The use of felt is very broad, ranging from craft applications to technical and industrial applications . It is a versatile material with many useful properties that is used in a variety of projects and industries .
Felt is made by matting animal hair or synthetic fibers.
When making felt from animal hair, wool obtained by shearing sheep is usually used. The wool is cleaned , washed and combed to remove dirt, grease and other impurities .
The wool is then treated with soap and water (manual) or heat (machine) and worked either by hand or machine to entangle the fibers . This creates a dense fabric that does not fray and is very durable. (see glossary: &#;&#;wool felt)
Synthetic felt is made from polyester or acrylic fibers . The fibers are processed by needling , chemical or thermal processes . (see glossary: &#;&#;needle felt)
When needling, the fibers are connected to each other using barbed needles. This is a purely mechanical process!
In thermal processes, the loose fibers run through an oven where they thermally bond. The thermal bonding can be done by the fiber itself (melting temperature) or by a chemical binder.
Chemical processes bind the fibers by utilizing the chemical binder by reacting with light, heat, moisture or solutions to bond the fibers together.
Making felt requires a lot of experience and expertise to achieve a high quality end product.
High-quality felt is made of wool .
Felt can either be 100% wool or contain a blend of wool and other materials.
Felt can be made from many different fibers or a specific fiber. Depending on the quality and intended use, different materials can be used.
Mixture of fibers
Felt, which is made from a mixture of fibers, can contain various components. These can be recycled wool (e.g. old sweaters), recyclable fibers, viscose/rayon (a wood fiber) or occasionally polyester.
Use of synthetic fibers
In addition to natural fibers, felt can also be made from synthetic fibers such as acrylic. This type of felt is typically used in craft projects.
General differences between industrial felts
Color differences and nuances of natural wool bales
The color nuances of industrial felts cannot be guaranteed during the production process. This is because they depend on the natural bales of wool used to make the felt. Each batch can therefore be significantly different.
Differences between white and gray wool
White wool is considered to be of higher quality and more durable than gray wool. These differences in quality can affect the uses of the felt.
Natural colors and possible irregularities
Industrial felts are generally not dyed and retain their natural colors. These range from a light beige to dark browns and grays.

No, felt will not fray.
Felt is a popular fabric used in many different projects, from clothing to decor. It has a fascinating history and manufacturing process so read on to discover everything you need to know about felt.
Made from natural fibres, felt is one of many manufactured fabrics. Unlike many of its counterparts, felt is not made by weaving. Instead, fibres are subjected to high levels of pressure and heat, with water added to the process to compress them into what we can recognise as felt fabric. The production process makes felt a durable material with a dense consistency as the fibres become permanently compressed and interlocked together.
There are many origins proposed when felt is discussed. Still, the most likely is that it originated in Asia around years ago. The historical evidence suggests that the Nomads first derived it when they found it to be a perfect fabric for tents and clothing and rugs to protect them from the elements. Even now, they use the material and develop a range of items like decorated slippers for the tourist trade. Another compelling story about the origins of felts is that in the Middle Ages, wool fibres were used to line shoes to provide comfort and warmth. As the footwear was worn, the sweat and heat from the feet combined with the pressure of walking created felt - but it is thought that production was not formalised, so they accidentally made felt without realising what they had discovered.
Traditionally felt is made from wool and other natural materials. This gives it a soft finish that has become synonymous with felt. One of the reasons wool is used is because of how easily it can matt together. Usually, this would be a flaw, but the felt production industry has played to the natural properties and made it a valuable asset.
As time has passed, new techniques have seen wool combined with synthetic fibres, and a superior result has been achieved. Most felt is now a blend of wool and either acrylic or polyester. Totally synthetic felt is also used, such as acrylic felt. This does nothing to hamper the strength, but it does make the finished fabric more pliable. Rayon is also a synthetic fibre of choice for some blends as this makes the felt softer and removes the prickly feeling that a pure wool blend can cause.
Making traditional felt from scratch is a labour-intensive process. First, the raw materials must be collected from sheep or other woolly-coated animals. Once the wool is harvested, the next step for most uses is combing and carding. The fibres go through a large combing cylinder that uses large steel nails as teeth. It is then fed into a carding machine where smaller teeth card the fibres into loose fibres. The next stage is to create rolls, and a device called a cross-lapper makes batts. The batts are then exposed to heat and moisture, which causes them to shrink and condense. Finally, the pressure is applied using large rollers, which creates the final smooth fabric we use in sewing and craft projects.
There are several different types of felt, including:
Felt can be used for a wide range of projects, as it is very versatile. It is suitable for insulating and creating warmth. It is also great for decorative goods, arts and crafts and soft furnishing. As previously mentioned, it is used in tents and yurts and clothing. It is a popular material with hobbyists who enjoy needle felting and hat making.
One amazing fact about felt is that it is highly flame retardant, and even if it were to catch fire, it is self-extinguishing. The material is very good at dampening sound and is absorbent and moisture-wicking. Felt is durable and easy to cut and work with. That said, it is pretty rigid and can shrink over time. The fabric can have a coarse feel, but this can be counteracted by adding synthetic fibres. Over time felt tends to go fuzzy, but it doesn&#;t fray. It is a cheap material with many uses making it a popular choice for sewing projects.
Felt is popular for arts and crafts projects. Many will have fond memories of classic green felt used to make a DIY craft garden patch. However, while this is still a much-loved pastime, there are lots of other crafting ideas you can create with felt and the variety of colours available.
