Description

The present invention relates to a fabric having a ventilation structure and outdoor products such as breathable clothing, tents, curtains and umbrellas using the fabric.
The fabric having a ventilation structure of the present invention can efficiently dissipate hot air and moisture accumulated inside, and rainwater does not enter the inside, so that it is particularly waterproof and has poor air permeability of the fabric itself. For example, various clothing such as rain clothes, various work clothes, Yakke, Anorak, windbreaker, trainer, poncho, mountaineering clothing, blouson, jumper, etc. It is preferably used for hoods and hoods in architecture.
In addition, the fabric having a ventilation structure of the present invention is used in a curtain, a camp, and a construction site used for setting up in an open air in order to efficiently dissipate the wind pressure received in a strong wind to the outside and attenuate the wind pressure. It is also used for curing screens, banners for advertisements, banners and banners, as well as hoods for umbrellas, parasols, and raincoats.

Conventionally, breathable clothes, particularly rain gowns worn in rainy weather, are required to have breathability and moisture permeability in addition to waterproofness. Recently, a waterproof and moisture-permeable fabric in which a fabric surface fabric is laminated on the surface of a waterproof and moisture-permeable film and a back fabric is laminated on the back surface has been proposed as a fabric used for rain clothes and the like. (Patent Document 1, Patent Document 2, etc.).

However, the waterproof and breathable fabric has a water-repellent surface on the surface due to long-term use and a water film is formed on the surface, or when wearing water-retaining underwear such as cotton fabric, the cotton fabric absorbs sweat. Acts as a water film when wet. Since the water film impairs moisture permeability, the inside of the wear is muggy. Moreover, since the water vapor | steam generate | occur | produced inside the wear does not permeate | transmit the waterproof moisture-permeable cloth unless the vapor pressure inside a wear rises from external pressure, the inside will be in a muddy state until the vapor pressure inside a wear rises. Furthermore, waterproof and moisture permeable wear is expensive because a fabric such as a woven fabric is laminated on both sides of the film in order to increase the strength of the waterproof and moisture permeable film. Wear made of waterproof / breathable fabric is unpleasant and uncomfortable with the sound from the fabric that occurs when swinging or in the wind in golf and other applications. There was a problem that a smooth swing could not be generated due to the occurrence or the upper garment clinging to the body. Also, in tents, especially camp tents etc., resident lives for a long time, and electronic devices such as personal computers and communication devices are installed for a long time. Therefore, it is required that air permeability and waterproofness are good.

As a result of thorough examination of the above-mentioned problem of the wear using the conventional waterproof or anhydrous permeable fabric, the present inventor is basically difficult to solve the above problem due to its moisture permeable mechanism. In particular, it was found that the above problem can be solved by providing an opening for ventilation in the wear and reliably preventing the intrusion of rainwater from the opening, and as a result of further investigation, a waterproof and moisture-permeable fabric and a moisture-impermeable property were found. The fabric is divided into upper and lower portions, the lower portion of the divided upper fabric and the upper portion of the lower fabric are overlapped, an overlapping portion is provided, and the upper end portion of the lower fabric is folded outward to form a dam for preventing rainwater intrusion, A first vent is provided between the upper fabric, a second vent is provided at the overlap of the upper fabric and the lower fabric, and the folded portion and the upper fabric are connected by a connecting means. Proposed connected breathable wear (Patent Document 3) .

The breathable apparel proposed by the present inventor uses a plane of a three-dimensional three-dimensional fabric as a flow path, so that the air flow rate is greatly increased, and water vapor generated inside the wear is discharged to the outside together with a large amount of air flowing into the wear. , The inside of the wear does not get steamed. Furthermore, by connecting the end portion of the upper fabric piece and the lower fabric piece of the overlapping portion with a thin fabric, it is possible to prevent the upper fabric piece from rolling up when the wind is strong.
The above proposal was an epoch-making proposal that solved the conflicting problems of steaming breathable clothing using conventional waterproof and moisture-permeable fabrics and preventing rainwater from entering. The first opening provided between the rainwater intrusion prevention weir and the upper cloth piece opened widely, and there was a risk that the breathable clothing would lose its shape. In addition, when the wearer leans forward, the first opening is pressed and closed, causing a part where the air flow decreases, and the wearer's body partially cools and places a burden on the body There was a problem.
An object of the present invention is to provide a breathable fabric with a ventilating function that has excellent breathability and has a portion where the amount of air flowing into the interior increases or decreases.
Another object of the present invention is to provide a breathable fabric with a ventration function that efficiently dissipates heat and moisture accumulated in the inside to the outside, and keeps the inside always in a comfortable state.

