Basic product types include:Fibers and monofilaments -- Single fibers are called filaments and a monofilament is when a single continuous filament is rolled on a spool. Semi-synthetic fibers are made from raw materials with naturally long-chain polymer structure and are only modified and partially degraded by chemical processes, in contrast to completely synthetic fibers such as nylon (polyamide) or dacron (polyester), which the chemist synthesizes from low-molecular weight compounds by polymerization (chain-building) reactions. Different types of yarn fibers have specific qualities — some good, some not so good. Rayon is a synthetic fabric that is made from fibres that are made from naturally sourced cellulose.
