Testing and evaluation of a wide range of fibre properties are essential for research and quality control purposes in fibre production and for assessing the processability of fibres in carding and spinning. For man-made fibres and in some cases even for natural fibres these tests are carried out on single fibres. Here, typical testing methods are the static tensile test, linear-density (fineness) measurement, and measurement of crimp extension, crimp stability as well as number of crimps.
FAVIMAT+ can test the following fibre properties
on the single fibre:
– Linear density (even on stiff fibres)
– Tensile properties (including elastic properties, creep, and elongation)
– Geometrical crimp properties (3D-crimp measurement in preparation)
– Mechanical crimp properties (including crimp stability)
– Bending stiffness (two test methods, one including fatigue tests)
– Fibre-to-metal friction
The design of the FAVIMAT+ takes into account any needs to combine single-fibre linear-density measurements and tensile tests with different crimp test methods into a single testing instrument. All of these tests are carried out on the same fibre section. Transferring the fibre from one testing device to another is, therefore, no longer necessary.
Clamping systems for different fibre types:
The FAVIMAT+ standard clamps are suited for all textile- and most technical fibres including glass, carbon, basalt and Aramid. For very short samples special clamps with jaw faces of only 2 mm height
and an innovative short fibre insertion mode enable tensile tests of short cut fibres up to minimum lengths of 3 mm. An optional pressure amplifier is recommended for high-tenacity material like
Polyvinyl alcohol (PVA) as used in concrete reenforcement.
A further special clamp for manual sample insertion is equipped with force reduction bollards in order to avoid slippage between the jaw faces or breaks at the clamps on testing very critical material such as ultrahigh molecular weight Polyethylene (e.g.
Dyneema, Spectra). For such applications a highresolution load cell with a force range of 1.200 cN is available.
ROBOT2 comprises a sample storage unit and a transfer clamp,
the latter for transferring the single fibre from the storage unit to the test section, and a suction system for removing the waste fibres after each test. The sample storage unit contains up to 20
magazines, each of which can accommodate 25 individual fibres. Therefore, the total capacity of the unit amounts to 500 fibres.
The AIROBOT2 is a variant of the ROBOT2 automatic fibre feed unit. Here the fibres are loaded pneumatically into the magazine in a semi-automatic loading unit.
FAVIMAT+ AUTOFEED, is the first fully automatic single-fibre tester, to which the fibre sample is fed as a flock. A fibre magazine collects up to 20 flocks in separate containers. These flocks can be of the same or of different fibre types. AUTOFEED automatically takes out individual fibres from a specified container and feeds them one by one to the FAVIMAT+ testing instrument.
