Description

The present invention relates to a cloth and a garment having a ventilation structure whose functionality is improved by changing the structure of the cloth.

Since the fabric having the ventilation structure of the present invention can efficiently dissipate the hot air and moisture accumulated inside, work clothes, shirts, uniforms, jumpers, coats, casual wear, sports clothes, school clothes, Used for sportswear, lab coat, underwear and other clothing.
In particular, it is possible to improve the breathability of a cloth made of a fabric woven with a resin such as polyurethane or polyester, a waterproof cloth such as a resin sheet such as nylon or polyester, or a rubber sheet. It is suitably used for various waterproof clothes such as coats, rain suits, various work clothes, jackets, anoraks, windbreakers, trainers, ponchos, mountaineering clothes, and blousons.
In the following description, polyester fibers, polyvinyl alcohol fibers, natural fibers such as cotton and linen, textile products using regenerated fibers such as rayon, textile products such as knitted fabrics, resin coating on the fiber products, or resin films Sheet, laminated resin sheet such as nylon, polyester, polyethylene, polypropylene, etc., or laminated resin sheet, waterproof / breathable composite sheet with textiles treated with urethane coating, urethane laminate or acrylic coating, and rubber Sheets and the like are collectively referred to as fabrics.

Traditionally, clothes such as work clothes and shirts tend to sweat when they are hot, especially when wearing underwear such as shirts. When entering a building equipped with, body temperature suddenly drops and places a heavy burden on the body. Therefore, there is a demand for clothes with breathability and moisture permeability.
In particular, raincoats and rain suits that are worn in rainy weather have poor breathability, and the inside is steamed and sweating, causing discomfort, so it is strongly equipped with waterproof and breathable functions. It is requested.
In recent years, as a cloth for clothes having both waterproof and moisture permeable functions, a waterproof and moisture permeable cloth in which a waterproof and moisture permeable film is laminated on a cloth, and a woven fabric on the surface of the waterproof and moisture permeable film are laminated. A waterproof and moisture-permeable fabric having a back fabric laminated on its back surface has been proposed (see Patent Document 1, Patent Document 2, and Patent Document 3).

However, the conventional waterproof and moisture-permeable fabric has the following problems: (1) If a water film is formed on the surface of the fabric, the air holes are blocked and the moisture permeability is lowered. For example, clothes using waterproof and moisture-permeable fabrics may have a water film on the surface due to deterioration of the water repellency of the clothes surface due to long-term use, or when water-resistant underwear such as cotton fabric is worn In some cases, the cotton fabric sucks sweat and gets wet and acts as a water film, impairing moisture permeability.
(2) Since the waterproof and moisture-permeable cloth clothes cannot pass through the clothes until the water vapor generated inside the clothes rises to the external pressure or higher, the inside of the clothes is kept in a steamy state until the vapor pressure rises.
(3) If a fabric such as woven fabric or knitted fabric is laminated on the film in order to increase the strength of the water-permeable film, the manufacturing cost of the waterproof and moisture-permeable fabric is increased.
(4) A rain gown using a waterproof and moisture permeable fabric, for example, a rain gown for sports, is uncomfortable because the fabric does not have air permeability and the fabric is rubbed against each other when it is blown with wind. Especially in golf, smooth swinging is not possible due to the harsh sound at the time of swing and the top of the raincoat clinging to the body.

As a result of thorough examination of the conventional waterproof and moisture-proof fabric and the garment using the fabric, the present inventors have found that the fabric using the conventional waterproof and moisture-permeable fabric, particularly the rain garment, has no breathability. Therefore, it is basically difficult to solve the above-mentioned problems, and the conclusion that the air permeability is improved only by the fabric structure is reached, and the fabric is provided with a vent, and rainwater intrusion from the vent is prevented. (1) Breathability is improved, and the air flowing out from the vent is accompanied by moisture inside the clothes, so that stuffiness can be eliminated.
(2) The waterproofness of the rain garment is ensured by adopting a structure that reliably prevents rainwater from entering through the vents.
As a result of further investigation, the fabric was divided into upper and lower portions, the lower portion of the divided upper fabric and the upper portion of the lower fabric were overlapped, and the upper end portion of the lower fabric was folded outward to prevent rainwater intrusion prevention weirs. The folded piece and the end of the upper fabric are connected by a breathable connecting means such as a three-dimensional three-dimensional fabric, and the first vent is formed between the folded piece and the upper fabric. Proposed a breathable garment in which a second vent is provided between the end of the fabric and the lower fabric, and the lower fabric below the overlapping portion of the upper fabric is connected with a narrow fabric (patent) Reference 4).

