Abstract
A plant-based functional polypropylene spunbond non-woven fabric and a preparation method of the plant-based functional polypropylene spunbond non-woven fabric are provided. The plant-based functional polypropylene spunbond non-woven fabric contains a plant herb water-soluble extract in a weight percentage range of approximately 0.2%-1.5%. The plant-based functional polypropylene spunbond non-woven fabric has moisture regain in a range of approximately 0.2%-3%, a longitudinal breaking strength of approximately ≥18.5 N/5 cm, a transverse breaking strength of approximately ≤9.5 N/5 cm, a thickness in a range of approximately 0.2 mm-0.5 mm, a weight per unit area in a range of approximately 20 g/m2-40 g/m2, and a fiber diameter in a range of approximately 10 μm-30 μm.
