              1, the general method: temperature for 21±1℃, humidity 65±2%, check the twist tester, to ensure accuracy, testing requirements. Test the record value and determine the sample type. (D1059 or D1907)

              2, staple, with moving clips to get the proper little and common length, cotton spinning accuracy of 15, 20 or 25mm, worsted wool precision 25 or 50mm. The tension is 0.25±0.05cn/tex hanging yarn When the twist can not change. The length of the clip is not more than 25mm, and can be turned back by rotating a movable clip until the yarn is parallel. To judge with the eye or with a needle from one clip to another. Record twist, initial length, twist, repeat, until all samples are tested.

              3, filament monofilament: Clip distance 250±0.5mm, tension 0.25±0.05cn/tex, Precision 0.5mm records the initial length, the twist can not be changed when hanging yarn. The length of the clip is not more than 25mm, and can be turned back by rotating a movable clip until the yarn is parallel. To judge with the eye or with a needle from one clip to another. Record twist, initial length, twist, repeat until all samples are tested (the back twist will cause length to be lengthened, so be ready to move the clips.) )

              4.using the above method to determine the twist, remove the tension, remove the excess part to obtain the final length. To make sure that the yarn in it has the same twist and twist, if you don't know, prove it. If not, each yarn is tested and reported separately. (minus part of the twist can not change, some words will cause the sample twist also changed.) ). The twist cannot be changed. Single yarn To adjust the tension, 0.25 ± 0. $number Cn/tex.Twisted Yarn

              5, single yarn and composite wire strands of the strand use the above method to judge the twist, remove the tension, remove the excess part to obtain the final length. To make sure that the yarn in it has the same twist and twist, if you don't know, prove it. If not, each yarn is tested and reported separately. (minus part of the twist can not change, some words will cause the sample twist also changed.) ). The twist cannot be changed.

               6, the final twist to determine longer than the length of the test, so that there is no tension and clamping, minus the close to the clip, and do not test the twist of the part, slowly remove the part of the no clamping, and then test.Twisted Yarn
