Publication Open Access Applications of laser radiation on cotton fabrics dyed gall oak(Quercus infectoria Olivier)(2022-09-01) PARS, ABDULKADİR; PARS A., Karadağ R.In this study, at different ratios mordanted with iron (II) sulfate (FeSO₄.7H₂O) and potassium aluminum sulfate [KAl(SO₄)₂12.H₂O] cotton fabrics were dyed gall oak (Quercus infectoria Olivier). Laser radiation firstly was used on raw cotton fabrics and secondly, cotton fabrics with different ratios of metallic mordanted and dyed with gall oak were irradiated to examine the laser radiation effects on textile color using several combinations of the two main laser parameters namely the number of pulses and energy density at 1064 nm. Colorimetric analysis of the cotton fabrics was measured by CIEL*a*b* spectrophotometer and examined surface alterations. Morphological analysis was performed using optical microscopyPublication Metadata only Investigation of the effects of laser radiation on silk fabrics dyed with kermes insect (Kermes vermilio Planchon)(2023-05-01) PARS, ABDULKADİR; Pars A., Karadağ R.Publication Open Access Mayo Ürünlerinde Kullanılan Tekstil Malzemeleri ve Özellikleri(Bilgin Kültür Sanat Yayınları, 2022-12-01) TURHAN, GÜLDEN; PARS, ABDULKADİR; Temel E. G., Turhan G., Pars A.Kumaşların tasarımına giren teknoloji fark yaratır ve mayo kumaşı buna sadece bir örnektir. Büyük mayo markaları, ürünleri için hangi kumaşların en uygun olduğuna karar vermek için çok zaman harcamakta ve çalışmaktadır. Çoğu zaman, elde etmeye çalışılan amaca bağlı olarak çeşitli liflerden oluşan farklı kumaşlardan değişik stillerde mayolar üretilmiştir. Suda sorunsuz bir şekilde yüzmek istendiğinde, mayonun kumaşı ve bileşimi fark yaratacaktır. Her tekstil malzemesi, kişiye ve uzmanlık düzeyine bağlı olarak suyun içindeyken farklı hissettirecek ve uyum sağlayacaktır. Ek olarak, farklı kumaşların farklı yaşam döngüleri vardır. Bir mayo vücuda daha iyi uyumlu iken, diğeri daha uzun ömürlüdür. Yüzme aktivitesinde en iyi mayoyu bulmak, spordaki veya yarıştaki başarınız için önemlidir. Değişik malzeme karışımları kullanılarak yüzme mayolarının her birine değişik özellikler katmak amaçlanır. Bu çalışmada mayoların içerdiği tekstil malzemeleri ve özellikleri bakımından sürdürülemez mayolar, sürdürülebilir mayo çalışmaları ve günümüz-geleceğin mayoları olmak üzere üç ayrı başlık altında örneklerle incelenmiştir.Publication Metadata only Evaluation of the dyeability of hemp fabric with Anatolian black pine (Pinus nigra subsp. Pallassiana) and Scots pine (Pinus sylvestris L.)(2023-12-01) PARS, ABDULKADİR; Pars A.The development of more sustainable textile dyeing techniques includes a lot of potential in utilizing bio-based plant-derived colorants. Hemp fabric has been dyed with an aqueous extract of pine cones at various dye concentrations to produce a brownish to darker color. Agricultural waste specimens, Anatolian black pine (Pinus nigra subsp. Pallassiana), and Scots pine (Pinus sylvestris L.) cones were used as natural dye sources on a sustainable basis. The dyed hemp fabrics were analyzed by different analytical and technical methods such as CIE L*a*b*, high-pressure liquid chromatography–diode-array detection, and scanning electron microscopy with an energy dispersive X-ray spectrometer. The color characteristics of all the dyed fabrics were measured by a CIE L*a*b* spectrophotometer. The reversed-phase high-pressure liquid chromatography–diode-array detection method with the diode-array detection method was utilized for the identification of the components of dyes present in the dyed fabrics. Scanning electron microscopy with an energy dispersive X-ray spectrometer was used for imaging and elemental analysis of the surfaces of the dyed hemp fabrics. This work has created a novelty direct dyeing method with pine cones without using any mordants and to promote the use of agricultural waste. The fastness values of washing, rubbing, and light were assessed and contrasted. The fastness results were good in general. Washing fastness values were excellent and the same for all fabrics between 4 and 5. Rubbing fastness is also generally good and of the desired grade. The chemical compositions of hemp and pine cones, as well as the formation of dyestuff fiber, were investigated by using Fourier transform infrared analysis.Publication Metadata only PHYSICOCHEMICAL CHARACTERIZATION OF