Effect of polyurethane crosslinker, fluorocarbon and silica NPs on water/oil repellency and mechanical properties of cotton fabric

This paper focuses on the effects of Crosslinker CPN and silica NPs with fluorocarbon (FOBUGARD AF300) on repellency and mechanical properties. In order to achieve this purpose, the crease recovery angle, oil and water repellency rating, tensile strength and abrasion durability was evaluated. FESEM and EDX were used for the assessment of morphological properties, size distribution and elemental analysis of fluorocarbon/silica NPs coated fabric. The results showed a good repellency. However, there is an optimum range silicaNPs concentration in order to achieve a hydrophobic rough surface. Additionally crease recovery angle was enhanced. Also silicaNPs enhanced abrasion resistance.
