EDA Modified Polyester Fabric for Better UV Protection

The new textile application for achieving the materials for human performance (medical, protective and sports) is one of the guidance for future textile development in Europe. The present paper is an attempt to modify surface of polyester fabric with EDA (ethylenediamine) for achieving better UV protection. Polyester fabric protective ability from UV radiation (UV-R) was investigated after EDA and UV absorber treatment and optical brightening. Polyester fabrics of poly(ethylene-terphtalate) for summer clothing purpose was treated in EDA. Optical brightener Uvitex ERN-P (Ciba) was applied on polyester fabric surface by thermosol and UV absorber, Tinofast PES (Ciba) commercial product specially produced for UV protection in exhaustion method. UV protection was de&not ; ; termined using transmission spectrophotometer Cary 50 (Varian) according to AS/NZS 4399:1996 ; fabric whiteness (CIE whiteness, CIEWH) and yellowness (Yellow Index, YI) was determined using remission spectrophotometer SF 600 PLUS CT (Datacolor) according to DIN 6167:1980. For durability of treatment fabrics were washed according to ISO 6330:2000.
