Abstract:Področja krožnega gospodarstva, kot so odpadki, raba naravnih virov in energije, zajemajo tudi tekstil in tekstilno industrijo - strategija o trajnostnem tekstilu in rabi naravnih barvil. Tekstilni materiali (naravni in sintetični) so, glede na potrebe in želje kupcev, obarvani ali tiskani. Skoraj vsa sintetična barvila, ki se množično uporabljajo za te namene, sintetizirajo iz fosilnih derivatov z nevernimi kemijskimi postopki, ki imajo negativen vpliv na okolje. Zato je vse večja zavest potrošnikov o okolju prijaznih izdelkih povzročila porast izdelave tekstilij iz naravnih vlaken, barvanih z okolju prijaznimi naravnimi barvili. Cilj magistrske naloge je bil raziskati različne možnosti ekstrakcije naravnega barvila iz ostankov murvinih vej po spomladanskem obrezovanju, ter iz pridobljenih barvil pripraviti okolju prijaznejše tiskarske barvne gošče. Za pridobivanje naravnega barvila iz vej murv smo uporabili ekstrakcijski postopek v Soxletovem ekstraktorju z dvema različnima topiloma, destilirano vodo in etanolom in njunima različnima razmerjema. Izolirane ekstrakte smo okarakterizirali z UV/VIS spektroskopijo, antioksidativnostjo ter z določitvijo fenolnih skupin. Najustreznejši izoliran ekstrakt smo uporabili v postopku direktnega tiska, pri katerem je bila tiskarska barvna gošča pripravljena iz okolju prijazih kemikalij. Seveda nas je zanimala tudi kakovost in obstojnost oblikovanega tiska. Rezultati kažejo, da je za tisk najprimernejša TBG 3 (tiskarska barvna gošča 3, katera je vsebovala monijev železov(II) sulfat) na bombažni tkanini. Zelo dobre lastnosti ima tudi TBG 2 (tiskarska barvna gošča 2, katera je vsebovala kalijev galun).

Title:Study on the Use of Dyes from Mulberry Branch Waste In Textile Printing
Abstract:Circular economy areas, such as waste, natural resources and energy use, also include textiles and the textile industry - a strategy for sustainable textiles and the use of natural dyes. Textiles (natural and synthetic) have been and continue to be dyed and printed according to customer needs and preferences. Almost all synthetic dyes that are mass used for these purposes synthesized from fossil fuels using hazardous chemical processes and threaten the environment. Therefore, the growing consumer of environmentally friendly products has increased the production of textiles made from natural fibers dyed with environmentally friendly natural dyes. The aim of the master thesis was to investigate different ways of extracting natural dyes from mulberry residues after spring pruning and to prepare more environmentally friendly printing dye slurries from the extracted dyes. To extract the natural dye from mulberry branches, we used an extraction procedure in a Soxhlet extractor with two different solvents, distilled water and ethanol and their different ratios. The isolated extracts were used in the direct printing process, in which the ink slurry was prepared from non-aggressive chemicals. Naturally, we were also interested in the quality and durability of the print produced. The results show that the most suitable for printing is TBG 3 (printing paste 3, which contained ammonium iron(II)sulfate) on cotton fabric. TBG 2 (printing paste contained potassium alum) also has very good properties.
