“…It may be noted that sustainability in UV curing applications has been predominantly centered on deriving components from renewable resources. 1,3,4,7,8 This development introduces sustainability in the process itself thus enhancing its usefulness. In addition, the acid-base approach demonstrated for UV curing processes has the potential for conventional emulsion polymerization also, particularly for surfactant free emulsion polymerization 53 and coalescing agent free film formation thus enhancing its environment friendliness.…”

Urethane acrylate hybrids are commonly used in polyurethane dispersions (PUD). PUDs are key ingredients in UV curing applications and UV curing is widely used in coatings and inks. The preparation of PUDs involves many volatiles in the form of solvents and reagents that are also carried over in the UV curing step. This article reports a process, which totally eliminates these volatile components and additionally introduces many flexibilities. The process involves acid–base interaction between tertiary amine containing polyurethane and acidic vinyl monomer like acrylic acid forming polyurethane‐acrylate (PU‐AA) hybrids in water. The developed process also overcomes the prepolymer and “endcapping” approaches used in the preparation of PUDs that restrict the molecular weight of polyurethanes. Simultaneously, because of the prevalence of large number of vinyl components in the polymer backbone through the acid–base interaction, it functions as a multifunctional acrylate similar to the reactive diluents used in UV curing applications. Thus, it helps to increase the cross‐linking density of the UV cured substrates. In general, high crosslinking density helps to improve characteristics like hardness, scratch, solvent and stain resistance of coated substrates. The process has been demonstrated to form transparent and opaque coated substrates and cured inks. This development potentially helps to shift the process from an industrial activity to do‐it‐yourself domain and has implications for the development of components for 3D printing sustainably.

“…Different natural dyes obtained from by-products were also able to functionalize textile fabrics with high antioxidant activity. Among others, wool fabric dyed with S. sebiferum fallen leaf extract, silk fabric dyed with tea stem waste extract, and viscose fabric dyed with orange peel extract showed antioxidant activity above 90% [67,73,85,105,121,127].…”

Textile dyeing is known to have major environmental concerns, especially with the high use of toxic chemicals. The use of alternatives such as natural dyes rich in phenolic compounds has become extremely appealing in order to move towards a more sustainable circular economy. Phenolic dyes have the potential to functionalize textile fabrics with properties such as antimicrobial, antioxidant, and UV protection. Wastes/residues from the agri-food industries stand out as highly attractive sources of these compounds, with several by-products showing promising results in textile dyeing through the implementation of more sustainable and eco-friendly processes. This review presents an up-to-date exploration of the sources of phenolic compounds used in the textile industry over the past two decades, with a primary focus on the functional properties they provide to different fabrics. The research highlights a surge in interest in this theme since 2017, accentuating a noticeable upward trend. Throughout this review, emphasis is given to by-products from the agri-food industry as the sources of these compounds. The reviewed papers lay the foundation for future research, paving the way for exploring the potential of raw materials and by-products in the creation of functional and smart textiles.
