Abstract
The issue of waste management is one of the most important issues both today and in the future. Therefore, lots of scholars are endeavoring to add to the economy substances such as paper, glass, and vegetable waste. In this study, the pistachio tree (Pistacia vera L.) branch was used for the first time as a bio waste material as a natural dye source for coloring textile material. For this purpose, waste pistachio branches were collected from Gaziantep province in the south of Türkiye. And then, the dried and grinded branches of pistachio were used for the dyeing of textiles. Dyeing was started at room temperature. The simultaneous-mordanting method was used. The method was performed at a materials-to-liquor ratio of 1:40 for one hour at 100°C. And then it was cooled, washed with soap (1 g/L non-ionic surfactant), and then dried at room temperature. Alum (KAl(SO4)2.12H2O) and iron sulfate (FeSO4.7H2O), which are environmentally friendly, were used as metal salts to increase the efficiency of the dyeing process. The CIE L*a*b* values and K/S values of the dyed fabrics were measured using a spectrophotometer. In addition, washing, perspiration, and rubbing fastness tests were applied to colored fabrics. The results show that fabrics can be colored with sufficient fastness using pistachio tree branches.
Sažetak
Pitanje upravljanja otpadom jedno je od najvažnijih pitanja kako danas tako i u budućnosti. Zbog toga mnogi naučnici nastoje da u ekonomiju dodaju supstance kao što su papir, staklo i otpad od povrća. U ovoj studiji, grana stabla pistacije (Pistacia vera L.) je prvi put korišćena kao biootpadni materijal kao prirodni izvor boje za bojenje tekstilnog materijala. U tu svrhu prikupljene su otpadne grane pistacija iz provincije Gaziantep na jugu Turske. Zatim su osušene i samlevene grane pistacija korišćene za farbanje tekstila. Bojenje je počelo na sobnoj temperaturi. Korišćen je metod simultanog mordiranja. Metoda je izvedena u odnosu materijala prema tečnosti od 1:40 tokom jednog sata na 100°C. Zatim je ohlađena, isprana sapunom (1 g/L nejonskog surfaktanta), a zatim osušena na sobnoj temperaturi. Kao soli metala za povećanje efikasnosti procesa bojenja korišćeni su stipsa (KAl(SO4)2.12H2O) i gvožđe sulfat (FeSO4.7H2O), koji su ekološki prihvatljivi. Vrednosti CIE L*a*b* i K/S vrednosti obojenih tkanina merene su pomoću spektrofotometra. Pored toga, testovi postojanosti pranja, znojenja i trljanja primenjeni su na obojene tkanine. Rezultati pokazuju da se tkanine mogu bojati dovoljno postojano korišćenjem grana drveta pistacija.
