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 properties of fabrics also increase. The higher the percentage of spandex content in a fabric is, the higher the values of shrinkage are. On the other hand, polyester does not shrink when it comes in contact of water, as manmade polyester fibers do not swell up in water. Three nomenclature of cotton poly spandex denim fabrics of different composition were used in this research and to do the required tests. Finished fabrics were collected from fabric mill to do the required tests in AATCC Test Method 135. This experiment proved that, the properties of shrinkage depends on the composition of cotton, polyester and spandex and it created a suitable way for the scholars to further study in this field.
