The textile and fiber industries rely on high-performance dyes to achieve vibrant, durable, and consistent coloration. NINGBO INNO PHARMCHEM CO.,LTD. offers Solvent Green 3 (CAS 128-80-3), an advanced anthraquinone solvent dye that provides significant advantages for coloring various synthetic fibers, particularly PET (Polyethylene Terephthalate) fibers.

Solvent Green 3 is an oil-soluble dye that imparts a brilliant bluish-green hue with excellent clarity. Its application in PET fiber coloration is highly effective due to its solubility characteristics and thermal stability. During the melt spinning process for PET fibers, the polymer is heated to high temperatures. Solvent Green 3’s impressive heat resistance, up to 300°C, ensures that the dye remains stable and does not degrade or change color, allowing for the production of brightly colored fibers that are consistent in shade and quality.

The light fastness of Solvent Green 3 is rated at 7-8, which is crucial for textile applications. This high level of light fastness means that fabrics and fibers colored with this dye will resist fading when exposed to sunlight or other light sources over time. This durability is essential for apparel, upholstery, and other textile products that are expected to maintain their aesthetic appeal throughout their lifespan.

Beyond PET fibers, Solvent Green 3 finds utility in other synthetic fiber dyeing processes where solvent dyeing is employed. Its strong dyeing power allows for deep, saturated colors to be achieved with relatively low concentrations, contributing to efficient and economical dyeing operations. The dye's ability to disperse uniformly within the fiber matrix also prevents issues like uneven dyeing or streaking, ensuring a premium finish.

NINGBO INNO PHARMCHEM CO.,LTD. is dedicated to providing high-quality chemical products that meet the rigorous demands of the textile industry. Solvent Green 3, with its combination of vibrant color, excellent thermal stability, superior light fastness, and efficient dyeing properties, is a prime example of such a product. Manufacturers looking to produce high-quality, colorfast green textiles and fibers can confidently incorporate Solvent Green 3 into their processes, benefiting from the consistent performance and aesthetic advantages it offers.
