Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a novel underwear, particularly an underwear that can be comfortably worn even when sweating due to exercise.

When exercising, conventionally, people would layer wool or other clothing over cotton or wool underwear, and then wear outer clothing on top of that depending on the level of exercise. In this case, when the user sweats due to exercise, the underwear becomes wet with sweat and adheres closely to the body, making it sticky and extremely unpleasant. It is a common experience that when you stop exercising, especially during the winter season, you feel extremely cold due to sweat absorbed by your underwear.

This is particularly noticeable when exercising in winter when the outside air is low, such as skiing or mountain climbing.

The present inventors conducted research from the viewpoint of consumer science to improve the phenomenon that is experienced on a daily basis due to sweating due to exercise.

In a room maintained at 11 and 20G and a relative humidity of 65 degrees, participants wore various types of underwear and rode a stationary bicycle as shown in Figure 1 to measure the feeling of wearing and changes in humidity on the skin surface due to sweating. . In FIG. 1, it is an iFi stationary bicycle, and when the panelist 2 pedals 5 times, the bicycle does not move and only the wheels 4 rotate. 5 is a thermohygrometer 1. 6 is a cord, at the tip of which a sensor 7 is attached as shown in FIG. 2. In FIG. 2, 8 is a human body, and 9ij indicates underwear.

If you wear wool layered clothes over cotton underwear and ski wear on top of that and pedal for 15 minutes, you will get 6 to 1
After 0 minutes, you can feel the plating between your skin and underwear, and after 11 to 15 minutes, your skin will become sticky with sweat, making it extremely uncomfortable. When I take a break from exercising, I feel chilly for about 20 minutes as my sweat cools down.

Traditionally, cotton was thought to be suitable for underwear because it has high sweat absorption properties, but when exercising, these underwear have high sweat absorption properties and high sweat retention properties, so they do not dry easily and are not suitable as underwear. It was found to be ineligible.

Therefore, similar measurements were performed using hydrophobic fibers such as acrylic and ester fibers, which were originally considered unsuitable for underwear, as underwear. In this case, on the contrary, since it does not absorb sweat, a layer of sweat and water vapor is formed between the underwear and the skin as soon as the sweat comes out, resulting in the phenomenon of murel, which is also unsuitable.

Next, we changed the fin session, using cotton as the undergarment, and examined layered clothing in order to quickly dissipate the sweat absorbed by the cotton, using fibers from each juvenile in addition to wool. As a result, a layered garment using 50% hydrophobic fiber and 150% cotton was relatively effective, but the object of the present invention was still not achieved.

Therefore, as a result of further research, the present inventors discovered that the parameter called water testing rate is closely related to the comfort of wearing when sweating due to exercise, and thus completed the present invention. Nine.

That is, the present invention is an underwear made of hydrophobic synthetic fibers and having a water test rate of 60 or more.

5 The underwear of the present invention has a water retention rate of 501 when worn as a single layer.
The effect is even more pronounced when worn under clothing of 6 or higher.

The water transport vehicle and water storage vehicle of the present invention are measured by the following method.

As shown in Figure 5, IQC/
Water droplets 11 were attached at a rate of 100 cd, and sample 12
Overlap. Layer filter paper 13 (manufactured by Toyo Roshi Co., Ltd., Qualitative P paper size 1 (for -setting)) on top of the K layer, and 59/CH
Apply a load of I. Furthermore, at this time.

Sample the sample so that the size of the sample and the filter paper are the same. After leaving it in this state for 60 minutes, sample 12 and V paper 1
Measure the weight of the absorbed water in step 3, and calculate the water detection rate and water retention rate using the following formula.

The hydrophobic fibers of the present invention include semi-synthetic fibers such as triacetate fibers, polyamide-based, polyester-based, polyacrylic-based, and polypropylene-based synthetic fibers. For underwear with a water test rate of 60 vomit or higher.

This cannot be achieved with ordinary fibers; knitted fabrics made of thin yarns with single yarns of 0.5 denier or less, knitted fabrics made of yarns with L-shaped or V-shaped cross-sections, and porous yarns. Underwear made of a structured knitted fabric or the like is used. -The fabric weight is 50
~30097 m'' is preferred.

The water test rate is based on the yarn count, denier, and texture of the knitted fabric.

Since it varies depending on the type, it is preferable to set it to an appropriate value experimentally.

Layered clothing worn over underwear is cotton or rayon.

It is preferable to use a knitted fabric made of wool or the like with a basis weight of 100 to 500 f/m. The layered structure is preferably a mesh-like knitted fabric. In addition to the above-mentioned materials, one-wheel waterwheel,
As long as the water retention rate satisfies the above conditions, other materials may be used in conjunction with the cage.

The effects of the present invention will be specifically explained using the test results shown in Table 1.

Table 1 *1) i1 Product Name Tsurushi No. 64 single yarn *2) No. 40 yarn *5) Product Name Cashmilon No. 72 single yarn Mine Lissmooth, long-sleeved high neck shirt Layering is 50% acrylic fiber and cupra rayon 50-
A mesh knitted fabric consisting of 52-needle single yarn of 80 mm and 20 mm of 40-denier long stell fiber was used. Wearing snowwear as outer clothing, using the test apparatus shown in Figure 1, rest for 5 minutes after wearing, then pedal a stationary bicycle for 15 minutes (energy constant approximately 10 u Kcal), 4
It was silent for 0 minutes (energy consuming 50 Kel).

Figure 4 shows the change in humidity between the skin and underwear over time during exercise.

The feeling of wearing is as shown in Table 2.

As described above, compared to Comparative Example B using the present invention Ai and hydrophilic cotton underwear, the water transfusion rate is higher even though the values determined by the Pyrex method are similar. In addition, compared to Comparative Example C using normal hydrophobic fiber underwear, the Virex method has a higher R (II) and water transfusion rate.The difference is clearly observed in Figure 4 and in the feeling of wearing. .

The effects of the present invention are further improved by wearing layered clothing with a water retention rate of 50 cm or more over underwear.As described above,
Compared to conventional underwear, the underwear of the present invention causes less humidity increase between the skin and the skin surface when worn and exercised, and is less likely to become sticky with sweat. After you stop exercising, the humidity decreases quickly, and you don't feel as sticky or cold. Therefore, it is suitable for exercising in winter environments with low outside air.

Hereinafter, the present invention will be specifically explained with reference to Examples.
