The Strip Evenness Tester is a high-performance textile laboratory instrument designed to analyze the density and uniformity of fine yarn, roving, and sliver. It provides precise detection of unevenness in cotton, wool, hemp, chemical fiber short fibers, and blended yarns. This instrument enables detailed analysis of the causes of unevenness, offering valuable insights for quality control and production optimization.
The Strip Evenness Tester is suitable for:
(1) Cotton Industry: Testing yarn, roving, and sliver for CV%, U%, thick/thin places, and neps.
(2) Wool Processing: Evaluating short fiber uniformity in wool and blended yarns.
(3) Chemical Fiber Production: Monitoring the consistency of synthetic fibers, including polyester, nylon, and viscose.
(4) Textile Laboratories: Quality control of spun, blended, or pure fiber yarns.
(5) Extended Applications: Can also be applied to research in fiber blending optimization, automated production line monitoring, and textile defect analysis.
(6)Specific products tested include: cotton yarn, wool yarn, hemp yarn, polyester yarn, viscose yarn, blended fiber yarns, roving, and slivers.
The Strip Evenness Tester aligns with common textile testing standards, including:
(1) ISO 2060:1995 – Textiles – Determination of linear density of yarns (Tex system)
(2) ISO 1833-1:2020 – Textiles – Quantitative chemical analysis of fiber mixtures
(3) ASTM D1425 – Standard Test Method for Evenness of Yarn
(4) GB/T 3811-2010 – Testing of fiber and yarn uniformity
(1) High Precision Measurement: Sensitive capacitance sensors detect minute mass variations in textile strands.
(2) Wide Material Range: Supports cotton, wool, hemp, synthetic, and blended yarns.
(3) Comprehensive Analysis: Provides CV%, U%, imperfections, spectrograms, vari-length curves, and linear density distribution.
(4) High-Speed Testing: Capable of up to 800 m/min for rapid production monitoring.
(5) Automated Operation: Features automatic yarn feeding, zero adjustment, and defect alarms.
(6) Expert Analysis Software: Integrated software for root cause diagnosis and corrective action suggestions.
(7) User-Friendly Interface: Windows-based graphical interface for intuitive operation and visualization.
(8) Data Management: Stores, replays, and prints test data for long-term analysis.
