Description

Clothing

The present invention relates to women's clothing that is worn in contact with the skin like underwear and has a crotch structure or a breast covering structure, and particularly relates to women's underwear such as shorts and bras.

In women's underwear with a crotch structure like shorts, the crotch touches the wearer's skin directly. Then, the cloth of the material excellent in the touch and moisture absorption like cotton, for example, is sewn on the skin side of the crotch as a cover cloth (back gusset) (for example, refer patent document 1).

In such women's underwear, the wearer's vulva directly touches the crotch cloth (rear gusset), which can easily cause various stains when worn, causing itching, eczema, odors, and discomfort. Prone.

For this reason, it is conceivable to attach the extract component of the cocoon to the application cloth using the antibacterial and deodorizing effects of the cocoon (see, for example, Patent Documents 2, 3, and 4). In women's underwear having a crotch structure like shorts, a satisfactory refreshing feeling cannot be obtained.

The present invention seeks to provide a female undergarment having an exhilarating feeling of wear.

The gist of the present invention is clothing that is worn in contact with the skin, has a crotch structure or a breast covering structure, and at least a part of the crotch part or the breast covering part includes hemp or wrinkles. It is composed of a knitted fabric having a cover factor of 10 to 30 or a woven fabric having a cover factor of 400 to 1400, using at least a portion of a thread made of Japanese paper, and at least a part of one side of the fabric is skin side It is to be exposed clothing.

The cover factor of the fabric may be 600-1400.

The fabric may be a multiple fabric.

According to the present invention, a female undergarment having an exhilarating wearing feeling is provided.

According to the present invention, there is provided a women's undergarment in which an exhilarating wearing feeling is not lost even by washing.

The aspect of the garment of the present invention will be described using shorts as an example. A garment (shorts) 2 of the present invention is a garment worn in contact with the skin, and has a crotch structure and a crotch part 4 as shown in FIG. FIG. 2 is a schematic cross-sectional view of the crotch portion 4, and the crotch portion 4 is constituted by a fabric 8 made of a knitted fabric or a woven fabric. The upper surface A in the drawing of the fabric 8 is the skin-side surface of the crotch portion, and comes into contact with the skin when worn. Reference numeral 10 denotes a portion corresponding to the opening edge of the mouth of the clothing (shorts) 2.

The clothing of the present invention may have a structure as shown in FIG. 2 in which one side of the fabric 8 constituting the crotch portion 4 is exposed on the inner side (skin side) and the outer side of the fabric 8 is also exposed to the outside. Although most preferable in terms of the air permeability described above, as shown in FIG. 3 due to reasons such as the appearance design of clothing, a front cloth made of a normal cloth on the outer side of the cloth 8 (on the side opposite to the skin side). 9 may be provided. Note that a part of the surface of the fabric 8 on the skin side, such as an edge, may be covered with another fabric for design reasons. It is preferable that the fabric 8 is exposed at least 70% or more of the inner surface of the crotch portion 4 so as to be in direct contact with the skin.

Although the embodiment of the present invention has been described above by taking shorts as an example, the present invention can be similarly applied to a crotch part or a breast covering part of female clothing having a crotch structure or a breast covering structure. When applied to the breast covering part, it is preferable that a cloth corresponding to the cloth 8 is attached to the back side of the main body of the breast covering part by sewing or the like so as to be in contact with the skin.

In the present invention, whether the fabric 8 is a knitted fabric or a woven fabric, a gap is formed between yarns adjacent to each other in the surface direction of the fabric in the structure. That is, the cover factor is smaller than that of a normal knitted fabric or woven fabric. The reason and effect will be described later.

The fabric 8 is woven or knitted using yarn made of Japanese paper containing hemp or straw. As a result, the fabric 8 contains hemp, cocoon, or cocoon extract components. Hemp and cocoon are known to have antibacterial and deodorant performances (see, for example,

Patent Documents

2, 3, 4 and JP-A-11-241253), and the fabric 8 contains this component. As a result, it has antibacterial and deodorizing effects. However, when a cloth having a dense structure and poor air permeability, such as cotton (cloth) used as a backing cloth (back gusset) for conventional shorts or the like, is used as a base material for the cloth 8, it is also an itch in the wearing test. In addition, discomfort caused by eczema and odor is not resolved, and refreshing feeling as expected due to deodorizing and antibacterial effects cannot be obtained. In addition, the refreshing feeling that would be expected when using Japanese paper with hemp or cocoon as the lining cloth (back gusset) in place of cotton as a substitute for the cloth cannot be obtained.

