The invention relates to a transmission type measurement device, method and application of fiber bundle arrangement uniformity and fracture form. The device includes a wide-angle lens, a CCD camera, an LED light source board, a camera platform that can move up and down, a translation mechanism that can move horizontally, an anti-vibration base, a bundle fiber stretching mechanism, and computer control and data analysis coefficients. The device provided by the invention is simple in structure, high in measurement accuracy, and real-time dynamic; the measurement method is an analysis method with multiple indicators on one side and multiple passwords on deformation and properties, and is suitable for the bundle strength measurement of textile fibers, fiber bundle arrangement uniformity, tension Consistency of tensile fracture end shape and evaluation of weak joint characteristics. The outline of the fracture end and the light transmittance are compared with each other and with the force value and displacement value.
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...
