Antimicrobial Peptides In The Antibacterial Finishing Of Textile Applications

The antibacterial finish of wool fabric by adjusted pH with the NaAC/HAC buffer solution and immobilized antibacterial peptide was undergone.Major parameters in Soaking-Rolling over antibacterial peptide and immobilizing process were discussed in detail. The optimum conditions were defined as follows. Compared with Soaking-Rolling over can know that immobilized antibacterial peptide has the better antibacterial effect. The best handicraft is 0.2% glutaric dialdehyde,pH value 7.0,immobilizing for 6h. On this case,wool fabric had good bacterial resistance to Golden yellow staphylococcus and Backwoods coli.Selects the gelatin and the arabic gum as the wall material, the antibacterial peptide as the core material, the Span 80 and Tween 80 as the emulsifier, uses the compound condensation law preparation antibacterial to peptide microcapsule. And inspected the agitation rotational speed which affect the microcapsule particle size. The experiment indicated that when the agitation rotational speed is 1000r/min the microcapsule's grain-size distribution is the best. Then added the microcapsule to the sea alginic acid sodium solution and blows the membrane, and used the agar-agar plate diffusion process (according to GB/T20944.1-2007 textile antibacterial performance appraisal) to carry on the appraisal to its antibacterial performance. The experimental result indicated that the antibacterial peptide microcapsule has good antibacterial.The major of the research paper is on the antimicrobial finishing of cotton fabrics using antimicrobial peptides, after and determines reorganizes, the fabric to the golden yellow staphylococcus and backwoods coli's antibacterial, after the appraisal reorganizes, the fabric antibacterial performance quality, thus determines the antibacterial peptide reorganization woven cottons the best union way and the best technological conditions measuring First, experiment determines the activity of bacteria and antimicrobial peptides in order to ensure the feasibility of the experiment. And Then carries on the esterification response through the woven cottons and the antibacterial peptide to respond and with three gathers the chlorine cyanogen to carry on crossing linking, after its reorganization fabric antibacterial performance. Owing to micro-cyanuric chloride dissolved in water, antimicrobial peptides with less cross-linked cotton fabric, acetone can chosen to help dissolving, but it has some toxicity, and esterification reaction is simple, experiments determines the antimicrobial finishing for better methods is esterification reaction. And then control the different reaction conditions, choose a suitable temperature, pH and the amount of antimicrobial peptides, through testing the anti-bacterial fabric performance, evaluate the anti-bacterial effects to determine the optimal experimental finishing program. The experimental results show at room temperature and pH=5,the fabric has good anti-bacterial properties and can maintain the origin performance.
