DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to underwear and clothing fabrics for sleeping or hospital wards such as pajamas. More specifically, the present invention is made of a high-density woven fabric using special yarns of weft and warp, and can have a so-called amenity effect (comfort effect) such as heat retention and moisture retention from its structural characteristics. The present invention relates to a cloth for underwear and clothing for sleep or hospital ward, which has excellent moisture retention.

[0002]

2. Description of the Related Art Conventionally, high-quality cotton yarn has been practically used as a material for high-density woven fabrics. However, high-quality cotton yarn is generally expensive, and weaving using high-quality yarn is difficult. Knits and the like have drawbacks such as a feeling of ground thickness.

[0003] Accordingly, as a material for high-density woven fabrics, a technique for producing a long fiber yarn (filament yarn) of synthetic fibers has been developed. For example, the use of an ultrafine filament yarn has been studied. However, woven fabrics using extra-fine filament yarns have problems such as a feeling of paper-like texture and lack of surface quality such as luster, and have not been put to practical use at present.

[0004] Specifically, for example, Japanese Patent Application Laid-Open Nos. 57-117647 and 58-76569 have disclosed a fibril having a specific cross-sectional shape in order to improve the feeling and gloss. By performing a special chemical treatment using a modified composite filament yarn, a method of fibrillating it into ultrafine fibers has been proposed.
This method is not practical in terms of cost, equipment, and the like because it requires special chemical treatment.

On the other hand, pajama cloths are usually made of cotton having good breathability and good water absorption for healthy people from the demand of comfort. However, for patients with skin disorders, for example, patients with allergies, the pajamas made of fabric pursuing comfort as described above may cause discomfort with significant itching because the skin surface is dry. May give. In such a case, it is more comfortable to maintain an appropriate humidity when wearing pajamas.

[0006]

It is an object of the present invention to provide a sleepwear or ward underwear / clothing fabric suitable for a moisturizing pajamas or the like which can maintain a so-called amenity effect.

Another object of the present invention is to provide the above-mentioned fabric,
For example, an object of the present invention is to provide sleepwear or ward underwear / clothing that pursues comfort for allergic patients and the like.

[0008]

[0010]

BEST MODE FOR CARRYING OUT THE INVENTION The sleeping or ward underwear / clothing fabric and the moisturizing underwear / clothing of the present invention will be described in more detail below.

In the underwear / clothing cloth for sleeping or ward according to the present invention, the weft has a single fiber denier of 0.5.
The ultra-fine polyester filaments having a denier of less than or equal to the denier include ultra-fine polyamide filaments having a denier of not more than 0.5 denier, while the warp is composed of filaments having a single-fiber denier larger than the ultra-fine polyester filaments and the ultra-fine polyamide filaments constituting the weft. It is composed of multifilament yarn.

[0012] The weft used in the present invention can be suitably obtained from a fibrillated type composite fiber filament yarn or a sea-island type composite fiber filament yarn.

In the case of using a fibrillated composite fiber filament yarn, for example, a polyester component and a polyamide component are preferably 0.05 to 0.95: 0.95 to 0.05
And a fibrillated composite fiber filament yarn formed by joining one component and the other component in a shape extending radially in at least two directions from the center of the fiber cross section at a joining ratio of A yarn containing a filament having a denier of 0.5 denier or less is used.

In the case of using a sea-island type composite fiber filament yarn, for example, a polyester component and a polyamide component are preferably 0.05 to 0.95: 0.95 as an island component extending in the fiber length direction of the sea-island type structure. The sea component of the sea-island type composite fiber filament which is mixed and arranged at a ratio of ~ 0.05 is used, and a yarn composed of an ultrafine polyester filament and an ultrafine polyamide filament having a single fiber denier of 0.5 denier or less is used. .

In the present invention, particularly, in order to obtain a high-density woven fabric, for example, the polyester component and the polyamide component in the fibrillated conjugate fiber used as the weft are:
It is desirable to use a yarn that constitutes a high shrinkage component and a low shrinkage component, each of which produces a shrinkage difference of 10% or more due to rapid heat treatment in boiling water. And particularly preferably,
The high shrinkage component consists of polyester and the low shrinkage component consists of polyamide.

