چکیده

 The opaque cotton / nylon fabric that is often used in military clothing should have unique properties to
enhance the efficiency and ability of individuals. Therefore, creating properties such as waterproof,
antimicrobial, fire retardant, etc. on the product is considered, which can be achieved by using nanoparticles
on the product in small quantities. As a cheap mineral, with thermal and optical stability, clay nanoparticles
have many absorption properties and can be used to complete textile goods. In this paper, a 5% solution of
montmorillonite nano-clay was applied on a cotton / nylon cloth (50/50) by pad-dry-curing method (at 160 °
C for 10 minutes) and then the product properties included The bleaching, dyeing, fire retardant, wash stability,
optical stability and UV resistance properties were investigated.
The results of dyeing test using two dyes of methylene blue (cationic) and direct dye class B (Blue218)
(anionic) and performing uv-vis test on their effluent showed that the use of nano-clay on cotton / nylon fabric
It can create more space for dye adsorption and allows more dye to be involved in the nanoclay layers, thus
increasing the dye adsorption by the fabric and, consequently, increasing the decolorization capacity in the
effluent. Also, the presence of nano-clay on this fabric increases the washing stability, optical stability, fire
resistance and UV protection.
