[0030] Please refer to figure 1 , the present embodiment provides a fiber orientation testing device 100, which includes a compression device 110 and an electrode system 120, the electrode system 120 is disposed inside the compression device 110, and is used for testing compressed loose fibers.

[0031] The bulk fiber is compressed by accommodating the bulk fiber in the compressing device 110 , and at the same time, the electrode system 120 detects the horizontal and vertical resistance of the bulk fiber during the compression process. The method realizes the indirect test of the arrangement of the fibers in the aggregate after the fibers in the aggregate of loose fibers are compressed. The fiber orientation degree f given by the device can accurately and comprehensively reflect the arrangement of fibers along the compression direction and vertical compression direction.

[0032] Further, the compression device 110 includes a frame body 111 and a movable part, the movable par...

Abstract

The invention relates to the field of fibers, in particular to a fiber directionality testing device. The fiber directionality testing device comprises a compression device and an electrode system, wherein the compression device is used for compressing dispersive fibers; the electrode system comprises a first electrode, a second electrode and a resistance tester; the first electrode is arranged in the compression device in the horizontal direction, and can generate displacement in the fiber compression direction; the second electrode is arranged in the compression device in the direction vertical to the first electrode; the resistance tester is electrically connected with the first electrode and the second electrode, and is used for testing the resistance value of the compressed dispersive fiber in the horizontal / vertical direction. The fiber directionality tested by the method can accurately and comprehensively reflect the arrangement condition of fibers in the compression direction and vertical compression direction.

Description

technical field [0001] The invention relates to the field of fibers, in particular to a fiber orientation testing device. Background technique [0002] Generally, the distribution state of fibers in loose fiber aggregates is random and disorderly, and the arrangement has no specific direction. In the process of researching loose fiber aggregates, the existing technical solutions and testing devices basically focus on the testing of bulk fiber compression properties such as: GB / T24442.1-2009, Textiles, Part 1 of Determination of Compression Properties: Constant Method And GB / T24442.2-2009, Textiles, Determination of Compression Properties Part 2: Isokinetic method. There is no report on the test method and device of the alignment state of the fibers in the compression process in the prior art solutions. After the fiber aggregate is compressed, it is difficult to directly observe the arrangement of fibers in the aggregate to reflect the arrangement of fibers in different dir...
