Problems solved by technology

[0002] In recent years, the measurement of fiber friction performance has become increasingly important, mainly because it is used to judge processing performance, and is mostly used in new chemical fiber varieties and new oil formulations. However, fiber friction testing is an ultra-fine operation, and different testing methods can be obtained The data differ greatly and are not comparable. The commonly used instrument for testing fibers is mainly the Y151 fiber friction coefficient detector, which can detect the dynamic and static friction coefficients between various textile fibers, and can also measure textile fibers and metals. The static and dynamic friction coefficient between rubbers, but it is not reported for elastic fibers such as spandex fiber friction coefficient. At the same time, the reference fiber friction performance test method, Tianjin Textile Science and Technology No. 190 P11-14 discloses some typical tests The method of fiber friction properties, which is a laboratory-level test method and is not suitable for "on-line" measurement

Abstract

The invention provides a device for continuously measuring a friction coefficient between elastic fibers. The device comprises a tension sensor (1), a first yarn guide wheel (1-1), a second yarn guide wheel (2), a third yarn guide wheel (3), a processor (4), a suspension weight (5), a fourth yarn guide wheel (6), a panel (7), a fixing support (8), a winding roller (9) and a steering yarn guide wheel (10). The elastic fibers are wound between the third yarn guide wheel (3) and the fourth yarn guide wheel (6) for one circle or several circles so that twisted points can be formed, and then the dynamic friction coefficient between the elastic fibers is measured by detecting friction force of the fibers on the twisted points. The device smoothly solves the difficult technical problems that the elastic fibers are prone to deforming and tension detection differences are large, high precision and continuous detection of the elastic fibers are achieved, and measurement results have the characteristics that all the measurement results are expressed with numbers and precision is high.

Description

technical field [0001] The invention relates to a device for continuously measuring the friction coefficient between fibers, especially a device for measuring the friction coefficient between elastic fibers. Background technique [0002] In recent years, the measurement of fiber friction performance has become increasingly important, mainly because it is used to judge processing performance, and is mostly used in new chemical fiber varieties and new oil formulations. However, fiber friction testing is an ultra-fine operation, and different testing methods can be obtained The data are very different and not comparable. The most commonly used instrument for testing fibers is the Y151 fiber friction coefficient detector, which can detect the dynamic and static friction coefficients between various textile fibers, and can also measure textile fibers and metals. The static and dynamic friction coefficient between rubbers, but it has no report on the elastic fiber, such as the spa...
