What is a pure wool carpet? The advantages and disadvantages of pure wool carpets and the scope of application, pure wool carpets are generally made of sheep wool. Our country's pure wool carpets are made from indigenous sheep wool. Sheep wool has long fibers, high tensile force, good elasticity, luster, thicker and strong fibers, and is the best quality material for weaving carpets in the world. At present, some manufacturers mix domestic sheep wool and imported wool fibers to make use of the characteristics of imported wool fibers, such as thin and bright, and have achieved good results.

The advantages of pure wool carpets are:
1. Warm and soundproof without pollution. The fiber is warm, non-flammable and colorful, thick texture, heat insulation and noise reduction, durable, not easy to bond, and no pollution. And wool carpets can also reduce indoor formaldehyde content and carbon dioxide.

2. Moisture-regulating, moisture-absorbing, flame-retardant and anti-electricity. Wool is an animal fiber, which is tubular and has a breathing effect. When the room is humid, wool can absorb water; when the room is dry, it can release water. This property not only enables wool carpets to adjust indoor dry humidity and prevent burning, but also prevents charging in indoor air. The surface of wool is scaly and it also has good moisture absorption.


3. The best flexibility and long service life. Wool carpet is the most elastic and neutral carpet. Because it is natural wool, it has soft foot feel, wear resistance and long service life.
The disadvantages of pure wool carpets are: strong dust-holding performance, difficult to clean, easy to produce water stains; easy to breed bacteria and insects, and the price is higher.

The following methods can be used to select pure wool carpets:
One is to identify materials. The method is to remove a few woolen threads from the carpet and identify them according to the burning situation and the smell. When pure hair burns, there is no flame, smoke, blisters, and smelly. The ashes are mostly shiny black solids, and they can be broken with a finger.
The second is to check production quality. The surface of the carpet should not have too much hair removal, the combination of the surface of the carpet and the underlay should be strong, the weaving of warp and weft should be tight, and there should be no excessive stretch. When the back of the carpet is transported and stored, pay attention to whether it is damp and moldy. If it is a patterned carpet, check whether the side line is open or broken. When checking its density and elasticity, you can press it on the carpet with your thumb, and it can quickly return to its original shape after pressing, indicating that the density and elasticity of the woven pile are better; you can also bend the carpet, the more difficult it is to see the bottom pad The plush is densely woven and more durable.

In addition, we can also use the following two methods to identify quality problems:
Sensory method. This method does not need to use any equipment or other items, and is identified based on the feel of the wool carpet and the suede through its long-term work experience and its own intuitive ability. Acrylic carpets, commonly known as fake wool carpets, because acrylic fiber materials have unique and excellent characteristics similar to wool fibers, it is difficult to distinguish wool carpets from acrylic carpets. However, as long as you carefully observe and compare carefully, there are still differences between them. Intuitively speaking, wool carpets are softer than acrylic carpets, are more elastic, have a large specificity, and are softer in color.

Combustion method. Pull out a few wool yarns from the wool carpet and use the burning method to identify them. When the wool burns, it will smoke while blistering. At the same time, it will have the smell of burning hair. There are many ash, shiny black brittle pieces. shape. When acrylic fiber burns, it melts while burning slowly. The flame is white, bright and powerful, with a little black smoke, and a fishy smell. After burning, the gray is white spherical, brittle and fragile. When the nylon burns, it melts while burning slowly, and it emits white smoke from time to time. The flame is small and blue, with the fragrance of celery. The gray is light brown and hard, not easy to crush.
