69 An Investigation into Properties and Applications of Cupper Coated Polypropylene Fabrics Mojtaba Sarafpour Mojtaba sarafpour@gmail com Date of submission 2014 01 22 Department of Textile Engineering Isfahan University of Technology Isfahan 84156 83111 Iran Degree M Sc Language farsiSupervisor Mostafa Yousefi youssefi@cc iut ac irAbstractCoating of fibers yarns and textiles with metals has become an important issue in textileindustry These fabrics are used in conductive textiles smart textiles water collectionfrom fog and many other fields In this study polypropylene fabrics were coated usingelectroless printing and thermal spray methods Electroless coating was performed bytwo different weight percentages of metal and alsofabrics were printed using threedifferent amount of metal SEM and optical microscopic images were obtained from thesurface and cross section of the fabrics In addition EDXanalysis Mechanical propertiesmeasurements including tensile strength and tear resistance thermal conductivity electrical conductivity washing fastness wettability air permeability and the amount ofwater collected from foggy air were performed EDX analysis revealed existence of41 w w of Cu on the printed sample surface For all of the samples coated ones hadlower tensile strength than that of untreated fabrics In the samples coated with moreamount of the metal tensile strength reduction was lower The results of the tearing testshowed that for the sample which was printed with 12 g kg Cu in the printing paste themaximum force was 153N Also for the sample which was printed with 30 gr kg Cu inthe printing paste the maximum force was 116 75N Therefore 24 reduction in tearingresistance was observed Thermal conductivity of the elecroless coated sample was higherthan that of all other samples Thermal conductivity coefficient of the elecroless coatedsample was six fold higher than that of the untreated sample Electrical conductivity ofthe electroless deposited sample increased 107 times in comparison with the untreatedsample Surface wettability was reduced for all of the coated samples Washing fastness ofthe electroless coated sample was higher than that of the fabrics coated with the othermethods Reduction in air permeability of the electroless coated sample was lower thanthat of fabrics coated using the other methods For the Electroless coated sample theamount of collected water from fog was six fold higher than that of untreated sample Key words coating electroless printing thermal spray Scanning electron microscope water collection from fog
