The FIBROTEST combines fibre length measurement and fibre strength test on fibre bundles within one instrument. The two measurements are executed in succession on the same sample. After completing these measurements, the sample mass is automatically determined. This enables the calculation of the exact and absolute value of the tenacity.
PT. Kawan Era Baru is the sole distributor in Indonesia for all Textechno’s products.
“Operation of the FIBROTEST does not require calibration cotton and is, therefore, independent of any influences from this side. Nevertheless the system can be calibrated with calibration cotton to duplicate the results from high-volume testers.”
Key fibre characteristics of cotton
Fibre length and breaking strength determine to a large extent the processing of cotton fibres into yarns and the properties of the yarn itself.
Fibre length is usually measured on a bundle of fibres according to the Fibrograph system. This test is based on an optical scanning device and delivers various parameters characterizing the fibre length distribution.
Fibre strength on cotton fibres can be measured on fibre bundles. As the fibre bundle strength depends on the number of fibres in the bundle, precise measurement of tenacity requires measuring of the tensile forces as well as the mass of the fibres between the clamps with high accuracy.
Present testing instruments are either purely manually-operated devices for each of the two test methods, or fully automatic high-volume test stations. The latter employ measuring systems which have to be calibrated using so-called calibration cotton. For this reason all measured results depend on the data of the calibration cotton as specified by its supplier. They are not directly traceable to physical base units.

Sample preparation station
Use of the tester is simple and straightforward: The operator prepares the sample with a comb-type sample holder. Unavoidable fibre mass variation along the sample holder is – different from conventional testers – compensated by the FIBROTEST optical system with high lateral resolution. After inserting the sample holder into the tester all test functions are executed in a fully automatic way.
Control of the test process as well as measured data evaluation featuring printout of individual values and their statistical analysis is provided by the Textechno TESTCONTROL system, consisting of a PC and Textechno software.
