LANASET - Dyes for Wool
The universal dyeing system
Promotion focus:
Main recommendation for dyeing wool in the segments : - loose stock - slubbing - yarn - fiber blends - Dyeing system with highly compatible dyes and ALBEGAL SET as dyeing auxiliary - fiber protective method (dyeing at iso-electric point (pH 4.5) - fast, easy and robust dyeing method - high fastness level ( wet- and light-fastness )

LANASET dyeing system - The dyes

simple dyeing procedure almost identical dyeing behavior very similar exhaustion uniform shade build-up in combinations very good fiber levelness almost identical migration, i.e.. 20% up to 97% exhaustion of dye baths balanced processing and in-use fastness properties, exceeding minimum IWS Woolmark requirements at all shade depths ideal suitability for dyeing wool in blends with PA, S, CEL, PES and PAN
KK = relative combination parameter DK = relative diffusion parameter
Excellent compatibility warrants: •Superior levelness •Superior shade reproducibility •Superior productivity
