Let\u27s sit at the table: Relation between man and table
No full textMiza je predmet, ki se v našem okolju zelo pogosto pojavlja v različnih oblikah in za različne namene, a ji ljudje malokrat namenjajo posebno pozornost, saj jo večina dojema le kot funkcionalni predmet. Večkrat se jo povezuje zgolj s hrano, pijačo in delom. V magistrskem delu z naslovom Usedimo se za mizo: Odnos med človekom in mizo se je avtorica spraševala o samem nastanku mize, pojavitvi na slovenskem ozemlju, o njenem razvoju in tudi uporabi v zgodovini in sedanjosti. Avtoričino zanimanje zajema tako frazeološki pomen mize kot tudi prostorski, materialni, obredni, magični, simbolni in socialni pomen. Spoznala je, da je miza predvsem v današnjem času pogosto dojemana kot nevidna. Vendar pa je posebna vrsta mize, na katero se je avtorica osredotočila – jedilna oziroma družinska miza – v okolju, ki ga je avtorica opazovala, večinoma še vedno osrednji družabni prostor v bivališčih ljudi, kar jo v tej raziskavi tudi prav posebno zanima. Tudi v povezavi z mizo se je v zgodovini odvijalo veliko dogodkov in uveljavilo veliko pravil – tudi šeg in navad –, ki pa so se nekatera ohranila (nekoliko spremenila) tudi do danes. Gledano s funkcionalnega vidika poznamo veliko vrst miz, ki so se spreminjale skozi čas. Ene imajo še vedno isti pomen, druge so ga spremenile in ohranile le ime, spet tretje so novejšega izvora. V delu je avtorica skozi avtorefleksijo opisala tudi svoj odnos in odnos svoje družine do domačih miz, skozi katera je opazovala dogajanje ob njih in jih tudi podrobneje biografsko opisala. Delo tako zajema opazovanje mize kot predmeta v današnjem času ter skozi različne vire in literaturo tudi predmet v preteklosti – njegov razvoj in odnos ljudi do mize v vsakdanjem in prazničnem času v preteklosti in tudi danes.The table is an object that frequently appears in our local environment in many different shapes for different purposes, yet people rarely pay any attention to it because most perceive it only as a functional object. More often than not, it is associated with food, drinks and working. In this master’s thesis titled Let\u27s sit at the table: Relation between man and table, the author explores the origin of the table, its occurrence in the Slovenian territory, evolution as well as its past and present use. The author is interested in the phraseological meaning of the table as well as its spatial, material, ritual, magical, symbolic and social meaning. She realizes that the table, especially nowadays, is often perceived as in visible. However, the specific type of table that the author focuses on – a dining or family table - in the environment that the author observes, has been and continues to be the central social space in people\u27s homes. The latter is also of particular interest in this research. Also, in connection with the table, many events have taken place and many rules have been enforced throughout the history, including customs and habits, some of which have survived (slightly changed) to this day. From a functional point of view, there are many types of tables that have changed over time. Some of them still have the same meaning, some have changed the meaning and kept only the name, while others are of more recent origin. In her work the author, through self-reflection, describes her and her family’s attitude towards home tables. She observes what is happening around them and describes them in biographical detail. The work thus observes the table as an object both nowadays and in the past using various sources and literature - its evolution and people’s attitude towards the table in everyday life and during festivities then and now

Application of ß-cyclodextrin and essential oil of Satureja montana to achieve antimicrobial activity of cotton fabric
