BEST MODE FOR CARRYING OUT THE INVENTION Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings.
FIG. 1 is an overall view of a garment 1 of this embodiment.

[Clothing 1]
As shown in FIG. 1, the garment 1 of this embodiment is a long-sleeved T-shirt. The clothes 1 are winter clothes worn by the user when the temperature is relatively low. Since the clothes 1 of the present embodiment are winter clothes, they are required to have a heat-retaining property that makes the user feel warm when worn.

A garment 1 has a body portion 2 and sleeve portions 3 . Furthermore, the garment 1 has a collar portion 4 on the upper side of the main body portion 2 and a hem portion 5 on the lower side of the main body portion 2 . The garment 1 also has cuffs 6 at the ends of the sleeves 3 opposite to the main body 2 .
In the garment 1 of this embodiment, the main body portion 2, the sleeve portions 3, and the hem portion 5 are each constructed using the same fabric 10. As shown in FIG. On the other hand, the collar portion 4 and the cuff portion 6 are made of a fabric different from that of the body portion 2 and the like. Collar 4 and cuff 6 are made of the same fabric.

In the garment 1 of this embodiment, the body portion 2, the sleeve portions 3 and the hem portion 5 are composed of 55% cotton and 45% polyester. Collar 4 and cuff 6 are composed of 70% cotton and 30% polyester.

In addition, the shape of the clothes 1 shown in FIG. 1 is not limited to this embodiment. For example, other shapes such as a shorter sleeve portion 3 and a V-shaped collar portion 4 may be used.

FIG. 2 is a schematic diagram of the fabric 10 of this embodiment.

The fabric 10 is a material for the body portion 2, the sleeve portions 3, and the hem portion 5 of the garment 1. As shown in FIG.
As shown in FIG. 2, the fabric 10 has a front side 10A and a back side 10B. Of these, the back surface 10B is the surface that faces the user's skin when the user wears the garment 1 . On the other hand, the surface 10A is the side opposite to the user's skin when the user wears the garment 1 .

Also, the cloth 10 is constructed by a knitting method called ponchi roma (ponchi de roma). The fabric 10 is made by knitting the front surface 10A and the back surface 10B at once using a knitting machine in which the needles are arranged in two rows facing each other. Punch Roma can be regarded as a weave in which double-sided knitting and bag knitting are alternately repeated.
The fabric 10 may be a knitted fabric or a woven fabric, but is preferably a knitted fabric.

Furthermore, as shown in the enlarged view of FIG. 2, the rear surface 10B of the fabric 10 of this embodiment is raised. The back surface 10B of the fabric 10 of the present embodiment has a so-called peach raised texture that feels like the skin of a peach.

FIG. 3 is a schematic cross-sectional view of the fabric 10 of this embodiment.
FIG. 4 is a schematic diagram of the back yarn 13 of this embodiment.

As shown in FIG. 3, the fabric 10 includes front yarns 11 that constitute the front surface 10A, back yarns 13 that constitute the back surface 10B, and connecting yarns 15 that connect the front yarns 11 and the back yarns 13. configured as follows. Further, the cloth 10 has a nap 17 formed on the back yarn 13 forming the back surface 10B.

(Front thread 11)
The front thread 11 is a cotton thread. In addition, the front yarn 11 has a count of 40.
Here, the count is a unit representing the thickness of yarn obtained by spun relatively short short fibers such as cotton. For example, an English count can be used for the count. The smaller the number, the thicker the thread, and the larger the number, the thinner the thread.

As shown in FIG. 3, the front yarn 11 is woven to form a plurality of loops. A plurality of loops of the front yarn 11 are formed so as to be aligned in the longitudinal direction and the lateral direction of the fabric 10, respectively. The front yarn 11 forms the surface 10A of the fabric 10 with a plurality of loops. Further, the front yarn 11 is connected to the connecting yarn 15 on the back surface 10B side.

In this embodiment, by using cotton thread as the front thread 11 of the surface 10A, the feel of the garment 1 is improved when the user picks it up, and the garment 1 looks warm. In addition, the front yarn 11 generates heat of adsorption by absorbing sweat of the user. As a result, the heat retention of the back surface 10B, which is the skin side of the user, can be further enhanced.

(Back thread 13)
The back thread 13 is a polyester thread. Further, as shown in FIG. 4, the back yarn 13 is a filament yarn constituted by a bundle of long fibers 130 elongated in one direction. The back yarn 13 of the present embodiment has a denier D of "75" and a filament F of "144".

Here, the denier D is a unit representing the thickness of one yarn. The larger the denier number, the thicker the thread, and the smaller the denier number, the thinner the thread. The denier value is the number of grams when a certain yarn is weighed as 9000 meters.
Also, the filament F is a unit representing the number of long fibers forming one thread. That is, the filament F indicates how many long fibers are bundled to form one thread. For example, in the case of one yarn having the same denier D value, the smaller the filament F value, the thicker the individual long fibers, and the larger the filament F value, the thinner the individual long fibers.

