At NINGBO INNO PHARMCHEM CO.,LTD., we are committed to providing the chemical building blocks that drive innovation in various industries. For the textile sector, achieving vibrant and lasting colors on synthetic fibers like polyester is a key objective. This is where our high-quality Disperse Blue 359 comes into play, offering superior performance characteristics essential for modern polyester dyeing and printing processes.

Disperse Blue 359, with CAS Number 62570-50-7, is a finely engineered anthraquinone dye. Its chemical formula, C17H13N3O2, and molecular weight of approximately 291.3 g/mol, contribute to its excellent affinity for polyester fibers. The dye is presented as a fine blue powder, which is characteristic of disperse dyes designed for optimal dispersion and application in aqueous dyeing baths or printing inks.

The key specifications of our Disperse Blue 359 include a high purity content (typically ≥90%), low moisture levels (≤1%), and a controlled pH range (6-8). These parameters are crucial for consistent dyeing results. The dye exhibits a remarkable light fastness rating (typically 7) and good washing fastness (4-5), ensuring that fabrics retain their rich blue hue even after repeated washing and exposure to light. Its sublimation properties are also noteworthy, making it ideal for heat transfer printing applications.

The primary application of Disperse Blue 359 is in the dyeing and printing of polyester and its blended fabrics. The non-ionic nature of disperse dyes allows them to penetrate the hydrophobic polyester fibers effectively, forming strong bonds that result in vibrant and durable coloration. This contrasts with other dye classes that may not be suitable for synthetic materials.

NINGBO INNO PHARMCHEM CO.,LTD. sources and supplies Disperse Blue 359 with a focus on quality assurance. We understand the importance of reliable raw materials for textile manufacturers. Our product is designed to meet industry standards, offering a cost-effective solution that balances performance with environmental considerations, by enabling more efficient dyeing processes.
