Effect of ultrasonic energy in washing of medical surgery gowns

Effects of ultrasound on oily sludge deoiling

“…Fig. 2 shows that 40 • C was the optimum washing temperature for ultrasonic cavitation [7]. Because the cavitation threshold was enhanced with increasing frequency [9], 28 kHz was more suitable for oily sludge deoiling than 40 kHz.…”

“…When the temperature is above 40 • C, oil content increases. This is because when the temperature is too high, the intensity of the ultrasonic cavitation is weakened, which causes the process of separation of crude oil from solid particles to be retarded [7]. The cavitation effect is maximum at low temperatures.…”

Directions of the Finishing of Fibres and Textile Development

“…Since the 1990s many scientific works have been conducted on the use of ultrasounds (cavitation phenomena) in wet textile processes [37 -55]. The research on ultrasound-assisted textile treatment concerned: n the washing of fibres and textiles [38 -39], leather [52], and medical tools [43]; n cotton bleaching [42]; n the dyeing of cellulose fabrics [37,55], woollen fabrics [44, 45, 47, 50 -53], acetate fabrics of cellulose fibres [49], and textile products from PAN fibres [51].…”

Ultrasonik ve Klasik Yıkama Yöntemlerinin Dokuma Kumaş Termal Özelliklerine Etkilerinin İncelenmesi

“…Ultrasonik enerji ile yýkamada ana prensip, sývý banyosu içerisinde oluþan yüksek frekanstaki milyonlarca kabarcýðýn kumaþýn yüzüne etkisi ile temizleme saðlanmasýdýr. Ultrasonik yýkamanýn temel parametresi geçici boþalma (kavitasyon)dur [1][2][3][4][5][6]. Kumaþlarýn boya alma özelliklerinin arttýrýlmasý ultrasonik enerjinin yaþ iþlemlerde kullanýlmasýyla mümkün olmaktadýr [7][8][9][10][11].…”
