Standard Setup Rules for Four Point Greige Perches
Standard four-point greige perches require a 45-60 degree tilt, 1200+ lux D65 lighting, synchronized tension drive, and strict ASTM D5430 demerit point scoring.
Rapier Loom Greige
Unfinished Fabric
The raw, unprocessed linen fabric that comes directly off a weaving machine has not yet been washed, bleached, or dyed. This rapier loom greige carries the oils and starches applied to the warp yarn to assist the high-speed weaving process. It is stored in the gray-goods warehouse under humidity-controlled conditions.
This storage prevents the natural fibers from mildewing.
Quality Characteristics
The mechanical action of the rapier insert ensures that the weft yarn is placed with high precision, giving the raw cloth a uniform density. However, because rapier loom greige remains unfinished, it contains loose warp fibers, sizing chemicals, and natural flax impurities. These materials must be removed during subsequent finishing to reveal the true texture of the linen.
The fabric at this stage is stiff and exhibits a natural brownish or cream color.
Inspection Protocol
Inspectors examine the raw fabric immediately after it is unloaded from the loom to identify any structural defects before wet finishing occurs. They record the weave density and fabric width on the greige inspection sheet to ensure compliance with the initial production plan. If the rapier loom greige exhibits repetitive tension errors, the maintenance team is alerted to recalibrate the loom before the next run begins.
This early detection ensures that only high-quality fabric is sent to the dye house, where repairs are much more difficult and expensive to perform. The resulting data becomes the baseline for assessing total process yield.
