Green technology in textile processing: Part II - Bleaching of polyester/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:="" "times="" new="" roman";mso-fareast-theme-font:minor-fareast;mso-hansi-theme-font:="" minor-latin;mso-bidi-font-family:"times="" roman";mso-ansi-language:en-us;="" mso-fareast-language:en-us;mso-bidi-language:ar-sa"="">Two new formulations have been prepared for bleaching of polyester/cotton (48:52) dhoti fabrics and the results of bleaching with these formulations have been compared with those of the conventional process. The new formulations result in significant savings in steam, electricity and water. A total saving of 10.67% in the cost of polyester/cotton dhoti preparation has been reported. These formulations are also eco-friendly as they avoid use of toxic bleaching agents, require lesser concentration of chemicals and generate reduced load of effluent. Biological oxygen demand and chemical oxygen demand lower by 38% and 35% respectively have been reported.</span>
