Study of Different Washing Techniques on 100% Cotton Based Denim Fabric and Dyed Twill Weave Cotton Fabric
(University of Management and Technolog, 2018) Abdullah, Ahmad
Denim washing is not such an old thing that is not known to us. It is done to get proper aesthetic look of the fabric. This research consists of two parts: the first one is the washing of denim fabric with enzyme, bio-polish, enzyme and stone, resin dip and resin spray. In the second part, the 100% cotton based twill fabric is dyed with reactive, direct and pigment dyes and then their enzymatic, bio-polish and enzyme and stone wash is done. For this purpose, the leg tubes of different sizes of denim and twill fabric are made. The different tests are performed on the test specimens like dimensional change after washing, pilling resistance test by ASTM-D 4970, tensile Strength of the fabric by ISO-13934-2:2000, tear Strength of fabrics by ISO-13937-2:2000, shade variation after different washing methods, scanning electron microscope for washed fabric (SEM images) and absorbency of textiles by AATCC test method 79 (2010) and the results are compared with respect to their different techniques.
