Patent number: 9273417Abstract: 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.Type: GrantFiled: October 14, 2011Date of Patent: March 1, 2016Assignee: Eastman Chemical CompanyInventors: Rakesh Kumar Gupta, Melvin Glenn Mitchell, Daniel William Klosiewicz, Mark Dwight Clark, Chris Delbert Anderson, Marvin Lynn Mitchell, Paula Hines Mitchell, Amber Layne Wolfe
