Polyester, a widely used synthetic fiber, is celebrated for its durability and versatility. However, like many raw materials, it often possesses a slight yellowish tint that can diminish the perceived quality of finished textiles. To counteract this, manufacturers rely on sophisticated whitening solutions, among which Optical Brightener ERN C.I.135 stands out as a highly effective agent.

Optical brightening agents (OBAs), or fluorescent brighteners, function by absorbing invisible ultraviolet (UV) light and re-emitting it as visible blue light. This blue light counteracts the inherent yellowness of the fabric, making it appear whiter and brighter to the human eye. This optical effect creates a perception of enhanced cleanliness and vibrancy, crucial for consumer appeal.

Optical Brightener ERN C.I.135, specifically, is a Stilbene derivative fluorescent brightening agent designed for superior polyester textile whitening. Its core properties include delivering exceptional high whiteness and a remarkable strong fluorescent light effect. Furthermore, it offers a low cost and is notably convenient to use, making it an attractive option for industrial applications.

The application versatility of this brightener is a significant advantage. It can be effectively integrated into both the pad-thermosol dyeing process optical brightener, where it cures at high temperatures (180-200°C) for optimal fixation, and the HT exhausting process brightener polyester, typically at 120-130°C. Careful adjustment of pH (to 4-5 with acetic acid for pad-thermosol) is essential to ensure maximum efficacy and brilliant results, preventing issues like uneven whitening.
