 Accurate measurement of Interlace level in all filament yarn processes is critical, yet laboratory techniques have major shortcomings, in both the statistical significance of the data and the lag time between manufacturing and testing.
The MicroSCAN provides a revolution in Interlace measurement by providing an at line technique for accurate measurement of both:
- Mean Interlace Level
- Short Term Interlace Variation
Historically at line measurements have been considered to be less accurate than laboratory tests, but the MicroSCAN has been shown in production tests to be MORE ACCURATE than laboratory tests in measuring mean Interlace level, with the additional benefit of providing excellent data on variability due to the increased sample lengths.
As a result, the MicroScan offers substantial benefits in comparison to Laboratory testing:
Faster Feed Back with immediate identification of faulty threadlines
Statistically accurate data, due to extend test lengths and accuracy of measurement
Lower Testing Costs with only a few seconds for a measurement a single technician can realistically test well over 100 threadlines per hour using the MicroScan
Much Lower Capital Costs, a single MicroScan has substantially greater measurement capacity than any Laboratory tester yet is a fraction of the cost
As a result of these benefits, using theMicroSCAN for Interlace Measurement provides:
- Reduced Off Quality
- Improved Downstream Process Performance
- Reduced process costs, due to better control of the process
- MicroScan - Method of Measurement
Interlace measurements are made using the MicroScan together with the FS220 or FS230 Optical Probes. The probes operate by shadowing the running threadline against a photo sensor. Interlace is measured by using signal recognition technology (patented) to identify the Interlace nodes in the yarn accurately and at the same time ignore the effects of twist and tension changes that affect other measurement systems.
The result is a very accurate Interlace measurement system that will operate at very high speeds - to over 7,000 m/min. The FS220 Operates over a titre range of 10 to 2,000 denier, and the FS230 from 500 to 12,000 denier.
For each measurement the Mean, and CV of the Interlace level, together with the Maximum Distance between nodes and the CV of distance between nodes are calculated and stored in non volatile memory on the MicroSCAN, data can then be viewed and printed
