A professional who determines physical properties of greige and finished cloth, employing standardized tests, equipment, and procedure. Responsibilities include:

• Measures width of cloth with ruler.
• Guides electric knife along markings on cloth to cut fabric samples for testing.
• Weighs sample on grain scales and converts grain weight into desired units, using mathematical tables.
• Counts number of warp and filling per unit space, using pick counter.
• Positions cloth sample between jaws of testing machine and moves machine controls to apply force necessary to rupture sample and determine tensile strength of cloth.
• Sews across sample, using portable sewing machine, and examines stitching through magnifying lens to detect threads broken by sewing machine needle.
• Creases sample under controlled conditions and places sample in clamp on crease recovery tester to determine cloth resiliency to creasing.
• Records test results and reports variation from standards to manager, quality control.
• In addition, may perform other tests, such as tear test, crimp test, fabric bow test, abrasion test, bursting test, heat transmission test, permeability test, and water repellency test.
