Purpose: Protection of medical personnel against pathogenic viruses is a challenging task for the world scientific community. The purpose of this paper is to collect, analyze, critique, rearrange and present the scattered information scientifically to form a base for product development for viral protection. Design/methodology/approach: A huge range of recently available information has been collected, studied and arranged judiciously. Findings: After an exhaustive study of this topic, it is possible to present all information in a manner that will be helpful to start product development activity on both sides of the Atlantic. Initially, various coated textiles with zero breathability were used to cover doctors, nurses and staff but thereafter microporous coatings replaced the poreless surface coatings. However, the pore size distribution in microporous films and coatings could not be controlled precisely and manufacturers could not claim the surface offered foolproof protection against viruses. Monolithic films are able to claim guaranteed protection against virus penetration, with sufficient breathability. Monolithic film technology has prime importance in protective clothing that has to be discussed judiciously. Permeability of block copolymers based monolithic films is an important feature for barrier materials, high performance impermeable breathable clothing and membrane separation processes. Originality/value: This is a first paper in the field of viral barrier fabrics which will remain helpful to the scientific community to start further research work and product development. © Emerald Group Publishing Limited.

Ascorbic acid and fructose react in an aqueous alkaline solution at temperature below 50°C in a Maillard-type reaction to from brown coloured end products. The kinetics of browning of alkaline solution of fructose in presence of ascorbic acid has been studied by measuring the absorbance of browning development in the reaction. The development of brown colour due to heating of either reducing sugar alone or ascorbic acid alone in the presence of alkali is found to be very slow even at high temperature (~70°C). However, in the presence of ascorbic acid the development of brown colour due to heating of alkaline fructose is sufficiently fast even at low temperature ~50°C. The rate of development of colour (browning reaction) has been found to be first order dependence with respect to [alkali] and [fructose] and fractional order dependence with respect to [ascorbic acid] at low concentrations of ascorbic acid. A mechanism consistent with the observed kinetic data has also been proposed.

The golden fabric jute is a plant which yields a fibre used for sacking and cordage.All across the world, jute is one of the most versatile fabrics gifted to human being by nature that has several uses in the form of handicrafts. It is the cheapest and importanttextile fibre after cotton. Jute can be exemplified as a golden natural fibre with versatile application aspects ranging from low value geo textiles to high value carpet, apparel, composites, upholstery furnishings, decorative color boards, fancy non-woven for new products and many more. Due to its unique versatility and long lasting nature, jute is regarded as the Fibre for the Future. In coming era, variety of mini jute plants and jute mills will be seen engaged in the production of jute and jute blended yarns. These yarns arevery light weighted and are used in varied applications like in upholstery, furnishing, garments, bags etc.

Civil engineering and building industry are an integral part of the development of human society as they involve the planning, design, building, operation and maintenance of infrastructure. The venturing of technical textiles or highperformance textiles in this sector has given a great impetus to the quality of construction. These textiles are used in the construction of buildings, dams, bridges, tunnels and roads and collectively comprise the "Buildtech" sector. Geotextile textile product are the textile material applied under the soil. They are used for reinforcement of streets, embankments, ponds, pipelines, and similar applications. The basic geotextile functions include erosion control, protection, filtration, armoring, drainage, and separation or barrier function. Large number of textile employed in present day civil engineering works can be classified into geo membranes and geo textiles. Geo membranes are devoted to waterproofing linings of canals, reservoirs and earth filled dams. Geotextiles are designed for principal functions as drainage, filtration, separation, reinforcement, erosion control etc. 3D fabrics are the focus of rapid development due to their versatile physical, structural attributes and application scopes. These fabrics can be produced in various architectures which offers a great deal of opportunity to modify the properties such as shear strength, dimensional stability, damage, tolerance, and fracture toughness that are critical for many structural applications. 3D-woven textiles exhibit higher through thickness and inter laminar properties because of their integrated structure. This paper highlights the various designing preforms of 3D woven structures for geo textiles on conventional looms and their application in context with Buildtech & geotextile. © Research India Publications.
