Polylactic Acid Fiber Preparation
Polylactic acid (PLA) fiber is a biodegradable polymer fiber derived from renewable plant resources. It is produced by fermenting natural starches such as corn or sugarcane to obtain lactic acid, which is then polymerized through condensation or ring-opening polymerization to form polylactic acid. Finally, the fibers are fabricated via melt spinning, solution spinning, or electrospinning. PLA fibers offer advantages including light weight, high strength, good moisture absorption, and biodegradability. Moreover, through fiber morphology, surface modification, and composite material techniques, PLA fibers can achieve functional and biomimetic applications. In the field of biomimetic materials, PLA fibers can be processed into nanofiber scaffolds, microfiber meshes, layered or aligned fibers, biodegradable medical dressings, and functional composite fibers for applications in tissue engineering, drug delivery, smart textiles, and cartilage and tendon regeneration.

Frequently Asked Questions
What is PLA fiber?
PLA fiber (Polylactic Acid fiber) is a biodegradable, bio-based polymer fiber derived from renewable resources such as corn starch or sugarcane. In biomedical and biomimetic applications, PLA fiber is widely used to create tissue engineering scaffolds, drug delivery carriers, and degradable medical materials due to its excellent biocompatibility, tunable mechanical properties, and controllable degradation rate. It is ideal for simulating extracellular matrix structures and supporting cell growth in regenerative medicine.
How to make PLA fiber?
PLA fiber can be produced using melt spinning, solution spinning, or electrospinning techniques, depending on the desired fiber diameter and structure. In biomimetic and biomedical applications, electrospinning is commonly used to create nanofiber scaffolds that mimic the extracellular matrix. Process parameters such as polymer molecular weight, spinning temperature, and solvent system are carefully controlled to achieve fibers with high uniformity, adjustable porosity, and optimal mechanical strength for tissue engineering and drug delivery applications.
What are the characteristics of PLA fiber?
PLA fiber is biodegradable, biocompatible, and derived from renewable resources, making it ideal for medical and biomimetic materials. Key characteristics include adjustable mechanical properties, controllable degradation rate, high surface area (especially in nanofibers), and compatibility with functional modifications such as drug loading, antibacterial treatment, or conductivity enhancement. These properties enable PLA fiber to support tissue scaffolds, drug delivery systems, and advanced biomimetic materials.
How can PLA fibers be modified?
Yes, PLA fibers can undergo chemical or physical modifications to improve hydrophilicity, mechanical strength, or bioactivity.
