An object of the present invention is to provide a sanitary article-derived recycled fiber that has few impurities and is excellent in appearance and strength. Regenerated fibers with an ultra-superabsorbent polymer (SAP) content of less than 10% obtained by reprocessing sanitary products containing cellulose pulp have a good appearance of the regenerated fibers themselves, and molded products using regenerated fibers are also available. Excellent appearance and strength suitability. Further, as the regenerated fiber, it is preferable that the impurity area ratio measured by a staining method using cobalt (II) chloride hexahydrate is 50,000 mm 2 / m 2 or less and the Canadian standard freeness is 600 ml or more.本発明は、夾雑物が少なく外観性や強度適性に優れた、衛生用品由来の再生繊維を提供することを課題とする。 セルロースパルプを含む衛生用品を再生処理して得られる、超高吸水性ポリマー（ＳＡＰ）量が１０％未満である再生繊維は、再生繊維自体の見た目が良好で、再生繊維を用いた成型品も外観性や強度適性に優れる。さらに再生繊維としては、塩化コバルト（ＩＩ）六水和物を用いた染色法で測定した夾雑物面積率が５０，０００ｍｍ２／ｍ２以下、カナダ標準濾水度が６００ｍｌ以上であることが好ましい。
