The fabric specimens were treated by 5%, 10%, 15%, 20% and 25% unsaturated polyester resin where styrene monomer used as a solvent and 1% methyl ethyl ketone peroxide (MEKP) was used as initiator. Two bar pressure was applied for complete wetting of the fabric by a Padder and curing was done at 130?C for 10 minutes. The physico-mechanical characteristics of untreated and treated samples were examined and evaluated. It was revealed that moisture content (MC) and water absorbency of the treated specimens were decreased with the increase of resin percentage (%) in the fabrics. MC and water absorbency were maximum decreased up to 50.23% and 60.14% respectively by 25% resin treatment. On the other hand, bending length (BL), flexural rigidity (FR), flexural modulus (FM) and tensile strength (TS) were enhanced with the increase of resin percentage in the fabrics which resulted higher fabric stiffness. The maximum improvement of BL, FR, FM and TS were found to be 6.67%, 56.04%, 10.57% and 18.75% respectively in comparison to untreated sample. Soil degradation tests exhibited that 33.59% TS loss occurred for untreated specimens where only 8.04% loss of TS found for 25% resin treated one. Furthermore, jute based twill, zigzag and diamond fabrics were also treated by 10%, 15%, 20% and 25% resin, then measured their TS and compared with plain fabrics. It was revealed that plain fabrics have superior TS over other fabrics. It was also evident that TS enhanced for all the fabrics after resin treatment and maximum increase found for all the fabrics up to 25% resin treatment.展开更多

Keeping these views in mind, this paper critically examines the political economy of <em>Ippodhu</em> (Tamil Nadu based news website), a hyperlocal news application, in terms of digital labour, audience as participatory commodities and audience as producers, which Alvin Toffler terms as prosumer. Further, this paper explores how social media, analytics, or other analytical tools create value or anti-value for <em>Ippodhu</em>. The qualitative data obtained through in-depth interview reveals that readers/audiences of <em>Ippodhu</em> are commodified in two ways, first they consume the content of the website by spending their time, which will be sold to the advertisers and secondly by creating free content either in the writing stories, uploading photographs or even in the form of comment which will be consumed by other readers/audiences which result in the chain of production of values.展开更多
