Effect of Sliver Nanoparticles on Wool Fibre

Sliver nanocolloids have been synthesized by chemical reduction of sliver salt solution, characterized by SEM usage of nanoparticles. Sliver nanocolloids are treated with wool fibres and dyed wool fibres (direct and acid dyes). The physical properties, colour strength, and fastness properties have been studied for dyed wool fibres and ordinary wool fibres. It is observed that the fibres with nanotreated fibres have better strength than untreated wool fibres. It is also observed that there is considerable improvement in colour strength and colour fastness of silver nanocolloids-treated wool fibres (dyed).</jats:p

Single-stage antimicrobial and crease proof finishing of cotton materials

A study of single-stage antimicrobial and crease proof finishing of cotton materials has been reported. The bleached and reactive dyed cotton woven fabrics have been selected for this finishing process. The various concentrations of DMDHEU and triclosan and temperature have been selected to analyze the crease recovery and antimicrobial properties of fabric using Box–Behnken design. It was observed that increasing the concentration of DMDHEU and triclosan increases the crease recovery angle. It is also observed that the breaking strength retention properties have been reduced when increasing the concentration of DMDHEU and triclosan and temperature. It is also found that the antimicrobial effect was increased when the concentration of DMDHEU and triclosan increased. </jats:p

Tensile Properties of Copper Core Yarn

In this investigation the complex copper core spun yarn (Cotton Sheath and Polyester Sheath) of 179, 118, 98, and 84 tex count of copper core yarns were produced by Dref friction spinning machines and the count of 74 and 59 tex of copper core yarns (cotton sheath and polyester sheath) were produced by ring spinning machines with core attachments device for electromagnetic shielding yarn production purpose. The article reports the effects of the process variables on tensile properties of the copper core yarn as well as individual core and sheath components. Various parameters such as Spinning drum speed, the sliver material, core materials, and count of the yarn were changed to investigate how various parameters affects the tenacity of the complex copper core spun yarn. </jats:p

Electroless nickel plated composite textile materials for electromagnet compatibility

35-41A study on electromagnetic shielding effectiveness of electroless nickel plated copper core with polyester sheath yarn composite fabrics through Taguchi design and ANOVA has been reported. The electromagnetic shielding effectiveness of these conductive composite fabrics has been measured in the frequency range 200 - 1000 MHz using network analyzer equipment. It is observed that with an increase in palladium chloride and nickel (II) sulphate concentrations, the shielding effectiveness increases. The ANOVA results show that the time and temperature are negligible factors as compared to other factors

Electromagnetic shielding effectiveness of copper core yarn knitted fabrics

149-154A study on electromagnetic shielding effectiveness of copper core yarn knitted fabrics through Taguchi design and ANOVA has been reported. The copper is selected as the conductive filler to produce copper yarns for making knitted fabric. The electromagnetic shielding effectiveness of these knitted fabrics has been measured in the frequency range 20-18000 MHz using network analyzer equipment. It is observed that with an increase in tightness factors, wale density and course density, the shielding effectiveness increases. The interlock knitted fabric has better electromagnetic shielding effectiveness than rib and plain knitted fabrics. With an increase in copper wire diameter, a decrease in shielding effectiveness is observed
