Definitions

  • PROCESS FOR TREATING FIBROUS MATERIAL Filed Jan. 18, 1929 Patented July 4, 1933 v um'rso STATES ALFRED UM, OF BEBLm-B'IEGLITZ, GERMANY rnocass FOB 'raparme muons m'rmmu.
  • My invention relates to a process by which fibres and fibrous material, of any kind, whether of animal or vegetable origin, or the products thereof can be separated, opened and cleansed, and fat, oil or pectin removed therefrom by treating them with water in a high-frequency magnetic field for a sufiicient length of time.
  • the cleansing and dissolving steps could only be effected by chemical or mechanical means.
  • the fibres or fibrous material can not only be opened and cleansed or extracted but at the same time bleached or dyed Without being damaged. Under the influence of the high-frequency magnetic field, produced in any known manner, the operation is effected within the shortest possible time and in the most simple manner.
  • the influence of the high-frequency magnetic field is very peculiar.
  • the fibrous material for instance wool, silk, hemp, flax, cotton, ramie, jute, straw, cane, reed, bark, bones, wood etc. is put into a pot or vessel, permeable to electric oscillations and waves, consisting for instance of insulating material, such as glass or earthen ware or other ceramic material filled with water, which pot or vessel is then placed within a flat or spiral coil through which a high-frequency current is passed.
  • insulating material such as glass or earthen ware or other ceramic material filled with water
  • the fats and oils are recovered, but if for instance water containing an alkaline lye is used, the fats and oils will be saponified.
  • the fibres or spun yarns, woven cloths or textile fabrics of any kind can be easily washed.
  • the pectins of the fibres can either be separated entirely by this process or only to a certain degree and can be used later on for stifiening and finishing purposes. If wood is treated in such high-frequency magnetic field the cellulose therein may quickly be obtained.
  • fresh green vegetables can be prepared for food: also meat and fishes can be treated as well as fruits. nuts, etc. Tea, cocoa or coffee may also be extracted by this process.
  • the fibrous material or the products obtained therefrom can be dyed by the same process, the color entering into the cells of the cellulose; the pigment thus introduced cannot be eliminated by washing.
  • the dye is dissolved 388,486, and in Germany January 18, 1928.
  • the degree of separation of the fibres will depend upon the time which the fibres are left in the high-frequency magnetic field. After a certain time the fibres are dissolved entirely and arrived at a colloidal state.
  • a transformer a of usual voltage and cycles produces a highvoltage-current (of 3000 5000 volts, average) across the parallel condenser b and the spark gap 0 through the flat coil (2.
  • the magnetic. high-frequency field around this fiat coil extends into the contents of a pot e of insulating material which is placed on the coil (1.
  • Fig. 2 shows diagrammatically an arrangement of the apparatus.
  • a fiat metal plate f to secure a good contraction of the magnetic lines and to absorb the Foucault or eddy currentsl
  • a cylindrical or spiral coil may be used to produce the same effect, within which the pot or vessel e is placed.
  • the current frequencies will be varied in any desired manner according to the purpose to be attained, and same may rise to or above 1,500,000 oscillations per second.
  • the raw fibre is submerged in water contained in a vessel of glass and the vessel then placed within a spiral or other coil, carrying a high-frequency current, and left there for some time.
  • the se arated fat or oil settlesi on the surface 0 the water and is removed in the ordinary manner.
  • the temperature at which the fibrous material is treated is low and varies of course according to the nature of the fibres or fibrous material being treated and at all events does not rise to a boiling temperature or a temperature which would injure the fibres.
  • an alkaline lye for instance a solution of caustic soda, is employed, and a solution of soap is immediately produced with strong foaming, which soap can be washed out later with ease, leaving perfectly de-fatted fibres.
  • the raw fibre is split simultaneously into its ultimate and finest single fibres without requiring any kind of mechanical manipulation. It is thus possible to produce from any kind of raw fibres, (hemp, flax, cotton, jute, animal-wool, silk) finer yarns of very high tensile strength by means of a most simple process.
  • the fats in the fibres need not be entirely removed in case this should not be required for certain reason.
  • An aqueous soap solution is first prepared to which a dye soluble in water is added.
  • the glass vessel is about half filled with this liquid and a perforated metal plate, preferably of iron, may be placed on the bottom of said vessel.
  • Raw jute is then immersed in the liquid, whereupon .the vessel is placed on a flat metal, spiral, or in a metal coil.
  • the coil, or the spiral is then connected with a source of high-frequency current.
  • the gums are dissolved by reason of the foaming after a short period, and the fibre dyed in grain. The dye quickly penetrates into the cells, even such colors as usually only color the surface.
  • opened fibre i. e., fibre from which the gums have already been removed, it is not necessary to add soap or other solvents. It is however practical to add during dyeing a very small quantity of Turkey red oil.
  • vegetables such as peas, beans, spinach, cabbage, turnips, etc. containingmore or less fibres and means (consisting of animal fibres) are placed in water and exposed to the influence of the high-frequency magnetic field, under addition of soda and common' salt, they will be rendered perfectly soft after a few minutes, and if the influence of the magnetic field is continued long enough, vegetable and meat juices are obtained, which can easily be digested by the human or animal stomach.
  • Coffee, cocoa, or tea extracts can be produced by the same rocess, as they likewise contain vegetable fi res.
  • Fruit and produce, as well as fodder and bones, can be 0 ened within the shortest possible time. 011, fat and glue can easily be recovered from bones.
  • the raw materials of the sugar industry, such as sugar-beets and sugar-cane can be opened in this way and the sugar easily obtained.
  • a process for separating and bleaching the fibres of fibrous material containin fats and oils consisting in immersing the fi rous material in a vessel permeable to magnetic waves containing water havng a slight electrical conductivity; then placing the vessel in a high-frequency magnetic field until the fats and oils are broken down and the fibres separated, and removing the fibres from the vessel and drying the same.
  • the drying operation consisting in placing the bleached fibres in said vessel containing a small quantity of mineral oil, and subjecting the vessel to the influence of said magnetic field to vaporize the oil.
