Optical Yarn Evenness and Hairiness Tester (OPTIYARN OPT01)
Optik İplik Düzgünsüzlük ve Tüylülük Test Cihazı (OPTIYARN OPT01)
Optical diameter measurement at 0.5 mm intervals along the yarn; evenness (U%, CV%, SD), hairiness and filament anomaly analysis at 20–300 m/min. Spectrogram and periodic fault evaluation; statistics, PDF test reports and CSV data export in the external PC software.
Model technical data
- Measuring speed: 20–300 m/min.
- Measuring interval: 0.5 mm along the yarn.
- Diameter and evenness: optical yarn diameter; U%, CV% and SD from the optical diameter signal.
- Surface analysis: yarn hairiness and filament anomalies.
- Periodic analysis: spectrogram and periodic fault evaluation.
- Software and outputs: external PC software; PDF test reports and CSV data export.
- Method references: ASTM D5647 (photo-electric yarn hairiness guide), ISO 139 (conditioning and testing atmosphere), ASTM D2258 (yarn sampling).
- Evenness statistics are calculated from optical diameter data.

Dimension order and approximate values are stated in each row. Packaging data are separate from instrument dimensions and net mass. Approx. rows are preliminary engineering estimates based on comparable equipment and function/capacity; they are not verified manufacturing measurements or standard requirements. Installation and shipment are finalised against the approved drawing and nameplate. Estimate scope: base product / one unit; external computer, bench and auxiliary plant excluded.
Specifications, dimensions, and power requirements are approximate and subject to change without prior notice for continuous design improvements.
Product technical specifications and images may vary according to manufacturing conditions and applicable standards.
Test and configuration
- Measured output / function
- Optical diameter evenness (U%, CV%, SD), hairiness and filament anomalies
- Parameters selected for the method
- Measuring speed, test length, measuring interval and conditioning
- Verification points
- Optical measuring channel, feed speed and reference specimen
Listed methods are application references. Suitability is established by assessing the selected hardware, current method and calibration together.
Control and recording specification
The following are method-specific software/recording requirements; delivered software modules are defined by the order scope.
- Method code and edition, specimen ID, operator and selected test parameters are linked to the record.
- The optical diameter signal, measuring interval, speed and test length are stored together with U%, CV%, SD, hairiness and spectrogram results.
- Raw measurements, units, valid/invalid test flags and the reported result remain traceable.
- Calculations are checked against known inputs and an independent calculation; sensor channels are checked against calibration values.
Test standards
- ASTM D5647 Standard Guide for Measuring Hairiness of Yarns by the Photo-Electric Apparatus
- ISO 139 Textiles — Standard atmospheres for conditioning and testing
- ASTM D2258 Standard Practice for Sampling Yarn for Testing
