What is the difference between steel fiber and fiber?

Steel fiber refers to the aspect ratio (the ratio of fiber length to its diameter) that is made by cutting thin steel wires, shearing cold-rolled strip steel, milling steel ingots, or rapid condensation of molten steel. When the fiber cross-section is non-circular, the equivalent cross-section circle is used. area diameter) of 40 to 80 fibers.
Fiber refers to a substance composed of continuous or discontinuous filaments. In plants and animals, fiber plays an important role in holding tissues together. Fiber has a wide range of uses and can be woven into thin threads, thread ends and hemp ropes. It can also be woven into fiber layers when making paper or felt.