Accordingly, an object of the present invention is to improve the ventilation wear proposed in Patent Document 3, which is excellent in ventilation and has a ventration function with a small portion where the amount of air flowing into the interior increases or decreases. It is providing a property cloth.
Another object of the present invention is to provide breathable clothing and outdoor products using the breathable fabric.
Furthermore, the object of the present invention is to efficiently dissipate heat and moisture accumulated in the inside during hot periods, regardless of the environmental change of the season and place of use, and to prevent the internal heat from escaping to the outside during cold periods. To provide outdoor products.
An object of the present invention is to provide a rain hood, a curtain, an umbrella, and the like that efficiently dissipate the wind pressure received during a strong wind to the outside and attenuate the wind pressure.

Next, an embodiment of the breathable fabric of the present invention will be described with reference to the drawings. FIG. 1 is a schematic view of a breathable fabric 1 made up of two fabrics connected in the vertical direction. The lower portion of the upper fabric 2 and the upper portion of the lower fabric 3 are overlapped to form an overlapping portion 4. The upper end portion of the lower fabric 3 is folded outward to form a rainwater intrusion prevention weir 5, and the first opening 6 and the upper fabric are provided between the rainwater intrusion prevention weir 5 and the upper fabric. A second opening 7 is provided between the end of 2 and the lower fabric 3.
A first three-dimensional three-dimensional fabric 8 is disposed between the inside of the rainwater intrusion prevention weir 5 and the end portion of the upper fabric, and the end of the three-dimensional fabric 8 is attached to the rainwater intrusion prevention weir 5.
Reference numeral 16 denotes a sewing line. Reference numeral 11 denotes a sewing line. Further, a second three-dimensional fabric 9 is disposed between the end of the rainwater intrusion prevention weir 5 and the end of the upper fabric 2 and is integrated with the first three-dimensional fabric 8 in an overlapping manner. . An end portion of the second surface of the second three-dimensional solid knitted fabric integrated with the first three-dimensional solid knitted fabric and the upper fabric are sewn. Reference numeral 10 denotes a sewing line. A three-dimensional solid knitted fabric and an upper fabric at least 0.5 cm above the sewing line 10 are sewn. By deforming the second three-dimensional solid knitted fabric and the upper fabric in two places, shape loss is prevented. Reference numeral 12 denotes a sewing line. Reference numeral 13 denotes a fastener such as a snap in which the end portion of the upper fabric 2 and the lower fabric 3 below the overlapping portion 4 are spot-fixed at intervals of 5 to 10 cm, for example.

FIG. 2 is a schematic diagram of the back side of the breathable fabric, in which the top of the folded portion 5 of the lower fabric and the upper fabric are spot-fastened at the sewing portion 15. Although it may join with a fastener instead of sewing, it is necessary to consider that the fastener does not protrude inside the garment and give the wearer a sense of incongruity. In the case of an outdoor product, since a thick fabric is used, it is difficult to join it with sewing or a fastener. Therefore, it is preferable to connect the upper end portion of the lower fabric and the upper fabric with a connecting member such as a narrow fabric or a string-like body. The first opening 6 can be prevented from being greatly opened by spot-fastening or connecting the folded portion 5 of the lower fabric 3 and the upper fabric 2 with a connecting member. The interval for spot-fastening or connecting with a connecting member may be an interval that does not lose its shape and does not affect the air flow. A 10-15 cm spacing is usually appropriate for clothes. An interval of 20-30 cm is appropriate for outdoor products. In addition, it is preferable to attach the mesh fabric 14 to the inside of the garment because the first opening 6 cannot be seen from the outside.

When the breathable fabric 1 of the present invention is used for breathable clothing, it is preferable to provide the mesh fabric 14 on the entire inside of the breathable fabric 1 in order to prevent the wear and the underwear from sticking to each other. The mesh fabric 14 forms a gap between the underwear and the breathable wear, and prevents stickiness and the like with the underwear inside the wear. Moreover, when wearing a jacket, breathable wear can be smoothly worn without inserting fingers into the first and second openings 6 and 7 of the overlapping portion.
When using a breathable fabric for outdoor products, the mesh fabric need not be attached.

