“…Bast fibres sit within the intersection of sustainability and performance materials; they are obtained from stems of dicotyledonous plants and are characterized by their thinness, flexibility, and strength [5][6][7]. Cellulosic bast fibres are generally less expensive than synthetic fibres and possess competitive mechanical properties, such as high tensile, due to the volume fraction of cellulose [8] and the microfibrillar orientation [9].…”

Development of sustainable fibres for high performance applications is challenging because of the high mechanical strength properties demanded by such fibres and the general lack of such properties in natural fibres. The mechanical properties of Himalayan giant nettle (Girardinia diversifolia L.) fibre are measured and compared to those for European nettle (Urtica dioica L.) fibre. The mean length of G. diversifolia fibre is substantially higher than U. dioica fibre, and the longest fibre length reported for any bast fibre. G. diversifolia and U. dioica fibres have similar cross-sectional area, but G. diversifolia fibre is a wider, flatter, oval shape with a significantly wider lumen. G. diversifolia fibre display a generally linear stress/strain curve. Ultimate stress value for G. diversifolia fibre is over twice that of U. dioica fibre, and the highest of any bast fibre reported. G. diversifolia fibre also displays greatest strain at failure of any bast fibre. Young's modulus for G. diversifolia and U. dioica fibre are similar. Himalayan giant nettle fibres display tensile properties that offer potential in high performance applications.

“…Distinguishing between the bast fibres is possible based on X-ray microdiffraction method, but as the method requires the use of a synchrotron it is not readily available; moreover, it is costly. Bergfjord and Holst [19] proposed a simple procedure for identifying different bast fibres measuring the fibrillar orientation with [13] polarised light microscopy and detecting the presence of calcium oxalate crystals (CaC 2 O 4 ) in association with the fibres. This procedure required a small amount of fibre material.…”

Nettle is a common herbaceous plant, which regroups 30-45 species. It is part of the Urticaceae family such as ramie (Asian nettle, Boehmeria nivea) and belongs to the genus Urtica. The stinging nettle (Urtica Dioica) is the most prominent species in Europe and Himalayan ranges. This fibre also belongs to an ancient textile fibre. In this chapter deals with different aspects of sustainable process of production of fibre, methods of fibre extraction and their advantages, properties of nettle fibre, products from nettle and its blends. A comprehensive effort has been made to revamp the potentiality of sustainable development of fashionable textile and industrial materials from nettle fibre as well as form its byproducts. Overall, chapter covers various nettle-based handicraft and apparel products for luxury sector and their proper disposal.Keywords Nettle fibre · Extraction of nettle fibre · Properties of nettle fibre · Sustainable nettle textiles · Application of nettle fibre

“…There are two groups of fibre identification methods, separated in terms of availability, cost, and practical use: (1) methods using complex scientific devices (Chen et al 1996;Durán and Angelo 1998;IWTO-58 2000;Bergfjord and Holst 2010;Rezič et al 2010;Paolella et al 2013) and (2) methods using subjective sensory evaluation of their form, smell, staining, and color (ČSN 1976;Goodway 1987;STN 1993;ASTM 2007;TAPPI 2008).…”

a Simple, rapid staining analytical methods with visual color assessment are the most used in practice, but they involve problems including subjective error, low accuracy, qualitative results, and the necessity of using many kinds of stains and a great deal of morphology information for correct identification. A method of objective fiber identification using color vectors of a microscan from stained fibre digital photography is described in this report. A model set of cellulose fibres was prepared: groundwood; sulphate pulp; Whatman paper; and rag fibres. The objective micro-colorimetric method, using RGB (red, green, blue) vectors with discriminatory analysis, reduced the number of stains to 1; requires no morphological information; and the discriminatory power (dp,) of this approach is up to 95 to 100% of correctly identified unknown samples with one color vector R or B. A dp value of 100% was achieved when using 2-P or 3-P combinations of R, G, and B.
