Sweden has created a thread out of conductive cellulose,which may be used to manufacture electronic textiles. A group of researchersfrom the Chalmers University of Technology in Sweden has been involved in the manufacturing of conductive fibers for electronic textiles for many years. Earlier emphasis was given on silk, but with the emerging discoveries, the focus has now shifted tothe use of cellulose.
By weaving the cellulose threads electricallyto form a fabric with the help of a normalweaving machine, the researchers accomplished to manufacture a thermoelectric fabric that can generate some smaller amount of electricity as soon as it is given heatthrough a person's body temperature on either side. With an increase in temperature of around 37 degrees Celsius, the thread can produceelectricity of around 0.2 Microwatts.
SozanDarabi, a doctorate at the Chalmers University’s Department of Chemistry and Chemical Engineering stated that the cellulose thread can result in attire with preinstalled electronic features, smart functions, and fabricated from an artificial material that is renewable and non-hazardous.
The process of manufacturing the cellulose thread from conductive cellulose has been drafted at Aalto University in Finland. In a succeeding process, the researchers from Chalmers University of technologydevised an approach to make the thread conductive bycoloring it with an electrically sensitive polymeric material. The scientists found that coloring the cellulose thread turned up to be highly conductive, which was never recorded by any earlier approaches. Moreover, the integration of silver nanowires with cellulose fiber has further increased the conductivity of the textile.After certain trials, the team concluded that the conductivity level of the fiber acquiredusing this approach did not fluctuate even after multiple washes.In a broad sense, the textile industry needs to regularly monitor the replacement of its raw material from synthetic to natural resources.The advancement of electrically conductive threads made from cellulose can play an imperative role in different sectors of the market in the future.
