Buttonhole Selvage — This defect is the result of tension build up in the shuttle. It can be caused by several things: a crooked bobbin, bobbins not ringing properly, placing the tip of the bobbin too close to the shuttle eye, waste restrictions in the eye of the shuttle. The taut filling, pulling the selvage toward the body of the fabric, results in shed-splitting near the edge of the fabric. This defect may occur in isolated instances or continuously with the running out of each bobbin depending upon the cause.
