Polyurethane Reactive Dye is a special type of reactive dye with the following characteristics:
Suitable for polyurethane fibers: Polyurethane Reactive Dye is specifically designed for dyeing polyurethane fibers (PU fibers). Polyurethane fiber has excellent elasticity and wear resistance and is often used to make elastic fabrics, sportswear, etc. This dye reacts chemically with polyurethane fibers to achieve a stable dyeing effect.
High affinity: Polyurethane Reactive Dye has a high affinity for polyurethane fiber surfaces. It forms covalent bonds with fiber molecules, ensuring that the dye is firmly attached to the fiber. This gives the dyed polyurethane fibers excellent color fastness and washability.
Friction resistance: Due to its strong bond with polyurethane fiber, the dyed fiber has good friction resistance. This means that dyed polyurethane fibers can withstand the friction of daily wear and use and are less likely to fade or fade.
Bright and vivid colors: It has high color intensity and saturation, giving the dyed polyurethane fibers a bright and attractive appearance.
Environmentally friendly: Polyurethane Reactive Dye uses relatively few media and auxiliaries during the dyeing process, reducing negative impact on the environment. In addition, since the dye is firmly bound to the fiber, the dyed textiles will not release harmful substances and comply with environmental protection requirements.
