In this study, silk and lyocell fibers are blended in the ratio of 50:50 and used in warp and weft directions for the construction of a plain weave fabric. Aloe vera based microcapsules have been used to impart antibacterial finish and its performance on silk/lyocell blended fabrics have been assessed by scanning electron microscope, electron dispersive x-ray, fourier transform infrared spectrum, agar diffusion test, bacterial reduction test, and durability against washing. SEM analysis shows that the aloe vera capsules are impregnated in the fabric. EDX also proved the presence of aloe vera in the fabric by showing the presence of chemicals like Mg, Ca, K, Al and Fe which are not present in the untreated fabric. FTIR spectra of aloe vera treated samples showed an ether group, an alcohol secondary group, an aromatic group and a nitro group which shows the probable chromophoric groups likely to be present in the leaf, gel and root of aloe vera. The results of agar diffusion test clearly showed that aloe vera treated S/L 50:50 blended fabrics have very good antibacterial properties and do not allow the growth of bacteria under the treated fabric. The zone of inhibition was found to be very good and ranged from 28 mm to 30 mm. Bacterial reduction test showed the percentage reduction values of both the microorganisms S. aureus and E. coli to be more than 97%. The wash durability of aloe vera treated fabrics lasted up to 25 washes.

Certain investigations on the thermophysiological and tactile comfort properties of silk/lyocell blended fabrics have been carried out. A series of yarns were produced as 100% silk (S 100), 75% silk and 25% lyocell (S/L 75:25), 50% silk and 50% lyocell (S/L 50:50), 25% silk and 75% lyocell (S/L 25:75) and 100% lyocell (L 100) and converted to woven fabrics keeping the same fabric set. FTIR study on silk, lyocell and silk/lyocell blended fabrics show the characteristic functional groups for the respective fabrics. The effects of blend compositions on thermophysiological and tactile comfort properties were examined and the results show that thermal resistance of the fabrics containing silk has a higher value in comparison with lyocell-rich blends. Water vapour permeability, absorbency and wickability for lyocell and lyocell-rich blends are found to be superior as compared to 100% silk fabrics. With respect to drape, bending length and crease recovery the lyocell rich fabrics are good in comparison with 100% silk fabrics. The results are discussed using one way ANOVA with 5% significant level. Keywords: silk, lyocell, blending, comfort, eco-friendly.
