Alginate Fiber Preparation
Alginate fibers are biofunctional fibrous materials derived from natural polysaccharide polymers—alginates—through a wet spinning process. Alginates are primarily extracted from the cell walls of brown algae (Phaeophyceae, such as kelp and giant kelp) and are linear, anionic polysaccharides. Due to their unique ionic crosslinking properties, excellent biocompatibility, high hygroscopicity, and biodegradability, alginate fibers have found broad applications in modern medical, bioengineering, and functional textile fields. As a professional supplier of polymer chemicals and monomers, BOC Sciences is dedicated to providing comprehensive alginate fiber preparation and development services to research institutions, development enterprises, and industrial manufacturers. Our services cover the full process—from raw material selection, fiber design, and functional modification to laboratory-scale preparation and industrial production—helping clients accelerate the translation from proof-of-concept to mass production. Whether for tissue engineering scaffolds, drug-controlled release carriers, or biodegradable textile materials, we offer targeted solutions to meet diverse research and production needs.
