| Abstract: | In emergencies, surgical operations and military conflicts, the human body may suffer from severe trauma resulting in massive bleeding. In order to effectively control bleeding and reduce the chance of wound infection, an elastic bandage with antibacterial hemostatic functions was developed. Polypropylene (PP) spunbonded elastic nonwovens were chosen as the base materials and treated with hydrophilic modification of polyvinyl alcohol (PVA) and grafting modification of chitosan (CH) to obtain PP-PVA-CH elastic nonwovens with both functions of antibacterial and hemostasis. The properties of the samples before and after modification were analyzed. The results show that PVA and CH were successfully loaded on the surface of nonwovens without affecting the main crystal structures. The maximum tensile breaking strength and elongation at break of PP-PVA-CH were 1.40 and 1.24 times higher than that of PP, and elastic recovery rate of PP-PVA-CH was 88%. Contact angle of the modified sample decreased effectively, and the diffusion areas of deionized water and synthetic blood were 13.0 and 12.9 times that of PP elastic nonwovens, respectively. Antibacterial rate of PP-PVA-CH elastic nonwovens against E.coli and S.aureus were found higher than 99.0%. |
