In current day-to-day life and sports, socks are not always given due attention. Socks have always been used as a foil to shoes. People have long believed that they mainly rely on shoes to protect their feet. However, it is necessary to pay attention to socks and feet Closely, if the socks are not properly selected, the shoes will cause direct damage to the feet.
Here are some common materials for socks:
Cotton is a traditional natural fiber, and it is also a highly comfortable textile material. It is still used in large quantities today. However, for the requirements of sports, especially outdoor sports, the performance of cotton itself has great limitations. The moisture absorption of cotton fiber is very good, and the moisture absorption rate is very fast, but it is not enough to get rid of moisture. After the cotton fiber is wet, it will be very slow. Therefore, if you do not have a good supply of logistics, try not to wear pure cotton socks in outdoor activities, especially for multi-day activities in the rainy summer, socks after soaking, it will be very dangerous.
Wool is also a kind of traditional natural fiber. It is known for its good warmth. However, ordinary wool is not suitable for socks. It must be made of high-quality wool, such as Australia's MERINO WOOL. ), NEW WOOL (new hair), etc., are good materials for underwear and socks. However, many people will find that the direct use of wool for personal clothing is rare, if any, and the price is relatively high, which is mainly determined by the structural characteristics of the wool itself. Under the microscope, you can see that there are many scales of wool fibers, arranged somewhat like bamboo shoots, and each scale has a keratinized tip at the top. This keratinized tip can easily cause adhesion between wool fibers. Sticking, at the same time, the horny tip makes the wool feel itchy when it is close, so if you use wool material to make intimate clothing like socks, you must remove the keratinized tip, this treatment The relatively high cost is one of the main reasons why the product is expensive. The wool itself is characterized by keeping warm, while its hygroscopicity and dehumidification are poor. After being blended or mixed with other fibers, it can be made into good winter warm socks.
Leica, spandex and elastics are all elastic materials. Leica is a registered trademark of the United States DuPont, in fact, is a type of spandex, so it is also known as Leica ammonia, but it is much better than ordinary spandex processing, its extension and recovery are very good, and not easy to aging, now Many outdoor brand socks use Leica for elastic materials. The rubber band is actually a rubber band. Of course, the socks used to make the socks are much thinner, and they are as thin as the yarn. They are woven into the socks during the manufacturing process. Elastic tends to age easily. After being corroded by sweat or through the winter cold, It is easy to lose the original extension and reversibility. For the more expensive socks for outdoor sporting professional sports socks, this feature makes it less economical. However, there is an elastic in Japan, and it is said that the durability is good, and it is still in the promotion stage.
For sports socks, especially professional sports socks that are very professional in outdoor sports, there must also be some special fibers added to highlight its professional functionality. Of these, COOLMAX is often used. COOLMAX is a patented fiber product of DuPont, which is also called four-pipe special polyester fiber. Ordinary fiber cross-sections are mostly solid round or elliptical, while COOLMAX fibers are hollow, cross-sectional ten sub-types, like four tubes that are juxtaposed. This structure increases the contact area between the fibers and the air, and also ensures a lot of voids between the fabrics. This ensures that the COOLMAX fiber has a strong hygroscopicity and moisture-removing properties, and incorporates COOLMAX fibers. The fabric is also very breathable. It should be noted that COOLMAX is a functional fiber that absorbs moisture, permeates, and breathes. It is not a warm fiber. It is simply a warm environment that keeps moisture out as dry as possible. THERMOLITE is a specialized thermal fiber, and THERMOLITE is also a patented fiber product of DuPont, which is the same as COOLMAX and is also a hollow fiber. According to reports, THERMOLITE was developed from the inspiration of polar bear fur structure. Its cross-section is circular, and the middle is empty, like a pipe, so as to increase the bulkiness of the fiber and achieve warmth. The effect of this principle is somewhat similar to that of down warmth. The thermal effect of THERMOLITE is very good. At the same time, it has good wicking effect. It is an ideal material for warm winter socks. (To explain this point, COOLMAX and THERMOLITE mainly use short fibers as material for socks. During the wearing process, pilling is inevitable. The tighter the structure of the socks, the less pilling will occur. Use COOLMAX. And THERMOLITE long fibers will not play, but feel socks are hard, not suitable for thick socks, made of thin single function liner socks are good.)
