The textile industry is very diverse, heterogeneous, and characterized by high consumption of water, fuel, and chemicals. Environmental problems are mainly associated with wastewater. With regard to globalization and scarcity of water, wastewater treatment and recycling possibilities in the textile industry are of the highest importance. In this chapter, raw materials and processes used in textile industry are briefly discussed, with special attention given to characteristics of textile water supply and wastewater produced from different process steps. The general characteristics of textile wastewater and wastewater-treatment technologies are described and reuse possibilities are discussed.

n overview of methods for cellulose fibres functionalization in order to introduce antimicrobial activity is presented. Antimicrobial finishing together with some strategies for the functionalization of fibres using biodegradable polysaccharides such as chitosan are presented. The methods used for the microbiological testing of these fibres are discussed and the current disadvantages of these methods indicated. A new strategy for a reliable methodology regarding the antimicrobial testing of oriented fibre-based polymers such as cellulose is discussed.

The paper investigates the enzymatic hydrolysis of three main allomorphic forms of microcrystalline cellulose (I, II, III) using different cellulases. The efficiency of the enzymatic hydrolysis was estimated by the amounts of reducing sugar (HPLC-SEC), and by the changes in the average particle sizes of the cellulose allomorphs/crystallinity (X-ray diffraction; optical and scanning electron microscopy). The crystalline structure of allomorphic forms I and II did not suffer significant modifications, while cellulose III recorded a partial return to the crystalline structure of cellulose I.
