Tetraacetylethylenediamine (TAED) has been explored as an activator for hydrogen peroxide (H2O2) in the bleaching of scoured jute fibers, offering a promising alternative to traditional bleaching methods.
In comparison to conventional H2O2 bleaching, the TAED-activated H2O2 system demonstrated superior storage stability of whiteness and yellowness. Additionally, jute fibers treated with TAED-activated H2O2 exhibited higher breaking tenacity, lower fineness value, and increased resistance to extension. Morphological and thermogravimetric analyses revealed that this method more effectively removed noncellulosic materials, notably lignin, compared to the conventional H2O2 bleaching process. The TAED-activated system also achieved similar hemicellulose removal but required significantly lower H2O2 concentration, bleaching temperature, and time for comparable whiteness and yellowness outcomes. The use of a buffer solution to adjust pH to 8.0 further optimized the bleaching process. This study indicates that TAED-activated H2O2 offers an enhanced, environmentally friendlier method for bleaching jute fibers with improved physicochemical properties, providing potential benefits for industrial textile processing.

Tetraacetylethylenediamine (TAED) has been successfully utilized in the development of color-tunable ultralong room temperature phosphorescence (RTP) materials, offering a novel approach for full-color afterglow with applications in displays, sensors, and optoelectronic devices.
By incorporating TAED into a polyurethane (PU) polymer host, a green afterglow was achieved. This system was further modulated using three typical disperse dyes as guests, enabling full-spectrum afterglow through the phosphorescence resonance energy transfer (PRET) process. The interaction between TAED and the disperse dyes facilitated predictable afterglow colors across the visible spectrum, with a prediction accuracy of 88.89%. This performance exceeds that of conventional dye systems and offers a simpler, more predictable method for tuning RTP emission. The strategy provides a significant advancement in the design of full-color RTP materials, linking theoretical color science to practical customization in polymeric systems. This work opens up possibilities for creating efficient and customizable luminescent materials for a wide range of applications, including information encryption, optoelectronic devices, and advanced sensor technologies.

Tetraacetylethylenediamine (TAED) has been effectively employed in an ultrasound-assisted strategy for one-bath, one-step scouring and bleaching of cotton/spandex fabrics, in combination with sodium percarbonate (SPC).
In this process, SPC serves as both a pH regulator and H2O2 donor, facilitating the release of peracetic acid (PAA) from TAED. A central composite design was used to investigate the effects of operational parameters such as TAED concentration, temperature, and time on the Whiteness Index (WI) of the fabric. Results indicated that temperature had the most significant impact on WI, followed by TAED concentration and time. The increase in temperature led to a decrease in PAA concentration and an increase in hydroxyl radical (HO·) concentration, both crucial for enhancing the bleaching effect. Notably, the ultrasound-assisted process enabled a 43% improvement in WI compared to untreated fabric, achieving a WI of 68.6 at a reduced temperature (40 °C) for just 40 minutes, demonstrating energy savings over conventional methods. The treated fabric exhibited minimal tensile strength loss (<5%), maintaining its mechanical integrity, and improved wettability, resulting in better dyeing performance. This study highlights the potential of TAED in ultrasound-assisted textile bleaching, offering a sustainable and efficient solution for fabric pre-treatment in the textile industry.
