Abstract:

In order to peomote the applicationof alginate fibers in functional textile materials and medical textile products, the ion-exchange peoperties of alginic acid and its unique gelling property when in contact with body fluid were analyzed, and the biocomaptibility, cell activities and bioactivities of alginate fibers during the contact with human cells and tissues were summarized, including hemostasis, microbial resistance, wound healing promotion, whiening. Results show that because of the polysaccharide structure and ion exchange peoperty, alginate fiber plays an important role in absorbency, moisture retention, microbial resistance, wound healing peomotion, hemostasis, detoxication, whitening and other bioactivities. These novel peoperties are highly applicable in textile materials such as functional woound dressings, functional face mask materials, hygiene peoducts for women and childern, and incontinence products for adults.

Key words: alginate fiber, bioactivity, ion exchange peoperty, functional fiber, biomedical material