In the present invention, hemp means ramie, flax (linen), Manila hemp, sisal hemp, red hemp (Rafu hemp), and jute.

In the present invention, buds indicate the leaves of plants belonging to the family Gramineae. Among the plants belonging to the family Gramineae, there are the genus Mushroom, Narihirada, Tochiku, Okamesa, Sasa, Azumasa, Yadatake, Medaka, Kanchiku, Horaichiku, etc. , Kinmei mochichiku, kikkouchiku, kinmeichiku, blackfish, hotechiku, mushrooms, narihiradake, suzunarihira, tochiku, prickly pears, tuna sasa sasa, sasa sasa sasa included.

The inventor of the present application is deodorized because the reason for this is that the air permeability of the base material is poor, so that fresh air is not continuously exposed to hemp or cocoon, or cocoon extract components when worn. The inventor arrived at the present invention by conceiving that the antibacterial effect was not sufficiently exhibited.

In the present invention, as described above, the fabric 8 is formed of a knitted fabric or a woven fabric, and the interval between the constituent yarns adjacent to each other in the knitted or woven fabric is approximately 0. It is about 2 to 1.5 times. As a result, fresh air is continuously exposed to the hemp or cocoon or cocoon extract component contained in the constituent yarn when worn, and the deodorant and antibacterial effect of the hemp or cocoon or cocoon extract component Is fully exerted, and a satisfactory refreshing feeling can be obtained. Further, one side of the fabric 8 is a skin side surface of the crotch part or breast covering part. Also by this, the fresh air is continuously exposed to the portion of the fabric 8 that is most prone to be in contact with the skin when being worn, and the deodorizing and antibacterial effects are sufficiently exhibited. This effect is better in the case of cocoon than in the case of hemp.

The state of such a gap in the knitted fabric or woven fabric constituting the fabric 8 can be indicated by a cover factor. The cover factor of the knitted fabric or woven fabric constituting the fabric 8 is smaller than that of a normal knitted fabric or woven fabric, and is in the range of 10 to 30 for the knitted fabric, and in the range of 400 to 1400 for the woven fabric. As a result, the air permeability of the fabric 8 is ensured as described above, and the unevenness due to the yarn on the contact surface with the skin of the fabric 8 is maintained and the adhesion with the skin is reduced. The fresh air is continuously supplied to the air, and the deodorant and antibacterial effects peculiar to hemp or straw are fully exhibited.

The cover factor of the knitted fabric represents the coverage of the knitted fabric, and is obtained by the following calculation formula according to the stitch length and the cover factor method of JIS L1018. However, in the present invention, when the fabric 8 has a multi-layered structure or a multi-knitted structure having a multilayer structure, the cover factor is defined as being applied to the structure of the layer on the most skin side.
K = √NT ÷ SI
here,
K: Cover factor NT: Fineness (dtex)
Sl: stitch length (cm).

The cover factor of the fabric is calculated by the following formula.
CF = (DWp / 1.1) ^1/2 × MWp + (DWf / 1.1) ^1/2 × MWf
here,
DWp: Total warp fineness (dtex)
MWp: Warp weave density (main / 2.54cm)
DWf: Weft total fineness (dtex)
MWf: Weft weave density (main / 2.54 cm).

When the cover factor increases beyond this range, the air permeability of the fabric 8 is impaired due to the high density of the knitted fabric or the woven fabric, and the unevenness due to the yarn on the contact surface with the skin of the fabric 8 is reduced. Since the adhesiveness with the skin is improved, the continuous supply of fresh air to the constituent yarns of the fabric 8 is hindered, and hemp or peculiar deodorant and sufficient antibacterial effects cannot be obtained.

Further, when the fabric 8 is a woven fabric and the cover factor is 1250 or less, in the above-described women's clothing using the fabric 8, the continuous supply of fresh air to the constituent yarns of the fabric 8 is extremely smooth when worn. It is more preferable because an exhilarating feeling is obtained.

In the present invention, when the fabric 8 has a multi-layered structure or a multi-knitted structure with a multilayer structure, the above-described range of the cover factor is applied to the structure of the layer on the most skin side. It is more preferable that each layer satisfies the above-described range of the cover factor.

If the cover factor is smaller than this range, the form maintaining property of the fabric 8 is impaired, and it becomes difficult to maintain the form as a crotch part or a breast covering part.

