Preparation Process Optimization and Performance Evaluation of Carex Meyeriana Kunth Flocs
In this paper,9 kinds of carex meyeriana kunth/ES fiber composite flocs were prepared by hot air bonding process with carex meyeriana kunth and ES fiber as raw materials.The air permeability,moisture perme-ability,warmth retention and compression properties of 9 kinds of flocs were evaluated by orthogonal optimization and range analysis.The results showed that when the mixing ratio of carex meyeriana kunth/ES fiber was 8∶2,the hot bonding temperature was 145℃,and the hot bonding time was 15 min,the comprehensive performance of the composite flocs was the best.The air permeability of the composite flocs prepared under this condition was 1321.71 mm/s,the moisture permeability was 157.887 g/m2·h,the thermal conductivity was 0.0405 KJ/m·K·h,and the compression recovery rate was 78.21%.The study provided reference and basis for the applica-tion of carex meyeriana kunth in floccules.
