“…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 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,

“…Therefore, a system is needed that can accurately quantify surface smoothness in a practical and repeatable manner. Previous research efforts have focused on this goal with limited success [2,3,4,5,6,7,10,14,15,16]. Of special interest are previous efforts that are similar to this work.…”

In this research, we validate an imaging system for automatic grading of fabric smoothness, developed at Texas Tech University. This system consists of a sheet-of-light, laser-line projector; a smart CMOS camera; a moving platform; and a PC. Its purpose is to provide the textile industry with a tool for rapid, objective evaluation of fabric smoothness after home laundering. The validation study involves two cotton fabrics treated with increasing amounts of a textile-finishing agent to impart durable press properties. The UATR-FTIR is used as a rapid and nondestructive technique to determine the amount of the crosslinking agent linked to the cellulose after the required laundering cycles. To demonstrate the potential of our newly developed imaging system, we extract five features from the acquired images and relate them to AATCC grading and to the amount of finish as evaluated by FTIR. Our results demonstrate that this new wrinkle measurement technology has the potential to discriminate between different levels of fabric treatments and different fabrics.Durable press-referred to as smoothness-is a term used for apparel that requires little or no ironing after home laundering and has wrinkle resistance properties during daily wear. Such garments have become prominent consumer items. The protocol for ascertaining the smoothness grade of a fabric is outlined in the American Association of Textile Chemists and Colorists (AATCC) test method (TM) 124 [1]. This standard test is designed to evaluate the smoothness of fabric specimens after five cycles of home laundering. Once three specimens per fabric have been through five standard washing-drying cycles, three technicians visually evaluate their appearance. For these evaluations, each specimen is laid on a solid surface that stands at an incline of 5 degrees from the vertical under specified lighting conditions. The specimen is then compared to six standard replicas, which are 3D plastic models, showing varying degrees of smoothness and having grades 1 (very wrinkly), 2, 3, 3.5, 4, and 5 (very smooth). The specimen is assigned the grade of the replica it most closely resembles (Figure 1).Cotton is made up of cellulose with repeating anhydroglucose units, and on each unit are three available hydroxyl groups. The basic idea behind the resistance of cotton to wrinkles is to restrict the slippage of cellulose chains [9]. Chain slippage can be restricted by an appropriate chemical treatment, which establishes covalent links between the cellulosic chains in the amorphous regions of the cellulosic fibers. For many years, the textile industry has been using N-methylol based products with very low formaldehyde release as the crosslinking agent. The most common method for finishing the cotton fabric is the pad-dry-cure process, which consists of impregnating the sample in an aqueous solution containing the crosslinking agent and the appropriate catalyst, padding the impregnated fabric to 90 -100% wet pick-up, drying, and then curing.Infrared spectroscopy has been used to confirm ...
