Dressing Materials

The aim of this paper is to introduce novel dressing with Mikania Micrantha for quick blood clotting and wound healing. When epidermis of human skin is cut or scrapped, sometimes too much bleeding occurs. Excessive bleeding may cause death, if bleeding is not stopped immediately. To promote blood clotting & wound healing natural based bio materials are still insufficient in medical textile sector. To fill up this scarcity, woven fabric treated with Mikania micrantha leaf juice & leaf powder was examined. M. micrantha exhibits good blood clotting time in comparison with available dressing materials. Woven fabric (bandage) that contains M. micrantha can be used for cut wounds healing purpose. The experiments were carried out in environment friendly way which indicates the production & processing of these dressing materials can have enormous contribution to sustainable operations and products.

Knitted auxetic fabrics (AF) are in common practice but their stability and thickness are major problems in commercial applications. Therefore, a simple method of developing woven AF is proposed here. Differential shrinking property of different weaves is utilized to visualize auxetic honey comb geometry in fabric structure. Based on this fabric structure, auxeticity is induced in 2-D-woven fabric. AF is developed using conventional nonauxetic materials (i.e., cotton in warp and elastane [Lycra] yarn in the weft). Auxetic nature and auxetic structure in the fabric were characterized by microscope. Comfort properties (air permeability, thermal resistance, stiffness, and wicking) of AF were compared with conventional nonauxetic fabrics (NAF). Piezoresistive nature of conductive AF and NAF is also compared. AF showed superior comfort properties and higher sensitivity as compared to conventional NAF. Based on results, AF can be considered better replacement of conventional NAF in wearable and medical applications.

Spacer Fabrics

Nowadays, applications of spacer fabric cover wider areas of technical textile. It is used in the automotive textile, personal protective clothing, sports textile, foundation garments, pads for swimwear, buffer clothing, medical textile etc. It does possess good recovery to compression, high bulk with relatively lightweight and very good moisture permeability. Almost in all applications, spacer fabrics are compressed by different parts of human body. Body parts have different shapes and curvatures. In all standard methods, spacer fabric compressibility is measured by a pair of flat circular plate which cannot represent a human body. The contour of body can be assumed as cylindrical with varying radius of curvature. So, it is necessary to understand the mechanism of compression of spacer fabric with cylindrical surface in order to understand the performance of the fabric under real-world dynamics. In this research, an effort is being made to predict the compression behaviour of warp-knitted spacer fabric by flat as well as cylindrical surface. Finite Element Models were designed on Abaqus/CAE platform to meet above requirement with variable circumstances. Experimental setup was also made to analyse cylindrical and flat compression at different circumstances. Results show that flat compression and cylindrical compression are largely deferred in terms of shape of load-deformation curve and compressional energy. Effect of variables on compression behaviour was also analysed. Model results were validated with experimental values. It is found that the proposed model has got a good agreement with the experimental results.

Antimicrobial activity of essential oils obtained from many plants has been known for a long time. However, the use of essential oils as active components of biomedical textile have recently gained popularity and aroused scientific interest. The antimicrobial activity of two essential oils, Rosmarinus officinalis and Abies sibirica, respectively, was detected using two indicator strains: Staphylococcus aureus ATCC 25923 and Escherichia coli ATCC 25922, respectively. To achieve a controlled release of antimicrobial activity and to enable utilization of higher concentrations of active ingredient, the essential oils were first encapsulated in beads based on alginate, gelatin and yeast cells, and then bounded to medical textile. The maximum oil content (85.4%) was achieved in alginate capsules. The release of essential oils was followed by determination of viable bacterial cells during a seven-day incubation of beads in saline. Rosmarinus officinalis and Abies sibirica immobilized in the beads showed a significantly prolonged activity, with some gel-dependent variation.
