表观色深与纤维细度关系

Relationships Between Apparent Shade Depth and Fibre Fineness

用三种不同结构的分散染料,分别以不同owf的用量上染异形截面DTY、圆形截面FDY超细涤纶长丝和常规涤纶长丝,对其表观色深(K/S值)和积分深度Integ值与纤维细度的关系进行分析讨论.其结论为,在相同的上染率情况下,超细纤维与常规纤维的表观色深或积分深度比在数值上接近于纤维比表面的反比值或这两种纤维细度比的平方根值(d_(超细)/d(常规)),这种接近并非因表层染色(环染)引起,而系色度学原因造成.

Three representative disperse dyes are selected to dye two kinds of polyester fiber, microfiber (FDY-round section. DTY-non round section) and ordinary fiber with 1% ,2%, 4% owf. The ratio values of ( K/S )micro/(K/S )ordioary, ( K/S )max, micro/( K/S )max,ordinary and Integmicro/Integordioary are nearing the values of at the same dye-uptake.