Then, as shown in FIG. 3, the back yarn 13 is knitted to form a plurality of loops. A plurality of loops of the back yarn 13 are formed so as to be aligned in the longitudinal direction and the lateral direction of the fabric 10 respectively. The back yarn 13 forms the back surface 10B of the fabric 10 with a plurality of loops. Further, the back thread 13 is connected to the connecting thread 15 on the surface 10A side.
Further, the back yarn 13 of the present embodiment is provided with naps 17 on the crest side of the loop that forms part of the back surface 10B side. The nap 17 is formed by raising the back yarn 13 forming the back surface 10B.

As shown in FIG. 4, the nap 17 is formed by partially cutting the long fibers 130 that form one back yarn 13 . Specifically, the nap 17 is formed by a plurality of long fibers 130 that are fluffy in the back yarn 13 .

In the present embodiment, about half of the long fibers 130 forming the backing yarn 13 are formed as the raised fibers 17 . Specifically, the raised fibers 17 of the present embodiment are formed by partially cutting 40% or more and 60% or less of the plurality of long fibers forming the back yarn 13 . Thus, in this embodiment, about half of the filaments 130 forming the backing yarn 13 are formed as the nap 17, thereby improving the "feel" and "heat retention" of the fabric 10. FIG.

If the nap 17 is less than 40% of the plurality of filaments forming the backing yarn 13, the texture of the fabric 10 is likely to deteriorate. Further, if the nap 17 is made up of 60% or more of the plurality of filaments composing the lining yarn 13, it is rather difficult for air to remain in the nap 17, increasing the possibility of reducing heat retention.

Further, in the fabric 10 of the present embodiment, the surface 10A (front yarn 11) is not raised. In the present embodiment, by not forming naps on the surface yarns 11 of the surface 10A, it is made difficult for dust and the like to adhere to the outer surface of the garment 1, for example.

(Connecting thread 15)
The connecting thread 15 is a polyester thread. The connecting yarn 15 is a filament yarn composed of a bundle of long fibers extending in one direction, similarly to the backing yarn 13 . The connecting yarn 15 has a denier D of "50" and a filament F of "72".

As shown in FIG. 3, the connecting yarn 15 connects the front yarn 11 forming a plurality of loops and the back yarn 13 forming a plurality of loops. At this time, the connecting yarn 15 connects the front yarn 11 and the back yarn 13 with a predetermined interval.
Further, the connecting yarn 15 of the present embodiment has a smaller denier D than the backing yarn 13, for example. The same polyester thread is used for the connecting thread 15 and the back thread 13 . Therefore, the connecting thread 15 is thinner than the backing thread 13 . By thinning the connecting yarn 15 in this manner, the air between the front yarn 11 and the back yarn 13 can be easily moved. As a result, the cloth 10 and the clothes 1 can be given softness.

Next, an evaluation test for the fabric 10 will be described.
FIG. 5 displays the evaluation results of the evaluation test of the fabric 10 of this embodiment.

In this test, a comparison was made for a plurality of fabrics 10 under different conditions.
The evaluation items are "napping", "weight", "touch" and "heat retention".
“Raised” refers to the raised state of the cloth 10 when raised. The raised state can be confirmed using, for example, a magnifying glass.
"Weight" is the weight of the fabric 10; Weight can be specified by weighing with a scale.
The “feel” is the feel of the fabric 10 on the side of the back surface 10B. The texture can be evaluated by actually touching the back surface 10B of the fabric 10 with a hand.
“Heat retention” is the difficulty of releasing heat. Heat retention can be specified by, for example, JIS L 1096 heat retention A method (constant temperature method).

Also, the evaluation was made into four grades: excellent (double circle: ⊚), good (circle: ◯), somewhat insufficient (triangle: △), and unsuitable (cross: ×).

In this test, the conditions of the front yarn 11 and the connecting yarn 15 of the fabric 10 were the same, and the conditions of the back yarn 13 were varied. Specifically, for the front yarn 11, a 40-count cotton (cotton) yarn was used. A polyester yarn having a denier D of “50” and a filament F of “72” was used as the connecting yarn 15 . Then, a plurality of combinations of back yarns 13 having different denier D values and filament F values were prepared. In addition, the rear surface 10B (back yarn 13 side) of the fabric 10 is raised.

Next, evaluation results will be described.
As shown in FIG. 5, when the denier D of the back yarn 13 was "50" and the filament F was "48" or "72", the evaluation of "weight" was excellent, but the evaluation of "heat retention" was excellent. was insufficient. When the numerical value of the denier D is relatively small, the long fibers forming the back yarn 13 become thick. As a result, it is thought that the individual naps formed became thicker and the heat retention decreased.

On the other hand, when the denier D of the back yarn 13 was "150" and the filament F was "144", "192" or "288", the evaluation of "weight" was unsuitable. Furthermore, when the denier D of the back yarn 13 was "150" and the filament F was "144", "192" or "288", the evaluation of "touch" was also unsuitable. The reason for this is thought to be that the back yarn 13 has become thicker and the back surface 10B has become rougher.

