Description

The present invention relates to double raschel knitted fabrics and garments.

Conventionally, natural fibers such as cotton, which have excellent moisture absorption and desorption properties, have been used to keep the environment inside clothes comfortable. However, once the body sweats, the clothes do not dry easily and become sticky, resulting in a large amount of sweating. Synthetic fibers with excellent sweat treatment properties are widely used in the assumed scenes. In addition, there are many clothes that use highly breathable woven and knitted fabrics to prevent hot air from being trapped inside the clothes. However, in a windy environment such as indoors, the hot air that is trapped inside the clothes is removed from the clothes. The effect of discharging was insufficient.

As a garment that keeps the environment inside the garment comfortable, for example, a garment using double raschel knitted fabric in whole or in part has been proposed (see Patent Document 1). According to this proposal, since the double raschel knitted fabric has high breathability, the hot air inside the garment can be discharged to the outside of the garment through the portion of the double raschel knitted fabric.

Further, in recent years, clothes in which a blower fan is mounted on a fabric having low air permeability have been proposed (see Patent Document 2). According to this proposal, the blower fan blows outside air into the garment to greatly inflate the garment made of low-breathable fabric, thereby removing the hot air inside the garment from the openings of the garment such as the collar, cuffs, and hem. It is said that it can be forcibly discharged out of clothes.

Further, a garment equipped with a blower fan in which a bag-shaped sheet is laid in the garment has been proposed (see Patent Document 3). According to this proposal, the bag-shaped sheet creates a space inside the clothes, and the outside air can be sent into the clothes from the blower fan through the bag-shaped sheet, and the hot air inside the clothes can be efficiently discharged to the outside of the clothes. There is. In addition, since the outside air can be supplied to individual parts of the body through the bag-shaped sheet, it is possible to limit the cooling to the parts where the wearer does not need cooling.

Further, a three-dimensional knitted fabric in which unevenness of a wide portion and a narrow portion composed of a double raschel is formed in the longitudinal direction has been proposed (see Patent Document 4). According to this proposal, by using it on the back part of the bag, the moisture of the contact part with the body in the bag can be surely released to the outside.

Japanese Patent No. 5521170 International Publication No. 2017/006481 JP-A-2017-36535 JP-A-2018-57518

It is known that in the environment inside clothes, the specific gravity of the air heated inside the clothes by the body temperature becomes small, so that the so-called chimney effect that an updraft is generated inside the clothes is exhibited.

In the method described in Patent Document 1, it is stated that the hot air inside the garment can be discharged to the outside of the garment by using the double raschel knitted fabric having high air permeability for all or a part of the garment. However, since the control of the airflow inside the garment such as the chimney effect developed in the garment is not considered, the cooling effect cannot be obtained when the wearer does not give sweat or moisture, and it is rather thick in a windless environment. Since the double raschel knitted fabric works as a heat insulating material, it does not become a comfortable garment, and there is a problem in designability when it is used in a wide range of garments.

According to the method described in Patent Document 2, outside air can be blown into clothes made of a cloth having low air permeability by a blower fan, and hot air in the clothes can be forcibly discharged to the outside of the clothes. However, in order to forcibly discharge the hot air inside the clothes to the outside of the clothes, it is necessary to mount a powerful blower fan, and there is a problem that the clothes swell greatly and the wearing feeling and the design are impaired. Further, the powerful blower fan has a problem that it has a large noise. Further, since the clothes are made of a fabric having low air permeability, there is a problem that when the blower fan is stopped, the feeling of heat and stuffiness becomes high.

According to the method described in Patent Document 3, it is possible to blow air to individual parts desired by the wearer, and the body of the wearer can be reasonably cooled. However, in everyday wearing scenes such as offices and homes, there is a problem that when the outside air blown from the blower fan passes through the bag-shaped sheet in the clothes, the clothes swell and the design is impaired. .. In addition, since it is essential to double the fabric in order to create a space inside the clothes with the bag-shaped sheet, there is a problem that the feeling of heat and stuffiness becomes high when the blower fan is stopped. It was.

According to the method described in Patent Document 4, by using a double raschel having an uneven structure on the back support portion of the bag, moisture in the contact portion between the body and the body of the bag is discharged to the outside through a formed recess. However, it is said that the uneven portion alternately forms a wide portion and a narrow portion, the flow of the airflow due to the chimney effect is not linear in the longitudinal direction, and the width and depth of the uneven portion are not sufficiently considered, so that the humidity It was hard to say that the release was effective.

