在准确温度下测量轮胎帘线、纱线的热收缩情况。
This machine was originally designed in conjunction with the Tyre Technical Division of Dunlop Rubber Co. Ltd.,to determine the shrinkage of tyre cord yarns at closely controlled temperatures. 用来测定轮胎帘线在精确温度控制下的收缩情况。It has since been modified to enable similar tests to be carried out on 1" wide strips of fabric,经过改良后已经能够被应用于1寸宽的纺织品上做类似的测试了。 as well as yarns, mono-filaments etc. 也包括纱线和单纤维等等。Samples under test are exposed to the controlled air.样品被暴露于受控制的气体中， Temperatures between two 10" wide heated platens,在两个10寸宽的压盘中控制温度，shrinkage per cent is indicated on a scale.伸缩率可以在表盘上显示 Residual shrinkage can be ascertained by removing the sample from the heated zoneallowing it to cool.剩余的收缩率可以在样品取出冷却后得到。 A.S.T.M. Designated No. D4974-89.
Temperature range is adjustable from ambient to 250°C.温度在室温250度间调节。
