Nylon fibre formation and properties in relation to dyeing

A review of nylon fibre formation is presented together with a discussion of the chemical and physical properties of nylon in relation to dyeing. The range of dyes available for dyeing polyamide fibres is outlined in addition to the mechanism of dyeing nylon with acid dyes.

Why CIELAB needs to be replaced for industrial color difference calculation

The agreement between the Munsell system as represented by the Munsell Renotations and the CIELAB formula is shown to be only moderate. A new formula has been fitted to teh Munsell Renotation data that describes it much better. However, historical information indicates that there are doublts about the visual uniformity of the Munsell Reno..

An application of the Kubelka-Munck relationship to calculate the color fastness of a fabric

The fastness of a dyed fabric is currently estimated using empirical rules, and generally the same rule is used for a complete class of dyes, such as reactive dyes. Actually, by measuring the different colorimetric corrdinates of a fabric before and after the test, it is possible to calculate a fastness assessment, this measurement being ..