A breathable garment having a vent hole proposed by the present inventors, such as a rain gown,
(1) Rainwater flowing in from the second vent is blocked by the rainwater intrusion prevention weir.
(2) The air flowing in from the second vent is discharged from the first vent to the outside along with the water vapor generated inside.
(3) By connecting the end fabric of the upper fabric and the lower fabric below the overlapping portion with a thin fabric, the end fabric of the upper fabric is prevented from rolling up when the wind is strong.
It was a revolutionary proposal for a rain gown that has breathability in addition to waterproof and damp proof due to the fabric structure, etc., but if the rain wearer bends forward or assembles both hands in front, the overlapping part provided on the back The upper fabric may be pulled laterally to block the first and second vents. When the vent is blocked, the air permeability and the moisture permeability are reduced. When the lower fabric is pulled, the lower fabric may hang down and lose its shape. Furthermore, the nonwoven fabric and three-dimensional solid knitted fabric used for the connecting means are thick and soft, so that it is difficult to sew with the upper fabric. There was a problem that wrinkles generated by shrinkage of the yarn appeared on the surface of the raincoat and the appearance was remarkably impaired.

Next, an example of a fabric having a ventilation structure of the present invention will be described with reference to the drawings. FIG. 1 is an explanatory view of a fabric 1 having a ventilation structure according to the present invention. The fabric 1 is provided with an overlapping portion 4 in which a lower portion of an upper fabric 2 and an upper portion of a lower fabric 3 are overlapped. A hydrophobic narrow three-dimensional three-dimensional knitted fabric 10 composed of a large number of connecting yarns 11 for connecting the upper knitted fabric 8 and the lower knitted fabric 9 to the overlapping portion 4, and an upper auxiliary fabric 13 joined to the upper knitted fabric 8. The ventilation member unit 5 composed of the lower auxiliary fabric 14 joined to the lower surface knitted fabric 9 is attached. A is a first vent formed between the upper end of the lower auxiliary fabric and the upper fabric 2, and B is a second vent formed between the lower end of the upper fabric 2 and the lower fabric 3. The mouth.
As shown in FIG. 2A, the ventilation member unit 5 has an upper auxiliary fabric 13 bonded to an upper surface knitted fabric 8 of a three-dimensional solid knitted fabric through an adhesive layer 12. A lower auxiliary fabric 14 is bonded to the lower surface knitted fabric 9 of the three-dimensional solid knitted fabric 10 via an adhesive layer 12.
The upper and lower auxiliary fabrics 13 and 14 of the ventilation member unit 5 are wider than the three-dimensional three-dimensional knitted fabric 10, and have, for example, joint portions 15 of about 5 to 20 mm, usually about 8 to 15 mm, at both ends thereof. Further, when the fabric 1 having a ventilation structure of the present invention is applied to a rain garment or the like, when the ventilation member unit 5 is joined to the upper and lower fabrics 2 and 3, a gap is formed at both left and right end portions, and rainwater enters the interior from the gap. There is a risk of intrusion. Generation | occurrence | production of this space | gap can be prevented by the following method, for example. As shown in FIG. 2B, when the ventilation member unit 5 is manufactured, (1) the thickness of the left and right side portions of the three-dimensional solid knitted fabric 10 is gradually reduced and sandwiched between the upper and lower fabrics 13 and 14. Join. (2) The left and right ends 6 of the three-dimensional solid knitted fabric 10 are joined in a compressed state. FIG. 2B shows the method of (2), in which sewing is performed near the left side of the upper and lower fabrics. An alternate long and short dash line is a sewing line 7, which indicates two sewing lines.

An upper end portion of the upper auxiliary fabric 13 is sewn to the upper fabric 2, and further, a sealing tape (see FIG. 5) is provided from above the sewing line on the back side of the upper auxiliary fabric 13 in order to prevent rainwater from penetrating from the sewing line. (Not shown) is attached. Instead of sewing, the upper end of the upper auxiliary fabric 13 is attached to the back surface of the upper fabric 2,
Or you may join with an adhesive tape.
The lower end portion of the upper stage auxiliary fabric 13 is joined, for example, sewn to the tip end portion of the folded piece 17 that is the inner lower end portion of the upper stage fabric 2 folded shortly. You may join by double-sided adhesive tape, welding, adhesion, etc. instead of sewing. Since the overlapping portion 4 has a double structure of the upper fabric 2 and the upper auxiliary fabric 13, wrinkles and irregularities of the upper auxiliary fabric 13 appearing on the attaching portion of the three-dimensional solid knitted fabric may appear on the surface of the upper fabric 2. There is no loss of appearance.

