Natural plants extract for antimicrobial of textile finishing is a vital and potential area of current and future aspects therefore has greater market value. Cotton has long been recognized as media to support the growth of microorganisms such as bacteria and fungi. Among all the natural antimicrobial agents the plant products comprise the major segment, the antibacterial properties of Aloe Vera leaf gel extract on cotton, also its effects on the performance parameters of fabric. Softness properties were also imparted on the fabric as it is the inherit property of Aloe Vera leaf gel. Microorganisms; Antimicrobial; Aloe vera; Inhibition, zone; Whiteness index, Textile finishing involves treating a textile material in such a way that the product has the desired functional properties required for its intended use and therefore has greater market value. The desired properties may include the fabrics dimensions and their stability, its weight, drape, appearance, softness, and handle, as well as any required functional properties such as resistance to creasing, flames, water, oil, dirt or bacteria. For the treatment of diseases inhibitory chemicals employed to kill micro-organisms or prevent their growth. The microorganisms are found almost everywhere in the environment and can multiply quickly when basic requirements, such as moisture, nutrients and temperature are met. Most synthetic fibers, due to their high hydrophobicity, are more resistant to attacks by microorganisms than natural fibers. Proteins in keratinous fibers and carbohydrates in cotton can act as nutrients and energy sources under certain conditions. Soil, dust, solutes from saw an ideal antimicrobial treatment of textiles should satisfy several requirements. Firstly, it should be effective against a broad spectrum of bacterial and fungal species, but at the same time exhibit low toxicity to consumers. Secondly, the finishing should be durable to laundering, dry cleaning and hot pressing, a greatest challenge as textile products are subjected to repeated washing during their life. Thirdly, the finishing should not have negative effect on the eat and some textile finishes can also be nutrient sources for microorganisms. For these reasons, it is highly desirable that the growth of microbes on textiles be minimized during their use and storage. Consumers demand for hygienic clothing and active wear has created a substantial market for antimicrobial textile products, one of the fastest growing sectors of the textile market. Sportswear, socks, shoe linings and lingerie accounted for 85% of the total production, quality (e.g., physical strength and handle) or appearance of the textile. Finally, the finishing should preferably be compatible with chemical processes such as dyeing, be cost effective and not produce harmful substances to the environment. One further consideration is that the antimicrobial finishing of textiles should not kill the resident flora of nonpathogenic bacteria on the skin of the wearer. In the last few decades with the increase in new antimicrobial fiber technology, a range of synthetic antimicrobial products such as triclosan, metals and their salts organometallics and their quaternary ammonium compounds have been developed. Although the synthetic antimicrobial agents are very effective against the growth of many microbes and give a durable effect on textiles, but they are cause of the concern due to the associated side effects, action on non-targeted areas and cause water pollution. Hence there is a great demand of antimicrobial agents based on natural ecofriendly agents which not only helps to improve antimicrobial effect but fulfill statutory requirements by regulating agencies. the antimicrobial activity of Aloe Vera extract against pathogenic bacteria. Methanol extract has showed maximum inhibitory activity against E. coli and Candida. A study was done to identify, quantify, and compare the phytochemical contents, antioxidant capacities, and antibacterial activities of Aloe vera lyophilized leaf gel (LGE), The current research aspects of Aloe Vera leaf gel extracts and its application to textile material for both antibacterial cum softness properties has not been reported yet in the previous works so far. In present manuscript, natural plant Aloe Vera extract is applied on pure cotton fabric and its antimicrobial, mechanical and softness properties, Aloe Vera bleeds from the fabric and shows resistance against the bacteria and there is almost no growth surrounding the bacteria. The zone of inhibition for Aloe Vera is less, when compared to the zone of inhibition of other synthetic antibacterial agents. This can be understood from the point that Aloe Vera gel consists of almost 75 components or ingredients and its antibacterial agents may be present in less quantity as compared to other components. It is also clear from this experiment that Aloe Vera, a natural product in its pure form works against bacteria, Aloe Vera shows maximum resistance, its zone of inhibition is higher as compared to the concentrations. Coefficient of friction comprises two types of tests i.e., coefficient of static friction and coefficient of dynamic friction. Coefficient of static and dynamic friction for both pad-dry and coating samples padded with different concentrations and dried at different temperatures. Softness, Aloe Vera exhibits softness and gives soft feel on cotton fabric results in lowering of co-efficient of dynamic friction. Also, increase in centration gives more softness and increase in temperature has reverse effect on it as Aloe Vera gets graded and cotton gets stiff at high temperature. Co-efficient of static and dynamic friction (coating). At high concentrations, the Aloe Vera shows its softness properties as it over comes some of the hardness effects of the binder and thickeners present at the same concentrations in the recipe. Whiteness index for pad-dry samples padded with different concentrations and dried at different temperatures, Bending length of pad-dry and coating with respect to warp and weft wise samples, with different concentrations and dried at different temperatures, Warp wise bending length, decreases as the concentration of Aloe Vera increases. Aloe Vera has softening effect and so its decreases the bending length of the finished fabric. bending length in the weft direction is less as compared to the warp direction because the weft yarns are more relaxed as compared to the warp yarns. Increase in concentration of Aloe Vera decreases the bending length also. The temperature tends no trends for bending length.
