Descrizione principale (Inglese)

In the production of textile fabrics and products, various types of treatments are applied, through which their physicochemical properties are changed. These treatments are strictly specific for different types of textiles. In addition to the application of a number of finishing techniques, other important treatments include the dyeing and printing processes, through which the color variation and patterning of the fabrics are obtained. Several techniques are distinguished: classic dyeing, in the so-called dye bath; rotary screen printing, in which the dye paste is applied to the fabric by means of a series of engraved cylinders and screens and the digital technique of printing on fabric by spraying the dye – Ink Jet Textile Printing Technology (IJTPT). The subject of this study is a comparative analysis of classical dyeing and inkjet printing of cellulose fabrics, with an approach to a new textile printing technology by spraying the dye onto the fabric and creating new textile products, with an ecological goal: significantly reducing water and energy consumption, the amount of dye and minimal harmful impact on the environment. Keywords: cellulose textiles, inkjet printing, reactive dyes