The tip of the lower fabric 14 or the lower auxiliary fabric 14 is preferably subjected to bead processing (piping) 16 as shown in FIG.
The edge processing (piping) 16 is performed so as to wrap a core material such as a bias cloth, a tape, a ribbon, a twisted thread, and a cord at the tip of the lower fabric 14 or the lower auxiliary fabric 14. An edge-treated tape, such as a piping tape, may be attached to the upper end of the lower fabric 3 or the lower auxiliary fabric 14. Since the front end of the fabric has been subjected to a beading process, the front end portion becomes hard, and even if the lower fabric 3 is pulled downward, it does not lose its shape. In the case of a soft fabric, the bead processing 16 may hit the wearer's back, resulting in poor comfort. In that case, it is preferable to use a soft core material such as a thread core for the core material of the edge. When using a rigid fabric or rubber sheet that does not lose its shape, it is not necessary to perform the edge processing.

A method of joining the upper auxiliary fabric 13 or the lower auxiliary fabric 14 to the upper surface knitted fabric 8 or the lower surface knitted fabric 9 of the three-dimensional solid knitted fabric constituting the ventilation member unit 5 via the adhesive layer 12 is not particularly limited. A joining method is adopted.
(1) The upper and lower auxiliary fabrics on the upper and lower surfaces of the hydrophobic belt-like three-dimensional three-dimensional knitted fabric 10 composed of a large number of connecting yarns 11 that connect the upper knitted fabric 8 and the lower knitted fabric 9 with an adhesive layer 12 made of an adhesive. In the case of joining, an adhesive is applied to the upper auxiliary fabric 13 and the lower auxiliary fabric 14 to provide an adhesive layer 12, and then a strip-shaped three-dimensional solid knitted fabric 10 is laminated on the adhesive layer 12 of the upper auxiliary fabric 13. Then, the lower auxiliary fabric 14 having the adhesive layer 12 is laminated on the three-dimensional solid knitted fabric 10. Then, it can laminate | stack and integrate by interposing between the shaping | molding die of a hot press machine, and heating and pressurizing. Further, after laminating the upper and lower auxiliary fabrics and the three-dimensional solid knitted fabric 10 via the adhesive layer 12, the laminated body is heated, and then laminated between the forming dies of a cold press machine and pressurized. It can also be integrated. Moreover, when using an adhesive resin film, it can also laminate | stack by laminating | stacking by interposing a film between the upper-lower fabric and the strip | belt-shaped three-dimensional solid knitted fabric 10, and heating and pressurizing it after that, and can also be integrated.
The adhesive that joins the upper and lower fabrics and the three-dimensional solid knitted fabric is not particularly limited, and various adhesives can be used. Examples of the adhesive include an emulsion having an adhesive component, a slurry, a gel adhesive, a powder adhesive, an adhesive resin film, and an adhesive made of a foamed resin.

(2) Fabrics such as a fabric in which a fiber woven fabric is coated with a resin such as polyurethane, polyester, or acrylic, or a thermoplastic sheet such as vinyl chloride can be welded by heating the fabric until it exceeds the melting point and applying pressure. . Welding techniques include technologies such as sonic welding, vibration welding, induction welding, high frequency welding, semiconductor laser welding, and thermal welding, among which high frequency welding is performed in a short time because only the welding location is internally heated. The finish is beautiful and preferable because it does not affect the part that is not welded. In the high-frequency welding, a metal mold serving as an electrode is pressure-bonded to a laminate composed of the lower auxiliary fabric 14, the three-dimensional three-dimensional knitted fabric 10, and the upper auxiliary fabric 13, and the metal mold is pressure-bonded by electromagnetic waves output from the high-frequency vibration tube. By inductively heating only the portion, an adhesive layer in which the surfaces of the upper and lower auxiliary fabrics 13 and 14 are melted can be formed and welded to the three-dimensional solid knitted fabric 10.

