Description

Clothing fabrics and clothing using the fabrics

The present invention relates to a cloth for clothing and clothing using the cloth. In more detail, it relates to a clothing fabric that can be worn comfortably even when sweating, and clothing using the fabric.

In sports accompanied by sweating, it is more comfortable to wear clothes that cope with sweating. Conventional clothing will form a water (sweat) film on the surface of the cloth in a wet state such as sweating, which will reduce the air permeability, thereby preventing the vaporization of sweat on the skin. This state can lead to the following problems: increased ineffective sweating, decreased exercise performance due to increase in deep body temperature, and increased discomfort. As a conventional technique, patent documents 2 to 3 propose knitted fabrics with meshes, and patent documents 1 and 4 propose to attach a water-repellent agent to the mesh knitted fabrics.

The present invention is a cloth for clothing, which has through holes penetrating in the thickness direction of the cloth, and the through holes are arranged in one direction of the cloth. The so-called one direction can be any one of the longitudinal direction, the transverse direction, and the oblique direction of the cloth, but it is preferably arranged in the longitudinal direction or the transverse direction. The reason is that when the garment is made, the through holes are preferably arranged in the longitudinal direction. In the case of arranging in the horizontal and diagonal directions, if the The holes appearing in the longitudinal direction at regular intervals can also ensure the performance of the present invention. The cloth can be any cloth such as woven fabric and knitted fabric. A water-repellent or hydrophobic area is arranged in at least a part of the through hole, and a hydrophilic area is arranged in the other part. In the above, the term "at least a part in contact with the through hole" means 10% or more, preferably 20% or more, and more preferably 30% or more. With this structure, the water easily moves from the vicinity of the through hole to the hydrophilic region, and no water film is formed in the vicinity of the through hole. As a result, the above-mentioned cloth for clothing can provide a cloth for clothing and a clothing using the cloth which can ensure the air permeability of the through holes even in a state of being moistened by sweat, so as to increase the effective amount of perspiration without deteriorating sports performance. , Can be worn comfortably even when sweating. The planar shape of the through hole can be any shape of a circle, an ellipse, a quadrilateral, a rhombus, a triangle, a polygon, and an irregular shape.

The cloth of the present invention is provided with a water-repellent or hydrophobic area in a part of the through hole, and the surface tension of the through hole is increased by the capillary phenomenon of the through hole. As a result, the moisture on the surface of the cloth can easily move, and a water film cannot be formed in the through hole. Also, even if the through hole is filled with water, because some part is a hydrophilic area and the other part is a water-repellent or hydrophobic area, the surface tension is different. Therefore, the balance of the force exerted by the water in the through hole is not uniform, so it cannot be The through holes form a water film. It is preferable to arrange a water-repellent or water-repellent area around the through hole so as to be in contact with at least a part of the through hole. In a part of the fabric, a hydrophilic area is arranged in a way that can absorb the sweat discharged from the body surface. The hydrophilic area is preferably configured to be at least 10% or more. The water-repellent or water-repellent area can be constructed by weaving yarns in a water-repellent or water-repellent state, or by coating a cloth with a water-repellent or water-repellent resin. The hydrophilic region can be constructed by weaving a hydrophilic yarn, or by coating a cloth with a hydrophilic resin.

In the fabric of the present invention, a water-repellent or hydrophobic yarn is arranged in a part of the through hole, and the surface tension of the through hole is increased by the capillary phenomenon of the through hole. The moisture on the surface of the fabric is easy to move, and the water film cannot be formed in the through hole. It is preferable to arrange a water-repellent or hydrophobic yarn around the through hole so as to be in contact with at least a part of the through hole. On a part of the fabric, a hydrophilic yarn is arranged in a way that can absorb the sweat discharged from the body surface. The hydrophilic yarn is preferably configured at least 10% above.