NYLON (nylon), some of the ingredients on the label also known as nylon, in the outdoor sports socks are specifically to strengthen the degree of strengthening, how to add nylon to extend the life of socks, not easy to damage.
Thermolite and coolmax are both moisture wicking fibers. Thermolite is also known as hollow thermal fiber. While sweating, it also emphasizes the function of keeping warm and the price is relatively expensive.
COOLMAX socks can be roughly divided into full coolmax socks, and coolmax/cotton blended socks: Socks are almost impossible to achieve 100% coolmax. When producing socks, you need to add spandex yarn. General coolmax socks content is 70%-85%. The sum of coolmax/cotton blend socks, coolmax and cotton accounts for about 70%-85%. If it is 50/50, coolmax accounts for 35-43%. In theory, the higher the coolmax content, the better the moisture wicking function.
In outdoor sports, some people think that as long as the socks are worn thick, at least two pairs of cotton socks can provide adequate protection for the feet. This is a certain reason, because the two pairs of socks can be better posted Attached to the foot, it weakens the friction between the foot and the sock and translates into friction between the sock and the shoe. However, in this way, another problem is overlooked. After a person walks long distances, the foot will expand by 7%--8%, and the two pairs of socks will be tightly tied to the entire foot, even above the ankle. Parts of the bag are also included, which results in poor blood circulation in the foot and may cause some foot problems. In winter or extremely cold areas, it will cause unnecessary frostbite.
So, what is a sock specifically designed for the feet? This is to understand the structure of socks:
First of all, there must be a pad, which is like a towel-like circle at the bottom of the sock, so it is also called a terry. The main function of terry is to increase the elasticity between the shoes and the feet. At the same time, the area of â€‹â€‹contact between the sock material and the air is also fully increased to make it have better moisture absorption and perspiration, and of course, the embodiment of moisture absorption and perspiration. Materials also have a great relationship. The height, density, and location of the terry should be different for different strength sports. In high altitude climbing or extremely long walks, there should be terry loops on the soles of the feet and feet, and the height and density of the terry are the highest, so that a better all-round play can be achieved. protection. In mid-to-long-distance walking and mid-to-low altitude mountaineering, socks are generally sufficient for the bottom of the sock. However, the height and density of the terry must be the highest. The height and density of terry can only be relatively low in walking on short-distance walking and logistic replenishment, such as special tourism and general tourism, but it must not be absent. It is the general physical exercise and socks still need to have terry.
Secondly, there must be a loop of elastic fixation in the sock's arch area so that the socks can be placed on the foot. In the past, there was often something like this: After walking for some distance, the socks on the feet all went to the front, or the socks turned sideways, and the soles of the feet went to the side of the feet, making the feet uncomfortable. This is because the sock and the foot are poorly adhered. Therefore, the elastic fixation of the ankle arches can avoid such occurrences as much as possible. When a person's sole touches the ground, normal contact with the ground is the least on the arch, and the arch has minimal friction when walking. At the same time, this is the middle part of the entire foot. It is most appropriate to add a fixed part to this part. Elastic fixation should not be too tight. If it is too tight, it will affect the blood circulation, and it cannot be too loose, otherwise it will not achieve a fixed effect. Socks will run on the same foot.
In addition, the toes and heels of socks must be thickened, the force of the heels is the greatest, and the toes are relatively weak, and special protection is necessary. The stitching between the sock tip and the sock sole must be flat and must not be ribbed. This place is the toe position on the foot. If the seam is ribbed, it is easy to scratch the foot.
The main part of the sock body is these, and then there is the part above the ankle. This part is basically exposed outside the shoes (boots), but there are certain special requirements.
