New soybean protein fibres (SPF) are biconstituent fibres contain- ing 5−23% of soybean proteins and 77−95% of polyvinyl alcohol (PVA). Soybean proteins used for the manufacture of SPF are by- products of the soybean oil production. The chemical and supra- molecular structure of soybean proteins, the process of manufac- ture of SPF fibres, and their properties are described in the article.

The expected biodegradability of SPF is based on the well-known biodegradability of soybean proteins and polyvinyl alcohol as well on the biodegradability of the films made from soybean proteins and polyvinyl alcohol. Yarns made from 100% SPF and 100% cot- ton, and fabrics made from 100% cotton fibres and from cotton fi- bres in warp and SPF in weft were buried for 21 days in humus soil with temperature 30 °C, relative humidity 65% and pH 6. The con- ditions under which rapid biodegradation of pure cotton textiles took place induced only a slight decrease of mechanical properties of the SPF yarn. ATR FT−IR spectra displayed a reduction of in- termolecular hydrogen bonds between protein-protein, PVA−PVA and protein−PVA segments and, consequently, the increase of diso- rientation in the upper layers of soybean protein fibres. The content

of SPF in weft direction was responsible for the prolonged retention of mechanical properties and structure of the fabric as a whole.

Keywords: phytoprotein fibres, soybean protein fibres (SPF), poly- vinyl alcohol (PVA), degradation

The influence of reactive dyeing on the silver adsorption of antimi- crobial agent RucoBac AGP on a cotton fabric was investigated for the research purpose. RucoBac AGP was applied on a cotton fab- ric using the exhaustion method. For a comparison, RucoBac AGP was applied on fabrics treated in a blank dyebath which contained all auxiliaries except for the dye. The quantity of silver, the antibac- terial efficiency and wash-fastness were determined for functional- ized fabrics. The whiteness and colour change of silver treated cot- ton fabrics were investigated as well. The research results show that dyeing with a reactive dye causes higher adsorption of silver on a bleached/mercerized cotton fabric and its antimicrobial efficiency.

The changes in the whiteness and colour of the fabric are more vis- ible when treating cotton with a higher concentration of RucoBac AGP.

Keywords: cotton, reactive dye, nanoparticles, silver, adsorption

Smart textiles, from fibres to fabrics with integrated special elec- tronics, are nowadays used to develop smart clothing. In this pa- per, some examples for future design and development are present- ed. The “safety vest” with integrated photovoltaic cells and LED lights is included as well. The prototype of a “safety vest” was de- veloped at the Department of Textiles, Faculty of Natural Scienc- es and Engineering, University of Ljubljana and was presented at the LOPE-C Conference (Large Area Organic & Printed Electronic Convention) in Frankfurt as one of five best international univer- sity contributions.

Keywords: safety vest, smart textiles, conductive fibres, photovol- taic fibres, “printing dress”
