ABSTRACT

QS-process: Squeezing/suction technique in accordance with the principle of Capillary dehydration developed by Pfersee. This is one of the low wet pick-up techniques; liquor reduction in the goods through capillary liquor exchange. Material which has been conventionally padded and squeezed in the first padder nip to the usual liquor absorption is brought together with the same, but dry fabric, and pressed against it in the 2nd nip. This results in removal of the excess liquor (adhering liquor), leading to a reduction in the liquor uptake by a further 1540%. Liquor treatment squeezing/suction methods on cotton approximately 40%. Advantages Low wet pick-up. Principally used in resin finishing.