No full textVse več znanstvenih raziskav vključuje sredstva z manjšim vplivom na okolje za obdelavo tekstilij, kar je tudi ena od smernic trajnostnega pristopa v tekstilstvu. Mednje sodijo ciklodekstrini, ki so sposobni vključiti v lipofilno notranjost nepolarne spojine, med katere sodijo eterična olja (EO). Zaradi vse večje odpornosti patogenih bakterij na protimikrobna sredstva, so novejše raziskave usmerjene v preučevanje protimikrobne aktivnosti EO. Le-ta so občutljiva na dejavnike iz okolja, zato jih mikrokapsulirajo ali vključujejo v ciklodekstrine. V magistrskem delu je bila preučevana protimikrobna aktivnost bombažne tkanine, impregnirane z ß-ciklodekstrinom (ß-CD) in pršene z EO kraškega šetraja. Sprememba fizikalno-mehanskih lastnosti bombažne tkanine po impregnaciji z ß-CD je bila ovrednotena z meritvami ploščinske mase, zračne prepustnosti, nateznih lastnosti in previsne dolžine. Protimikrobna aktivnost apretiranih vzorcev je bila testirana proti bakterijama Escherichia coli (E. coli) in Staphylococcus aureus (S. aureus). Biorazgradnja je bila spremljana z zakopom vzorcev v zemljo ter vizualno in spektrofotometrično ocenjena z meritvami njihove beline in barve ter z infrardečo spektroskopijo s Fourierjevo transformacijo (FT-IR). Rezultati so pokazali, da sta se vzorcu, apretiranemu z ß-CD povišali ploščinska masa in previsna dolžina, medtem ko so se natezne lastnosti in zračna prepustnost znižale. Prisotnost novih absorpcijskih trakov, značilnih za ß-CD in EO je bila potrjena z analizo FT-IR. Neoprani vzorci, impregnirani z ß-CD pred pršenjem EO in po njem so izkazovali odlično sposobnost redukcije bakterij E. coli in S. aureus. Po desetih pranjih so apretirani vzorci izkazovali zadovoljivo redukcijo le še za E. coli, najboljše protimikrobno delovanje med njimi pa je izkazal vzorec apretiran z ß-CD in 100-odstotnim EO. Biorazgradnja apretiranih vzorcev je potekala počasneje kot neapretiranega. Oprani apretirani vzorci so bili bolj dovzetni za biorazgradnjo od neopranih apretiranih vzorcev.More and more scientific research includes the use of agents with a lower environmental impact, which is also one of the guidelines for a sustainable approach in the textile industry. These include cyclodextrins, which are able to incorporate non-polar compounds, including essential oils (EOs), into their lipophilic interior. Due to the increasing resistance of pathogenic bacteria to antimicrobial agents, recent research has focused on the antimicrobial activity of EOs. These are sensitive to environmental factors and are therefore microencapsulated or incorporated into cyclodextrins. In this master thesis, the antimicrobial activity of cotton fabric impregnated with β-cyclodextrin (β-CD) and then sprayed with Satureja montana EO was investigated. The change in the physical-mechanical properties of the cotton fabric after impregnation with β-CD was evaluated by measuring the mass per surface area, air permeability, tensile properties and bending length. The antimicrobial activity of the treated fabrics was tested against Escherichia coli (E. coli) and Staphylococcus aureus (S. aureus) bacteria. Biodegradation of the samples was monitored after their burial in soil and evaluated visually and spectrophotometrically by measuring their whiteness and colour and by Fourier transform infrared spectroscopy (FT-IR). The results showed an increase in mass per surface area and bending length of the β-CD-treated sample, while tensile properties and air permeability decreased. The presence of new β-CD- and EO-specific absorption bands was confirmed by FT-IR analysis. Unwashed samples impregnated with β-CD before and after spraying with EO showed excellent percentage of reduction of E. coli and S. aureus. After ten washes, finished samples showed a satisfactory reduction only for E. coli, and the best antimicrobial activity was shown by the sample finished with β-CD and 100 % EO. Biodegradation of finished samples was slower compared to the unfinished sample. The finished and washed samples were more susceptible to biodegradation compared to the unwashed finished samples
Printing of pH responsive dye to textile
No full textV diplomskem delu smo preučevali vpliv tiskarske paste, tekstilnega substrata in postopka fiksiranja na pH-odzivnost bombažne in poliamidne tkanine, potiskane z indikatorskim barvilom bromokrezol zeleno s tehniko ploskega filmskega tiska. Barvilo smo nanesli na tkanino v obliki pigmentne tiskarske paste in tiskarske paste za tisk poliamida s kislimi barvili. Uporabili smo dve vrsti fiksiranja tiskov, in sicer toplo-zračno fiksiranje pri 150 °C in času 5 minut ter normalno parjenje pri 100–102 °C in času 30 minut. Vpliv postopka tiskanja na spremembo mehansko-fizikalnih lastnosti tkanine smo testirali v skladu z veljavnimi SIST EN ISO standardi. Barvo vzorcev pred potopitvijo potiskanih vzorcev v pufrske raztopine različnih vrednosti pH in po njej smo spektrofotometrično ovrednotili. Določili smo barvne obstojnosti proti drgnjenju, pranju in na svetlobi.
