Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an impermeable slacks and suit having extremely high air permeability.

[0002]

2. Description of the Related Art Conventionally, as fabrics for summer suits,
Woven fabrics made from a mixture of hemp, cotton, wool, polyester, etc. are used, and the weave is coarser and thinner than autumn / winter suits. Also for the lining,
Breathable, open-woven fabrics, mesh, tricot, etc. are used.

As clothing that can be worn cool in the summer, a refreshing jacket (Japanese Utility Model Laid-Open No. 1-149486), a summer suit (Japanese Patent Laid-Open No. 3-82802), a breathable slacks and its ventilator (Japanese Patent Laid-open No. JP-A-57-176202) and the like are disclosed.

[0004]

The object of the present invention is to indirectly reduce energy consumption in summer and to reduce carbon dioxide gas, NO _x , SO _x, etc. by using fossil fuels associated therewith. The aim is to provide summer clothing with excellent cooling properties that is friendly to the environment and is called pollution prevention.

On the other hand, the culture of wearing clothes and enriching our lives is widespread and closely related to our lives. However, despite the fact that many clothes that are warm in winter are found in the market, it is extremely rare to wear formal clothes that are cool in summer. Therefore, the phenomenon that the maximum power consumption is shown in the summer day appears, and one of the causes is the power consumption of the cooler. That is, it is a major cause of indirect damage to the global environment.

A direct object of the invention is thus to improve the coolness of summer clothing. In order to improve the coolness of clothes, it is necessary for the fabric to have high air permeability, and for that purpose it is naturally necessary to use a coarsely textured fabric.However, when a coarsely textured fabric is applied, there is a fatal problem that it becomes transparent and unsightly. It was In addition, although she does not care about see-through for jackets, see-through for slacks was a particular problem. Also, from the fact that I do not mind a little see-through, many ideas have been devised and implemented for improving the coolness of outerwear, but regarding slacks, it must be assumed that it is not see-through, It is difficult to improve the refreshing property because it also needs to be retained, and it is the current situation that it has not been devised.

SUMMARY OF THE INVENTION The present invention has solved many contradictory problems at the same time, and an object of the present invention is to provide a slacks and a suit which have a high cooling property when worn and can be comfortably worn in the summer when there is little sheer.

[0008]

[Means for Solving the Problems] With respect to the above object, the present inventor has arrived at the present invention as a result of extensive studies. The outline is as follows.

[0009]

The present invention will be described in more detail below.

The slacks according to the present invention are JIS-L.
In 1096 (Fragile method), the ventilation of the knee is 50 cm ³ / cm ² · sec or more and 600 cm ³ / cm ² · sec
Less than 35cm ³ / cm of ventilation of the waist including pockets
^The basic configuration requirement is that the range is ² sec or more and 300 cm ³ / cm ² sec or less. This is because it is considered that the content within the above range is necessary in order to obtain a comfortable wearing feeling while preventing see-through.

FIG. 1 is a perspective view showing an example of a slacks according to the present invention as a model, in which a is a waist portion including a pocket portion, b is a knee portion, c is a knee and is above or below a hem. A portion, d is a pocket portion, and e is a waist interlining portion.

The slacks are not a problem of fashion or fashion, but it is premised that the slacks are not transparent, so it is difficult to place importance on comfort regarding the coolness. for that reason,
It has been considered unavoidable to thicken the front and back fabrics and even the interlining to prevent sheer and improve shape retention. The thick, non-transparent fabric naturally has poor breathability. Furthermore, if the lining and interlining are thickened, the weight of the entire slacks will increase. It is hard to say that wearing heavy and poorly breathable clothing is burdensome and comfortable.

The knee portion shown in FIG. 1b, which is an example of the slacks according to the present invention, is substantially composed of a front cloth and a back cloth.
In general, it is composed of a single sheet, and the ventilation volume is 50 cm ³ / cm in order to prevent see-through and get a comfortable wearing feeling.
It is necessary that ² · sec or more and is 600 cm ³ / cm less than ² · sec. More preferably 100 cm ³ / cm ² · s
It is ec or more and 250 cm ³ / cm ² · sec or less.

