Study on the Hydrophobicity and Antibacterial Activity of Silica Sol-Chitosan-HDTMS Treated Cotton Fabric Dipped in an Aquas Media

A hydrophobic surface with an antibacterial property has numerous uses, including self-cleaning, anti-sticking, anti-contamination, sports apparel, and wound healing/implant materials. The durability of the coating in aquas media (pH 7.4) is a vital requirement for use technical textile sectors, particularly medical applications. In this study, we used silica sol, chitosan hexadecyltrimethoxysilane (HDTMS) to create exceptionally surfaces properties on cotton fabrics. First, fabric was treated which produced by hydrolysis condensation tetraethoxysilane (TEOS) alkaline environment. After that, applied sol-treated add characteristic. sol-chitosan-treated then given hydrolysed HDTMS treatment give highly property. hydrophobicity assessed measuring water contact angle, while AATCC-147 test protocol assess developed exhibited strong samples were immersed 30 days observing changes anti-bacterial activity terms zone inhibition (ZOI). immersion media, it observed that angle decreased from 151.7° 129.5°, ZOI increased 1 mm 5 mm, indicates increase relation time immersion. wicking characteristics coated uncoated fabrics also measured determine how affects behaviour fabric. EDS performed observe stability coated-dipped after days. SEM analysis examine morphology, FTIR functional groups dipping media. may help fabrication natural biomaterials other products.