S postopkom tiskanja smo uspešno oblikoval pH odzivno tekstilijo in tako dokazali, da je postopek tiskanja lahko tudi eden od postopkov aplikacije indikatorskega barvila na tekstilni substrat. Nanos tiskarske paste na vzorce bombažne in poliamidne tkanine je povzročil spremembo mehansko-fizikalnih lastnosti proučevanih tkanin. Hitrost odziva potiskane tkanine na spremembo vrednosti pH je odvisna od surovinske sestave tekstilije in sposobnosti omakanja tekstilije s pufrskimi raztopinami. Barvne obstojnosti potiskanih tkanin na suho in mokro drgnjenje so odlične. Pri preizkušanju barvnih obstojnosti na pranje smo ugotovili, da je potiskana poliamidna tkanina bolj obstojna kot potiskana bombažna tkanina. Potiskani tkanini sta zelo slabo barvno obstojni na svetlobiThis bachelor thesis aims to study the influence of the printing paste, the textile substrate, and the method of fixation on the pH sensitivity of the indicator dye bromocresol green, applied on polyamide and cotton fabric using the flat screen printing technique. The dye was applied in the form of pigment printing paste and printing paste for printing polyamide with acid dyes. Two types of fixations were usedheat fixation at 150°C for 5 minutes and normal steaming at 100 - 102°C, 30 minutes. The influence of the printing process on the change of mechanical and physical properties of the fabric was tested according to the valid SIST EN ISO standards. The colour of samples, before and after their immersion in the buffer solutions with different pH values, was evaluated spectrophotometrically. The colour fastness of the printed textiles to rubbing, washing and light was also investigated.
The pH sensitive textile was successfully developed by printing, which proved that the printing process could be one of the methods used to apply the indicator dye to the textile substrate. The application of printing paste on cotton and polyamide fabric caused a change in the mechanical and physical properties of the studied materials. The speed of response of printed fabrics to the change in pH depends on the types of fibres and the wetting ability of the fabric with buffer solutions. The colour fastness of printed fabrics to dry and wet rubbing is excellent. Printed polyamide fabric is more resistant to washing than printed cotton fabric. Both printed fabrics display poor colour fastness to light
The use of commercial spotting agents in household washing
No full textV diplomskem delu je bil preučevan vpliv tržnih detaširnih sredstev na odstranjevanje različnih umazanij z bombažne, poliestrske in volnene tkanine pri gospodinjskem pranju. V raziskavi so bile uporabljene štiri različne umazanije, ki so v gospodinjstvih pogosto prisotne, in sicer borovnica, kečap, trava in rdeče vino. Uporabljeni sta bili dve tržni znamki detaširnih sredstev, in sicer Texil Detachant (D) in Dr. Beckmann (B). Pranje je bilo izvedeno na več načinov v skladu s standardom SIST EN ISO 105:C06 v napravi GyroWash pri 40 °C. Učinek pranja je bil spektrofotometrično ovrednoten z izračunom barvne razlike med vzorci pred izvedenim pranjem in po njem. Barvna razlika je bila izračunana z uporabo barvnega prostora CIELAB. Rezultati raziskave so pokazali, da je učinkovitost pranja pogojena z načinom pranja, vrsto in sestavo umazanije in surovinsko sestavo tekstilije. Detaširna sredstva B, v kombinaciji s pralnim sredstvom ali brez njega, so izboljšala odstranjevanje preučevanih umazanij s tkanin različnih surovinskih sestav v primerjavi z detaširnimi sredstvi D, kar smo pripisali sestavi detaširnih sredstev.In diploma thesis the influence of commercial spotting agents on removal of different soils from cotton, polyester and wool fabric in household washing was