How much do you know about the material of socks?
Socks are made of all kinds of fibers. Common socks are made of cotton, combed cotton, mercerized cotton, spandex, lycra, nylon, nylon, acrylic, polypropylene, polyester, viscose, tencel, bamboo, model, linen and Puma cotton. However, it is very complicated to know the characteristics of each kind of fiber and the proportion of the fibers in order to have the most comfortable foot feeling. Understanding them can help you choose the right socks.
Usually we prefer to wear pure cotton socks, but is pure cotton 100% cotton?
In fact, there are no 100% cotton socks, if the composition of a pair of socks is 100% cotton, then the pair of socks is completely inelastic, socks have to be woven very wide to fit in, you can imagine how heelless these socks are. 100% cotton socks shrinkage rate is particularly high, not strong, wearable. 100% cotton socks are not called cotton socks, but cotton. Usually, socks with more than 75% cotton content can be called "cotton socks", and socks with 85% cotton content are very high-end cotton socks. Other functional fibers need to be added to maintain the elasticity, fastness and comfort of socks. Polyester, spandex and nylon are very common functional fibers.
[Socks Material--Combed Cotton]
Combed cotton is a long, neat cotton fibre left by a machine called comber after removing shorter fibers from ordinary cotton fibers. Because of the removal of short cotton fibers and other fibre impurities, the yarn spun with combed cotton is more delicate and the handle of the finished product is smoother and comfortable.
[Socks Material--Mercerized Cotton]
Mercerized cotton is a kind of cotton fiber which is treated by mercerizing ordinary cotton fibers in concentrated alkali solution. This kind of cotton fiber has better glossiness (shiny, silk-like composition), smoother handle and less wrinkle than ordinary cotton fibers without any change in other physical properties. Mercerized cotton is often seen in thin socks in summer.
Spandex is commonly known as elastic fiber. It has high elasticity and strong flexibility. Its stretching length can reach 5-7 times of the original fiber. The textile products with spandex can always keep the original outline. The composition of socks must contain spandex in order to make socks elastic and retractable, easy to wear, and make socks more foot-tight, like swimming suits, can be wrapped tightly around the feet, without slipping.
[Socks Material--Leica | LYCRA]
Now the well-known Lycra is actually a kind of spandex fiber, but it is a trademark registered by DuPont Company of the United States. Just like the apples we eat everyday, "Red Fuji" is an apple, "Guoguang" is an apple, "Marshal Huang" is also an apple, which is a name of apple. The same goes for Lycra. In 1958, DuPont invented and produced a unique artificial elastic fiber, which can be mixed with various artificial and natural fibers and processed into various types of ready-made clothes. Its extraordinary stretching and restoring properties greatly enhance the color of all fabrics. DuPont has registered a special name for it, LYCRA, which is translated into Leica in China, also known as Rack. Like nylon of that year, it belonged to DuPont's invention and registered its own trademark.
[Socks Material--Nylon | Jinlun/Polyamide]
Polyamide is a synthetic fiber with Chinese characteristics. Its scientific name is Polyamide. The first synthetic fiber factory in China is Jinzhou Chemical Fiber Factory, so it is named "nylon". The properties of nylon and nylon are similar. They are strong and wear-resistant. They are the most wear-resistant and strong synthetic fibers. Light weight and good elasticity, adding nylon in socks can maintain high strength elasticity.
Nylon is the first synthetic fiber in the world developed by Carothers and a research team under its leadership. The appearance of nylon has brought a new look to textiles. The synthesis of nylon is a major breakthrough in synthetic fiber industry, and it is also an important milestone in polymer chemistry.
Acrylic fiber is acrylonitrile in our country, it is soft, light, warm, known as "artificial wool". It weighs more than 10% lighter than wool, but its strength is more than twice as strong. Acrylic fibers are not mouldy or moth-eaten, and are twice as resistant to sunlight as wool and 10 times as resistant as cotton. As early as the 1970s and 1980s, what Southern women called "bulging wool" was acrylic fibers. The wool made of acrylic fibers was very light and soft, so it was loved by people at that time. However, acrylic fabrics have a very big disadvantage, which is easy to pill and poor wear resistance. Acrylic fibers are added to the fabrics to enjoy its light, soft and warm properties.
Polypropylene fiber is a name with Chinese characteristics. In fact, it should be called polypropylene fiber. Because there is a word of polypropylene in the name, and in the past it was called XX fiber, so it was called polypropylene fiber. The greatest advantage of polypropylene fiber is its light texture, but its hygroscopicity is very weak, almost no hygroscopicity, so the moisture regain is close to zero. However, its wicking effect is quite strong, and it can transfer water vapor through the fibers in the fabric, which also means that socks containing polypropylene fiber have very strong sweating function. Because of the strength of polypropylene fiber
