structure having an excellent moisturizing effect and an effect of maintaining skin health.
[0012]
[Means for Solving the Problems]
The present invention has the following configuration in order to solve such a problem. That is, the fiber structure of the present invention is characterized in that pectin is attached to the fiber surface.
[0013]
BEST MODE FOR CARRYING OUT THE INVENTION
The present invention has been made on the above-mentioned problem, that is, a fiber structure having an excellent moisturizing effect and an excellent effect of maintaining skin health, and intensively studied, and pectin extracted from fruits such as citrus fruits and apples on the surface of the fiber. When they were attached directly to the skin and tried to directly contact the skin, they found that such a problem could be solved at once.
[0014]
The pectin referred to in the present invention is a natural high molecular polysaccharide extracted from fruits such as citrus fruits and apples, and particularly, apple pectin extracted from apples has a preferable effect. Such apple pectin has a function of lowering the blood concentration of histamine, which causes allergy, and can provide these antiallergic effects in addition to moisturizing components. Such pectins are roughly classified into two types, HM pectin and LM pectin, depending on the degree of esterification, and both are often used as gelling agents and thickeners in the food field. However, it has the property of easily forming a film.
[0015]
Conventionally, in order to fix such moisturizing components on fibers, it was necessary to cover and harden the resin with a role as a binder, but by using pectin as a moisturizing component as in the present invention, the pectin itself gelled. Due to the characteristics, the pectin can be fixed on the fiber using only pectin. Therefore, it is not necessary to use a resin that inhibits the moisturizing effect. Even when the resin is used, the amount can be significantly reduced.
[0016]
In the present invention, the pectin contains a cellulosic resin.
[0017]
The cellulose-based resin of the present invention includes, but is not limited to, hydroxyethyl cellulose, hydroxypropyl cellulose, carboxymethyl cellulose, methyl cellulose, and the like.

When such a cellulosic resin is contained in such pectin, the gelling effect of pectin is improved and the durability is greatly improved.
[0019]
The mixing ratio of the pectin and the cellulose resin is preferably 2: 1 to 10: 1. If the amount of the resin is not less than の of the pectin, a sufficient moisturizing effect cannot be obtained, and if the amount is less than 1/10, the pectin becomes difficult to form a film.
[0020]
In the present invention, the pectin contains at least one selected from saccharides, sugar alcohols and oligosaccharides. By further containing at least one selected from such saccharides, sugar alcohols and oligosaccharides, the gelling properties of pectin can be enhanced.
[0021]
As the saccharide of the present invention, sucrose, invert sugar, isomerized sugar, glucose, fructose, lactose, D-xylose and isomerized lactose can be used, and as the sugar alcohols, maltitol, sorbitol , Mannitol, erythritol, xylitol, lactitol, palatinit, saccharified reduced starch and the like can be used. As the oligosaccharide, kraft oligosaccharide, maltooligosaccharide, isomaltooligosaccharide, galacto-oligosaccharide, soybean oligosaccharide, dairy oligosaccharide and the like can be used.
[0022]
The processing liquid for attaching pectin containing at least one selected from saccharides, sugar alcohols and oligosaccharides to the fibers is preferably acidic to pH 4 or less. By making the acid side, the pectin is easily formed into a film.
[0023]
The present invention is a fibrous structure in which the pectin film, which is a natural moisturizing component, adheres to the fiber surface, and the pectin of the fibrous structure contacts the skin, thereby suppressing moisture that evaporates from the skin, It has the effect of preventing the skin from drying out and increasing the moisturizing effect.
[0024]
Such a coating may cover the fibers uniformly or partially.
