In the first embodiment, the fabric 10 is woven with a 3/1 twill weave, which is a kind of twill weave. As a result, on one surface of the fabric 10, as shown in FIG. 1, the exposure rate of the ordinary yarn 11 is 75%, and the exposure rate of the functional yarn 12 is 25%. Further, on the other surface of the fabric 10, as shown in FIG. 2, the exposure rate of the ordinary yarn 11 is 25%, and the exposure rate of the functional yarn 12 is 75%.

The exposure rate of the ordinary yarn 11 can be obtained according to the formula (1).

Exposure rate of ordinary yarn (%) = exposed area of ordinary yarn / (exposed area of ordinary yarn + exposed area of functional yarn) x 100 (%)
... (1)

The exposure rate of the functional yarn 12 can be obtained in the same manner.

Regarding the fabric 10 which is a woven fabric, as a method of making the area where the ordinary yarn 11 is exposed on one surface equal to or larger than the area where the functional yarn 12 is exposed, the ordinary yarn 11 and the function are used as one of the warp yarn and the weft yarn. Area where the ordinary yarn 11 is exposed on one surface when one of the sex yarns 12 is used and the other of the ordinary yarns 11 and the functional yarns 12 is used as the other of the warp and weft yarns. However, there is a method of adopting a weaving method (texture) in which the area where the functional yarn 12 is exposed or more is exposed.

In this case, the exposure rate of the ordinary yarn 11 and the functional yarn 12 on one surface of the fabric 10 can be adjusted by the weaving method.

Further, both the ordinary yarn 11 and the functional yarn 12 are mixed and used as one of the warp and weft in a predetermined ratio, and only the ordinary yarn 11 is used as the other of the warp and weft. There is a method in which the area where the ordinary yarn 11 is exposed on one surface is equal to or larger than the area where the functional yarn 12 is exposed.

Further, as the warp and weft, both the ordinary yarn 11 and the functional yarn 12 are mixed and used in a predetermined ratio, and the area where the ordinary yarn 11 is exposed on one surface is exposed to the functional yarn 12. There is a way to make it larger than the area to be used.

When one of the warp and weft, or each of the ordinary yarn 11 and the functional yarn 12 is mixed and used in a predetermined ratio, the ratio of mixing the ordinary yarn 11 and the functional yarn 12 and the ratio of the ordinary yarn 11 and the functional yarn 12 are mixed. Depending on the weaving method, the exposure rates of the ordinary yarn 11 and the functional yarn 12 on one surface of the fabric 10 can be adjusted.

In addition, the exposure rate of the ordinary yarn 11 and the functional yarn 12 on one surface of the fabric 10 can be adjusted by the thickness of each of the ordinary yarn 11 and the functional yarn 12. In the following, unless otherwise specified, the thickness of the normal yarn 11 and the functional yarn 12 is assumed to be the same.

The fabric 10 shown in FIGS. 1 and 2, and also to FIGS. 3 to 10 described later, is woven in a weaving method in which the area where the ordinary yarn 11 is exposed on one surface is equal to or larger than the area where the functional yarn 12 is exposed. It is a woven fabric made.

In the third embodiment, the fabric 10 is a woven fabric composed of a normal yarn 11 and a functional yarn 12, and is woven with a 2/1 twill weave, which is still another kind of twill weave. As a result, on one surface of the fabric 10, as shown in FIG. 5, the exposure rate of the ordinary yarn 11 is 62.5%, and the exposure rate of the functional yarn 12 is 37.5%. There is. Further, on the other surface of the fabric 10, as shown in FIG. 6, the exposure rate of the ordinary yarn 11 is 37.5%, and the exposure rate of the functional yarn 12 is 62.5%. ..

FIG. 7 is a plan view showing the structure of one surface of the fourth embodiment of the fabric to which the present invention is applied. FIG. 8 is a plan view showing the structure of the other surface of the fourth embodiment of the fabric to which the present invention is applied.

In the drawings, the parts corresponding to those in FIGS. 1 and 2 are designated by the same reference numerals.

In the fourth embodiment, the fabric 10 is a woven fabric composed of a normal yarn 11 and a functional yarn 12, and is woven with five satin weaves, which is a kind of satin weave. As a result, on one surface of the fabric 10, as shown in FIG. 7, the exposure rate of the ordinary yarn 11 is 80%, and the exposure rate of the functional yarn 12 is 20%. Further, on the other surface of the fabric 10, as shown in FIG. 8, the exposure rate of the ordinary yarn 11 is 20%, and the exposure rate of the functional yarn 12 is 80%.

