Ice silk feels cold when worn, but the material feels a little like polyester. So, what exactly is ice silk? Let’s take a look together
Is ice silk polyester fiber?
Ice silk has the composition of polyester fiber
On the Internet, it is said that ice silk is chemical fiber, and some say viscose fiber. , in fact, are not entirely correct. Ice silk should be intertwined with polyester fiber and cellulose fiber. Cellulose fiber has good moisture absorption and breathability properties, with a moisture regain rate of 12 to 15%, while the moisture regain rate of cotton is only 8%. Good moisture absorption and breathability make it possible to quickly wick away sweat on hot nights, keeping you cool and comfortable while you sleep.

Principle of ice silk
Icy silk generally refers to chemical fibers, such as polyester and nylon. There are two reasons for its special functions: the special fiber structure and the addition of special raw material. Let’s talk about it in detail below:
Chemical fibers are all by-products of petroleum. Before they are made into filaments, they are like rock sugar. The ingredients are organic macromolecules. The process of making filaments is like making steel bars. The raw materials are mixed together. Melt, and then pass through a space many times thinner than the eye of a needle at high speed. When it comes out, it solidifies instantly and a single thread is formed. Then many threads are mixed together to form a yarn that can be used in textiles, such as 150D/144F polyester. , refers to a 150D thick yarn, which contains 144 polyester fibers. How thick is 150D? You can’t find it if you take apart the T-shirt you wear in summer.
Because it solidifies when exposed to cold, the cross-section of the fiber can be chosen arbitrarily. The cross-section of commonly used ordinary polyester is a circle, and the fabric is very tight, so the breathability is not good, but it is cold. The cross-section of the silk is cross-shaped. After it is woven into fabric, the fabric has a large internal space, and the air can easily circulate. The evaporation of sweat is naturally much faster than ordinary polyester. In terms of feeling, it is cold.
In addition to this, Bingliangsi will also add some special ingredients. For example, the Hualien Lantian Jade in the picture below has its differences in different raw materials, but more importantly, its form. The Lantian Jade will be ground into very fine powder and added to it, which can increase the conductivity of the fiber to heat. These powders Attached to the surface of the fiber, the sweat carries body heat and is conducted to the outer layer of the fabric through air convection, where it evaporates and dissipates heat. Together, it achieves a cool feeling. However, this powder is time-sensitive, and repeated washing will reduce its effect.

What is ice silk?
Ice silk is actually a kind of rayon, which is obtained by optimizing the raw materials of viscose fiber, viscose filament and polyurethane fiber. Therefore, ice silk is more pure in nature than cotton fiber and wood fiber. The cellulose content of ice silk is more than 99.5%. Cotton fiber and wood fiber account for 95–97%, ice silk’s fat and wax account for 0.2–0.3%, cotton fiber accounts for 0.5–0.6%, ice silk contains no chlorine-containing substances. Chlorine-containing substances in cotton fiber account for 1-1.1%. Ice silk does not contain pectin and polysaccharide.

Advantages of ice silk
The moisture content of ice silk is suitable for the physiological requirements of human skin, and it has the characteristics of smooth, cool, breathable, antistatic, and colorful. The ice silk mat product has the characteristics of coolness and smoothness, strong breathability, and firm texture. The mat can be folded and placed for easy storage, which greatly saves storage space. Modern processes such as cutting, twisting, warping, and weaving enhance the comfort, coolness, smoothness, and wear resistance of the product. The core plant on the front is vine weft (Asian grass or rattan), which has been waterproofed for easy maintenance and collection
