20.500.12556/RUL-179946 Barvne obstojnosti digitalnih odtisov na belem in črnem bombažnem pletivu Colour fastness of digital prints on white and black cotton knitted fabric V raziskavi so preučevane barvne obstojnosti pigmentov na digitalno potiskanih vzorcih belega in črnega pletiva v sestavi bombaž/elastan. Pri tisku na belo pletivo so bile uporabljene štiri procesne barve, in sicer cian, magenta, rumena in črna, pri tisku na črno pletivo pa le tri procesne barve, in sicer cian, magenta in rumena. Procesne barve so tiskarska črnila, ki so vodne disperzije pigmentov. Vzorci pletiv so bili potiskani z digitalnim kapljičnim tiskalnikom Epson SureColor F2200. Na zraku posušenih in z vakuumsko stiskalnico fiksiranih potiskanih vzorcih so bile barve spektrofotometrično ovrednotene z uporabo barvnega sistema CIELAB. Na potiskanih vzorcih so bili izvedeni testi barvne obstojnosti pri drgnjenju, pranju, vročem likanju, znojenju in na svetlobi v skladu z veljavnimi standardi SIST EN ISO. Barvne obstojnosti so bile vizualno ocenjene s sivo skalo oziroma v primeru barvne obstojnosti na svetlobi z modro volneno skalo. Rezultati raziskave so pokazali, da osnovna barva pletiva vpliva na barvo natisnjenih vzorcev. Barva natisnjenih vzorcev na črnem pletivu je drugačna od barve natisnjenih vzorcev na belem pletivu. Pigmenti na potiskanih vzorcih pletiv so odlično barvno obstojni na svetlobi, zelo dobro do odlično barvno obstojni pri pranju, vročem likanju in proti znoju ter nekoliko manj obstojni pri mokrem drgnjenju v primerjavi s suhim drgnjenjem. Digitalno potiskano bombažno pletivo s pigmenti je primerno za tekstilne izdelke za vsakdanjo rabo. The study investigated the colour fastness of pigments on digitally printed samples of white and black cotton/elastane knitted fabric. Four process colours were used for printing white knitted fabric, namely cyan, magenta, yellow and black, while only three process colours were used for black knitted fabric, namely cyan, magenta and yellow. The knitted samples were printed using the Epson SureColor F2200 digital inkjet printer. Process colours are aqueus dispersions of pigments. The colours of the air-dried vacuum-pressed printed samples were evaluated spectrophotometrically using the CIELAB colour space. The printed samples were tested for colour fastness to rubbing, washing, hot ironing, perspiration and light in accordance with the applicable SIST EN ISO standards. Colour fastness was assessed visually using a grey scale and a blue wool scale was used for light fastness. The results of the study showed that the background colour of the fabric influenced the colour of the printed samples. The colour of black dyed printed knitted fabric deffer influence was more pronounced with black than with white knitted fabric. The colour fastness of samples printed with pigments is excellent to light, very good to excellent to washing, hot ironing and perspiration and slightly less to wet rubbing than to dry rubbing. Digitally printed cotton fabric with pigments is suitable for everyday textile products. Digitalni tisk pigment pletivo bombaž/elastan barvne obstojnosti.