FIG. 9 is a plan view showing the structure of one surface of the fifth embodiment of the fabric to which the present invention is applied. FIG. 10 is a plan view showing the structure of the other surface of the fifth embodiment of the fabric to which the present invention is applied.

In the drawings, the parts corresponding to those in FIGS. 1 and 2 are designated by the same reference numerals.

In the fifth embodiment, the fabric 10 is a woven fabric composed of a normal yarn 11 and a functional yarn 12, and is woven with eight satin weaves, which is another kind of satin weave. As a result, on one surface of the fabric 10, as shown in FIG. 9, the exposure rate of the ordinary yarn 11 is 87.5%, and the exposure rate of the functional yarn 12 is 12.5%. There is. Further, on the other surface of the fabric 10, as shown in FIG. 10, the exposure rate of the ordinary yarn 11 is 12.5%, and the exposure rate of the functional yarn 12 is 87.5%. ..

Although twill weave and satin weave have been described above as the weaving method of the fabric 10 which is a woven fabric, other weaving methods such as plain weave can be adopted as the weaving method of the fabric 10.

As the functional thread 12 constituting the fabric 10, a thread containing a hollow synthetic resin filament containing an infrared absorbing material and an ultraviolet reflecting material can be adopted.

The functional thread 12 may be composed of only one or a plurality of hollow synthetic resin filaments containing an infrared absorber and an ultraviolet reflective material, or may be composed of one or a plurality of synthetic resin filaments and optionally. It can also be configured by mixing with ordinary yarn.

The synthetic resin filament constituting the functional yarn 12 may be a monofilament made of a hollow synthetic resin material, or a multifilament which is a twisted yarn obtained by twisting a plurality of hollow synthetic resin filaments. You may.

The synthetic resin filament constituting the functional yarn 12 can be configured to include one or more synthetic resin materials of nylon, polyester, and polyurethane.

For example, since polyurethane has excellent elasticity, polyurethane yarn is used as a core material, and nylon yarn or polyester yarn is wound around the polyurethane yarn to form the functional yarn 12, so that the functional yarn 12 has elasticity. Can be given. Further, according to nylon, polyester, and polyurethane, the heat storage property can be improved.

When the functional thread 12 is composed of a plurality of threads, at least one thread may be hollow for the plurality of threads. Further, each of the plurality of threads constituting the functional thread 12 may be a monofilament or a multifilament.

As the infrared absorber and the ultraviolet reflector contained in the synthetic resin filament constituting the functional yarn 12, separate substances may be adopted, or one substance that functions as both the infrared absorber and the ultraviolet reflector. For example, a pigment (powder) can also be adopted.

When a pigment that functions as both an infrared absorber and an ultraviolet reflector is contained in a filament made of a synthetic resin, it is more functional than when a separate substance that functions as an infrared absorber and an ultraviolet reflector is contained. The production of the thread 12 can be facilitated.

As the pigment that functions as both an infrared absorber and an ultraviolet reflector, for example, a gray pigment can be adopted.

Although not confirmed at this time, if a white pigment that functions as both an infrared absorber and an ultraviolet reflective material is found, an infrared absorber to be contained in the synthetic resin filament constituting the functional yarn 12 and an infrared absorber. A white pigment can be used as the pigment as the ultraviolet reflecting material. By adopting a white pigment, color dyeing can be easily performed.

As the gray pigment (powder), for example, at least one powder selected from the group consisting of metal oxides, minerals, and inorganic substances can be adopted. Examples of the metal oxide include titanium dioxide and zinc oxide. Examples of minerals include gray mica. Examples of the inorganic substance include calcium carbonate and barium sulfate.

The gray pigment powder that functions as both an infrared absorber and an ultraviolet reflector can be contained in the synthetic resin filament, for example, by adhering to or kneading the synthetic resin filament.

By constructing the fabric 10 with the functional yarn 12 containing a synthetic resin filament containing a gray pigment that functions as both an infrared absorber and an ultraviolet reflector, the amount of infrared rays absorbed by the fabric 10 is increased. At the same time, it can block ultraviolet rays.

Further, since the synthetic resin filament contained in the functional yarn 12 is hollow and has a heat storage effect, even if one surface of the fabric 10 is cooled by cold air or the like, the temperature of the other surface of the fabric 10 is high. Can be suppressed from falling.

From the above, in the fabric 10, the other surface can be given a warm feeling and can sufficiently shield ultraviolet rays.

As the ordinary yarn 11 constituting the fabric 10, any yarn whose function and composition are not particularly limited can be adopted. Therefore, the ordinary yarn 11 can be easily colored in any color by using any dye or pigment.

