Surface modification of acid activated polyamide fiber by immobilizing collagen
Collagen was immobilized onto moderate acid activated polyamide fibers with glutaraldehyde (cross-linking agent) aimed to improve its sanitary property.The immobilization of collagen onto polyamide fiber was estimated by dyeing collagen modified fabrics with a cationic brilliant red 5GN,and determining the dyeing properties of the dyed fabrics.The modification also confirmed technically by Differential scanning calorimetry (DSC),Scanning electron microscopy (SEM) and Atomic force microscope (AFM).Cationic dyeing showed brighter and more even dyeing properties of the collagen modified fabrics compared to the non-treated fabrics.From DSC results,it was found that the thermo-stability of the non-treated and collagen modified fabrics changed a lot.The morphology of different samples from SEM and AFM also approved the immobilization of collagen.The moisture absorption and hydrophilicity of the fabrics after collagen immobilization improved compared to the non-treated fabrics.
