Fiber Crimp Elasticity Testing Machine
Category：Fabric & Textile Tester
Introduction
The Fiber Crimp Elasticity Testing Machine is a specialized instrument designed to measure the crimp degree, crimp elasticity, and crimp recovery rate of fibers with linear densities from 1 to 22 dtex. It is widely used in fiber research, production, and quality inspection departments to evaluate both natural and chemical fibers, providing accurate and repeatable measurements for fiber performance analysis and process optimization.
Application
(1) Testing crimp degree and crimp recovery rate of synthetic fibers such as polyester, nylon, acrylic, and rayon.
(2) Evaluating natural fibers including cotton, wool, and blended fibers for crimp elasticity.
(3) Fiber research and development in textile laboratories and nonwoven material production.
(4) Quality control in fiber spinning, carding, and finishing processes.
(5) Comparative studies of crimp performance for recycled or blended fibers.
(6) Assessment of fibers used in technical textiles for automotive, medical, and smart textile applications.
(7) Education and training purposes in fiber science and textile engineering programs.
Standards
(1) GB/T 14338-2008: Test method for crimp and crimp elasticity of staple fibers.
(2) GB/T 14338-2022: Updated national standard for crimp performance of man-made staple fibers.
(3) ISO 2060: Determination of fiber fineness by electrical or physical methods (applied analogously).
(4) ASTM D885: Standard test methods for crimp characteristics of textile fibers.
(5) EN 1269-1: Test methods for staple fibers—crimp characterization and recovery rate measurement.
(6) JIS L 1013: Methods for evaluating crimp and elasticity of textile fibers.
