电脑横机编织三维全成形口罩结构建模与工艺实践

为探究用电脑横编机开发全成形针织产品的可能性,以针织三维全成形口罩为开发对象,进行结构建模与工艺实践。首先对人体面部尺寸进行测量,以此确定全成形口罩的二维纸样;然后结合全成形口罩规格尺寸进行工艺计算,以四针床电脑横编机和SDS-ONE APEX3系统为开发工具,分别建立针织三维全成形口罩的口罩主体、过滤垫片口袋开口、挂耳带部位的结构模型。结果表明:通过对口罩的规格设计并建立结构模型,同时结合工艺参数的调节并优化其生产技术,可实现兼具美观性与舒适性三维全成形口罩的快速生产,结合功能性原料可开发高附加值的口罩产品。

Structural modeling and process practice of three-dimensional fully fashioned face masks woven by computerized flat knitting machine

In order to explore deeply the possibility of computerized flat knitting machines for creating fully fashioned knitted products, a knitted three-dimensional(3-D) fully fashioned face mask was chosen as the development object for structural modeling and process practicing in this research. The face size was firstly measured to determine the two-dimensional pattern for the mask. Then the process calculation was carried out based on the mask specifications, the four-needle bed computerized flat knitting machine and the SDS-ONE APEX3 system were set up and used as development tools to establish the structural model of the knitting mask body, pocket opening for filter gasket, and ear belts of the mask. Results show that the rapid production of 3-D fully fashioned masks with both aesthetics and comfort are achieved by establishing the structural model for the specified design of the mask, and by combining the adjustment of the process parameters to optimize its production technology. In addition, high value-added mask products could be effectively developed when using functional raw materials.