As described above, since the ordinary yarn 11 can adopt any yarn and be colored in any color, by forming the fabric 10 from such ordinary yarn 11, any texture and feel can be obtained. It can be applied to the dough 10.

For example, as the ordinary yarn 11, at least one natural fiber selected from the group consisting of cotton, hair, hemp, and silk can be used. By using natural fibers as the ordinary yarn 11, it is possible to construct the fabric 10 which looks like natural fibers in appearance.

The fabric 10 is composed of the ordinary yarn 11 and the functional yarn 12 as described above, and the area where the ordinary yarn 11 is exposed on one surface is equal to or larger than the area where the functional yarn 12 is exposed. The fabric 10 can be provided with the functionality of feeling warm and sufficiently shielding ultraviolet rays without impairing the above.

That is, the appearance and texture of the fabric 10 are not impaired by the functional yarn 12, and the appearance and texture of the fabric 10 are similar to those of the fabric made of natural fibers. It can be applied to the fabric 10 by the thread 12.

Therefore, by using the cloth so that one side of the cloth 10 is the front side of the product, the appearance looks like a normal cloth, but it has a function of giving a feeling of warmth and sufficiently blocking ultraviolet rays. The dough can be provided.

Then, by sewing the cloth product using the cloth 10, it is possible to provide a cloth product that feels warm and sufficiently shields ultraviolet rays while giving a desired design to the appearance.

For example, when sewing a garment using the fabric 10, the garment can be sewn so that one side of the fabric 10 is the front side of the garment and the other side of the fabric 10 is the back side of the garment. .. In this case, it is possible to provide a cloth product having a function of giving a feeling of warmth and sufficiently shielding ultraviolet rays, while having an appearance of clothes using ordinary yarn 11.

In FIGS. 1 to 10, in the fabric 10 which is a woven fabric, the ordinary yarn 11 is used as the warp and the functional yarn 12 is used as the weft, but as described in FIGS. 1 and 2. The ordinary yarn 11 can be used as a weft and the functional yarn 12 can be used as a warp.

When the ordinary yarn 11 is used as a weft and the functional yarn 12 is used as a warp, the exposure rates of the ordinary yarn 11 and the functional yarn 12 are replaced with those described above.

Therefore, when the ordinary yarn 11 is used as a warp and the functional yarn 12 is used as a weft, the area on the front side of the fabric 10 where the ordinary yarn 11 is exposed is equal to or larger than the area where the functional yarn 12 is exposed. For example, when the ordinary yarn 11 is used as a weft and the functional yarn 12 is used as a warp, the area where the ordinary yarn 11 is exposed is larger than the area where the functional yarn 12 is exposed on the back side of the fabric 10. Become.

Further, regarding the fabric 10, the area where the ordinary yarn 11 is exposed on one surface is set to be equal to or larger than the area where the functional yarn 12 is exposed, and the area where the ordinary yarn 11 is exposed on one surface is functional. It can be larger than the area where the thread 12 is exposed. In this case, it is possible to further prevent the appearance of the fabric 10 from being spoiled by the functional yarn 12.

Further, the fabric 10 may be composed of a woven fabric (woven fabric) or a knitted fabric.

As a knitting method for knitting (knitting) a knitted fabric 10 composed of ordinary yarns 11 and functional yarns 12, plating or pulling alignment using a plurality of yarns can be adopted.

FIG. 11 is a diagram showing the structure of the sixth embodiment of the dough to which the present invention is applied.

In the drawings, the parts corresponding to those in FIGS. 1 and 2 are designated by the same reference numerals.

In the sixth embodiment, the fabric 10 is a knitted fabric composed of a normal yarn 11 and a functional yarn 12.

In the sixth embodiment, the knitted fabric 10 uses the ordinary yarn 11 as the ground yarn (front yarn) and the functional yarn 12 as the splicing yarn (back yarn), and is spliced with the ground yarn. The yarns are knitted by a plating in which the yarns are aligned and knitted so as to be lined up in the depth direction of the fabric 10.

According to the plating, the area where the ordinary yarn 11 is exposed on the front surface as one surface of the fabric 10 is equal to or larger than the area where the functional yarn 12 is exposed. That is, according to the plating, the ordinary yarn 11 as the ground yarn is exposed on almost the entire front side of the fabric 10, and the functional yarn 12 as the auxiliary yarn is exposed on almost the entire back side of the fabric 10.

Therefore, the fabric 10 can be provided with the functionality of feeling warm and sufficiently shielding ultraviolet rays without impairing the appearance of the fabric 10.

