Abstract

Creasing is a very complex phenomenon dealing with combined action of several forces like bending, flexing, tensile etc. It an aesthetic property and has direct bearing with the constituent yarn/fibers of which it is composed of and could also be direction dependent. Application of finishes is an important part of any textile manufacturing but is likely to affect the crease recovery property as it tends to fill up the empty spaces inside the fabric matrix. Nevertheless finishes have to be applied to the fabrics to improve their performance/feel/any related property. In that case it becomes necessary to study, not only its influence on the recovery behavior but also on other properties like bending, draping, permeability or whichever property is expected to be affected. Just as recovery behavior of yarns is important and is time dependent same is true for fabrics. This work reports the crease recovery of fabrics in their dry state taken at different time intervals. The greater is the recovery; greater is its resistance to crease formation. Design-expert® software has been used to develop a model to predict crease recovery angle (CRA) for different recovery times and fabric weight per unit area. Significant model could be developed with these variables and equations developed can be used to obtain the recovery angles at desired time interval (0 to 60 seconds), GSM (67 to 246) and for warp/weft.
