For procurement managers in the textile industry, sourcing reliable and high-quality dyestuffs is paramount. Fast Blue-FFRL, identified by CAS number 74749-42-1, stands out as a valuable blue intermediate. Understanding its characteristics and applications can significantly streamline your purchasing process and ensure the quality of your final products. This article serves as a guide to help you navigate the procurement of Fast Blue-FFRL.

Fast Blue-FFRL is a fine blue powder, characterized by its molecular formula C14H12Cl2N4O2 and a molecular weight of 339.18. Its primary utility lies in the vibrant blue shades it imparts to various fabrics. As a key dyestuff intermediate, it is crucial for manufacturers aiming for specific color outcomes.

The most common application for Fast Blue-FFRL is in the dyeing of cotton and viscose fabrics. It is lauded for its ability to achieve bright blue colors through medium migration dyeing techniques, ensuring good leveling. This means that when properly applied, the dye disperses evenly across the fabric, preventing patchiness and achieving a uniform, appealing finish. This characteristic is highly sought after by textile mills focusing on quality and consistency.

Beyond cotton and viscose, Fast Blue-FFRL also finds application in the dyeing of silk and its blended fabrics. Its versatility allows for the coloration of a range of natural and synthetic fibers, broadening its appeal to diverse textile manufacturers. For polyester/viscose blends, it can be employed in conjunction with disperse dyes, yielding a subtly reddish blue hue when processed at the same bath temperature. This nuanced color variation offers creative possibilities for designers and manufacturers.

An essential property that makes Fast Blue-FFRL a preferred choice is its good fastness to light. This means that fabrics dyed with this intermediate are less prone to fading when exposed to sunlight, ensuring the longevity of the color and the aesthetic appeal of the finished textile products. For brands and manufacturers focused on durability, this attribute is a significant advantage.

When considering the purchase of Fast Blue-FFRL, it is important to note the typical properties and recommended storage. The product usually presents as a blue fine powder with an intensity of 100%. Proper storage involves keeping the warehouse ventilated and dry, ideally at low temperatures to maintain product integrity. Standard packaging often includes 25kg drums, suitable for bulk orders.

For businesses looking to buy Fast Blue-FFRL, sourcing from reputable Fast Blue-FFRL manufacturers or Fast Blue-FFRL suppliers is crucial. Companies that can provide consistent quality, competitive Fast Blue-FFRL prices, and reliable delivery are essential partners. When inquiring, be sure to request product specifications and any available safety data sheets (SDS) to ensure compliance and safe handling. Exploring options from Chinese manufacturers can often provide cost-effective solutions without compromising on quality, especially when you partner with established chemical suppliers.

In summary, Fast Blue-FFRL is a valuable dyestuff intermediate for the textile industry. Its bright blue color, excellent dyeing properties, and good lightfastness make it a popular choice for coloring cotton, viscose, silk, and blended fabrics. Understanding these attributes and knowing how to source effectively from qualified suppliers will empower procurement managers to make informed decisions, securing the quality and value their businesses demand.
