Statimat DS automatic evenness-, count-, and tensile tester for spun yarns.
Represents the most integrated testing solution for tenacity, count, and evenness in one instrument.
Fits the needs of both the spinning- and yarn processing industry, such as weaving or knitting.
High degree of automation guarantees a fast return of investment.
Three tests on each package presented by the package changer for 24 yarn ends are performed in succession without operator interference.
Test report contains all individual results as well as a statistical evaluation of all yarn parameters including thin places, thick places, and neps.
Test results are well comparable with all commonly known cotton statistic compilations.
Application range can be extended by using interchangeable load cells with a force-measuring range up to 1.000 N as well as other sample holders for tensile tests on fabrics, yarn skeins for lea tests, adhesion force tests on slivers and rovings, and other sample forms.
In combination with covaslive stand-alone instrument, represents a complete laboratory for tops, slivers, rovings, and yarns.
Test Methods
Tensile Test
High clamping force of the pneumatic jaws for tensile tests up to 1000 N.
Long path of the draw-off clamp for breaking extensions up to 1000 %.
Quick yarn threading reducing idle time between successive tests to only a few seconds.
Force-measuring system within the force range of 1000 N (1500 N on request).
High variability of the test process and the evaluation of the measured data.
In addition to the static tensile test (e.g. according to ISO 2062 or ASTM D2256, D885), alternating load tests (hysteresis tests) are possible according to freely selectable programs, as well as creep and relaxation tests.
Yarn feeding device enables high-speed take-off of selected yarn lengths prior to starting the test on a new package or between successive tests on the same package.
Tests can be carried out on yarn lengths both from the package outer and inner layers.
Beside the standard automatic yarn clamps, various special clamps for manual introduction of the test sample are available.
Special clamps enable tensile- and elasticity tests on fabrics and cohesion tests on slivers or rovings.
Yarn Evenness Test
New innovative capacitor system enables capacitive testing of the mass unevenness according to ISO 16549 within a wide yarn count range by individual adaptation of the measuring sensor to the properties of the yarn material.
Yarn tension can be monitored in order to ensure proper testing conditions.
Measurable variables delivered by the system are the coefficient of variation of the mass distribution along the yarn length, the spectrogram, and for staple fibre spun yarns the numbers of neps, thick and thin places.
Yarn Count Test
Test according to ISO 2060 or ASTM D6587.
A preselected yarn length, e.g. 100 m, is delivered by the yarn feeding device into a collection chamber, and subsequently the weight is measured.
By using the principle of a vacuum conveyer the yarn is permanently in contact with the ambient (laboratory) climate, avoiding drying of the yarn as would occur with a compressed-air system.
Yarn tension measurement during the test; if tension limits specified by the relevant standards are exceeded, a correction is automatically made based on the same yarn's tensile properties.
