Nano-biocarbon (NBC), known as Nano-biochar, is light in weight, brittle, and is used in textile and yarn applications, but the documented reports of its applications are few. This research aims to study the effect of NBC treatment on 100% polyester fabrics using immersion and investigate the physical, optical, and mechanical properties. NBC was prepared from the pyrolysis of wood wastes of the Schinus terebinthifolius tree in the presence of limited oxygen and then subjected to an ultrasonic device to obtain a nanoscale NBC. After that, analysis of NBC by X-ray diffraction (XRD), Fourier transforms infrared spectroscopy (FTIR), Scanning electron microscope (SEM), and Energy Dispersive X-ray spectroscopy (EDS) mapping was performed. Nine samples of 100% polyester fabric were produced with weave structures (plain1/1, twill 6/6, and satin 6) with picks/cm (20, 25, and 30) for each weave structure which all were measured for mechanical properties (tensile strength and elongation) before and after treatment. Three samples of the three weave structures at 30 picks/cm were measured before and after treatment for the physical properties of contact angle. One sample of twill fabric at 30 picks/cm was investigated before and after treatment for crystallinity by XRD, surface morphology by SEM, and optical properties by FTIR and ultraviolet (UV). Results of NBC analysis showed that it contained many smooth pores and functional groups, an increase in tensile strength, elongation, crystallinity, peak intensity, and change in the behavior of fabrics on exposure to UV of the treated fabrics.