FIG. 12 is a diagram showing the structure of the seventh embodiment of the dough to which the present invention is applied.

In the drawings, the parts corresponding to those in FIGS. 1 and 2 are designated by the same reference numerals.

In the seventh embodiment, the fabric 10 is a knitted fabric composed of a normal yarn 11 and a functional yarn 12.

In the seventh embodiment, the knitted fabric 10 is knitted by pulling and knitting the ordinary yarn 11 and the functional yarn 12 so as to be aligned in the plane direction of the fabric 10.

According to the pulling alignment, for example, by using a thread having a thickness equal to or larger than the thickness of the functional thread 12 as the ordinary thread 11, the area where the ordinary thread 11 is exposed on one surface of the fabric 10 is functional. It is equal to or larger than the exposed area of the thread 12.

Therefore, the fabric 10 can be provided with the functionality of feeling warm and sufficiently shielding ultraviolet rays without impairing the appearance of the fabric 10.

It should be noted that the area of the ordinary yarn 11 and the functional yarn 12 exposed on one surface of the fabric 10 in the pulling alignment is the clue for feeding the ordinary yarn 11 and the functional yarn 12 in the knitting machine for knitting the knitted fabric. It can be adjusted by setting the number. For example, by increasing the number of clues of the ordinary yarn 11 to be larger than the number of clues of the functional yarn 12, the area where the ordinary yarn 11 is exposed on one surface is larger than the area where the functional yarn 12 is exposed. can do.

Plating and alignment can be done on any knitted fabric.

There are two types of knitted fabrics: weft knits that make stitches (loops) in the horizontal direction and warp knits that make stitches in the vertical direction. The weft knitting includes, for example, a flat knitting (tenjiku knitting), a rubber knitting (rib knitting), a pearl knitting (garter knitting), a double-sided knitting (smooth knitting), and the like. The warp edition includes, for example, the Denby edition (single god edition), the chord edition, and the atlas edition.

The fabric 10 is a knitted fabric composed of a normal yarn 11 and a functional yarn 12 in which the area where the ordinary yarn 11 is exposed on one surface is equal to or larger than the area where the functional yarn 12 is exposed. It is possible to knit without applying plating or pulling alignment.

That is, the fabric 10 which is a knitted fabric in which the area where the ordinary yarn 11 is exposed on one surface is equal to or larger than the area where the functional yarn 12 is exposed can be formed by a knitted fabric knitted with one yarn.

For example, the fabric 10 can be knitted by selecting and using the ordinary yarn 11 or the functional yarn 12 in line units as the yarns constituting the stitches made in the lateral direction in the weft knitting.

Further, the fabric 10 can be knitted by selecting and using the ordinary yarn 11 or the functional yarn 12 for each row as the yarn constituting the stitches formed in the warp direction in the warp knitting.

As the yarns constituting the stitches made in the vertical direction in the Denby knitting, the cord knitting, and the atlas knitting, the ordinary yarn 11 or the functional yarn 12 is selected and used in row units.

For example, in the warp knitted fabrics 10 such as the Denby knitting, the cord knitting, and the atlas knitting shown in FIGS. 17 to 19, the ordinary yarn 11 and the functional yarn 12 are used as the yarns constituting the stitches formed in the vertical direction. The exposure rate of the normal yarn 11 and the functional yarn 12 on one surface of the fabric 10 can be adjusted by the ratio of the rows in which each is used. For example, by setting the ratio of the rows in which the ordinary yarn 11 is used to 50% or more, the area where the ordinary yarn 11 is exposed can be made larger than the area where the functional yarn 12 is exposed.

As for the knitted fabric 10, for example, instead of the functional yarn 12 of the knitted fabric shown in FIGS. 13 to 19, a yarn obtained by mixing a normal yarn 11 and a functional yarn 12 can be used. In this case, the exposure rate of the ordinary yarn 11 and the functional yarn 12 on one surface of the fabric 10 can be adjusted by the ratio of mixing the ordinary yarn 11 and the functional yarn 12.

The fabric 10 which is a knitted fabric as described above is also composed of the ordinary yarn 11 and the functional yarn 12, and the area where the ordinary yarn 11 is exposed on (at least) one surface is larger than the area where the functional yarn 12 is exposed. By doing so, the fabric 10 can be provided with the functionality of feeling warm and sufficiently blocking ultraviolet rays without impairing the appearance of the fabric 10.

Next, the test performed on the dough 10 will be described.

