Comparative evaluation of cotton and polyester woven fabrics finished with nanoparticles water repellent materials

Akademik ve endüstriyel olarak, nanometre ölçeğinde üretim miktarında bir artış görülmektedir. Ayrıca günlük hayatta ve malzeme teknolojilerindeki ileri uygulamaların kullanım taleplerinde de büyüme söz konusu olmaktadır. Moleküler seviyedeki nano teknoloji, yüksek kopma mukavemeti, sağlamlık, yumuşak tutum, su iticilik, güç tutuşurluk, anti mikrobiyal özellikler gibi istenen tekstil karakteristiklerin geliştirilmesinde kullanılabilmektedir. Nano teknolojideki son gelişmeler, tekstil endüstrisinde büyük fırsatlar yaratmaktadır. Tekstil materyallerine hidrofobik karakter kazandırmak için yapılan işlemler birçok çalışmanın konusunu oluşturmaktadır. Diğer taraftan, nano partiküllü su itici materyallerle işlem görmüş kumaşların performanslarının değerlendirilmesi yeni bir konu olarak görülmektedir. Bu çalışmanın amacı, su itici nano teknolojik bitim işlemlerinin araştırılması ve değerlendirilmesidir. Bu araştırmada ticari olarak kullanılan nano partiküllü su itici materyaller ile konvansiyonel su itici materyaller karşılaştırılmaktadır. Pamuk, polyester ve pamuk/polyester karışım kumaşlar kullanılmıştır. Numuneler iki farklı nano partiküllü kimyasal ile emdirildikten sonra termofiksaj işlemi yapılmıştır. Her tipte su iticilik maddesi ile işlem görmüş kumaşların yüzey özellikleri incelenmiştir. Kumaşların performanslarını ölçmek için sprey test cihazı ve hidrostatik test cihazı kullanılmış, ayrıca deneysel sonuçlar istatistiksel olarak değerlendirilmiştir. Deney sonuçları, nano partiküllü su iticilik maddeleriyle yapılan bitim işlemlerinin kumaşların su iticilik özelliklerini arttırdığını göstermektedir.There is an increasing amount of academic and industrial activity to produce multifunctional nanometre -scale containers and a growing demand for their use in sophisticated applications in the life and materials sciences. Nanotechnology at the molecular level can also be used to develop desired textile characteristics, such as high tensile strength, durability, soft hand, water repellent, fire retardant, antimicrobial properties and more alike. Recent advances in Nanotechnology have, indeed, created enormous opportunities and challenges for the textile industry, including the cotton industry. Treatment of textile materials in order to attain hydrophobic character has been the subject of many researches. On the other hand, finishing of fabrics with. Nano particles Water Repellent Materials and evaluation of quality performances of the resultant fabrics appear to be a receptive issue. The focus of this paper is, therefore, to investigate and evaluate applications of Nanotechnology finishing concerning water repellence

The Effect of Different Connections in Double Layered Woven Fabrics on Comfort Properties

WOS: 000300962200019With the increasing demand of fabrics for special usage areas, more complex woven structures are designed and from the structural point of view, especially the parameters which affect the comfort properties become more important. This paper reports the effect of structural parameters of double layered woven fabrics, such as number of interlacing picks, period of interlacing and number of weft skips on the basic comfort properties of the fabrics (thickness, air permeability and wicking properties) produced according to Taguchi orthogonal array design. The investigated parameters were determined before and after finishing treatment. According to the results, it is found that period of interlacing has an important effect on the thickness and air permeability of both untreated and treated fabrics whereas in terms of drying coefficient, the effect of the investigated parameters is not statistically important

Investigation of the usage possibility of copper cyclohexane monocarboxylate (copper naphthenate) as a textile dye

In this study, usage possibility of naphthenates, which is known as saturated hydrocarbons present in the chemical composition of grease obtained from the handling of petrol, as a dye in textile industry was investigated. For this aim, firstly the naphthenate copper complex (a dye containing metal) with blue color is obtained from the reaction of naphthenate acid and copper salt obtained from the side fraction of petrol. Chemical composition of this compound was analyzed by using spectrophotometric methods (IR, NMR and ESR). Furthermore, optimum conditions for solubility of synthesized dye were determined in the presence and absence of ultrasound. Then, dyeability of various fibers (cotton, wool, polyamide, polyester, polyacrylnitrile) with synthesized dye was determined. Finally, tests were performed in order to determine whether the dye has carcinogenic and/or allergy effect. According to the results, it was observed that there is no danger in this direction. According to the experimental results, it was determined that copper naphthenate compound can be used in dyeing of wool fibers
