The applications of enzymes in textile industry are presented. The enzymes suitable for textile processes (oxydo-reductases and hydrolyses) as well as the type of enzymatic treatments applied on textile materials have been described. Some results obtained by using biotechnology in the textile field are presented. The development of textile biotechnology in the last decades due to development of knowledge in the field is pointed out. The advantages and disadvantages of using enzymes in different steps of textile materials processing are discussed. The effects of the textile biotechnology on the environment are underlined. As a generalconclusion, the biotechnology may assure new ecological procedures in the textile materials processing.