When the cloth is installed in a direction perpendicular to the ground, it is also possible to install a line where water can easily flow in the vertical direction. The lines in the vertical direction are formed by densification of yarn density or continuous water-repellent or hydrophobic areas. To make up the density of the yarn, it is necessary to use the loop density of the fabric, the number of twists of the yarn, the crimp rate, the knitting method, and the embossing process. To form a continuous water-repellent or water-repellent area, there are states such as knitting a continuous arrangement of water-repellent yarns or water-repellent yarns, such as a state in which water-repellent yarns or water-repellent yarns are continuous, or water-repellent or water-repellent Printing process, for example, a state in which the printing process is performed in a stripe shape. A certain fixed-length line can also appear repeatedly. The line can be not only a straight line, but also a wave-shaped curve.

In the present invention, at least one fiber yarn (I) selected from the group consisting of water-repellent fiber yarn and hydrophobic fiber yarn, such as hydrophobic fiber yarn including polypropylene fiber yarn, polyethylene fiber yarn, and polyester (PET etc.) yarn, The organic fiber yarn (for example, the above-mentioned hydrophobic fiber yarn) is a yarn obtained by water-repellent processing, and the yarn portion obtained by water-repellent processing is printed in a fabric state. Hydrophilic fiber yarn (II) includes cotton spinning, rayon and other cellulose fiber spinning, highly cross-linked polyacrylate fiber spinning, blended yarn of these fibers and polyester (PET, etc.) fibers, and such fibers Composite spinning with polyester (PET, etc.) multifilament yarns (including worsted and twisted yarns), nylon yarns, polyester (PET, etc.) fiber yarns obtained by hydrophilic processing, etc., printed and hydrophilic processed in fabric state Yarn part. As an example, at least one fiber yarn (I) selected from the group consisting of water-repellent fiber yarn and hydrophobic fiber yarn may be used as the fiber constituting the through hole, and the hydrophilic fiber yarn (II) may be used for the part of the cloth.

The part where the hydrophilic fiber yarn is used should preferably absorb water within 180 seconds in the drip method evaluation (JIS L 1907 A method). More preferably, it is within 60 seconds. It is preferable that when the drop method evaluation (JIS L 1907 A method) is performed on the fabric of the present invention, the part using the hydrophilic fiber yarn retains more water than the part using the water-repellent fiber yarn and the hydrophobic fiber yarn.

In the fabric of the present invention, the water-repellent or hydrophobic area (A) and the hydrophilic area (B) occupy The area of the clothing fabric is preferably A:B=1:99 to 90:10, more preferably 2:98 to 85:25, and particularly preferably 2:98 to 80:20. Here, the area of the water-repellent or water-repellent area (A) in the case of a continuous arrangement of water-repellent yarns or water-repellent yarns, such as warp-knitted water-repellent yarns or continuous water-repellent yarns, refers to the use of a digital microscope (product model VH -Z25, manufactured by KEYENCE company) measured by measuring the thickness of the yarn in the state of unloaded fabric multiplied by the number of yarns constituting the fabric per unit area. In addition, when resin is applied to the water-repellent or water-repellent area to form the water-repellent or water-repellent area (A), it refers to the coating area of the resin per unit area. The area other than the water-repellent or hydrophobic area (A) is set as the hydrophilic area (B), and the area ratio of the water-repellent or hydrophobic area (A) to the hydrophilic area (B) is calculated based on this. In addition, the ratio of at least one fiber yarn (I) selected from the water-repellent fiber yarn and hydrophobic fiber yarn to the hydrophilic fiber yarn (II) is preferably A:B when the clothing fabric is set to 100% by mass =1:99 to 90:10, more preferably 2:98 to 85:25, particularly preferably 2:98 to 80:20. Thereby, it becomes a state in which water can move more easily, and a water film is not formed near the through hole.

As a preferred aspect, when the through hole is suspended in a vertical direction in a state where the weight of the cloth for clothing of the present invention is 100% moist with 300% moisture, the through hole maintains a gap.

The clothing fabric of the present invention preferably has a groove (line) formed in the same direction as the through holes arranged in one direction, and the water-repellent or hydrophobic area is preferably at least a part of the groove. With this, when the amount of sweating increases, water easily flows from the groove (line). The groove (line) direction is preferably set as the height direction. In addition, the groove width is preferably 0.1 to 30 mm, and more preferably 0.3 to 20 mm. The groove portion (line) is preferably formed in a cloth portion composed of at least one fiber yarn (I) selected from a water-repellent fiber yarn and a hydrophobic fiber yarn. The reason is that the water becomes easy to flow. Regarding the aforementioned grooves, since the braid part of the hydrophilic fiber yarn is formed relatively thickly, and the braid part of the water-repellent fiber yarn or the hydrophobic fiber yarn is formed relatively thinly, the water-repellent fiber yarn or hydrophobic fiber can also be formed relatively thickly. The knitted fabric part of the yarn serves as the groove.

