Wool and felt.  Some facts for the curious ones.

Wool is animal fiber and comes from different animals. It may be called different terms depending on the animal it comes from, but it is still wool. It was wool people have begun to make their clothes of well before they discovered the usefulness of plant fiber. First, they shaved or cut the fur off the animals they killed for their meat, but then they discovered that the wool grows over and over again and it may be worth taming some of the animals and cutting or combing them instead of chasing them. Sheep and goats had given wool to the first threads, but people also get wool from camels, dromedaries, lama, alpaca and rabbits. Wool and garments made of it are the faithful companions of humanity since ancient times. Wool is water repellent, insulating, fireproof (glows but not burns), silencing, warming and glorious.

Felting is a very practical way of making textiles. You do not need any spinning machines, looms or knitting machines and can save at least 2 washes when compared to production of wool yarn. It takes less work and less energy to pull than to spin and weave / knit. Felted clothes are usually lighter than knitted or woven clothes in a similar model because you can wipe it thinner without losing heat or durability. It feels like a good coat or thinner wool when wearing felted clothes. Felted clothes are light and you will not get hot or frozen in them, great for robes and coats but also for lighter garments and dresses. All felted items are both dirt and water repellent, which is useful for both clothes (you do not have to wash the wool too often, including knitted or woven garments) and interior items. Felted wool is very durable. After a few weeks of use, all small bumps disappear and the garment looks the same year after year.

Nunofelting (derived from Japanese “nuno” fabric “) is to allow the wool to coalesce with a fabric, usually sparse or thin. The natural materials are best suited for this, but also synthetic materials can be nunofelted with. This technique provides great opportunities for clothing creation and artistic expression. This technique became known / discovered in the second half of the 1900s and is relatively new in the textile world and has great potential to explore and develop.

You can felt wool of most cloven-hoofed animals, but sheep wool is best suited for this.

You can tarnish wool and other fibers, for example flax or silk. It provides new interesting textiles with properties of all the fibers used.

Knowing if things are well-felted is simple: they do not lose much wool (some knocking occurs almost always in the first few weeks when you start using a worn out garment or item, but it will disappear soon), The object feels whole and compact, there is no resilience when squeezing it between the fingers, no “fungus” or frenzy feeling. It is not possible to see separate hairs on even the smallest objects. The cut edges look like a whole, no separate fibers are visible. The surface is not “hairy” but smooth although it may have a spiny texture due to shrinkage. Well felted things are water repellent and very difficult to wet.

The wool grows well when the animal is doing well. With the long selection work that people had done since the first animals became tame resulted in an impressive number of different wool types have occurred. Some wool types are better suited to felting than the others. When wool is being felted, the small cells (scales) on the surface of each hairline come in close contact, almost a grip, with cells on the adjacent hairs and become more or less stuck. Wool can be felted dry, but it feels much better when it is wet, so it is important that the animals presented to give long, thin or large amounts of wool are cut regularly. Otherwise the wool is destroyed and becomes difficult to handle, and besides, the animal suffers when the thick coat fills up and draws in the hair roots. When the wool is wrapped, it is hard to shorten or comb and the finer hairline may break during treatment. In Sweden there is a law that all sheep must be cut at least once a year. To get good wool suitable for handicraft and textile production you must cut the sheep twice a year, usually in spring and in autumn. Autumn wool is usually even in thickness and is best suited for felting, but spring wool is useful after careful sorting too.

Felting is to use the wool properties, follow the material … Felting is probably the oldest textile technology in the world. You use the wool’s ability to soothe but do it under controlled conditions. The wool is cut, sorted, cleansed, carded, combed or whipped and then laid out so that all fibers are able to attach to one another. The laid wool is soaked with water mixed with soap and processed mechanically (flap, rolled, massaged) to help the fibers to get a better grip on each other. This moment is called felting. Then you use another of the wool properties – it can shrink and shrink. When the feltmaker sees that the piece is felted, i.e. holds together properly, he or she starts the shrinking. There are many ways to shrink the wool, with varying temperatures and tougher mechanical processing or just with any of these factors. An object usually shrinks between 20 and 50% of its original size. Felt + shrink = felted!

All animals have dead hairs in their fur, even humans. People can comb hair and get rid of the dead hairs, but sheep or camels can’t. Therefore, part of the dead hair, or barley hair, remain in the trap. Before the animal is cut, those fibers are placed between the”living” fibers and prevent the felting – they cannot be fouled! But when you wipe the wool that has a lot of joints, there may be some loose hairs on the surface and the objects fall. If you wrap yarn of such wool it will probably feel sticky. People have worked with the breeding to get as little dead hair as possible and some sheep breeds miss them almost completely. Wool with even fiber thinness is best suited for all types of handwork. The thinner wool is the gentler and thin things can be worn off.

I use wool of Swedish sheep breeds Finull sheep, Jämtlandsfår, Värmlandsfår, Gotland, Rya and Klövsjöfår, and wool from different European sheep breeds and merino wool from non-susceptible to mulesing and other textile fibers such as flax and silk. Fabrics for nunofelting are either recyclable or ecologically labeled.
