Definitions

  • the instant invention utilizes polypyridobisimidazole fiber.
  • This fiber is a rigid rod polymer that is of high strength.
  • the polypyridobisimidazole fiber has an inherent viscosity of at least 20 dl/g or at least 25 dl/g or at least 28 dl/g.
  • Such fibers include PIPD fiber (also known as M5® fiber and fiber made from poly[2,6-diimidazo[4,5-b:4,5-e]- pyridinylene-1 ,4(2,5-dihydroxy)phenylene).
  • PIPD fiber is based on the structure:
  • the polypyridobisimidazole fiber useful in most embodiments of this invention has an inherent viscosity of at least 20 dl/g. Certain embodiments of this invention desire polypyridobisimidazole fibers that have an inherent viscosity of at least 25 dl/g; other embodiments desire an inherent viscosity of at least 28 dl/g.
  • Representative polymer used in the fibrous structures derived from another polymer include polyolefins including polypropylenes, polyethylenes, higher chain polyolefins, and mixtures thereof; polyesters including polyethylene terephthalates, polyethylene napthalates, and mixtures thereof; acrylics; polyamides including nylons; aromatic polyamides including para-ararmids and meta-aramids; cellulosic and cellulose derivative polymers, fluoropolymers including polytetrafluoroethylenes; polybenzazoles, polyimides, polyamide-imides, other aromatic and aliphatic polymers and mixtures thereof.
  • Optional Other Additives include polyolefins including polypropylenes, polyethylenes, higher chain polyolefins, and mixtures thereof; polyesters including polyethylene terephthalates, polyethylene napthalates, and mixtures thereof; acrylics; polyamides including nylons; aromatic polyamides including para-ararmids and meta-aramids; cellulosic and cellulose derivative
  • FIG. 1 there is a block diagram of an embodiment of a wet process for making "wet” pulp in accordance with the present invention.
  • Pulp ingredients 1 are added to container 2.
  • Container 2 is provided with an internal mixer, similar to a mixer in a washing machine.
  • the mixer disperses the ingredients into the water creating the substantially uniform slurry.
  • the mixed slurry is transferred to a first refiner 3 which refines the slurry.
  • the refined slurry can be transferred to a second refiner 4, and optionally then to a third refiner 5.
  • Three refiners are illustrated but any number of refiners can be used depending on the degree of uniformity and refining desired.
  • Example 8 This example illustrates how the pulp of this invention can be incorporated into a automatic transmission paper application.
  • a slurry containing desirable amounts of the pulp of this invention, clay, latex, friction modifiers such as silica and carbon, and diatomaceous is used to form a paper on a paper machine. From the paper, a ring is stamped and the object is soaked in a solution of a binder resin such as phenolic resin. Upon heating to remove residual solvent and to cure the resin, the ring is adhered to a metal plate used in a automatic transmission.
  • a binder resin such as phenolic resin