After the fibrillated type composite fiber filament yarn is divided into the respective components, it is important for the realization of a high-density woven fabric that the single fiber denier be a weft containing filaments of 0.5 denier or less. . In addition, fibrillation of low shrinkage component (division into each component in conjugate fiber)
The subsequent single fiber denier is preferably 0.5 denier or less. As described later, it is important that a multifilament yarn having a single fiber denier larger than the single fiber denier after the above-mentioned weft filament yarn is fibrillated is used for the warp.

The filament yarn constituting the weft of the present invention is produced as a yarn by subjecting it to stretching or drawing twisting as in the case of ordinary synthetic fibers, but this yarn is further subjected to bulkiness. Is preferable in order to further improve the texture of the obtained fabric. For example, as the bulking processing, a false twist crimping processing capable of obtaining a false twisted yarn having a loop or a coil, or a bulk processing by a fluid processing processing capable of obtaining a loop yarn or the like is preferable. In the above-mentioned manufacturing method, false twisting may be performed during stretching, or loop yarn may be formed by air treatment after stretching and temporary twisting.

In particular, the above-mentioned fibrillated conjugate fiber will be described in detail. The rapid heat treatment in boiling water means that the fiber is instantaneously put into boiling water for treatment, and steam is applied before immersion in boiling water. This is a different concept from the case where the temperature is gradually increased while being applied to the treatment. In addition,
Dry heat treatment may be performed instead of boiling water, but the treatment effect tends to be slightly reduced. When the difference in shrinkage between the high shrinkage component and the low shrinkage component due to the rapid heat treatment is, for example, 10% or less, fibrillation is unlikely to occur, so the larger the difference in shrinkage, the better. Especially, bulky processing is applied to the fibrillated yarn. This has a further effect on increasing the bulk after fibrillation.

As a method for examining the degree of the shrinkage difference, both components can be decomposed and the residual elongation or the rate of increase in fineness can be measured.

In such a fiber, the combination of the high shrinkage component and the low shrinkage component constituting the composite fiber includes polyester and polyamide, polybutylene terephthalate and polyamide, and high shrinkage polyester such as isophthalic acid copolymer and polyamide. Combinations are preferably used.

In this case, the ratio between the polyester component and the polyamide component is preferably in the range of 0.05 to 0.95, and the cross-sectional shape of the fibril can be easily formed due to the difference in the properties of the two components. Specifically, it is composed of a component of one component and a component of the other component having a shape radially extending from the center in at least two directions, and is composed of a segment of one component joining segments of the other component. It is preferable to use one.

Next, FIG. 1 shows an example of a model structure of a multifilament yarn constituting a weft. (A) to (d) in FIG.
FIGS. 2A to 2D are model cross-sectional views showing four examples of the structure of a fibrillated conjugate fiber used as one embodiment of the present invention. FIGS. FIG. 4 is a model cross-sectional view showing four examples of the structure of the fibrillated conjugate fiber after fibrillation, wherein A is a polyester component as a high shrinkage component, and B is a polyamide component as a low shrinkage component.

In the present invention, the arrangement of the polyester component A and the polyamide component B may be reversed, but the shrinkage difference effect may be reduced. Single fiber denier of at least one component such as a low shrinkage component after fibrillation is 0.5%
d or less, more preferably 0.1 d or less. By using such an ultra-fine filament yarn, a composite bulky yarn having a soft peach skin touch and a spun like feel can be obtained.

Examples of a method for performing bulk processing on the multifilament yarn constituting the weft include false twist crimping and fluid turbulence processing as described above. In the case where more stretchability is to be obtained, the latter fluid turbulence processing is suitable. In order to give a slightly more “bulging” feeling, it is preferable to perform interlace confounding processing.

