“…The lower section is characterized by a mesh‐like structure, as well as being polluted and possessing a rigid texture. Following the process of softening, 52 the mesh‐like section exhibited a reduction in its structural integrity, hence posing challenges in discerning the individual fibers comprising it. Therefore, in order to make yarn, just the central segment of the stem was utilized for spinning, as depicted in Figure 1A.…”

Contemporary researchers are directing attention towards enhancing the structural integrity of biodegradable matrices, such as polylactic acid (PLA), through the incorporation of plant fibers. The utilization of novel fibers is becoming more prevalent to achieve the specific demands of composite applications, particularly in the automotive and packaging fields. Woven fabrics are commonly favored for reinforcing composites due to their elevated specific strength and dimensional stability. In pursuit of this context, we have developed a unique woven fabric using 100% okra fiber and utilized it in the production of PLA biocomposites. This approach was made due to the unexplored potential of okra woven fabric in the field of composite manufacturing. To optimize the performance of the composites, three distinct weight proportions of okra woven fabric (OWF) were chosen, including 20%, 30%, and 40%. The obtained composites were mechanically, morphologically, and thermally characterized. The manufactured composite's maximum tensile and thermal property was attained by adding 20% OWF to the PLA. Scanning electron microscopy analysis revealed that 20% OWF composite possessed superior fiber‐matrix adhesion, improving all properties' efficacy. The overall findings reveal that the OWF/PLA composites are promising as a green material for applications in the automotive and packaging industries.Highlights A novel class of composite has been created using 100% okra woven fabric. The composite with 20% fabric content showed the best mechanical properties. Thermal properties of composites are also optimized using 20% fabric content. SEM confirms the strong fiber‐matrix bonding of 20% OWF/PLA composites. The composites are suitable for automotive and packaging applications.

This article focuses on comparing the characteristics of cotton fabric dyed with Diospyros mollis extract (DME) solution and that of cotton fabric dyed with the reactive dye. The parameters of the cotton fabric after dyeing with both types of dyes were assessed, including color strength (K/S), structural morphology, infrared spectrum, antibacterial properties, UV resistance, color fastness to washing, rubbing, light, moisture absorption, breathability, and wastewater indices. The obtained results show that the K/S value of cotton fabric dyed with DME solution is slightly lower than that of cotton fabric dyed with the reactive dye, 18.52 and 19.36, respectively. The cotton fabric dyed with the reactive dye does not exhibit antibacterial activity against Escherichia coli and Staphylococcus aureus, whereas the antibacterial effectiveness against these bacteria for cotton fabric dyed with DME solution is 99.99 %. The UV protection capability of cotton fabric dyed with DME solution is superior to cotton fabric dyed with the reactive dye. The BOD/COD ratio of wastewater from the dyeing process with DME is higher than that of the reactive dye, with values of 0.70 and 0.32, respectively. The findings of this study indicate the superior ability of using DME solution as compared to the reactive dye, which is promising as a natural dye for fabric in medical applications.
