Question & Answer

  • It usually appears to be a long thin natural fabric stick or beam(wood, bamboo, or plastic)
  • It must be with one end covered with either cotton, foam, rayon, or synthetic plastic fiber
  • Some types are with a breakpoint at a certain length on the stick or beam
Generally, a medical swab is for:
  • specimen collection
  • skin disinfection
  • or wound treatment
Medical swabs are probably the most common single-use tool in day-to-day medical activities.
  • Shall be able to collect as much amount of specimens as possible at one time
  • Shall be able to release the specimen collection to the maximum amount easily and quickly
  • Shall be able to bend over and be resilient for deep and far-reaching collection spot
  • Shall bear no substances that may affect later analysis or assay
  • Shall release as less as possible fabrics of which the tip or stick is made with
  •  Cotton
  • Rayon(man-made spun fiber from wood)
  • Polyester(PET)
  • Foam(polyurethane or polyethylene)
  • Nylon(polyamide）
All these tips are tested less ideal in releasing specimens collected, due to either fabric property or the structure formed from the way these fabrics are wrapped on the stick end.
With the information and knowledge, you get from answers to the above questions, the below production illustrates how a flock or flocked swab is made and why it is called flocked:
  1. the stick is made with one end has already the ultimate tip shape, normally with the injection molding process;
  2. the tiny nylon fibers(as you see on the tip of a ready-made swab) is put into a cabinet that is charged with electrostatics;
  3.  the stick tip is glued and put into the fiber cabinet;
  4.  with the pull of the electrostatics, the nylon fibers will fly toward the glued tip of the stick and be glued perpendicularly on the glue-covered tip surface;
  5. the key process is over and the tip is made, following steps is usually heating, drying, cleaning and packing;
  • fiber density is too less and height is too short that reduces the ability to collect and retain;
  • fiber is loosed glued and will fall off during each step afterward and even when touching the body of the patient
  • other defects not directly identifiable include, undried glue, excessive levels of formaldehyde(primarily coming from the glue)
With a flocked tip, 90% of specimens collected can be easily eluted down for diagnostic analysis, while all other spun fiber tips retain 90% of the specimen in their mattress structure and can not get down as easily as from a flocked tip.
YES, sure with no doubt.
Our flocked swabs are EO(ethylene oxide) sterilized.
