In this study, electromagnetic shielding properties of needle-punched nonwoven fabrics were investigated. The paper evaluates and compares the electromagnetic shielding of needle-punched nonwoven fabrics produced from stainless steel/polyester and normal polyester fibers. Stainless steel/polyester fiber and normal polyester fiber were blended at sp...

Polypyrrole (PPy) coated cotton yarns were prepared by the vapour phase polymerisation technique at various initiator concentrations. Iron (III) chloride (FeCl3) was used as the initiator at four different concentrations (0.2, 0.4, 0.6&0.8 mol/l) respectively. In this work, the effects of initiator concentration on the tensile, electrical and morph...

Polypyrrole was deposited on polyester yarns by vapour phase polymerization technique. Ferric chloride was used as an initiator. In order to determine the effect of the initiator concentration on polymerization process, four different initiator concentrations (0.2, 0.4, 0.6 and 0.8 mol/l) were used. The effect of the initiator in terms of tensile p...

Polymer-based composite structures have advantages over other materials. The most important advantage is the higher mechanical properties obtained from the composites when supported by fiber reinforcement. The mechanical and thermal properties of fiber-reinforced composite structures are affected by the amount of fibers in the structures, orientati...

In this study, composite structures were produced using HDPE polymer with silk and cotton waste as reinforcement fibers in different ratios. Cotton and silk wastes were mixed in the ratios of HDPE/silk or cotton waste 100%/0%, 97%/3%, and 94%/6%. This mixture was prepared with double-screwed extruder. The tests were carried out in terms of tensile...

In this research the effects of the yarn balloon angle on yarn hairiness and other yarn properties was investigated. The yarn balloon was changed by use of five different weights of C type travellers. The yarn counts chosen were 15 tex, 20 tex and 30 tex. Three spindle speeds were used: 9,000 r.p.m., 10,000 r.p.m. and 11,000 r.p.m. Yarn hairiness,...

The field of ultrasonic is still making strides towards perfection, but already many applications of ultrasonic energy have been found in science and technology. There is also a field called sonochemistry where ultrasonic energy is used to create some chemical and mechanical effects on matter immersed or solved in liquids. It was presumed that ultr...

Although ultrasonic energy is widely used cleaning and degreasing of parts and assemblies in automotive and other industries, the use of ultrasonic energy in an industrial scale for textile washing is very new. This is due to the complexity of controlling the combination of chemical and mechanical effects, whereas with degreasing of machine parts o...
