Antibacterial finishing of nylon 66 fabrics was carried out with sericite and medilite which are a cheap price antibacterial agents and had excellent antibacterial effects. The particle size of sericite and medilite was 15 ${mu}m$ and 30 ${mu}m$. The antibacterial and deodorant ratio, tensile and tear strength, peel strength were examined to investigate the change of physical properties and antibacterial effect. The results are as follows. 1. Peel strength is increased with increasing adhesive content, and satisfied standard value of peel strength when adhesive content is 20 $g/m^2$. Also peel strength was decreased with increasing antibacterial agent content and particle size in the adhesives. 2. Tensile and tear strength were not related with antibacterial agent content in the adhesives. 3. Laundering nylon 66 fabric treated with antibacterial agent, the optimum content satisfying Korean Standard(KS) is 8%. The antibacterial and deodorant ratio were not affected by several types of adhesives.
