With the continuous improvement of medical health standards, the production process and raw material selection of medical nonwoven fabrics have been continuously optimized. The functionality, safety, and process compatibility of the raw materials have become the key considerations in industry production. The differences in physical and chemical properties of different fiber raw materials determine the classification of medical non-woven fabrics and the detailed directions of application scenarios.

Polypropylene, as the mainstream base material for medical nonwoven fabrics, has characteristics such as high purity, strong chemical stability, and good biocompatibility. It does not react with body fluids or common disinfectants, and can withstand various sterilization treatment methods. After being formed by the melt-blown spinning process, its fiber web structure combines both breathability and particulate matter filtration efficiency, and is widely used in the manufacturing of disposable protective products such as medical masks, surgical gowns, and isolation suits.

For medical products that come into direct contact with the skin or wounds, natural and recycled fibers such as viscose fibers and pure cotton fibers are preferred due to their moisture absorption, softness, and low allergenicity. These fibers have a gentle touch and do not cause irritation to damaged skin, and are suitable for medical dressings, care pads, sterile wiping cloths, and care bed sheets. In practice, to balance comfort and mechanical strength, blending processes are often used, combining natural fibers with synthetic fibers to enhance the durability and dimensional stability of the products.

In summary, the polypropylene system and the skin-friendly fiber system form a clear functional division in the field of medical non-woven fabrics. The former excels in protection and stability, while the latter has advantages in comfort and biological affinity. Together, they support the diverse application patterns of medical non-woven fabrics.
