Description

  The present invention relates to a fabric excellent in a feeling of cooling at the time of wearing exercise used for various clothes such as sportswear, mountaineering clothes, and work clothes.

  Conventionally, many examinations have been made to obtain a comfortable wearing feeling in fabrics worn during exercise such as sports. In particular, in sports and outdoor fields where exercise is high, there is a strong demand for suppressing an increase in fever from the body during or after exercise. In particular, during the summer exercise, the demand for improving the heat is very strong, and many studies have been made heretofore. In general, by using hydrophilic fibers with excellent hygroscopicity and water absorption, it is possible to promote sweat treatment and obtain a cooling effect, or by using a fabric composed of fibers with high thermal conductivity A method of obtaining a feeling of cool contact (cool feeling) has been adopted.

In order to improve these methods and obtain an effect more efficiently, for example, a method of obtaining a cooling effect by promoting water absorption and quick drying of the fabric using a modified cross-section polyester containing titanium oxide (for example, patents) Proposes a method (see, for example, Patent Document 2) that combines a highly heat-conductive filament yarn and hydrophilic fiber to promote a feeling of cold contact during wearing and to provide comfort through cooling. Has been.
JP 2005-179810 A JP 2003-293244 A

However, when obtaining a water-absorbing speed sensation effect using a modified cross-section yarn made of a hydrophobic polymer such as polyester as in Patent Document 1, the effect can be obtained only after a certain degree of sweating occurs. In addition, when sweating intensely, sweat treatment cannot catch up and a sufficient cooling effect cannot be obtained.
On the other hand, in the case of using a material with high thermal conductivity as in Patent Document 2 to promote a feeling of cool contact, a slight effect can be obtained in the initial stage of wearing, but a continuous effect cannot be obtained. Furthermore, when continuous exercise was performed continuously, these effects were hardly seen.

  An object of the present invention is to solve the above-mentioned conventional problems and to provide a fabric excellent in cooling feeling during wearing exercise used for various clothes such as sportswear, mountaineering clothes, and work clothes.

The fabric excellent in the cooling feeling at the time of wearing exercise of the present invention which can solve the above-mentioned problems has the following configuration.
(1) A fabric composed of a mesh hole portion and a ground portion made of a knitted fabric, and the average area per mesh hole portion is not less than 0.25 mm ^{2 and not} more than 30 mm ² , and the mesh hole portion with respect to the entire fabric The area ratio is 3% or more and 70% or less, the air permeability of the fabric is 100 cc / cm ² · s or more, and the skin surface temperature change (ΔTW) in the exercise evaluation with the fabric is not worn A fabric excellent in cooling feeling during wearing exercise, characterized by being larger than skin surface temperature change (ΔTS) in exercise evaluation.

  (2) A synthetic fiber having a flat cross section is used for part or all of the knitted fabric of the ground portion, and the maximum diameter a (long axis) of the flat cross section and the maximum diameter length b (short axis) perpendicular to the long axis ), The flatness a / b is 2 or more, and the fabric is excellent in cooling feeling during wearing exercise according to (1).

  (3) The ground part is water-absorbing processed with a water-absorbing agent, the value of the water-absorption rate dropping method conforming to JIS-L-1907 is 3 seconds or less, and the diffusive residual moisture content is less than 10% after 50 minutes. The fabric excellent in the cooling feeling at the time of wearing exercise as described in (1) or (2) characterized by the above-mentioned.

  The fabric of the present invention in which a mesh hole portion of a specific size is present in a specific area ratio has a skin hose effect due to the hose effect of airflow that passes through the mesh hole portion during wearing movement (water is generated vigorously when the hose is squeezed). The surface temperature is changed efficiently. As a result, the cooling feeling is continuously maintained during continuous motion. Therefore, it is very useful as a material for various clothes such as sportswear, mountaineering clothes, work clothes, and the like worn during actions involving continuous exercise.

The present invention will be specifically described below.
The fabric used in the present invention may be woven or knit such as circular knitting or warp knitting. In the case of a woven fabric, it is possible to make a fabric that is thin and light, yet has excellent strength and wear. In the case of knit, it is possible to make a fabric having extensibility and soft texture.

