Description

The present invention relates to cool clothing worn when walking or working outdoors or indoors in the summer (especially pants (slacks, also called pants (in the sense that it is not underwear)) which is clothing for the lower body). More particularly, the present invention relates to a lower-body garment having good ventilation with outside air and a knitted fabric suitably used for the lower-body garment.
The lower body garment according to the present invention is not particularly limited as long as it covers at least a part of the legs (it may be a long skirt or the like), but it particularly covers the abdomen and buttocks. So-called long trousers including a pants portion and a leg portion covering the leg portion from the crotch to the ankle, and so-called short pants including a pants portion covering the abdomen and buttocks and a leg portion covering the leg portion from the crotch to the knee. It includes (that is, length does not matter), and the usage does not matter whether it is men's trousers, women's trousers, children's trousers, student trousers, etc., and it does not matter whether it is for everyday use, business use, work use, sports use, etc.

Long pants, which is an example of lower-body clothing, include a pants section covering the abdomen and buttocks and leg sections covering the legs from the crotch to the ankles to protect the abdomen and buttocks as well as the legs.
The inside of such trousers tends to get stuffy due to the heat and water vapor emitted by the human body, making it uncomfortable. In terms of functionality, for example, natural fibers are used for fabrics in terms of fiber materials, and natural fibers such as hemp are blended with synthetic fibers or increased in proportion, while water-absorbent synthetic fibers are developed, Materials, fabrics, and the like that do not easily absorb solar heat have been developed. Weaving or knitting has also been developed for breathable fabrics or cool-feel fabrics. Furthermore, in order to obtain a refreshing feeling from a psychological aspect, efforts have been made to dye trousers and to give crispness and slackness.

Japanese Utility Model Registration No. 3173188 (Patent Literature 1) discloses cooling trousers that are cooled by taking in even a little outside air into the trousers when walking or working outdoors in summer. The cooling trousers disclosed in Patent Document 1 are provided with tuck portions on the left and right sides of the front body of the trouser body, and through holes are formed in the folded portions of the tuck portions, respectively, and mesh fabric is applied to these through holes. , respectively, are sewn on. According to this cooling trousers, the tucks of the trousers are provided with through holes in the folded back of these tucks, and mesh is provided in each of the through holes, so that they cannot be seen from the front and are visually unappealing. It has a good appearance, and one tuck is provided on each side, and the wind that enters through the through hole in the folded part of one tuck part escapes to the other tuck part and enters from the hem opening at the end of the trousers. The effect of cooling the trousers is achieved by allowing the wind to pass through the trousers through the through holes in the folded portion of the tuck portion.

Utility Model Registration No. 3173188

However, Patent Literature 1 only improves breathability by devising a structure and providing a small through hole in the tuck portion, and there is a possibility that the function and effect of cooling the inside of the trousers by letting the wind escape is not sufficient. is high. In the first place, trousers as disclosed in Patent Document 1 were developed for the purpose of expressing the function and effect of improving breathability without being conspicuous in appearance by providing hidden through holes in tucks, pockets, etc. There are limitations to solutions that change the structure of .

Hereinafter, as an example of lower-body clothing according to the present invention, trousers will be described in detail with reference to the drawings in the present embodiment. As mentioned above, the lower body garment according to the present invention is not limited to such trousers. Further, the knitted fabric according to the present invention is a knitted fabric with good breathability that is suitably used for trousers, which is an example of such lower-body clothing.
In addition, there are various structures and manufacturing methods that can be adopted for such lower body clothing and knitted fabrics with good breathability that are suitably used therefor, and the present invention is limited to specific structures and manufacturing methods. not something. That is, if it has the characteristics described later (a knitted fabric knitted with at least two types of long fibers (synthetic fibers) with different fineness and trousers using the knitted fabric in a specific part), what kind of knitted fabric and trousers. For example, the knitting yarn and knitting structure (other than the characteristics described later) of the knitted fabric that constitutes the knitted fabric with good breathability that is suitably used for trousers, and the knitting machine that knits such a knitted fabric with good breathability The type of knitted fabric may be of any type, and the method of using the knitted fabric with good breathability in a specific part of the trousers is not particularly limited (for example, using suture as a joining method (meaning that it is acceptable to use either adhesive or adhesive). Therefore, long trousers 100 and short trousers 200 and breathable knitted fabric 300, which are examples of trousers shown below, are merely examples except for features described later.