studied. Four different soils were used in the research, namely blueberry, ketchup, grass and red wine, which are very common household soils. Two commercial brands of spotting agents were used: Texil Detachant (D) and Dr. Beckmann (B). The washing of soiled fabrics was performed in accordance to SIST EN ISO 105:C06 standard in GyroWash apparatus at 40 °C. The washing efficiency was evaluated spectrophotometrically by determining of the colour difference between unwashed and washed soiled fabric using CIELAB colour space. The results showed that the washing efficiency was strongly dependent on the washing mode, type and composition of the soil, and the fabric composition. The spotting agents B alone or in combination with washing agent were more efficient in removing the studied soils from fabrics of different composition in comparison with the spotting agents D, which was attributed to the spotting agents’ compositio
The effect of optical brightening agent on the photocolouration of cotton fabric, dyed with microencapsulated photochromic dye
No full textV raziskavi je bil preučevan vpliv dodatka različnih koncentracij optičnega belilnega sredstva (Ultraphor CK) na fotoobarvanje bombažne tkanine, na katero smo po impregnirnem postopku nanesli mikrokapsule fotokromnega barvila (Itofinish UV blue) in vezivo (Itobinder AG). Slednji je bil dodan v kopel za boljše vezanje mikrokapsul na tkanino. Po impregnaciji je sledilo sušenje in kondenzacija vzorcev. Na vzorcih so bile izmerjene ploščinska masa, togost, pretržna sila in raztezek, zračna prepustnost, barvna obstojnost na drgnjenje, barvna obstojnost na gospodinjsko pranje ter barvna obstojnost na svetlobi. Barvo vzorcev pred enominutnim osvetljevanjem z UV-sijalko in po njem smo določili z refleksijskim spektrofotometrom. V primerjavi z nepobarvano tkanino se je pobarvanim tkaninam, ne glede na sestavo barvalne kopeli, povečala ploščinska masa, togost ter pretržna sila in raztezek, medtem ko se je zračna prepustnost zmanjšala. Naraščanje koncentracije optičnega belilnega sredstva v impregnirni kopeli je imelo za posledico manjše vezanje veziva na bombažno tkanino, v katerem so vključene mikrokapsule fotokromnega barvila in s tem znižanje ploščinske mase tkanine ter povečanje zračne prepustnosti tkanine. Pobarvani vzorci so bolj barvno obstojni na mokro kot na suho drgnjenje. Barvna obstojnost pobarvanih vzorcev na pranje se zmanjšuje z naraščajočim številom ciklov pranja. Dodatek veziva v impregnirno kopel omogoči vezanje mikrokapsul fotokromnega barvila na bombažno tkanino. Optično belilno sredstvo zmanjša fotoobarvanje bombažne tkanine, impregnirane z mikrokapsulami fotokromnega barvila in pri daljših časih osvetljevanja (daljših od 12 ur) vzorcev v Xenotest aparatu izboljša barvno obstojnost pobarvanih vzorcev na svetlobi.In the research the impact of different concentrations of optical brightening agent (Ultraphor CK) on the photocolouration of woven cotton fabric, dyed by pad-dry-cure method with the commercial microencapsulated photochromic dye (Itofinish UV blue) and binder (Itobinder AG) was studied. The letter was added to improve binding of microcapsules onto fabric. After padding, followed the drying and curing of the samples. The mass per surface area, stiffness, breaking strength and elongation, air permeability, colour fastness to rubbing, colour fastness to domestic washing and colour fastness to light was measured. The colour of the samples before and after the one-minute illumination with UV light source was spectrophotometrically evaluated by the use of reflectance spectrophotometer. Higher values of mass per unit area, stiffness, breaking strength and elongation were obtained on dyed samples regardless