For professionals in the textile and chemical industries, a thorough understanding of chemical properties is key to successful product development and manufacturing. Basic Red 46 (CAS: 12221-69-1) is a prime example of a specialty chemical that demands precise knowledge for optimal use. As a dedicated supplier of high-quality dyes, we aim to provide essential insights into this crucial cationic dye.

Chemical Identity and Properties of Basic Red 46

Basic Red 46 is a synthetic azo dye, known chemically as C.I. Basic Red 46. Its molecular formula is C18H21BrN6, with a molecular weight of approximately 401.30 g/mol. It presents as a dark red powder. The dye's classification as a cationic dye means it carries a positive charge, enabling it to form strong electrostatic bonds with anionic sites on substrates. This inherent property makes it exceptionally effective for dyeing acrylic fibers, which typically possess a negative charge due to the presence of sulfonate or carboxyl groups.

The dye exhibits good solubility in water, which is advantageous for standard aqueous dyeing processes. Furthermore, it is noted for its excellent levelness and fastness properties when applied correctly. This translates to uniform coloration across the fabric and resistance to fading from common treatments like washing and exposure to light.

Applications Across the Textile Spectrum

The primary utility of Basic Red 46 lies in its application for dyeing acrylic fibers and blends. It is extensively used in the textile industry for coloring:

  • Acrylic loose fibers
  • Acrylic fiber strips
  • Acrylic fleece
  • Acrylic blankets and knitted fabrics

Beyond solid dyeing, Basic Red 46 is also suitable for direct printing applications, allowing for intricate designs and patterns on textiles. Its compatibility with other cationic dyes, such as specific yellow and blue variants, allows for the creation of a wide range of secondary and tertiary colors, making it a versatile tool for color formulation and matching.
