Cationic Violet 7

Cationic Violet 7, also known as Basic Violet 7, is a synthetic cationic dye specifically developed for dyeing acrylic fibers and their blends. It belongs to the cationic dye class characterized by strong ionic attraction to anionic sites within acrylic polymer structures.

Compared with conventional violet cationic dyes, Basic Violet 7 delivers a  brilliant and clean violet shade with high color strength, making it suitable for both deep and medium shade dyeing requirements. Its balanced molecular structure allows for stable dye uptake, controlled migration, and uniform shade development during the dyeing process.

Basic Violet 7 is Blu-ray colourful red powder. In 20 ℃ water solubility of 10 g/L, solubility effected by temperature is very small, soluble in water for red light purple, in under a yellow of tungsten. In 120 ℃ high temperature dyeing, colored light unchanged. The dye solution should not be boiling. Compatibility value of three, the f value is 0.26.

Product Features

• High Affinity to Acrylic Fibers: Cationic Violet 7 exhibits excellent attraction to acrylic substrates,enabling efficient exhaustion and strong fixation even under standard dyeing conditions.
• Brilliant Violet Hue: Produces a vivid and pure violet tone with good brightness,helping textile manufacturers achieve visually appealing results with minimal shade deviation.
• Uniform Dyeing Performance: Designed to provide good levelness and controlled migration,reducing risks of barre, streaks, or uneven coloration.
• Consistent Batch Reproducibility: Stable chemical properties ensure reliable color matching across multiple dye lots and production batches.
• Process Compatibility: Suitable for standard high-temperature exhaust dyeing processes,with good compatibility alongside other cationic dyes for shade blending.

Applications:

Mainly used to dye the wool, acrylic fiber acrylic scattered and compared acrylic fibers, also can be used in the two vinegar and acrylic fiber direct printing.
