Purpose of processing
This process has the purpose of fulling and washing in rope, in a single machine - called purgofola -
several pieces (from 4 to 8), inserted on 2 or 4 fulling groups. The basic concepts of the two processes are the same
dealt with in the sheets of the two processes (see: fulling and washing).
The whole purge machine (see figures A and B) is made of stainless steel and is automated
to ensure greater productivity, increasing cost-effectiveness and cleanliness of processes.
To treat fabrics in a different way that require different fulling percentages for each case
fulling has independent controls, with an automated management of the whole process.
By excluding the pressure of the power strip, only the purge operation is obtained.
The program overview allows constant control and optimal treatment of the pieces being processed.
The person in charge of processing must adopt a behavior similar to that indicated for both the process
for fulling and for rope washing.
The Fast Purge
Processing technology
The quick purge (see Figures C and D) is a wash similar to the rope wash but performed
with measures that increase the working speed and avoid the formation of dead folds.
It is suitable for both carded and combed fabrics.
To achieve even a slight feathering and a fuller hand of the fabric, this process involves
the flapping of the pieces on a special plate placed inside the rear wall
of the tank (see figure C, point 1).
The elements that differentiate this process from a normal rope wash are:
the speed of work;
the metal plate for shaking the pieces;
the different systems of dragging the piece, such as conveyor belts instead of cylinders
squeezers, for the treatment of different types and qualities of fabrics.
Washing: Generalities
Washing and desizing, which have the purpose of removing all impurities from the fabric (sizes,
textile oils or dirt, also resulting from previous processing), can be performed in
three ways:
to. rope washing (for heavy fabrics, mainly carded);
b. wide washing (for light, delicate, combed fabrics, etc.);
c. continuous washing (wide for large productions).
However, the washing process consists of four successive phases:
1. Soaking
The fabric is impregnated with water and a mechanical rubbing action eliminates the substances
insoluble substances, such as earth, powder and unfixed dyes, etc.
2. Pre-wash
Cold wash, light and fast, which eliminates excesses of color and dirt, which could
fix on the piece in the subsequent degreasing phase.
3. Degreasing
A water bath containing soaps, detergents and auxiliary products, in which the
oily substances used in spinning and any sizes, oily stains, etc.
The temperature of the bath is fundamental, which varies in relation to impurities and components to be eliminated
(from 20 ° C to 60 ° C).
4. Rinsing
With an abundance of water, the emulsion with all the substances to be removed is removed.
