              Pure wool carpet refers to carpets made of wool as the main raw material. It is a high-grade product in carpets. It is generally used in high-end hotels, hotels, living rooms, reception rooms, villas, national venues and other high-end places.

              Introduction to pure wool carpet

              Pure wool carpet refers to carpets made of wool as the main raw material. It is a high-grade product in carpets. It is generally used in high-end hotels, hotels, living rooms, reception rooms, villas, national venues and other high-end places.

              The advantages of pure wool carpet are:

              1. Warm and soundproof without pollution. The fiber is warm, non-flammable and gorgeous in color, thick in texture, heat-insulating and silencing, durable, not easy to bond, and no pollution. And wool carpets can also reduce the formaldehyde content and carbon dioxide in the room.

              2. Humidity control, moisture resistance and electricity resistance. Wool is an animal fiber that is tubular and has a respiration effect. When there is a lot of moisture in the room, the wool can absorb moisture; when the room is dry, it can release water. This property not only allows the wool carpet to regulate the dry humidity in the room, prevents combustion, but also prevents electricity from being charged in the indoor air. The surface of the wool is scaly and also has a good moisture absorption effect.

              3. The best elasticity and long service life. Wool rugs are the best of the carpet, because of the natural hair quality, soft feet, wear resistance, long service life.

              The disadvantages of pure wool carpets are:
              The dust performance is strong, the cleaning is difficult, and it is easy to produce water stains; it is easy to breed bacteria and full insects, and the price is also high.

              The following methods can be used to select pure wool carpets:

              The first is to identify the material. The method is to take a few pieces of wool from the carpet and ignite it according to the burning condition and the odor emitted. Pure wool does not burn when it is burning. Smoke, blistering, and odor. The ash is mostly shiny and black. It is broken with a finger.

              The second is to check the quality of production. The surface of the carpet should not have excessive hair removal. The combination of the surface of the carpet and the underlay should be strong, and the weft and weft threads should be tight and should not have excessive stretchability. During the transfer and storage of the back of the carpet, attention should be paid to the phenomenon of moisture and mildew. If it is a patterned rug, check whether the edge is open or broken. When checking its density and elasticity, it can be pressed on the carpet with the thumb. After pressing it, it can be quickly restored to its original shape, indicating that the density and elasticity of the woven fabric are good. It is also possible to bend the carpet, the more difficult it is to see the bottom mat, The plush is denser and more durable.

              In addition, we can use the following two methods to identify quality problems:

              Sensory identification. This method does not require any equipment and other items, and is based on the experience of long-term work and its own intuitive ability, based on the feel of the wool carpet and the suede. Acrylic rugs, commonly known as fake wool rugs, because acrylic fibers have unique characteristics similar to wool fibers, making it difficult to distinguish between wool rugs and acrylic rugs. However, as long as they are carefully observed and carefully compared, they still have differences. Intuitively, wool carpets are softer and more elastic than acrylic carpets, and they are softer in color and color.

               Combustion method. A few wool yarns are taken out from the wool carpet and identified by the burning method. When the wool is burned, it will blister while smoking, accompanied by the smell of burning hair, more ash, and shiny black brittle blocks. shape. When the acrylic fiber is burned, it melts while burning slowly. The flame is white, bright and powerful, with a slight black smoke and a scent of fish. The burnt ash is white and spherical, brittle and brittle. When the nylon burns, it melts while slowly burning, and it emits white smoke. The flame is small and has a blue color and a scent of celery. The gray is a light brown lumpy and is not easily crushed.

              What is the difference between “100% wool carpet” and “pure wool carpet”?

              According to national regulations, 100% fiber content is called “pure sweater”. The worsted product is allowed to contain no more than 5% of non-wool fibers (such as acrylic, polyester, etc.). The woollen finished product is allowed to contain no more than 7% of non-wool fibers.

              The non-wool fiber content of the worsted product can be relaxed to 7%. The woollen finished product contains no more than 7% of non-wool fibers, but the total amount of the two must not exceed 7%.

              Worsted or roving products are marked as “pure wool” instead of “100% wool”. Only 100% finished products, trademarks or tags are marked with “100% wool”.
