2. Objectives of Fabric Inspection:
To assure either the quality of fabric fulfill the expected requirements.
To detect the fabric defects and nonconformance at early stage.
To satisfy customer.

3. Advantages of fabric inspection:
Improve product quality
Minimize waste
Reduce the cost
Avoid short shipment and order cancellation
Increase Productivity

4. Grading Systems:
There are different types of grading systems that are used in industry for fabric inspection. A system is selected by mutual acceptance of buyer and supplier.
Some of the available grading systems are
4 Point System
10 Point System
Graniteville 78 System
6 Point System
Dallas System

5. 4 Point System: Important Point to be considered during inspection:
Defect must be measured lengthwise
Maximum penalty points per yard are four.
Defects within 1\2" on selvedge not considered.
Acceptance level up to 40 points/100 sq yard.
Rejection will occur above 40 points/100 sq yard.
Defect must be marked properly by using stickers.

6. Defect Classification by using four point system: Size of Defect
Penalty
3 inches or less
1 Point
Over 3, but not over 6 inches
2 Points
Over 6, but not over 9 inches
3 Points
Over 9 inches
4 Points

7. 10 Point System:
It is earliest inspection system and is designed to identify defects and to assign each defect a value based on severity of defect.
Grading is designed to apply to every imperfection according to size regardless of type.
No one yard should be penalized more than 10 points.
A combination of both warp and weft defects when occurring in one yarn should not be penalized more than 10 points.
Any warp or weft defect occurring repeatedly throughout the entire piece makes it second grade fabric.

8. Defect Classification by using 10 point system:
10 point system is mainly used for woven fabrics.
Warp Defects:
Size of defect
Penalty
Up to 1 inch
1 point
1-5 inch
3 point
5-10 inch
5 point
10-36 inch
10 point

9. Weft Defects: Size of defect Penalty Up to 1 inch 1 point 1-5 inch
5 inch to half width
5 point
Full width
10 point

10. First Quality: Second Quality:
A piece is graded as first quality if the total quality points does not exceed the total yardage of piece e.g. 100 yard piece got 70 penalty points.
Second Quality:
Fabric is considered second quality it total penalty points exceed total yardage of fabric.
