What are the advantages and disadvantages of pure wool carpet? How to choose?

The advantages of pure wool carpet are: 1. Warm, sound-proof and pollution-free. The fiber is warm and non-combustible, colorful, thick in texture, heat and sound insulation, durable, not easy to bond and pollution-free. Moreover, wool carpet can also reduce indoor formaldehyde content and carbon dioxide. 2. Humidity, hygroscopicity, flame retardancy and resistance. Wool belongs to animal fiber, which is tubular and has the function of breathing. When there is much indoor moisture, wool can absorb moisture; When the room is dry, it can release water. This feature can not only make the wool carpet adjust the indoor dry humidity to prevent burning, but also prevent it from being charged in the indoor air. Wool has scales on its surface and good hygroscopicity. 3. Good elasticity and long service life. Wool carpet is the most elastic neutral carpet. Because it is natural wool, it has soft feet, wear resistance and long service life. The following methods can be used to choose pure wool carpet: First, identify the material. The method is to take some wool from the carpet and identify it according to the burning situation and smell. When pure wool burns, there is no flame, no smoke, no foaming and no smelly ash. Most of them are shiny black solids, which will be broken when a finger is pressed lightly. The second is to check the quality of production. There should be no excessive depilation on the carpet surface, the combination between the carpet surface and the backing should be firm, and the woven warp and weft should be tight, and there should be no excessive stretching. Pay attention to whether the back of the carpet is damp and moldy during transportation and storage. If it's a patterned carpet, check whether there is any seam or stubble on the sideline. When testing its density and elasticity, you can press it on the carpet with your thumb. If it can recover quickly after pressing, it means that the density and elasticity of woven velvet are better. You can also bend the carpet, and the harder it is, the less you can see the bottom mat, indicating that the plush is densely woven and durable.
