  • The role of ultrasound in textile wet processes [Elektronski vir]
    Majcen Le Marechal, Alenka ...
    Despite of all problems which textile industry is facing in the developed world, textiles and their end products constitute still the worldćs second largest industry, placed only below food products. ... At least 10 % of the world's productive energies are devoted to this activity. Current textile wet processes suffer from two major drawbacks: large process time and low energy efficiency. Despite over 100 years of process improvements, the preparation, dyeing and finishing of textile continues to utilize large volumes of pure and clean water and therefore produce enormous amounts of textile wastewater which is heavily charged with unconsumed dyes and other chemicals. In order to overcome these problems various novel processes are being introduced or studied. Lately, textile wet processes assisted by ultrasound are of high interest for the textile industry, owing to following reasons: process acceleration and attainment of the same or better results than existing techniques under less extreme conditions, i.e. lower temperature and lower chemical concentrations. In this paper the fundamentals of ultrasound and its broad application in textile wet processes will be shortly presented. Results obtained with the use of ultrasound technology on laboratory scale textile wet processes like ultrasound-assisted dyeing (polyamide, cotton, wool, flax), scouring and bleaching will be discussed as well as the environmental aspect of this technology.
