Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a saponin-containing fiber which is excellent in preventing rough skin and treating wounds, as well as in improving skin troubles such as asemo, cracks, red fins, and burns, and in treating tumors and hemorrhoids. It is a thing. More specifically, the present invention relates to a fiber to which a saponin-containing microcapsule is attached to give a durable saponin effect.

2. Description of the Related Art Conventionally, the juice obtained from vine and stem of loofah is called loofah water, which has been used as an antitussive expectorant and a diuretic. In addition, it is said that it acts as a moisturizing skin as a lotion, and furthermore, in Oriental medicine, trauma, burns, mange, tumor,
It has also been used to treat hemorrhoids and the like. It has been found from the recent research effects that the physiologically active substances that bring out the anti-inflammatory and skin-cleansing effects of loofah are saponin glycosides of luciosides and ginsenosides [Hayaki Hayashi, Fragrance Journal, 107, 37]. ~ 43 (1990)].
Further, JP-A-60-48995 also discloses a method for producing hemimasaponin.

[0003]

Conventionally, such loofah saponin has been used exclusively in liquid form, but since it is in liquid form, it is easily washed away and scattered during use, and loofah saponin is very expensive. Therefore, it has been a big problem to make it possible to use it efficiently so that it will not be washed away or scattered. On the other hand, on the other hand, there is a problem that a person with weak skin such as an infant or a woman may have rough skin or rash due to underwear, or an infant may get rash due to a diaper. The present invention has been made in view of such a current situation, and prevents the hemimasaponin from being washed away and scattered, enabling efficient use, and further, a fiber capable of preventing rough skin and skin irritation. It is intended to be provided.

Means for Solving the Problems As a result of intensive studies to achieve the above-mentioned object, the present inventors have found that hemimasaponin should be encapsulated in microcapsules and attached to fibers, and Reached

That is, the present invention is as follows: A fiber to which microcapsules containing hemimasaponin are adhered, wherein the adhered amount of the microcapsules is 0.00 as the adhered amount of hemimasaponin to the fiber weight.
Saponin-containing fiber of 1% by weight or more.

2. The saponin-containing fiber according to 1 above, wherein the microcapsules and the silicone resin binder are adhered at a ratio of 2: 1 to 1: 5.

The loofah saponin used in the present invention is an extract extracted from vine, stem and leaf of loofah, and its active ingredients are Lucioside A (1), B (2), C (3),
D (4), E (5), F (6), G (7), H (8),
I (9) and ginsenoside Re (10), Rg1 (11)
Are reported to be 11 types of saponin glycosides.

The method itself for producing such microcapsules containing hemimasaponin is known. The wall agent of the microcapsule is not particularly limited as long as it is broken by appropriate friction to release hemimasaponin or permeate and sustainedly release hemimasaponin at an appropriate rate, but organic polymers such as polyurethane, urea / formalin resin, etc. Is preferably used. The size of a microcapsule is usually 1
.About.50 .mu.m, preferably about 5 to 20 .mu.m, and the wall agent has a thickness of 0.3 to 3 .mu.m, preferably 0.5 to
It is about 1.5 μm.

The fibers to which the microcapsules containing hemimasaponin are attached may be natural fibers, regenerated fibers or synthetic fibers, and the fiber cross-sectional shape and the single yarn fineness are arbitrary,
Moreover, the form thereof is also arbitrary, such as long fibers, short fibers, webs, non-woven fabrics (synthetic papers), woven and knitted products, and sewn products according to the purpose of use.

The amount of hemimasaponin adhered to the fibers (total amount of hemimasaponin in the adhered microcapsules) needs to be 0.001% by weight or more, preferably 0.01% by weight or more. If the amount of loofah saponin adhered is less than 0.001% by weight, the anti-inflammatory effect, beautiful skin effect, rough skin, and rash preventing effect will be insufficient. The adherence amount of hemimasaponin increases as the amount increases, but if the amount is too much, hemimasaponin is expensive, resulting in extremely high cost.
Usually, it is preferably 2% by weight or less.

In the present invention, the microcapsules are preferably attached together with a binder. It is preferable that such a binder has excellent dispersibility in water and can be easily diluted with water. For example, a polyvinyl alcohol-based, silicon-based, or urethane-based resin binder is used. Above all, a silicone-based emulsion containing an organolinosiloxane as a main component and emulsified with an emulsifier is cured by removing water to form a rubber-like film, and therefore exhibits a durable adhesive effect.

The amount of the binder is preferably 0.5 to 5 times, particularly 1 to 2 times (weight ratio) the amount of the microcapsules. It is not preferable because the durability may be insufficient or the texture of the textile product may be hardened.

As the method of applying the treatment liquid containing the microcapsules and the binder to the fibers, any method such as a dipping method, a roller oiling method, or a spray method can be used, and it is applied at any stage of the fiber production. However, since it is not preferable to apply high temperature heat to the hemimasaponin, it is preferable to apply the treatment liquid after all the heat treatments on the fibers are completed.

For example, when producing short fibers made of synthetic fibers to which microcapsules are attached, stretching, crimping,
The treatment liquid containing the microcapsules was treated with a treatment liquid containing microcapsules to a toe just before cutting, which had been subjected to the heat treatment, so that the adherence amount of hemimasaponin was 0.0
It is applied by a roller oiling method so as to be 01% by weight or more.

When the fiber of the present invention is used for treating or improving skin inflammation, it can be used in the form of gauze, web, bandage and the like. Also, when synthetic fiber underwear, diapers, etc. cause rough skin and skin irritation, the use of the fiber of the present invention in which hemimasaponin is attached to the synthetic fiber can prevent skin roughening and rashes. .

EXAMPLES The present invention will be described in more detail below with reference to examples, but the present invention is not limited to these examples. In addition, parts and% in the following Examples and Comparative Examples
Indicates parts by weight and% by weight, unless otherwise specified.

[0017]

Example 1 and Comparative Example 1 An unstretched tow obtained by melt-spinning polyethylene terephthalate having an intrinsic viscosity of 0.64 measured with O-chlorophenol at 35 ° C. by a conventional method,
Stretched 4.5 times at 75 ° C, then crimped, 140
Relaxation heat treatment was performed at ℃. Microcapsules (average particle size 8 μm, film thickness 1 μm) containing a solution of hemimasaponin and water mixed in a ratio of 5:95 in the tow after the heat treatment 10
The treatment liquid mixed at a ratio of g / L and a silicone-based aqueous emulsion containing epoxy-modified dimethylpolysiloxane as a main component at 30 g / L was applied by a roller oiling device.

The tow to which the treatment liquid was attached was air-dried and then cut to obtain polyester short fibers having a fineness of 6 denier and a fiber length of 51 mm. The amount of loofah saponin attached to this polyester short fiber was 0.01% by weight.

On the other hand, in Comparative Example 1, a polyester fiber was obtained under the same conditions as in Example 1 except that the above treatment liquid was not used.

Each of the obtained short fibers was subjected to a skin roughening improving effect test on a human body panel. That is, a replica of a female face was taken, and rough skin was evaluated as shown in Table 1 based on the state of the skin pattern on the skin surface and the peeling state of the stratum corneum.
Twenty-five women with rough skin determined to be 2 were selected, and the webs of the above short fibers were attached to the face, and after 3 days, the state of skin improvement was observed and evaluated by the replica method in Table 1. The results are as shown in Table 2.
