Determination of antioxidant capacity of capsule loaded textiles

In this study, microcapsules containing alpha-Tocopherol (alpha-TP) have been prepared by complex coacervation technique and applied to cotton fabric by padding method. Characterization of the capsules is determined by scanning electron microscopy, thermogravimetric analysis, fourier transform infrared spectroscopy and particle size measurement. Yield of microencapsulation process is found in the range of 41.63 - 62.20%. Antioxidant capacity of capsule loaded textiles has been examined according to DPPH free radical scavenging method, and alpha-TP existence in ethyl cellulose capsules is found as 65.218 - 330.722 mu M. alpha-TP activity in capsule treated fabric is determined as 61.73 mu g. Presence of the capsules on fabric and also alpha-TP activity has been found to remain effective even after twenty washes at 40 degrees C