Here, in the case of a wearing scene such as an outdoor construction site in the summer or indoors of a factory where air conditioning is not effective, there was swelling of clothes and noise from a blower fan by the methods described in Patent Documents 2 and 3. However, it was not suitable for the wearing scene of being worn indoors such as offices and homes.

An object of the present invention is to solve the above technical problems and to provide a double raschel knitted fabric capable of forming a ventilation flow path inside the garment by laying it inside the garment, and to provide the ventilation flow path. By efficiently discharging the hot air inside the clothes to the outside of the clothes through the clothes, the environment inside the clothes can be kept comfortable, and the wearing feeling and design are also excellent, so in various wearing scenes where comfort is required. The purpose is to provide garments that can be suitably used.

The above object is the present invention, that is, a double raschel knitted fabric having a middle layer composed of a front surface structure, a back surface structure, and a knotted structure, and at least a part of the middle layer is composed of fibers A having a single yarn fiber diameter of 150 to 300 μm. , At least a part of both the front surface structure and the back surface structure is composed of fibers B having a single yarn fiber diameter of 10 to 30 μm, and the thickness Da of the double raschel knitted fabric is 5 to 15 mm. In, convex bodies having a thickness of Da are linearly and continuously formed in the warp direction, the width La of the convex bodies does not substantially change in the warp direction of the knitted fabric, La is 10 to 50 mm, and the surface structure is Alternatively, it can be solved by a double raschel knitted fabric characterized in that the width Lb of the back surface structure is wider than that of the convex body.

Further, it is preferable that the double raschel knitted fabric is connected in a sheet shape by fibers constituting the front surface structure or the back surface structure, and the distance Lc between two adjacent convex bodies is 5 to 100 mm.

The double raschel knitted fabric of the present invention can also be suitably adopted for clothes laid on at least a part of the inside of clothes and clothes laid around the neck inside the clothes.

Further, the garment of the present invention has at least one air intake port for taking in outside air into the garment, and the air intake port is made of a cloth or a hole having an air permeability of 200 to 800 cc / cm ² / sec. It is also preferably possible to use a fastener type ventilation mechanism for the intake port and to provide a blower unit for taking in outside air between the clothes and the body.

According to the present invention, it is possible to provide a double raschel knitted fabric capable of forming a ventilation flow path inside the garment by laying it inside the garment. In addition, since the hot air inside the clothes can be efficiently discharged to the outside of the clothes through the ventilation flow path, the environment inside the clothes can be kept comfortable, and the wearing feeling and design are excellent, the environment is high temperature and / or high humidity. It can be suitably used in various wearing scenes such as offices and homes where comfort is required.

FIG. 1a is a perspective view showing a double raschel knitted fabric having one convex body in the present invention, FIG. 1b is a front view thereof, and FIG. 1c is a side view thereof. FIG. 2a is a perspective view showing a portion of the double raschel knitted fabric having two or more convex bodies in the present invention including three convex body portions, FIG. 2b is a front view thereof, and FIG. 2c is a side surface thereof. It is a figure.

The double raschel knitted fabric of the present invention is a double raschel knitted fabric having a middle layer composed of a front surface structure, a back surface structure and a knotted structure, and fibers A having a single fiber diameter of 150 to 300 μm constitute at least a part of the middle layer. However, the fiber B having a single yarn fiber diameter of 10 to 30 μm constitutes at least a part of the front surface structure and the back surface structure, and the thickness of the double raschel knitted fabric is 5 to 15 mm, and the thickness of the double raschel knitted fabric is 5 to 15 mm. The Da is 5 to 15 mm, and convex bodies having a thickness of Da are linearly and continuously formed in the warp direction, and the width La of the convex bodies does not substantially change in the warp direction, and La is 10 to 50 mm. The width Lb of the front surface structure or the back surface structure is wider than that of the convex body.

