Rapid synthesis of silver nanoparticles through economically feasible green chemistry approach is highly desirable. It is well known that on treating the metallic salt solution with some plant extracts, a rapid reduction occur leading to the formation of highly stable metal nanoparticles. In this study we have developed a novel method to synthesize silver nanoparticles by mixing silver salt solution with seed extract of Trigonella foenum (Methi) without using any surfactant or external energy. In this method, physiologically stable, bio-compatible AgNPs were formed. These functionalized AgNPs could be used for targeted drug delievery with enhanced therapeutic efficacy and minimal side effects. With this method rapid synthesis of nanoparticles was observed to occur; i. e. reaction time was 1 to 2 hours as compared to 2 - 4 days required by microorganisms. These nanoparticles were analyzed by various characterization techniques to reveal their morphology, and chemical composition. TEM image of these NPs indicated the formation of spherical, non-uniform, poly-dispersed nanoparticles.

Experiments were conducted using L9 Orthogonal array on button sewing on woven and knitted fabrics to examine factors in securing buttons to fabrics. Button sewing was carried out with parallel formed stitches on four hole buttons and using the Juki computer controlled high speed lock stitch button sewing machine. The factors which govern the quality of button securing to fabrics with sewing threads include the number of stitches, the properties of the sewing thread, the type of fabric, the size of the sewing needle and the properties of the button itself. Pull force was determined using button snap tester as per the standard testing methods to measure the button securing on to the fabric. The button pull tester has two clamps, one being at the lower and the other at the top. The reduction in elongation of the thread is higher with the combination of coarser thread with large size needle sewed through small button holes.

An attempt has been made to use hydrogen peroxide in a combined scouring and bleaching process on mill grey mercerized cotton fabric at a lower temperature in the presence of a bleach activator (potassium persulphate) and an ecofriendly commercial stabilizer. The results on assessment of various quality parameters such as whiteness and tensile strength of the bleached cotton fabric indicate no adverse effect of new process as compared to conventional combined scouring and bleaching process carried out at higher temperature. The new process is found to be successful in terms of savings in energy and time.
