In outdoor sports, special tourism and mountaineering sports, most people's clothing matches like the selection of onion-style dressing methods, that is, the inner layer of wicking underwear, underwear and socks, the middle layer of warm clothing and the outer layer of waterproof thermal insulation layer.
Focus on underwear here. Underwear mainly refers to close-fitting clothing, such as underwear, long underwear, shirts, etc. In outdoor sports, the main function of underwear is perspiration, breathability, and thermal comfort. Different environments, different seasons, these features have different emphasis, spring, summer and autumn underwear is mainly perspiration, breathable, and winter and early spring underwear to keep warm.
The main materials used in the production of sports underwear are still natural and artificial. The natural materials mainly refer to natural textile materials such as cotton, wool, silk and hemp, although in terms of current scientific and technological means, natural textile and garment materials cannot satisfy the requirements. The special function requirements of sports for clothing, however, the uniqueness of natural materials still has an irreplaceable position: such as the warmth of wool fibers, the comfort of cotton fibers, and the warmth of downfills as filling materials.
Commonly used underwear is mostly made of cotton, because cotton's comfort, water absorption are very good, and raw materials are cheap, is a very traditional natural textile raw materials, but for sports underwear, the biggest drawback of cotton is that water is fast. The drying speed is very slow. After the people who are usually wearing cotton sports underwear, after the exercise, when the clothes are completely soaked, there is still a lot of sweat on the body surface, which leads to wind and cold.
Another 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, will not achieve the effect of underwear perspiration. In addition, the comfort of wool is poor, and the personal feeling is not very good. After special treatment, the comfort of wool will be improved. This is the appearance of sports wool, shrink-wool and other concepts.
Nowadays, the most commonly used outdoors and mountaineering sports are sports underwear with special polyester fiber as the main raw material. For example, DuPont’s COOLMAX fiber, also known as four-pipe special-shaped polyester fiber, is cross-sectionally cross-shaped. The type ensures a greater contact area with the air, making the water vapor easier to evaporate, thus ensuring the moisture-removing and sweat-conducting characteristics, especially the 100%COOLMAX fiber clothing, which has better moisture absorption and moisture absorption.
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 also many kinds in Japan and Europe. Their principles and functions are similar, but they are only in some more detailed technologies. There are differences in parameters.
However, to be particularly reminded that, COOLMAX a fiber does not mean that warm fiber, especially in the winter wearing a COOLMAX a fiber underwear, underwear will have a warm feeling, because the fiber has a good sweat absorption and Hygroscopicity, as far as possible to keep the body surface dry, do not lose the temperature due to moisture, there will be people feel warm. Therefore, if you go to high-altitude or extremely cold areas, be sure to choose this kind of fiber and other warm fiber mixed with warm reminding sports underwear.
THERMOLITE is another type of hollow polyester fiber that was developed by mimicking the hair structure of cold polar animals.
Has a very good warmth, but in the pursuit of thinner underwear today, its function does not seem to be fully reflected, but as a thick fabric material such as socks and fleece, it is quite good thermal fiber.
Ordinary polyester/nylon (nylon) and other fibers are chemical fibers that are often used in sports underwear. There are many knitted garments or shirts that are marked with quick-drying, because these fibers have poor hydrophilicity, and the fibers themselves are almost non-absorbent. , so do it faster than cotton, resulting in the surface phenomenon of quick-drying, but in terms of sports underwear itself, it should have active moisture absorption and hygroscopicity.
Viscose fiber is the underwear fiber that has become popular in recent years. The main representative is modal and rayon. It is extracted from wood and other plant materials. 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 the sports underwear should be slightly looser, because the body sweats during exercise, even if the underwear materials for re-perspiration can not be instantly exhaled, the underwear will be wet The result is that the tight underwear will cause the resistance of the action and make the technical movement deform, so the style should be loose. The sewing seam of the underwear should be as few as possible and the sewing of the seam should be the most. Good is flat, especially the seam of the shoulder seam. If the seam is too thick, it will increase the friction between the clothing and the body, affecting comfort. In outdoor sports, it is often necessary to walk with weight, so the seam on the shoulder The requirements will be higher. When possible, it is best to use a raglan sleeve or shoulder over shoulder.
Again, the fabric or fabric structure.
Most of the warmth principle of clothing is to use the air layer principle, which is to form an air layer environment around the body. A typical example is down clothing. This principle has also been applied to underwear, such as the inner layer of underwear fabrics, then brushing, effect A bit like fleece.
There is the use of the material itself to keep warm, such as wool, cotton, etc. However, it seems that all the fiber materials suitable for underwear can not be fully adapted to the requirements of sports underwear, so the use of different materials will become an ideal choice, such as :
Cotton or wool is mixed with special polyester fibers such as COOLMAX.
100% cotton underwear, due to poor moisture absorption of cotton, sweat after wearing, will affect the warmth and comfort, and even cause adverse consequences. And 100% of the COOLMAX type of special-shaped polyester fiber underwear moisture wicking Very good, but the warmth and comfort is not ideal, but at the same time the cost is high. 100% wool underwear has a good warmth, but its other features confined its potential to become a professional sports underwear material.
Therefore, in the textile process, different fibers are mixed and used according to the characteristics and characteristics of various fibers. These methods include: blending, blending, compounding, etc.
Blending: In the process of spinning a fiber, two or more fibers of different materials are spun in the same yarn.
Blending weaving: Blending yarns of different materials in the process of textile fabrics. For example, the warp yarns are cotton, the weft yarns are wool, and the cotton and wool blend fabrics.
Compounding: Combining two or more kinds of non-material textures, even fabrics with different structures, using physical or chemical methods. The most common example of outdoor sports is WINDSTOPER's fleece clothing.
According to the different characteristics of the above textile structure, according to the different requirements of wearing, choose more suitable underwear fabrics. Blended and mixed weaving, the structure between fibers is tight. If you simply consider the warmth, this form is good, but Other functions will be limited. For example, cotton + COOLMAX, the structure between the fibers is too tight, it will directly affect the moisture absorption of the functional fibers. Therefore, people who do not sweat very much or have relatively light activities can still However, in the case of a large amount of exercise, sweating, and a relatively hostile environment, it is better to choose a composite fabric underwear, that is, the inner layer is simply a warm or comfortable fiber material, and the outer layer is Moisture wicking and firm fiber materials with good firmness can not only ensure the single embodiment of the function of the inner layer fibers, but also increase the functional functional area of ​​the outer layer, but the problem is that if overheating is emphasized , then we must thicken the thickness of the inner fabric.
special reminder:
Choose sports underwear, or according to the individual's physique, the outer layer and the middle layer of clothing and will be facing the environment. The difference in physical fitness to determine the individual's environmental adaptability.
Sports underwear can only discharge the inner layer of sweat out of the inner layer. If the exhaust effect of the middle and outer layers is not good, it will cause the return of moisture. Do not be too superstitious about some fibers and fabrics with special functions. There is no need to have its mythology.
