This study analyzed the wrinkling generated in cotton fabrics after household washing and drying processes. An Automated Smoothness Analysis System (ASAS) was developed to increase the reliability of wrinkle quantification. Software developed in MATLAB processed the captured images into the equipment using Canny edge detection. Image processing proved effective, pointing out the need for a large number of visual examiners to achieve an average smoothness level similar to the calculated level by software. A design of experiments 24 allowed the evaluation of the influence of different washing parameters on the wrinkling of fabrics after drying on a clothesline and in a condensation dryer. The relationship between moisture removal and smoothness level was also evaluated. The results showed that the washing load was the common factor that proved to be statistically significant for the wrinkling of the fabric after drying in a domestic dryer. Meanwhile, the number of rinses, type of centrifugation and washing load were influential parameters regarding the wrinkling of fabrics put to dry on a clothesline.
Therefore, this work provided an overview of the main parameters and levels that can excessively wrinkle the studied materials after washing and drying at home.
