A method for preparing a polyglutamic acid (&#x3b3;-PGA) fiber having antibacterial and water absorption properties is provided. The method includes providing a &#x3b3;-PGA fiber and immersing it in a sodium hypochlorite solution. A relation exists between an immersing time T of the &#x3b3;-PGA fiber and a concentration X of the sodium hypochlorite solution as shown in the formula below:10.2&#x2266;(64.5550)&#x2266;15.2,wherein X is 0.006-0.4 wt %.

Method for preparing high water-absorption and anti-bacterial gamma polyglutamic acid fibers

A water-insoluble polyglutamic acid (PGA) fiber and a preparation method thereof are provided. In the preparation method, the PGA is cross-linked by a cross-linking agent and then passes through a spinning nozzle to form PGA fibers. Therefore, the highly water-absorbing PGA, which cannot be spun by conventional methods, can be spun to form PGA fibers and maintain the high water-absorption ability.
