Area of Science:

• Biomaterials Engineering
• Textile Science
• Nanotechnology

Background:

• Textile-supported nanocomposites are crucial medical scaffolds for tissue support.
• Fabricating these composites faces challenges like pore size control, minimal skin contact, biocompatibility, and material degradability.

Purpose of the Study:

• To synthesize and optimize polyamide-6 (PA) nanofibers for textile composite fabrication.
• To develop and evaluate fabric-supported nanocomposites using PA nanofibers and various textile structures.

Main Methods:

• Polyamide-6 (PA) nanofibers were produced via optimized needleless electrospinning.
• Optimized nanofiber membranes were integrated with woven, non-woven, and knitted fabrics.
• Composites were analyzed for mechanical properties, morphology, structure, and chemical interactions, comparing them to market meshes.

Main Results:

• The developed nanofiber/woven composite showed three times higher tear strength than market woven mesh.
• The nanofiber/knitted composite exhibited 2.5 times higher tear strength than market knitted mesh.
• Enhanced bursting strength, tensile strength, and puncture resistance were observed in the developed composites compared to market meshes.

Conclusions:

• The synthesized PA nanofibers and textile structures form multifunctional composites.
• These novel composites demonstrate superior mechanical properties suitable for medical scaffold applications.
• The findings indicate potential for PA nanofibers/textile structures in advanced biomedical applications.
