  • Patent number: 9617685
    Abstract: A process of making a paper or nonwoven article is provide. The process comprising: a) providing a fiber furnish comprising a plurality of fibers and a plurality of binder microfibers, wherein the binder microfibers comprise a water non-dispersible, synthetic polymer; wherein the binder microfibers have a length of less than 25 millimeters and a fineness of less than 0.5 d/f; and wherein the binder microfibers have a melting temperature that is less than the melting temperature of the fibers; b) routing the fiber furnish to a wet-laid nonwoven process to produce at least one wet-laid nonwoven web layer; c) removing water from the wet-laid nonwoven web layer; and d) thermally bonding the wet-laid nonwoven web layer after step (c); wherein the thermal bonding is conducted at a temperature such that the surfaces of the binder microfibers at least partially melt without causing the fibers to melt thereby bonding the binder microfibers to the fibers to produce the paper or nonwoven article.

  • 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.