Generally, when the fabrics that make up clothes are in close contact with the body, a feeling of heat or stuffiness is felt. The reason is that when the fabric is in close contact with the body, the fabric inhibits the generation of airflow inside the clothes, and the immovable air layer existing inside the fabric provides a heat retaining effect. In particular, in an indoor environment such as an office or home in the summer, when wearing loose underwear, it is easier for the heat to stay in the clothes and the coolness to be felt, rather than the underwear in which the fabric adheres to the body. On the other hand, even if there is room in the clothes, if there is no passage or part where the hot air trapped inside the clothes can be discharged to the outside of the clothes, the hot air will stay inside the clothes, and you will feel the feeling of heat and stuffiness. It ends up.

Therefore, as a result of diligent studies on the control of the air flow inside the clothes to efficiently discharge the hot air inside the clothes to the outside of the clothes, the present inventors formed a ventilation flow path inside the clothes by laying them inside the clothes. We have found a double raschel knitted fabric of the present invention that can. It is desirable that the ventilation flow path is formed of a fiber structure made of a fiber material in consideration of skin contact and wearing feeling. Further, in order to enhance the function of the ventilation flow path, it is desirable that the fiber structure has a sufficient thickness and maintains the thickness. Here, in order to form a fiber structure having a sufficient thickness and maintain its morphology, it is best to use a double raschel knitted fabric classified as a warp knit, among many woven and knitted structures. I came up with the idea that it is suitable.

The fiber A constituting at least a part of the middle layer of the double raschel knitted fabric of the present invention has a single yarn fiber diameter of 150 to 300 μm. The single yarn fiber diameter in the present invention refers to a value measured by the method described in Examples. When the single yarn fiber diameter of the fiber A is 150 μm or more, it is possible to suppress crushing when the double raschel knitted fabric is laid inside the garment and worn, and the thickness of the double raschel knitted fabric is maintained. Can be done. As a result, the function of the ventilation flow path is exhibited, the hot air inside the clothes can be efficiently discharged to the outside of the clothes, and the environment inside the clothes can be kept comfortable. In addition, it is possible to sufficiently maintain the recoverability when the double raschel knitted fabric is compressed from the outside in the vertical direction, that is, in the thickness direction. It is particularly preferable that the single yarn fiber diameter of the fiber A is 160 μm or more. On the other hand, when the single yarn fiber diameter of the fiber A is 300 μm or less, it is possible to suppress a decrease in the skin contact of the front surface structure and / or the back surface structure constituting the double raschel knitted fabric. When laid on the floor and worn, the clothes will not feel uncomfortable and will be comfortable to wear. The single yarn fiber diameter of the fiber A is more preferably 280 μm or less, and further preferably 260 μm or less.

The fiber A used in the present invention is not particularly limited as long as it satisfies the range specified in the present invention with respect to the form of the fiber, but it is preferably a monofilament from the viewpoint of shape retention.

By using the fiber B for at least a part, preferably all, and at least a part, preferably all of the front surface structure of the double raschel knitted fabric, the shape retention of the front structure and the back structure of the double raschel knitted fabric is ensured. Further, it is preferable because it can be tailored to have a soft and comfortable texture as a skin contact. The single yarn fiber diameter in the present invention refers to a value measured by the method described in Examples described later. When the single yarn fiber diameter of the fiber B is 10 μm or more, the process passability is good, and when the double raschel knitted fabric is laid inside the clothes and worn, it may be scratched against the body or used as a knitted fabric. It is preferable because it has excellent shape retention, less fluffing due to rubbing when washing the double raschel knitted fabric, and excellent durability. The single yarn fiber diameter of the fiber B is more preferably 12 μm or more, and further preferably 14 μm or more. On the other hand, when the single yarn fiber diameter of the fiber B is 30 μm or less, when the double raschel knitted fabric is laid inside the garment and worn, a smooth skin contact due to the front surface structure or the back surface structure of the double raschel knitted fabric can be obtained. It is preferable because it makes the clothes comfortable to wear. The single yarn fiber diameter of the fiber B is more preferably 28 μm or less, and further preferably 26 μm or less.

Among them, polyester fibers and polyamide fibers have excellent mechanical properties, so they have good process passability such as knitting of double raschel knitted fabric and sewing of laying double raschel knitted fabric inside clothes, and are used. It is preferable because it has excellent durability at the time. Further, the polyester fiber is excellent in moldability and heat setting property, and therefore can be more preferably adopted.

The fiber B used in the present invention is not particularly limited as long as it satisfies the range specified in the present invention, and may be any of monofilament, multifilament, staple, spun yarn, etc., and false twist, twisted yarn, etc. May be processed.