Regarding the size of the through hole, both the longitudinal and lateral lengths are preferably an average of 0.3 mm or more and 25 mm or less, and more preferably 0.3 to 20 mm. Thereby, it is possible to provide a cloth for clothing that can further increase the effective amount of perspiration without deteriorating sports performance, and can be worn comfortably when sweating, and a clothing using the cloth.

The opening rate of the aforementioned clothing fabric is preferably 1% or more and 50% or less, and more preferably 2-40%. Thereby, it is possible to provide a cloth for clothing that can further increase the effective amount of perspiration without deteriorating sports performance, and can be worn comfortably when sweating, and a clothing using the cloth. Furthermore, the so-called aperture ratio refers to the ratio occupied by the through holes in the fabric.

The fiber yarn used in the cloth for clothing of the present invention may be any of spun yarn, multifilament yarn, crimped yarn obtained by processing the multifilament yarn, and the like. In the case of using crimped yarns, it is preferable to arrange yarns with different crimping ratios up and down. If the curling rate is high, the water retention capacity becomes larger, and if the curling rate is low, the water retention capacity becomes smaller. By arranging it equal to the vertical direction, the water particles become larger, and the movement of the water particles is accelerated by repetition. Can ensure clearance. When a twisted yarn is used, it is preferably composed of two or more different yarns whose twist number is 100 times/m or more.

The cloth of the present invention can be a woven fabric or a knitted fabric. As a woven fabric, plain weave, twill weave, satin weave, change plain weave, change twill weave, change satin weave, composite weave, jacquard weave, single weave, double weave, multiple weave, warp pile weave , Weft pile weave, leno weave, etc. as the basis, through holes are formed along one of the longitudinal, transverse, and oblique directions. Knitted fabrics include circular knitting, weft knitting, warp knitting (including Tricot warp knitting, Raschel warp knitting), pile knitting, etc., with plain knitting, Tianzhu knitting, rib knitting, and double rib knitting ( Double-sided knitting), threaded organization, double-reversed organization, warp plain weave, warp fleece weave, satin weave, chain weave, interlining weave, etc., through holes are formed along one of the longitudinal, horizontal, and oblique directions. Among them, knitted fabrics are preferred. In the case of a knitted fabric, the texture or loop stretches in the plane direction when wet, and the air permeability becomes high. In addition, the weight per unit area (weight per unit area) is also lighter, so it is suitable for clothes that sweat more. As the knitted fabric, knitted fabrics such as tricot, raschel, etc., warp knitted fabrics, weft knitted fabrics, and circular knitted fabrics are preferred. In the present invention, the preferable unit area weight of the fabric is 40 g/m ² or more and less than 300 g/m ² . Since it is used in the sweat-prone part of clothes, it is preferably a thin cloth. The fabric of the present invention can be unidirectional or bidirectional, and can also contain elastic yarns such as polyurethane.

The clothing of the present invention includes the above-mentioned cloth, and the cloth portion is arranged with through holes penetrating in the thickness direction along the height and oblique directions. Thereby, the moisture of sweat is easy to flow in the longitudinal direction, and the air permeability of the through holes is ensured. The clothing is preferably made into sports clothing. It is especially suitable for sportswear used in hot periods when sweating is a lot. The above-mentioned cloth is arranged on at least the part of the human body that sweats more to make clothes. For example, it can be used for all of sports shirts, T-shirts, underwear, training thermal clothes, briefs, ordinary shirts, briefs, etc., and can also be used for parts such as underarms and back.

