Debonders for Use in Papermaking

Номер: US20120006499A1
Автор: David S. Soane, Gangadhar Jogikalmath, Lynn Reis, Scott I. Rabin
Принадлежит: NanoPaper LLC

Debonding compositions and methods are disclosed for use in fibrous compositions such as paper-based products. In some instances, debonding agents can be combined with fibers (e.g., cellulose-based fibers) to produce a material having substantial wicking properties while decreasing fiber-fiber interactions that can require substantial energy to overcome in materials processing. In some instances, the debonding agent can act to create a paper-based product exhibiting a transition temperature in which the agent has a higher affinity for the fibers at temperatures above the transition temperature, and the product exhibiting enhanced wicking properties at temperatures below the transition temperature. As an example, a debonding agents can include polymers or other material exhibiting a lower critical solution temperature. The disclosed debonding agents can provide benefits over existing debonding agent formulations such as ammonium salts.

Thermally Expandable Crimped Hollow Fibers and Methods of Using Same

Номер: US20130040121A1
Автор: Kapil M. Singh
Принадлежит: International Paper Co

Thermally expandable crimped hollow fibers having expandable regions interconnected with crimped portions are provided. The crimped hollow fibers may be formed from any hollow polymer fiber that is capable of being crimped and is reactive to heat. Pressure, such as from two opposed mating crimping dies, is applied to portions of a hollow polymer fiber to compress or crimp portions of the fiber, thereby leaving uncrimped or expandable regions containing an expandable substance. In use, the crimped hollow fibers may be contacted with cellulose fibers in the wet-end section of the paper-making process and the resulting mixture formed into a web of entangled fibers. Heat from the dryer section expands the expandable substance in the expandable portion of the crimped hollow fiber to bulk the thus formed paper product. The crimped hollow fibers are especially useful in papers having a basis weight from about 20 to about 200 gsm.

Автор: Andrea Schneider, David S. Soane, Gangadhar Jogikalmath
Принадлежит: NanoPaper LLC

Disclosed herein are systems and methods for attaching particulate additives to a population of cellulose fibers dispersed in an aqueous solution. The cellulose fibers are treated with an activator that forms complexes with them. The particulate additive is attached to a tether that is capable of interacting with the activator, thereby forming a tether-bearing particulate additive. The tether-bearing particulate additive can be added to the activated suspension of cellulose fibers. The resulting interaction between the tether and the activator forms durable complexes that attach the particulate additive to the cellulose fibers. Using these systems and methods, useful additives like starches can be attached to cellulose fibers, imparting advantageous properties such as increased strength to paper products formed thereby. These systems and methods are particularly useful for papermaking involving virgin pulp fibers, recycled fibers, or any combination thereof.

The invention relates to fibrous structures having desirable physical properties, such as good tensile strength, low stiffness and high bulk, manufactured using a fiber furnish comprising cellulosic fibers having a pH of 5.0 or less and at least one strength resin. Not only do structures prepared with acidic fibers have desirable physical properties, they may also be manufactured in an energy efficient manner. To achieve the greatest energy savings it is generally desirable that acidic fibers not be subjected to mechanical treatment, such as by refining, prior to forming the fiber into a fibrous structure. Further, it may be desirable to subject the remainder of the fiber furnish to a minimal degree of mechanical treatment, such as by refining, so as to produce a furnish having a freeness greater than about 550 mL.

These include items such as paper towels, facial tissues and toilet tissues. These paper products can have various desirable properties including wet and dry tensile strength, absorbency for aqueous fluids (e.g., wettability), low lint properties, desirable bulk and softness.Absorbency is the measure of the ability of a product and its constituent webs, to absorb quantities of liquid. Current toilet tissue papers are less absorbent. Furthermore, in order to remove excess waste and dirt from passing through the tissue during use, consumers perform various compensating actions. For example, many consumers select several tissues at once. Such practices lead to more usage of tissues unnecessarily. Moreover, flushing too many tissues may cause plumbing problems such as clogged pipes.People commonly use toilet paper to clean themselves when using the restroom. However, ...
