First I want to point out that the so-called fulling of high quality yarn is ” water treatment ” (read here for more). Indeed to cashmere is not made a real fulling as wool yarns. The cashmere effects must not become matted as the fiber is so delicate that the yarn would ruin.
The treatment consists in the wash water in tanks, industrial, or even in a normal washing machine, the yarn in skeins with water alone or at most with little fabric softener. This simple step allows the fiber of cashmere to relax and unwind.
The cashmere yarn for knitting in cones you can work directly with knitting needles or crochet, but I highly recommend you make with the help dell’arcolaio skeins, or balls and leave to rest a few hours before the processing.
In fact, when the yarn is put into fortresses remains rather “tight” around the cone. Putting it in hanks or in balls, they are allowed to breathe and swell until it returns to its original state.
When you have finished working with the boss you should wash it before wearing it. Wash the cashmere is a long process but very simple. Cashmere is put to soak in a basin of cold water or warm water with a little fabric softener for delicate items. You leave it for at least 3-4 hours , after which it is removed from the tray by removing excess water without wringing his head (I recommend) and put it out to dry by resting on a plane.
Never hang a cashmere sweater to dry, the weight of the water it could deform more and not resume its original shape.
If you work the yarn into skeins can wash the coils directly before making the boss, the washing process is the same.
As I said, the process is long , but it is a very fine fiber and very expensive it might be worth. Do you think the balls to make it part anyway fortresses. The yarn is put into coils, then the treatment is washed using water, after it is put in balls. This means that undergoes at least three processes, sometimes four, and each of these processes has a cost quite high since it is cashmere. Working the yarn package savings the cost of all these processes.
I hope these tips you can be useful.
