Definitions

  • complex fibers can be synthesized by synthesizing inorganic particles in a solution containing a fiber such as a cellulose fiber. This is because the surface of the fiber provides a suitable site where the inorganic particles are precipitated, thus facilitating the synthesis of complex fibers.
  • Processes for synthesizing the complex fibers may comprise stirring/mixing a solution containing a fiber and precursors of inorganic particles in an open reaction vessel to synthesize a complex or injecting an aqueous suspension containing a fiber and precursors of inorganic particles into a reaction vessel to synthesize a complex.
  • the liquid jet refers to a jet of a liquid or a fluid containing solid particles or a gas dispersed or mixed in a liquid, such as a liquid jet containing a pulp or a raw material slurry of inorganic particles or bubbles.
  • the gas referred to here may contain bubbles generated by cavitation.
  • the cavitation number ⁇ which is a fundamental dimensionless number representing a cavitation state, is desirably 0.001 or more and 0.5 or less, preferably 0.003 or more and 0.2 or less, especially preferably 0.01 or more and 0.1 or less. If the cavitation number ⁇ is less than 0.001, little benefit is obtained because the pressure difference from the surroundings is small when cavitation bubbles collapse, but if it is greater than 0.5, the pressure difference in the flow is too small to generate cavitation.
  • the jet flow rate of the jetting liquid is desirably in the range of 1 m/sec or more and 200 m/sec or less, preferably in the range of 20 m/sec or more and 100 m/sec or less. If the jet flow rate is less than 1 m/sec, little benefit is obtained because the pressure drop is too small to generate cavitation. If it is greater than 200 m/sec, however, special equipment is required to generate high pressure, leading to cost disadvantages.
  • Classification means include sieves such as meshes, outward or inward flow slotted or round-hole screens, vibrating screens, heavyweight contaminant cleaners, lightweight contaminant cleaners, reverse cleaners, screening testers and the like.
  • Dispersion means include high speed dispersers, low speed kneaders and the like.
  • reaction solution in the reaction vessel can be used in circulation.
  • reaction efficiency increases and a desired complex of inorganic particles with a fiber can be readily obtained by circulating the reaction solution to promote stirring of the solution.
  • the preparation of calcium carbonate by the carbonation process involves using lime as a calcium source to synthesize calcium carbonate via a slaking step in which water is added to quick lime CaO to give slaked lime Ca(OH)2 and a carbonation step in which carbonic acid gas CO2 is injected into the slaked lime to give calcium carbonate CaCO 3 .
  • the suspension of slaked lime prepared by adding water to quick lime may be passed through a screen to remove less soluble lime particles contained in the suspension.
  • slaked lime may be used directly as a calcium source.
  • the carbonation reaction may be performed in the presence of cavitation bubbles.
  • these cellulosic raw materials can be further treated so that they can also be used as powdered celluloses, chemically modified celluloses such as oxidized celluloses, and cellulose nanofibers (CNFs) (microfibrillated celluloses (MFCs), TEMPO-oxidized CNFs, phosphate esters of CNFs, carboxymethylated CNFs, mechanically ground CNFs).
  • CNFs chemically modified celluloses
  • MFCs microfibrillated celluloses
  • TEMPO-oxidized CNFs phosphate esters of CNFs, carboxymethylated CNFs, mechanically ground CNFs
  • Synthetic fibers include polyesters, polyamides, polyolefins, and acrylic fibers
  • semisynthetic fibers include rayon, acetate and the like
  • inorganic fibers include glass fiber, carbon fiber, various metal fibers and the like. All these may be used alone or as a combination of two or more of them.
  • wet and/or dry strength additives can be added. This allows the strength of the complex fiber sheets to be improved.
  • Strength additives include, for example, resins such as urea-formaldehyde resins, melamine-formaldehyde resins, polyamides, polyamines, epichlorohydrin resins, vegetable gums, latexes, polyethylene imines, glyoxal, gums, mannogalactan polyethylene imines, polyacrylamide resins, polyvinylamines, and polyvinyl alcohols; composite polymers or copolymers composed of two or more members selected from the resins listed above; starches and processed starches; carboxymethyl cellulose, guar gum, urea resins and the like.
  • the amount of the strength additives to be added is not specifically limited.
  • compositions of such materials are not specifically limited so far as they contain an acrylamide monomer unit as a structural unit therein, but include, for example, copolymers of a quaternary ammonium salt of an acrylic acid ester and an acrylamide, or ammonium salts obtained by copolymerizing an acrylamide and an acrylic acid ester, followed by quaternization.
  • the cationic charge density of the cationic polyacrylamide-based materials is not specifically limited.
