FAQ

Cationic dyestuff, also known as basic dye, is a type of dye that carries a positive charge. It is primarily used for dyeing acrylic fibers, modified polyester, and some synthetic fibers. These dyes offer brilliant shades and excellent brightness, especially suitable for textiles that require high color intensity.

Disperse cationic dyestuff is a hybrid dye that combines the properties of disperse dyes and cationic dyes. Unlike traditional cationic dyes, which are water-soluble and used mainly for acrylics, disperse cationic dyes are designed to dye modified polyester or cationic-dyeable polyester (CDP). They offer better dispersion in water and improved dyeing uniformity on synthetic fibers.

Cationic dyestuffs are ideal for dyeing acrylic fibers, cationic dyeable polyester (CDP), and blends that include these fibers. They have a strong affinity for fibers with anionic (negatively charged) dye sites, allowing for deep dye penetration and vibrant coloration.

Yes, in dyeing blended fabrics (e.g., acrylic/CDP blends), both cationic dyestuff and disperse cationic dyestuff can be used together in a two-bath or even one-bath dyeing process. However, care must be taken to control pH, temperature, and dyeing time to achieve uniform color and prevent cross-staining between fibers.

Cationic dyestuff is mainly used for dyeing acrylic fibers, cationic dyeable polyester (CDP), and some modified synthetic fibers. It provides vivid, bright colors with excellent lightfastness, making it ideal for textiles like sweaters, carpets, and upholstery fabrics.

Disperse cationic dyestuff is specifically designed for dyeing cationic-modified polyester (CDP), whereas traditional disperse dyes are used for standard polyester. The cationic component enhances dye uptake and shade brightness on CDP fibers, resulting in better color yield and uniformity.
