This paper aims to develop a novel protocol for the synthesis of disperse dyes derived by a triple cascade reaction with lawsone in presence of Zn acetate as a catalyst. The developed novel scaffolds have efficient dyeing properties on nylon and polyester fibers.

This report demonstrates an effectual triple cascade protocol for the synthesis of novel disperse dyes derived from various polynuclear carbaldehyde, urea and lawsone. The Zn acetate was found to be an effective catalyst for this reaction. Their dyeing performance has been studied on nylon and polyester fabrics. The wash fastness, sublimation fastness, color assessment, determination of percentage exhaustion and fixation properties were applied to both the dyed fabrics.

The obtained results indicate that the Zn acetate is an efficient catalyst for the developed triple cascade protocol. The prepared novel disperse dye greatly impacted their dyeing properties on nylon and polyester fibers. They have shown brilliant shades, higher affinity, adsorption capacity, superior tinctorial strength than the lawsone. The percentage exhaustion value, fixation value, color strength (K/s) value, washing and sublimation fastness properties have been found very well in all dyed nylon samples compared to polyester samples. These results discloses that these disperses dyes are very useful to the growing importance of nylon and polyester fibers.

The present protocol synthesizes the racemic mixture of the prepared molecules.

Developed protocol can be used for various other triple cascade processes. Also these molecules can be used for dyeing of other fabrics.

With the help of commercialization of prepared molecules, it may provide the better alternative of the current disperse dyes. This may affect the various segments of society.

This report represents a novel protocol for the synthesis of modified novel disperse dyes with an efficient dyeing properties on nylon and polyester fibers.

This chapter explores the interaction between different kinds of knowledge and representations in the making of the ‘fleshed’ female reproductive body in an Indian city. In particular, it analyzes how women perceive contraception and how the reproductive governance helped to produce the female sterilization as the most widely used contraceptive method in India. The study is based on the case of the city of Bhuj, in the state of Gujarat (India), where three anthropological fieldworks (15 months) were conducted. Modern contraceptive methods are based on a biomedical representation of the body, drawn from Western categories of knowledge and experience, whereas women live the ‘fleshed’ reproductive body through local categories of substance and fluids. How is this knowledge mobilized and affected in relation to reproductive technologies and the government of reproduction? This question is addressed through the analysis of women's embodied experiences of contraception. The narratives collected show a resistance to biomedicine, considered to be a model that alters the female body and its reproductive capacity. Nevertheless, even when sterilization was considered to be a deliberate act of tampering with the functioning of their bodies, women displayed a pragmatic agency in choosing this method. The experiences of respondents reflected complex negotiations between bodily suffering, socio-economic structures and the microphysics of power surrounding them, rather than a unilateral submission to medical authority and reproductive governance.
