About This Product
Twist is the number of turns given to a yarn per unit length, and it affects the strength, appearance and feel of the yarn. In a twist test, a length of yarn is held between a fixed clamp and a rotating clamp, and the rotating clamp is turned to remove the twist while the counter records the number of turns. The test length is set on a scale, so turns per inch or per metre can be worked out. A needle is used to confirm that all twist has been removed, and a magnifying glass helps in seeing the end point. The Twist Tester can be supplied for export orders from Bangladesh, Italy, Grenada, Botswana, Montenegro and Kazakhstan.
