  • Selective polyamide recovery from multi-component materials
    Patent number: 5889142
    Abstract: A process for selectively separating polyamides from multi-component waste materials including the steps of subjecting the multi-component mix to a specific mixture of caprolactam and water at a preselected temperature range below the degradation temperature of the polymer to be recovered, separating the formed polyamide solution, and recovering the desired polyamide. The process is very desirable for separating multi-component waste materials which contain not only nylon 6, but also nylon 6,6. The recovered polyamide may be used in molding applications and in fiber such as carpet fiber.
