Description

The Yarn Twist Testing Machine is a high-precision laboratory instrument used to determine the twist per unit length in single, doubled, or plied yarns. Twist directly affects yarn strength, elasticity, appearance, and fabric performance — making this machine essential for spinning mills, textile manufacturers, and quality control laboratories.

This machine operates on the untwist–retwist or direct twist counting method, depending on yarn type and testing standards. It features accurate tension adjustment, a smooth rotation mechanism, and a digital counter or display for precise readings of twist per inch (TPI) or twist per meter (TPM).

Designed for efficiency and reliability, the Yarn Twist Testing Machine is built with a durable metal frame, high-quality clamps, and variable-speed motorized operation (optional manual mode). It complies with international textile standards including ASTM D1422, ASTM D1423, ISO 2061, and BS 2085, ensuring standardized, repeatable results.

Key Features:

• Measures twist in single, doubled, or plied yarns

• Available in manual, semi-automatic, and digital models

• Adjustable tension and speed for various yarn types

• High-precision digital or mechanical counter

• Conforms to ASTM, ISO, and BS testing standards

Applications:
Perfect for spinning units, textile research labs, and yarn manufacturers to evaluate yarn twist, uniformity, and quality, ensuring superior performance and consistency in finished fabrics.