LEATHER OBJECTS OF THE BYZANTINE PERIOD(UNIV AGEAN, DEPT MEDITERRANEAN STUD, 2020) PARS, ABDULKADİR; Massadikova, Guzal; Karadag, Recep; Pars, Abdulkadir; Ozomay, MeralExcavations carried out at the Yenikapi quarter of Istanbul under the Directorate of the Istanbul Archeological Museum between 2004-2013 and have brought the historical importance of the port to light. During the salvage excavations in Yenikapi, hundreds of leather sandals and leather objects from the Byzantine period have been uncovered. The aim of this study is to determine both tanning and coloring materials of eight leather objects belonging to the Byzantine period and physicochemical characterize the leather structure. A complementary analytical approach has been used to characterize leather objects. The ATR-FTIR analysis revealed that the leather objects were tanned with vegetable tannins (gallotanins, condensed tannins and hydrolyzable tannins). By HPLC-DAD analysis, it is known that tannin dye plants were used to color the leather (Quercus infectoria or Quercus ithaburensis). The EDS analysis result showed the possible use of cupric sulfate (CuSO4) for preliminary preparation before tanning leathers during the Byzantine period. In addition, SEM was used for visual assessment of the degree of deterioration of leathers. Based on the EDX analysis, biological deterioration factors and changes in the element ratio have shown that the leather objects deteriorate. In addition, pH, moisture content and CIE* Lab values show that there is a deterioration in the structure of leathers under the sea. The study will sheds light to leather conservation studies.Publication Open Access Physicochemical Properties of Warp Knitted Fabrics Colored with Madder and Gall Oak for Sportswear(2024-07-01) PARS, ABDULKADİR; Karadağ R., Pars A.Polyamide/elastane warp-knitted fabrics were separately dyed with gall oak (Quercus infectoriaOlivier) and madder (Rubia tinctorumL.). Chromatographic and spectroscopic methods were used to analyze dyed warp-knitted fabrics. A reserved phase high-performance liquid chromatography with the diode-array detection (RP-HPLC-DAD) method was utilized to determine the components of dyes present in the dyed fabrics. Scanning electron microscopy-energy X-ray spectroscopy (SEM-EDX) was utilized for morphological analysis. The undyed and dyed warp-knitted fabrics were characterized by FT-IR. The CIEL*a*b* values of the dyed polyamide-elastane warp-knitted fabrics were measured. Further, in physical testing, the pilling and abrasion resistance of raw and dyed fabrics were examined, and the water contact angle values of all fabrics were measured. Pilling test results were evaluated with a grade of 5 for all fabrics as the best score, and the resistance of fabrics to abrasion was very good. The formation of the fiber-metal-dye complex caused the fabric’s contact angle to drop, giving the fabric a hydrophilic character. The colorfastness characteristics of the dyed fabrics to light, rub, wash, and perspiration have been evaluated. The light fastness scores vary from 3 to 5, and they are satisfactory for using natural dyes to color textiles since they are in the good to moderate range. Overall, the dyed samples displayed a score of 5, which is excellent, on the Gray Scale for washing fastness.Publication Open Access Sustainable Bio-Dyeing of Cellulosic-Based Fabrics with Anthocyanins from Black Carrot (Daucus carota L.)(2024-08-01) PARS, ABDULKADİR; Pars A., Karadağ R.In this study, anthocyanin-based black carrot (Daucus carota L.) extract was investigated as a natural textile dye on cellulosebased flax and cotton. Sodium alginate and gall oak (Quercus infectoria Olivier) were used as bio-mordants. The optimal dyeing conditions were determined by varying the amounts of these organic bio-mordants. A CIEL*a*b* spectrophotometer was used to measure the color characteristics of the dyed samples. The RP-HPLC-DAD method was used to identify the dye components in all dyed fabrics. Moreover, the dyed fabrics were evaluated for color fastness to washing, light, and rubbing. The mixture of these bio-mordants gave good color efficiency and acceptable colorfastness test results. Consequently, it appeared that black carrot (Daucus carota L.) can be used to color natural fibers. Applying these natural dye sources and bio-mordants may easily produce various colors.
