Yarn Twist Tester
The Yarn Twist Tester is a precision instrument designed to measure the twist of various types of yarns and evaluate their related technical parameters. It is widely used in textile laboratories, quality control, and research and development to ensure the performance and consistency of yarns for knitting, weaving, and industrial applications. The instrument supports multiple test methods and provides accurate data output for analysis.
Applications
(1) Quality control in yarn manufacturing, including single yarns, ply yarns, cotton, wool, silk, and synthetic fibers.
(2) Research and development of new yarn types for knitting, weaving, and industrial textile products.
(3) Laboratory testing for yarns used in fabrics, carpets, and technical textiles.
(4) Evaluation of yarn characteristics for sewing threads, embroidery threads, and high-performance industrial yarns.
(5) Testing yarns for sportswear, home textiles, and medical textiles to ensure consistent twist and performance.
(6) Educational and research purposes in textile engineering programs and laboratories.
Standards
(1) GB/T 2543.1 – Textiles: Determination of Yarn Twist, Part 1: Direct Counting Method
(2) GB/T 2543.2 – Textiles: Determination of Yarn Twist, Part 2: Untwist-Retwist Method
(3) ISO 2061 – Textiles: Determination of Yarn Twist, Direct Counting Method
(4) ISO/DIS 17202 – Textiles: Determination of Yarn Twist (subject to updates; confirm latest version before use)
(5) BS 2085 – Relevant clauses regarding yarn twist measurement in British Standards
(6) ASTM D 1422 – Standard Test Method for Yarn Twist (ASTM)
(7) ASTM D 1423 – Standard Test Method for Yarn Twist (ASTM)
Features
(1) Supports multiple test methods including direct counting, single untwist-retwist, double untwist-retwist, and triple untwist-retwist.
(2) Wide twist measurement range suitable for various yarns and ply yarns.
(3) Adjustable yarn tension with a set of weights to accommodate different yarn types.
(4) Continuously adjustable rotational speed of the chuck or holder to meet different test requirements.
(5) Arbitrary test length settings to comply with multiple standards and yarn specifications.
(6) Touch screen or LCD display for real-time data visualization.
(7) Print output in Chinese or English for test reports.
(8) AC 220V 50Hz power supply, with voltage and frequency customizable depending on the model.
