When I usually buy clothes, I usually see the word acrylic on the label. This is the name of a kind of fabric. So how much do you know about acrylic? For us, it is still important to understand what acrylic fiber is, so that we can at least master a little more knowledge. When it comes to what acrylic fiber is, of course we have to start from the beginning.
Acrylic fiber is actually our common name for polyacrylonitrile fiber. This material is widely used in clothes It is used, its properties are close to wool, and it has the reputation of “artificial wool”. In terms of performance, it has better elasticity and higher strength than wool. Its heat resistance is second only to polyester among synthetic fibers, and its light resistance is the best.
Now that we understand what acrylic fiber is, let’s take a look at the characteristics of acrylic fiber.
1. Acrylic fiber is called synthetic wool, and its elasticity and fluffiness are similar to natural wool. The warmth retention is not inferior to wool fabrics, and is even about 15% higher than similar wool fabrics.
2. Acrylic fabric has good dyeability, and its light resistance ranks first among various fiber fabrics. But its wear resistance is the worst among various synthetic fiber fabrics. Therefore, acrylic fabrics are suitable for outdoor clothing, swimwear and children’s clothing.
3. Acrylic fabric is not very hygroscopic and easily stained with dust. It will feel stuffy when worn, but its dimensional stability is maintained well.
4. Acrylic fabric has good heat resistance, ranking second after synthetic fibers, and is resistant to acids, oxidants and organic solvents, and is relatively sensitive to the action of alkali.
5. Acrylic fabric is lighter in weight than synthetic fabrics, second only to polypropylene, so it is a good lightweight clothing material and can be used to make mountaineering clothing, winter warm clothing, etc. .
In order to know more about what acrylic fiber is and if you want to distinguish acrylic fiber clothing, you can cut off a small piece of clothing and use the burning method to identify it. When acrylic fiber comes into contact with flame, it melts first and then burns slowly. A yellow flame appears with flash. It can continue to burn after leaving the flame, but at a slow speed. It emits a pungent smell when burned, somewhat like the smell of coal tar. After burning, the ash appears as irregular black hard lumps that are difficult to crush.
When using the same method to test polyester, when it comes into contact with the flame, it will first cause curling and melting, and then burn. While burning, the melt will drip down, and there will be a bright yellow flame. The heart is blue. When burning, there is black smoke at the top of the flame, and it stops burning when it leaves the flame. There is a slightly aromatic smell when the burning stops, and the ashes appear as black, glassy hard lumps that can be crushed with your fingers.
Now, we have an in-depth understanding of what acrylic is. Acrylic clothing is widely used in our lives. For example, the swimming suits we wear in summer and the mountaineering clothes worn by mountaineers are all made of this material. Acrylic clothing has its own advantages and characteristics, which we should make reasonable use of. </p