A schematic front view and a schematic rear view of long pants 100 according to the present embodiment are shown in FIGS. 1(A) and 1(B), respectively. Schematic rear views are shown in FIGS. 2(A) and 2(B), respectively.
As shown in FIG. 1, the long trousers 100 according to the present embodiment are most characterized in that a knitted fabric 300 with good air permeability, which will be described later, is provided at a specific portion (a hem portion 150, which will be described later). Other than that, it is normal long pants (slim type) with a structure that is not particularly limited. This long pants 100 includes a pants section 110 covering the abdomen and buttocks, and leg sections 120 covering the legs from the crotch to the ankles. It is also preferable that a waist portion W is provided at the opening of the pants portion 110 to prevent slipping down. A knitted fabric 300 with good breathability, which will be described later, is provided on the hem portion 150 (specific portion) of at least one (here, both) of the front body and the back body of the leg portion 120 .

Similarly, as shown in FIG. 2, the shorts 200 according to the present embodiment are provided with a knitted fabric 300 with good breathability, which will be described later, at a specific portion (side portion 250, which will be described later). Characterized by Other than that, they are normal shorts (half pants) with a structure that is not particularly limited. The shorts 200 include a pants section 210 covering the abdomen and buttocks, and a leg section 220 covering the leg from the crotch to above the knee. It is also preferable that a waist portion W is provided at the opening of the pants portion 210 to prevent slipping down. A knitted fabric 300 having good air permeability, which will be described later, is provided on at least one (here, both) of the left and right side portions 250 (specific portions) of the pants portion 210 .

In both the long pants 100 and the shorts 200, the pockets provided on the (both) sides are made of a mesh fabric (for example, the facing fabric and/or the bag fabric) to improve breathability. It is also preferable to make it a drawstring type in which a string is provided at the waist portion W and the waist is tightened with the string in order to make it look loose (without feeling oppressive) and express a cool feeling.

Next, the knitted fabric 300 with good breathability provided at a specific portion of the long pants 100 shown in FIG. 1 and a specific portion of the shorts 200 shown in FIG. 2 will be described in detail. As described above, the method of providing such knitted fabric 300 to a specific portion of long pants 100 or a specific portion of shorts 200 is not particularly limited, but here, this knitted fabric is The knitted fabric 300 is provided by sewing to the fabric other than the specific portion as a separate fabric from the fabric other than the specific portion. In addition, in the garment for the lower body according to the present invention, it is not excluded that all fabrics of the garment for the lower body are formed of the knitted fabric 300 having good air permeability.

This knitted fabric 300 with good air permeability is a knitted fabric knitted with at least two types (here, two types) of long fibers with different finenesses, and is a first synthetic fiber yarn with a large fineness (the first synthetic fiber yarn shown in FIG. 4). Each of N courses (N is a natural number of 2 or more, here N=6 as shown in FIG. 4) knitted with one synthetic fiber yarn 310) has a fineness smaller than that of the first synthetic fiber yarn 310. One course knitted with a second synthetic fiber yarn (second synthetic fiber yarn 320 shown in FIG. 4) is included. This knitted fabric 300, which is schematically knitted as shown in FIG. 4, is knitted with the first synthetic fiber yarn 310 and the second synthetic fiber yarn 320 is knitted every six courses as shown in FIGS. One course knitted by the second synthetic fiber yarn 320 is formed, and the gap formed by the second synthetic fiber yarn 320 realizes high breathability. The white arrows shown in FIG. 3 indicate one-way air flow (for example, flow from the inside to the outside of the trousers 100), which is formed by one course knitted from the second synthetic fiber thread 320. Since the structure provided is a gap, air flows in both directions, and air circulation (circulation of air between the inside and outside of the pants 100) can be generated.

More specifically, as schematically shown in FIGS. 3 and 4, the air permeability is improved by creating a gap around the second synthetic fiber thread 320, which is a thin thread. A specific comparison will be described later). If only synthetic fiber yarns of the same thickness (whether thin or thick) are knitted, the stitches become tight and it is difficult to form such gaps. As a result of knitting so that there are six courses of thick synthetic fiber thread 310 and one course of thin synthetic fiber thread 320, one course of thin synthetic fiber thread 320 forms a gap without being clogged. It is considered possible.

Furthermore, since the synthetic fiber thread 310 and the synthetic fiber thread 320 (especially the synthetic fiber thread 320) are long fibers, there is a high possibility that the gaps will be filled with fluff in short fiber cotton and wool threads. A gap can be formed without clogging one course knitted from thin synthetic fiber thread 320 which is a long fiber.
In addition, since the number of courses of the thick synthetic fiber yarn 310 is larger than the number of courses of the thin synthetic fiber yarn 320, the knitted fabric 300 does not lose its stiffness, and the knitted fabric 300 is not a woven fabric but a knitted fabric. Therefore, it has extremely high stretchability (elasticity) (especially in the warp (vertical) direction and weft (horizontal) direction with respect to the fabric) (without using elastic yarn such as polyurethane yarn).

