Yarn Twist Tester
1. Product Introduction & Applications
The Yarn Twist Tester is a precision instrument designed for determining skein length, yarn twist characteristics, and linear density of various textile yarns. With a manual high-accuracy measuring mechanism and adjustable loading system, it provides consistent and reliable results across different yarn types, including wool yarns, synthetic fibers, blended yarns, sewing threads, and knitted fabric yarns.
Key Applications
Textile Production
Ensures yarn skein length, twist stability, and linear density meet manufacturing specifications for wool, filament, and blended yarns.
Quality Inspection & Laboratory Testing
Widely used in QC departments and textile testing labs to verify yarn number, tension uniformity, and physical properties.
Research & Development
Supports yarn structure analysis, performance studies, and comparative research on twist influence and deformation behavior.
Product Highlights
High-precision manual measurement with 0.1 cm resolution
Adjustable loading weights for various yarn types
Corrosion-resistant SUS304 stainless steel counterweights
Compact, bench-top design suitable for laboratory environments
Easy to operate and low maintenance vs. automated systems