Hereinafter, a cloth for clothing of a preferred embodiment of the present invention will be described using drawings. In the following drawings, the same symbol represents the same thing. Fig. 1A is a schematic explanatory diagram showing the movement of sweat in a normal state of conventional clothing. The sweat 13a, 13b produced by the skin 11 diffuses from the gap part of the garment 12a to the outside air side. 14 is the flow of air. Fig. 1B is a schematic explanatory diagram showing the movement of sweat in a state of heavy sweating of conventional clothes. In a state of profuse sweating, the moisture of the clothes becomes larger and a water film is produced. The voids of the garment 12b will disappear or become less. Sweat 13 and air remain on the surface of the skin 11. Ineffective sweating increases, and exercise is caused by the rise of deep body temperature. The performance drops and the discomfort becomes higher.

On the other hand, FIG. 1C is a schematic explanatory diagram showing the movement of sweat in a state where a large amount of sweat is produced in the clothing according to one embodiment of the present invention. Even if it becomes a state of a lot of sweating and the wetness of the clothes becomes larger, the gaps of the through holes are also ensured, so the formation of water film is suppressed, and the air permeability of the fabric 12C is ensured, so that the sweat 13a, 13b from the skin 11 will flow from the gaps of the clothing 12c The part diffuses to the outside air side. In addition, the sweat on the skin is always vaporized on the surface of the body, which can increase the effective amount of perspiration without degrading sports performance, and can be worn comfortably when sweating.

[Example]

Hereinafter, it demonstrates further concretely using an Example. In addition, the present invention is not limited to the following examples but explained.

(Examples 1 to 5, Comparative Examples 1 to 4)

Prepare the fabric with the content shown in Table 1. The water-repellent yarn or the hydrophobic yarn I is used to form the cloth part including the through holes, and the other part is formed by the hydrophilic yarn II. Example 1 (Development A), Example 2 (Developed product B), Comparative Example 1 (Comparative product a), Comparative Example 3 (Comparative product c), and Comparative Example 4 (Comparative product d) are for shirts, Example 3 (Developed product C), Example 5 (Developed product E) and Comparative Example 2 (Comparative product b) are for underwear. In Table 1, PET is polyethylene terephthalate fiber yarn, PP is polypropylene fiber yarn, and PU is polyurethane fiber yarn. In addition, T represents dicitex, f represents the number of threads, the count represents the metric count, and SD represents semidull. The front and back of the fabrics of the developed products A-E of Examples 1 to 5 are shown in Figure 8. Example 1, Example 2, Example 3, Example 5, and Comparative Example 4 used water-repellent yarns obtained by water-repellent processing on the surface of PET fiber yarns. In addition, Example 4 uses hydrophobic PP fiber yarn, and uses a blended yarn of PET fiber and highly cross-linked polyacrylate fiber as the hydrophilic yarn.

The aperture ratios of the example products 1 to 5 and the comparative example products 1 to 2 were measured. The aperture ratio was measured by the following method.

(1) The image of the printed fabric is cut out of the line segment that connects the centers of the 4 through holes Into the quadrilateral range.

(2) Measure the paper weight W ₁ of the cut out quadrilateral part.

(3) Cut out the through hole that enters the cut out quadrilateral part, and measure the paper weight W ₂ .

(4) Calculate using aperture ratio=(1-W ₂ /W ₁ )×100.

Table 2 summarizes the aperture ratio of each fabric.

The air permeability resistance when dry and when wet is measured. The air permeability resistance tester KES-F8 (manufactured by Katotech) was used for the measurement. This measurement is performed by releasing air to the atmosphere or sucking air from the atmosphere, detecting the pressure at the time of release and suction, and calculating the air permeability resistance R.

Air permeability: 4cc/cm ² /sec. (fixed air permeability)

Area of ventilation holes: 2π cm ²

The air permeability resistance during drying is measured under the conditions of a temperature of 20°C and a relative humidity of 65% R.H. in the state of drying the fabric.

The air resistance when wet is measured by making the air release and suction direction parallel to the ground under the condition of 100% wet and 300% moisture relative to the mass of the fabric. The temperature and humidity are the same as above. The measurement method is as follows.

(1) Make the cloth vertical to the ground.

(2) Take out the sample immersed in the water tank, and set the cloth in the testing machine.

(3) Start the measurement by the method according to the KES test guide.

