Abstract


A technical textile is the emerging area it represents a multi-disciplinary field with numerous end use applications. Technical textiles are high performance, special textile materials and products that are manufactured primarily for their technical and performance properties rather than their aesthetic or decorative properties. In the recent years, Comfort has become mandatory in medical textiles. Textiles with Multifunctional Finishes – Coolant and Antimicrobial Finishes are given to provide comfort to the human beings. Studies have been carried out in the present work to fine- tune the properties of thermal comfort and resistance to microbial attack particularly to Human eye. The development of eye pillow with Coolant and Antimicrobial effect of finishes are achieved by using a selected eco friendly medicinal herb -Glycyrrhiza glabra (Yashtimadhu) roots. The extraction of the herb is done by direct extraction method by using distilled water as the selected solvent among the other solvents like methanol, ethanol, chloroform, acetone and distilled water and it is applied on to the cotton fabric by pad – dry – cure method in an optimized process conditions.The treated and untreated samples are tested in a standard testing method like ISO 11092- Thermal resistance, Wettability, Wickability, SEM, FTIR and Antimicrobial tests – AATCC 100, AATCC 147, AATCC 30 Agar Diffusion and Broth Dilution test .. the results indicate that treated fabric with 50% concentration of Glycyrrhiza glabra have high thermal resistance coolant and antimicrobial activity and it showed good resistance to washing up to 12-18 cycles.
