Ultrasonic pilot-scale reactor for enzymatic bleaching of cotton fabrics.
The potential of ultrasound-assisted technology has been demonstrated by several laboratory scale studies. However, their successful industrial scaling-up is still a challenge due to the limited pilot and commercial sonochemical reactors. In this work, a pilot reactor for laccase-hydrogen peroxide cotton bleaching assisted by ultrasound was scaled-up. For this purpose, an existing dyeing machin...
متن کاملComfort and Handle Behaviour of Linen-blended Fabrics
Few can dispute the tremendous values of linen, which is one of nature’s greatest treasures. Linen is a longer-staple category, and as such the fibre is spun on a long-fibre spinning system. Due to the coarseness and stiffness of the fibre, linen fabrics are subjected to a strong bleaching action to reduce the stiffness of the fabric. Linen is also blended with other compatible natural and manm...
متن کاملEnzymatic Bleaching of Wood Pulp
The dark colour of kraft pulp after the wood chips have been heated at high temperature with NaOH solution is caused by lignin (a complex phenolic polymer) still attached to the cellulose fibres. Traditionally this pulp is treated with chlorine to bleach the pulp to make it suitable for paper making. Unfortunately this leads to the formation of some potentially toxic chlorophenolic compounds of...
متن کاملBleaching of cotton fabrics using hydrogen peroxide produced by glucose oxidase
Bleaching effect of cotton fabrics using hydrogen peroxide produced by glucose oxidase enzyme from Aspergillus niger has been studied. It is observed that enzymes are highly active at acidic pH under room temperature in terms of peroxide release during the reaction. Incomplete conversion of glucose by the enzyme results in discolouration of the reaction bath and the fabrics under alkaline pH co...
متن کاملEnzymatic Polishing of Jute/Cotton Blended Fabrics
Jute is a strong, stiff, natural fiber. When blended with cotton it makes a sturdy but prickly fabric due to protruding surface jute fibers. Samples of jute-cotton blended fabric were treated with commercial cellulases, xylanases and pectinases individually and in combination at various concentrations in order to smooth and soften the fabric. Enzyme treatment was carried out at 50°C in the pres...
