Abstract

The invention relates to a transmission type measuring device and method of arrangement uniformity and fracture morphology of a fiber bundle, and a purpose. The device comprises a wide-angle lens, a CCD camera, an LED light source plate, a shooting table capable of moving up and down and back and forth, a translation mechanism capable of moving left and right, an anti-vibration pedestal, a bundlefiber stretching mechanism, and a computer control and data analysis system. According to the device, the structure is concise, the measuring precision is high, and dynamic real-time measurement is realized; and the measuring method is a single-side multi-index, deformation and property multi-command analysis method and is applicable to arrangement uniformity, and morphology consistence and weak-link characteristic assessment of stretching fracture ends of fiber bundles in bundle intensity measurement of textile fibers; and contour lines and the transmittance of the fracture ends are mutuallycompared and are compared with force values and displacement values.

Description

technical field [0001] The invention relates to a transmission type measurement device, method and application of fiber bundle arrangement uniformity and fracture form, which are applicable to various textile fibers such as wool, hemp and cotton, and belong to the technical field of optical measurement methods. Background technique [0002] Cotton, wool, hemp and other textile fibers are mainly used in the textile industry. The content of fiber bundles and the length distribution after fiber breakage are one of the important indicators for detecting fibers. Therefore, the length distribution after fiber breakage is detected after tensile fracture. One of the important items. [0003] At present, the detection methods used in the world are mainly the following categories: 1. Traditional method: also known as the ruler measurement method, which is to place the broken fiber sample on a black velvet board and measure the fiber density of the whole fiber one by one with a stainle...
