Epoxy thermosets need to be designed for simple recycling and biomass resource utilization in order to be fully sustainable building materials. The development of covalent adaptive networks (CANs) using adaptive covalent chemistry (ACC) may be helpful in this regard. Several reversible covalent bonds are incorporated into the epoxy polymer to overcome the challenge of reprocessability or recyclability, degradability and self-healability. The imine bond, also referred to as the Schiff base, is one of the reversible covalent bonds that can participate in both associative and dissociative reactions. This opens up possibilities for mechanical and chemical recycling as well as self-healing. This review summarises the progress related to the synthesis and mechanical and thermal properties of epoxy thermosets based on reversible imine bonds derived from different sustainable resources over the past few decades. The feedstocks, physical and thermal properties, recycling conditions, degradability and self-healability of the biomass epoxy thermosets are addressed along with the main obstacles, prospective improvements and potential applications.

The comfort behavior of textiles relies on the transfer of sensible and insensible sweat which can be obtained by improving the moisture transmission properties of knitted fabrics. This research investigates the impact of primary heater (PH) temperature (150°C, 170°C, 190°C, 210°C) on the structural properties like morphological changes, wicking, crystallinity, and comfort properties such as breathability and moisture transmission properties of 100% PET (Polyethylene Terephthalate) based knitted fabric made from draw-textured yarn (DTY). This study establishes a direct connection between yarn structure (crimp, mechanical characteristics, and morphological structure) and fabric performance (moisture management and permeability). The findings demonstrate that increasing the PH temperature to 190°C improves 19% crystallinity from 37% to 44%, promotes better textured and crimp structure, leading to enhance capillary pathways. Consequently, fabric produced at 190°C showed the best performance with overall moisture management capacity rising from 0.0897 to 0.7388 (>700% increase), one-way transport index reaching 306%, wetting time decreasing to 2.059 s, and absorption rate escalating to about 51%/s. Moreover, air and water-vapor permeability also improved by approximately 25%–30% compared to lower temperatures. However, increasing temperature to 210°C, comfort-related measures showed slight deterioration due to partial crimp relaxation and reduced inter-filament spacing. These results offer useful guidance for improving DTY processing conditions demonstrating that regulated PH temperatures (∼190°C) may greatly improve moisture transport and breathability of polyester knitted textiles for sports and functional clothing applications.
