There is a type of wool felt balls which are made of 100% natural wool. They are widely used as wool felt dryer balls and various decoration balls.

Pressed Wool Felt - Produced According to SAE Standrad

Pressed wool felt production is an complex process, in our daily life, if you wash the woolen sweater by hot waters, the woolen sweater will be shrink, harden and solid, this is the basic principle of wool felting, so the pressed wool felt is also called wet wool felt.

Wool fibers have several barbs, which cannot be seen by our eyes. When the wool fibers are treated by hot water process, the barbs will be open and erect. After a continuous process of pressure, moisture and vibration, the barbs will interlock together and form a felting condition. The grade of pressed wool felt is according to the SAE standard, which determines wool content, density and other physical and mechanical properties of the felt.

The pressed wool felt can be supplied in sheet or rolls. It is the raw material of wool felt polishing wheel and wool felt bobs.

Needle punched wool felt is a kind of felt made by vertically needling fibers together to achieve a desired thickness and density. Needle punched felt is commonly manufactured from wool, synthetic and other re-processed fibers. Also, the needle punched wool felt can be made of 100% wool.

Compared needle punched wool felt with the pressed wool felt, you can find the difference between them.

The production of pressed wool felt is commonly through moisture, pressure and vibration processes. The needle punched wool felt is mainly treated by needle machines.

View the cross-section of wool felt, we can find the fibers of needle punched wool felt lay vertically, while the fibers of pressed wool felt lay horizontally.

Pressed wool felt is mainly used in the industrial applications for polishing, sealing and furniture protection, while the needle punched wool felt is widely used in the daily life, such as the wool felt insoles, wool fet placemat, wool felt sauna hats and other wool felt products.

Needle punched wool felt is more economical than the pressed wool felt. Some of the needle punched wool felt has less wool content than the SAE standard pressed wool felt. F-15N and F-26N are the two standard type of needle punched wool felt. The 100% wool needle punched wool felt is more expensive than the low wool percent wool felt.
