Definitions

  • This invention relates to methods of treating natural and synthetic fibers with ultrasonic energy. More particularly, this invention is directed to methods for producing a predetermined set in natural or synthetic fibers.
  • Ultrasonics is a general term referring to the generation, detection, and/0r utilization of vibratory mechanical energy usually but not necessarily beyond the audible range.
  • the equilibrium positions that the polypeptide chains may assume under any set of conditions will depend on the interaction of the various linkages and their relative strengths. Thus, unless some change occurs in the forces within the fiber molecule, such as the keratin molecule, which permits the rearrangement of the molecular structure, it is impossible to impart a permanent configuration to fibrous materials different from that originally present therein. It is clear, however, that upon the breaking of the said attracting linkages, the fibers may be bent or curled in any given configuration after which the broken linkages can be reconstituted in their set conformation, thus rendering the wave or curl permanent.
  • FIGURE 1 is a view in elevation of a hollow tube of transducer material about whichfibers. are shown ,arranged in a circular configuration;
  • FIGURE 2 is a cross sectional view along lines 22 of FIGURE 1;
  • FIGURE 3 is a view inelevation of a transducer incorporated in a comb to effect the straightening of the fibers;
  • FIGURE 4 is an elevational view of another transducer arrangement wherein a hollow tube of transducer is in: serted within a perforated tube about which fibers are wound;
  • FIGURE 5 is a view in elevation of another transducer arrangement utilizing a horn configuration to direct a longitudinal energy wave in a radial direction;
  • FIGURE 6 is an elevational view of another transducer arrangement useful in straightening fibers
  • FIGURE 7 is an elevational view of still another transducer arrangement useful in straightening fibers
  • FIGURE 8 is a view in elevation of another transducer arrangement according to the invention using an outboard driver
  • FIGURE 9 is a view in elevation of another transducer arrangement according to the invention embodying a modulated jet stream
  • FIGURE 10 is an elevational view of another transducer arrangement according to the invention utilizing an ultrasonic bath
  • FIGURE 11 is a view in elevation of a transducer arrangement according to the present invention in the form of a brush useful in straightening fibers.
  • the method of treating natural and synthetic fibers including human hair with ultrasonic energy comprises the steps of arranging and forcibly restraining the fibers in a predetermined configuration, be it curved or straight, applying a coupling medium capable of providing free ions and radicals to the fibers and coupling ultrasonic energy to the fibers via the coupling medium, whereby the fibers will remain in the arranged configuration on removal of the restraining force.
  • FIGURE 1 there is shown a tube 20 of transducer material, such as barium titanate with or without additives and the like, driven by an ultrasonic generator 22.
  • a transducer of this configuration will vibrate in the radial mode as a function of the frequency of the output of the generator.
  • Strands of the fiber 24 to be treated are wound around the transducer and restrained in the wound condition by suitable means, not shown.
  • a coupling medium described below is applied to the fibers to provide an efficient energy transfer from the transducer to the fibers.
  • the coupling medium may also contain dyes, bleaches and/or other fiber treating agents for concurrent action upon the fibers.
  • a high frequency alternating current is fed from generator 22 to transducer 20 where it is converted into mechanical energy and coupled to the fibers 24 through the coupling medium. It is found that after the application of energy for a short period of time, the fibers will remain in the configuration in which they were wound on the transducer substantially indefinitely. This configuration will be retained even though the fibers are subsequently Washed, bleached or subjected to other similar treatment.
  • the liquid coupling medium employed to wet the fibers for better energy transfer from the transducer to the fibers is characterized by having a weak bonding structure which renders the bonds capable of being easily ruptured with the release of free ions and radicals. Such materials appear to greatly enhance the ultrasonic breakage of the fiber molecular linkages, and they also aid in the reorientation thereof.
  • the coupling medium may be selected from a number of chemical materials which fall under the above general classification.
  • the preferred substances for use in this invention are methyl iodide, either in the pure form or as a solution with water; preferably a solution of about 15-20% concentration by volume, and triethanolamine, also both in the pure .form or diluted in like manner with water.
  • methyl iodide is toxic and would have to be utilized in the treatment of natural fibers disassociated from humans such as wigs, etc. There is no significant toxicity related to triethanolamine and it can be successfully employed in the treatment of human hair without fear of any ill effects therefrom.
  • FIGURE 3 illustrates a comb 26 having a bore 28 receiving a transducer 20.
  • the transducer is driven by an ultrasonic signal and fibers wetted with a coupling medium are passed through teeth 30 of the comb, the fibers will assume the configuration they had at the time of passing through the teeth 30.
  • FIGURE 4 shows a spool 32, which may be perforated as at 34, about which fibers may be wound and restrained, which spool is adapted to receive transducer 20.
  • Fibers such as human hair, are wound about about several of these spools, the coupling medium is applied to the fibers and in turn, the transducer is introduced into the spools and energized from a generator.
  • the use of spools 32 permits the use of but a single transducer 20 and driver 22 to service a number of separate fiber treating operations as would be found in applying a permanent wave to a ladys hair.
