Abstract
Waste management has become a critical issue for sustainable development in manufacturing industries and therefore in textile processing. In the light of this argument an approach for the valorization of a waste come out in yarn spinning processes is presented in this paper. The waste valorized in this context is the dust absorbed from the spinning mill by air conditioners during yarn production. The "air conditioning dust (ACD)" belongs to a cotton yarn spinning line was subjected to a dye extraction process by soxhlet and the solution obtained from the extraction period was used in the coloration of the wool. It was observed that ACD has potential for the coloration of the wool in brown shades. Since the waste was assumed as containing cellulosic structures along with some other dust, the process was called as natural dyeing and different mordants during the dyeings were tested. Additionally, the different dye bath pHs were investigated too. For the evaluation of the results, fastness values and the color analysis of the dyed samples were conducted. It was observed that the ACD has the potential for the coloration of the wool and so can be valorized by this way.
Sažetak
Upravljanje otpadom postalo je kritično pitanje za održivi razvoj u proizvodnim industrijama, a samim tim i u preradi tekstila. U svetlu ovog argumenta u ovom radu je predstavljen pristup za valorizaciju otpada koji nastaje u procesima predenja. Otpad koji se valorizuje u ovom kontekstu je prašina koju klima uređaji apsorbuju iz predionice tokom proizvodnje prediva. Prašina za klimatizaciju (ACD) koja pripada liniji za predenje pamučnog prediva je podvrgnuta procesu ekstrakcije boje sokhletom, a rastvor dobijen tokom perioda ekstrakcije je korišćen za bojenje vune. Primećeno je da ACD ima potencijal za bojenje vune u smeđim nijansama. Pošto se pretpostavljalo da otpad sadrži celulozne strukture zajedno sa nekom drugom prašinom, proces je nazvan prirodnim bojenjem i testirani su različiti jedlači tokom bojenja. Pored toga, ispitani su i različiti pH vrednosti kupatila. Za procenu rezultata sprovedene su vrednosti postojanosti i analiza boje obojenih uzoraka. Primećeno je da ACD ima potencijal za obojenje vune i da se može valorizovati na ovaj način.