Furthermore, when the denier D of the back yarn 13 was "100" and the filament F was "72", "144" or "192", the evaluation of "weight" was insufficient. Furthermore, when the denier D of the back yarn 13 is "100" and the filament F is "72" or "192", the "feel" is also insufficient. In addition, when the denier D of the backing yarn 13 was "100" and the filament F was "192", raising was not formed and "raising" was inappropriate. It is considered that this is because the long fibers were too thin to withstand the raising process. When the denier D of the back yarn 13 was "100" and the filament F was "192", the "heat retention" was also unsuitable.

When the denier D of the backing yarn 13 was "75" and the filament F was "192", raising was not formed and "raising" was inappropriate. It is considered that this is because the long fibers were too thin to withstand the raising process. When the denier D of the back yarn 13 was "75" and the filament F was "192", the "heat retention" was also unsuitable.
On the other hand, when the denier D of the back yarn 13 is "75" and the filament F is "72" or "144", the "napping", "weight", "feel" and "heat retention" are all good or better. was evaluated.
In particular, when the denier D of the back yarn 13 was "75" and the filament F was "144", the "feel" and "heat retention" were excellent. When the denier D, which indicates the thickness of the lining yarn 13, and the filament F, which indicates the thickness of the filament, have these numerical values, the thickness of the lining yarn 13 itself and the thickness of the nap 17 synergize to achieve a "feel". ” and “heat retention” are presumed to have become excellent.

Next, manufacturing of the garment 1 of this embodiment will be described.
FIG. 6 is a diagram showing an example of the manufacturing process of the garment 1 of this embodiment.

As shown in FIG. 6, a knitting process is performed to knit the fabric 10 using the front yarn 11, the back yarn 13 and the connecting yarn 15 (S601). In the knitting process of this embodiment, a knitting machine in which needles are arranged in two rows facing each other is used. The front yarn 11 is a 40 count cotton yarn. The back yarn 13 is a polyester yarn having a denier D of "75" and a filament F of "144". The connecting yarn 15 is a polyester yarn having a denier D of "50" and a filament F of "72."

Next, a raising process is performed to raise the cloth 10 (S602). In the raising process, while moving the cloth 10 in one direction, a cylindrical sandpaper that rotates in a direction opposite to the moving direction of the cloth 10 is brought into contact with the back surface 10B of the cloth 10 . As a result, the long fibers 130 of the back yarn 13 on the back surface 10B are partially cut and stand up further. A nap 17 is formed on the back yarn 13 .
In the present embodiment, about 72 long fibers, half of the 144 long fibers 130 forming the back yarn 13 , are formed as the raised fibers 17 . In this way, about half of the filaments 130 forming the back yarn 13 are raised 17, thereby forming the fabric 10 excellent in "feel" and "heat retention".

Then, a cutting step is performed to cut the raised fabric 10 into a predetermined shape (S603). During this cutting process, the fabric 10 is formed into a shape for making the garment 1 .
Further, a sewing process for sewing the cut cloth 10 is performed (S604). Through this sewing process, the cut fabric 10 is formed into the shape of the garment 1 (see FIG. 1). When the garment 1 is formed, sewing is performed so that the rear surface 10B, which has been raised in the raising step (S602), becomes the inner surface of the garment 1 (the user's skin side).

As described above, the fabric 10 is produced from the thread, and the garment 1 is produced from the fabric 10 . In this case, the fabric 10 is manufactured to be comfortable to the touch and have high heat retention, so that the user feels comfortable when wearing the garment 1 . In addition, the heat retention when the user wears the clothes 1 is also improved.

Note that the front yarn 11 is not limited to the cotton yarn of this embodiment. When cotton yarn is used for the front yarn 11, cotton yarn of a count different from 40 count may be used. Further, for example, the same polyester thread as the back thread 13 may be used for the front thread 11 . Further, for example, the front yarn 11 may be a blended yarn composed of cotton and polyester. Even in this case, the heat retention of the garment 1 or the fabric 10 can be enhanced, and the touch of the back surface 10B can be improved.

Note that the fabric 10 of the present embodiment can be used for outerwear such as T-shirts, jackets, blousons, coveralls, coats, slacks, jeans, and skirts, or underwear such as tights, spats, and pants, as well as clothing worn on the user's body. Can be used for accessories. Further, the fabric 10 can be used for various items such as hats, socks, mufflers, and gloves.

Here, the front thread 11 is an example of the first thread. The back thread 13 is an example of a second thread. The long fibers 130 are an example of fibers. The connecting thread 15 is an example of a third thread. Surface 10A is an example of a first surface and an outer surface. Back surface 10B is an example of a second surface and an inner surface.

Various embodiments and modifications have been described above, but these embodiments and modifications may be combined.
In addition, the present disclosure is not limited to the above embodiments, and can be embodied in various forms without departing from the gist of the present disclosure.
