Greige Fabric Storage Requirements and Preservation Standards
Unfinished greige fabric preservation demands humidity control between 50 and 65 percent relative humidity to prevent size retrogradation and oil oxidation.
Roll Core Collapse
Structural Tube Failure
Internal paperboard cores can buckle under excessive winding tension or heavy radial loading. Unwinding machines fail when roll core collapse deforms the central aperture needed for expanding chuck insertion. Mechanical breakdown occurs in heavy upholstery fabrics, dense industrial canvas, technical textiles and long-yardage roll goods but affects loose folded goods not at all.
Crushed cores prevent automatic feeding into cutting tables.
Winding Stress
Radial forces build exponentially as fabric layers accumulate over the central cardboard tube. Excessive winding tension triggers roll core collapse during storage when outer fabric layers compress inner layers against an inadequate core wall thickness. Core manufacturers specify minimum wall thicknesses based on total roll mass and winding speed.
Increasing core wall thickness from five millimetres to ten millimetres doubles crush resistance.
Stacking Limit
Stacking heavy fabric rolls horizontally places severe compressive loads on lower cores. Warehouses prevent roll core collapse by utilizing specialized cantilever racks instead of pyramid floor stacking. Over-stacking causes core ovality.
Remediation Protocol
Damaged core tubes interrupt automated garment cutting operations. Technicians insert hydraulic expansion plugs into damaged rolls to repair minor roll core collapse before mounting on unwinding stands. Severe collapse requires rewinding the fabric roll onto a fresh core.
