글루타르알데히드 가교 조건에 따른 콜라겐 섬유의 방사성 및 역학적 특성 분석

Abstract

Collagen is a natural protein with excellent biocompatibility. Purified collagen isused in various medical and cosmetic products. Fibers made from collagen are particularlyused for medical purposes, but their mechanical properties are not good; therefore, manufacturingprocesses such as crosslinking and blending are being researched and developedto reinforce fibers and improve fiber spinnability. Particularly, in the crosslinking process,fiber properties can be manipulated and adjusted based on the crosslinking agent. In thisstudy, the spinnability and mechanical properties of the fibers were analyzed according tothe crosslinking concentration and crosslinking process time. Through this, the crosslinkedcollagen spinning conditions that can achieve a sufficient crosslinking effect with a minimumconcentration and process time were examined. The processing efficiency andmechanical properties of the collagen fibers were improved by optimizing the crosslinkingconditions.
