Also known as Soybean, this fibre is manmade, but from a natural source. Soya protein is processed in to fine filaments to make this combed top. It was invented by Henry Ford in 1937, and was primarily used for car upholstery, because its anti-UV properties mean it fades far less quickly than silk or viscose. The rise of true synthetic fibres meant it disappeared from production, but was revived in 1998 when interest in non-oil based fibres was starting to increase. Treat it as you would spin silk, it will make a yarn with a beautiful shine and lovely drape.
This manmade fibre is synthesised in the same way viscose. Milk Casein protein is dissolved, and then forced through fine nozzles to form filaments. It was originally made in Italy and the USA in the 1930s as a substitute for wool, but declined in popularity. This fibre is soft and with a moderate staple length, and will turn in to yarn that has a lovely shine.
This fibre is hand dyed in small batches, where more than one braid is available they will have been dyed at the same time, using the same dye stock, but my dyeing technique produces braids with subtle variations.
These fibres have been dyed to exhaust using acid dyes, and then rinsed using hot water and detergent. I recommend you hand wash your spun yarn in warm water, using a mild pH neutral detergent. The no-rinse wool washes seems to be the most prone to causing bleeding so are best avoided.