Further, when the fabric 8 is a woven fabric and the cover factor is less than 600, in the above-described women's garment using the fabric 8, the fabric 8 is misaligned by wearing for a long period of time as a crotch portion or a breast covering portion. This form may be difficult to maintain. Therefore, when the fabric 8 is a woven fabric, the cover factor of the fabric 8 is more preferably 600 to 1400.

In the present invention, as described above, a cloth using at least part of a thread made of Japanese paper containing hemp or cocoon is used, but a knitted fabric is manufactured in advance using a thread using a normal fiber material for clothing. After that, when the fabric 8 constituting the crotch part or the breast covering part is obtained by applying the cocoon extraction component to the knitted fabric, the antibacterial and deodorizing functions are lost due to the extraction component falling off by washing. Is called. It was found that the antibacterial and deodorant functions can be maintained even by repeated washing when using a cloth made of at least part of a thread made of Japanese paper containing hemp or straw.

That is, in the present invention, a knitted fabric is made using yarn made of Japanese paper containing hemp or cocoon, and this knitted fabric is used as the fabric 8. The apparel of the present invention in which the fabric 8 made of such a knitted fabric is used for the crotch portion and the breast covering portion has almost no falling off due to washing of hemp or heel components. The effect can be maintained even after repeated washing.

Furthermore, it is not only difficult to produce normal spun yarns and filament yarns with a fineness of the order of 0.1 dtex, but even if they are obtained, the yarns are dull and bulky. In particular, it is difficult to produce spun yarns and filament yarns made of ultrafine fibers made of natural cellulose fibers having excellent hygroscopicity. On the other hand, Japanese paper containing hemp or straw is fibrillated to a fineness of the order of 0.1 dtex, and is composed of ultrafine pulp-like fibers made of natural cellulose fibers with excellent hygroscopicity arranged almost randomly. Therefore, when a knitted fabric is made using this Japanese paper yarn and this knitted fabric is used as the fabric 8, it is bulky and feels better than a knitted fabric using ordinary spun yarn or filament yarn. Even if it is in direct contact with delicate skin areas such as the vulva and breast, there is little irritation and it is difficult to cause rashes. Also, in normal spun yarn and filament yarn, the fibers are entangled only by twisting, so fluff and pills are likely to appear in thin fibers, but this Japanese paper has fibrillated ultrafine fibers bonded together by hydrogen bonds. Therefore, it is difficult for fluff and pills to come out during use. Furthermore, in the apparel of the present invention in which the fabric 8 made of a knitted fabric using a yarn made of such Japanese paper is used for the crotch portion or the breast covering portion, the pulp-like cellulose fibers in the yarn are entangled with hemp or wrinkles. Holds hemp or cocoon, and there is almost no shedding of the hemp or cocoon ingredients by washing. The effect can be maintained even after repeated washing.

Japanese paper containing hemp or cocoon used in the present invention (hereinafter also referred to as hemp paper or cocoon paper) is beaten in the same manner as in the production of ordinary Japanese paper by mixing hemp or cocoon with the pulp of the Japanese paper after beating. Manufactured. Alternatively, it is manufactured by mixing the beaten hemp with the beaten beak. Further, it may be produced by only beating the beaten hemp. The mixing ratio of beaten cocoons in Japanese paper is preferably 1 to 10% by weight. The mixing ratio of beveled hemp in hemp Japanese paper is preferably 5 to 100% by weight.

It is preferable that the basis weight of hemp Japanese paper or Japanese paper is 10 to 20 g / m ² . Hemp Japanese paper or Japanese paper is slit by a slitter to form slit yarn. The width of the slit yarn is preferably 1 to 5 mm. The slit yarn is preferably twisted to form a yarn for a knitted fabric, and the yarn is knitted or woven to obtain a knitted fabric for the fabric 8.

The slit yarn is preferably twisted alone and used as a yarn for knitting, but may be used by twisting with other yarns. The knitted fabric for the fabric 8 may be one obtained by knitting or weaving a yarn using hemp washi or kashiwa paper and another yarn, but knitting using only hemp washi or shiwa paper. More preferably. In the case of knitting or knitting, it is preferable that at least 50% by weight or more of the knitted fabric for the fabric 8 is composed of slit yarns.

The knitted fabric used in the present invention is more preferably a woven fabric in terms of form stability because of its low density. Among them, it is a multi-woven fabric that contains a lot of hemp or wrinkles despite its low density, has good shape stability, and can increase the surface area exposed to the outside air of the constituent yarn, Further preferred. A double or triple weave is preferred.

