Patent granted for non-tufted carpet with bonded non-woven structure
A recently granted patent (Publication Number: US11913150B2) discloses a non-tufted carpet design that features a facing layer made of an entangled and partially bonded non-woven structure composed of 100% staple fibers. The bonding process involves thermally activated bonds between two different polypropylene materials, with the first material produced using a metallocene catalyst and having a lower melting point than the second material. The staple fibers are bicomponent fibers with a sheath/core structure, where the first material forms the sheath and the second material forms the core, in a weight ratio of 20:80 to 30:70.
The patent also highlights the recyclability of the non-tufted carpet, emphasizing its sustainable design. The non-woven structure of the carpet has a weight ranging from 100 to 350 grams per square meter, with a normalized stiffness exceeding 150N/%. Additionally, the carpet may include a backing layer for added support, and the non-woven structure specifically weighs between 150-275 grams per square meter. The manufacturing process involves passing the entangled non-woven structure through an oven to achieve the desired bonding without compromising the integrity or form of the fibers, ensuring a durable and high-quality end product.
