The Effect of Ultrasonic on the Denim Fabric Worn out Process

Ramin Khajavi, Bita Novinrad and Amir Kiumarsi

In the presented research the effects of ultrasonic US on worn out process is under consideration. Samples of two different vats dyed denim fabrics chosen and were worn out with the aid of sodium hydrosulphite and neutral cellulase enzyme individually and together and the effects of ultrasound were investigated in parallel testes. Pictures were taken from samples by microscope and scanning methods and the amounts of brightness, color difference, degree of whiteness and color absorption of treated samples in US and ordinary environments were determined and compared. The back staining effects were also evaluated by the aid of degree of whiteness for samples. All the measured parameters were varied and increased between 50 to 98% for US environment and the back staining effects were declined in the presence of US significantly. It was concluded that the general properties of US wave especially in wet processes makes it applicable in worn out process for improving the efficiency and producing a different view, color change and fluffy look.
