The Effects of Antimigrant on Dye Migration During Drying in Continuous Dyeing of P/C Blended Fabrics

폴리에스테르/면 혼방직물의 연속 염색시 건조 과정에서의 Antimigrant의 작용에 관한 연구

The effects of antimigrant on dye migration during drying in continuous dyeing of Polyester/Cotton blended fabrics were studied. C.I. Disperse blue 125 and Na-alginate were used as dyestuff and antimigrant, respetively. In order to investigate the effects, critical moisture content and wicking property were measured and the capillary radius through the water concentration gradient of fabrics was also determined. The results showed that dye migration during drying was affected by viscosity of dye liquor and the increase of the Na-alginate concentration resulted in the decrease of radius of the most frequently occurring capillaries and max. capacity of the continuous capillaries.