of the dyebath composition in comparison with the undyed cotton fabric. The air permeability was lower on dyed samples. The increase of optical brightening agent concentration in the dyebath resulted in lower embedment of microencapsulated photochromic dye onto cotton fabric and thus a reduction of the mass per unit area and an increase of air permeability of the fabric. The dyed samples have higher colour fastness to wet than to dry rubbing. With the increasing number of washing cycle the colour fastness of dyed samples to domestic washing is decreased. Addition of the binder into the dyebath enable binding of microcapsules of the photochromic dye onto cotton fabric. Optical brightening agent decreases photocolouration of the cotton fabric and therefore increases the colour fastness to light at prolonged exposure (longer than 12 hours) of samples to Xenotest apparatus
The influence of the addition of different pigments and dye on the photocoloration of cotton fabric, printed with microcapsules of photochromic dye
No full textV diplomskem delu je bil preučevan vpliv dodatka klasičnega pigmenta (KP), fosforescenčnega pigmenta (FS) in mikrokapsuliranega termokromnega barvila (TK) na fotoobarvanje bombažne tkanine, potiskane z mikrokapsulami fotokromnega barvila (FC). V raziskavi je bilo pripravljenih sedem tiskarskih past različnih sestav. Tiskarske paste so bile nanesene na 100% bombažno tkanino s tehniko ploskega filmskega tiska. Potiskanim vzorcem so bile izmerjene mehansko-fizikalne lastnosti, barva ter barvne obstojnosti na pranje in svetlobo. Te so bile spektrofotometrično ovrednotene. Potiskanim tkaninam so se povečali debelina, ploščinska masa, togost, pretržna sila in pretržni raztezek, medtem ko se je zračna prepustnost znižala za večkot tretjino v primerjavi z nepotiskano tkanino. Dodatek KP, FS ali TK v tiskarsko pasto, ki je že vsebovala FC, je zmanjšal fotoodzivost tekstilije, med katerimi je imel KP najmanjši vpliv, TK pa največji. Z naraščanjem števila ciklov drgnjenja se je zmanjšalo fotoobarvanje tkanine. Na to je imel najmanjši vpliv dodatek KP, največji pa dodatek TK. Z naraščajočim številom ciklov pranja se je zmanjševala barvna obstojnost potiskanih tkanin na pranje. Dodatek kateregakoli pigmenta ali barvila v tiskarsko pasto, ki že vsebuje FC, poslabša barvno obstojnost tkanin, potiskanih z mikrokapsulami fotokromnega barvila, na pranje. S podaljševanjem časa osvetljevanja vzorcev v aparatu Xenotest se je zmanjšala barvna obstojnost vzorcev na svetlobi. Dodatek KP, FS ali TK v tiskarsko pasto, ki že vsebuje FC, rahlo izboljša barvno obstojnost bombažne tkanine, potiskane s FC na svetlobi.The objective of this diploma thesis was to observe the influence of adding conventional pigment (KP), phosphorescent pigment (FS) and microencapsulated thermochromic dye (TK) on the photocolouration of cotton fabric printed with microencapsulated photochromic dye (FC). Seven printing pastes of different compositions were prepared. The printing pastes were applied to a 100% cotton fabric by a flat screen printing process. The printed samples undergone measurements of mechanical and physical properties, colour and colour fastness to washing and light. The colour of the samples was spectrophotometrically evaluated. Values of thickness, mass per surface area, stiffness, breaking strength and elongation increased on all printed samples, whilst values of air permeability decreased by one third compared to unprinted fabric. The addition of KP, FS or TK into the printing paste, which already contained FC, reduced the photocolouration of the fabric. Moreover, KP had the lowest and TK the highest influence on the fabric photocolouration. With the increase of rubbing