The purpose of this research was to find the influence of sublimation process on air permeability and water absorption dynamics of knitted and woven polyester-based fabrics.

Three different sublimation designs were prepared and applied (keeping the same sublimation parameters) for eight variants of knitted and four variants of woven polyester-based fabrics. Air permeability and water absorption dynamics during 180s period was measured and compared before and after the sublimation process.

According to the obtained results, high temperature and pressure applied in sublimation process have influence on the porosity and air permeability of knitted fabrics; however, the influence on water absorption dynamics is minimal. Sublimation design dos not have any influence on the mentioned properties.

The obtained results of the sublimation process influence on air permeability and water absorption dynamics of knitted and woven polyester-based fabrics will help to understand how sublimation process can affect comfort properties of textile fabrics.

This contribution is an investigation into the palpable connection of extreme metal music and concepts of death, dying and mortality. Like other dark subcultures, metal has an intense infatuation with the macabre; many of its subcultures seek to uncover meaning through musical exploration into varying dark themes that emerge when thinking about death and what lies beyond the bounds of existence. From the abrasive and animalistic blood lust of death metal to the melancholic textures of black metal and the sonic void evoked in doom metal, extreme metal is a catalyst through which fans of the macabre can explore many perceptions and conceptions of corporeal fragility; the consuming pain of life, of death, and of knowing; and the existential notion of the ungraspable abyss. This chapter explores these varying conceptualisations of death in extreme metal culture, their sonic representations and their cathartic consolation: delving into the psychoanalytic reasoning and embodied sound of death.

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.

To synthesize some new heterocyclic disperse azo dyes and their utilization in textile printing.

To prepare 1‐cayno‐1‐substituted aryl azo‐2‐methyl benzothiazole by the reaction of 2‐aminothiophenol with malononitrile and the end product coupled with different diazonium salts. The prepared dyestuffs are established using element analysis, IR measurements, ¹H‐NMR and Mass spectra. Printing pastes containing the prepared dyestuffs and a thickener were used for printing polyester and/or nylon 6 using either transfer printing or traditional printing.

New selected arylazo cyanomethyl benzothiazole dyes were obtained from the reaction of diazotized aniline derivatives with 2‐cyanomethyl benzothiazole as a coupling component. The suitability of the prepared dyestuffs for either heat transfer printing or traditional printing on polyester and nylon 6 fabrics has been investigated. The prints obtained from dyes containing non polar groups which have sublimation properties possess high colour strength as well as good overall fastness properties if compared to those obtained using dyes containing polar groups.

The new heterocyclic disperse azo dyes were prepared from 2‐cyanomethylbenzothiazole and were utilized in preparing pastes for textile printing to print polyester and nylon 6 fabrics. In addition, the variation in substituents on the synthesized dyes could also be studied.

The method of synthesis of the new dyestuffs provides a simple and practical solution to prepare some new heterocyclic disperse azo dyes with low molecular weight, suitable for sublimation in heat transfer printing methods.

The methods for synthesis of the new heterocyclic disperse azo dyes are simple. These dyestuffs could be used in textile printing of polyester and nylon 6 on an industrial scale.

This chapter theorizes the outrageous consumer response that may follow the communication of political corporate social responsibility (CSR). We consider two recent cases (Starbucks’s offer to hire refugees and Pepsi’s appropriation of protest movements in an ad) and how consumers-citizens reacted when these corporations communicated political issues. By drawing from psychoanalytic concepts, we illustrate how consumers’ outrage, expressed in angry social media comments, and in the creation and sharing of memes, is cathartic of unconscious repressed matter: the realization of their own powerless and the domination of corporations. We further note how these expressions of outrage may be understood to result from defense mechanisms such as denial, displacement, or more complex sublimation that help consumers maintain a position of passive domination by corporations. Like all psychoanalytic applications, our interpretation represents only a plausible metaphor that can explain the “irrational” behavior of consumers. Positivist traditions of CSR theorization may demand further causal studies to confirm the ideas we express. Our study is an original exploration of what underlies consumer responses to political CSR. These cases could inform academics and practitioners working in the business and society arena asking them to re-evaluate whether and how political CSR should be communicated, and the implications of the rapid diffusion of messages in social media that include mocking parody and offensive brand comments.

The purpose of this paper is to investigate the way in which film can introduce jazz to a wider audience.

This study applies the method of subjective personal introspection (SPI) to the area of film and music consumption. The paper reports on insights provided by two researchers through using SPI to investigate their relationships to film and jazz music. In so doing, the paper adopts a Bourdieuian frame in applying a reflexive methodological approach and considering the role of cultural and symbolic capital in influencing these consumption practices.

This paper found that aside from the recognition problem facing jazz, episodes of sublimation may prevent potential audiences from increasing consumption of jazz music.

In common with all SPI studies, the focus of the research is very narrow. While the indepth insight provided here is of use to scholars of arts consumption, further research should explore the prevalence of sublimination in arts communities in order to extend this further.

This study moves our understanding of why consumers may not develop their consumption relationship with jazz music. The findings can be used by jazz professionals in addressing ways in which consumers may overcome their lack of cultural capital and the emphasis placed on this by the wider jazz consumption community.

The paper investigates issues of inclusion and exclusion which should have wider social relevance.

The paper addresses the issue of participation in the arts and should be of value to academics and arts marketing practitioners alike.

The purpose of this paper is to highlight the one bath dyeing method for polyester/wool (PES/Wo) blend fabric with two different semi-synthetic azo dyes developed by chemically modifying the outer skin of Allium cepa.

Chemical modification is the most heartening way to impart improved properties to natural sources. Two different primary amines were coupled with the Allium cepa skin extract by a diazo coupling reaction. Synthesised dyes were characterized for their percentage yield, solubility tests, melting point, particle size analysis as well as FTIR spectroscopy and UV-Visible analysis. One bath dyeing methodology was used for application of synthesized dyes on PES/Wo blend fabric. Dyeing was performed at boil without any additional auxiliary and further percentage dye exhaustion was evaluated.

Dyeing yielded solid shade on PES/Wo blend fabric with satisfactory levelness in dyeing. The efficacy of synthesized dyes for dyeing of PES/Wo fabric was studied by wash, rub, light and sublimation fastness properties, which are in good agreement with commercial requirements. The antimicrobial activity of the synthesized dyes shows excellent activity in dye powder form (AATCC 147 test method) as well as on dyed fabrics (AATCC 100 test method).

Present research work is a first successful attempt to dye PES/Wo blend fabric with semi-synthetic azo dyes in single bath at boil. Such approach facilitates minimum consumption of energy, cost and time.