The fibers A and B used in the present invention are not particularly limited in terms of the cross-sectional shape of the fibers, and may have a perfect circular cross section or a non-circular cross section. Specific examples of the non-circular cross section include, but are not limited to, a multi-leaf shape, a polygonal shape, a flat shape, and an elliptical shape.

The double raschel knitted fabric of the present invention will be described below with reference to FIGS. 1 and 2. FIG. 1a is a perspective view showing a double raschel knitted fabric having one convex body in the present invention, FIG. 1b is a front view thereof, and FIG. 1c is a side view thereof.

It is a figure.

The double raschel knitted fabric 1 of the present invention has a middle layer 4 composed of a front surface structure 2, a back surface structure 3, and a connecting structure, and a convex body 7 is linearly and continuously formed. Since at least a part of the middle layer 4 has the middle layer 4 composed of the binding structure composed of the fibers A5, the double raschel knitted fabric can maintain a constant thickness, so that the double raschel knitted fabric is placed inside the garment. By laying it on the floor, a certain distance can be secured between the body and clothes. It is preferable that at least a part of the front surface structure 2 and the back surface structure 3 is composed of fibers B6.

The width Lb of the back surface structure of the double raschel knitted fabric in the present invention is the length of the double raschel knitted fabric in the direction perpendicular to the warp direction (the direction in which the convex body is formed) of the knitted fabric, which will be described later. Refers to the value measured by the method described in the example.

If the width of the back surface structure of the double raschel knitted fabric is 20 mm or more, when the double raschel knitted fabric is laid inside the garment and worn, a ventilation flow path can be formed inside the garment, so that the hot air inside the garment Is preferable because it can be efficiently discharged to the outside of clothes and the environment inside clothes can be kept comfortable. The width of the back surface structure of the double raschel knitted fabric is more preferably 25 mm or more, and further preferably 30 mm or more. On the other hand, when the width of the back surface structure of the double raschel knitted fabric is 300 mm or less, it is preferable because when the double raschel knitted fabric is laid inside the garment and worn, the garment does not feel uncomfortable and has an excellent wearing feeling. The width of the back surface structure of the double raschel knitted fabric is more preferably 250 mm or less, and further preferably 200 mm or less.

In the present invention, the front surface structure and the back surface structure of the double raschel knitted fabric preferably have ear tissues including chain knitting at both ends in the width direction. Regarding cutting in the warp direction of the knitted fabric, if cutting is performed using a cutting machine or scissors, there is a problem that the knitted fabric frays in the warp direction starting from the cut part. It is not preferable because there is a concern that the problem of fraying will increase due to washing. In order to avoid this problem, it is preferable that the optimum width to be used as the double raschel knitted fabric is assumed in advance, and both ends in the width direction constituting the front and back tissues of the knitted fabric are ear tissues including chain knitting.

The length of the double raschel knitted fabric of the present invention in the warp direction can be appropriately selected within a range that does not impair the wearing feeling and design of the garment, but is preferably 30 to 400 mm. The length of the double raschel knitted fabric in the warp direction in the present invention refers to a value measured by the method described in Examples described later. If the length of the double raschel knitted fabric in the warp direction is 30 mm or more, a ventilation flow path can be formed inside the garment when the double raschel knitted fabric is laid inside the garment and worn. It is preferable because hot air can be efficiently discharged to the outside of clothes and the environment inside clothes can be kept comfortable. The length of the double raschel knitted fabric in the warp direction is more preferably 50 mm or more, and further preferably 70 mm or more. On the other hand, when the length of the double raschel knitted fabric in the warp direction is 400 mm or less, the garment is preferable because when the double raschel knitted fabric is laid inside the garment and worn, the garment does not feel uncomfortable and has an excellent wearing feeling. The length of the double raschel knitted fabric in the warp direction is more preferably 370 mm or less, and further preferably 350 mm or less.

