| Abstract | The effect of ammonium sulfate (NH$_{4}$)$_{2}$SO$_{4}$ on the flammability of 100% cotton woven fabric (plain 144 g m$^{−2}$, the number of yarns 21 per 10 mm) has been of interest in this study. The laundered bone-dried, massed fabrics were impregnated with suitable concentration of aqueous ammonium sulfate solutions by means of squeeze rolls, drying and conditioning. Afterwards the specimen’s resistance to burning has been determined. The optimum add-on value of ammonium sulfate to impart flame-retardancy to cotton fabric was in a range about 10.55–13.62 g anhydrous salt per 100 g fabric.Thermogravimetry (TG/DTG) of the pure cotton and the treated one with the above-mentioned sulfate as well as for pure salt were also accomplished and their TG curves were compared and commented to detect the combustion’s pathway of the supported substrate. TG data confirm major mass loss in treated cotton. It occurred well below at a punctual duration of the thermal degradation zone of the polymer. So fewer flammable volatiles and more char could be produced during combustion. The results obtained are in compliance with gas dilution theory and also chemical action theory. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.