FIG. 3 is a detailed view of the overlapping portion 4, and the tip end portion of the lower fabric 3 is folded outward to form a V-shaped folded portion (rainwater intrusion prevention weir) 5. The length of the folded portion is suitably 0.5 to 5 cm, usually 1 to 3 cm. If it is less than 0.5 cm, raindrops stopped by the weir may pass through the weir and enter the first opening, and if it exceeds 5 cm, the folded portion forming the weir is deformed to form a raindrop passage. There is a risk. Further, the folding may be a single layer or multiple layers. In the case of a plurality of layers, it is necessary to sew the vicinity of a plurality of folds to be polymerized to integrate the V-shaped weir. In the case of multiple layers, even if the length of the folded portion is short, the entry of wind and rain can be reliably prevented. The overlapping portion between the lower part of the upper fabric 2 and the upper part of the lower fabric 3 is preferably 2 to 10 cm, and usually 2 to 5 cm. If it is less than 2 cm, it is difficult to produce the overlapping portion 4, and if it exceeds 10 cm, the air permeability may be lowered.

In FIG. 3 (1), the 1st three-dimensional three-dimensional fabric 8 is arrange | positioned between the inner side of the folding | turning part 5 and the edge part of an upper stage fabric. A commercially available three-dimensional solid knitted fabric can be used for the first three-dimensional solid fabric 8 and the second three-dimensional solid fabric 9 used in the present invention. The thickness of the commercially available three-dimensional solid knitted fabric is usually 3 to 15 mm. The first three-dimensional three-dimensional knitted fabric 8 of the present invention has its tip portion inserted inside the folded portion 5 so that the folded portion is always opened and the folded portion is prevented from adhering to the lower fabric. Therefore, the thickness of the first three-dimensional solid knitted fabric 8 is preferably as thin as possible. Usually, a thickness of 3 to 5 mm is appropriate.
Further, when the entire surface of the second three-dimensional solid knitted fabric 9 is joined to the upper fabric 2, the air flows into the wear from the cut surface of the second three-dimensional solid knitted fabric 9, so that a certain cross-sectional area (thickness) is present. is necessary. When a part of the second three-dimensional solid knitted fabric 9 is joined to the upper fabric 2, the three-dimensional solid knitted fabric usually has a thickness of 5 to 10 mm because of low air resistance. In that case, since air flows across the plane part of the second three-dimensional solid knitted fabric 9 and flows into the wear, the thickness may be small. Usually 3 to 8 mm is appropriate.

The front end portion of the first three-dimensional fabric 8 is inserted inside the folded portion 5 and joined to the folded portion. A second three-dimensional fabric 9 is disposed between the end portion of the folded portion 5 and the end portion of the upper fabric 2, and the first three-dimensional fabric 8 is superimposed and integrated. In addition, the upper fabric 2 is superimposed and superimposed on the other surface of the second three-dimensional solid fabric 9 superimposed and integrated with the first three-dimensional solid fabric 8, and the end of the second three-dimensional solid fabric is the upper step. It is joined and integrated with the fabric. The superimposed first three-dimensional three-dimensional fabric 8 and second three-dimensional three-dimensional fabric 9, or the second three-dimensional three-dimensional fabric 9 and the upper fabric 2 are integrated by, for example, adhesion, pressure bonding, sewing, or the like. Usually, sewing integration is appropriate for simplifying the process.
When the end of the second three-dimensional fabric 9 is projected from the end of the first three-dimensional fabric 8 and integrated, the projecting portion is fixed to or connected to the lower fabric 3 and the upper fabric 2 described later. It can be used as the attachment part of a member, and is preferable. Further, instead of superimposing and integrating two pieces of the three-dimensional solid fabric, a thin projecting portion that scrapes off the end surface of one thick three-dimensional solid fabric and inserts it inside the folded portion 5 may be provided.

FIG. 3 (2) is a detailed view of another example of the overlapping portion 4, in order to prevent the folded portion 5 at the tip of the lower fabric 3 from sticking to the lower fabric 3. A blocking prevention means 17 is provided on the front side. The blocking prevention means 17 may be provided on the inner side of the folded portion, and may be provided on either the inner side of the folded portion or the lower fabric facing the folded portion. As the blocking prevention means, a water-resistant resin sheet, a woven fabric or the like is used. In FIG. 3 (2), a thin three-dimensional fabric is attached. The width of the first three-dimensional three-dimensional fabric provided as the blocking prevention means 17 is usually 0.5 to 2 cm shorter than the length of the folded portion. A second three-dimensional fabric 9 is disposed from the end of the upper fabric 2 to the outside of the folded portion 5, and the end is joined to the folded portion 5. Reference numeral 16 denotes a sewing line.

