“…[22][23][24] Cellulosic substrates like ramie, cotton and hemp have received considerable attention for their functionalising and coloration aspects. [25][26][27][28][29][30][31] These resources are naturally abundant and the presence of rich -OH groups in their molecular structures 32 is also beneficial. Cellulosic materials possess enormous application potential for products such as apparel, bags, footwear, upholstery, automobiles, filters and packaging.…”

Ecological nanosilver-based colours were biosynthesised from the heartwood of European yew (Taxus baccata) trees for the dyeing of flax woven fabrics through the implementation of in situ synthesis protocols. The produced lighter brown yellow to darker brown-yellow coloured nanosilver particles on flax woven fabrics were characterised in terms of morphological observations, metallic compositions, elemental mapping, chemical interactions, the presence of silver nanoparticle (AgNP) concentrations and colour characteristics with associated performances. The presence of AgNPs was clearly observed by morphological studies of the coloured substrates. Quantitative analysis of the products also confirmed the significant presence of AgNPs. The results demonstrate that the uniform dispersions and strong attachments of AgNPs in cellulosic flax woven fabrics are due to surface plasmon resonance characteristics. The incorporation of different concentrations of metallic AgNPs plays a significant role in producing versatile colour appearances on flax woven textiles with improved colour durability. The overall results offer new routes for sustainable structural colourants in the industrial dyeing of cellulosic materials.

“…Bast textile fibers processing and spinning technologies promote microbiological pollution [5,6]. Elementalized hemp is suitable for use in textiles for various purposes [7] The works of a number of authors were aimed at finding solutions for the resistance of textiles to biological degradability during exploitation [8][9][10].…”

The aim of research was to observe and to describe biodestructions of fabrics that usually used inside a home, to estimate the destruction (total number of destruction “N” and destruction index “K”). The samples of fabrics were placed into a thermostat in sterile Petri dishes on moistened sterile filter paper in order to stimulate the microflora occurred on fibers. Incubation carried out in a thermostat at a +24-28 °C, humidity of 90-100% and exposed for 8 month. The samples examined with a microscope. As a result of the study of fiber’s damage, the types of damage were identified as follow: layering, fretting, mottling, fouling, spotting, swelling, granular disintegration, delamination, thinning, and damage of the fiber wall. Initially the most destructed was detected sample of natural silk and hemp according to the highest value of destruction index K. However, after 8 months of exposure, this sample turned out to be the most resistant to biodegradation. The data obtained based on the evaluation of the biostability of fabrics made from various textile fibers showed that the usage of natural silk, hemp and polyester able to supply textile with resistance to biodegradation by spontaneous microflora.
