Dosi d’impiego
Dyeing of wool fiber and polyamide:
It is an excellent dyeing agent for polyamide fibers in the presence of 1: 2 type complex metal dyes.
The dosages vary from case to case, depending on the shade of the dyes and therefore the percentages of the dyes used: on average
they are between 2 and 3% fiber weight.
Dyeing of wool and / or polyamide with cellulosic fibers:
It is a specific reservoir for dyeing called “mezzalana” as it avoids the rise of direct dyes on the wool or polyamide fibers.
The doses of use are between 1 – 5% fiber weight. a second percentage of the colors used.
For a light color, 3% fiber weight. is usually recommended.
Post-treatment of protein and / or polyamide fibers:
BLOCKER 496 is useful for increasing the wet fastness of acid dyes made on wool or polyamide.
The dyed and rinsed material is briefly treated with 3 – 7% BLOCCANTE 496 by adjusting the pH to approx. 4.5 with acetic acid at
ordinary or lukewarm temperature for about 20 ‘.
