A case study of life cycle inventory of cotton curtain

Cradle-to-grave Life Cycle Assessment is used to estimate the potential environmental impacts, from the manufacturing to disposal of any product, process or activity. One of the main difficulties concerned with Life Cycle Inventory (LCI) is the lack of LCI data from developing or emerging countries. Production phase of textile is delocalized to these countries, and this fact has to be taken into account in the frame of a Global Production-Consumption chain. In this study, production location country is Pakistan and consumption takes place in France. Another scope is the textile product selection: cotton curtains were selected as a product to focus on diverse prospective in the production-consumption chain. Lastly, the assessment of environmental impacts consists in tracking all the inputs (including energy, water, etc.…) and the outputs of each step of the production-consumption chain. For example, major atmospheric pollutants such as CO2, SO2, NOx, and other particulates, are quantified

Global Consumption of Flame Retardants and Related Environmental Concerns: A Study on Possible Mechanical Recycling of Flame Retardant Textiles

Flame retardants (FRs) have been around us for decades to increase the chances of survival against fire or flame by limiting its propagation. The FR textiles, irrespective of their atmospheric presence are used in baby clothing, pushchairs, car seats, etc. The overall FR market in Asia, Europe, and the United States in 2007 was around 1.8 million metric tonnes. It is estimated that the worldwide consumption of FRs will reach 2.8 million tonnes in 2018. Unfortunately, a sustainable approach for textile waste, especially in the case of FR textiles, is absent. Incineration and landfill of FR textiles are hindered by various toxic outcomes. To address the need for sustainable methods of discarding FR textiles, the mechanical recycling of cotton curtains was evaluated

Bio-inspired approaches to design bio-luminescent textiles

Luminescent textiles are being increasingly used in apparel and sportswear aswell as in buildings, agriculture and automotives, for safety alert or forillumination or as a design feature[1]. Till now these luminescent textiles havebeen based on technologies such as LED, luminescent particles (rare earthmetals and metal oxides), which are not so eco‐friendly[2].Bio‐inspired strategies can provide efficient methods to achieve eco friendlybioluminescent textiles. Research projects have explored ways which aremainly based on culture of bioluminescent algae[3] or bacteria on textiles.Here we present another approach to achieve bioluminesence using biobasedproducts from various living organisms such as fireflies, fungi, earthwormsthat are found in land and in jelly fishes, shrimps, dinoflagellates, corals inmarine environment [4]. In order to mimic the luminescence effect seen innature, reaction mechanisms in various bioluminescent living organisms arestudied and the components or molecules responsible for luminescence areidentified [5‐10]. Most of the time, these involve enzymatic reactions.However the main challenge is to reproduce the bioluminescent mechanismand to adapt it to new materials which can yield some eco efficient bioinspired luminescent textiles

Measurement of luminescence intensity on textiles using Luminous bacterial biocatalytic system

Nature is the most exquisite thing around us with the existence of living organisms exhibiting different phenomena such as water repel/ency, touch sensitive plant and chameleon skin. Some of these phenomena inspired scientists to explore and design smart fabrics biomimicking the behaviour or pattern in living organisms. Bioluminescence is one such phenomenon where-in different living organisms such as firefly, jelly fish and crustaceans have the ability to impart visible light of specific wavelength, by enzyme catalysed reactions. Existence and study of such light emitting living organisms have been carried out, and harnessing these reactions has already transformed significant areas of medical field and clinical diagnosis, but research work on transforming this into living light is limited. In the present study, luminous bacterial system was investigated to assess and detect the bioluminescence behaviour onto the textile material. In the Luminous bacterial system, in vivo biochemical mecha­nism involves two different enzymes as well as different substrate components. Emission of light due to in vivo luminous bacterial reaction mechanism is seen in visible region. For in vitro reaction mechanism study, physical adsorption technique was used to graft both enzymes on plasma activated PET nonwoven textile and when substrates were introduced manually during the analysis, the biochemical reaction leading to light production occured. A Luminometer equipment was used to determine the light intensity in terms of Relative light units (RLU). The measurement results were obtained for nonwoven plasma treated PET with enzyme and substrate addition at different concentration and RLU value was obtained. The analysis data revealed that light intensity in RLU could be recorded by introducing both the enzymes and substrates on textile material, however intensive research is required in order to observe emitted light through the naked eye. The research study will help to attai
