CTT - Dynamic Tensile Tester
INTRODUCTION
The CTT Dynamic Tensile Strength Test is designed to simulate the stress on the yarn during textile manufacturing. Also known as Weak Spot test, this test is used to check the “local” strength of the yarn to see if the yarn will survive the dynamic tensions that are created during winding, weaving or spinning.
Conventional static tensile testers measure breaking strength and breaking elongation of the yarn. The CTT measures if a yarn can withstand a specific tension level as it is moving. This is the true yarn performance test to check the yarn survivability during manufacturing.
The cost of yarn breakages causes productivity loss, thus increasing the manufacturing costs. An improvement in material quality and production efficiency is the result by testing possible yarn breakage before the yarn is used in production.
During the CTT weak spot test, the instrument applies a selectable yarn tension between 1g and 700g at a variable speed up to 360m/min. This enables continuous measurements of more than 21 km of yarn in one hour, which will lead to early detection of the yarns that have weak spots before they enter the production.
