Optimization of Residual Shrinkage Control of 100% Cotton Woven Fabric Through Sanforization
Received Date: August 19, 2020; Published Date: September 10, 2020
Textile fabrics (woven or knitted) are subjected to strain both lengthwise and widthwise during fabric manufacturing. This strain is released while washing the fabric under relaxed conditions, resulting in a reduction in length and/or width of the fabric which is called shrinkage. Apparel made of such fabrics suffers shrinkage after washing and go out of fit. In order to eliminate or minimize such undesirable alternation, the fabric need to be stabilized dimension-ally. Commercially cotton woven fabric are given an anti-shrinkage finish branded as “Sanforized”. This study focused on sanforization of 100% cotton twill fabric. The effects of three variables namely damping percentage, machine speed, overfeed percentage on shrinkage imparted in the finished fabrics were investigated. Shrinkage imparted to the fabrics was increased with increasing in the variables specially overfeed% and damping. The increase in machine speed imparted less shrinkage.