  • FIGURE shows a different manner of coupling ultrasonic energy from a transducer 20a, through a bar 36 vibrating in a longitudinal mode to fibers 24 wound about the bar.
  • a series of circumferential exponential horn shaped ribs 38 At spaced intervals along bar 36 are provided a series of circumferential exponential horn shaped ribs 38.
  • the horns of ribs 38 operate in a shear mode and serve to effect a transfer of ultrasonic energy from transducer 20a via a plastic material 40 positioned between ribs 38 to fibers 24.
  • FIGURE 6 illustrates another arrangement in which a plate 42 is provided with a series of spaced parallel vanes 44.
  • a transducer 200 is attached to the plate to couple ultrasonic energy thereto and to vanes 44. Fibers carrying a coupling media are passed between vanes 44 and assume the configuration held during such passage.
  • FIGURE 7 illustrates a transducer 20d mounted for rotation on shaft 46 driven from a gear 48.
  • a cylindrical brush 50 is mounted for rotation on shaft 52 spaced from and parallel to shaft 46.
  • Shafts 46 and 52 may rotate in the same direction or different directions, as shown, and shaft 52 may be driven from a gear 54 which may mesh with gear 48.
  • Transducer 20d is driven from an ultrasonic generator and fibers carrying a coupling medium are passed between the transducer 20d and brush 50. The fibers will retain the configuration held when passing over transducer 20d.
  • FIGURE 8 illustrates fibers 24 carrying a coupling medium wound about a solid bar 56 which is driven ultrasonically by transducer 2%.
  • FIGURE 9 illustrates a similar arrangement but wherein the ultrasonic energy is coupled to bar 56 and fiber 24 via a stream of liquid coupling medium, as defined above, modulated by a transducer 20;, issuing from a nozzle 58.
  • FIGURE 10 illustrates a bath 60 of coupling medium driven by an ultrasonic transducer 20ga'nd-through which fibers are passed and subjected to ultrasonic energy.
  • FIGURE 11 illustrates an ultrasonic transducer 20h in the 'form of a brush with bristles 62 attached to the surfaces and an attached handle 64.
  • the arrangement of FIGURE 11 as well as those of FIGURES 3, 6, 7 and 10 are particularly useful in thestraightening of fibers.
  • the frequency of the ultrasonic energy useful in the treatment of fibers according to the present invention does not appear to be critical; however, frequencies above the audible range appear to be most effective.
  • the frequencies most suited to a particular application are determined experimentally and will depend on the size and quality of the fiber treated.
  • the power required will also depend on the size and quality of the fibers and the efficiency of the coupling medium, however, it is believed that a sufficient amount of power must be applied to overcome the forces holding the bonds and break the bonds to permit reorientation thereof.
  • strands of fibers including human hair are wound and restrained about a form and wetted with or subjected to a medium capable of supplying a sufficient amount of free ions and radicals to combine with the broken bonds, such as one of the liquid substances set forth earlier in the specification.
  • a medium capable of supplying a sufficient amount of free ions and radicals to combine with the broken bonds such as one of the liquid substances set forth earlier in the specification.
  • the strands were removed from the form.
  • the hair had assumed a permanent set in the configuration as wound and repeated washing, crushing and drying failed to remove or alter the set materially.
  • Other synthetic fibers, having related chemical structures have been similarly treated with satisfactory results.
  • the fiber is subjected to ultrasonic energy while being restrained in a straightened configuration.
  • the method of treating natural and synthetic fibers to produce a substantially permanent set therein of predetermined configuration comprising the steps of forming the fibers into a predetermined configuration about an ultrasonic transducer, restraining the fibers in said configuration, applying a coupling medium to said fibers, said coupling medium characterized by having a weak bonding structure adapted to be easily ruptured releasing free ions and radicals, and subjecting the fibers to ultrasonic energy from said transducer via the coupling medium while in the restrained configuration.
  • transducer is a solid core having a plurality of exponential horn shaped ribs spaced longitudinally along the surface 5 thereof and which core is driven in a longitudinal direction by means of an ultrasonically energized transducer coupled thereto and to the fibers.
  • the method of treating natural and synthetic fibers to produce a substantially permanent set therein of predetermined configuration comprising the steps of forming the fibers into a predetermined configuration about a form, restraining the fibers in said configuration, impinging a jet of a liquid coupling medium on the fibers, said coupling medium characterized by having a weak bonding structure adapted to be easily ruptured releasing free ions and radicals, and modulating the jet by ultrasonic energy from an ultrasonic transducer.
  • liquid coupling medium impinged on the fibers is selected from the group consisting of methyl iodide, triethanolamine and aqueous solutions thereof.
  • the method of producing a substantially permanent wave in human hair comprising the steps of winding and securing a portion of the hair about a cylindrically ultrasonic transducer coupling means, dampening the wound hair with a coupling fluid characterized by having a weak bonding structure adapted to be easily ruptured releasing free ions and radicals, applying ultrasonic energy to said coupling means and removing the ultrasonic energy from the coupling means while the hair is secured thereto.
