PROCESS FOR LEVEL DYEING OF 100% COTTON KNIT FABRICS WITH REACTIVE DYE (Pages : 1 - 8)

The research was carried out at Hamza Textile Mills Ltd.of Gazipur in 2007. A beige color is selected to dye in a modern knit-dyeing machine (jet type) with the capacity of 500kg; maximum load of 440kg with 88% load. Three batches are dyed and observed. The machine contains two separate feeding units and has the scope of dividing the batch into two parts, with 220 kg each. This study will enable the industry to reduce loss of reprocess and rejection of fabric. The study was identified that precision setup of cycle time, run-time, dosing time and temperature gradient can improve meter-to-meter variation from 66%- 86%; the study considers the factors namely water hardness, dyes combination and dyes leveling properties were optimum. In this study it was found that a satisfactory improvement in level dyeing of 100% cotton knit fabric with reactive dye could be ensured without additional chemicals or operational costs.Download
