CTT - Entanglement Tester

INTRODUCTION

The entanglements are responsible for holding the filaments together during the fabric formation so we can work with the yarn. The most important characteristics of the entanglements are the count, uniformity and strength of the entanglements.

CTT with Accu-Count Entanglement software, ACE offers entanglement analysis based on dynamic yarn diameter measurements. A CCD camera is used to measure the yarn diameter values with 3.25micron precision when the yarn is moving at speeds up to 360m/min.

As the yarn passes in front of the camera, the ACE software counts the entanglements and searches for the missing ones in the yarn. The ACE report includes the number of entanglements per meter, standard variation and coefficient of variation as well as the maximum skip (no show length) and the skip count. Accept/Reject limits can be defined by the operator.

The test results and the diameter graphs are saved in common file formats. The profile of any individual package or the entire test can be viewed at any time. This unique feature provides the ability to look at the entanglements and verify how the entanglements are counted, which is not possible with any other entanglement counting system in the market.

The entanglement strength test is done by gradually increasing the tension on the yarn until most of the entanglements are gone. Alternatively, the test can be setup to find the tension level that is required to remove certain percentage of entanglements.

Operation

High speed production testing, continuous testing, and entanglement strength (integrity) tests are offered. Also, the yarn's elongation at the test tension is reported.

Package changer available as well as other CTT test options.
