Description

Technical Field

[0001] This invention relates to the field of optical testing technology, and more specifically to an aurora testing system and method for uniform fabrics. Background Technology

[0002] Aurora phenomena refer to the abnormal enhancement of surface gloss or the appearance of mottled light spots on fabrics under frequent friction, pressure, or stretching, severely affecting the appearance of clothing. This problem is particularly prominent in wool and blended uniform fabrics. Early industry reliance on visual inspection to determine the degree of aurora was a subjective method lacking quantitative standards, leading to significant quality fluctuations between different batches of fabric. Currently, the detection of aurora phenomena in uniform fabrics mainly relies on traditional gloss meters, which have significant limitations. Visual inspection is highly subjective, greatly influenced by ambient light and human experience, and cannot provide quantitative data; while ordinary gloss meters can measure surface reflectivity, they struggle to distinguish between aurora and normal highlight areas, resulting in a high rate of misjudgment.

[0003] In recent years, machine vision and artificial intelligence technologies have been gradually applied in the field of textile inspection, providing new solutions for aurora testing. Through multi-angle light source imaging and image analysis algorithms, the reflective characteristics of the fabric surface can be accurately captured. Combined with AI models, aurora and ordinary gloss can be distinguished, achieving automated detection. However, existing technologies lack intelligent measurement of fiber orientation, relying solely on surface reflective characteristics for judgment. They lack quantitative measurement of the microscopic arrangement direction of fibers and do not combine fiber orientation with changes in gloss for comprehensive analysis, resulting in the accuracy and reliability of aurora detection still needing improvement. Furthermore, the lack of quantitative comparison of aurora gloss makes it impossible to accurately assess the impact of aurora on the gloss of uniform fabrics. Summary of the Invention

[0004] In order to overcome the above-mentioned defects of the prior art, the present invention provides an aurora testing system for uniform fabrics to solve the problems existing in the background art.

The three-dimensional fiber orientation analysis module uses a high-precision three-dimensional scanner to perform non-contact measurement of the fiber orientation on the surface of the sampled fabric, obtains the three-dimensional arrangement information of the fibers, distinguishes the warp and weft directions of the sampled fabric and labels them respectively. The initial gloss measurement module calibrates the gloss measuring instrument and reads the initial gloss value of the sampled fabric through the gloss measuring instrument after calibration. The initial gloss value includes the initial warp gloss and the initial weft gloss. The aurora test gloss comparison module rubs the abrasive surface of the sampled fabric against the abrasive friction surface on the grinding table of the aurora generator to obtain the gloss of the sampled fabric after the aurora is generated, and compares and analyzes the gloss of the sampled fabric before and after the aurora test. The uniform fabric gloss evaluation module receives the comparative analysis results of the gloss of the sampled fabrics before and after the aurora test, and performs a comprehensive evaluation of the aurora test on the uniform fabrics.

Divide the surface into n local windows and calculate the gradient direction angle for all points in each window; The direction corresponding to the maximum gradient direction angle of each window is the local principal gradient direction. And obtain the fiber orientation angle of each window based on the local principal gradient direction; Analyze the angle deviation between the fiber orientation angle of each window and the preset reference direction. The fiber orientation angle corresponding to the smallest deviation is the warp direction of the fabric, and the warp direction plus or minus 90 degrees is the weft direction of the fabric.

To read the initial gloss value of the sampled fabric: Place the sampled fabric face up, attach it to the sample stage according to the warp markings, place the sample stage in the measurement area, and read the initial warp gloss of the sampled fabric. Then, rotate the sample stage 90° clockwise and read the initial weft gloss of the sampled fabric.

The sampled fabric after the aurora occurred is returned to the initial gloss measurement module for gloss measurement after the aurora occurred. The gloss measurement includes warp gloss and weft gloss. The initial warp and weft gloss of the sampled fabric were compared with the warp and weft gloss of the sampled fabric after the aurora was generated, and the warp and weft gloss change rates of the sampled fabric were calculated.

[0010] Preferably, the specific content of the uniform fabric gloss evaluation module is as follows: The comparative analysis results of the gloss of the sampled fabric before and after receiving the aurora test, wherein the results represent the rate of change of the warp gloss of the sampled fabric and the rate of change of the weft gloss of the sampled fabric; When acquiring multiple sample fabrics, the average of the warp gloss change rate of the multiple sample fabrics is taken as the warp gloss change rate of the final sample fabric, and the average of the weft gloss change rate of the multiple sample fabrics is taken as the weft gloss change rate of the final sample fabric.
