The maintenance and improvement of current properties and the creation of new material properties are the important reasons for the functionalisation of textiles with sol-gel organosilica coatings with particle diameters smaller than 50 nm (nanosols).25 Coating with nanosols enables the manifold alteration of their physico-mechanical, optical, electrical and biological properties of a textile surface (Figure 4.28). 

For example, sol-gel immobilised bioactive liquids such as cineol, camphor, menthol, evening primrose and perilla oil used to functionalise textiles afford either skin-friendly textiles with antimicrobial and antiallergic effects due to immobilised natural oils or textiles for therapeutic treatment of the respiratory tract by means of immobilised mixtures of high volatility natural agents such as eucalyptol, camphor and menthol.27...

With respect to hotmelts, biobased and biodegradable (Guo et al., 2010) types are available on the market, developed primarily for paper and cardboard. Table 1.8 gives an overview of hotmelts tested on textiles. Some were functionalised towards antimicrobial behavior and fire resistance (De Vilder et al., 2013). On cotton, good flame retardancy was obtained for the FR-functionalized Unirez using Eco-flam PU-228...

Abstract Enzymatic polymer functionalisation has entered its most fascinating period with development in this field largely at the basic research level and pilot scale applications. Development of enzymatic processes for the development of lignocellulose-based functional polymers has not been spared, ranging from textile fibres with novel properties (antimicrobials properties, hydrophobic properties, attractive shed colours, etc.) to fibreboards. Enzymatic processes are also being actively pursued aimed at developing functional polymers from lignin (a major by product of the pulp and process).
