things, fabric construction and weight will influence the perceived ranking.
|General||Natural cellulosic fibre. A hard wearing fibre that has a degree of natural flame resistance and grown and processed in the UK. Currently only available in extremely limited volumes which are being blended with wool and used in upholstery fabrics.. It is unlikely to be in a position where sufficient fibre will be available for use in garments.|
|Available as:||Currently very limited in the UK. Nettle fibres are currently only available in restricted amounts. Used as mixed fibre blends, nettle is finding some applications in apparel where it is extremely hard wearing and durable. Volumes of fibre that are currently on the market are extremely small and limited. Incorporation into corporate clothing will take time to develop.|
|Colouration||Needs to bleach prior to dyeing, treat as cellulose. Nettle naturally has an off-white colour and will therefore require bleaching prior to any dyeing. Hydrogen peroxide bleaching as preparation of the fibre irrespective of the ultimate shade as this preparation route removes most of the extraneous matter in the fibre facilitating better levelling during the dyeing process. The natural colour nettle is often too deep to respond completely to the hydrogen peroxide treatment and a two stage sodium hypochlorite bleach then the hydrogen peroxide bleach is required. This is especially the case when light colours are required.
Nettle, like other natural cellulosic fibres, can be dyed with reactive dyes or in some cases direct dyes. If the clothes are to be used for work wear where more durable dyes are likely to be required, reactive dyes, vat dyes or sulphur dyes would be the selection of choice.
|Shrink resistant. Good dimensional stability, fibres tend to have higher strength when wet than dry.|
|Resistant to pilling. Nettle fibre are extremely durable and resistant to abrasion and pilling.|
|Can be laundered at high temperatures, prone to creasing. Nettle can withstand laundering at high temperatures, these should only be used for heavily soiled garments. Flax fabrics are prone to becoming creased during washing and this will requires the use of a hot (steam) iron during pressing. Dyes have a tendency to bleed and suitable separation during washing should be encouraged. Chlorine based bleaches can be safely used on cotton, although dyed fabric should use a colour safe bleach. Tumble-drying requires a high temperature setting. Like cotton, nettle can be treated with a crease resistant finish which can improve the "easy care" nature of the fabrics. Treated fabrics should be laundered in accordance to instructions as these may recommend lower heat settings during drying and ironing.|
|Applications||Jackets and suiting. Blended with other fibres it can be used in some apparel such as dresses. Current heavy weight fabrics more suitable for jackets where hard wearing properties can be exploited.|
|End of life
|Can be disposed of using all end of life opportunities. A natural cellulose fibre that can be handled in the same way as other cellulose fibres. The fabrics may potentially be reused or re-manufactured and can also be used as a source of cellulose feedstock for regenerated cellulose products. Being naturally biodegradable, the fibres can be composted if required.|
