发明名称 RECYCLED FIBER AND RECYCLED FIBER MOLDING
摘要 The present invention aims to provide recycled fibers having a low dirt content and excellent appearance and strength properties derived from sanitary products. Recycled fibers having a superabsorbent polymer (SAP) content of less than 10% obtained by subjecting a sanitary product containing a cellulose pulp to a recycling process per se have good appearance, and moldings prepared by using the recycled fibers also have excellent appearance and strength properties. Further, the recycled fibers preferably have a dirt area fraction of 50,000 mm2/m2 or less when determined by a staining assay using cobalt (II) chloride hexahydrate, and a Canadian standard freeness of 600 ml or more.
