印染行业热定形过程与定形机装备发展趋势

Development Trend of Heat Setting Process and Equipment in Printing and Dyeing Industry

针对印染行业热定形的发展现状和关键技术问题,文中从印染热定形过程和热定形装备两个方面,分析了热定形技术和热定形装备的发展趋势。阐述了目前针对热定形过程的研究,主要集中在传热传质模型、工艺参数、关键变量智能化控制和节能降耗4个方面,整个热定形过程会向着提高品质、增加产能、节能减排的方向发展。指出作为热定形过程的主要装备,定形机的发展会推动热定形技术的发展,定形技术的发展也会推动热定形机的发展;目前双层热定形机占地面积小、能量利用率高、产品质量好,是未来热定形机的发展趋势。

In view of the development status and key technical problems of heat setting technology in printing and dyeing industry,this paper analyzes the development trend of heat setting technology and equipment from two aspects of printing and dyeing heat setting process and heat setting equipment.At present,the research on heat setting process mainly focuses on four aspects:heat and mass transfer model,process parameters,intelligent control of key variables and energy saving and consumption reduction.The whole heat setting process will develop in the direction of improving quality,increasing production capacity and energy saving and emission reduction.As the main equipment of heat setting process,the development of heat setting machine will promote the development of heat setting technology,and the development of setting technology will also promote the development of heat setting machine.At present,the double-layer heat setting machine occupies a small area,and has high energy utilization rate and good product quality,which is the development trend of the future heat setting machine.
