Abstract:Pri posameznih zaščitnih oblačilih ciljamo na zadostno odvajanje površinskega (elektrostatičnega) naboja za kar so se v preteklosti uporabljala predvsem kovinska vlakna. V sodobnem času pa se vedno bolj uveljavlja ogljik, ki ga uporabljamo kot osnovo za izdelavo ogljikovih vlaken, kakor tudi kot surovino, primerno za nanos na tekstilni material, saj je prevodnost ogljika podobna prevodnosti kovin. Za obdelavo tekstilnih materialov, ki temeljijo na sodobnih pristopih, so torej zanimive obdelave z ogljikom. Z njegovo vgraditvijo lahko dosežemo dobro odvajanje električnega naboja z njihove površine, kakor tudi druge lastnosti, kot npr., hidrofobnost, itd. V tem pogledu sta kot tekstilna substrata še posebej zanimiva bombaž in poliester, saj sta osnovna materiala za izdelavo delovnih zaščitnih oblačil. Odvisno od namembnosti se uporabljata, bodisi kot samostojni surovini v oblačilu, bodi v mešanici v različnih razmerjih. Neželen vzporedni učinek vgraditve ogljika je črna oz. kovinska barva vlaken, zato je uporaba ogljika z namenom doseganja antistatično delujočih materialov omejena v glavnem na zelo specifična oblačila. Pričujoče delo temelji na obdelavi substratov iz bombaža, poliestra in mešanici teh surovin z ogljikovimi delci, pridobljenimi z dehidracijo jedilnega sladkorja v kombinaciji z zelenim čajem in železovim (III) hidratom kot katalizatorjem z namenom doseči dobro odvajanje površinskega naboja s površine tekstilnega materiala. Predpostavili smo, da bo le-to izboljšano, v kolikor bo obdelovalni kopeli dodano vezivno sredstvo, ki bi naj povezalo posamezne ogljikove delce med seboj in na ta način izboljšalo funkcionalnost obdelanih substratov v primerjavi z materiali, obdelanimi izključno z ogljikovimi delci. Z namenom preveriti učinkovitost obdelave, so bile v praktičnem delu uporabljene različne metode s katerimi smo želeli dobiti vpogled v videz delcev, kakor tudi v topografijo materialov pred in po obdelavi, za kar je bila uporabljena SEM analiza. Metoda DLS je bila uporabljena z namenom proučiti velikost in stabilnost delcev, prisotnih v posamezni obdelovalni kopeli, merjenje električne prevodnosti/upornosti pa z namenom proučiti sposobnost tekstilnega materiala v smislu samega odvajanja površinskega naboja s površine obdelanega substrata. Vsaka obdelava tekstilnih materialov z ogljikovimi delci se lahko odraža kot izrazita sprememba barvnega tona, zato je bila le-ta spektrofotometrično ovrednotena, prav tako pa tudi nagnjenost obdelanih materialov k gorenju. Rezultati raziskave so pokazali zelo perspektivne rezultate še posebej v primeru, ko je bilo obdelovalni kopeli dodano vezivno sredstvo.

Title:Treatment of textile materials by using carbon, obtained from sugar
Abstract:For specific protective clothing there electrostatic protection is of a big concern which was in the past successfully regulated by combining metal fibers with the different fiber-forming polymers. In modern times, carbon is becoming more and more popular and can be used as the base substrate for the production of carbon fibers as well as for its application onto/into textile material, due to the fact that the conductivity of the carbon is similar to the conductivity of the metal fibers. By treatment of textile materials with the carbon the reduction of the surface electric charge is expected together with the increased hydrophobicity of the treated materials, etc. If considering protective clothing, cotton and polyester, or mixture of these fibers, are usually the main materials. The unpleasant side-effect of introducing carbon onto/into textile material is the possible color change so the use of carbon is limited mainly to the specific clothing e.g. in order to achieve antistatic effect. The presented work is basing on treatment of cotton, polyester and mixtures of these textile substrates by using carbon particles obtained by dehydrated edible sugar subsequently combined with the green tea and the iron (III) hydrate as a catalyst in order to achieve satisfactory level of the electrostatic protection. In addition, it has been assumed that this phenomenon could be improved by adding a binding agent into a treatment bath in order to connect individual carbon particles together thus improving electrostatic protection if compared to the substrate where the binding agent was not part of it. In order to evaluate the effectiveness of the treatment with the carbon particles various methods were used. To get information about particles and to see the topography of the treated materials the SEM analysis was used. To study the size and stability of the particles presented within individual treatment bath the DLS method was chosen as the interesting test method. In addition, the electrical conductivity/resistance, the color difference and flammability were tested as well. Results showed very promising results, especially in the case when the binding agent was part of the treatment bath.
