Acid Blue 90, commercially known as Brilliant Blue G250 (CAS 6104-58-1), is a versatile acid dye valued for its brilliant blue hue and broad applicability in various dyeing processes. For professionals in the textile industry, understanding the optimal application conditions for this dye is key to achieving superior results. NINGBO INNO PHARMCHEM CO.,LTD., a prominent manufacturer and supplier of dyes in China, provides essential insights into the effective use of Acid Blue 90.
In the dyeing of wool, Acid Blue 90 is typically applied in a weakly acidic bath. The pH is carefully controlled, usually between 4 and 6, with dyeing commencing at 50-60°C. The temperature is then gradually raised to 85-95°C to ensure complete exhaustion and level dyeing. This process results in a bright and consistent blue shade, which is highly desirable for wool fabrics. When considering purchasing this dye, sourcing from a reputable China manufacturer like NINGBO INNO PHARMCHEM ensures consistent quality and competitive pricing.
Silk dyeing with Acid Blue 90 also utilizes a weakly acidic bath, yielding a bright color. While the inherent fastness properties on silk might be moderate, employing post-dyeing treatments with synthetic tannin fixing agents, followed by cationic fixing agents, can significantly improve the wet fastness and overall durability of the dye. This is particularly relevant for printed silk fabrics where color retention is crucial. Buyers looking to buy Acid Blue 90 for silk applications should inquire about these finishing options.
For nylon dyeing, similar principles apply. A weakly acidic bath is recommended, and treatment with synthetic tannin fixing agents is advised to enhance the wet fastness properties. The dye's compatibility with these treatment processes makes it a reliable choice for nylon textiles. As a leading supplier, NINGBO INNO PHARMCHEM CO.,LTD. offers expert advice on optimal application and fixing methods to maximize the performance of Acid Blue 90 in your specific industrial processes.
Furthermore, Acid Blue 90's properties of dissolving in hot water and ethanol contribute to its ease of use in various industrial dyeing and printing operations. Its dark brown powder form is stable and manageable, making it a practical choice for manufacturers. For businesses seeking a consistent and cost-effective supply of this dye, engaging with a trusted China manufacturer like NINGBO INNO PHARMCHEM is a strategic step towards optimizing your dyeing operations.
