ATTRIFIL III | 233C

Computerised instrument for automatic measurement of the friction coefficient of yarns. Recommended for wax or paraffin evaluation and control of the waxing process.

Attrifil III 233C

Main features

Automatic execution of multiple tests on a single package of yarn without operator attendance.
Continuous control of test parameters affecting the friction coefficient, such as input pretension (value and tolerance) and yarn speed, which can be adjusted by the operator up to 50 cN and from 50 to 300 m/min.
High-precision electronic tensiometers to monitor the incoming (T1) and outgoing (T2) yarn tension before and after the yarn has run around the metallic friction pin, reaching 180° wrapping angle, in compliance with the test method
Pre-selection of the yarn length to be measured.
Pre-selection of the yarn length between two consecutive measurements as an alternative to random testing.
Software for equipment management (parameter settings) and for data processing and storage.
Print-out of test results, statistics, graphical representation of single test coefficient of friction, and average value.
