Farbenindustrie (which marketed it as Perlon), nylon 6 was developed as a dyable, durable nylon fiber intended  to compete with DuPont's nylon 6,6. It is very similar but has a lower melting point and a greater affinity for dyes. The two types of polyamide fiber remain the most commonly used by the textile and plastics industries worldwide. It is formed by polymerizing caprolactam under high pressure and is thus also known as polycaprolactam. ]]></dc:description></metadata>
