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. 用來(lái)測(cè)定輪胎簾線(xiàn)在精確溫度控制下的收縮情況。It has since been modified to enable similar tests to be carried out on 1" wide strips of fabric,經(jīng)過(guò)改良后已經(jīng)能夠被應(yīng)用于1寸寬的紡織品上做類(lèi)似的測(cè)試了。 as well as yarns, mono-filaments etc. 也包括紗線(xiàn)和單纖維等等。Samples under test are exposed to the controlled air.樣品被暴露于受控制的氣體中， Temperatures between two 10" wide heated platens,在兩個(gè)10寸寬的壓盤(pán)中控制溫度，shrinkage per cent is indicated on a scale.伸縮率可以在表盤(pán)上顯示 Residual shrinkage can be ascertained by removing the sample from the heated zoneallowing it to cool.剩余的收縮率可以在樣品取出冷卻后得到。 A.S.T.M. Designated No. D4974-89.

Temperature range is adjustable from ambient to 250°C.溫度在室溫250度間調(diào)節(jié)。