The thickness Da of the double raschel knitted fabric of the present invention is 5 to 15 mm. The thickness Da of the double raschel knitted fabric in the present invention refers to a value measured by the method described in Examples described later. If the thickness of the double raschel knitted fabric is 5 mm or more, when the double raschel knitted fabric is laid inside the garment and worn, a ventilation flow path can be formed inside the garment, so that the hot air inside the garment is efficient. It can be well discharged to the outside of clothes, and the environment inside clothes can be kept comfortable. The thickness of the double raschel knitted fabric is more preferably 6 mm or more, and further preferably 7 mm or more. On the other hand, if the thickness of the double raschel knitted fabric is 15 mm or less, the garment will not feel uncomfortable and will be comfortable to wear when the double raschel knitted fabric is laid inside the garment and worn. Further, it is possible to obtain a ventilation flow path in which the process passability of the knitting process of the double raschel knitted fabric and the thickness shape retention of the knitted fabric structure are good, the thickness unevenness is small, and the thickness uniformity is high. Further, the thickness of the double raschel knitted fabric is more preferably 14 mm or less, and further preferably 13 mm or less.

It is possible to obtain a ventilation flow path with high uniformity. Further, when the double raschel knitted fabric is laid inside the garment and worn, a ventilation flow path composed of a columnar space formed by the body and a groove-shaped depression can be formed inside the garment. Hot air can be efficiently discharged to the outside of clothes, and the environment inside clothes can be kept comfortable. The distance between the convex bodies of the double raschel knitted fabric is more preferably 12 mm or more, and further preferably 15 mm or more. On the other hand, if the width of the convex body of the double raschel knitted fabric is 50 mm or less, the garment will have an excellent wearing feeling without any discomfort when the double raschel knitted fabric is laid inside the garment and worn. The distance between the convex bodies of the double raschel knitted fabric is more preferably 45 mm or less, and further preferably 40 mm or less.

In the double raschel knitted fabric of the present invention, it is important that convex bodies are linearly and continuously formed in the warp direction of the knitted fabric, and the width La of the convex bodies does not substantially change in the warp direction of the knitted fabric. .. As a result of diligent studies on forming a ventilation flow path inside the garment, the present inventors laid a double raschel knitted fabric having a certain thickness inside the garment, and as a result, a certain distance between the body and the garment. Furthermore, it was found that the columnar space formed by the body and the knitted fabric exerts an excellent effect as a ventilation flow path by being continuously formed linearly in the warp direction of the double raschel knitted fabric. It was. Since the specific gravity of the air heated inside the clothes by the body temperature becomes small, the so-called chimney effect that an updraft is generated inside the clothes is exhibited. Therefore, in the conventional clothes having no ventilation flow path, there is a problem that hot air is trapped inside the clothes and the temperature and humidity inside the clothes rise. On the other hand, in the present invention, as described above, by laying the double raschel knitted fabric linearly and continuously formed in the warp direction of the knitted fabric inside the garment, a ventilation flow path is formed inside the garment, and the inside of the garment is formed. Since hot air can be efficiently discharged to the outside of clothes, it is possible to suppress an increase in temperature and humidity inside clothes, and the effect of keeping the environment inside clothes comfortable can be dramatically enhanced. In the above, "convex body is linearly continuously formed" means that the convex body is continuously formed in the warp direction of the knitted fabric without interruption while the thickness Da is maintained in the three-layer structure of the front surface structure, the back surface structure and the middle layer. This means that if the knitted fabric is continuously formed in the warp direction, it does not have to be strictly straight. Although the thickness Da may vary due to knitting reasons, it is considered to be the same if it is within the range of the thickness specified in the present invention by the measuring method described in the examples. Further, "the width La of the convex body does not substantially change in the warp direction of the knitted fabric" means that the width La of the convex body, which is the length of both ends in the width direction, changes in one convex body. Specifically, the method of measuring the width La will be described in the examples described later, but 10 points are measured per sample at intervals that equally divide the length of the knitted fabric in the warp direction, and the average thereof is measured. It is shown that the maximum width and the minimum width of the 10 points measured with respect to the value are both within ± 10% of the average value. When a plurality of convex bodies exist, the width La does not necessarily have to be the same among the different convex bodies.

The double raschel knitted fabric of the present invention may be laid in a state where a plurality of double raschel knitted fabrics are laid in parallel inside the garment, or two or more convex bodies 7 are formed into a sheet by fibers constituting the front surface structure 2 or the back surface structure 3. It may be a structure having a groove 9 which is a groove-shaped recess 8 formed by two adjacent convex bodies 7 connected to each other.

Hereinafter, the present invention will be described in more detail with reference to Examples. In addition, each characteristic value in an Example was obtained by the following method.

