Manual Yarn Twist Tester is mainly used to test the twist, uneven twist rate, shrinkage rate, etc. of various yarns. The twist of the yarn can be measured by hand-cranked transmission.
The twist of the yarn is measured by hand-cranked transmission, that is, the twist number per unit length of the yarn is measured, the minimum twist index: 1/10 twist, test length range: 0-300mm.
First clamp a certain length of yarn, determine the twist direction, and then start to untwist it by hand, read the values on the handle scale and the counting disk, and calculate the twist value per meter.
This instrument is used to measure the twist number of various yarns such as cotton, wool, linen, silk, etc. within a certain length to assess product quality and correct problems in the production process.
