Background: The integration of electronics into textiles necessitates the development of highly conductive, flexible, and durable conductive yarns. Traditional metal-based conductors lack flexibility, while carbon-based materials often require complex processing.

Objective: This study aims to synthesize and characterize a novel conductive yarn by coating cotton substrates with Titanium Carbide MXene (Ti₃C₂Tₓ) nanosheets for applications in wearable sensing and electromagnetic interference (EMI) shielding.

Method: This study uses a simulated dataset created for academic training purposes. MXene nanosheets were synthesized via selective etching and deposited onto cotton yarns using a dip-coating technique. The yarns' electrical conductivity, mechanical properties, and EMI shielding effectiveness (SE) were evaluated using simulated data based on established theoretical models and literature benchmarks.

Key Results: The MXene-coated yarn exhibited a linear electrical conductivity of 125 S/cm, a 40% increase in tensile strength due to nanosheet reinforcement, and an EMI SE of 35 dB in the X-band frequency range. The coating demonstrated excellent stability after 1000 bending cycles.