cycles, the photocolouration of the printed samples worsened. The biggest influence was observed with the addition of KP and the lowest with the addition of TK. With the increase of laundering cycles the colour fastness of the printed fabric decreased. The addition of any kind of colourant into the printing paste which already containing FC worsened the colour fastness to washing of the fabric printed with microencapsulated photochromic dye. Prolonging the time of illumination of the samples in the Xenotest apparatus decreases the colour fastness of the samples to light. The addition of KP, FS or TK into the printing paste, which already contains FC, slightly improves the colour fastness to light of the cotton fabric printed with FC
Influence of the pretreatment process of cotton fabric on adsorption of methyl orange dye
No full textV diplomskem delu je bila proučevana obarvljivost bombažne tkanine z indikatorskim barvilom metiloranž (MO). Barvanje bombažnih tkanin je bilo izvedeno po izčrpalnem postopku barvanja. Barvanje je bilo opravljeno po dveh postopkih, in sicer brez kationske predobdelave in z dodatkom elektrolita ter s kationsko predobdelavo in brez dodatka elektrolita v barvalno kopel. Obarvane tkanine so bile tudi poobdelane s kationskih sredstvom za izboljšanje mokrih obstojnosti obarvanj. Meritve barve na obarvanih tkaninah in koncentracija barvila v barvalni kopeli ob koncu barvanja so bile spektrofotometrično ovrednotene. pH-odzivnost pobarvanih tkanin je bila prav tako izmerjena spektrofotometrično po potopitvi vzorcev v pufrske raztopine različnih vrednosti pH. Na obarvanih tkaninah so bile preizkušane barvne obstojnosti proti gospodinjskemu in poklicnemu pranju, na umetni svetlobi, na vroče likanje in na drgnjenje. Barvne obstojnosti so bile izvedene in ocenjene v skladu s standardi SIST EN ISO. Rezultati raziskave so pokazali, da kationska predobdelava bombažne tkanine bistveno izboljša izčrpanje barvila MO iz barvalne kopeli na bombažno tkanino. Pobarvana tkanina je barvno odzivna na spremembe pH. Barvna obstojnost pobarvanih tkanin pri pranju je slaba, kljub kationski poobdelavi. Pobarvane tkanine so dobro barvno obstojne na vroče likanje ter suho in mokro drgnjenje ter zelo slabo obstojne na svetlobi.In this diploma thesis, the dyeability of cotton woven fabric with the indicator dye methyl orange (MO) was investigated. Dyeing was performed using the conventional exhaust dyeing process. Dyeing of cotton fabric was carried out by two methods, namely, without cationic pre-treatment and with the addition of electrolyte, and with cationic pre-treatment and without the addition of electrolyte in the dyebath. After dyeing, the dyed fabrics were treated with a cationic agent to improve the wet fastness properties of the fabric. The colour of the dyed fabrics and the concentration of the dye in the dyebath before and after dyeing were evaluated spectrophotometrically. The pH sensitivity of the dyed fabrics was also evaluated spectrophotometrically after the dyed fabrics were immersed in the buffer solutions with different pH values. The dyed fabrics were tested for colour fastness to domestic and commercial laundering, to artificial light, to hot pressing and to rubbing. The tests of colour fastness properties and their evaluation were carried out according to SIST EN ISO standards. The results showed that the cationic pre-treatment of the cotton fabric significantly improves the exhaustion of the dye MO onto the cotton fabric. The dyed fabric is sensitive to pH. The wash fastness of the dyed fabric is poor despite the cationic post-treatment. Dyed fabric has good colour fastness to hot pressing, dry rubbing and wet rubbing but very poor lightfastness
