Fabric Guidelines for Cleanroom Apparel

Nov 28th 2013

Check out our large selection of cleanroom apparel.

One of the largest contributors to cleanroom contamination is the people and their movement throughout the cleanroom. Fabrics used for launderable clean room suits are designed for specific applications and spaces. Whether protecting the environment from the worker or the worker from the environment these fabrics provide a barrier to micron size particles.

Styles of Cleanroom Apparel include:

● Clean Room Coveralls
● Clean Room Frocks
● Clean Room Eyes Only Hoods
● Clean Room Open Face Hoods
● Clean Room Boots
● Clean Room Shoe Covers
● Clean Room Fanny Packs
● Clean Room Bouffant Caps
● Clean Room Beard Covers
● Clean Room Lab Coats
Protective Fabrics for Different Environments
● General Cleanroom Use
● Antimicrobial Properties
● ESD Properties
● High Filtration Efficiency
● Arc Flash Protection or Flame Resistant
