Poly(trimethylene terephthalate)/Cellulose 교편물의 전처리 및 염색에 관한 연구

Abstract

The effect of mercerizing, presetting and dyeing of single jersey poly(trimethylene terephthalate) (PTT)/cellulose knitted fabrics were carried out. Pre-treating, dyeing, and finishing conditions were optimized to make uniform PTT/Cellulose knitted fabrics. The optimum conditions of the PTT/Cellulose knitted fabrics for mercerization were 22.5 wt% NaOH, 20 oC and 23 m/min of tenter speed. A cold-pad-batch (CPB) dyeing method could minimize process problems of high tension and rubbing in comparison with an ordinary exhaust dyeing method. Fastness was the best when the fabric was dyed at temperature of 105 oC and for 40 min. We resolved a tailing problem of the CPB process by controlling tenter speed and temperature.
