Abstract
A versatile binder comprising at least one or more sulfopolyesters is provided. These sulfopolyester binders can enhance the dry tensile strength, wet tensile strength, tear force, and burst strength of the nonwoven articles in which they are incorporated. Additionally, the water permeability of these binders can be modified as desired by blending different types of sulfopolyesters to produce the binder. Therefore, the binder can be used in a wide array of nonwoven end products and can be modified accordingly based on the desired properties sought in the nonwoven products.