As shown in FIG. 1a, which is one example of the slacks in the present invention, the waist portion including the pocket portion is, as shown in the drawing, a pocket other than the front cloth and the back cloth, and further, a breathable material such as an interlining material. The breathability of the waist is not limited to the front and back fabrics. The ventilation amount of the waist portion including the pocket portion in the present invention means the ventilation amount of the sewn product including all the pockets, interlinings, etc. in addition to the front and back fabrics, and is not less than 35 cm ³ / cm ² · sec and 300
It is necessary to be within the range of cm ³ / cm ² · sec or less,
Preferably 50 cm ³ / cm ² · sec or more and 200 cm ³ /
The range is cm ² · sec or less.

The gauze and the gauze used in the present invention are well known cloth materials in the Japanese dressing industry. The present invention uses the cloth for clothes, and also weaves it in a wide width, and although it may be accused of being insane in the industry, it does not hinder the effectiveness of the present invention. Here, the meanings of gauze and gauze are the well-known woven structure in the industry as described above, and therefore the description thereof is omitted. In particular, as the gauze or gauze fibers applied for this purpose, gauze or gauze using multi-lobal cross-section fibers such as the commonly known cross section of polyester, T-shaped cross section is preferable, and such a woven fabric is subjected to weight reduction processing. Those that are present are preferable. Further, it is preferable that the tip of the multi-lobal cross section has a wedge-shaped neck. The reason is that it is easy to avoid misalignment, and the texture gives a smooth feel for summer,
Furthermore, it does not have a waxy feel and can express a high-quality luster and luster. In addition, dimensional stability is important for light and open clothes such as this cloth, and gauze or gauze is easy to satisfy. Further, in order to obtain a preferable breathability while preventing the see-through, the thickness of the warp yarn and the weft yarn of the gauze or the gauze is 30
In the range of yarn use from denier to 200 denier,
It is preferable that the warp yarn density is 30 yarns / inch or more and less than 120 yarns / inch, and the weft yarn density is 10 yarns / inch or more and less than 70 yarns / inch or more. Furthermore, the warp yarn density is 45 yarns / inch or more and 100 yarns / inch or more. More preferably, the weft density is less than 25 yarns / inch and less than 55 yarns / inch.

The twist of the warp yarn and the weft yarn is 500 T / m or more and less than 3500 T / m in the case of a single yarn, and the lower twist is 500 T / m or more and 3500 in the case of more than two yarns.
Less than T / m, upper twist of 300 T / m or more and 2000 T
It is preferably less than / m in order to prevent misalignment and to make the texture feel smooth for the summer. Furthermore, in the case of single yarn, 800 T / m or more and less than 3000 T / m, and in the case of twin yarn or more, the ply twist is 800 T / m or more and 3 or more.
Less than 000 T / m, upper twist is 500 T / m or more and 15
More preferably, it is less than 00 T / m 2.

Furthermore, in order to satisfy the contradictory performances of preventing see-through and obtaining preferable air permeability, the porosity of the above-mentioned gauze or gauze fabric alone is within the range of 15% or more and less than 60%. It is necessary to exist, and the range of 20% or more and less than 55 is more preferable. The porosity is measured by a device for expanding the material (for example, a video microscope manufactured by Sony Corporation).
The magnified photograph is taken at 5 or more places, and the value of the area of the aperture (the area where no fiber exists) / the area of the fabric is measured, and the average value is obtained.

The backing material used for the slacks of the present invention has a porosity of 5% or more in the above-mentioned measuring method in order to satisfy the contradictory performances of preventing see-through and obtaining preferable air permeability. And it is necessary that the content is less than 50%, but it is more effective and preferable if it is 7% or more and less than 25%. The basis weight of the lining fabric is 25 g / m
It is necessary that the amount is ² or more and less than 115 g / m ² , but 40 g / m ² or more and less than 100 g / m ² is more preferable.

