Abstract

A fully-degradable compound nonwoven for cleaning and the manufacturing process thereof consists of a spunbond nonwoven layer and a composite fiber layer; the spunbond nonwoven layer is a degradable spunbond nonwoven layer; the composite fiber layer is a reticular fiber layer formed through wet-laying, and the spunbond nonwoven layer and composite fiber layer are spunlaced into one. Structure and manufacturing process of the invention are simple. The degradable spunbond nonwoven layer and composite fiber layer are spunlaced together; after oven drying and hot rolling, the compound is processed to a nonwoven product with preset patterns on the surface without dropping scraps, wherein the degradable spunbond nonwoven layer can make the product have stronger intensity. The adhesive, Tencel or cotton fiber in the composite fiber layer can be intermeshed during spunlace; in the meanwhile, fiber pulp will also be planted in between the two layers, thereby consolidating the two layers to a net and making the product have strong oil and water absorptivity as well as strong tear resistance.
