The "4 Point System" is a fabric inspection method used in the textile industry to assess the quality of fabric defects. It involves assigning points to defects found in a fabric sample, with higher points indicating more severe defects. The total points are then used to determine the fabric's overall quality. Here's a basic formula for the 4 Point System fabric inspection:

Defects Identification: Inspectors identify and categorize defects in the fabric sample. Common defects include knots, slubs, holes, stains, snags, or irregularities in the weave or printing.

Point Assignment: Each defect is assigned a point value based on its severity or size. The severity of defects and the corresponding point values may vary depending on industry standards and specifications.

For example, a small knot might be assigned 1 point, a larger knot 2 points, and a hole might be assigned 4 points.
Total Points Calculation: The total points for all defects found in the fabric sample are calculated by summing up the points assigned to each defect.

Quality Assessment: The total points are compared against a predetermined threshold or standard to assess the overall quality of the fabric. If the total points exceed the acceptable limit, the fabric may be deemed unacceptable for use or may require further inspection or remediation.

Reporting: A detailed inspection report is generated, documenting the types and quantities of defects found, as well as the total points assigned. This report is often used for quality control purposes and may be shared with fabric suppliers, manufacturers, or customers.
