Alginate Dressing Material: Transition from Seaweed to Medical Textile Material

Alginic acid is a polymer material extracted from brown algae, which has the characteristics of moisture absorption, moisture retention, and heavy metal ion adsorption. The fibres prepared with alginate as raw materials form gels through ion exchange after contact with body fluids. When they are made into non-woven fabrics and applied to wounds, they can absorb a large number of tissue exudates and provide a moist healing environment for the wounds. Stimulates skin tissue growth and accelerates wound healing. The spunlace nonwoven fabric prepared from alginate fibre has the functions of moisture absorption, moisturizing, detoxification, whitening, etc., and has special application value in mask materials.


1. Global alginate medical care supplies technology


Driven by technological innovation and entrepreneurial development, he is engaged in the research and development of marine biomedical materials and has made several important inventions in the field of functional medical dressings. Through research and development based on the application of marine biological materials such as alginic acid and chitosan in the medical and health field, several common and key technologies in the field of preparation, modification and application of marine biological materials have been solved. It has successfully developed advanced medical materials such as pharmaceutical-grade sodium alginate, alginate dressing material series products for wounds, and implanted embolic agents in the body, which has driven the technological transformation and industrial upgrading of the seaweed farming and seaweed extraction industries. Realize the green, environmental protection and sustainable development of seaweed processing and seaweed active substance extraction, modification and application.


2. Broad prospects for seaweed medical care supplies


Seaweed is an important marine biological resource and the main body of marine plants. After more than 50 years of development, China has become the world's largest producer of seaweed chemical products. The industrial chain of comprehensive utilization of biological products has generated huge commercial value. The annual sales of water-soluble colloids extracted from seaweeds generate more than 2 billion US dollars. Seaweed biological products have been widely used in functional food, marine medicine, papermaking, textiles, cosmetics, ecological fertilizers, environmental protection and other fields, and play an increasingly important role in economic and social development.


Facing the future, with the ageing of the population, the increase of trauma among young and middle-aged people, the increase of patients with difficult diseases and the development of high-tech, marine biomedical materials based on seaweed have broad application prospects in the field of the health industry. High-quality, multi-functional marine biomedical new materials developed and produced from high-quality marine resources have good biocompatibility, high hygroscopicity and biodegradability, and have no toxic or side effects on the human body. It is the preparation of functional medical care supplies. It is a high-quality raw material for medical hygiene materials such as dressings, masks, surgical sutures, hygroscopic products for women and children, and adult incontinence products.


The unique properties of alginate fibres processed from alginate extracted from brown algae have shown excellent use value in medical products such as functional medical care supplies dressings, hygiene materials, and facial masks. The alginate band-aid and medical dressing series products have high hygroscopicity and form a soft gel upon contact with wound exudate, providing an ideal moist environment. Clinical studies have proved that alginate medical dressings are safe, non-toxic, and have the characteristics of high moisture absorption, hemostasis, gel formation, and bacteriostasis. They can promote wound healing, reduce local pain, and reduce scar formation. They are suitable for treating wound exudate and local hemostasis. For wounds with moderate or severe exudates and lacunae, such as bedsores, diabetic foot ulcers, lower extremity veins, arterial ulcers, burn wounds in the donor site and refractory burn wounds, and anorectal anal fistula postoperative wound oozing, exudate, etc. have a good curative effect.
