Method for preparing artificial ligament with high tensile durability, anti-fatigue, low creep and stress relaxation rate, artificial ligament prepared therefrom, and fiber collection platform by interfacial polyelectrolyte complexation spinning

A method for preparing an artificial ligament, comprising the following steps:

• (a) forming an artificial ligament fiber through interfacial polyelectrolyte complexation spinning (IPC spinning) process, wherein the artificial ligament fiber is formed by spinning on a fiber collection platform by the interfacial polyelectrolyte complexation spinning process using a positively charged poly(amino acids) polymer material and a negatively charged polysaccharide polymer material;
• (b) weaving the artificial ligament fiber using a twisted weaving method to form an artificial fiber bundle;
• (c) using a crosslinking agent to strengthen the artificial fiber bundle, thereby forming a strengthened artificial fiber bundle;
• and
• (d) creating a mineralization gradient on the strengthened artificial fiber bundle, and using a protein as a sheath for coating layer, thereby forming the artificial ligament with its fundamental characteristics and structure;
• wherein in step (a), the positively charged poly(amino acids) polymer material and the negatively charged polysaccharide polymer material are respectively in a form of positively charged droplets and negatively charged droplets, and the positively charged poly(amino acids) polymer material and the negatively charged polysaccharide polymer material are dropped on the fiber collection platform, and the artificial ligament fiber is fabricated by contact of the positively charged droplets and the negatively charged droplets through pulling upward.
