LIGHT REFLECTION OF POLYESTER FIBRES WITH DIFFERENT FINENESS AFTER THERMOSOLATION

摘要

In the work is studied the total shade of polyester fibres after thermosolation. Experiments was targeted on quantification of temperature effect, time of thermosolation, quantity of dye in fibres and on intensity of resulting dye shade for three monitored disperse dyes. Comparison was realized on fibres of different fineness.rnObjectives was find out, how influence temperature and time of thermosolation the intensity of resulting coloured shade of polyethylene terephthalate fibres at three monitored disperse dyes. Comparison was provided at several different temperatures and times. Next concern was finding whether originate colour difference on polyester of different fineness at the same concentration of dye and uniform parameters of dyeing. Experimentally were evaluated the influence of secondary diffusion of disperse dye into fibres and changes of colour intensity.
