  • Patent number: 7144474
    Abstract: Fiber treated with an organic nonpolymeric binder is combined with superabsorbent particles in order to bind the particles to the fiber. The nonpolymeric organic binder comprises binder molecules that include at least one functional group capable of forming a hydrogen bond or a coordinate covalent bond with the particles and at least one functional group capable of forming a hydrogen bond with the fiber. The superabsorbent particles have a hydrogen or coordinate covalent bonding functional site. The binder serves to bind the particles to the fiber through formation of hydrogen and/or coordinate covalent bonds.

  • Patent number: 7018490
    Abstract: A binder is applied to particles which are then combined with fibers to bind the particles to the fibers. The particles have functional sites for forming a hydrogen bond or a coordinate covalent bond. The fibers have hydrogen bonding functional sites. The binder comprises binder molecules, the binder molecules having at least one functional group that is capable of forming a hydrogen bond or a coordinate covalent bond with the particles, and at least one functional group that is capable of forming a hydrogen bond with the fibers. A substantial portion of the particles that are adhered to the fibers may be adhered in particulate form by hydrogen bonds or coordinate covalent bonds to the binder, and the binder in turn may be adhered to the fibers by hydrogen bonds. Fibers containing particles bound by this method are easily densified.

  • Patent number: 6719862
    Abstract: A highly densifiable wood pulp product is disclosed. In one embodiment, the densifiable product includes fibers having low coarseness, preferably having a fiber coarseness less than about 22 mg/100 m, and a densifying agent. In another embodiment, the densifiable product further includes fibers having coarseness greater than about 22 mg/100 m. Juvenile wood fibers are the preferred source of fibers having low coarseness. A densified pulp product formed by compacting a fibrous composite that includes fibers having a fiber coarseness less than about 22 mg/100 m, a densifying agent, and optionally, fibers having coarseness greater than about 22 mg/100 m is also disclosed. The pulp products can be advantageously incorporated into absorbent articles and can optionally further include superabsorbent material. Methods for forming the densifiable and densified fibrous products are also disclosed.

  • Patent number: 6340411
    Abstract: A densifying agent is applied to fibers in order to improve the densification properties of the fibers. The fibers have hydrogen bonding functional groups. The densifying agent are denser than the fibers to which the densifying agent is applied. The densifying agent can be organic or inorganic. The improved densification properties are observed without the presence of particles bound to the fibers or in the presence of particles that are not bound to the fibers. Softening agents can also be applied to the fibers in order to soften the fibers and articles including such fibers. Softening agents may be selected from the group of densifying agents.

  • Patent number: 5693411
    Abstract: Improved fibers are provided that may be incorporated into absorbent articles such as disposable diapers, feminine hygiene appliances, and bandages. Water soluble particles are bound to fibrous material by a binder in which the particles are sparingly soluble and which has a volatility less than water. The binder has a functional group capable of forming a hydrogen bond with the fibers, and a functional group that is capable of forming a hydrogen bond or a coordinate covalent bond with the particles. The binder can be activated or reactivated by addition of heat, liquid, or mechanical energy such that fibers treated with binder may be shipped to a distribution point before particles are bound to the fibers.
