Twining is the intertwining or 2 or more yarns.

When the colours of the fibre are mixed in the pre-yarn it is called Jaspé’. When the yarns, mostly of equal thickness, differ only in the variety of colours, it is called Mouline’.


A core is wrapped around by another colour after which the woollen yarn is felted in such a way that the 2 colours intertwine. Originally this yarn was meant to produce a cheap yarn with a core of minor quality, this yarn was not cut. The technique is also used for yarns not allowed to stretch or shrink, for example for aeroplanes. The core is made of glass fibre and the wrapping is wool or another material. Another known core spun yarn is Lycra where an elastomer is wrapped by another yarn, often used in tights or other stretchy materials.

The existing techniques for felting the thread are: Periloc (see drawing) and the traditional way of washing the yarn with soap.

cabled yarn

Cabled yarn consists of 6 loose single yarns, intertwined in twos, and then these resulting 3 threads are joined together again forming a yarn with a rope-like appearance.
