Definition
Raw, unfinished fabric in the state it comes off the loom or knitting machine, before it has been bleached, dyed, coated, or chemically treated. In aircraft fabric covering work, greige goods are the base woven cloth (typically polyester or cotton) supplied to the manufacturer or finisher for further processing into a certified covering material.
Plain English
Cloth in its plain, untreated state, just as it came off the weaving machine. No dyes, no coatings, no finishing chemicals — just the bare fabric, ready to be processed into something usable.
Context Anchor
Seen in aircraft fabric-covering and materials discussions, especially when describing the condition of fabric before finishing.
Derivation
From the French 'grège,' meaning raw silk — silk in its natural, unprocessed state. The word was borrowed into English textile trade language to describe any fabric in its raw, untreated condition. Knowing this helps explain why 'greige' specifically points to an unfinished stage rather than a color or material type.
Why Pilots Care
Mechanics and owners doing fabric work on certificated aircraft must use approved covering materials, not raw greige cloth. Understanding that greige is an intermediate stage helps clarify why finished, tested, and certified fabrics are what actually get installed on an airframe.
Intuition Check
Greige may look like it means a gray-beige color. In this context, it means unfinished fabric, not the fabric’s color.
Example Sentence 1
The polyester covering fabric starts as greige goods at the mill before being heat-shrunk, coated, and certified for aircraft use.
Example Sentence 2
Greige material must be inspected for defects before being applied to the airframe structure.
