摘　　要： 为了解决传统热模压过程中无纺织物受热不均匀的问题,文章通过对热模压加热结构和变温模具进行改进与理论分析,根据实际需要设计并选择合理可行的变温模具加热装置,即采用可控热风加热方式。采用ANSYS软件对变温模具进行热场分析,并仿真了变温模具的温度场状况。结果表明,采用可控热风加热方式,可以提高无纺织物的拱度,改善无纺织物的手感和柔软度;采用有限元分析,对确定和验证模具工艺参数具有指导性的作用。 To solve the problem of non-uniform heating of non-woven fabrics in traditional thermally compression molding process,this paper is intended to make theoretical analysis of the heating structure of thermally compression molding and vario-thermal mold. A reasonable and feasible vario-thermal mold was designed and selected according to actual needs,namely controllable hot-blast heating method.ANSYS software was adopted for thermal field analysis of vario-thermal mold,and simulating the temperature field of variothermal mold.The results show that the controllable hot-blast heating method helps enhance the camber of non-woven fabrics,and improve the hand feeling and softness of non-woven fabrics;finite element analysis is of instructional significance to determination and verification of the technological parameters of the mold.
