Skein Length Tester
The Skein Length Tester is a precision instrument designed to measure the length of yarn accurately. It is used for determining yarn linear density (yarn count), yarn strength testing, and evaluating yarn uniformity. The tester employs microcontroller control for smooth, reliable operation, with real-time speed monitoring and adjustable parameters to ensure reproducibility and precision.
Application
The tester is widely used in:
(1) Textile and yarn manufacturing: determining yarn count and linear density
(2) Quality control laboratories: verifying yarn consistency and strength
(3) R&D in textile engineering: testing new yarns or blends
(4) Sewing thread production: evaluating standard compliance of threads
(5) Educational and research institutions: yarn property analysis and training
Standards
GB/T 4743: Textiles – Yarn from packages – Determination of linear density by the skein method
GB/T 14343: Testing method for linear density of synthetic filament yarns
GB/T 6838: Testing method for sewing threads
ISO 2060: Textiles – Yarn from packages – Determination of linear density by skein method
ASTM D1907: Standard Test Method for Linear Density of Yarn (Yarn Number) by the Skein Method
Product Features
(1) Microcontroller control: True single-chip digital control with smooth start/stop and real-time speed measurement
(2) Adjustable stopping laps: Can pre-set 1–5 laps for deceleration to prevent yarn tangling or punching
(3) Continuous variable speed: Adjustable yarn frame speed from 30–260 r/min
(4) Electronic counting and display: LED or LCD display for loop count, speed, and tension
(5) Safety and stability: Emergency stop switch, dust cover option, firm stainless steel and aluminum alloy frame
(6) Pre-tension device: Improves accuracy during testing
(7) Multi-tube testing: Supports up to 6 yarns simultaneously
