Yarn
Barbie
What I show here is a filament yarn originally created for dolls hair. I was looking for a high-gloss yarn for a carpet and finally found this. A filament yarn which is made by pressing a liquid substance through the spinnerets. You then get an endless yarn.
A silk worm does the same when he makes a silk cocoon. The filament of a silk worm may be as long as 900 metres.
This is a synthetic raffia, made of a synthetic polypropylene, usually high-gloss and available in several colours. The production process is similar to that of plastic foil or plastic bags, and also to filament yarn.
Natural raffia is a product of the Raphia palm from Africa. The palm leaves are stripped, dried and dyed if necessary.
A filament yarn is made by pressing a liquid substance through the spinnerets. You get an endless yarn in this way. When the spinneret is smooth, the fibre will be smooth and glossy. There are also spinnerets with texture that gives the yarn a different look, for instance more voluminous.
Filament yarn is either synthetic like polyester, or natural like viscose or latex.