The upper knitted fabric 8 and the lower knitted fabric 9 of the three-dimensional solid knitted fabric 10 are joined to the surface of the upper and lower fabrics 14. However, the surface treatment agent coated on the surface of the upper and lower fabrics 14 may reduce the bonding strength with the upper and lower fabrics 3. In that case, (1) the surface treatment agent coated on the surface of the upper and lower fabrics 14 is removed with a solvent or the like, or (2) the back surface of the upper and lower fabrics 14 is used as a joint surface with the three-dimensional solid knitted fabric 10. As a result, a decrease in bonding strength can be prevented. For example, when (2) is adopted, the back surface of the lower auxiliary fabric 14 is joined to the bottom knitted fabric 9 of the three-dimensional solid knitted fabric 10 as shown in FIG. In that case, a hanging part having a length corresponding to a joint part with the upper part of the lower fabric is provided at the lower end of the lower auxiliary fabric 14. The upper portion of the lower auxiliary fabric 14 is folded downward at the upper end portion of the three-dimensional solid knitted fabric and subjected to bead processing (piping). The upper end portion of the lower fabric 3 is joined to the hanging portion of the lower auxiliary fabric 14. The term “joining” as used in the present invention is a general term for adhesion, adhesive tape, sewing, welding, and the like.

The three-dimensional three-dimensional knitted fabric 10 has a small ventilation resistance and has a thickness of 5 to 15 mm, preferably 8 to 10 mm, and a width of 10 to 40 mm, preferably 15 to 25 mm in order to prevent raindrop transmission. A solid knitted fabric is used. When the thickness is 5 mm or less, the ventilation cross-sectional area is small. Moreover, it is desirable that the cross-sectional area (thickness) is large, but if the thickness is 15 mm or more, it is difficult to handle, and a large fault is formed on the fabric, so that the appearance is poor. If the width of the three-dimensional solid knitted fabric 10 is 10 mm or less, it is difficult to cut the three-dimensional fabric. If the width is 40 mm or more, the air permeability is lowered, which is not practical. The thickness and width of the three-dimensional solid knitted fabric are determined in consideration of comfort and design, especially in clothes.

The three-dimensional solid knitted fabric 10 has a structure in which two layers of knitted fabrics are connected with connecting yarns, and is usually knitted by a double raschel knitting machine, a double tricot knitting machine, a double circular knitting machine, a flat knitting machine having a V bed, or the like. The Hydrophobic fibers such as polyester fibers, polyethylene fibers, polypropylene fibers, polyvinyl chloride fibers, and polyvinylidene chloride fibers are used as the yarns constituting the two layers of the front and back layers. The connecting yarn for connecting the two layers of the front and back layers is the same fiber as the two layers of the front and back layers, but usually a polyester fiber having an excellent compression recovery rate is preferably used.

In FIG. 4, the upper and lower end portions of the upper stage auxiliary fabric 13 are sewn to a folded piece 17 that is a long turn of the lower end portion of the upper stage fabric 2 inside. In addition, the upper end of the folded piece is joined to the upper fabric with a sealing tape. The joining of the lower auxiliary fabric 14 and the lower fabric 3 is the same as in FIG.
FIG. 5 shows another example of a fabric having a ventilation concept. The upper end of the lower fabric 3 is sewn to the upper end of the lower auxiliary fabric 14, and the lower end of the lower auxiliary fabric 14 is also sewn to the lower fabric 3. Has been. The joining of the upper auxiliary fabric 13 and the upper fabric 2 is the same as in FIG.

FIG. 6 is an example of joining the upper fabric 2 and the upper auxiliary fabric 13 of the fabric having the ventilation concept. The front end portion of the folded piece 17 and the lower end portion of the upper auxiliary fabric 13 in which the lower end portion of the upper fabric 2 is folded back inward. Are joined. The upper end portion of the upper stage auxiliary fabric 13 is sewn to the upper stage fabric 2 with the folded piece 17 interposed therebetween. A sealing tape is attached to the back side of the sewing line. The joining of the lower auxiliary fabric 14 and the lower fabric 3 is the same as in FIG.

