“Yarn strength” indicates the amount of tensile load the yarn can withstand. It is classified as absolute yarn strength and relative yarn strength. Relative yarn strength is used when comparing the strength of a yarn with respect to another one.
Automatic Single Yarn Strength Tester, to determine the breaking strength and elongation rate of single yarn made of cotton, wool and others up to 6000cN, with air-driven clamps. Fully automatically test up to 20 cops at the same time.
ASTM D2256，ISO 2062GB/T 398，GB 5324，GB/T 14344，BS，JIS，AS，CAN/CGSB
