Abstract
A blend of conventional carpet fibers (e.g. nylon fibers) and high shrinkage fibers (e.g. acrylic fibers) is described. Saxony carpet made from the blend has better appearance retention characteristics than corresponding saxony carpet made from the conventional carpet fibers.
Claims17
A blend of fibers comprising carpet fibers and high shrinkage fibers, the carpet fibers being crimped fibers having deniers of at least 10 (dpf) and shrinkages of less than 12%, the high shrinkage fibers being fibers having shrinkages of at least 12%, the quantities and shrinkages of said carpet fibers and said high shrinkage fibers being such that when a saxony test carpet having a pile made from heatset yarn which prior to being heatset consists of said blend of fibers is subject to 40,000 traffics, the appearance thereof is better with respect to tuft endpoint definition and lack of matting, as determined by Test A, than corresponding test carpet having a pile made from heatset yarn which prior to being heatset consists entirely of said carpet fibers.
A blend of staple fibers having an average length in the range of 6 to 9 inches (15 to 23 centimeters) and consisting essentially of crimped carpet staple fibers and high shrinkage staple fibers in a weight ratio ranging from 60:40 to 95:5, carpet staple fibers to high shrinkage staple fibers, said carpet staple fibers being selected from the group consisting of nylon staple fibers, polyester staple fibers and mixtures thereof and having shrinkages less than 8%, deniers of at least 12 and a crimp frequency in the range of 5 to 17 crimps per inch (2 to 6 crimps per cm), said high shrinkage staple fibers being staple fibers having shrinkages of at least 12% and at least 10 shrinkage units higher than the shrinkages of said carpet staple fibers.
