Comparative Study Between Exhaust Method and Cold-pad Batch (CPB) Method for Dyeing 100% Cotton Fabric

Abstract

Dyeing is the operation of colorings or colors on cloth accouterments similar as filaments, yarns, and fabrics with the thing of achieving color with asked colorfastness. Dyeing is typically done in a special result containing colorings and particular chemical material. Color motes are fixed to the fiber by immersion, prolixity, or relating with temperature and time being crucial controlling factors. The bond between color patch and fiber may be strong or weak, depending on the color used. This paper shows the usual two methods of dying which are exhaust dyeing and CPB dying with their process difference. It also presents the results of different tests of the dyed fabric from these two dying methods. In this thesis, we use one type of single jersey fabric of the same construction for both dying processes. The dyed fabrics have been gone through different types of tests in the physical lab like; dimensional stability test, color fastness to- washing, rubbing, light, water, perspiration, ICI pilling resistance test. This thesis analyses the end lab results and presents if there is any difference in the dyed fabric to evaluate the overall better process for this type of single jersey.
