Knitting fabrics are characterized by the confort they confer on the wearer. Textiles with mcirocpsules are bocoming more popular and nowadays Phase Change Materials (PCM) are used for thermal control and to avoid temperature changes to be clearly noticeable. Consequently, they can control variations in temerpature and make the user feel more confortable. Washing durability and rigidity are very important when considering fabrics treated with microencapsules. In this study we first aimed to study what influence has the resin concentration with the durability of microencapsules on the fabric after having washed it and its confort. To observe the presence of microcapsules after washing procedure the scanning electron microscopy (SEM) was used. SEM analysis showed different density of microcapsules with PCMs depending on the binder concentration used. It could be clearly noticieable that 5times washed fabric and 10times washed fabric still show microacapsules on it. On the other hand we used padding method for the application of PCMs into the fabris and this study put forth the binder effect on rigidity. We have demonstrated that when we increase the binder concentration for padding bath, after 10th laundry cycles for the same fabric, we still have microcalsules on it. On the other hand, density of binder effect negatively influences on rigidity of the fabric.
