Defect Classification
Systematic visual and sensor inspection of unfinished loomed textile rolls evaluates structural uniformity before wet chemical processing begins. Technicians conduct greige fabric auditing at automated or lighted manual inspection perches to identify spinning irregularities, broken warp ends, thick picks and foreign matter before goods enter scouring or bleaching ranges. In Chinese linen mills, off-loom linen naturally exhibits flax slubs and seed coat fragments that must be categorized as natural cellulosic characteristics rather than severe mechanical faults.
Auditors separate structural flaws caused by misdrawn harness wires or loom stops from inherent plant fiber variations. The inspection routine stops at the grey state boundary, as it does not evaluate dye uptake or chemical finish performance applied in subsequent processing stages.
Point Allocation
Standard evaluation tables assign penalty points to detected imperfections according to their measured length and severity on the inspection frame. Quality controllers performing greige fabric auditing apply the international four-point system or domestic mill grading rules to determine whether a greige roll achieves first quality or industrial utility grade. Deficiencies spanning up to three inches receive one penalty point, while flaws extending beyond nine inches incur four points, which is the maximum score assigned to any single linear yard.
Running warp streaks and continuous mispicks quickly push a roll past the typical acceptance limit of twenty points per one hundred square yards. A single hundred-meter greige linen roll carrying excess slub clusters or reed marks is segregated immediately for second-grade retail or mechanical shearing rework. Inspection perches record these tallies directly into the production ledger, linking roll serial numbers with specific loom assignments.
Shift supervisors examine these defect logs each morning to adjust rapier tensions and replace worn harness components before mass production suffers.
Finishing Authorization
Batch release documentation generated at the grey inspection station determines whether loomed rolls proceed to continuous bleaching lines or undergo mechanical mending. Dye house managers review results from greige fabric auditing before batching lots into caustic boil-off tanks, because dye will highlight structural flaws rather than conceal them. Rolls that fail contractual threshold scores are diverted to natural un-dyed product lines or sold at markdown to regional converters.
Approval signatures on the grey release ticket protect finishing plants from liabilities associated with downstream printing or tailoring rejects.
