The use of antimicrobial sutures can effectively reduce the risk of infection in surgical patients. Surgical sutures were prepared by knitting polylactic acid fibers using a biomedical knitting machine, and drug-loaded slow-release microspheres were prepared by the emulsification-solvent evaporation method. Finally, dopamine was utilized to construct a secondary reaction platform for the sutures, which led to the successful loading of drug-loaded microspheres onto the surface of the sutures with minimal changes in diameter and weight. The suture exhibited a knotless strength of 32.88 N and knotting strength of 32.34 N, respectively. The initial release of the drug-loaded microspheres of each specification was modest, and the release rate of the microspheres of each specification exhibited variability, thus achieving the desired control of the release. In addition, the finishing sutures demonstrated effective antimicrobial properties against <i>Escherichia coli</i> (<i>E. coli</i>) and <i>Staphylococcus aureus</i> (<i>S. aureus</i>). The drug release pattern of the suture fits well with the Higuchi equation, and the drug release cycle can be up to about 17 d. Consequently, the microsphere-loaded surgical suture material prepared in this experiment exhibits favorable mechanical properties, along with remarkable antimicrobial properties.

The sensing strain range of most flexible strain sensors is less than its tensile range, and it is easy to exceed its sensing strain range during use, resulting in unstable performance and failure of the sensor. An effective-strain-range-controllable and wear-resistant yarn strain sensor was developed with a core-sheath braided structure with the sensing yarn as the core and the braided yarn as the shell. This design strain allows for control over the effective strain range by adjusting the core sensing yarn’s pre-stretch ratio and the outer braided layer’s structure. This prevents damage to the conductive network and sensor failure caused by excessive stretching during use. The sensitivity, linear sensing range, and hysteresis of the braided strain sensors are effectively adjusted by changing the braiding yarns’ braiding angle and the sensing yarn’s pre-stretch ratio. Additionally, the sensors’ appearance and texture can be customized by changing the colour and material of the braiding yarns, allowing these sensors to integrate seamlessly with the garment and enhance their aesthetics. Furthermore, when combined with elastic fabric bands, these sensors can be attached to various parts of the human body to monitor physiological information, such as respiration and movement. The braided structure design presents a versatile strategy that could be applied to other types of strain sensors, achieving stability, durability, and aesthetics simultaneously.</p></div>","PeriodicalId":557,"journal":{"name":"Fibers and Polymers","volume":"26 1","pages":"433 - 446"},"PeriodicalIF":2.2,"publicationDate":"2024-12-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142995424","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The results reveal that by increasing the length of spacer yarns, the stress relaxation of the fabric decreases, while the maximum energy absorption efficiency increases.
