For procurement specialists and R&D professionals in the textile industry, a thorough understanding of chemical specifications is crucial for successful product development and manufacturing. Disperse Black ECT 300% is a widely utilized dye for polyester fibers, and knowing its technical parameters ensures optimal application and desired results. As a leading manufacturer and supplier of high-quality textile chemicals, we provide detailed insights into the specifications of this vital product.

The core of Disperse Black ECT 300%'s performance lies in its standardized specifications. A key parameter is the '% OWF' (on weight of fiber), which indicates the dye's concentration or strength. A 300% OWF rating signifies a highly concentrated product, meaning less dye is required to achieve a deep, rich black shade on polyester fabrics. This concentration translates to cost efficiency and improved process management for manufacturers looking to buy in bulk.

Fastness properties are another critical consideration. Disperse Black ECT 300% typically exhibits strong performance in several key areas: Light Fastness (rated on a scale, higher is better), Washing Fastness (resistance to color loss during washing), and Sublimation Fastness (resistance to color bleeding or transfer under heat, crucial for processes like heat setting or ironing). Our product generally scores well in these categories, often achieving ratings of 5-6 for light fastness, 4-5 for washing fastness, and 3-4 for sublimation, ensuring durable and appealing color on finished textiles. Understanding these ratings helps buyers make informed decisions when comparing suppliers.

The pH range is also important for dyeing processes, as it affects dye solubility and affinity to the fiber. Disperse Black ECT 300% is typically stable and effective within a pH range of 3-9. This broad range offers flexibility in formulating dye baths, accommodating different water qualities and auxiliary chemicals. When you purchase from us, you benefit from a product that is engineered for broad applicability, simplifying your formulation process and ensuring consistent dyeing outcomes.
