Polyamide 6,6 has greater resilience, a higher melting point, and lower stain permeability than polyamide 6, which makes polyamide 6,6 perfect for carpet.[2]

The most notable characteristic of both polyamide 6 and 6,6 is versatility. Although originally developed as an “artificial silk,” it has been used for a vast variety of applications. Polyamide fibres are used for garments, sheer hosiery, parachute cloth, backpackers' tents, bridal veils, musical strings, rope, broom and tooth brush bristles, Velcro and many other applications.[3]

Polyamide 6 and 6,6 are machine washable, dry quickly, need little pressing, and holds shape well since they neither shrinks nor stretches, thereby minimizing water and energy use associated with consumer care and washing.[4]

Due to their durability and abrasion resistance, some Polyamide 6 and 6,6 products have the potential to last and be worn many times, optimizing the energy and resources embodied in the product.