A. Single-thread fiber diameter Using the double raschel knitted fabric obtained in the example as a sample, the fibers constituting each of the front surface structure, back surface structure, and knotted structure are extracted from the sample, and each fiber is vapor-deposited with a platinum-palladium alloy. Using a Hitachi scanning electron microscope (SEM) S-4000, a cross section perpendicular to the fiber axis, that is, a fiber cross section was observed, and a micrograph of the fiber cross section was taken. The shooting magnification was 3000 times. Ten single yarns were randomly extracted from the obtained photographs, the fiber diameters of all the extracted single yarns were measured using image processing software (WINROOF manufactured by Mitani Shoji), and the average value was the single yarn fiber diameter. It was set to (μm). Since the fiber cross section is not always a perfect circle, the diameter of the circumscribed circle of the fiber cross section is used as the single yarn fiber diameter when it is not a perfect circle.

B. Width La of convex body of double raschel knitted fabric, width Lb of back surface structure of double raschel knitted fabric, length and thickness Da of convex body
Using the double raschel knitted fabric obtained in the examples as a sample, the widths La, Lb and the length of the convex body were measured using a caliper without wrinkles or slack in the knitted fabric. The thickness Da was measured at a load of 0.7 kPa for knitting according to the thickness measuring method described in JIS L1096. As for the width La, Lb and length measurement points, 10 points were measured per sample at intervals that equally divide the length in the warp direction of the knitted fabric, and the average values were the width (mm) and length (mm). As the thickness (mm), the width La was rounded to the nearest digit, and the width Lb, the length of the convex body, and the thickness were calculated by rounding off the first digit. The fact that the width La does not change substantially means that the maximum width and the minimum width of the 10 points measured based on the average value of the width La are both within ± 10% of the average value, and the absolute value thereof. The larger value was used as the variation and calculated in%.

C. Distance Lc, Length and Depth of Two Convex bodies of Double Russell Knitted Fabric Using the double Russell knitted fabric obtained in the Examples as a sample, using a caliper, the knitted fabric is adjacent without wrinkles or slack. The width Lc of the two matching convex bodies starts from the point where the fibers A constituting the middle layer come into contact with the structure of the surface formed of the fibers B and connected in a sheet shape, to the similar contact points of the adjacent convex bodies. The shortest distance was measured. When a knitted fabric having only one convex body was used, the shortest distance between the grounding points of two adjacent convex bodies was measured after laying on the garment. The measurement points were calculated by measuring 10 points per sample at intervals that equally divide the length of the knitted fabric in the warp direction, and rounding off one decimal place with the average value as the width Lc (mm). In addition, calipers were used to measure the longitudinal length and depth of the grooves formed between the two convex bodies of the double raschel knitted fabric. The measurement points are the intervals at which the lateral length of the knitted fabric is equally divided when measuring the length of the knitted fabric, and the length of the knitted fabric in the warp direction is equally divided when measuring the depth. Ten points were measured for each sample at intervals, and the average value was calculated by rounding off one digit of the decimal point with the width (mm) and depth (mm).

D. Air permeability The air permeability was calculated according to JIS L 1096 (2010) (textile and knitted fabric test method) 8.26.1 (method A) using the fabric obtained in the examples as a sample. The measurement was performed 5 times per sample, and the average value was taken as the air permeability (cm ³ / cm ² · s).

Next, regarding the situation inside the clothes after sitting in a chair for 1 hour and resting in a room with a temperature of 30 ° C and a humidity of 90% RH, assuming an indoor environment in the summer when air conditioning is not effective, "a feeling of heat and stuffiness". 5 points for "no feeling of heat", 4 points for "almost no feeling of heat and stuffiness", 3 points for "feeling a little feeling of heat and / or stuffiness", "feeling of heat and / or stuffiness""Ifeel" is 2 points, "I feel a strong feeling of heat and / or stuffiness" is 1 point, and the average score given by each of the 20 subjects is rounded off to calculate up to one decimal place, and the average score is A score of 3.0 or higher was passed.

