Yarn Twist Tester

The Yarn Twist Tester is a precision instrument designed to measure the twist level and twist direction of yarns. It is widely used in textile testing laboratories and production quality control to evaluate yarn structure and performance, ensuring compliance with relevant testing standards.

Application

Textile Manufacturing: Ensures skein length meets specifications for wool, blended yarns, and knitted fabrics.

Quality Inspection: Used by labs and certification bodies to validate product standards.

R&D: Supports material innovation by assessing yarn twist and structural integrity.

Product Advantages

High Precision: Manual control with 0.1 cm scale accuracy for reliable length measurement.

Versatile Loading: Adjustable counterweights (300g/500g/1500g) suit diverse yarn densities.

Durable Construction: SUS304 stainless steel weights resist corrosion.

Easy Operation: Blade-shaped hanging plates ensure even sample spreading.

Compact Design: Portable size (350×600×150 mm) and 35 kg weight for lab flexibility.

Cost-Effective: Manual control reduces maintenance vs. automated systems.

Product Features

Blade-Shaped Hanging Plates: Secure upper/lower sample ends for stable tension.

Lever-Type Pressure: Applies consistent force via 19mm diameter rollers.

Adjustable Counterweights: 2.4kg/3.0kg/6.0kg options (incl. lower plate deadweight).

Roller System: Upper/lower rollers (19mmØ) ensure smooth yarn unwind.

Length Calculation: Formula A=(L-πd)/2 (A: Roller center distance; L: Skein length; d: Roller diameter).

Real-Time Reading: Scale records deformation within 30 seconds for quick validation.
