Don) is one of the endemic medicinal plants that is traditionally used to treat a number of diseases. Although the plant has been used to enhance memory, the investigational evidence supporting the nootropic effect was unsubstantial. Hence, the rationale for this study was to assess the potential beneficial effect of F. ammoniacum seed extracts on learning and memory in mice. Methods: The powdered plant samples (aerial parts) were subjected to extraction ad fractionation. Among the extracts, crude and ethyl acetate extracts were screened for major phytochemicals through HPLC analysis. All the extracts were evaluated for the in vitro anticholinesterase (AChE and BChE) and antioxidant potentials. Among the extracts the active fraction was further assessed for improving learning and memory in mice using behavioural tests like Y-maze and novel object recognition test (NORT) using standard protocols. After behavioural tests, all the animals were sacrific...

Enhanced performance effects are achievable using clay mineral in polymeric material. However, special finishing of fibrous material requires studies for establishing any useful effect or for finish development. Fabric finishing using clay may introduce improved flame retardancy. The aim of this paper is to report the results obtained in the flame retardant cotton finishing using local clay minerals. The two types of local clay samples used in this study are described in terms of the flame retardant effects on bleached cotton fabric. It is an indigenous study of clay reserves of country to explore the effects of prepared clay in textile finishing. Effects of indigenous clay samples were collected and the finished cotton was studied in terms of ease of ignition, standard burning length, observed flame propagation, and the residue formation. The finished fabrics were assessed using vertical flame retardant tester.

Alternative or improved material utilization in interior furnishing and structure is perceived important in producing an aircraft. Fibrous material used in an aircraft may enhance the level of safety and the desired effects in producing the structural components. Aircraft accidents and loses to lives and valuable caused by fire are known in aviation history. Flammability in an aircraft as a leading cause or as a subcause may be prevented through an appropriate utilization of flame-retardant (FR) fibrous materials used in aircraft design and manufacturing and in interior furnishing. Improving the prevention of fire hazard through reduced flammability materials was a desired activity for achieving safer air travel. Important FR fibers (FR finished natural fibers and high-performance fibers including synthetic polyamides, carbon, and ceramic fibers), finishes (organophosphorus reagents), and fibrous structural components in aircraft are discussed. FR finishes including brominated FR with reference to recent environmental concerns are described. Standard testing of FR fibrous material based on the Federal Aviation Administration regulations are introduced for any flammability requirements. This study is particularly conducted to appreciate how fibrous materials are useful in improving the flame retardancy and any other performance factor including safety and reduced fuel consumption in an aircraft.

However, an antimicrobial inhibiting the growth or leading the death of microorganism may be harmful to other living species including human being. An increasing consumption of antimicrobial finished fibrous products, and the existing regulations for the registration and control of such products provided strong reasons to appreciate the environment concerns associated with the finished textiles. The published literature in antimicrobial finishing of fibers mainly addressed the development of finish composition, its application, and subsequent evaluation using appropriate methods. Environmental risks that may be associated with the antimicrobial; and its undesired effect during the product service life were the obvious concerns demanding investigations. State of the art development in antimicrobial finishing of textiles emphasized the need for assessing the environment-friendly character of antimicrobial finishes, and the development of antimicrobial effects using natural antimicrobials of plant and animal origin obtainable from the waste materials. Sustainable finish composition and finished fibrous product were apparently found desirable.

Therefore, chemical finishing of cotton fiber, using reduced consumption of water and energy, is obviously important. Apparently, developments in combining the flame-retardant finishing and easy-care finishing would be useful for the textile finishing sector. Any similarity in the type of reagents used in the finish bath and processing conditions, including padding, drying and curing, presents interest as to combining the two separate finishing processes. Flame-retardant and easy-care finishing of cotton fibers requires an appropriate cross-linking agent and catalyst. The finish composition may be applied through the pad-dry-cure processing sequence. Studies have shown the possibility of achieving flame retardancy and crease recovery properties in cotton fiber through combined flame-retardant, and easy-care finishing. Low-formaldehyde based cross-linking agent, or formaldehyde-free cross-linking agent including dimethyloldihydroxyethyleneurea and selected polycarboxylic acids are used. This paper describes some of the important recent development achieved in producing the flame-retardant and crease recovery properties in cotton fabric using combined finish liquor application

Therefore, approaches introducing reduced energy processing of textiles in association with the standard energy management practices would be in obvious demand. Energy management standard is particularly desired for energy-intensive industrial sectors. Textile finishing organizations significantly depends upon the continual energy supply from fiber production to finished fabric. Textile processing areas that heavily consume water and electricity can be significantly improved in terms of reduced energy utilization and minimum energy loses through exercising improved housekeeping and standard management practices. It was perceived that ISO 50001 standard will provide management guideline and approaches to the textile sector organizations leading to an increased efficiency, reduced cost through less energy consumption, and improved energy performance. Any scientific information and data on hot air, heat, steam and processed water recycling available in literature would indeed be beneficial to enhance textile processing and finishing industry in the utilization of energy management policy, performance and efficiency measures, physical structure. The important factors that would be influenced by the energy management standard in textile finishing, ranging over fiber processing, pre-treatments, dyeing, printing, and special effects, are identified for improvement and discussed in this paper.

An important area of the textile sector worthy of serious attention, and where products from the industry are non-existing is tech textile or technical textile, i.e. high performance textiles. This is the area of textile products that are specially designed for high performance applications. Examples of such products include bullet proof jackets, flame retardant textiles, medical textiles (sutures, gloves, bandages, etc.,) clothing for battle and air fields etc. This is the arena of products manufactured to meet the requirements of specific function rather than fashion. A large volume of business is awaited there if the small project investment, in research and development, is initiated.
