Viscose fiber with high bacteriostatic activity and preparation method thereof

The invention discloses a viscose fiber with high bacteriostatic activity and a preparation method thereof, belonging to the technical field of fiber preparation. The viscose fiber with high bacteriostatic activity has a beating degree of 16-25-degree SR, a breaking length of 4-6 km, a folding endurance of 65-80 times, a whiteness of 22-25% ISO, a potassium permanganate value of 80-100 and a bacteriostatic rate of more than or equal to 90%. The preparation method of the viscose fiber with high bacteriostatic activity comprises material preparation, cook and antibacterial treatment; the cookingmethod uses less cooking liquid medicine, does not contain a sulfide, has short cooking and heat preservation time, and is an economical and environment-friendly cooking method. 本发明公开一种具有高抑菌活性黏胶纤维及其制备方法，属于纤维制备技术领域，所述具有高抑菌活性黏胶纤维打浆度为16～25°SR，裂断长为4～6km，耐折次数为65～80次，白度为22～25%ISO，高锰酸钾值为80～100，抑菌率≥90%。所述具有高抑菌活性黏胶纤维的制备方法包括备料、蒸煮、抗菌处理，所述的蒸煮方法所用的蒸煮药液少，不含硫化物，蒸煮和保温的时间短，是一种既经济又环保的蒸煮方法。
