Abstract

U ovom radu proučavan je utjecaj ekološki povoljnog procesa povezivanja inkluzijskog kompleksa β-ciklodekstrin-crni kim s celuloznim i celuloza/poliesterskim tekstilnim materijalima uz primjenu mikrovalne energije. U tu svrhu provedeno je mehaničko kompleksiranje β-ciklodekstrina i ulja crnog kima uz primjenu visokoenergetskog vibracijskog mikromlina te postupci odležavanja u sušioniku na 80 oC u vremenu od 1 i 24 sata, kao i djelovanje mikrovalne energije u vremenu od 2 i 4 minute uz snagu mikrovalova od 50 %. Pamučni i pamuk/poliesterski uzorci predobrađeni su u 8 % NaOH radi postizanja bolje reaktivnosti pamuka. Pripremljena kupelj za obradu sadržavala je katalizator Na-hipofosfit i maleinsku kiselinu koja je omogućila umrežavanje inkluzijskog kompleksa β-ciklodekstrin-crni kim s celuloznim i celuloza/poliesterskim tekstilnim materijalima. Nakon obrade uzoraka s priređenom kupelji uz djelovanje mikrovalne energije u trajanju od 15 minuta, uzorci su podvrgnuti višestrukim ciklusima pranja kako bi se ustanovilo je li obrada postojana i je li došlo do umrežavanja inkluzijskog kompleksa β-ciklodekstrin-crni kim s tekstilnim supstratom. Tako pripremljeni uzorci podvrgnuti su sljedećim ispitivanjima: primjenom visoko temperaturnog Golden Gate uređaja s ATR sustavom (GG-ATR) nastoje se ustanoviti kemijske promjene u strukturi nastale uslijed djelovanja visokih temperatura, također su se pratile i promjene fizikalno-kemijskih svojstava uz primjenu Fourierove transformacijske infracrvene spektroskopije (FTIR-ATR), promjena mehaničkih svojstava (prekidna čvrstoća i prekidno istezanje), odredile su se promjene spektralnih svojstava vrednovanjem stupnja bjeline i požućenja te su se ispitala i antimikrobna svojstva tako obrađenih tekstilnih supstrata.

Abstract (english)

In this paper, the influence of the ecologically acceptable process of connecting the inclusion complex of β-cyclodextrin-black cumin with cellulose and cellulose/polyester textile materials was studied with the use of microwave energy. For this purpose, the mechanical complexation of β-cyclodextrin and black cumin oil was carried out with the use of high energy vibrational micromill and the process of lying in the dryer at 80 oC in time of 1 and 24 hours, as well as the effect of microwave energy in a time of 2 and 4 minutes with the power of the microwaves of 50 %. Cotton and cotton/polyester samples are pretreated in 8 % NaOH to achieve better cotton reactivity. The prepared bath treatment contained a catalyzer Na-hypophosphite and maleic acid which allowed connecting of the β-cyclodextrin-black cumin inclusion complex with cellulose and cellulose/polyester textile materials. After samples treatment in the prepared bath with 15 minuts activity of microwave energy, samples were exposed to multiple washing cycles to determine if the processing was stabile and if it came to connecting between the inclusion complex of β-cyclodextrin-black cumin and textile substrates. Samples prepared in this way are exposed to the following tests: with use of the high-temperature device Golden Gate with the ATR system (GG-ATR) we attempting to found out chemical changes in the structure caused by the action of high temperatures, using the Fourier transformational infrared spectroscopy (FTIR-ATR) we also followed the changes in physico-chemical characteristics, change of mechanical properties (strength and breaking elongation), the changes in spectral characteristics are established by increasing the degree of whiteness and yellowing, and the antimicrobic characteristics of treated textil substrates are also examined.
