Alginate Fibers and Wound Dressings
Comprehensive resource on the science and research behind alginate fibers, along with their many functional applications in different fields
Alginate Fibers and Wound Dressings: Seaweed Derived Natural Therapy offers a general introduction to the sources of alginate and the production methods for alginate fibers and wound dressings, in addition to the novel properties and applications of these functional materials in wound management. Taking into consideration of the latest results of clinical researches conducted around the world, this book summarizes the unique properties of alginate wound dressings, including their ‘gel blocking’ properties and the ability to promote wound healing, facilitate haemostasis, reduce pain, suppress bacteria growth, and lower treatment cost in the treatment of a wide range of wounds, including leg ulcers, burn wounds, pressure sores, surgical wounds, and many other types of wounds with high levels of exudates.
Sample topics covered in Alginate Fibers and Wound Dressings include:
- Why alginate fibers can be used as a carrier to deliver zinc, copper, silver, and other bioactive metal ions
- How alginate wound dressings can help maintain a physiologically moist microenvironment that promotes healing and the formation of granulation tissue
- Unique properties of alginate fibers that are highly useful for functional textile materials and medical textile products, such as gel forming properties when in contact with body fluid
- Other excellent performance characteristics of alginate fibers, such as haemostatic, antimicrobial, skin whitening, and many other unique bioactivities
Providing comprehensive coverage of the subject, Alginate Fibers and Wound Dressings is an essential resource for students, researchers, and professionals involved in professions and programs of study that intersect with the subject.