FIG. 7 shows another example of joining the upper auxiliary fabric 13 and the upper fabric 2 having a ventilation concept. A mesh fabric 19 is attached between the lower auxiliary fabric 14 and the lower auxiliary fabric 13. The mesh fabric 19 can conceal the exposure of a large number of connecting yarns 11 of the three-dimensional solid knitted fabric 10 from the ventilation member unit. In order to prevent the three-dimensional solid knitted fabric 10 from being deteriorated by ultraviolet rays, the mesh fabric 19 is preferably a dark black fabric such as black or amber, which hardly transmits ultraviolet rays. When the color is not a dark black color, it is preferable that the ventilation member unit 5 is inconspicuous, for example, a color similar to the upper and lower fabrics. The joining of the upper auxiliary fabric 13 and the upper fabric 2 and the joining of the lower auxiliary fabric 14 and the lower fabric 3 are the same as in FIG.

Next, an example of a manufacturing method of the ventilation member unit 5 used for the fabric 1 having the ventilation structure shown in FIG. 7 will be described with reference to FIG. FIG. 8 shows an example in which a mesh fabric is attached by sewing. In addition to sewing, the mesh fabric may be attached by bonding means such as adhesion, adhesive tape, or welding. The mesh fabric is preferably attached when the connecting yarn of the three-dimensional solid knitted fabric 10 is visible from the outside. However, in a thin three-dimensional solid knitted fabric having a thickness of 8 mm or less, the connecting yarn of the three-dimensional solid knitted fabric 10 is difficult to see from the outside. The mesh fabric may not be attached. The manufacturing method of the ventilation member unit 5 is as follows.
(1) The upper and lower tier auxiliary fabrics 13 and 14 are folded leaving the end corresponding to the stitched portion with the upper and lower tier fabrics 2 and 3, and the bent portions are opposed to each other to correspond to the thickness of the three-dimensional solid knitted fabric 10. Place with a gap.
(2) Next, the mesh fabric 19 is arranged on the upper part so as to straddle the gap, and both ends of the mesh fabric 19 are joined to the upper and lower auxiliary fabrics 13 and 14.
(3) The three-dimensional solid knitted fabric 10 is laminated and adhered to the lower auxiliary fabric 14 provided with the adhesive layer 12. after that,
(4) The upper auxiliary fabric 13 provided with the adhesive layer 12 is folded and laminated with the three-dimensional three-dimensional knitted fabric 10 and attached. If necessary, the laminate can be completely adhered by heating and then interposing between the molds of a cold press and pressurizing. The upper end of the lower auxiliary fabric 14 is piped.

FIG. 9 is a detailed view of the overlapping portion 4 in which the second ventilation hole B of the fabric 1 having a ventilation structure can be opened and closed by the slide fastener 20 or the opening width can be adjusted, and has the ventilation structure shown in FIG. A pair of support tapes 20 (1) and 20 (2) of a slide fastener are attached to the lower end of the upper auxiliary fabric 13 and the lower end of the lower auxiliary fabric 14 constituting the fabric 1. The support tapes 20 (1) and 20 (2) are preferably attached downward so that raindrops flowing from the second vent B do not collect at the joint between the support tape and the fabric. Moreover, it is preferable to install one slider (not shown) or one at each end, since the opening position and the opening width of the second vent B can be adjusted. By opening and closing the second vent B or adjusting the opening width, the amount of air flowing into or out of the inside can be adjusted, and an effect such as prevention of hypothermia in winter mountain climbing or the like is expected.

FIG. 10 is an example in which a ventilation member unit is attached to clothes such as a ready-made rain gown without a ventilation structure to change to a clothes having a ventilation structure.
(1) After cutting the ventilation member unit attachment position of clothes into a straight line with a cutter or the like and dividing the fabric into upper and lower fabrics 2, 3,
(2) The ventilation member unit 1 is inserted from the cut portion, and the lower end of the upper auxiliary fabric 13 is joined to the lower end portion of the upper fabric 2. The upper end of the upper auxiliary fabric 13 is also joined to the back surface of the upper fabric 2 with a sealing tape 18 or the like.
(3) The lower auxiliary fabric 14 has its lower end made longer than the position of the lower end (cut) of the upper fabric 2 by the length of the joint, and the upper end of the lower fabric 3 is joined to the lower end of the lower auxiliary fabric 14. To do. For joining, sewing, welding, adhesion, etc. are adopted, but if a double-sided adhesive tape is adopted, it can be joined easily and cleanly. In the case of a double-sided adhesive tape, strong adhesion is possible by removing the surface layer of the adhesion surface before adhesion.
(4) In the rain garment, as shown in FIG. 2, the upper and lower fabrics 2 and 3 stacked on the upper and lower sides of the ventilation member unit 1 are sewn in the vertical direction by compressing both end portions of the ventilation member unit 1. In addition, it is preferable to use the same fabric as the fabric used for clothes for the upper and lower stage auxiliary fabrics 13 and 14. The upper and lower fabrics 2 and 3 are sewn in the vertical direction by compressing both end portions of the ventilation member unit 1. In addition, it is preferable to use the same fabric as the fabric used for clothes for the upper and lower stage auxiliary fabrics 13 and 14. This process is not necessary for clothes other than rain clothes.
When the ventilation member unit 5 is attached by the above method, a ready-made garment having no air permeability can be easily changed to a garment having a ventilation structure.

