Nanofibers are fabricated in a continuous process by introducing a polymer solution into a dispersion medium, which flows through a conduit and shears the dispersion medium. Liquid strands, streaks or droplets of the polymer solution are continuously shear-spun into elongated fibers. An inorganic precursor may be introduced with the polymer solution, resulting in fibers that include inorganic fibrils. The resulting composite inorganic/polymer fibers may be provided as an end product. Alternatively, the polymer may be removed to liberate the inorganic fibrils, which may be of the same or smaller cross-section as the polymer fibers and may be provided as an end product.

Thermally Expandable Crimped Hollow Fibers and Methods of Using Same

Номер: US20130040121A1

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.
