Fiber Blend Ratio Tester
Category：Fabric & Textile Tester
Introduction
The Fiber Blend Ratio Tester is designed to measure the electrical resistance of a compacted fiber sample and convert it into the specific resistance of the fiber according to its filling density. It provides accurate, repeatable measurements for fiber quality evaluation, research, and production control, suitable for textile, nonwoven, and fiber material laboratories.
Application
(1) Testing specific resistance of synthetic staple fibers such as polyester, rayon, acrylic, and nylon in textile manufacturing.
(2) Quality control and R&D of fiber blends in nonwoven fabrics, yarns, and felts.
(3) Evaluation of cotton, wool, and blended natural fibers for electrical properties.
(4) Measurement of resistance in technical textiles used in automotive, aerospace, and medical applications.
(5) Assessment of fiber-based materials for smart textiles, conductive fibers, and anti-static fabrics.
(6) Comparative analysis of recycled fibers or fiber mixtures for product development.
Standards
(1) GB/T 14342-1993: Synthetic short fiber specific resistance test method.
(2) GB/T 14342-2015: Updated national standard for specific resistance measurement of man-made staple fibers.
(3) ISO 2060: Determination of the fineness of fibers by electrical resistivity (analogous methodology).
(4) ASTM D4496: Standard test method for electrical resistance of textile fibers.
(5) EN 1149-1: Protective clothing—Electrostatic properties—Test method for surface resistivity of fibers and textiles.
(6) JIS L 1020: Test method for electrical resistance of textile fibers.