FIG. 11 is a schematic diagram of a rain gown using the fabric 1 having the ventilation structure of FIG. 1. The rain knob W flows down along the upper and lower fabrics 2 and 3, and the outside air including the rain knob is shown as an arrow X. From the two openings B, a large number of connecting yarns 11 constituting the three-dimensional three-dimensional knitted fabric 10 enter the inside from the vertical direction. However, raindrops are captured by the many connecting yarns 11 and are prevented from entering the inside of the rain garment. The outside air passes between the connecting yarns of the three-dimensional solid knitted fabric 10 and enters the rain gown. The outside air flowing into the rain garment is discharged from the first opening A through the three-dimensional solid knitted fabric 10 to the outside through the second opening B as indicated by an arrow Y while accompanying warm and humid air in the rain garment. Fine raindrops flowing from the second opening B adhere to the hydrophobic connecting thread 11 constituting the three-dimensional solid knitted fabric 10, and further, the fine raindrops gather by repeating the phenomenon of fine raindrops adhering thereto. Then, it grows gradually and finally flows out as a collection of large raindrops (for example, 20 to 100 μm in diameter). In addition, since the upper and lower auxiliary fabrics 13 and 14 are in close contact with and joined to the entire surface of the three-dimensional solid knitted fabric 10, the second opening B of raindrops that diffuses in the form of a water film when the water repellency of the fabric decreases.

Example 1
In order to confirm the effect of rain kappa using the fabric having the ventilation structure of the present invention, the temperature in the rain gown and the outside air temperature during walking on the treadmill at a speed of 90 m / min were measured under the following three conditions, and the temperature difference between the outside air and the rain gown: Asked.
-Start running under windless conditions with the second opening of the raincoat closed with tape, peel off the tape after 40 minutes to open the opening, and walk for 20 minutes in that state.
-It is the same as the above-mentioned condition, but after walking for 20 minutes, air is blown (low wind) by an industrial fan from 2 m ahead of the subject.
-With the second opening of the rain gown open, walk for 60 minutes while blowing air (low wind) with an industrial fan from the front of the subject 2 m.
In addition, the rain cap used in the experiment produced a kappa of FIG. 12 using a cloth having a water pressure resistance of 2000 mm or more and moisture permeability: 0 coated with nylon and urethane. The ventilation structure of FIG. 1 was employ | adopted for the fabric. In addition, a ventilation member was used which accommodated a three-dimensional solid knitted fabric (“Forge R” manufactured by Asahi Kasei Corporation, product number: AKE65710 (thickness: 10 mm)) cut into a width of 20 mm in an accommodation space made of polyester mesh fabric. Polyester mesh fabric was used for the lining.
A J thermocouple was used to measure the temperature. The J thermocouple was attached to the surface of the garment with double-sided adhesive tape so that the J thermocouple would not touch the garment or kappa, and the kappa was worn over it.
The subject wore a long T-shirt made of the same material on a polyester short-sleeved T-shirt.
FIG. 29 is a graph showing changes in the difference between the outside air temperature and the kappa temperature by measuring the outside air temperature and the kappa temperature during walking on the treadmill under the above three conditions. When the second opening is closed with tape before starting walking from the graph, and the tape is peeled off after 40 minutes to open the opening, the outside air and the temperature in the kappa have decreased, so the ventilation structure of the present invention is effective. It is clear.

