Fabric pleating refers to the process of pressing and folding fabric through heating, moistening, and pressure to create a certain amount of wrinkles and pleating effects. This technique can add dimension and texture to fabrics, injecting more design elements into the field of clothing. The basic steps of fabric pleating include sampling, pre-treatment, dyeing and finishing, post-treatment, and pleating. Among them, post-treatment is one of the most important steps in pleating, where the fabric needs to be finished before being pleated to achieve the best results.
