Flocked Swab for Optimal Sample Collection and Diagnostic Testing

      Huachenyang flock swab is a solid molded plastic applicator shaft with a tip that can vary in size

and shape.  The tip of the applicator is coated with short nylon fibers that are arranged in a perpend-

icular fashion.  This perpendicular arrangement results from a process called flocking, where the fibers

are sprayed onto the tip of the swab, while it is held in an electrostatic field.  The process creates a highly

absorbent thin layer with an open structure. 


      Unlike traditional fiber wound swabs, which resemble a mattress or cushion, flocked wabs have no

internal absorbent core to disperse and entrap the specimen.  The entire sample stays close to the surf-

ace for fast and complete elution.  The perpendicular nylon fibers serve as a soft brush and allow improved

collection of cell samples.  Capillary action between the fiber strands facilitates strong hydraulic uptake

of liquid sample, and the sample stays close to the surface allowing easy elution.
