Outdoor school what is sports underwear functional underwear

In outdoor sports, special tourism and mountaineering, most people's clothing likes to choose the onion-style wearing method, namely the inner layer of sweating underwear, underwear and socks, the middle layer of warm layer clothing and the outer layer of windproof waterproof and warm layer.

Here is a focus on underwear. Underwear mainly refers to close-fitting clothing, such as short underwear, long underwear, shirt, etc. In outdoor sports, the main role of underwear is to perspire, breathe and keep warm. Different environments and different seasons have different functions in these functions. The underwear in spring, summer and autumn is mainly sweating and ventilation, while the underwear in winter and early spring is mainly warm.

The main materials for making sports underwear are still mainly natural materials and artificial materials. Natural materials mainly refer to natural textile materials such as cotton, wool and silk. Although the current scientific and technical means, natural textile and apparel materials cannot meet the requirements. Sports have special functional requirements for clothing, but the uniqueness of natural materials still has an irreplaceable position: the warmth of wool fibers, the comfort of cotton fibers, and the warmth of down as a filling material.

Most of the commonly used underwear is made of cotton, because the comfort and water absorption of cotton are very good, and the raw materials are cheap, which is a very traditional natural textile material. However, for sports underwear, the biggest drawback of cotton is that it absorbs water quickly. The drying speed is very slow. People who wear cotton sports underwear usually have a lot of sweat on the surface of the body after the exercise is completely wet, resulting in wind and cold.

Another kind of wool underwear, this is mainly thermal underwear, heavier, not suitable for sports wear, at the same time, the water absorption of wool is not ideal, can not get the effect of sweating underwear. In addition, the comfort of wool is poor, and the feeling of close-fitting is not very good. After special treatment, the comfort of wool will be improved. This is the concept of sports wool and anti-shrinking wool.

Nowadays, the most commonly used outdoor and mountaineering sports are sports underwear with special-shaped polyester fiber as the main raw material, such as COOLMAX fiber of DuPont Company, also known as four-pipe shaped polyester fiber. Its structure is cross-shaped and cross-shaped. It ensures a larger contact area with air, which makes the water vapor more easily evaporate, thus ensuring the characteristics of moisture removal and sweat guiding, especially the clothing of 100% COOLMAX fiber, which has better moisture absorption and moisture wicking.

There are many kinds of special-shaped polyester fibers such as COOLMAX, such as COOLEVER in Korea, COOLPLUS in Taiwan, HOCOOLING, etc. In addition, there are many kinds in Japan and Europe, and their principles and functions are similar, but in some more detailed technologies. There are differences in the parameters.

However, it should be specially reminded that fibers such as COOLMAX are not equal to warm fibers, especially in underwear and underwear with COOLMAX fibers in the winter. This is because the fibers have a good sweat absorption and Dehumidification, try to keep the surface of the body dry, not let the body lose temperature due to moisture, there will be a feeling of warmth. Therefore, if you go to high altitude or extremely cold areas, you must choose sports underwear with warm tips on such fibers and other warm fibers.

THERMOLITE is another type of hollow polyester fiber. It is developed by mimicking the hair structure of cold polar animals. It has quite good warmth. However, in the pursuit of thinner underwear, its function does not seem to fully reflect its function. However, as a thicker fabric material such as socks and fleece, it is a pretty good thermal fiber.

Ordinary polyester/nylon (nylon) and other fibers are also commonly used in sports underwear. Many knitted garments or shirts now have the function of quick-drying. This is because the fibers are poorly hydrophilic and the fibers themselves are almost non-absorbent. Therefore, it will dry faster than cotton, resulting in a quick-drying surface phenomenon. However, as far as sports underwear itself is concerned, it should have active moisture absorption and moisture wicking.

Viscose fiber is a kind of underwear fiber that has been popular in recent years. Its main representative is modal and rayon. It is extracted from plant materials such as wood. Its comfort is quite good, but it is not in terms of special functional requirements. Very ideal.

Let me talk about the style and fabric structure of sports underwear:

Ordinary underwear styles require tightness and body, while sports underwear should be slightly looser. This is because the body will sweat when exercising, even if the sweating underwear material will not be able to expel the sweat in an instant, the underwear will be wet. And caused by the body's attachment, tight underwear will cause resistance to action at this time, so that the technical movements are deformed, so the style should be looser. The seams to be sewn in the underwear should be as small as possible, and the seams of the seams should preferably be flat, especially the seams of the shoulder seams. If the seam is too thick, it will increase the friction between the clothes and the body, affecting the comfort. In outdoor sports, it is often necessary to carry heavy loads, so the requirements for shoulder seams will be higher. When possible, it is best to use over-shoulder sleeves or shoulders.

Furthermore, the structure of the fabric or fabric. The principle of warmth of clothing is mostly the use of the principle of air layer, which is to form an air layer environment around the body. A typical example is down clothing. This principle is also applied to underwear, such as brushing in the inner layer of underwear fabric. A bit like fleece. There is also the use of the material itself to keep warm, such as wool / cotton. However, it seems that all the fiber materials suitable for underwear can not be fully adapted to the requirements of sports underwear, so the combination of different materials is an ideal choice, such as: cotton or wool mixed with COOLMAX shaped polyester fiber 100% cotton underwear, because of the poor moisture permeability of cotton, after wearing sweat, it will affect warmth and comfort, and even cause adverse consequences. The 100% COOLMAX shaped polyester underwear has good moisture wicking properties, but the warmth and comfort are not ideal, and the cost is high. 100% wool underwear has good warmth, but its other features limit its potential to become a professional sports underwear material.

Therefore, in the textile process, different fibers are mixed according to the characteristics and characteristics of various fibers. These methods mainly include: blending, blending, compounding, and the like.

Blending: In the process of spinning a fiber into a yarn, two or more fibers of different materials are spun in the same yarn.

Mixed weaving: It is a mixture of yarns of different materials in the process of textile fabrics, such as warp yarn is cotton, weft yarn is wool, which is a blended fabric of cotton and wool.

Composite: Two or more non-material textures, even fabrics of different structures, are synthesized together using physical or chemical methods. The most common example of outdoor sports is WINDSTOPER's fleece.

According to the different characteristics of the above several textile methods, according to the different requirements of wearing, choose a more suitable underwear fabric. Blended and blended, the structure between the fibers is tight. If you simply consider the problem of keeping warm, this form is good, but other functions will have limitations. Like cotton + COOLMAX, the structure between the fibers is too tight, which will directly affect the dehumidification of functional fibers. Therefore, it is still possible to have a little sweating or a slight movement. However, in the case of a large amount of exercise, more sweating, and a harsher environment, it is better to choose a composite fabric underwear, that is, the inner layer is a fiber material that is simply warm or comfortable, and the outer layer is a moisture absorbing row. Sweat, a fiber material with a good firmness, so as to ensure a single manifestation of the function of the inner layer of fiber, and to increase the functional area of ​​the functional fiber of the outer layer, but the problem is that if the warming effect is excessively emphasized, It is necessary to thicken the thickness of the inner fabric.

Special reminder: The choice of sports underwear is based on the individual's physical condition, the outer and middle layers of clothing and the environment in which they will face. The difference in physique determines the individual's ability to adapt to the environment.
