 Full text | Abstract: An approximate approach is presented to calculate and predict the specific stress of wool/spandex core-spun yarn, based on an idealised yarn structure model and Hearle’s yarn theory. The approximate model covers some major parameters from wool fiber, spandex and core-spun yarn. Comparing with experimental tensile (stress-strain) curves of core-spun yarn, we can see that the theoretical model can basically reflect the shape of wool/spandex core-spun yarn’s tensile curve and the model is useful for predicting the stress-strain behaviour of wool/spandex core-spun yarn at small extension. |
