Nippon Kayaku (Thailand) CO., LTD.
Technical Service Center「KP 5L-SF 200 and KM 6L-SF technical information」
Nippon Kayaku’s high light fastness and sublimation fastness disperse dyes, KP 5L-SF 200 and KM 6L-SF series,
were developed in accordance with the higher requirements of light fastness in home and outdoor textiles.
For a more general introduction of the series, please see [Disperse dyes] KP 5L-SF 200 and KM 6L-SF.
This document will compare the KP 5L-SF 200 and KM 6L-SF series with other disperse dyes in-depth, presenting
the technical data for the light fastness, pH dependency, and step-dyeing of both series.
・ Nippon Kayaku’s KP 5L-SF 200 and KM 6L-SF were developed as a cheaper alternative to disperse dyes
for automobiles that can satisfy the increasing light fastness requirements in textiles, especially those usedin outdoor applications, where the light fastness of general disperse dyes are insufficient.
・ Although the disperse dyes generally used in automobile textiles can meet these higher light fastness
requirements, the processing costs may be unfeasible for many dyeing factories, and the light fastness
obtained may be too excessive for the requirements.

In general, from the data above, we can conclude as follows:
・ For general uses in disperse dyeing where there are no issues in light fastness, the introduced series may
not be required.
・ However, in some cases, should the light fastness requirements of the apparel company become stricter, orin cases where the fiber becomes finer, the dyes which is usually used may not be able to meet these more
stringent requirements. In cases like these, we would truly appreciate the opportunity to introduce our KP
5L-SF 200 and KM 6L-SF series.
・ The trichromatic colors of KP 5L-SF 200 and KM 6L-SF are not suitable for alkaline dyeing, but display
relatively good stability under changes from acidic to neutral pH, allowing for ease of use. Although
reproducibility will also depend on other factors such as mixing ratio of different deniers or PET/CDP
mixtures, at least we believe that poor reproducibility due to pH is unlikely to occur.
・ The KP 5L-SF 200 and KM 6L-SF trichromatic colors are developed to provide relatively uniform stepdyeing.
・ The effect of matched trichromatic colors in step dyeing on reproducibility may be small as most of thedisperse dyes, aside from the case of extremely deep shades, will be absorbed almost completely. However,when creating or adjusting a dyeing temperature program for the purpose of preventing unlevel dyeing, itshould be easier to create and adjust a program if the step-dyeing are aligned.
