This paper is aimed to prepare and characterize super-hydrophobic nylon-6 woven fabric by using silica nanoparticles, coupling agent 3-aminopropyltriethoxysilane (APTES), and a long chain hydrophobic agent hexadecyltrimethoxysilan (HDTMS). Synthesize of silica nanoparticles is processed with a modified Stöber method resulting in a mono- dispersed particle whose diameter is 51-60 nm. In this experiment chemical bonds presenting over the surface silica nanoparticle are Si–CH3 and Si-OH Due to the reaction between the hydrolyzed APTES and the first layered surface, the Si-OH group is spectra onto the surface. The hydrolyzed HDTMS molecules created a bond to the surface by the formation of Si–O–Si bonds. As result, a long chain of organo-silane with low surface free energy is introduced onto the fabric surface. The hydrophobic coated surface appeared after spray coating with additional treatment without any adhesive. The super- hydrophobic nylon-6 woven fabric has been coated by spray method with static water contact angle 151.8֯. Characterization manifests a good self- cleaning tendency and low permeability difference. Keywords: Silica nanoparticles, Nylon-6 woven fabric, super-hydrophobic, coating, synthesis, Stöber method. I. INTRODUCTION Consumer demand for a comfortable and healthy lifestyle at the same time in one certain product has created the concept of multi-functional textiles. Hydrophobicity, air permeation, soil release tendency, and mostly lightweight clothes, etc. are in high demand of the market, and in current decades the attraction raises of hydrophobic or super-hydrophobic fabrics. Hydrophobic surfaces are characterized by a water contact angle of 90֯ to 150֯ and for super-hydrophobic is greater than 150 ֯ [1]. “Lotus leaf” which constitutes the hydrophobic epicuticular wax (decrease surface wetting) associated with the micro or nano-scale stratified architectures has made the concept of ultra-hydrophobic or super-hydrophobic [2]. Proper micro or nanostructures to create surface roughness and materials with low surface energy in a combined form can produce a super-hydrophobic
