ABSTRACT:
A bi-component, multifilament synthetic dyeable carpet face yarn that is manufactured using the sheath-core melt spinning process is constructed so as to include a plurality of individual uniformly sheath-cored filaments having a sheath of virgin polyamide (e.g., nylon) and a polymer core that cannot be dyed using standard atmospheric pressure carpet dyeing methods used to dye the sheath filaments. This yarn is a less expensive substitute for 100% polyamide tufted carpet face yarn.
