Analysis of Wrinkle Properties of Fabrics Using Wavelet Transform

In this paper, the application of image analysis to assess the fabric wrinkle and abrasion resistance in order to compare with experimental methods is described. Three samples of cotton fabrics (plain) with different finishing treatments were tested. In the present work, employing an appropriate lighting method, sample images were captured by scanner, and then images prepared from samples were processed in MATLAB. Finally, the number which evaluates each mentioned property was achieved. The results compare wrinkle and abrasion with experimental evaluation, revealing that data from image analysis is more precise than experimental data.

“…The last characteristic is the wrinkle sharpness. We evaluated several descriptors suitable for wrinkle evaluation, including luminance statistical functions, Haralick textural features, 3 frequency and amplitude analysis based on 2D-fast Fourier transform (FFT) 2,5 fractal dimension calculation, 7,15 wavelet analysis, 6 and edge detection-based descriptors. 4 We selected two quantitative descriptors to evaluate wrinkles that are closely related to the wrinkle properties as perceived by the evaluators: the standard deviation of luminance, and the summation of wrinkle edge strength.…”

The 3D information from fabric is usually extracted by laser line projection 6–12 or different stereo techniques. 13–15 These systems are usually tested using wrinkle replicas or fabric samples of simple geometry, instead of actual clothes.…”

The appliance industry requires a reliable method for wrinkle evaluation in textile materials. This method is necessary to assess the performance of new designs of tumble dryers. In this paper, we describe an objective evaluation system for wrinkle appearance grading based on the digital analysis of luminance images. The system is capable of evaluating wrinkles in real garments using the legacy inspection booth designed for subjective evaluation. Therefore, the results from the objective evaluation of wrinkles can be compared to the historical records. The dependence of luminance on the threedimensional characteristics of the wrinkles is modeled and discussed. Based on this analysis, we propose a method supported by two descriptors closely related with the wrinkle characteristics as appreciated by trained evaluators. The design incorporates filtering algorithms that eliminate the influence of undulations and the non-uniform illumination. The objective wrinkle evaluation showed high correlation with human experts and robust performance, as demonstrated by the repeatability and reproducibility study.Every engineering effort oriented to the optimization of a process involves the acquisition of objective, quantitative, and accurate information about performance in order to assess the improvement. In recent years, innovative functions have been incorporated to laundry dryers in order to eliminate wrinkles or minimize their generation in clothes. The efficacy of new designs is usually evaluated by a subjective test where the wrinkle degree of a batch of shirts is evaluated before and after being smoothed by a prototype dryer. This information is used as feedback for the process of dryer design optimization. The subjective test is based on the Method 124, ''Appearance of fabrics after repeated home laundering'', published by the American Association of Textile Chemists and Colorists (AATCC). 1 This method was designed to evaluate the smoothness appearance (SA) of flat fabric specimens. The SA is defined as the visual impression of planarity of a specimen, quantified by comparison with a set of reference standards. These reference standards are six fabric wrinkle replicas commercialized by the AATCC. The replicas, shown in Figure 1, are three-dimensional (3D) reproductions of fabric wrinkles with nominal SA grades from 1 to 5. According to this method, three trained observers should rate each specimen using the inspection booth shown in Figure 2. The overhead fluorescent lamps should be the only light source for the viewing board. All other lights in the room should be turned off. The observer stands directly in front of the specimen, 120 cm away from the board. The test specimen is mounted on the viewing board,

This article investigates the effects of selected finishing methods on wrinkle resistance of laminated and non-laminated car seat cover fabrics. This study was carried out on five types of fabrics that have different properties. Apart from the reference fabric that is commonly manufactured in the automobile industry, four fabrics were produced using four different methods. All sample fabrics were knitted with a three-bar tricot machine at a conventional mill under the same conditions. As seat cover fabrics are generally laminated, sample fabrics were tested as laminated and non-laminated in order to investigate the effect of lamination. Samples were laminated with polyurethane and another warp knitted fabric that was knitted with a two-bar tricot machine and served as a lining. During the study, the wrinkle resistances of 10 laminated and non-laminated fabrics were measured at regular intervals. When the findings of the study were analyzed graphically and statistically, the method of using softening agent at foulard was found to be the most convenient one to produce high wrinkle resistant seat cover fabrics.
