Abstract
In this study knitted single jerseysamples by polyester microfiber (150/288) yarn countwere manufactured. Threedifferent machines gauge (20-24-28) was performed. The polyester knittedfabrics were treated with nano clay and nano silica with twoconcentrations (1.5% &3%). The samples specifications as stitch length, stitch density and tightness factor were measured while weight, thickness, bursting, UPF, air permeability and stiffness properties were tested.The treated polyester samples dyed with dispersing dyes and the fastness properties were carried out. Furthermore, FTIR was determined to characteristics the modified fabrics and the moisture regain% of samples was estimated. The result presented that the nature of nano treatment plays a striker role in the functional properties of knitted samples as well as although the result referred to improving in samples characteristics and the air permeability were detected. In addition, depending on the radar area, nano silicon dioxide more effective than a nano-clay treatment with different concentrations and the knitting machine gauge (24) offered the highest rating.