Example 2 and Comparative Example 1
Next, in order to compare the effects of the kappa 1 using the fabric having the ventilation structure of the present invention (the kappa used in Example 1) and the kappa 2 and 3 using the two types of fabrics having different functions, each kappa is subjected to each subject. Wearing a treadmill, walking for 60 minutes (speed 90m / min) while blowing with an industrial fan (weak wind) from the front 2m, outside temperature, kappa temperature, heart rate, oxygen intake during walking on the treadmill The amount was measured.
Kappa 1: Invention
Fabric: Nylon coated with urethane
Water pressure resistance: 20000 mm or more
Moisture permeability: 0
Kappa 2: Made by North Face
Product Name: North Face NP10180
Fabric: “HYVENTR ・ D” (Nylon coated with waterproof breathable urethane
Ting)
Water pressure resistance: 20000 mm or more
Moisture permeability: 15000 g / m2 / 24h or more Kappa 3: Mac
Product Name: Phoenix AS-7200
Fabric: Nylon coated with moisture permeable urethane
Water pressure resistance: 10,000mm or more
Moisture permeability: 2000g / m2 / 24h or more

FIG. 30 is a graph showing changes in the outside air temperature and the in-kappa temperature difference during walking on the treadmill when each kappa is worn. Each kappa showed a steady state 10 minutes after the start of walking, but kappa 3 became steady when the kappa temperature was about 2.2 ° C. higher than the outside temperature, and both kappa 1 and kappa 2 were about 1 outside the outside temperature. It became steady at a high temperature of 9 ° C.
Therefore, the kappa 3 has a higher kappa temperature than the kappa 1 and 2, and the kappa 1 and the kappa 2 have the same kappa temperature, in other words, a kappa using the cloth having the ventilation structure of the present invention, The moisture permeation performance of the kappa using the fabric with excellent wettability is equivalent.

FIG. 31 is a graph showing changes in the heart rate of a subject during walking on a treadmill when wearing each kappa. From the figure, it is clear that when walking with the kappa 1, the heart rate is lower than when walking with the kappa 2, 3.
Since the heart rate shows a high value when working or exercising in a high temperature environment, the walking speed during walking on the treadmill when wearing each kappa is the same speed (90 m / min), so a low heart rate means kappa 1 Indicates that the burden on the living body is less than that of kappa 2 and 3.

FIG. 32 is a graph showing changes in the amount of oxygen intake of a subject during treadmill walking when wearing each kappa. Oxygen intake is proportional to energy consumption during work and exercise, and increases in high-temperature environments.
From the graph, when walking with the kappa 1, the oxygen uptake is clearly lower than when walking with the kappa 2,3.

FIG. 33 is a graph showing changes in the oxygen pulse calculated from the heart rate and oxygen intake of the subject who is walking on the treadmill when wearing each kappa. The oxygen pulse is a value indicating the amount of oxygen supplied per kg of body weight when the heart contracts for one beat, and when the oxygen pulse is a high value, it is an index indicating that the heart is working efficiently. It is shown from the graph that when walking with the kappa 1 wearing, the oxygen pulse is clearly higher than when walking with the kappa 2, 3.

From the above graphs, the kappa 1 using the fabric of the present invention having a ventilation structure is equivalent to the kappa 2 using a fabric having excellent moisture permeability, but the kappa using a fabric having no moisture permeability is used. It was better than 3.
On the other hand, regarding the load on the living body, the kappa 1 using the fabric of the present invention is less burdensome than the kappa 2 and 3 and has less fatigue.

The above examples and comparative examples are performed indoors instead of in the rain, but the outdoor temperature is low in the rain, and the temperature in the kappa increases due to heat generated by the body, so there is a possibility that the moisture permeability can be further improved. is there.
Also, in rainy weather, wind pressure is received during walking, and the amount of ventilation increases, which may improve the kappa performance.
Furthermore, the excellent function of the fabric having the ventilation structure of the present invention can be applied to clothes such as jumpers and uniforms worn in fine weather, outdoor products such as tents, and the like.

Example 3
The presence or absence of rainwater intrusion from the first opening of the kappa 1 using the fabric having the ventilation structure used in Example 1 under strong wind was tested. First, a tissue paper for confirming the invasion of rainwater was pasted around a first opening provided in the kappa, and then a subject wearing a polyester sports shirt on a cotton underwear was allowed to wear the kappa. The air was blown (strong) with an industrial fan, and water was dripped into the blower opening to create a severe wind and rain state. Next, the subject exercised for 10 minutes 2 meters ahead of the industrial fan. Thereafter, it was visually confirmed whether or not the tissue paper attached to the first opening was wet, but no wetness could be confirmed.

The cloth having the ventilation structure of the present invention is not deformed and has excellent breathability, and since the opening is not compressed and closed, work clothes that can efficiently dissipate accumulated heat and moisture to the outside.
