Abstract:

In this study, air permeability of woven fabrics is predicted from the parameters of weave structures. Air permeability is an important property of fabrics and has a decisive influence on the utilisation of fabric for some technical and clothing applications. There is no doubt that predetermination of the air permeability in woven fabric is vital, and modelling the effective parameters shows the role of the factors as well as the prediction of the property. To promote the design of woven fabrics, we can define the crossing over firmness factor (CFF) and floating yarn factor (FYF) as the parameters of the weave structures for predicting air permeability values. All the parameters are related to air permeability. Multiple regression equations of air permeability are derived from those parameters of weave structures and the values predicted almost exactly agree with the values measured from the FAST system.
