Textile industry has beentraditionally associated with environment pollutions and consumption of largervolumes of water. An increasing public concern in environmental issues hasprompted the development of sustainable textile dyeing technologies that wouldreduce the generation of wastewater as well as the use of toxic chemicals andsubsequently satisfy regulatory and legal requirements. This concerns are notonly limited to textile dyeing processes and they extend over various methodsof fabric surface functionalization and modification. Emerging areas ofadvanced functional and smart textiles are referred to the development offibers and fabrics that provide a range of properties from barrier materials toelectronic devices that could be approached through surface functionalizationof fabric. At the same time, emerging novel advanced textiles are seen assustainable and biodegradable materials with a minimal environmental impact.

This presentationconsiders unique characteristics of nanocellulose (NC) such as a large specificsurface area, strong affinity to cellulosic surfaces, fibrillary mechanism ofadhesion, and the reactive surface arising from abundant hydroxyl groups forvarious add-on functionalities bound to conventional textiles provided by NChydrogels as functional coating materials. NC hydrogels produced byhigh-pressure homogenization could be deposited on cotton fabrics by padding,draining or printing methods. We demonstrate that a thin layer of NC is used asa binder for dyes, nanoparticles, nanowires, capsules, and reactive molecules;and a protective layer for functional fabrics in laundering.
