模线样板技术中聚酯薄膜变形研究

The Study on Polyester Film Deformation in the Lofting-template Technology

针对利用聚酯薄膜绘制的模线数据与样板不一致的现象,提出了可能的三个原因:绘图机数据出现了偏差;激光切割机数据出现了偏差;聚酯薄膜变形。通过对比实验,确定聚酯薄膜变形是导致模线数据与样板不一致的主要原因。进一步利用控制变量法,分别对聚酯薄膜进行温湿度实验和存放状态实验,为不同分组的聚酯薄膜设置不同的温度、湿度、放置状态,发现温湿度是导致聚酯薄膜变形因素,同时与其放置状态也有一定的关系。

Aiming at the phenomenon that the data of the mould-line drawn from the polyester film are not consistent with the model, this paper presents three possible reasons. There may be a deviation from the data of the drawing machine. The data of laser cutting machine may has a deviation, or it is because of the deformation of polyester film. By experiments, we confirmed that the deformation of the polyester film is the main reason of the inconsistent data and the model.Furthermore, Experiments on temperature and humidity of the polyester film and the storage state of the film were carried out. This paper set different temperature, humidity, placed state in control variable method for polyester film from different groups, and find that temperature and humidity are the main factors leading to the deformation of polyester film.It also has a certain relationship with its position.
