What is behind the brand? Social and environmental sustainability in the upstream phases of the denim value chain

The thesis aims to contribute to the literature of sustainability by undertaking a value chain perspective which asses the environmental and social sustainability practices and approaches adopted by the upstream suppliers within the italian denim value chian, the drivers in the industry and supplier' contribution in trasforming the denim industry in a more sustainable , traceable and transparent one. To achieve this aim, both a quantitative and explorative approach have been followed

Thermal protection properties of aerogel-coated Kevlar woven fabrics

This paper investigated the thermal properties of aerogel-coated Kevlar fabrics under both the ambient temperature and high temperature with laser radiation. It is found that the aerogels combined with a Kevlar fabric contribute to a higher thermal insulation value. Under laser radiation with high temperature, the aerogel content plays a vital role on the surface temperature of the fabrics. At laser radiations with pixel time 330 μs, the surface temperatures of the aerogel coated Kevlar fabrics are 400-440°C lower than that of the uncoated fabric. Results also show that the fabric temperature is directly proportional to pixel time. It can be concluded that the Kevlar fabrics coated with silica aerogel provides better thermal protection under high temperature
