In the area of tissue engineering, polyester felt is being explored as a scaffold material for tissue regeneration. The porous structure of polyester felt provides an ideal environment for cells to adhere, grow, and differentiate. Scientists are using polyester felt scaffolds to promote the regeneration of damaged tissues such as cartilage, bone, and skin. For example, in the treatment of large – scale skin wounds, polyester felt – based scaffolds can be seeded with skin cells and applied to the wound site. The scaffold supports the growth of new skin tissue, accelerating the healing process and reducing the risk of scarring. Moreover, the biodegradable properties of certain types of polyester felt allow the scaffold to gradually break down as the new tissue forms, eliminating the need for a secondary surgical procedure to remove the scaffold.​

Polyester felt also shows great potential in drug delivery systems. By incorporating drugs into polyester felt matrices, researchers can create controlled – release drug delivery devices. These devices can be designed to release drugs at a specific rate over an extended period, ensuring a consistent and targeted drug supply to the affected area. For instance, in the treatment of chronic diseases such as diabetes or cancer, polyester felt – based drug delivery patches can be applied to the skin, providing a convenient and non – invasive alternative to traditional injection – based therapies. The ability to control the release of drugs precisely using polyester felt not only improves the efficacy of the treatment but also reduces the side effects associated with systemic drug administration.​

In the field of minimally invasive surgery, polyester felt is being used to create innovative surgical devices and implants. Its flexibility and strength make it suitable for manufacturing stents, catheters, and other surgical instruments. Polyester felt – coated stents, for example, can be inserted into blood vessels to keep them open and improve blood flow. The coating on the stent reduces the risk of blood clots and inflammation, enhancing the long – term success of the procedure. Additionally, polyester felt implants can be used to repair damaged organs or tissues, providing structural support and promoting tissue integration.​

The use of polyester felt in medical applications is still in its early stages, but the potential for growth and innovation is immense. As researchers continue to explore the properties and capabilities of polyester felt, new and improved medical therapies are likely to emerge. With strict regulatory requirements and a focus on patient safety, the development of polyester felt – based medical products will need to undergo extensive testing and validation. However, if successful, polyester felt could revolutionize the medical field, offering new hope for patients suffering from a variety of diseases and injuries.
