Influence of Dyeing Techniques on Strength-Abrasion of DCT -Dyed DMDHEU-Finished Cotton Fabric

Abstract

<span style="font-size:11.0pt;line-height:115%; font-family:" calibri","sans-serif";mso-ascii-theme-font:minor-latin;mso-fareast-font-family:="" calibri;mso-fareast-theme-font:minor-latin;mso-hansi-theme-font:minor-latin;="" mso-bidi-font-family:arial;mso-ansi-language:en-us;mso-fareast-language:en-us;="" mso-bidi-language:ar-sa"="">Bleached mercerized cotton sheeting (200g/m²) samples, dyed with a dichlorotriazinyl dye, CI Reactive Blue 4, by exhaust (Exh) and pad batch (PB) techniques, were subjected to catalyst control (20g/1 M_gCl₂.6H₂O) treatment and DMDHEU finishing by pad-dry-cure treatment and evaluated for resilience and strength-abrasion properties. The samples dyed by Exh technique suffer greater loss in strength-abrasion properties than the corresponding samples dyed by PB technique. This is corroborated by the higher cuprammonium fluidity values of the samples blank dyed using Exh technique and subjected to catalyst control treatment as well as by the greater surface damage observed on scanning electron microscopic examination of samples dyed by the Exh technique.</span>