  The fabric used in the present invention includes a mesh hole portion and a ground portion made of a knitted fabric. The material of the knitted fabric may be synthetic fiber or natural fiber. From the viewpoint of the hose effect of the airflow passing through the mesh hole portion, a fabric mainly composed of a synthetic fiber and having no airflow suppression by fluff is preferred. Synthetic fibers include polyester fibers such as polyethylene terephthalate, polytrimethylene terephthalate and polybutylene terephthalate, polyamide fibers such as nylon 6 and nylon 66, polyolefin fibers such as acrylic fiber, polypropylene and polyethylene, polyurethane fibers and polyimide fibers. Illustrated. These synthetic fibers are used alone or in combination to produce a knitted fabric. As the synthetic fiber, either a monofilament or a multifilament is used from the viewpoint of imparting a function.

(Function)
The following can be considered as a mechanism for the fabric of the present invention to promote a cooling sensation during wearing exercise.
It is generally known that on the skin surface, there are a thermoreceptor and a cold receptor as organs for feeling temperature (hot and cold). The activity of these receptors (the intensity of receptor activity becomes warm and cool) is (1) static activity determined by absolute temperature, and (2) temperature. It can be roughly divided into dynamic activity that depends on changes. The magnitude of this dynamic activity increases as the rate of temperature change increases and the change temperature increases. That is, by quickly and greatly increasing the temperature change of the skin surface, a strong cold feeling can be felt. A cooling material using these phenomena is the fabric of the present invention.

  On the other hand, an air layer existing between a person's skin and clothes has a free air layer that becomes warm due to the effect of body temperature and that is relatively mobile due to a stationary air layer that stays on the surface of the skin and flapping of clothes.

  The product of the present invention efficiently moves this static air layer by utilizing the movement during exercise and generating a strong air flow to the skin surface, resulting in a temperature change of the skin surface and promoting a cooling feeling. Is.

In order to cause these phenomena, a mesh hole portion is provided in the fabric in order to generate a strong airflow to the skin surface.
A mesh hole is a hole that is partially made in the fabric and serves as a path for airflow. There are several ways to make a hole, such as a method using a weaving and knitting organization such as Shikako, mesh organization, power net organization, tulle organization, leash weaving, a method of making holes in the fabric using punching or laser cutting, and opal processing. Although the method of making a hole etc. can be considered, any method may be used.

  In order to obtain wearing comfort with such an effect, the change in skin surface temperature (ΔTW) in the exercise evaluation wearing the fabric is larger than the change in skin surface temperature (ΔTS) in the exercise evaluation when not worn. It is important to. The temperature change on the skin surface can be confirmed by a test using a temperature sensor.

  In order to generate a strong air flow to the skin surface and move the static air layer efficiently, the area of the mesh hole and the area occupied by the entire fabric are important. If the area of the mesh hole portion is too small, the amount of gas as a fluid passing through the mesh hole is reduced, and a strong airflow cannot be obtained. On the other hand, even when the area of the mesh hole portion is too large, the velocity of the gas passing through the mesh hole does not increase and a strong air current cannot be obtained.

Considering these matters, the average area per mesh hole portion is preferably 0.25 mm ² or more and 30 mm ² or less, and more preferably 0.30 mm ² or more and 15 mm ² or less. Further, the average area per one mesh hole portion upper limit, if you want to prevent sheer fabric, depending on the application and intended use, for ^{example, 10mm 2, 5mm 2, 3mm} 2, and 1.5 mm ² Select as appropriate. However, in order to reduce the average area per mesh hole portion, it is important to design the area ratio of the mesh hole portion in the entire fabric to be higher within the range of 3 to 70%.

  The area ratio of the mesh hole portion in the entire fabric is also important for the same reason as that for the average area of the mesh hole portion, and is 3% or more and 70% or less. More preferably, it is 4% or more and 50% or less. As described above, when the average area per mesh hole portion is reduced, it is preferable to design so that the area ratio of the mesh hole portion in the entire fabric is increased.

These fabrics must be highly breathable to obtain airflow. In the present invention, the size and ratio of the mesh holes are controlled so that the air permeability of the fabric is 100 cc / cm ² · s or more. The air permeability of the dough is preferably 150 cc / cm ² · s or more, more preferably 200 cc / cm ² · s or more, and particularly preferably 300 cc / cm ² · s or more.