The present invention is applied to a female garment that is worn in contact with the skin like underwear as well as shorts and has a crotch structure or a breast covering structure, and the crotch part or the breast covering part directly touches the wearer's skin. It can be suitably applied. Such women's apparel includes underwear called crotch parts, underwear called innerwear or underwear, and various types such as panty girdles in addition to shorts. is there. Examples of those having a breast covering part include a brassiere, a body suit, a lingerie, and an inner wear.

Kumazasa leaves were cut into 0.5 to 5 mm pieces, mixed with water and beaten with a home mixer, and then centrifuged to obtain pulp-like Kumazasa. This pulp-like kumazasa was mixed with Japanese paper pulp, and paper was made to obtain koji paper with a basis weight of 15 g / m ² . The content of Kumazasa leaves in Japanese paper was 1% by weight. The kneaded paper was slit to a width of about 2 mm and twisted at a twist number of 200 T / m to obtain a 1/32 count (312.5 dtex) yarn. An oblique (1/3) double woven fabric composed of upper and lower layers was woven using this yarn. The connecting parts are arranged in a staggered pattern every 26 vertical. The density of each layer was a warp density of 13.8 / cm and a weft density of 13.0 / cm. The cover factor for each layer is 1147.

The obtained woven fabric was finished in accordance with a normal finishing process and used as a fabric 8 in the form shown in FIG. The part except a crotch part used the said part of commercially available shorts (cotton knitting use).

Flax (linen) fibers were beaten in accordance with a normal Japanese paper manufacturing process to obtain a pulp-like slurry. This slurry was made into a hemp washi paper having a basis weight of 15 g / m ² . A woven fabric obtained from this hemp paper in the same manner as in Example 1 was finished in accordance with a normal finishing process and used as a fabric 8 in the form shown in FIG. The part except a crotch part used the said part of commercially available shorts (cotton knitting use).

Kumazasa leaves were cut into 0.5 to 5 mm pieces, mixed with water and beaten with a home mixer, and then centrifuged to obtain pulp-like Kumazasa. This pulp-like kumazasa was mixed with the hemp slurry obtained in Example 2 and paper-made to obtain koji paper with a basis weight of 15 g / m ² . The content of Kumazasa leaves in Japanese paper was 1% by weight. A woven fabric obtained in the same manner as in Example 1 from this koji paper was finished according to a normal finishing process, and used as a fabric 8 in the form shown in FIG. The part except a crotch part used the said part of commercially available shorts (cotton knitting use).

The fabric obtained in Example 3 was finished according to a normal finishing process, used as a cloth for the innermost layer of the brassiere, and used for one week. During that time, I did laundry once a day. During the wearing period, the feeling of wearing was soft, and the feeling of wearing was extremely refreshing without any itching or smell.

Shorts were prepared in the same manner as in Example 1 except that the warp density was 15.5 pieces / cm, the weft density was 14.5 pieces / cm, and the cover factor of each layer was 1280. The feeling of wearing was exhilarating, but the one of Example 1 was more exhilarating.

Shorts were prepared in the same manner as in Example 1 except that the warp density was 6.9 pieces / cm, the weft density was 6.0 pieces / cm, and the cover factor of each layer was 550. Although the feeling of wearing was refreshing, the cloth 8 was misaligned by wearing for one week, and the shape of the crotch portion was broken although it was usable.

[Comparative Example 1]
The kneaded paper obtained in Example 1 was slit into a width of about 3 mm and twisted at a twist number of 180 T / m to obtain 1 / 21st yarn. A twill (2/2) fabric was woven using this yarn. The warp density was 23 / cm and the weft density was 23 / cm. The cover factor is 2430.

[Comparative Example 2]
Treated 1 kg of Kumazasa leaves crushed to 5-5 mm with 180 ° C steam in a high-pressure kettle for 10 minutes, then added 4 liters of water and treated at 110 ° C for 10 minutes, filtered, concentrated under reduced pressure, and heated residue 20% Of Kumazasa extract was obtained.

In addition, a woven fabric having the same density and structure as the woven fabric obtained in Example 1 was woven using the same cotton yarn (corresponding to 1/32) as the yarn used for the Japanese paper used in Example 1.

This fabric was impregnated with a 5% by weight aqueous solution of Kumazasa extract and dried by squeezing to a squeeze rate of 200% to obtain a fabric carrying Kumazasa extract components. The obtained woven fabric was used as the fabric 8 in the form shown in FIG. The part except a crotch part used the said part of commercially available shorts (cotton knitting use).
