Before we delve into cleanroom garments, we should have a basic understanding of some of the definitions used in cleanroom garments. This article lists some of the definitions of cleanroom garments commonly used in the workplace, and includes pictures for easy understanding.
aseptic cleanroom
controls designed to minimize the presence of microorganisms
body box
test chamber used to measure the containment properties of a garment set
calendared fabric
form of cloth produced by a process of flattening fabric filaments resulting in a smoother, tighter fabric surface
cleanroom
room in which the concentration of airborne particles is controlled by means of air filtration management, and which is constructed and operated in a manner designed to minimize the introduction, generation, and retention of particles inside the room, and in which other relevant parameters, such as temperature, humidity, and pressure, are controlled
containment
ability of a garment set to restrict the
migration of potential contaminants from inside the garment set to the ambient environment
contaminant
unwanted substance present in or on a material or surface within a cleanroom
controlled environment
environment in which parameters such as temperature, pressure, humidity, contaminant level, and so forth are controlled within specified limits
coveralls (also known as jumpsuit)
one-piece, full-length garment that covers the body ,generally from the neck to the wrists and ankles
denier
unit of fineness used to describe synthetic and silk fibers, based on a mass of 1 gram per 9,000 meters of length, The thicker a fiber is, the stronger and more durable the material will be that is made from it.
fiber
solid object, typically in the form of a thread or filament, having an aspect (length-to-width) ratio of 10 or more
filament
fiber or group of fibers long enough to be observable without magnification, typically 100 um or more in length
float
matrix of intersecting yarns described by the number of consecutive vertical yarn strands crossed by the number of consecutive horizontal yarn strands, inter-locking the warp and weft of a woven fabric
frock
three-quarter-length garment employing a military collar design and a full front closure with snap adjustment at the neck opening; intended to cover the arms and torso, and meet the knees of the wearer; generally used in cleanrooms of less critical air cleanliness classifications
garment
set complete assemblage of body coverings specified for a particular cleanroom application
gowning system
set of specified articles of apparel and accessories, together with specifications governing their donning, use, doffing (removal), reprocessing or replacement, and storage, as well as specifications related to the way in which they interact with equipment, fixtures, and facilities
gram-positive bacteria
three-quarter-length garment employing a military collar design and a full front closure with snap adjustment at the neck opening; intended to cover the arms and torso, and meet the knees of the wearer; generally used in cleanrooms of less critical air cleanliness classifications
knit fabric
fabric made by interlacing threads in a series of inter-connected loops
laminated fabric
fabric manufactured from two or more layers of different materials, bonded together to create a single multi layer structure exhibiting a beneficial blend of the properties of the individual layers
Material Safety Data Sheet (MSDS)
document prepared by a chemical or material manufacturer, describing the composition, reactivity, properties, and hazards of a chemical or material along with recommended safeguards for handling, storage, and use
serge
fabric made by interlacing threads in a series of inter-connected loops
snood cap
net or fabric bag worn to hold the hair at the back of the head, and tied behind the head
warp/weft
1. warp: series of yarn filaments that extend lengthwise in woven fabric
2. weft: series of yarn filaments that are woven crosswise through the warp in woven fabric
woven fabric
fabric made by interlacing threads in a series of inter-connected loops