A preferred production method for obtaining the above-mentioned fibrillated conjugate fiber is, for example, a spinning speed of 25%.
A high-oriented fibrillated composite filament undrawn yarn or incompletely drawn yarn composed of polymers having different Tg temperatures (glass transition temperatures) spun at a speed of at least 00 m / min is converted to a Tg temperature of the polymer having a higher Tg temperature or lower. , Tg
Stretching at a temperature equal to or higher than the Tg temperature of the polymer on the lower temperature side.

Next, an example of a method for producing a fibrillated composite fiber will be described in more detail. First, an unoriented or incompletely oriented fibril-type composite filament spun at a spinning speed of 2500 m / min or more at a high speed. Use The spinning speed varies depending on the combination of the composite components. For example, in the case of polyester and polyamide, 2500 m
If it is less than / min, winding failure due to swelling of the polyamide component is likely to occur, and insufficient shrinkage of the polyester component tends to occur at ultra high speed spinning at 8000 m / min or more. In addition, undrawn yarn or incompletely drawn yarn, respectively in the synthetic fiber industry, usually,
It is a yarn called UY or POY.

For example, when a polyamide having a Tg temperature of room temperature or lower and a polyester having a Tg temperature of 70 to 90 ° C. are combined, the stretching temperature is optimally around 70 ° C .; The shrinkage rate of the shrinkage component polyester decreases. On the other hand, when the stretching temperature is close to room temperature, the effect of setting the polyamide is reduced, so that it is susceptible to a change in room temperature, which is not preferable for obtaining a shrinkage difference of a certain level or more. This stretching temperature can also serve as a false twist heat setting temperature when the false twisting is performed simultaneously with the stretching.

The draw ratio is preferably as high as possible in order to increase the shrinkage of the polyester. The draw ratio also depends on the spinning speed. For example, a draw speed of 1.8 to 2.0 times for a spun yarn of 3500 m / min. Is suitable. The effect of fibrillation is smaller as the stretching ratio is lower. Such a draw ratio can be applied even when performing false twisting simultaneously,
The above-mentioned stretching ratio is equivalent to the ratio performed in the normal false twisting during stretching. In addition, the number of false twists in the false twisting process, the number of false twists performed in the normal stretch false twisting process,
For example, if it is 75 denier, 3,300-3,600T /
m is suitable.

In the present invention, as a bulking method other than false twisting, air treatment can be performed. For example, spinning speed 2500 before air treatment
The unoriented or incompletely oriented yarn of the highly oriented fibrillated composite filament spun at high speed at m / min or higher is set at a temperature not higher than the Tg temperature of the polymer having a higher Tg temperature and not lower than the Tg temperature of the polymer having a lower Tg temperature. The drawing process is performed once, and then a turbulent fluid treatment or an interlaced interlacing process is performed to obtain a so-called "taslan" yarn having a ring or slack or a bulky processed yarn called an interlaced yarn.

When performing the fluid turbulent flow treatment, it is a so-called "taslan" type nozzle, and the turbulent flow pressure is preferably 3 to 8 kg / cm ² which is generally used. As described above, such a composite fiber is subjected to bulk processing in the state of a filament yarn to form a bulk yarn, and by using this for a woven fabric, a soft feeling is obtained by the countless coils and loops protruding from the woven fabric surface. A spun-like high-density woven fabric with a rich texture, drapeability, tightness, stiffness, and softness, with a spun touch on the fabric surface, and a fibrillated conjugate fiber. After fibrillation, the single fiber denier generally becomes 0.5 denier or less, so that a cotton-like feel is given. In addition, the appearance is similar to conventional filament-like, with little luster that lacks `` tekari '' or `` wax ''-like dignity, becomes a mild and deep natural luster, enough to give the image of luxury goods Gain.

Regarding the density of the woven fabric, it is natural to increase the warp and weft densities in order to obtain a high-density woven fabric. When filament yarns are used, shrinkage after fibrillation, shrinkage of the fabric, and the development of bulkiness can provide a higher-density woven fabric even if the woven density is not necessarily so high, so special weaving conditions need to be taken. It does not necessarily have the advantage that weaving design and weaving work are easy.

