PROBLEM TO BE SOLVED: To provide a recycled polyamide crimped yarn that is of a resource-recycling type, has fiber physical properties equal to those of conventional ones, and is excellent in bulky properties, and to provide a method for producing a recycled polyamide crimped yarn which has long-term productivity as conventional ones.SOLUTION: The recycled polyamide crimped yarn is obtained by blending 5-80 mass% of a material recycled polyamide resin (A) and 20-95 mass% of a polyamide resin (B) that is other than the (A), and is characterized in that a single fiber cross-section of the crimped yarn is a modified cross-section and/or a hollow cross-section. The recycled polyamide crimped yarn is suitably used as a resource-recycling type crimped yarn mainly for carpet uses such as car mats, tile carpets, roll carpets, rug mats, and dust control mats. |
