WASHINGObjective of washing- To remove the soiling Irreversibly transfer to the washing solutionBring the unfixed residual dye in the core of the fibres to the fabric surface and to remove itWashing out of salts, residual chemicals and pre-emulsified oils.
“Washing is the key to each textile process”
FACTORS AFFECTING WASHING
Fabric type Production speed Liquor exchange rate
THE WASHING MACHINE LINE NEED
High Liquor TurbulenceIntensive Liquor Cross Flow Through the FabricFast Liquor Exchange in the FibreEffective Removal of Hardly Soluble ImpuritiesWashing Result Independent of fabric Speed

FABRIC WASHING MACHINES
CONTINUOUS MULTI CHAMBER OPEN WIDTH WASHING MACHINE
System consists of specially shaped impellers in every drum in which water jets uniformly hit the full fabric width
High performance on the upper and back side of fabric
Partitions for counter current for bottom fabric guiding roller to attain optimum use of washing liquor.
Tension-less washing of fabrics
• 12-meter. 16-meter compartments for washing.
• 21-meter compartments for soaping
• Relaxer compartment for swelling for thickener.
• There is optimal balance between time and squeezing power.
• Each washing compartment equipped with its own re-circulation pump, filtering device, overflow, drain and heating arrangement.
CONTINUOUS MULTI CHAMBER ROPE WASHING MACHINE
• Long dwell times, controlled temperature and variable liquor flow to suit individual requirement add up to high washing efficiency.
• Step-less fabric-loading controller, in conjunction with the individual drives for each section, ensures an optimum cloth run and there is no danger of the fabric storage compartments running empty or being overloaded.
CONT.…
• The machine can be operated with or without squeezing rollers
• The large Plexiglas door permits ready surveillance of the instruments. At the same time door provides protection from outside influence
REACTA WASHING STEAMER - COMBINED WASHING AND STEAMING UNIT
CONT.…Advantages• Minimal fresh water consumption leads to saving in water, effluent and energy costs
• Computer controlled tension rolls endures a crease-free fabric run
• No steam escapes from the steamtight EXTRACTA washing compartments even at high temperature
• No rubber coated press rolls
• Only single drives applied
• Controlled reproducible results

High-efficiency washing compartments EA with intermediate squeezer
High-efficiency washing compartments EA C without intermediate squeezer
FORTRACTAHigh-performance washer for surface contamination
• The cloth web is led upwards in two ducts.
• The wash liquor flows down by gravity similar
to a waterfall. A strong washing action is
obtained by this counter flow principle
• Liquor separation is effected by stripper rolls
and flat jet nozzles at the exit from the FORTRACTA
Compartment.
The short distances between rollers and the
large roll diameters assure creaseless cloth running.
Fortracta Prewasher
INJECTASignificantly lower water and steam consumption.
The washing effect of a single INJECTA compares to that of a multi-chamber high-
performance full-width washing machine.
Continuous desizing of water-insoluble starch sizes.

INJECTA
CONT.….A very natural washing process. The fabric is led through a shaft divided into two casings. Here it is subjected to high turbulence and temperatures of over 100°C. According to requirements, steam and/or water are applied on both sides. The cloth undergoes this washing process over the whole length of the casings. The substances to be washed out are dissolved in seconds. The dwelling time in heavily dirtied washing liquor is only a few seconds. Cleanly and gently desized.
TRIKOFLEX
CONT.…..
Box design with excellent torsion and floor stabilityNo transmission drives nor friction clutches; only single motor drives Separate intermediate squeezerConnectable with EXTRACTA compartmentsExcellent accessibility to the squeezers and compartments for cleaning/ maintenanceThe entire machine is steam tight.
CONT.….Optimum shrinking results ensured by single
motor drivesTwo side washing, specially important for
dense fabricLarge guide roll diameter and proper spacing
ensure crease-free operation
Liquor separation due to two circulating systems
Counter-flow by gravity possible over the whole washing range
Spray pipes adjustable from the outside
