Composite spun fibers have been widely used in the medical field due to their diverse properties, as follows:
1. Surgical sutures: Some composite fibers such as polylactic acid hydroxyacetic acid copolymer (PLGA) are combined with natural polymer materials (such as collagen) to form sutures, which have both good mechanical properties of synthetic polymers and biocompatibility and degradability of natural polymers. After the wound heals, it can gradually be absorbed and decomposed by the human body without the need for stitches, reducing the patient's pain and risk of infection.
2. Medical dressings: Medical dressings made of composite spun fibers have good moisture absorption and breathability, which can effectively absorb wound exudate, keep the wound moist, and promote wound healing. For example, for the dressing compounded by alginate and polyester fiber, alginate can absorb a large amount of exudate to form gel, providing a wet healing environment for the wound, while polyester fiber enhances the strength and stability of the dressing. In addition, composite fiber dressings containing antibacterial ingredients such as silver ions, chitosan, etc. can also prevent bacterial growth and prevent wound infections.
3. Tissue engineering scaffolds: In the field of tissue engineering, composite spun fibers can be used to create three-dimensional porous scaffolds that provide support for cell growth, proliferation, and differentiation. For example, scaffolds prepared by composite spinning of polycaprolactone (PCL) and hydroxyapatite (HA) provide excellent mechanical and processing properties, while HA has biological activity and can promote the adhesion and growth of bone cells, making it suitable for bone tissue repair.
4. Artificial blood vessels: Composite spun fibers can be used to manufacture artificial blood vessels to meet the clinical demand for vascular substitutes. Artificial blood vessels made of a composite of polytetrafluoroethylene (PTFE) and polyurethane (PU) have good chemical stability and anticoagulant properties, while PTFE has good elasticity and mechanical properties, allowing the artificial blood vessels to simulate the structure and function of natural blood vessels, reduce the risk of blood clot formation, and improve vascular patency.
5. Protective clothing: Composite spun fibers can be endowed with multiple functions through special treatment or composite with functional materials. Protective clothing made of composite spun fibers containing antibacterial and antiviral components can effectively block the invasion of bacteria and viruses, protecting the safety of medical staff; Composite spun fiber protective clothing with anti-static properties can prevent static electricity from interfering with medical equipment and is suitable for special environments such as electronic operating rooms.
6. Sanitary products: In the medical field, composite spun fibers are also widely used in the production of sanitary products, such as masks, surgical caps, gloves, etc. For example, masks made by combining meltblown fabric and spunbond fabric have good filtering performance, effectively blocking droplets and particles, while spunbond fabric provides certain strength and comfort, ensuring the protective effect and user experience of the mask.
