Fibre Fabric Testing


Field of Application for Itru Fibre Tester UAK-1+ and Testing Operation

Itru Fibre Tester UAK-1 + is an innovative measurement and evaluation system based on the image processing and analysing .With UAK-1 + Color matching analyses of dyed and undyed samples of fabrics could be carried out in addition to measurement and analysing of length,color,neps ,contamination of waste, material and sliver .-

With UAK- 1+
-Diameters of wool fibres in microns
-Picks per cm or ends/per cm of fabrics
-Courses/cm and wales/cm of knitted fabrics
-Fabric Porosity % of fabrics
-% of Fibres in blends
-% of white specks measured under UV-light
-% of fibres in Yarn-X-section
-Black Neps in melange fabrics
-Neps in dyed fabrics could also be measured, analysed and evaluated.

Testing Operation

Beard Test:

Test Material is placed upon the Feed Unit. Start1 button actuates the Feeding Unit which in turn feeds the material to the Measuring Clamping Head. Fibres are straightened ,brushed by special system and at the same time Feed Unit is cleaned automatically. Clamped Fibres which are ready for measurement in the Measuring Head move underneath the Image Capturer. The operator saves the captured image to the computer .and Press Start 2 button . Measuring Head moves further and fibres in clamped head automatically cleaned and returns to original starting position for commencing next test. All these sequences of movements are completed within a 25 seconds.

Surface Test :

The material is placed in the reserved Box . Scan button as pressed which actuates cover plate to move down and which in turn covers the material to be tested. The operator saves the image on the screen of the monitor.

After these two tests operators get either single detailed or summary reports.

UAK-1 is a fully automatic,rapid ,only and the first Fibre/Sliver/Waste/Fabric measurement , evaluation information system in the world. Thanks to its fibre feed system that can measure slivers in both directions (leading and trailing) without distorting the slivers and breaking the fibres before the measurement takes place . UAK-1+ which measure fibers in several points in processing and can be used to improve spinning performance, reduce waste, identify off-standard running processes and machinery. and yarn quality (Fiber/Sliver/Spinning Technology Information system).

Itru Fibre Tester UAK-1+ comprises a very detailed Fibre/Sliver/Waste Analyser information and New Fibre Processing Techniques for short and long staple spinning. UAK-1+ has been developed as a result of many years of hard research works and finding solutions to the mill problems.

It is very clear that the mills who make use of UAK-1+ will gather more information to improve their mill performance to a higher level than they actually have now

Measured and computed parameters are more than 70 and the charts provided are more than 10. The application make using of all these parameters and charts will come into light in future more and more. We let you to decide to make comparison and the fields of application of UAK-1 to end user.

Our Testing Services is available for the testing parameters mentioned above. If you like to have test your samples please get in touch with us for further information.