F. Feeling of wearing As for the feeling of wearing, 20 subjects were asked to wear the clothes prepared according to the examples, and 5 points were given that "the skin feels extremely good and there is no discomfort due to wearing", and "the skin feels good". 4 points for "almost no discomfort due to wearing", 3 points for "slightly poor skin contact and / or slight discomfort due to wearing", 2 points for "poor skin contact and / or discomfort due to wearing" One point was "extremely poor skin contact and / or strong discomfort due to wearing", and the average score given by each of the 20 subjects was rounded off to calculate up to one decimal place, and the average score was 3. A score of 0.0 or higher was considered a pass.

G. Designability Regarding the designability, the mannequin was made to wear the clothes prepared according to the examples, and 20 subjects evaluated the appearance. 5 points, "There is no discomfort in appearance or swelling of clothes, and it can be worn in the office or at home without problems", "There is almost no discomfort in appearance or swelling of clothes, and there is resistance to wearing in the office or at home. 4 points for "No", 3 points for "There is a slight discomfort in appearance and / or swelling of clothes, but it can be worn in the office or at home", 3 points for "Discomfort in appearance and / or swelling of clothes, so the office 2 points for "I have a strong resistance to wearing at home or at home" and 1 point for "I have a strong resistance to wearing at office or at home because of the discomfort of appearance and / or the swelling of clothes", and each of the 20 subjects The average score of the added points was rounded off to calculate up to one digit of the decimal point, and an average score of 3.0 points or more was regarded as acceptable.

The short-sleeved polo shirt of Example 4 was excellent in design. In addition, the feeling of heat and stuffiness was suppressed by the effect of the ventilation flow path inside the clothes formed by the body and the groove-shaped depressions of the double raschel knitted fabric, and the feeling of wearing was also excellent.

Comparative Example 1
In a double raschel knitting machine, the front surface structure and the back surface structure are knitted using false twisted yarn of 167 dtex-48f of polyester fiber (single yarn fiber diameter 22 μm), and monofilament of 440 dtex of polyester fiber (single yarn fiber diameter 250 μm). A reed structure for knitting a middle layer consisting of a knotted structure and forming a wide portion and a narrow portion having a thickness of 10 mm and a width of a convex body changing between 3.0 and 8.0 mm. I made a double raschel knitted fabric in. It has a narrow groove portion and a thick groove portion in which the width of the back surface structure is 120 mm and the width of adjacent convex bodies varies between 5 and 10 mm, and there are 12 convex bodies and a groove shape formed between the convex bodies. A double raschel knitted fabric having 11 dents was prepared. Then, the obtained double raschel knitted fabric was cut so that the length in the warp direction was 270 mm.

Subsequently, using a false twisted yarn of 84 dtex-72f of polyester fiber, a Kanoko structure was obtained with a single circular knitting machine, and then a predetermined dyeing process was performed to prepare a fabric having a basis weight of 200 g, which was further sewn to a length of 65 cm. I made a short-sleeved polo shirt. After that, at a position 250 to 280 mm above the hem on the back body, a hole of 30 mm in length × 100 mm in width was made so as to be in the center position on the left and right, and a polyester mesh fabric created by warp knitting with a ventilation rate of 500 cc / cm ² / sec. Was attached to make it an intake port. In addition, at a position 30 to 60 mm below the collar of the back body, make a hole of 30 mm in length × 100 mm in width so that it is in the center position on the left and right, and attach a polyester mesh fabric with a ventilation rate of 500 cc / cm ² / sec to the exhaust port. And said.

Inside the back body of the obtained short-sleeved polo shirt, the surface tissue of the double raschel knitted fabric is in contact with the body side, that is, the convex body is in contact with the skin side, and the vertical direction of the garment and the warp direction of the double raschel knitted fabric are different. Installed to match. The double raschel knitted fabric was iron-bonded using an interlining so that the lower end of the double raschel knitted fabric was 220 mm above the hem of the back body and was centered on the left and right. At this time, the bonding was performed with great care so that the height of the convex body did not change. At this time, it was confirmed that the upper end position of the intake port of the short-sleeved polo shirt and the lower end position of the double raschel coincide with each other, and the double raschel arrangement does not interfere with the intake.

A wearing test was carried out using the short-sleeved polo shirt prepared above. The obtained evaluation results are shown in Table 1. The short-sleeved polo shirt of Comparative Example 1 was excellent in design and wearing feeling. However, since the groove-shaped depressions of the double raschel knitted fabric have fine grooves and thick grooves, the effect of the ventilation flow path inside the garment formed by the groove-shaped depressions of the body and the double raschel knitted fabric is remarkable. It decreased, and the suppression of heat and stuffiness did not reach the passing level.

