Effects of ultrasonic energy on dyeing of polyamide (microfibre)/Lycra blends

Influence of Ultrasonic Waves on the Processing of Cotton with Cationic Softener

“…Recently, considerable efforts have been devoted on the application of ultrasonic waves in different textile processing, including desizing, bleaching and scouring of natural textiles [5][6][7][8][9][10][11][12][13][14][15], dyeing of natural as well as synthetic fibers [16][17][18][19][20][21][22][23] and dye effluent decolorization [24,25].…”

“…Dissolved or entrapped gas or air molecules are expelled from fiber capillaries and interstices at the crossover of fabric into liquid by cavitation, thus facilitating dye-fiber contact. The rate of diffusion of the dye inside the fiber and chemical reaction between dye and fiber are also accelerated by piercing the insulating layer covering the fiber [16][17][18][19][20][21][22][23]. Decolorization of textile effluents takes place using a combination of ultrasound and electro-oxidation methods [24].…”

The Effect of the Ultrasonic Energy on Dyeing a Polyamide Material with Reactive Dyes, Including a Different Chromophore and a Reactive Group

“…Sonication is positive effect on the cellulosic fibre being dyed by the reactive dyes and in terms of fastness features, [5,6] in the disperse dye as well as the PES dyeing, sonication does not have any effect on the fibre's Tg value, dyeing exhaustion rate [7]. In reactive dyes PA and PA/lycra mixture material's being dyed, there is a dye adsorption, yet there is not an effect on the fastness features of the dyeing [8][9]. In the dyeing of Nylon 6 with the reactive dyes, the colour strength of the dyeing increase, the diffusion is better in the dyes due to the de-aggregation in the dyes molecules and the ultrasonic energy can be more effective on the dyeing -fibre covalent bond fixation [8].…”

Effect of ozone and ultrasound on the fiber properties of angora rabbit

“…[14][15][16] Ultrasonic energy is also used in textiles (e.g., dyeing) to speed and develop textile processes. 17 Several articles and studies have appeared in this field that report some savings in energy, chemicals, and processing time for wet textile processes with the use of US. 10,[18][19][20][21][22][23][24][25] The effectiveness of US is lower than that of ozone for bleaching when the frequency of US is taken into consideration.…”
