Fabric defect · Woven fabric - Mispicks, broken picks and double picks

ConductVision Textile is designed to flag each defect with its place on the roll, its size, its points and a still image. Your inspector names the defect and confirms or dismisses it.

On the defect map in the roll report, a mispick is a line across the width.

A U.S. federal glossary of fabric imperfections groups these as misweaves in the filling direction. A mispick is "a pick woven in improper order," a broken or missing pick is "a pick wholly or partially missing," and a double pick is "two or more picks in the same shed across the full width of the cloth" ¹.

A crack, or shirer, is close kin: "an open streak parallel with the filling and extending partly or entirely across the cloth" ¹. With light behind the fabric, a missing pick or a crack can show as a bright line. Goldberg photographs thin spots from broken filling yarns this way, by transmitted light ².

A mispick or a broken pick is a line across the width at one place along the roll, across all of it or part of it ¹. A crack, too, can run partly or entirely across the cloth ¹.

A mispick across the full width is longer than 9 inches, so it scores 4 points, and no linear yard scores more than 4 ³. A partial pick is scored by its length on the same scale, from 1 point up ³.
