Abstract: High heat preservation modified down using zirconium oxychloride/down fiber as raw material were prepared by phosphorylation of sodium tripolyphosphate.The thermal insulation property,reaction mechanism,surface morphology and thermal property of modified down were characterized and analyzed by SEM,EDX,flat plate warmth retaining tester,filling power and TG.The results indicated that zirconium oxychloride was successfully grafted onto the down fiber,compared to raw down,CLO value significantly increased by 35.38%,the thermal resistance significantly increased by 35.43%,the thermal insulation rate was 80.95%.The thermal property was improved,the residual mass was 30.06%.It illustrated that zirconium oxychloride improved the thermal insulation property of traditional down fiber and it will be warmer,more economical and multifunctional.
