Bu çalışmada yenilikçi bir yöntem olan ozonlamanın havlu kumaşların ağartılmasında farklı pH (3,5,7,9,11) değerlerindeki etkinliği araştırılmıştır. 5 l/dk ozon gaz akış oranında 15 ve 45 dakika boyunca ozonlama işlemleri yapılmıştır. Ozonlaması yapılan kumaşlara haşıl sökme tayini, beyazlık, hidrofilite, kopma mukavemeti testleri Ağartması kumaşlar sonraki aşamada boyanmıştır. Boyaması renk ölç...

Many textures such as woven fabrics and composites have a regular and repeating texture. This paper presents a new method to capture the texture information using adaptive wavelet bases. Wavelets are compact functions which can be used to generate a multiresolution analysis. Texture constraints are used to adapt the wavelets to better characterize specific textures. An adapted wavelet basis has...

The cellulosic fabrics cotton, rayon, and Tencel® are commonly used in the textile industry (Kroschwitz, 1990). The chemical composition of the fabrics is similar, but they differ in the arrangement of the cellulose polymers in the fabrics (Collier and Tortora, 2001). The basic polymer for all cellulosic fibers consists of repeating glucose units. For the cotton fabric, the cellulosic polymers ...

We report the design and fabrication of a multilayered macroscopic fiber preform and the subsequent drawing and optical characterization of extended lengths of omnidirectional dielectric mirror fibers with submicrometer layer thickness. A pair of glassy materials with substantially different indices of refraction, but with similar thermomechanical properties, was used to construct 21 layers of ...

Woven fabrics prove to be a very convenient fibre reinforcement when prepreg layers have to be draped on to double curvature moulds. The process of draping causes the angle between the warp and weft yarns to vary over the product with this double curvature. As a result, the thermomechanical properties of the fibre reinforced composite material show a corresponding distribution. These thermo-ela...

The purpose of the present research is to study effect textile structure (Coverage factor and type fabrics) on comfort properties (breathability) protection (resistance fluid permeability pores size). Where problem with this in lies lack or scarcity that dealt protection, especially fabric masks, experimental approach was used reach best results . Whereas, woven knitted fabrics were samples. Re...

In this research, fire and radiant heat protection and thermal comfort properties of cotton/nylon-Kermel blended woven fabrics, were utilized to predict the thermal comfort and protection limit of this fabric structure based on Woo and Barker developed model. The results showed that the porosity, the air permeability and the thermal resistance increased with Kermel fiber blend ratio. Conversely...
