As a dedicated Cationic Brilliant Red 4G supplier, we understand the questions B2B customers frequently ask. Ensuring you buy Cationic Brilliant Red 4G from a reputable source is key to successful dyeing operations. Let’s explore what makes this dye a valuable asset.

What is Cationic Brilliant Red 4G?

Cationic Brilliant Red 4G (CAS 12217-48-0), also known as Basic Red 14, is a synthetic organic dye characterized by its positive charge. This cationic nature makes it highly effective for dyeing substrates that have anionic sites, such as acrylic fibers, wool, and certain modified polyesters. Its typical appearance is a dark red uniform powder, which, when dissolved in water, yields a vibrant, bright red color.

  • Key Properties: High purity (often >99%), excellent solubility, good light fastness (grade 6), and stability at high temperatures (120°C) and across a pH range of 2-6.
  • Molecular Formula: C23H26ClN3
  • Molecular Weight: Approximately 379.93 g/mol

Applications in the Industry

The primary application for Cationic Brilliant Red 4G is in the coloration of acrylic textiles. Its strong affinity ensures deep shades and good fastness properties on:

  • Acrylic loose fibers, fiber strips, and yarns.
  • Diacetate fibers.
  • Modified polyester fabrics, including direct printing.
  • Nylon and blended fabrics, with careful consideration for compatibility.

For those specifically seeking Basic Red 14 for acrylic dyeing, this dye is an excellent choice due to its strong ionic bonding capabilities with acrylic polymers. It is also valuable for direct printing applications where sharp color definition is needed.
