Reed Marks and Starting Marks Read Back to the Loom
Greige reed marks and starting marks map directly to reed wire spacing and loom stoppage dynamics, requiring electronic let-off adjustment to eliminate defects.
Optical Thread Counter
Fabric Analyzer
Automated testing instruments that use digital imaging and optical sensors determine the density of warp and weft yarns in woven textiles. Quality control laboratories use an optical thread counter to verify the construction of woven linen fabrics without destroying the samples. The device scans the fabric surface and counts the individual yarns per unit of measurement.
This automated process replaces manual counting with a magnifying glass, which reduces operator error.
Measurement Method
The instrument operates by capturing a high-resolution digital image of the fabric sample under controlled lighting conditions. Software algorithms analyze the image, identifying the peaks and troughs in the light intensity profile that correspond to the yarn crossings. This system calculates the thread count in both the warp and weft directions within seconds.
Accurate measurements are crucial for linen fabrics, where natural variations in yarn diameter can make manual counting difficult. The digital records generated by this device provide objective proof of fabric density for quality compliance certificates.
Standard Compliance
Verifying the thread count ensures that the delivered fabric meets the buyer’s specification limits. If the density falls below the contract terms, the fabric may have lower tear strength and a coarser texture. This automated verification maintains the integrity of the mill’s quality assurance process.
