Abstract:
A fiber treatment device comprising:an ultrasound generator capable of converting electrical energy to a mechanical vibration having a topically efficacious frequency; a comb device coupled to said ultrasound generator and having a proximal end and a distal end and responsive to said topically efficacious vibrations; a reflector with a reflectance, R, disposed on said distal end of said comb device; and, wherein said reflectance is expressed as: |R|>0; wherein&it;â€ƒ&it;R=Z2-Z1Z2+Z1;â€ƒwherein Z1=acoustic impedance of wet fiber; and, Z2=acoustic impedance of said reflector; â€ƒwherein Z2=&rgr;2c2; and, Z1=&rgr;1c1; and, â€ƒwherein &rgr;1=density of wet fiber; &rgr;2=the density of said reflector; c1=the acoustic velocity in wet fiber; and, c2=the acoustic velocity in said reflector.
