This is for Textile engineering students so they must have a complete grip of Inspection methods being used in industry 4 Point System is demonstrated thoroughly

1. FABRIC INSPECTION

2. INSPECTION DEPARTMENT
Apparel manufacturers inspect the fabric stock
upon arrival, so that any fabric irregularities are
caught early in the production process.

3. IMPORTANCE OF FABRIC INSPECTION
Fabric inspection is done for:
• Faults/defects,
• Fabric construction,
• Fabric weight,
• Shrinkage,

4. PROCESS OF FABRIC INSPECTION
• End to end or edge to edge shading,
• Color,
• Hand feel,
• Length/width,
• Print defect and appearance.

5. Faults
• Abnormality that hinders acceptability
• 45%-65%

RUNNING DEFECTS:
Any major defect found to repeat and / or run in a continuous manner will constitute a running defect. All
major running defects must be assigned four penalty points to every meter in the roll where it occurs.
FULL WIDTH DEFECTS:
A full width major defect would cause that meter of fabric to be assigned four penalty points.
FABRIC WIDTH:
Fabric width will be checked minimum of three times during the inspection of a roll (beginning,middle and end
of the roll).Rolls having width less than the specified are potential problems. In such cases width deviation of
more than 1% would constitute a major fault. Overall, fabric width is measured from out side of the selvage to
the outside of the opposite selvage.
ROLL LENGTH:
Rolls having meters less than that stated on the packing are a problem. Any roll having more than 1% lesser
fabric than that specified is rejected. The entire shipment shall be rejected if the total measured meters in the
sample audit are more than 1% short that what is declared on the packing.

8. FABRIC INSPECTION SYSTEMS
Fabric inspection ensures to minimize the rejection of cut
panels or rejected garments due to fabric faults.
There are following three inspection systems:
1. 4-Point System
2. 10-Point System
3. Dallas System
