“…Chemical surface modication can activate hydroxyl groups, which can create a strong bond with the resin. 297,433,434 Effective modication is done through debonding of the hydrogen structure in the bre, thereby enhancing the surface roughness of the bre. 400 The chemical treatment process removes impurities and hemicelluloses on the bre surface and enhances the reactivity of the hydroxyl groups with the coupling agent.…”

“…The most promising strategies for achieving above mentioned are fibers' modification and/or functionalization. Among many others, alkali (Ammayappan et al 2020;Gupta 2020;Wanget al 2019) and oxidative (Ibrahim et al 2010;Khan et al 2015) modifications still represent the most common routes for jute fibers' chemical modification. They provide selective hemicellulose or lignin removal, and therefore, obtaining cellulose-rich fibers with improved mechanical, thermal, electrokinetic, and sorption properties.…”

The electro-physical properties of raw and chemically modified jute fabrics were studied as complex phenomena of the interaction between the fabrics’ chemical composition, crystallinity, moisture sorption, COOH group content, structural characteristics, and frequency of the electric field. At 80% relative air humidity, all chemically modified jute fabrics have 38–179% and 1.7–5.4 times higher dielectric loss tangent and effective relative dielectric permeability compared to unmodified, respectively. To further improve these properties, fabrics were treated with CuSO4 and Cu-based nanoparticles were in situ synthesized on their surface by reduction. A few single Cu-based nanoparticles were observed across the alkali modified fabric’s surface, while single and agglomerated nanoparticles were distributed over the oxidatively modified fabric’s surface. No matter whether metallic Cu or copper oxide (Cu2O or CuO) nanostructures (or their mixtures) are synthesized (proven by XRD), excellent fabrics’ effective relative dielectric permeability is guaranteed. In other words, during the exploitation in specific conditions contributing to copper reduction, the jute fabrics will be able to store 21–163 times more energy from an external electric field than before the exploitation, which further extended their lifetime. On the other hand, with increasing the total content of Cu after the reduction and formation of single and agglomerated Cu-based nanoparticles, the movement of jute structural components’ molecules becomes difficult resulting in lower energy dissipation within the chemically modified than within unmodified fabric. Applied chemical modification and coating with Cu-based nanoparticles enables designing fabrics with predictable electro-physical properties, which is very important from the application point of view.

Ramie is a widely used plant fiber for making textiles and reinforcement in biodegradable composites. Pretreating cellulosic fibers with alkali before producing composites is increasingly used to enhance adhesion with polymeric resin. In this work, response surface methodology (RSM) based on the Box–Behnken technique was utilized to investigate the impact of independent variables on ramie fabric characteristics and determine the optimal treatment condition. The impact of alkali concentration, treatment time, and temperature on the breaking load and elongation at break of woven ramie fabrics were evaluated using Design‐Expert software, which established the design matrix and analyzed the experimental data employing numerical and graphical optimization methods. Moreover, the impact of alkali treatment conditions on the surface morphology, structural change of ramie fabrics, and thermal properties was investigated. Based on the analysis of variance (ANOVA) results, the suggested quadratic models can adequately predict the breaking load and elongation at break of the ramie woven fabrics within the range of conditions applied in this investigation. The RSM revealed that an alkali concentration of 6.12%, a treatment time of 30 min, and a temperature of 39.13°C resulted in an optimum treatment condition with a breaking load of 518.28 N and elongation at break of 23.36%.
