BACKWASHING PLANT FOR DEYED MATERIAL

BACKWASHING PLANT

FOR DEYED MATERIAL

lisciatrice per tinto

Washes and dries wool, acrylic or polyester tops after the dyeing process

Lava e asciuga i tops di lana, o di acrilico o di poliestere, dopo il processo di tintura

THE CONTINUOUS BACKWASING PLANT PERFORMS THREE DIFFERENT OPERATIONS

Washing in order to eliminate all the dye particles unfixed on the fibres and other residues of chemicals used during the dyeing process

Even application of additives: softeners, lubricants, antistatic agents and others.

Low temperature and high speed drying in order to prevent yellowing and increase hourly plant productivity

WASHING EFFECT AND EVEN AND REGULAR PRODUCTS APPLICATION

The suction drum bowls ensure the circulation of liquids, thus allowing forced penetration of the backwashing bath into the tops. In addition, the very low sliver tension along the entire treatment keeps the fibres swollen and voluminous.

This allows the complete passage of washing substances through the slivers. The amount of circulating bath is regular and uniform for each sliver running through the the backwashing line.

IMPROVED SPINNING PERFORMANCE WITH SIGNIFICANT CV REDUCTION

IMPROVED SLIPPERINESS AND SLIDING OF THE FIBRES PAST ONE ANOTHER

MINOR AVERAGE REDUCTION OF THE FIBRES LENGTH DURING THE PLUCKING PHASE

BETTER YARN UNIFORMITY AND REGULARITY

NO GENERATION OF UNFIXED DYE DUST DURING ALL THE SPINNING PROCESS

LESS PILLING EFFECT

EMA Automazione has developed an automatic dosing system, which ensures the continuity of chemicals dosing, even with the variable working seed.

CHEMICALS DOSAGE CONTROL

EMA Automazione has developed an automatic dosing system, which ensures the continuity of chemicals dosing, even with the variable working seed. The system works according to the number of processed slivers, the weight per tops’ linear metre, the production speed and the percentage of product to be applied. Based on this data, a continuous and precise dosing of each individual product is carried out.

The pumps, which feed the chemical station, are highly precise and sensitive.

The flow meter controls also the consumption of water used for rinsing in each individual tank via the overflow drain, thus limiting waste and consumption when the machine stops.
