Electronic Yarn Twist Tester

Application

Electronic Yarn Twist Tester is used to determine yarn twist in single or plied yarns, quadrant type with auto stop & reverse for conventional or untwist/re-twist methods. Test length adjustable up to 50cm/20 inches for S & Z twist yarns.

Features

• Determine the twist of single or twisted (Single & multiple) and OE yarns.
• Three methods available to be selected by the operator: Traditional “untwist/ retwist method for single yarns.
• “Schutz” method (untwist, retwist and double countercheck) for OE yarns, worsted and slippery yarns.
• Direct “untwist” method for plied yarns, threads and multifilament yarns.
• Direct TPI, TPM and TM results in digital display.
• Silent and integrated motor operation with auto-stop and counting control system for precise measurement.

Why Choose the Electronic Yarn Twist Tester?

The Electronic Yarn Twist Tester offers unmatched precision and versatility for yarn twist measurement. It accommodates single, plied, and OE yarns, providing multiple testing methods: traditional untwist/re-twist, Schutz method for slippery or worsted yarns, and direct untwist for plied or multifilament yarns. Its digital dot-matrix display delivers TPI, TPM, and TM results instantly, while the auto-stop and reverse function ensures accuracy and protects yarn samples. The microcomputer-based control system allows programmable parameters including measurement units, sample length, twist direction, and speed index. Adjustable tension and elongation settings further improve measurement consistency. Compliant with ASTM D1422/D1423 and IS 832 standards, it is ideal for textile labs and production facilities aiming for precise, repeatable, and efficient yarn twist evaluation.
