Description

clothes

The present invention relates to clothing that can be suitably used in a high temperature and / or high humidity environment and various wearing scenes such as offices and homes where comfort is required.

As a measure against global warming, raising the set temperature of the air conditioner in the summer and lowering the set temperature of the air conditioner in the winter are one of the effective means for reducing carbon dioxide emissions. However, when the temperature of the air conditioner is changed, the comfort in the indoor space such as an office or a residence is lowered, and it becomes a problem that the stickiness due to sweating makes the person feel uncomfortable, especially in summer. Therefore, clothes for maintaining comfort by sending outside air into the clothes by using a fan have been proposed.

For example, in Patent Document 1, an air-conditioned clothes having an outer material and a lining provided with a fan for taking in outside air, forcibly causing an air flow in the space between the outer material and the lining. Air-conditioned clothes that can be used have been proposed. According to this proposal, the body can be effectively cooled by forcing an air flow in the space between the outer material and the lining.

As a result of diligent studies on clothes that can suppress the feeling of stuffiness and swelling in clothes and efficiently cool the body, the present inventors equip clothes made of fabric having a certain air permeability with a blower fan unit. In addition, by providing a flow path forming portion inside the garment to give directivity to the wind inside the garment, the garment can be suitably used in various wearing scenes such as offices and homes. I found it. Normally, when a highly ventilated garment is equipped with a blower fan unit, the swelling of the garment and the feeling of stuffiness inside the garment can be suppressed, but the wind escapes to the outside of the garment before the wind reaches the part of the body to be cooled. Therefore, it is difficult to obtain clothes having excellent wearing comfort. In response to this problem, as described above, in the present invention, a body to be cooled by providing a flow path forming portion inside the clothes to positively form a ventilation flow path for imparting directivity to the wind in the clothes. It became possible to guide the wind to the part of the body, and succeeded in dramatically improving the design and wearing comfort.

After that, at a position 250 to 280 mm above the hem on the back body, make a hole of 30 mm in length × 80 mm in width so that it is in the center position in the left-right direction, and attach a nylon mesh fabric with ^{a breathability of 550 cm 3} / cm ^{2 / s.} The intake port 4 was used. In addition, at a position 30 to 60 mm below the collar on 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 nylon mesh fabric with ^{a breathability of 550 cm 3} / cm ^{2 / s.} The exhaust port 5 was used.

As the flow path forming portion, the front surface structure and the back surface structure are knitted from 167 dtex-48f false twisted yarn of polyester fiber, and the binding structure of the middle layer is knitted from 440 dtex monofilament of polyester fiber, thickness T10 mm, length L300 mm. , A convex body is formed using a double raschel fabric with a width of W15 mm, and is attached to the inside of the back body of the short-sleeved polo shirt so that the vertical direction of the garment and the length direction of the convex body match. It was set to 1. As for the convex body, three convex bodies are parallel to each other at intervals of 50 mm in the width direction so that the lower end of the convex body coincides with the upper end of the intake port 4 and is symmetrical with the left and right center lines of the clothes. I installed it. Then, two blower fan units 2 having a centrifugal fan having an outer diameter of 30 mm and a thickness of 5 mm were attached to the inside of the clothes with an interval of 20 mm so that the outlets were directed toward the upper part of the clothes and overlapped with the intake ports 4.

After connecting an external power supply to the blower fan unit 2 of the obtained clothes with a cable, the blower flow rate ^{was set to 0.03 m 2} / min / piece, and a wearing test was carried out. The obtained evaluation results are shown in Table 1.

Table 3 shows the evaluation results of the obtained clothes.

[Examples 8 and 9]
As the fibers constituting the garment, 66dtex-72f false plying made of polyester having a ΔMR of 0.2% in Example 8 and 66dtex-72f made of hygroscopic polyester having a ΔMR of 3.1% in Example 9 were used. Clothes were obtained in the same manner as in Example 1 except that false twisted yarn was used. Table 4 shows the evaluation results of the obtained clothes.

Since the clothes obtained in Examples 1 to 9 have good results in all evaluations of comfort, wearing feeling, and design, they are suitably used in wearing scenes such as offices and homes. It became clothes.

On the other hand, the garment obtained in Comparative Example 1 is inferior in comfort because the feeling of heat and stuffiness in the garment cannot be suppressed due to the low air permeability of the fabric used, and the garment obtained in Comparative Example 2 Because of the high air permeability of the fabric used, the wind passed through the clothes and the wind did not reach the back, and the clothes were thin and transparent, so the clothes were inferior in comfort and design. The clothes obtained in Comparative Example 3 were inferior in comfort because the feeling of heat and stuffiness in the clothes could not be suppressed because the blower fan unit was not attached. Further, the clothes obtained in Comparative Example 4 are inferior in comfort because the body part to be cooled is not exposed to the wind because the flow path forming portion is not provided, and the feeling of heat and stuffiness in the clothes cannot be suppressed. It became. The clothes obtained in Comparative Example 5 have many convex portions but are not continuously formed, and the wind blown from the blower fan unit diffuses in the clothes, resulting in a feeling of heat and stuffiness in the clothes. The garment was inferior in comfort because it could not be suppressed.
