I ran across this website that might be interesting to other fiber-geeks. Natural Fibres is the name of the site and you can see from the first page that they are interested in informing about all aspects of natural fiber.
“We are now seeing a growing movement away from petrochemical based fibres back to natural fibres. There are three reasons for this. Petrochemical based fibre production has undergone continuing rising costs. Synthetic fibres rely on precious non-renewable resources and incurs environmental costs in their production. Petrochemical based products pose a health risk in most applications, both from direct exposure and also from secondary exposure through soil, water and air pollution.
Natural fibres are either extracted from plants from the leaf, the inner bark or fruit/seed crop, or from animal wool/hair, or insect cocoon or from mineral product. Plant sources of fibre include cotton, hemp, kenaf, ramie, sisal, flax, linen, lime, jute, seagrass, and abaca. Animal sources of fibre include sheep, alpaca, llama, goat, and camel, and can be either wool, hair or leather. Insect fibre is predominantly from silkworm cocoons.”
There are several tabs on the right hand side that will bring you to all sorts of information. Enjoy!!
