Abstract: The choice of aesthetic properties as well as the functional properties of textile products is increased extensively day by day to the customers. That's why, new technology is developed in different areas of technical textiles to fulfill the satisfaction of customers. Nanotechnology is one of the most important areas, which is increasing significantly at the present time. Various types of high performance textiles are produced now a days by different finishing, coating or manufacturing technique of producing fibres or fabrics as well as nano sized (10-9m) particles are imposed on finished clothing. This nanoengineered textiles cover from the protective clothing, smart textiles , hygiene textiles, antiballistic or bullet proof vest or functionally finished clothing like water repellent or wrinkle resistance clothing.........
Keywords: Nanotechnology, nanofinish, functional textile, high performance clothing, smart textiles.

Abstract: Pandanus Odorifer (PO) fibre species were treated with varied concentrations (2 - 20%) NaOH at room temperature for 1 h and physical properties were evaluated. Chemical composition of the treated fibres showed that hemicellulose was removed to a varied extent by mercerization. Tensile strength of the treated fibres, their moisture content, surface morphology (by Scanning electron microscope), crystallinity index by XRD analysis and thermal degradation (TGA) were analysed. The alkali treated fibres between 2 to 15% showed all round improvement in the properties as compared to with those of untreated raw fibres.

Abstract: Now a day's plastic places a vital role in the field of automotives, which needs a good impact property at a reasonable cost. ABS and PLA materials has been mixed in an appropriate proportion of 90:10, 80:20, 70:30 (wt%) and a suitable compatibilizer i.e. glycerol, is also incorporated in to that mixture at a percentage of 2%. Then prepared the blend by melt blending using twin-screw extruder. After blending compatibility was investigated by DSC. The ABS-PLA blended materials were tested to find the mechanical, thermal and electrical properties...............

Abstract: Two compounds of stearoyl chitosan; degree of substitution (DS) 79% and DS 86%, were synthesized by using the starting material as chitosan and deacetylated chitosan respectively. Fourier transform infrared (FT-IR) and Nuclear Magnetic Resonance (1H NMR) spectroscopy were used to confirm the chemical structure of prepared products. The thermal stability of stearoyl chitosan decreased with increased DS while the DO (degree of order) increased with increased DS. The 2% (w/v) stearoyl chitosan (DS 86%) solutions displayed shear thinning behavior..............

Abstract: Cornhusk fibres were extracted with step-wise treatment using alkali, enzyme and bleach. The extracted fibres were analysed for various physico-chemical parameters. The alkali treatment was optimized with respect to concentration of sodium hydroxide, temperature and time of treatment. The extracted fibres as the fibres obtained in optimum conditions had strength and fineness as 1.59 g/denier and 130 denier respectively. The fibres after final bleaching treatment had bundle strength of 1.33 g/denier and fineness of 86 denier. Bleached cornhusk fibres were composed of 76% cellulose..............