In the present invention, in order to make the above-mentioned shrinkage ability of the weft better exhibited, and to increase the weft bending (about the degree of bending of the weft) due to the shrinkage of the fabric, thereby increasing the density. It is particularly preferable that the woven fabric is constituted by a plain weave structure.

On the other hand, as the warp, a multifilament yarn comprising a filament having a single fiber denier larger than the ultrafine filament constituting the weft is used.

The single fiber denier of the filament constituting the warp of the present invention is preferably about several deniers, for example, 0.6 to 5 deniers, in order to realize the above-mentioned weft bending effect well. In this case, the total denier of the warp is preferably, for example, 20 to 150 denier. In addition, the total denier of the weft is preferably equal to or larger than the total denier of the warp by about 2 to 3 times, and is preferably thicker than the warp in the sense of promoting the above-described effect. The single-filament denier of the filaments constituting the weft is preferably 0.1%.
It is 01 to 0.5 denier.

As the filaments constituting the warp, polyamide multifilaments or polyester multifilaments are preferably used, and these can be combined or twisted and used together.

The woven fabric used for the underwear / clothing fabric for sleeping or ward according to the present invention is preferably a plain woven fabric by the combination of the above-mentioned weft and warp, but this fabric is shrunk in the weft direction. At that time, the component having a small shrinkage ratio in the weft is, for example, a single fiber denier of 0.5 denier or less after fibrillation and is extremely thin, and the warp has a fibril after the weft filament yarn is fibrillated. By using a multifilament yarn having a single fiber denier larger than a single fiber denier, the weft bend due to shrinkage of the fabric becomes larger (the low shrinkage component in the weft is thinner than the warp component filament, so the weft The side is more bendable and the weft filaments exhibit a greater weft bend than the warp, resulting in fabric shrinkage).

The woven fabric of the present invention has a cover factor
It is particularly preferably from 1,700 to 2,200 in order to achieve the effect as the pajama fabric of the present invention. A more preferred cover factor is between 1,800 and 2,100. If the cover factor is too small, the air permeability and moisture permeability will increase and it will not be possible to retain moisture, and if it is too large,
The air permeability and the moisture permeability are low, and the stuffiness tends to increase, resulting in a lack of comfort.

Here, the cover factor is defined as follows.

Cover factor = warp yarn density (books / inch) x (total warp yarn denier) ^1/2 cover factor = weft yarn density (books / inch) x (total weft yarn denier) ^1/2 cover factor Can be expressed by the vertical / cover factor and the horizontal / cover factor alone, or by the average value of both.

In the present invention, by adopting such a high-density woven fabric structure, an appropriate humidity can be maintained in clothes such as pajamas, and the above-mentioned object can be highly achieved. In this way, higher densification is achieved, and a moisturizing structure is formed by such a woven structure.

The sleeping or ward underwear / clothing fabric of the present invention, such as pajamas, has a test pressure of 12.7 m.
m air column Pa (cc / m ² / sec) and test pressure 30 mm water column Pb (cc / m
² / sec) are 10 ≧ Pa ≧ 0.2 and 2
5 ≧ Pb ≧ 1 and moisture permeability R (g / m ² · 24
hrs) preferably satisfies 13,000 ≧ R ≧ 9,000. If the air permeability and the moisture permeability are too small, when the pajama is tailored, it will be moisturized but unpleasant and cause discomfort, and if too large, the moisture will be inferior. Like this. By using the fabric of the present invention, appropriate humidity can be maintained in clothes such as pajamas.

The underwear / garment fabric for sleep or hospital ward according to the present invention can be made into a spun-like fabric having a good texture by using a bulky weft yarn.

The fabric of the present invention can be tailored to be used on all parts of the product to be sewn using the cloth, or partially when necessary.

The sleeping or ward underwear / clothing fabric of the present invention includes, in addition to pajamas, clothing that also needs moisture retention, such as underwear, negligee, sleepwear and patient wear.
