再生纤维主要分为两大类：再生纤维素纤维和再生合成纤维。粘胶纤维是最早的再生纤维，以后相继出现了新型再生纤维素纤维如Lyocell纤维、纤维素氨基甲酸酯纤维、超导粘胶纤维、木棉纤维以及竹纤维等。聚酯纤维大约占合成纤维的70%，而且聚酯在制瓶行业的应用迅速扩大，因此再生合成纤维以再生聚酯纤维为主。
There are two main types of regenerated fibers: regenerated cellulose fiber and regenerated synthetic fiber. Viscose fiber is the earliest regenerated fiber. Later, new regenerated cellulose fibers such as Lyocell fiber, cellulose carbamate fiber, superconducting viscose fiber, kapok fiber and bamboo fiber appeared one after another. Polyester fibers account for about 70% of synthetic fibers, and the application of polyester in the bottle industry is expanding rapidly, so regenerated synthetic fibers are mainly regenerated polyester fibers.
