Abstract

The aim of this research is to investigate the shrinkage properties of cotton polyester spandex denim fabrics of different fiber content. Cotton fabrics with spandex have a tendency to shrink when it comes in contact of water. Cotton spandex shrinks more when it comes in contact of hot water. Cotton is swelled up in water; thereby increase the width of fibers, as a result there is the decrease of length. If the cotton composition with spandex increases, the shrinkage property of fabric also increases. The higher the percentage of spandex content in a fabric is, the higher the value of shrinkage is. On the other hand, polyester does not shrink when it comes in contact of water, as manmade polyester fiber does not swell up in water. Three specimen of cotton polyester spandex denim fabrics of different fiber content were used in this research. Finished fabrics were collected from fabric mills for conducting the required shrinkage test with the standard specified by AATCC Test Method 135. This research is practice based and the discoveries are advantageous to the textile professionals. This research proved that the properties of shrinkage depends on the fiber content of cotton polyester spandex denim fabrics and it showed a suitable way for the scholars to further study in this field.
