摘要

织物的压缩性能在大多数最终用途中都很重要。传统的压缩测试仪，如KESF (Kawabata Evaluation System for Fabrics)和FAST (Fabric Assurance by Simple Testing)系统，用于执行离线静态测量。正在开发的在线测量压缩性能的原理是基于织物在通过一对滚轮形成的夹缝时的变形分析，其中一个滚轮由电机控制并连接在称重传感器上。被测试样在测量系统中连续移动，同时在夹紧区以恒定速率进行压缩变形。得到了织物的载荷-位移随时间的关系。假设织物在厚度方向上呈阶梯各向异性，得到了织物在压缩过程中的应力-应变关系。

Online measurement of fabric mechanical properties: compressional behavior

Compressional behavior of fabrics is important in most end uses. The traditional compression testers such as KESF (Kawabata Evaluation System for Fabrics) and FAST (Fabric Assurance by Simple Testing) systems are used to perform offline static measurements. The principle of online measurement of compressional behavior being developed is based on the analysis of fabric deformation while the fabric moves through a nip formed by a pair of rollers, one of which is controlled by a motor and is attached to a load cell. The specimen being tested is moved continuously through the measurement system, while it is deformed in compression at a constant rate in the nip area. The load-displacement relation of the fabric is then obtained as a function of time. Assuming a stepwise anisotropic behavior in the thickness direction, the fabric stress-strain relation in compression is obtained.
