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。国内再生聚酯纤维处于研究，小规模工业试验阶段。
Regenerated fibers are mainly divided into two categories: regenerated cellulose fibers and regenerated synthetic fibers. Viscose fibers are the earliest regenerated fibers. Later, new regenerated cellulose fibers such as Lyocell fibers, cellulose carbamate fibers, superconducting viscose fibers, kapok fibers and bamboo fibers have emerged. Polyester fibers account for about 70% of synthetic fibers, and the application of polyester in bottle making industry is expanding rapidly, so the regenerated synthetic fibers are mainly polyester fibers. Domestic regenerated polyester fibers are in the stage of research and small-scale industrial test.
