POLİESTER MONOFİLAMENTTEN ÜRETİLMİŞ BİYOMEDİKAL TEKSTİL İÇİN YÜZEY İŞLEMİ

Foreign Body Reaction is a critical issue to be addressed when polyethylene terephthalate textile implants are considered in the medical field treat pathologies involving hernia repair, or heart valve replacement. The natural porosity of materials tends induce exaggerated tissue ingrowth which may prevent from remaining flexible. One hypothesized way limit process increase material surface roughness. Supercritical jet particle projection technique that provides enough velocity particles order generate plastic deformation on impacted surface. aim this study investigate influence micro laden supercritical nitrogen parameters like static pressure, standoff distance and size roughness fabric surfaces. Results bring out projected by craters monofilament as well fabric, allowing topographical modifications at yarn scale. Thus, treatment increased 0.78 μm 1.22 μm. Regarding strength material, it only slightly modified with process, tenacity yarns decreases 10%. In work, revealed obtained structures tend adhesion slow down proliferation human fibroblasts. results work show possible create using technology.
