What is a common feature of non-woven fiber meshes?

Non-woven fiber meshes are characterized by their construction method, which involves bonding fibers together through various techniques such as chemical, thermal, or mechanical means rather than by weaving. This results in a mesh with a random fiber arrangement, which contributes to the unique properties of non-woven materials.

The random arrangement of fibers allows for excellent fluid permeability, making these meshes suitable for applications in tissue engineering, wound dressings, and filtration systems. Furthermore, the non-woven structure can enhance the attachment and growth of cells in biological applications, as the fibers create a supportive matrix that mimics the extracellular environment.

In contrast, traditional woven fabrics are made by interlacing threads, which would not apply to non-woven mesh structures. High tensile strength can vary among non-woven materials and is not a defining characteristic, as some non-woven products may prioritize flexibility and softness over strength. Similarly, braiding involves a specific method of constructing materials that does not pertain to the random bonding associated with non-woven fibers. Thus, the defining feature of non-woven fiber meshes lies in their random fiber arrangements.
