Silk is a kind of textile, which is woven with silk or synthetic fiber, artificial fiber, short silk, etc., and is a general term for fabrics purely woven or interwoven with silk or artificial silk. In ancient times, silk was a textile woven from silk (mainly mulberry silk, but also a small amount of tussah silk and cassava silk). Due to the expansion of textile raw materials in modern times, all textiles made of artificial or natural filament fibers can be called silk in a broad sense. The silk woven from pure mulberry silk is also called "real silk".

In fact, on the market, artificial silk is not expensive, the most expensive is "real silk", commonly known as real silk. Artificial silk in the market is like "Tencel" and "ice silk". With the development of material science, materials such as Tencel and ice silk are already very close to real silk in some basic properties. Easy to wrinkle and breathable. And industrial production has greatly reduced the cost, so now many cheap silk products use this "artificial silk" as the fabric, and the cost performance is still extremely high for daily use.

  Then let's take a look at why "real silk" is so expensive.

  Real silk is different from artificial silk, which is a chemical product. Real silk is the kind of pure natural silk woven that everyone has known since childhood. Compared with artificial silk, the production process of real silk is much more complicated, requiring multiple processes such as sericulture, silk reeling, and weaving. And the cycle is long, among which really good silk requires silk companies to control the quality of the whole process from the silkworm raising, so the top silk companies are half of the agricultural enterprises, after all, raising silkworms is a big agricultural project, and even need supporting A large mulberry orchard.

  Although modern technology is constantly optimizing every production link, raising silkworm babies and raising mulberry trees is a real investment, and the responsible brand must also make great efforts in selecting upstream suppliers carefully select them. In addition, in the follow-up process of silk, such as the layer-by-layer laying of silk quilts and positioning and stitching of silk fabrics, highly skilled manual labor is required. For the time being, some of them cannot be perfectly replaced by machines, so the overall output of silk products will not be too high. In this way, the price of real silk will go up when the cost and output are combined.

  What are the advantages of silk?

This question has to be divided into two, one is the advantages of silk in a broad sense, and the other is the advantages of real silk.

In a broad sense, the advantages of silk (both man-made and natural) are mainly reflected in the visual and tactile aspects. Visually, the silk texture fabric will show a delicate metallic texture under the light, which is very shiny. Anyway, it looks very atmospheric when laid on the bed. , It also looks like very rich, give a chestnut:

In terms of touch, it is the silky smoothness in the chocolate advertisement of Moufu, and it has a cool feeling, and the friction and stimulation coefficient with the human body is small.

Man-made fibers such as Tencel can make some of the excellent characteristics of silk available to more consumers at a lower price. It is a cost-effective choice for a quality life.

  What are the irreplaceable advantages of natural silk (silk)?

  1. Silk is composed of protein fibers, which have good biocompatibility with the human body. In addition, the surface is smooth, and its frictional stimulation coefficient to the human body is the lowest among all kinds of fibers, only 7.4%. Long-term use is beneficial to the skin. Anti-aging and anti-wrinkle. At the same time, it contains 18 kinds of amino acids necessary for the human body, which are almost the same as those contained in human skin, so it is also known as the "second skin" of human beings, and it is the gospel for people with sensitive skin.
  2. Good moisture absorption and dehumidification. Silk protein fibers are rich in many hydrophilic groups such as amine groups (-CONH) and amino groups (-NH2), and because of their porosity, it is easy for water molecules to diffuse, so they can absorb or emit water in the air, and Stay hydrated. Under normal temperatures, it can help the skin retain a certain amount of moisture and not make the skin too dry; when worn in summer, it can quickly dissipate the sweat and heat from the human body.
  3. Silk also has good warmth retention. Its heat retention is due to its porous fiber structure. There are many extremely fine fibers in silk fiber, and these fine fibers are composed of even finer fibers. Therefore, more than 38% of the seemingly solid silk is actually hollow, and there is a lot of air in these gaps, which prevents the heat from dissipating and makes silk have good warmth retention.
  4. In addition, the thermal denaturation of real silk fibers is small and relatively heat-resistant. When heated to 100°C, only about 5-8% become brittle, while the thermal variability of most synthetic fibers is 4-5 times greater than that of real silk. The burning temperature of silk is 300-400°C, which is a flame-retardant fiber, while the burning temperature of synthetic fiber is 200-260°C, that is, flammable and fusible. Therefore, silk also has the function of flame retardancy, which is relatively safe.

  As mentioned above, as the only biological protein fiber used in home life, silk still has its unique features, but there is no perfect product in the world, and the disadvantages of real silk are also obvious, such as delicate, difficult to maintain, easy to wrinkle, etc. Do you want to buy it? Whether it is worth buying or not depends on the specific needs of each individual. For example, if the skin is prone to allergies, likes to sleep naked, or has requirements for skin care, even if you spend more money, you can still enjoy your life better.
