Abstract :
We treated wool textiles with a sulfur nano-silver
colloidal solution (SNSE) having Ag/S complex, which
was a particle size of average 4.2 nm in ethanol base. The
SNSE was a safe chemical agent having the perfect antibacterial
efficacy with a very small amount of nano-sized
silver and non-irritative solution to the skin. Antibacterial
activity was evaluated by calculation of bacteria reduction
against Gram-positive (Staphylococcus aureus) and Gramnegative
(Klebsiella pneumoniae) bacteria. The treated wool
textiles with the silver colloid were investigated the resistivity
against insect pests through both calculation of the
fiber loss weight and visible assessment attacked by larvae
after 14 days in given conditions. Also, we confirmed the
antistatic efficacy of the finished fabrics with silver particle
on their surface. The static electricity of the treated wool
fabric was increased more up to 50 ppm, then, it was decreased
according to the silver content. Consequently, it was
demonstrated that the finished wool fabrics with sulfur nanosilver
colloid had various functionalities, such as mothproofing,
antibiotic, and antistatic property.
