In this paper, cotton fabrics were washed, bleached and then treated with low-temperature plasma of nitrogen then dyed with direct dyes. Some properties of the samples such as zeta potential, weight loss, crystal intensity, dyeability and washing fastness were investigated. The relative color strength and reflection properties of dyed samples were measured by using reflective spectrophotometry. The morphological changes of cotton samples after nitrogen plasma were studied by scanning electron microscope. Also chemical changes and zeta potential of samples have been investigated by using Fourier Transform Infrared Spectroscopy (FTIR) and zeta sizer respectively. The results show that zeta potential of cotton fabrics influenced by plasma treatment and also dye, plasma treatment cause to improve color strength near 20%.

ÖZET: Polibenzimidazol (PBI) lifleri, yüksek termal ve kimyasal dayanıma sahip uzun zincirli aromatik bir polimer olan PBI polimerinden üretilmektedir. PBI lifleri; yüksek nem geri kazanımı, iyi tuşe ve dökümlülük gibi istenilen özelliklere sahiptir. İlk olarak koruyucu teknik tekstillerde kullanılan bu lifler, günümüzde tekstil ürünlerinin yanı sıra filtrasyon, yakıt hücresi ya da karbon yakalama sistemleri gibi tekstil alanı dışındaki çevre dostu uygulamalarda da sıkça kullanılmaktadır. Bu çalışmada, polibenzimidazol liflerinin üretimine, özellikle-rine ve kullanım alanlarına yer verilmiştir. POLYBENZIMIDAZOLE (PBI) FIBERSABSTRACT: Polybenzimidazole (PBI) fibers are produced from polybenzimidazole polymer which has a high thermal and chemical strength with a long chain aromatic structure. These fibers are first used in protective technical textile products due to their good moisture regain and textile performance properties like good hand and drape. Today, in addition to protective textile market, they are also used in environmental friendly applications such as filtration, fuel cell and carbon capture systems. In this review, production, properties and application areas of polybenzimidazole (PBI) fibers are discussed.

“…It was shown by Rouette and Ohm that wool fabrics can be successfully carbonised by foam application of the sulphuric acid solution [62,63]. They claim that the advantages of their process are the reduced amount of liquor applied, the lower free acid content of the wool and the improved breakdown of the burrs.…”

“…Rouette et al have described the optimum conditions for continuous carbonising with particular reference to the dyeing of carbonised wool with acid dyes, 1:l metal-complex dyes and afterchrome dyes [10,11]. Later Rouette and Kittan discussed carbonising with particular reference to neutralisation and the effect of residual acid content on dye affinity and mechanical properties [12].…”