FIG. 3 (3) is a detailed view of another example of the overlapping portion 4, in which a second three-dimensional three-dimensional fabric 9 is disposed between the end portion of the upper fabric 2 and the folded portion 5, and the tip portion thereof. Is inserted inside the folded portion 5. Therefore, the folded portion is always opened, and the folded portion is prevented from adhering to the lower fabric and closing. The front end portion and the folded portion 5 of the second three-dimensional three-dimensional fabric 9 and the other end portion of the second three-dimensional three-dimensional fabric 9 are integrated by sewing. In order to prevent the upper fabric from losing its shape, the lower end of the three-dimensional solid knitted fabric and the end fabric sewing line 10 of the upper fabric, and at least 0.5 cm, usually 0.8 to 1.5 mm above the sewing line 10 It is sewn in two places. Reference numeral 12 denotes an upper sewing line.

Further, as shown in FIG. 3 (4), when two superposed and three-dimensional three-dimensional fabrics 8 and 9 are wrapped with a mesh 18 made of water-resistant resin or the like, the fuzz of the cross section of the three-dimensional solid fabric is hidden. This is preferable because the connecting yarn can be prevented from falling off. Reference numeral 19 denotes a sewing portion in which two three-dimensional three-dimensional fabrics 8 and 9 are attached and integrated. It is preferable to wrap the second three-dimensional solid fabric shown in FIGS. 3 (2) and 3 (3) with a mesh. Since the air permeability is hindered when the mesh has a small opening ratio, it is preferable to select a mesh having an opening ratio that does not affect the air permeability.

FIG. 4 is an explanatory view for explaining a state in which air flows in the overlapping portion 4, and FIG. 4 (1) is a case where the entire surface of the second three-dimensional three-dimensional fabric 9 is joined and integrated with the upper fabric 2. 4 (2) shows a sewing line 10 at the lower end of the second three-dimensional three-dimensional fabric 9 and the tip of the upper fabric 2, and at least 0.5 mm from the sewing line, usually 0.8-1. This is an example in which the upper part of 5 mm is sewn. Reference numeral 12 denotes an upper sewing line. In FIG. 4 (1), the air which flowed in from the 2nd opening 7 flows into the wear inside from the 1st opening 6 through the edge part cross section of the 2nd three-dimensional three-dimensional fabric 9, as shown by the arrow. On the other hand, in FIG. 4 (2), the air flowing in from the second opening 7 passes through the end cross section of the second three-dimensional three-dimensional fabric 9 and the portion not joined to the upper fabric as indicated by the arrows. 6 flows into the wear. In this case, since the second opening 7 may be enlarged due to strong wind, the end portion of the upper fabric 2 and the lower fabric 3 below the overlapping portion 4 are connected to a connecting member such as a narrow fabric or string. By connecting at 20, the upper fabric 2 is prevented from rising. Instead of the connecting member, the ends of the lower fabric 3 and the upper fabric 2 can be spot-fastened with fasteners such as sewing, pins, buttons, and snaps.
The ends of the lower fabric 3 and the upper fabric 2 are connected or fixed at intervals of at least 5 to 10 cm. If the interval is too wide, the upper fabric 1 may be swelled by a strong wind, and if it is too narrow, the air permeability may be reduced.
The joining range between the second three-dimensional fabric 9 and the upper fabric 2 is appropriately determined depending on the outside air permeation performance and thickness of the three-dimensional fabric 9. In order to increase the circulation amount of the outside air, the three-dimensional three-dimensional fabric 9 is preferably as thick as possible in the case of FIG. 4 (1). On the other hand, in the case of FIG. 4 (2), it is preferable that the three-dimensional three-dimensional fabric 9 is thinner as the flow rate of outside air increases. Usually 3 to 8 mm is appropriate.

When the breathable fabric 1 of the present invention is used for breathable clothing, it is preferable to provide the mesh-like fabric 14 on the entire inside of the breathable fabric 1 in order to prevent adhesion between the wear and clothing. The mesh-like fabric 14 forms a gap between the garment and the breathable clothing, and prevents the clothing from sticking inside the garment. Further, when wearing the outerwear, the breathable wear can be worn smoothly without inserting fingers into the first and second vents 6 and 7 of the overlapping portion. When using a breathable fabric for outdoor products, the mesh fabric need not be attached.

The three-dimensional three-dimensional fabric used in the present invention is a three-dimensional knitted fabric composed of two layers of front and back knitted fabrics and connecting yarns connecting the two layers of knitted fabrics, and disclosed in JP-A-10-102363, JP 2000-138352 A, JP 02-74648 A, and the like.

The three-dimensional three-dimensional fabric 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. Non-water-absorbing 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 made of the same fiber as the two layers of the front and back layers, but usually a polyester fiber having an excellent compression recovery rate.
