Standardized Visual Defect Classification Methods for Greige Cloth Inspection
Standardized greige inspection combines calibrated D65 illumination and 4-point scoring to convert visual cloth defects into precise commercial deductions.
Pick Finding Marks
Restart Irregularity
Imperfect yarn alignment often occurs when a loom is restarted after a weft break or a bobbin change. This disruption leaves pick finding marks in the woven linen, appearing as narrow bands of altered weft density across the fabric width. This error occurs because the loom must find the correct pick sequence before resuming operation.
It results in a visible line that degrades the appearance of the finished textile.
Mechanical Influence
Mechanical adjustment of the cloth fell position is critical when the loom starts again. If the weft yarn is beaten into the fabric before the loom has reached its full operating speed, the spacing is uneven. When the operator manually adjusts the weft find mechanism incorrectly, the fabric will show a heavy or light line.
This defect is particularly visible in fine linen where the yarns are thin and closely spaced. Modern looms use automatic pick finding systems to minimize these starting lines.
Quality Assessment
Quality inspectors evaluate these starting lines on the inspection table using standard demerit systems. Recording the frequency of these lines helps to identify loom models that require adjustments to their starting programs. It ensures that the fabric quality remains high for high-end linen products.
