Abstract
The present disclosure provides an antimicrobial alginate fiber, a method for manufacturing an antimicrobial alginate fiber dressing thereof, and an application thereof. When the cationic polymer polyhexamethylene guanide salt is mixed with the anionic polymer alginate, the antimicrobial activity of the guanide salt is quickly passivated. The present disclosure achieves a lower content of polyhexamethylene guanide salt in an alginate dressing with good long-term antimicrobial activities. The polyhexamethylene guanide salt has a low dissolution rate, and significantly reduces a potential risk of carcinogenicity, mutagenicity and reproductive toxicity.
Claims8
An antimicrobial alginate fiber, comprising a molecular structure as shown in formula (1):
- wherein, X is equal to 10 to 40, n is equal to 10 to 40, and A is anyone of hydrochloric acid, phosphoric acid, propionic acid, and gluconic acid.
An application of an antimicrobial alginate fiber dressing, comprising:
- processing the antimicrobial alginate fiber by combing, laying, and needle-punching, to form alginate nonwoven fabrics;
- or
- processing the antimicrobial alginate fiber by weaving, to form alginate gauze;
- and
- processing the alginate nonwoven fabrics or the alginate gauze by cutting, packaging, and sterilizing, to form the antimicrobial alginate fiber dressing, and the antimicrobial alginate fiber dressing is applied to acute and chronic wound care;
- wherein the antimicrobial alginate fiber comprises a molecular structure as shown in formula (1):
- X is equal to 10 to 40, n is equal to 10 to 40, and A is anyone of hydrochloric acid, phosphoric acid, propionic acid, and gluconic acid.
