As Super short fibers (engl. "Ultra-short fibers") are in the area of the natural fibers , especially to the bast fibers belonging stem fibers such fibers referred to, having a length of a few millimeters to about one or two centimeters.

This definition is to be seen in relation to the definition of short fibers that is common for this area of ​​natural fibers , the length of which is between 40 and 100 mm.

Applications

In the production of bast fibers from hemp , flax and other fiber plants Super short fibers fall in fiber digestion in addition to long and short fibers to. When processing hemp straw, about 56% shives and 28% hemp fibers are used , with the latter about 3% being super short fibers.

The super short fibers are used for various purposes in the course of recycling residues and can thus add value to the use of natural fibers. Some natural super short fibers are used, among other things, together with the fiber dust as dietary fiber in animal feed . Due to their large surface area, such super-short fibers made from natural vegetable fibers can be used for general applications as well as absorbents for drilling and oil sludge and can replace asbestos in brake linings .

Super-short fibers are used as reinforcement fibers in fiber composite materials and natural fiber-reinforced plastics , as they are well distributed when they trickle in and can also be used in the injection molding process .
