The main objective of this research is to investigate the electrochemical characteristics Ni–Cu-plated polyester when MnO2 deposited on it and serves as a flexible electrode. For purpose, electrode fabrics prepared in way were with over different immersion times. conductive that was underwent an aqueous solution KMnO4 (0.1 M) for durations 5, 10, 30 min. electrical resistance samples measured using two-point probe technique. Additionally, properties deposition examined three-electrode cell...

A natural dye extracted from eucalyptus leaves was applied to a silk fabric using two padding techniques, namely the pad‐batch and pad‐dry under different conditions. It observed that with an increase in concentration, ultraviolet (UV) protection factor (UPF) values ranged between good excellent for fabric. In addition, darker colour, such as provided by FeSO4 mordant, gave better because of higher UV absorption. dyed solution containing leaf extract showed shade pale yellowish‐brown. The...

Functionalities of 3D printing filaments have gained much attention owing to their properties for various applications in the last few years. Innovative biocomposite based on polylactic acid (PLA) composited with ZnO nanoflowers at varying contents were successfully fabricated via a single-screw extrusion technique. The effects nanoflower chemical, thermal, mechanical, and antibacterial investigated using Fourier transform infrared spectroscopy (FTIR), differential scanning calorimetry...

The objective of this research was to study the effects using extraction procedures on raw water hyacinth fiber produce an improved quality fiber, applying different methods extraction. mechanical method for first employed a semi-automatic machine grate outer stems hyacinth. Following this, several approaches were used, including mechanical, chemical, natural alkali, retting, and boiling procedures. aim obtain rapid efficient outcome, which is ideal production in industrial use. results...

This research focuses on the mechanical properties of polypropylene (PP) blended with recycled PP (rPP) at various concentrations. The rPP can be added up to 40 wt% into matrix without significantly affecting properties. MFI increased increasing content. Modulus and tensile strength slightly decreased content, while elongation break 30.68% a increase in is probably caused by interfacial adhesion during blending process. electrical conductivity materials was improved adding carbon black...

The idea of generating high-value practical materials, such as activated carbons, from agricultural wastes a raw material has been quite important trend recently due to its positive contributions the environment and resource savings biomass. In this paper, carbons prepared durian husk waste by KOH chemical activation method are studied. We focus on effects stages activating temperature their properties. optimum conditions for were KOH/char ratio 1:2 at first second process temperatures 400...

This research focuses on silk fabrics exhibiting different colour values and fastness properties. The samples were prepared by dyeing with lac as a natural colourant. Two padding techniques used in the process, namely, pad-batch pad-dry techniques, under conditions. Aluminium potassium sulphate, ferrous copper sulphate stannous chloride mordants. effects of differing dye concentrations added to using pre- post-mordant method studied recorded. washing, light, rubbing, water perspiration dyed...

In this investigation, dyeing of cotton fabric with natural dye extracted from purple corncob was attempted by means pretreatment a cationic agent, 3-chloro-2-hydroxypropyltrimenthylammonium chloride (CHTAC). Maximum color yield results were achieved when the pretreated CHTAC at concentration 125 g/L, followed 100°C for 30 min in bath adjusted to pH 9. The influence meta- and post-mordanting AlK(SO4)2, CuSO4, FeSO4, gallnut subsequently explored. Compared unmordanted sample, enhanced K/S...

In this research work, natural dyes (Turmeric, Cinnamon, and Saffron) have been successfully used to dye cotton fabrics that are safe the environment health during manufacturing usage. Also these considered be nontoxic, nonpolluting, non-carcinogenic, eco-friendly. Copper sulfate (CuSO4) was as mordant in dyeing with Turmeric, Saffron on fabric. After dyeing, UV protection properties antibacterial efficiency of samples were evaluated morphological investigated using scanning electron...

Wool and silk fabrics were dyed using the water extract obtained from eucalyptus leaves; essentially higher utilization of dyestuffs shortening dyeing procedure was achieved as a result padding principle followed prior to drying. Simultaneous mordanting by FeSO4 shows brown-grey color different shades depending on dye concentration. The exploitation wool is than that silk, in both cases common "exhaustion" methods are better "long baths." ecological economical considerations natural discussed.

Natural dyes from Eucalyptus leaf extract, quercetin, rutin, and tannin were applied to silk fabric by pad-batch pad-dry techniques under different conditions. Ferrous sulfate was used as a mordant. The dyeing properties evaluated measuring K/S CIELAB values. In addition, the fastness evaluated. effect of at concentration levels with respect their colour strength also studied.

Purpose The purpose of this study is to investigate the possibility dyeing polyester (PET) fabric with natural dye extracted from annatto seeds using high temperature method. Design/methodology/approach PET was dyed extract by varying parameters (temperature, time, pH and concentration) determine optimum conditions. influences KAl(SO 4 ) 2 , FeSO gallnut mordants or a commercial UV absorber on colour yield fastness properties were further studied. Findings Optimum results obtained when at...

Silk fabrics were put through a process of dyeing with natural colorants extracted and used from the bark Garcinia dulcis (Roxb.) Kurz. Two padding techniques, pad-batch pad-dry, under different study conditions. The effects mordant agents on colorant in process, color values, strength, fastness properties silk fabric investigated results recorded following study. showed that values can be changed using various metallic salts as mordants. ranged fair to very good, while perspiration light...

To solve ecological and toxicological issues related to some synthetic dyestuffs, the potential application of a new thickening agent from wild taro corms natural indigo dye in screen printing process woven cotton knitted fabrics was investigated this study.
