Surface modification of nonwoven PET is very important due to its importance and application in various fields such as: hygiene, medical, filters, carpet backing, insulation and others.Polymer/layered silicate nano composites have been recognized as one of the most promising research fields inmaterials chemistry because of their unique properties, such as enhanced mechanical property, increased thermal stability, improved gas barrier property, and reduced flammability. In recent years nano titanium dioxide has attracted much attention as photo catalysts in special applications. This paperdescribes a method for surface modification of hollow fiber PET nonwoven using nano clay, nano TiO2 and poly siloxanesoftener through conventional exhaustion-dry-cure method.The effect of presence and absence of nano clay on the fabric surfaces modification was investigated. Thermal stability and mechanical strength of the treated fabrics were also investigated.
