The Yarn Loop Length Tester is a precision instrument designed to measure the loop length of various yarns and knitted loops. It is widely used in textile laboratories and quality control to verify compliance of different yarn densities and counts with standard loop lengths. The tester ensures accurate and consistent measurements under specified tension, supporting yarn development and production evaluation.
Applications
(1) Determining loop length of single and ply yarns in textile manufacturing, including cotton, wool, silk, and synthetic fibers.
(2) Evaluating knitted loops for fabrics used in apparel, home textiles, and industrial applications.
(3) Quality control in yarn processing plants to verify conformity with loop length standards.
(4) Research and development for designing yarns with specific density, elasticity, and loop properties.
(5) Testing yarns for sewing threads, embroidery threads, and technical textiles.
(6) Educational and research purposes in textile engineering programs and laboratories.
Standards
(1) FZ/T 70001-2003 – Textiles: Yarn Loop Length Determination Standard
(2) FZ/T 71004-2003 – Textiles: Standard for Loop Length Verification of Various Yarn Densities
Features
(1) Column fixed to base supporting upper sleeve, scale, and serving as lower sleeve guide.
(2) Rollers installed on both sleeves for precise yarn positioning.
(3) Upper sleeve position adjustable via vertical axis to accommodate different loop lengths.
(4) Lever mechanism applies tension through selectable weights according to yarn specifications.
(5) Pointer indication enables accurate loop length measurement with 0.1 cm precision.
(6) Capable of measuring loop lengths of yarns under specified tension with rapid stabilization.
