Abstract: Polyvinylidene fluoride, polyvinylidene difluoride or simply PVDF is a chemically stable thermoplastic fluoropolymer synthesized by the polymerization of vinylidene difluoride. Polyvinylidene fluoride (PVDF) is a piezoelectric polymer material which gives voltage as output when pressure or mechanical force applied on it. Based on this properties it is used in different sensing technology. There are different renewable sources present in environment like ocean waves, rain and wind. PVDF based piezoelectric nanogenerator can be a novel new kind of device which can generate power from all these renewable resources. In this article nanofiber based PVDF nanognerator has been prepared.Taken the output from finger pressure. Output power is mainly depend on the crystallinity and electroactive phase of PVDF . A brief idea about the improvement of crystallinity and electroactive phase is also described here.
Keywords: Polyvinylidene fluoride, piezoelectricity, electroactive phase, nanogenerator, energy

Abstract: This report is a followed up study of an earlier published work on Morphological Trends of Modified Coconut Fibre in Natural Rubber Reinforcement, where the Coconut Fibre was modified through the carbonization at varying temperatures of 300,400,500, 600, and 7000C for three (3) hours each. Evaluative examinations gave 6000C as the recommended best temperature at which significant performance of the composites could be achieved. In the present report carbonization was achieved at 6000C for a varying period of 1, 2, 3, 4 and 5 hours in order to evaluate the effect of carbonization time on the morphology and mechanical properties of the Coconut Fibre/Natural Rubber, composites...........

Abstract: Fiber identification is the most important things to design a specific purpose dress. In this study, different textile fibers are identified through both technical and non-technical test. Technical test can be microscopic and chemical test & non-technical test can be feeling and burning test. Technical test is more authentic than non-technical test due to its accuracy.

Abstract: This research was concerned with dye extraction from bark peel of Araucaria columnaris and with the application of this dye for cotton fabric. Dyeing without any mordant was compared with those obtained with pre-mordanting, simultaneous-mordanting and post-mordanting with alum and myrobalan. The cotton fabrics dyed with and without mordant were evaluated for their color strength (K/S) values. Furthermore, the colorfastness to washing, light, rubbing and perspiration was investigated, the results of which showed fair to good fastness. The antioxidant property of the dyed samples was determined by DPPH method. The results of DPPH assay were positive for all the samples, confirming that natural dyes extracted from Araucaria columnaris bark peel have potential applications for fabric dyeing and producing cotton fabric with efficient antioxidant property.
Keywords: Antioxidant, Araucaria columnaris, Color strength, Natural dye, DPPH.

Abstract: The concept of solubility parameters was applied in the study of modification achievable on polyethylene terephthalate. The amount of solvent retained and the level of swelling achievable was studied after the polymer was pretreated in ten organic solvents for 30, 60, 120, 300, 900 seconds at 30oC and 50oC respectively. The amount of solvent retained was determined by weighing using a 4 digit meter balance and recorded as mol/ kg. The results retained were plotted as a function of time and temperature. Optimum retention of the solvents were recorded within 120 seconds of pretreatment after which a desorption was obtained for all the solvents...........

Abstract: Water-borne polyurethane-acrylate (WPUA) oligomer was prepared via in-situ and anionic selfemulsifying method from Hexamethylene diisocyanate, polyether polyol, dimethylolbutanoic acid, and capped with 2-Hydroxyethyl methacrylate. Subsequently, UV-curable WPUA oligomers were used to prepare glass fibre reinforced composite materials with 2-hydroxyethyl acrylate as reactive diluent and Irgacure 500 as a photoinitiator and glass fabric for reinforcing. The possibility of obtaining glass fiber reinforced composite materials on the basic of water-borne polyurethane-acrylates is of great interest to researchers due to the expected properties...........

Abstract: Pilling and abrasion are very important factors that affect the knitted fabric property greatly. In this experiment, 30 Ne carded and combed yarns were used to make single jersey knitted fabric. Then abrasion resistance and pilling tendency were checked for both fabrics made from carded and combed yarn. For pilling, ISO 12945 – 1 & ISO 12945 – 2 methods and for abrasion, ISO 12947 – 2, 3, 4 methods were conducted. Finally, it has been found that abrasion resistance and pilling performance are lower in fabric (carded yarn) than in fabric (combed yarn).
