Plasma treatments are gaining popularity in the textile industry due to their numerous advantages over conventional wet processing techniques. In this study, nonwoven fabrics spunbond polypropylene, polyester basis weight of 25 g/m 2 and microporous PTFE film were used to develop tri-laminate antiviral surgical gown. The outer layer of spunbond polypropylene was treated with plasma enhanced fluorocarbon. The plasma treated polypropylene was also treated with titanium nano dispersion finish in a single bath pad-dry-cure method. The pore sizes of nonwoven fabrics were characterized using tri-nocular microscope. The titanium nano finished polypropylene was characterized by scanning electron microscope. The tri-laminate surgical gown was developed with outer layer of plasma treated polypropylene, middle layer of PTFE and inner layer of polyester nonwoven. Liquid barrier properties of surgical performance were analyzed by viral penetration, antibacterial, spray impact penetration, hydrostatic resistance, tensile properties and moisture vapour permeability to estimate their suitability for antiviral surgical gown. It is observed that plasma treated gown shows 99.04% bacterial reduction as compared to untreated, thus providing barrier against microbes. The plasma treatment does not alter the weight and tensile properties of surgical gown. The developed plasma enhanced flurocarbon treated tri-laminate surgical gown offer sufficient liquid barrier properties for level 4 protection as per Association for the Advancement of Medical Instrumentation classification. Moisture vapour transfer rate of plasma treated tri-laminate gown decreased by 21% in comparison with untreated nonwoven gown.

Background: Healthcare workers' uniforms including surgical gowns are used as barriers to eliminate the risk of infection for both doctor and patient. The prevalence of human immunodeficiency virus, hepatitis B and C viruses in the patient population is very common. Objectives: To develop antiviral surgical gown comprising of Polypropylene nonwoven as outer layer, Polytetrafluroethylene (PTFE) film as middle layer and polyester nonwoven as inner layer and the surgical gown with a basic weight of 70 g/m

HIV and hepatitis B and C are prevalent in the healthcare patient population. To provide a surgical gown protective against the prevention of viral and blood borne diseases is essential in healthcare today. The aim of this research was to develop a tri-laminate surgical gown comprising of polypropylene nonwoven (outer layer), polytetrafluoroethylene film (middle layer) and polyester nonwoven (inner layer). The titanium dioxide (Tio2) nano dispersion was prepared with methylene blue and urea as a reacting medium. These nano particles have an average size of 9 nm which was revealed by high resolution transmission electron microscope. The polypropylene nonwoven fabrics were treated with nano dispersion by pad-dry-cure method and tri-laminate fabric was formed using a fusing machine. The presence of nanoparticles on the surface of the nonwoven fabric was confirmed by a scanning electron microscope. The tri-laminate surgical gown passes the ASTM 1671 of viral penetration test. The fabric has been tested for the tensile, tearing, puncture resistance, seam strength and moisture vapour permeability which is required in healthcare.
