Abstract

The magnetic pocket is an alternative to a fabric pocket or loop on clean room garments. Clean room garments do not generally have pockets to reduce the risk of contaminants, e.g., pocket lint, and instead have fabric loops. Fabric loops have the limitation of only being suited for items with clips. The mechanical action of the clip may also be a source of contamination.

Magnetic Pocket for Clean Room Garments

      The magnetic pocket is an alternative to a fabric pocket or
loop on clean room garments.  Clean room garments do not generally
have pockets to reduce the risk of contaminants, e.g., pocket lint,
and instead have fabric loops.  Fabric loops have the limitation of
only being suited for items with clips.  The mechanical action of the
clip may also be a source of contamination.

      The magnetic pocket consists of a ferromagnetic plate held
within the clean room garment as shown in Version 2 of the Figure.
Magnets are affixed to the items to be carried. The magnet is
attracted to the plate and held in place by friction.

      The prototype consisted of a metal plate joined to a fabric
patch with hot glue as shown in Version 1 of the Figure.  The fabric
patch is attached to the inside of the garment by snap fasteners.
The ability to remove the plate is important to prevent damage during
garment cleaning.  (A production model would most likely be made with
an internal pocket to reduce costs.)  Small ceramic magnets were
attached to sample items:  a pen, a utility knife, and a level, with
hot glue and encapsulated in a thin layer of glue.  The coating was
to prevent the contamination source of the magnet's dust and to
prevent wear of the garment fabric.  Objects carried on the magnetic
pocket did not fall off.

      The magnetic pocket concept is widely applicable beyond the
clean room garment implementatio...
