Wool carpet is renewable, warm, luxurious, and durable, made from natural fibers. The unique fiber structure makes it strong, hard-wearing, and naturally stain resistant, and the insulation properties keep your home warm in winter and cool in summer.
Wool is a luxurious fiber in everyday use for carpets. Wool carpet flooring has excellent resilience, so it recovers well from crushing and retains its appearance. The wool fiber is naturally curly, which causes it to bounce back into shape when crushed.
HOW TO SELECT THE RIGHT WOOL CARPET
Length of the fiber: The longer the fiber in a carpet, the stronger it is. This means carpets with long wool fibers can tolerate even more wear than shorter ones and will last much longer. Wool is a great material for making carpets because it has excellent strength. However, shorter fibers cannot offer the same durability and quality as you would find with longer ones, so be sure to choose your wool wisely.
Purity of the fiber: Pure Wool Carpets contain absolutely no synthetic or machine fibers at all. When selecting carpets, there are many things to consider, but one of the most important factors is whether it’s made with pure wool. Any imperfection in this material will show up and ruin your final product.
The color of the wool: Take care when choosing your carpet colours. The lighter the wool, it will be easier to achieve pure and uniform shades in design, so make sure you don’t go with anything too dark or vibrant. Wool is a durable fabric that has been used for centuries. It can be weakened by bleaching, but it’s also important to note how this affects the quality of wool and its fibers over time.
