“…Some of these compounds are absorbed through chemical protective clothing permeation, the skin barrier and the viable epidermis followed by distribution into the blood capillaries resulting in systemic poisoning. Nanotechnology based materials are investigated for providing protection to military personnel ( [3]). Contrary to controlled release technologies, efforts are devoted to developing a strong barrier to prevent the absorption of chemicals.…”

The effects of mechanical properties and chemical affinities of materials on the transport of solutes were studied. Simulations show that the kinetics of permeant fluids in matrices depends on the rheological and chemical properties of the polymer. Fick's law failed to describe transport through viscoelastic materials because of the force exerted on the incoming fluid causing a delay. Reversible binding to immobilizing sites also retarded permeation of molecules. An integro-differential equation was applied to model transport in the presence of solute membrane interactions. While the differential part of the equation was represented by an elliptic operator, the integral part, composed of two integrals, described the contributions of stress and reversible binding. Using Laplace transforms, the steady-state flux and effective time constant were calculated. The latter parameter represents a statistical interpretation of the waiting time to achieve equilibrium in the system. The lag time, that defines the first moment when a detectable concentration is measured in a receiver cell, was also studied using multiple integration. Subsequent analyses revealed the dependence of the steadystate flux, the effective time constant, the lag time on the Young modulus, the viscosity and the binding/unbinding rates. The results presented in this paper make it possible to tune the mechanical and chemical properties to achieve a desired transport profile.

“…Most of reported research works based on nano-fibre is carried out on conventional electrospinning set up using principle of disintegration theory of CWA [9][10][11][12]. Such set up consists of syringe and needle having limitations of practical application in terms of obtaining uniform quality webs, durability, lower specific strength and very lower throughput rate (0.1-1.0 mL/h) and that is also for applying either in sound absorbing materials, aerosol and water filtration, wound healing and biomedical fabrics [2, [9][10][13][14][15][16][17][18][19].…”

Abstract:The process of designing protective military clothes is a long process based on the application of new generation of materials and searching for new trends in the fi eld of protective clothing. The fi rst step in the process of designing protective clothes includes the entire design activity for new products development with special emphasis on the applying of the types of new high-performance fi bers for protection of the soldiers. The right selection of materials means better protection and higher satisfaction of both, the wearer and the technologist.In this paper the main characteristics of the fabric materials used in protective clothes design are presented and the selection of the best materials for the required level of protection is made. The selected materials for design of protective clothes are analyzed and their main characteristics are presented. It is also clear that the armour should be as comfortable as possible and appropriately light.
