A manufactured POLYAMIDE fiber in which the fiber forming substance is any long chain synthetic polyamide having recurring amide groups (-NH-CO-) as an integral part of the polymer chain. The two principal nylons are NYLON 66, which is polyhexamethylene diamine adipamide, and NYLON 6, which is polycaprolactam. These fibers can be produced using spun bonded or carded thermally bonded processes.
