T hermal Stable and Self-Clean ing Hollow Fiber PET Nonwoven Usin g Nanoclay/Nano Ti O۲/Poly Siloxane Composites

Surfac e modification of nonwoven PE T is very important due to its importance and application in various fields s uch as: hygiene, medical, filters, carpet backin g, insulation and others. Polymer/l ayered silic ate nano composites have been re cognized as one of the most promising research fields in materials ch emistry bec ause of their unique pr operties, such as enhanced mechanical propert y, increased thermal sta bility, improved gas barrier propert y, and reduc ed flammability. In recent years nano titanium dioxide /nano clay composites has attracted much attention as photo cataly sts in special applicati ons. This p aper describes a method for surface modification of hollow fiber PE T nonwoven using nano clay, nano TiO۲ and poly siloxane softener th rough conventional exhaustion-dry -cure meth od. The eff ect of presen ce and absence of na no clay on the fabric surfaces m odification was investi gated. Therm al stability and mechanical strength of the treated fabrics were also inv estigated [۱-۴].
