Tisk funkcionalnih barv na tekstil

Rijavec, Brigita (author), Muck, Deja (mentor)

V diplomskem delu je opisan postopek tiska z uporabo prevodnih tiskarskih barv na tekstil. Najprej so bile izdelane enostavne linije ter analizirana tiskarska in tiskovna prehodnost, nato so bile natisnjene RFID antene. Na koncu pa je bilo analizirano delovanje natisnjene RFID antene na dva različna tekstilna materiala, in sicer na poliester in tencel. V teoretičnem delu je predstavljen funkcionalni tisk, predvsem njegov razvoj in prednosti uporabe. Opisan je tudi funkcionalni tisk na tekstil ter sitotisk kot uporabljen način tiska. V praktičnem delu so predstavljeni uporabljeni materiali in metode dela ter postopki izvedbe meritev. Opravljene so bile meritve prevodnosti tiskarske barve, s katero je bila natisnjena RFID antena. Na linijah tekstilnih vzorcev z debelino 0,5 mm tiskarska barva ni prevajala električnega toka, linije višjih debelin (5 mm) pa so na vseh vzorcih uspešno prevajale električni tok. Rezultati analize odpornosti tiskarske barve na drgnjenje so prikazani slikovno. Tiskovni material s slabo odpornostjo na drgnjenje je tencel. Izdelani RFID znački na tekstilnem materialu tencel in poliester sta uspešno delovali. Moč sevanja RFID značke, natisnjene na material tencel, se v primerjavi s papirjem ni bistveno razlikovala, medtem ko je bila moč sevanja RFID značke, natisnjene na poliestrski tkanini, bistveno manjša od drugih vzorcev.

• Title: Printing functional inks on textiles

Abstract

In the diploma thesis is described the process of printing using conductive ink on the textile. First, simple lines were made and printability and runnability was tested and than RFID antennas were printed. Finally, the functioning of the printed RFID antennas was analyzed on two different textile materials, polyester and tencel. In the theoretical part functional printing is presented, in particular, its development and the advantages. Functional printing on textiles and screen printing is also described as the printing method used for printing RFID antennas. The practical part presents materials used for printing, as well as the methods used for performing measurements on samples. The conductivity measurements were made for printing inks used for printing RFID antenna. Measurements showed low or none conductivity for lines with a thickness of 0.5 mm on textile samples, lines of higher thicknesses (5mm) were successfully conducting electrical current. The measurements of the resistance of the printing ink to rubbing are shown graphically for tencel and polyester, the printing material with poorest abrasion resistance is tencel. Printed RFID tags on the textile material tencel and polyester are operating efficiently. Radiated power of RFID tags printed on tencel compared with the RFID tags printed on paper did not differ significantly, while the radiation power of RFID tags printed on polyester is substantially lower than on other samples.
