What does cold dye fix mean?

Cold dye fix refers to a method of dyeing fabrics where the dye is applied at low temperatures, typically without the need for heat to set the color. This process often uses specific types of dyes that bond well with the fibers at room temperature, allowing for vibrant colors without the risk of damaging the fabric. Cold dye fix techniques are popular for delicate materials and for achieving certain color effects, making them valuable in textile processing.
