Effect of time variation on shade in terry towel dyeing

摘要

Cotton fibre is found more active in alkaline pH and so the dyeing of cellulosic fibres must be carried out with favorable condition which can be woven plain fabric or terry towel fabric. This research work includes dyeing of cotton terry towels by reactive dyes and its impact on particularly the depth of the shade, which varies according to various holding times. Dyeing of cotton terry towel samples by maintaining the same liquor ratio with the same temperatures by varying dwell time is performed. The washing and rubbing fastness test was carried out on the prepared samples for evaluating their effectiveness and uniform dyeing efficiency by obtaining colour strength. Thus the result obtained after the study is giving good colour strength and fastness property which is reducing the exhaustion timing and thus making the production process short for processing of terry towel fabric.