Here, preferably, this N is 4 or more and 8 or less. Within this range of N, it is possible to achieve good breathability (and stretchability mainly due to being in the knitted fabric) without losing stiffness.
Further, it is preferable that the fineness of the first synthetic fiber thread is 100, and the fineness of the second synthetic fiber thread is 50 or more and 90 or less. Within this range, it is possible to achieve good breathability (and stretchability mainly due to being in the knitted fabric) without losing stiffness. In particular, the first synthetic yarn 310 is a 90 denier filament yarn and the second synthetic yarn 320 is a 75 denier filament yarn, as described below. Adopted as an example.

Also, the first synthetic fiber thread 310 and the second synthetic fiber thread 320 are preferably polyester filament thread. Unlike short fibers, the polyester long fiber yarn does not become fuzzy, and the course knitted with the second synthetic fiber yarn 320 can form gaps to achieve good breathability. It is possible to realize high stretchability by knitting with fiber yarn).
Moreover, it is preferable that this knitted fabric is knitted by plain knitting. With flat knitting, in addition to being able to achieve high stretchability due to knitting, it is knitted without using "tucks", "mistakes", etc. It can be preferably adopted for trousers and the like as outdoor wear.

Here, in the example described above (N=6, 99.99 decitex (90 denier) polyester filament yarn is adopted for the first synthetic fiber yarn 310, and the second synthetic fiber yarn 320 is 83.325 decitex (75 denier) polyester filament yarn is adopted and flat knitted fabric 300) is flattened only with 99.99 decitex (90 denier) polyester filament yarn, which is the first synthetic fiber yarn 310. Breathability was compared using a knitted fabric as a comparative example. For air permeability comparison, air permeability (volume of air passing per unit area and per unit time: cm ³ /cm ² ·s) according to the Frazier method defined in JIS L 1096 was used. As a result, the example was 64.7 and the comparative example was 47.9. It has been found that the knitted fabric 300 can be realized. In addition, a plurality of knitted fabrics according to Examples and comparative examples were knitted under the same conditions, and the air permeability test by the same Frazier method was repeated. It was confirmed that good air permeability of 120% to 150% can be achieved.
As a result of adopting the knitted fabric 300 having such features for the lower body garments (the long pants 100 and the shorts 200), these lower body garments exhibit the following remarkable effects.

(1) Stretchability Since the knitted fabric 300 is not a woven fabric but a knitted fabric knitted from polyester filament yarns, it has high stretchability, especially in the warp (longitudinal) direction and weft (horizontal) direction with respect to the fabric. It has stretchability (without using elastic threads such as polyurethane threads). Furthermore, (although it is not a comparison with the woven fabric), the 2-way stretch of nylon yarn (meaning that it has stretchability in both the vertical and horizontal directions), whereas the knitted fabric has a stretchability of about 130% in both the vertical and horizontal directions, The knitted fabric 300 has a stretchability of about 170% in both length and width. In this respect, the knitted fabric 300 has high stretchability not only for the woven fabric but also for the nylon yarn 2-way stretch knitted fabric. In addition, the lower body clothing that uses such a highly stretchable knitted fabric also has excellent stretchability and has good followability to the movements of each joint during movement, so that each joint can be used. Discomfort such as pressure can be reduced. In particular, discomfort such as a feeling of pressure in each joint when moving the lower body, which is noticeable in long pants, is noticeable due to the knitted fabric 300 with high stretchability compared to the woven fabric and nylon thread 2-way stretch knitted fabric. can be reduced.

(2) Breathability In the knitted fabric 300, one course knitted with the second synthetic fiber yarn 320 is formed for every N courses knitted with the first synthetic fiber yarn 310, and this second synthetic fiber yarn The gap formed by 320 can achieve high breathability. Therefore, it is well ventilated and cool. More specifically, the inside of trousers (especially long trousers) tends to be stuffy and uncomfortable due to the heat and water vapor emitted by the human body. Since the air is circulated (exchanged) between the trousers, it is possible to obtain cool trousers that are not stuffy.

(3) UV blocking property As described above, cool lower-body clothing that does not get stuffy due to its good breathability is often worn in summer. It is preferable in that it is possible to block ultraviolet rays and prevent sunburn by imparting a UV cut function to the fabric forming the clothing for the lower body.
As described above, the lower-body garments (the long pants 100 and the shorts 200 using the knitted fabric 300) according to the present embodiment are cool and comfortable due to good ventilation with the outside air. In addition, it is easy to move because of its high stretchability.

It should be noted that the embodiments disclosed this time should be considered as examples in all respects and not restrictive. The scope of the present invention is indicated by the scope of the claims rather than the above description, and is intended to include all modifications within the meaning and range of equivalents of the scope of the claims.

INDUSTRIAL APPLICABILITY The present invention is suitable for cool lower body clothing worn when walking or working outdoors or indoors in the summer, and is ventilated with the outside air by adopting a knitted fabric having a characteristic structure. It is particularly preferred in terms of improving the properties.
