------------------------------------------------------------------------***------------------------------------------------------------------------ABSTRACT The Comprehensive focus on plant Based extract in textile coating as textile finish. This study deals with extraction of Neem (Azadirachta indica) leaves using water and methanol. The Neem (Azadirachta indica) have been applied to cotton and as well as on Bamboo fabric in presence and absence of free formaldehyde crosslinking agent (Glyoxal) using Pad-Dry-Cure method. Antimicrobial properties of treated fabric have been improved which make it more important and inevitable finish for Garments. The Azadirachta indica treated fabric exhibited antimicrobial activity against both Gram negative and Gram Positive Bacteria. The Treated cotton and Bamboo fabric have shown an excellent antimicrobial activity. The sample were examined of cotton and Bamboo including, Colour Strength Value and also the treated fabric show very good results for UV protection. The novel feature of this study was the use of SEM and FT-IR spectroscopy to identify the major chemical groups in the extract as well as its attachment on cotton and bamboo. Keywords: Azdirachta indica leaves, Ecofriendly antimicrobial finishing, Herbal extract, cotton and Bamboo fabric.
1. INTRODUCTION Azadirachta indica commonly known as “Neem” belongs to Meliaceae botanical family and being abundantly available in nature. The principal constituents of these leave include protein (7.1%), carbohydrates (22.9%), minerals, calcium, phosphorus, vitamin C, carotene etc. An extract from the leaves can be prepared as an alcoholic tincture or as tea and this alcohol extract has a dark green colour. The chemical composition of the extract contains glutamic acid, tyrosine, aspartic acid, alanine, praline, glutamine and cystine like amino acids, and several fatty acids (dodecanoic, tetradecanoic, elcosanic, etc.). But physically the Azadirachta indica leaves have a pleasant odor and plant pigments like chlorophyll mainly responsible for green colour [1-3]. The Azadirachta indica extract is reportedly officious against a variety of skin diseases, septic sources and infected burns. The most important quality of these compounds is that they are less toxic to warm blooded animals like human. Thus, considering its less toxicity and effectiveness against microorganism, it is expected to be one of the safest and most effective colourant cum antimicrobial agent for textile [4-6].