In the test, polyester was melt-spun using an extruder equipped with a mouthpiece corresponding to a hollow cross section, and a multifilament formed by twisting a plurality of hollow monofilaments was produced as a functional yarn 12. In the production of the functional yarn 12, when the polyester was melted and kneaded, a powder of ceramics as a gray pigment was added to make the filament contain the gray pigment.

In the test, cotton yarn was adopted as the ordinary yarn 11, and the ordinary yarn 11 was used as the ground yarn, and the functional yarn 12 was used as the auxiliary yarn, so that the ordinary yarn 11 was exposed on the front side and the functionality was on the back side. The plain fabric was knitted as the fabric 10 by a flat knitting to which a plating for knitting the yarn 12 was applied.

As for the appearance of the plain fabric as the fabric 10, a normal polyester yarn is adopted instead of the normal plain fabric, for example, the functional yarn 12, and the normal polyester yarn and the ordinary yarn 11 are used in the same manner as the fabric 10. An appearance similar to that of the knitted Tianzhu fabric was observed.

In the test device 101, the light source 111 emits artificial sunlight, and the artificial sunlight irradiates the heat receiving bodies 112 and 113 installed below the light source 111.

One of the heat receiving bodies 112 and 113, for example, the heat receiving body 113 is equipped with a sample for evaluating the heat storage property.

In the test, a plain cloth as the cloth 10 and a normal cloth are used as the sample, and the sample is attached to the heat receiving body 113 so that the back surface of the sample is in contact with the heat receiving body 113. Therefore, the heat receiving body 113 absorbs the heat generated by the sample absorbing the artificial sunlight.

In the test, after being irradiated with artificial sunlight for 30 minutes, the rising temperatures of the bare heat receiver 112 to which nothing was attached and the heat receiver 113 to which the sample was attached were measured by the thermo camera 114. To.

Then, using the average rising temperature ΔT1 of the bare heat receiving body 112 and the average rising temperature ΔT2 of the heat receiving body 113 to which the sample is mounted, the light absorption heat generation temperature difference ΔT of the sample is expressed by the equation ΔT = ΔT2-ΔT1. It is calculated according to.

FIG. 21 is a diagram showing test results of a test for evaluating the heat storage property of a dough.

The light absorption heat generation temperature difference ΔT of the plain cloth as the cloth 10 was 15.2 degrees, and the light absorption heat generation temperature difference ΔT of the normal plain cloth was 11.4 degrees. Therefore, the difference in the light absorption heat generation temperature difference ΔT between the Tenjiku cloth as the cloth 10 and the normal Tenjiku cloth is 3.8 degrees, and the temperature on the back side of the Tenjiku cloth as the cloth 10 is higher than that of the normal Tenjiku cloth. You can confirm that it is easy to do.

A test was conducted to measure the ultraviolet shielding rate of the Tenjiku cloth as the cloth 10. In the test for measuring the ultraviolet shielding rate, the transmittance at which ultraviolet rays having a wavelength of 290 to 400 nm pass through the fabric is measured by a spectrophotometer according to JIS L 1925, and the ultraviolet shielding rate is obtained according to the formula (2).

UV shielding rate (%) = 100-Average transmittance of UV rays (%)
... (2)

The infrared (average) transmittance of the Tenjiku cloth as the cloth 10 was 0.2%, and the ultraviolet shielding rate was 99.8%. The infrared shielding rate of the 100% cotton fabric was 98.9%. Therefore, it can be confirmed that the Tenjiku cloth as the cloth 10 sufficiently shields ultraviolet rays.

A sensory test was conducted on the Tenjiku fabric as the fabric 10. The sensory test was carried out by making a long-sleeved shirt using the Tenjiku cloth as the cloth 10 and wearing this long-sleeved shirt.

It was confirmed that when the sleeves were passed through a long-sleeved shirt using the Tenjiku fabric as the fabric 10, it felt warm and had a contact warmth function. In addition, when I wore a long-sleeved shirt using the Tenjiku fabric as the fabric 10 and moved to a place exposed to sunlight, I felt clearly warmer than the Tenjiku shirt using the normal Tenjiku fabric.

The embodiment of the present invention is not limited to the above-described embodiment, and various modifications can be made without departing from the gist of the present invention.

For example, the fabric 10 may be made of a woven fabric or a knitted fabric, or may be made of a fabric other than the woven fabric and the knitted fabric, for example, a non-woven fabric.

In addition to shirts, the fabric 10 includes, for example, fabrics for clothes such as pants, work clothes, and casual clothes, fabrics for bedding such as sheets and pillowcases, fabrics for decorative items such as wristbands, and supporters such as supporters. It can be used for fabrics of cloth products that require a feeling of warmth, such as fabrics.
