👉 Redrying is a process in which fibers are dried at high temperatures, typically around 140-150°C, to achieve a uniform and dense texture. This process is commonly used in the production of yarns and fabrics for various applications such as knitting, weaving, and upholstery. It involves heating the fiber to a specific temperature, causing it to undergo a chemical change that results in the formation of a solid material known as a dyed filament.