Table 3 summarizes the air resistance value of each fabric.

It is clear from Table 3 that, compared with the comparative example, the air permeability resistance value of the product of this example is lower both when dry and when wet, especially when the air resistance value is significantly lower when wet. If the air resistance value when wet is ^{less than 0.1kPa*s/m 2} , you can get the body feeling of moisture detaching from the inside of the clothes to the outside of the clothes.

The heat transfer to the outside air in a wet state was measured. The heat dissipation of the clothes during sweating was measured. Set as constant temperature and humidity layer: 80°C, relative humidity: 95% R.H., using machine: heat flow sensor Z (product model: 2015TC, manufactured by Hioki Electric Co., Ltd.). The measuring device is shown in Figs. 9A-C, and the measuring method is as follows.

(1) Install the sample on the edge of the cup, and make the back side of the cloth become the constant temperature and humidity layer side at this time.

(2) Immerse the sample in ion exchange water for more than 1 minute.

(3) Take out the sample from the water in such a way that the warp direction of the cloth becomes the vertical direction, and place it at the blowing port of the constant temperature and humidity layer within 5 seconds.

(4) The measurement is started 5 seconds after the sample is taken out of the water.

(5) The measurement ends in 1 minute and 30 seconds in total.

(6) The analysis system calculates the integral value 1 to 15 seconds after the start of the measurement.

The heat flow value of each fabric is summarized and shown in Table 4 (shirt fabric) and Table 5 (underwear fabric).

As shown in Table 4 and Table 5, it can be seen that the products of Examples 1-3 (Development Products A and B) have a higher heat flow value and are correspondingly more comfortable to wear.

Next, the measurement of the amount of heat transfer to the outside air in a wet state was performed to measure the heat dissipation of the clothes during sweating. The machine used is set as the heat flow sensor Z (product model: 2015TC, manufactured by Hioki Electric Co., Ltd.).

(1) Prepare a sample obtained by switching the comparison product and the developed product left and right, and install the heat flow sensor as shown in Figure 10. At this time, the heat flow sensor is set up with a space of 3mm between the clothes and the clothes, and the direction of heat movement from the inside to the outside of the clothes is set to +.

(2) Run for 30 minutes on a treadmill set at a speed of 5 min/km in an environmental test room set at an ambient temperature of 28°C and 80% RH. At this time, assuming that you are running, a wind of 2.5 m/s is blown from the front.

(3) The analysis system calculates the integral value of the heat transfer for a total of 5 minutes from 25 to 30 minutes after the start of the measurement.

The above results are shown in Table 6.

In the case of the comparison product, 15 to 20 minutes after the start of running when the subject wipes sweat and the clothes are completely wetted, the heat starts to move from the inside of the clothes to the outside air, and some values are displayed as negative. In contrast, in the case of the product of this embodiment (development product), even if the sweat is wiped off and the clothes are completely moistened, Perspiration can be maintained by evaporating sweat to dissipate heat to the outside. Therefore, the value is always displayed as positive.

Next, a shirt was sewn using each fabric, and a wearing test was performed. The wearing test was conducted in the Kansai area in August with the development and comparison products. Sensory tests (SD method, two-pole scale, 5-stage) were used to evaluate the wearing feeling when sweating heavily.

. The subject was a healthy Japanese male between 20 and 40 years old.

. The monitoring system is carried out by running at 5 min/km and 30 minutes.

. The scoring system is based on the normal feeling during exercise.

. Nothing is worn on the skin side of the more developed products.

. The evaluation is based on (1) the wet area of the fabric (the wider the worse), (2) the sweat-absorbent and quick-drying, (3) the stickiness, (4) the breathability, (5) the time to wipe the sweat (the earlier the worse), (6) It is comfortable to wear. The evaluation standard system is set as -2 (poor), -1 (slightly poor), 0 (fair), 1 (slightly better), 2 (good).

Fig. 11 and Fig. 12 show graphs of the results of the wearing test of the shirts of the present example and the comparative example. It can be seen from Fig. 11 and Fig. 12 that compared to the comparative product, the developed product has better air permeability when the clothes are wetted by sweating, and it can be confirmed that the concept of the product of the present invention can be experienced.
