Bamboo fibre for handspinning is now available in 2 forms – one is a smoothly combed viscose top and the other is a rougher staple fibre. These require different methods of spinning.
Bamboo Viscose Top
Bamboo Viscose top is produced from Bamboo pulp (like other viscose pulp fibres). The bamboo is crushed and made into a pulp. Natural enzymes, hydrogen peroxide and chemicals are added to further soften the fibrous pulp.
The resulting pulp is wet spun and forced through a spinneret to produce fine bamboo filaments in the same way as other pulp based fibres. The bamboo fibre is white and silky in appearance and is a cool as a result of its high absorbency, due to the fibre being full of cavities.
As this bamboo top is very smooth and silky, similar in handle to the previous Rose viscose tops that I spun, I used a similar spinning method for this yarn.
I spun this yarn with a tight twist, using the smallest whorl on my Kromski Sonata spinning wheel, 14:1. This top is quite slippery so I loosened the tension on the brake in order to slow down the takeup speed as much as possible, so that I could spin finely without having the roving fly away on me.
I also turned the bobbin around, so that the brake was around the smaller whorl of the bobbin.
I used a worsted drafting method, taking care not to let the twist enter the drafting zone and go into the unspun roving.
I plied this as a 2 ply yarn, changing the wheel ratio to 9:1 in order to create a soft yarn.
A more detailed explanation on how to spin fine yarns can be found in my previous article on how to spin rose fibre.
