  • Patent number: 9273417
    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.

  • Patent number: 8512519
    Abstract: Sulfopolyester thermoplastic resins provide advantages in papermaking processes and in paper products including paperboard. Improvements in wet strength and dry strength of paper products are achieved by addition of sulfopolyester thermoplastic resins and cationic strength additives during the paper making process. The use of sulfopolyester thermoplastic resins in paper products also significantly enhances the repulpability of the paper.