Comparative Example 2
In Comparative Example 1, two blower units were attached to the short-sleeved polo shirt so that the upper end of the blower unit touched the lower end of the double raschel knitted fabric (so that the blower port blown from the blower unit touched), and a power cable was used. The power supply unit and all the blower units were connected. A centrifugal fan having an outer diameter of 30 mm and a thickness of 5 mm was used as the blower unit. Except for the above, a short-sleeved polo shirt was produced in the same manner as in Comparative Example 1, and it was confirmed that the intake port of the polo shirt and the intake port of the blower unit were in the optimum arrangement so as to overlap.

Using the obtained short-sleeved polo shirt, the total flow rate of the outside air taken in from each ventilation unit was set to 0.7 L / sec, and the air was blown upward in a direction substantially parallel to the body to carry out a wearing test. The obtained evaluation results are shown in Table 1. The short-sleeved polo shirt of Comparative Example 2 was excellent in design and wearing feeling. However, since the groove-shaped depressions of the double raschel knitted fabric have fine grooves and thick grooves, the effect of the ventilation flow path inside the garment formed by the groove-shaped depressions of the body and the double raschel knitted fabric is reduced. Despite the air blown from the blower unit, the suppression of heat and stuffiness did not reach the passing level.

Comparative Example 3
In Example 1, a double raschel knitted fabric was prepared under the same conditions and the same method except that 70 dtex polyester monofilament (single yarn fiber diameter 100 μm) was used for the fiber A. At this time, in order to make the convex body of the double raschel knitted fabric stand upright and improve the shape retention, the convex body is supported upright so as not to tilt in the left-right direction (the weft direction of the knitted fabric) at 180 ° C. Although the dry heat was set for 1 minute, the thickness of the middle layer could not be secured because the fiber A was thin, and the convex body did not recover and became 4 mm in thickness. Other than that, a short-sleeved polo shirt was produced in the same manner as in Example 1.

Using the obtained short-sleeved polo shirt, the total flow rate of the outside air taken in from each ventilation unit was set to 0.7 L / sec, and the air was blown upward in a direction substantially parallel to the body to carry out a wearing test. The obtained evaluation results are shown in Table 1. The short-sleeved polo shirt of Comparative Example 3 was excellent in design and wearing feeling. However, since the single yarn fiber diameter of the monofilament is small, the thickness that can suppress the crushing of the double raschel knitted fabric and maintain the thickness of the double raschel knitted fabric is 4 mm. Therefore, the ventilation flow path inside the garment formed by the body and the groove-shaped depressions of the double raschel knitted fabric became narrow, and the suppression of the feeling of heat and stuffiness did not reach the acceptable level.

Comparative Example 4
In the second embodiment, the double raschel knitted fabric is not attached to the short sleeve polo shirt, the blower unit is attached to the same position as in the second embodiment inside the short sleeve polo shirt, and the power supply unit and all the blower units are connected by using the power cable. A short-sleeved polo shirt was produced in the same manner as in Example 2 except for the above. It was confirmed that the intake port of the polo shirt and the intake port of the blower unit are in the optimum arrangement where they overlap.

Using the obtained short-sleeved polo shirt, the total flow rate of the outside air taken in from each ventilation unit was set to 0.7 L / sec, and the air was blown upward in a direction substantially parallel to the body to carry out a wearing test. The obtained evaluation results are shown in Table 1. The short-sleeved polo shirt of Comparative Example 4 was excellent in design. However, since there is no ventilation flow path inside the garment formed by the body and the groove-shaped depression of the double raschel knitted fabric, the suppression of the feeling of heat and stuffiness did not reach the acceptable level. In addition, since the blower unit touches the body inside the clothes, there is a feeling of strangeness when wearing the clothes, and the feeling of wearing is inferior.

Since the double raschel knitted fabric of the present invention can form a ventilation flow path inside the garment by laying it inside the garment, the hot air inside the garment is efficiently discharged to the outside of the garment through the ventilation flow path, and the garment The internal environment can be kept comfortable, and it is also excellent in wearing comfort and design. Therefore, it can be suitably used in a high temperature and / or high humidity environment, and in various wearing scenes such as offices and homes where comfort is required.
