Dimensional Stabilization
Protective physical and environmental control maintains raw fabric geometry immediately after fabric production finishes. Mill execution of loom-state preservation prevents structural relaxation, skewed pick density, fabric bow, and yarn contraction in untreated grey goods. Grey fabrics exiting shuttleless looms possess high internal stress within warp and weft yarns.
Controlled humidity and low tension rolling protect unwashed fabric dimensions during intermediate warehouse storage. The stabilization state ends when wet finishing processes wet out the fabric.
Moisture Control
Relative humidity within grey cloth storage rooms must remain between sixty and sixty-five percent. Moisture fluctuations induce uneven regain rates across roll edges.
Storage Barrier
Polyethylene wrapping isolates loom-state rolls from ambient dust, airborne oil mist, industrial ozone, and sunlight exposure. Uncovered grey cloth absorbs airborne hydrocarbons that interfere with subsequent scouring baths. Tight core winding prevents edge curling and selvage distortion on heavy canvas rolls.
Extended storage under high compression induces permanent crease lines.
Quality Standard
Physical inspection measures roll width, end count, total weight, and pick count prior to storage allocation. Comparison of grey roll measurements against fabric manufacturing specifications verifies structural uniformity. Deviation exceeding one percent in pick density signals tension loss during winding.
Preserved rolls transfer to dye houses with predictable shrinkage profiles.
