涤纶超细纤维染色深度与色度关系研究

A Study of Relationship betwean Depth and Colrimetry of PET Microfibre Dyeing

以涤纶超细纤维和普通长丝为对象,比较不同o.w.f染色各项色度学指标和R_λ—λ曲线,揭示了o.w.f和△R_(?)、△(K/S)_(?)、△C等的关系.

Three representative disperse dyes are selected to dye two gropus FDY and DTY of PET microfibres and ordinary fibres yarns. The Rmin,(K/S)max,C* and other chromatic values and the Rλ-λ curves between the two dyed yarns at different o. w. f conditions are compared. The relationship betwenn o. w. f and ΔRmin,Δ(K/S)max C are revealed.
