经编弹性口罩耳带生产工艺研究

Ear-bands Production Technology for Warp Knitted Elastic Mask

随着新冠肺炎疫情的爆发和蔓延,口罩耳带的需求量随口罩需求量的增长而大幅增加,针对目前口罩耳带市场供不应求的现象,提出运用双针床经编机高效高质生产3 mm口罩圆带和5 mm口罩扁带的工艺。详细介绍3 mm口罩圆带和5 mm口罩扁带两种口罩耳带的技术要求、原料选择、编织设备、编织工艺、性能测试及大批量生产时的工艺优化。并在此基础上提出经编弹性口罩耳带编织工艺的优化,包括新工艺研发、双针床经编机卷布机构及预缩方式的改进。最后提出双针床经编机编织口罩耳带存在的问题,促进双针床经编机及口罩耳带的可持续发展。

With the 2019-nCoV outbreak and spreading,the demand of mask ear-bands increases with the increase of masks demand.In order to solve the shortage of mask ear-bands,this paper puts forward the technology of using double needle bar warp knitting machine to produce 3 mm round mask ear-bands and 5 mm flat mask ear-bands with high efficiency and high quality.It introduces in detail the technical requirements,raw material selection,knitting equipment,knitting process,performance test and process optimization in mass production of these two kinds of mask ear-bands.On this basis,the optimization of the knitting process of elastic mask ear-bands is proposed,including the development of new technology,the improvement of roll-up device and pre-shrinking method.Finally,the problems of knitting mask ear-bands when using double needle bar warp knitting machine are put forward to promote the sustainable development of double needle bar warp knitting machine and mask ear-bands.