  The portion (ground portion) other than the mesh hole portion of these fabrics preferably has a low air permeability in order to increase the speed of gas passing through the mesh hole portion. In order to obtain these structures, it is effective to use a synthetic fiber having a flat cross-sectional shape. By using a synthetic fiber having a flat cross section, the fibers overlap each other, and the effect of reducing the air permeability is improved. That is, an air blocking effect is obtained. The flatness of the synthetic fiber is preferably 2 or more.

  The flatness b / a is a ratio of the maximum diameter a (long axis) of the flat cross section to the maximum diameter length b (short axis) orthogonal to the long axis. That is, when the cross-sectional shape of a single yarn is approximated to an ellipse, the major axis a can be defined by the width of the single yarn, and the minor axis b can be defined by the thickness of the single yarn. Further, the cross section of the yarn does not need to be strictly an ellipse, and may have protrusions or depressions in part within a range that does not affect the overall flatness. In such a case, the flatness may be calculated by approximating an ellipse that does not impair the overall outer shape. The flatness calculated in the present invention is a numerical value expressed as an integer by rounding off the first decimal place.

  Similarly, as another method for lowering the air permeability of a portion other than the mesh hole portion (ground portion), a method of performing a calendering process on the synthetic fiber can be given. By performing a calendering process on the synthetic fiber, the synthetic fiber having a round cross section can be made flat. Further, the flatness can be further increased by using a calendering treatment in combination with a synthetic fiber having a flat cross-sectional shape.

  The ground portion (knitted fabric) of the fabric of the present invention is subjected to water absorption processing. By performing water-absorbing processing on the ground portion (knitted fabric), when sweating a large amount, clogging due to sweat at the mesh hole portion is suppressed, and an effect of maintaining a gas flow (air-through effect) is obtained.

  The air-through effect can also be obtained by using a synthetic fiber having an irregular cross section such as a flat cross section. This effect is manifested by excellent sweat-absorbing quick-drying property due to the irregular cross-sectional shape of the synthetic fiber. As a measure of water absorption, a water absorption rate dropping method based on JIS-L-1907 is used. The dough of the present invention preferably has a value determined by the water absorption rate dropping method of 3 seconds or less and a diffusive residual moisture content of less than 10% after 50 minutes. More preferably, the value of the water absorption rate dropping method based on JIS-L-1907 is 2 seconds or less, and the diffusive residual moisture content is less than 8% after 50 minutes.

  Moreover, it is preferable to form unevenness on the skin surface side of the ground portion of the fabric of the present invention. The unevenness formed on the skin surface side enhances the ability to separate the skin, thereby promoting the generation of turbulent flow and maintaining the cooling feeling (turbulent flow effect). That is, when unevenness is formed on the skin surface side of the fabric, it is possible to prevent destruction of the space in the clothes due to the fabric sticking to the skin due to the ability to leave the skin. Moreover, since the unevenness | corrugation in the skin surface side disturbs the airflow which generate | occur | produced in clothes strongly, it becomes easy to move a still air layer. The unevenness on the skin side of these fabrics may be formed by a woven or knitted structure, or may be formed by dot printing made of a resin.

The fabric obtained by the present invention can be combined with various functional processing such as antibacterial deodorization processing, deodorization processing, UV cut processing, antistatic processing, moisturizing processing, cool processing, fragrance processing, insect repellent processing, flame retardant processing, etc. good.
In addition, when the fabric structure of the present invention and the fabric portion without the mesh hole are combined in the same fabric and the garment is created, the fabric structure of the present invention partially exists such as the back and side portions. In use, it may be used to obtain a cooling effect by airflow more efficiently.

  Next, although an example and a comparative example are made into a representative example and the present invention is explained concretely, the present invention is not limited to these. In addition, about evaluation of this invention, it measured by the following method.

(1) The average area per mesh hole part and the area ratio of the mesh hole part (a) When the shape of the mesh hole part is simple and regularly arranged in a uniform size (i) 1 piece The area of the mesh hole part was expanded under no tension, photographed with a microscope, measured for dimensions and shape, and calculated.

