Weight reduction increased the amount of deposited polypyrrole (PPy) on the polyester (PET) fiber surface, leading to a considerable decrease in electrical resistance and improved heat generation capacity for the PPy coated PET fabrics. Application of DC voltages to an insulated roll of PPy-coated fabric increased the temperature to about 90 oC. This showed the suitability of these fabrics for ...

1. Abstract Natural fibers are being increasingly used to substitute artificial glass and carbon fibers in polymer composites. It is important to know how the mechanical properties of these natural fiber composites compare with those of the traditional glass and carbon fiber composites. Glass and carbon fiber composites are currently being used in many applications that may not require such hig...

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...

Agenda 2020 has identified the need to improve the quality of recovered fiber. This project addresses this challenge with the use oxidative enzymes, such as laccase and soybean peroxidase/hydrogen peroxide, that increase the fiber charge of recycled fibers. By increasing the number of surface carboxylic acid groups on recycle fiber, this treatment will improve paper strength. In addition, oxida...
