Investigations of dye adsorpThe effects of tannic acid and Rhodamine B on the zeta potention on the materials and the electrical and thermodynamic tials and surface free energy components of polyester fabric (Daproperties of the fiber/solution interface are fundamental for cron 54, Style 777) were studied. Knowledge of these parameters understanding the dyeing mec...

Abstract This study investigates the influence of steel and polyester fibers on mechanical durability properties steel–polymer hybrid fiber reinforced concrete (HyFRC) toughness under indirect tensile loading conditions. Steel Polyester are used as a single type (FRC) in combination an M45 grade composite with addition fly ash silica fume supplementary cementitious material. exhibited 10% impro...

Structural macromolecular parameters of normal and treated (acid & alkali) polyester fibers have been investigated using Small Angle X-ray Scattering (SAXS) technique. Average diameters were calculated from Scanning electron microscope (SEM) micrographs and mechanical parameters were estimated using Instron. Further, crystallinity parameters of the same fibers have been determined using X-ray d...

The paper presents review of research work experimental investigation on polypropylene fibre reinforced concrete and concrete with artificial sand. Use of fiber reinforce polymer in civil engineering increase rapidly. Various type of fiber is used such as glass, carbon, steel, asbestos, polyester and polypropylene. The various experimental investigations for determination of properties of polyp...

Environmental protection has become an increasing concern, which makes recycling and reclaiming highly important. In addition to governmental campaigns and promotion, enterprises should examine each perspective thoroughly in order to prevent excessive resource consumption. In this study, recycled materials, including recycled far-infrared polyester (FPET) fiber, three-dimensional crimped hollow...

World textile fiber demand was 89.8 million tons in 2015 and is expected to grow to 93.7 million tons in 2016. Global demand for textile fibers is driven by population growth and by economic activity resulting in increasing wealth, particularly in emerging economies. While this overall trend is consistent across most major fibers, there are substantial disparities in the demand patterns of natu...

A fibrous material is characterized by its fineness, flexibility and high length/fineness ratio it used to reduce noise in indoor rooms due their porous structure. The aim of this work focused on investigating the structure two different fibers (acrylic polyester) from analysis macrostructural parameters, such as length cross-section (solid or hollow). Furthermore, degree influence these parame...

Kinetic modeling of enzymolysis of pulp fiber waste pretreated by a wet oxidation process was studied. First, a wet oxidation pretreatment of fiber waste was carried out. It was found that hemicellulose were removed efficiently, yielding material with a pentosan content of 4% (based on the o.d. biomass). A statistical kinetic model was developed based on the experimental results of the enzymati...
