低损耗纬编成形女士背心的结构设计与建模

Structural design and modeling of low-waste weft knitting fully fashioned female vests

为降低纬编成形背心织造工序的原料损耗和生产能耗,以女士紧身短背心为开发对象,进行结构建模与工艺实践。首先将传统纬编成形背心纵向织造的宽肩带转化为横向织造的矩形肩带,其次对背心进行功能分区,设计不同性能的无缝组织。然后通过虚拟仿真,参数可视化建模调整分区结构与数值,实际织造后对比结构转化前后的损耗。结果表明:通过对纬编成形背心的结构转化并进行功能分区、可视化建模,进行工艺参数的调节,实现了低损耗与高效率兼顾的纬编成形女士紧身短背心的生产,为纬编成形服装结构转化与节能产品开发提供参考。

In order to reduce the waste of raw materials and production energy consumption in producing weft-knit vests,the female tight-fitting short vest was taken as the object for research and development,involving structural modeling and processing experiment.The traditional weft knitting fully fashioned vest was produced longitudinally with shoulder width transformed into transverse rectangular shoulder width,whilst the vest was divided into regions according to function specifications which were fabricated with different seamless structures to achieve the desired properties.Through virtual simulation and parameter visualization,the values for the partition structures were able to be readjusted.Material waste comparison was carried out between the new and conventional methods.The results show that by transforming the structure of the weft knitting fully fashioned vest and performing functional partitioning,visual modeling and adjusting the process parameters,the production of weft knitting fully fashioned female vests with low material waste and high efficiency are achieved,which offers reference ideas for transformation and energy-saving product development of similar products.