(Ii) Area ratio of mesh hole portion The fabric was spread under no tension, photographed with a microscope, the area of the mesh hole portion, the number in the field of view, and the area of the field of view were calculated.
Mesh hole area ratio (%)
= (Area of mesh holes per piece x number of mesh holes in the field of view)
× 100 / area of field of view

(B) When the mesh hole has a complicated shape, uneven size, or irregular arrangement The cloth is spread under no tension, and the mesh hole takes a picture of the surface of the cloth with a microscope. To do. At this time, an image to be photographed includes at least eight complete mesh hole portions. Further, when the number of mesh hole portions in the measurement visual field is small, the number of photographs is increased.

  This photo is directly overlaid with an A4 OHP film, and the photo is fixed to the OHP film with tape from the back side. When the OHP film is enlarged and copied, a scale serving as a reference for the length is written on the OHP film. Next, the OHP film is turned upside down, and the outline of the mesh hole portion and the outline of the missing mesh hole portion are written with magic so that the OHP film does not include the missing mesh hole portion. Next, the inside (measuring visual field) of the outline of the mesh hole portion is painted black using a magic so as not to become a spot.

Next, an average area and a total area per black portion (mesh hole portion) are calculated using an image analysis device.
The area ratio of the mesh hole portion is calculated by the following formula.
Mesh hole area ratio (%)
= (Total area of mesh holes in measurement field x 100 / area of measurement field)

(2) Skin surface temperature change (ΔTW) in exercise evaluation wearing fabric
A temperature / air velocity sensor (Degree C) was fixed to the back of the hand so that the detection direction was horizontal to the back of the hand. Place the hand with the sensor fixed in a constant temperature and humidity room at 25 ° C and 50% RH in a bag (13cm x 25cm) made of the evaluation fabric and let it stand for 3 minutes and stabilize the environment. The movement of reciprocating the hand at an angle of 90 ° for 120 minutes was performed for 3 minutes, and the temperature and air velocity between the fabric and the skin at that time were measured.
The skin surface temperature change ΔTW when the dough was worn was calculated from the absolute value of the amount of decrease in temperature between the dough and the skin during exercise when the temperature between the dough and the skin after 3 minutes of rest was zero. In addition, the graph which shows the temperature change of the surface of the skin in the exercise | movement evaluation which wore cloth is shown in FIG.

(3) Skin surface temperature change (ΔTS) during exercise evaluation when not worn
A temperature / air velocity sensor (Degree C) was fixed to the back of the hand so that the detection direction was horizontal to the back of the hand. The hand holding the sensor in a constant temperature and humidity room at 25 ° C and 50% RH is stationary for 3 minutes, and then reciprocates at a 90 ° angle for 120 minutes for 3 minutes. The skin surface temperature and air velocity at that time Was measured.
The temperature change ΔTS of the skin surface when not worn is calculated from the absolute value of the temperature decrease amount of the skin surface after 3 minutes of exercise when the skin surface temperature after 3 minutes of rest is 0, and ΔTS = 1 Obtained 2 ° C. The graph which shows the temperature change of the skin surface in the exercise | movement evaluation at the time of non-wearing is described in FIG.

(4) Air permeability Based on JIS-L-1018, it measured with the fragile type tester.

(5) Water absorption It measured by the water absorption speed dropping method based on JIS-L-1907.

(6) Diffusive residual moisture content The dough was cut into a size of 10 cm x 10 cm, and the mass of the dough sample adjusted in a standard state (20 ° C x 65% RH) was measured (W0). Next, the sample was spread under no tension, and the mass of the dough sample after 0.6 mL of water was dropped into the center of the dough sample was measured (W1). Then, the mass of the dough sample after 50 minutes was measured with the dough sample suspended (W2). From these measured values, the diffusible residual moisture content of the dough was calculated from the following equation.
Residual moisture content (%) = (W2−W0) × 100 / (W1−W0)

(7) Cool sensation during exercise In a constant temperature and humidity chamber at 25 ° C. and 50% RH, put a hand (13 cm × 25 cm) bag made of a fabric sample and perform a sensory evaluation of the cold sensation when reciprocating. It was.
For the sensory evaluation, a questionnaire based on a five-step SD method from “cool” to “warm” was performed according to the following criteria, and the values of five subjects were averaged. In addition, the cooling sensation when the fabric was not worn was set to the standard 0 (neither).
-2: Feel cool -1: Feel slightly cool 0: Neither 1: Feel slightly warm 2: Feel warm
