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.