The lining material of the slacks in the present invention is required to be a yarn which is subjected to false twisting and further subjected to strong twisting of 1000 times / m or more and less than 3100 times / m. It is more effective and preferable that twist processing is performed and reverse twist is performed at 1500 times / m or more and less than 2800 times / m.

The false-twisting process generally means a process in which a twisting treatment is performed in a state where a strong twist is applied to a raw yarn, and a reverse twist is applied thereto. In addition, the fabric made of yarn that has been subjected to false twisting and strong twisting has a soft surface feeling, yet has a firm and elastic feel, and also has a unique refreshing crispness and a cool and refreshing feel. is there.

The slacks knee portion in the present invention is as shown in FIG. 1b, and the portion above the knee portion and above the hem or the hem is as shown in c. Since the lining material of the slacks of the present invention extends below the knee portion and above the hem or extends to the hem, there is substantially no portion of the slacks that constitutes one front material. As a result, see-through can be prevented and the slacks are not unsightly and easy to wear.

The waist interlining in the present invention refers to a portion shown in FIG. 1-d, and is used for a waist portion including a thick lining and a belt core, which are generally called waist lining. It is a general term for items for the purpose of improving shape retention and wearing comfort.

The waist interlining has a porosity of 15
It is preferable to use lace knitting that is at least%. As a result, the breathability can be kept high, the weight can be reduced, the form can be stabilized, and the underwear can be prevented from adhering to the skin, and a dry feel can be expressed. The porosity of such lace knitting is measured by the same method as the above-mentioned porosity measurement, and is determined by the average value thereof. To make the effect of the present invention more effective, the porosity is 15% or more. It is preferable, but 20% or more is more preferable. Russell lace is preferably applicable to such lace knitting. Further, as the Russell lace, a turtle shell or a modified turtle shell is particularly preferably applicable to the present invention and the effect can be enhanced.

The present invention is also characterized in that it is possible to realize extremely lightweight men's clothing, and the average size is AB.
-4 (height 165 to 167 cm, waist circumference 94 cm, waist circumference 84 cm), slacks alone weighs 750 g
It is preferably less than 500 g, more preferably less than 600 g, particularly preferably less than 500 g.

The slacks according to the present invention and the surface material are substantially gauze or gauze, and the number of warp threads of gauze or gauze is 30 or more and less than 120 per inch.
The number of weft threads is 10 or more and less than 70 / inch, and the porosity of the fabric alone is 15% or more and 60% or more.
It is more preferable to combine an outerwear using a fabric that is less than the above and wear it as a suit rather than to wear the slacks alone because the effect of the present invention is more exerted. Furthermore, the suit according to the present invention, which has a feature that an extremely lightweight men's clothing can be realized, has an average size of AB-4.
(Height 165 to 167 cm, waist 94 cm, waist 8
4 cm), the total total weight is preferably less than 1000 g, particularly preferably less than 900 g.

The slacks and suit of the present invention having the above-mentioned constitution can be preferably applied as a formal suit and further to a casual suit, a blazer or the like.

EXAMPLES The present invention will be described in more detail below with reference to examples.

Example 1 The slacks of the present invention were sewn using the following materials.