Let's talk about the ankle first. This part is generally the location of the upper, plus a terry pad is still necessary, but because this part is the first place in the foot in contact with the air, the function of ventilation must be reflected in the structure, generally in the front of the ankle Where the contact with the tongue is made with a slightly sparse structure with a structure that is more than that of the loop structure, the elastic material is added at the same time. Because the inner layer of the tongue is mostly made of foam elastic material, it is softer and has less friction than the material in other parts of the shoe. Therefore, the corrugated structure selected in this position will not harm the foot. The ankle is also the place where the script body is most active. Adding elastic materials can ensure that the normal activities of the feet do not have too much sense of restraint.
Above the ankle, if it is worn in winter or in an extremely cold environment, socks should be high in waist, and some even go below the knee, and there must be a structure of terry, in other circumstances you can choose middle waist. However, whether it is mid-socks or high-waist socks, socks are after all part of the lower leg, so this part of the structure must use a better structure, elasticity should be moderate, fully designed for the thickness of the leg.
It's even better to add OUTLAST to the sock's material. Here's what OUTLAST looks like:
Outlast was actually a patented technology developed by the National Aeronautics and Space Administration (NASA) research project in the late 1970s and early 1980s. It was developed by the NASA for the moon landing program to create moon costumes for astronauts. Including gloves, socks, underwear, etc., and later developed into ordinary clothing, especially outdoor clothing, including ski wear, pants, sweaters and so on.
The key to Outlast's fiber technology is the use of microencapsulated, heat-sensitive phase change materials that have the ability to absorb, store, and release heat in the form of latent heat. In the temperature change, they can be transformed into each other in the solid state liquid, from which the effect of heat absorption and heat release can be achieved. The microcapsule thermosensitive phase change material in Outlast fiber is HYDROCARBON WAX which responds to the change of the external environment temperature on the skin and has a buffer effect on the temperature change.
The key to the human body's regulation of body temperature is the skin. When the wearer catches cold, the capillaries that carry the blood tube contract and expand through the skin, that is, the blood vessels contract and relax, so as to limit and increase the blood flow, thereby reducing or increasing the loss of heat. The phase change material of the microcapsules in the OutIast fiber is HYDROCARBON WAX, which can absorb and release heat according to the ambient temperature, respond to the change of the external environment temperature on the skin, and have a buffer effect on the temperature change. Therefore, it has a climate regulation function and forms a good microclimate between products such as body and clothing.
Feet are very sensitive to cold. Socks using OUTLAST can make you feel comfortable and not stretchy. Its characteristics are:
Helps you stay warm
Makes you feel warm and inflexible
More flexible, more fit
Temperature adjustment to meet your need for heat
The end of socks purchase
Finally, introduce the use of socks in different environments in outdoor sports. In different environments, socks with different structures and different materials should be used.
In extremely cold conditions such as snow-capped mountains and skiing, the selected socks must be made of warm fibers such as wool, and the structure should be higher and tighter, and the socks should be longer and even reach the knee. The material mixed with wool is preferably thermal fiber such as THERMOLITE. Others include NYLON and LYCRA. The selection of socks in the extreme zone is not as good as that of COOLMAX. In order to ensure the perspiration effect, a high level of COOLMAX can be added. Long fiber socks.
In winter field activities at low altitudes, such as camping and crossing (except for climbing), socks made of wool and COOLMAX can be used. The structure depends on the size of the activity and the length of time, and the number of long distances and days is longer. More activities, you can use a higher terry, denser mid-socks, if there is a special need for warmth, you can add a pair of thin THERMOLITE high fiber content of long socks.
In the spring, summer and autumn seasons, low-altitude activities can use COOLMAX plus cotton socks. The distance is long and the number of days is more. The content of COOLMAX should be more, so it is easier to take care of it. For short trips with a small number of days, you can use socks with a lower COOLMAX content. The structure is still determined by the intensity of the activity.
