This study investigates the detoxification properties of guanidinylated chitosan against chemical warfare agents and its application to the preparation of military protective clothing. Guanidinylated chitosan was synthesized by chitosan guanidinylation with cyanamide. The detoxification properties of the guanidinylated chitosan were then evaluated using a chemical warfare agent simulant, called diisopropylfluorophosphate (DFP). Cotton fabric was treated with 1 wt.% of guanidinylated chitosan in acetic acid and water solution using the simple and conventional textile treatment method of pad–dry–cure. The detoxification properties of the guanidinylated chitosan-treated cotton fabric were evaluated to investigate the application of guanidinylated chitosan to the preparation of military protective clothing. Subsequently, 71.3% of DFP was hydrolyzed to non-hazardous diisopropylhydrogenphosphate (DHP) in 2 h because of the base organocatalytic activity of 0.02 g guanidinylated chitosan itself. Moreover, 60.1% of DFP was hydrolyzed by the catalytic activity of the guanidinylated chitosan-treated cotton fabric, which contained only 0.0002 g of guanidinylated chitosan. This result shows that the guanidinylated chitosan itself has detoxification properties for hydrolyzing DFP to DHP, and its detoxification properties can be more efficient when applied to cotton fabric because it showed 84.3% of the detoxification properties with only 1 wt.% of guanidinylated chitosan. For the first time, this study shows that guanidinylated chitosan has considerable detoxification properties and can be used as an agent to prepare protective clothing.

"More than 10 years ago, Tim Gunn and Project Runway introduced millions of viewers to New York's ultimate fabric mecca, Mood Fabrics. Now, the experts behind this fabric power- house bring their fabric and fashion know-how--plus their behind-the-scenes stories--to the sewing public. The Mood Guide to Fabric and Fashion is the ultimate guide for home-sewers, fashion students, aspiring designers, and Project Runway fans who want to learn everything they need to know to choose and use quality fabric. Drawing upon the expertise of the Mood staff, the book teaches readers the fundamentals--from where fabric is produced to the ins and outs of its construction--and features a fabric-by-fabric guide to cottons and other plant fibers, wools, silks, knits, and other specialty fabrics." -- Publisher's description

AbstractThe textile industry is ambitiously parading towards circularity and curtailing its dependency on fossil fuels hence the instigated research that adheres to Sustainable Developmental Goals (SDGs) and benefits the environment and human health alike. The current research experimented with innovative sources of plant-based biomaterials namely dandelion leaves, bilberry leaves, nettle leaves, and violet herb for application on cotton fabric as biomordants and colourants. The AAS analysis of mild 6% herbal solution revealed ferrous content of 6.78 mg/l in violet herb and 5.03 mg/l of the copper content in dandelion leaves applicable on cotton fabrics as biomordants thereby preventing the depletion of copper and ferrous elements mineral ores. A fair lightfastness rating and good to very good wash and rub fastness test results were obtained individually. The maximum K/S value of 13.95 was gained on cotton fabrics treated with a mild herbal infusion of bilberry leaves and coloured with violet herbs. The ATR-FTIR peak analysis noted strong = C-H bend of alkenes, strong C = O stretch of α and β unsaturated esters, and strong C-O stretch of carboxylic acids functional groups in raw herbs and its treated cotton fabrics. The dissolved oxygen (DO), oxidation–reduction potential (ORP), and potential of Hydrogen (pH) values were found in the acceptable range for all the spent solutions left after colouration of cotton fabrics with violet herbs hence sustainable. The data set obtained was statistically validated with ANOVA one-way test. Life cycle analysis and clinical investigation on potential therapeutic benefits of herbal fabrics to the wearer are suggested for future research and development.

Cotton is one of the most important and ancient crop of the world. It plays a very signification role in the economic,political and social affairs of the world. In India, cotton is cultivated as an important cash crop and used as fabric since time immemorial. Ancient texts of India like Rig Veda, Dharmashastra etc. mention the use of cotton. There are evidences to indicate that India had been the centre of important textile industry as early as 1500 BC. At present, Indian textile industry with more than 1062 textile mills constitutes one of the largest contributor to the economy in terms of annual output and labour employed, both direct and indirect. A poverty line is the income required for a minimum consumption level of food,clothing, shelter, transport, health care, and other necessary items. In 1979, the Task Force on Projections of Minimum Needs and Effective Consumption Demand defined the poverty line as the per capita consumption expenditure level at which the average daily calorie requirement were met on the basis of the all-India consumption basket using 1973–1974 data from the National Sample Survey (NSS) 28th round. The task forceused the age/sex/activity-specific calorie allowances recommended by the Nutrition Expert Group to estimate the average dailyper capita requirement for rural and urban areas (2,400 kilocalories in rural areas and 2,100 kilocalories in urban areas), usingtheir respective population structures as projected for 1982–1983. Thus, to the extent the data permitted, the age, sex, andoccupational differentials in the population's daily calorie requirement were captured in the average norms.

This is an Australian army nurse uniform. It is made from an olive green cotton fabric and was produced by A.G.C.F. Victoria. The uniform has two tags sewn onto the inside of the dress. A business card from Aussie Digger militaria along with some dark green ribbon was found in the left pocket of the dress (unphotographed). ; https://digitalcommons.molloy.edu/nur_hagan/1468/thumbnail.jpg
