Conductive yarns and coatings are essential for a broad variety of smart textile applications, such as sensors, data transmission lines, or heated fabrics

Strong influence of textile substrates – The washing resistance of different graphite–polyurethane coatings with graphite contents between 25% and 33% on cotton, linen, viscose, and polyester woven fabrics was compared, using two different graphite particle sizes on diverse textile substrates, in a recent study. It was found that not only the graphite particle dimensions and graphite concentration strongly influence the longevity of the coatings, but also the textile substrates which were coated with the conductive mass. This means that conductive coatings cannot be optimised without knowledge of the planned application.

Progress of graphite based conductive textile coatings -Conductive yarns and coatings are necessary for a broad variety of smart textile applications, such as sensors, data transmission lines, or heated fabrics. The main problems of such conductive textile elements are abrasion and washing resistance. Since different findings with respect to these properties are reported in the literature for similar coatings, the required optimisation is hindered.

The washing resistance of different graphite–polyurethane coatings was tested in a new study. Lately, scientists compared the washing resistance of different graphite–polyurethane coatings on cotton, linen, viscose, and polyester woven fabrics.