Surface fabric: weave: gauze fiber: warp and weft 100% polyester
Strongly twisted yarn of triangular cross-section fiber (twist number: lower twist 1500 T / m, upper twist
900T / m) Warp thread density: 81 threads / inch Weft thread density: 38 threads / inch Porosity: 42.3% Unit weight: 105 g / m ² Lining ... Knitting: Thin plain weave Fiber: Warp And weft 100% polyester,
Processed thread 75D / 36F (36 filament 75 denier) Vertical thread density: 90 threads / inch Horizontal thread density: 93 threads / inch Porosity: 8.6% Weight: 70 g / m ² Post-processing: sweat absorption, quick drying , Antifouling processing ・ Interchangeable fabric… Change Kamekosa knitting Fiber: Nylon 100% Porosity: 23.2% Unit weight: 196 g / m ² Example 1 and wool 60% polyester 40% for outer material A summer slacks (comparative example) that has been commercially available from the past was worn outdoors to examine the coolness. The day when I wore it was a very hot day with strong sunlight, and when I wore the comparative example, the fine lining was used on the entire surface to prevent see-through even though it was for summer, so the see-through was Although it was not observed, the outer fabric itself was thin, but the dense lining was used, so breathability was poor and heat was trapped inside the clothes, and the lining stuck to the bare skin due to sweat, which made me feel very uncomfortable. When the suit of the example of the present invention was worn, it was almost transparent and the breathability was improved, so that it was cool and comfortable to wear without heat buildup. Moreover, since it is extremely lightweight, it does not put a strain on the body and does not feel tired even after being worn for a long time.

Example 2 A suit of the present invention was sewn using the following materials.

Surface fabric: weave: gauze fiber: 100% polyester for both warp and weft
Strongly twisted yarn of triangular cross-section fiber (twist number: lower twist 1500 T / m, upper twist
900T / m) Warp thread density: 68 threads / inch Weft thread density: 37 threads / inch Porosity: 49.2% Unit weight: 85 g / m ² Lining ... Knitting: Thin plain weave Fiber: Warp And weft 100% polyester,
Processed thread 75D / 36F (36 filament 75 denier) Vertical thread density: 90 threads / inch Horizontal thread density: 93 threads / inch Porosity: 8.6% Weight: 70 g / m ² Post-processing: sweat absorption, quick drying , Antifouling process ・ Interlining ... Knitted gauze knitting Fiber: Nylon 100% Porosity: 23.2% Unit weight: 196 g / m ² Example 1 and 70% wool 30% polyester for outer material At the present time, the coolest summer suit (comparative example) was measured by comparing the ventilation amount of the waist portion, the light transmittance of the knee portion, the weight of the slacks, and the weight of the outerwear. The air flow rate was measured based on JIS-L1096 (Frazier method), and the light transmittance was measured by the SM color computer method. The part where the air flow rate is measured is shown in FIG. 1-e, and the part where the light transmittance is measured is shown in FIG. 1-f. The measurement results are shown in Table 1 and FIGS.

As shown in Table 1 and FIG. 2, the slacks and suits of the present invention have a slacks and suit of the present invention more than that of the comparative product when compared with the currently coolest commercially available product measured as a comparative product. The suit has higher breathability and lower light transmission. Further, as shown in Table 1 and FIG. 3, the garment weight is about 20 in the slacks and the suit in the present invention only in the slacks as compared with the comparative product.
%, About 26% in jackets only, about 24 in suits
The result was as light as%. The high breathability and light weight mean that the heat generated by the body does not accumulate in the clothes and the burden on the body is small, so it can be worn in a cool and comfortable manner. Furthermore, since the functions of low light transmittance, that is, low transparency and high breathability are contradictory, it was almost impossible to combine these functions, but as shown in the table and graph, It was found that the slacks and the suit of the present invention can achieve both functions.

[0033]

[Table 1]

[0034]

As the slacks and suit of the present invention have the following functions at the same time, they are extremely cool and comfortable to wear.

1) It has extremely high air permeability, for example, it has 5 times or more air permeability as compared with summer clothes, which is conventionally said to be the coolest, depending on the site.

2) It is extremely lightweight, for example, in comparison with summer clothes, which are conventionally considered to be lightweight, the weight of a suit is 20% or more.

3) Since there is little see-through and the appearance is not unpleasant, the resistance is low and it is easily accepted even in the fields of conservative slacks and suits.

4) It is hard to lose its shape.

5) It has a smooth touch and does not cling to the body.

6) Even in formal wear that is apt to become hot in the past,
By using the slacks and suit of the present invention, the coolness can be improved, the cooling can be reduced, the energy can be saved, and it can greatly contribute to the world and humankind from the global environment and economical viewpoint.
