WASHING FABRIC

Self-cleaning filters




Our filters are applicable to machines for washing fabrics, handmade, not processed, assembled "a remnant" of various colors and texture, with a prevalence of silk and cotton.

The filters were also applied in some case, to washing machine of fabrics treated dressings. Mostly cotton.
In all these cases the water must be recycled: it contains wire in large quantities, several inches long . Elsewhere there are cotton fibers and glue.

Such pollutants cannot be treated with the cartridge bar, but only with cartridges hole combined with a unique scraper system. Preferably, where there are long fibers, it is best cleaned with scraper tangent blade.

In cases where our filters are not used usually operate self-cleaning filters with clean operating in counter-flow, low pressure. They have the disadvantage of being low-pressure (often only a few feet of head) and then no not allow the process with a pump to recycle water.

They are also bulky and low flow rate.


Self-cleaning filters


Recycle


Introduction of a self-cleaning filter before recycling a liquid (water wash) from tissue treatment. The fluid is clean even after spending several meters of fabric and suitable to be reused for several cycles of washing.

Self-cleaning filters are also used to recycle the water of cooling tank cylinder tensioning for the fabric.

The water goes in a heat exchanger before returning to the cylinder in contact with the tissue.


Bleaching and mercerized fabrics


This filter is on line (closed) of treatment with soda water (not o water of wash).

There is a strong presence of caustic soda in the water, normally kept at about 60 ° c. Including particles: generally dusty, but lint and become difficult to manage if the wash steps cleaned tissue.

The solution now well established through many years of experience is the use of special filters specifically designed in collaboration with leading textile machinery manufacturers (Italians and foreigners).

The filter is normally subjected to high loads filtration cause in that area of plant should not be very dirty, even if they have found numerous cases where there are many fibrils (mainly in textile factories in the East).

Devorè working


The fabric "devoré" releases in the water about 80% of its volume: the amount of residue is so impressive. In fact, the tissue is burned by acid, which follows a mold (see drawing): the water jet removes all burnt: 80% of the weight of the fabric is removed by washing.

In this application, the cleaning of the filter must operate continuously, while the discharge must be timed with a drain every 30 seconds-1 minute. The application was made with a tangent blade.
This system was originally given little problems of premature wear of scrapers cleaning, now outdated due to new materials and appropriate structural adjustments in the areas of greater mechanical stress.
The product is to divide is not with fiber but with dust so there are cases in which the solution proved ideal was to use a wire brush steel wire


OTHER ANWENDUNGEN


Finishing


Filter to protect the nozzles finishing: water recycle treatment


FULL CONE NOZZLE


Nozzles used in textile sector for washing like maintenance on machine often fed up with filtered water with self cleaning filters or static positioned to protect the ramp open for the overflowing water to wash the fabric.


SELF-CLEANING NOZZLE


The nozzles are used to spray water and detergents to wash the fabric in a textile machine.

The self-cleaning (made with a simple reduction of the supply pressure that allow the automatic opening of the passages inside the nozzle) and ease of installation are the advantages of this application.


HYDRAULIC ATOMIZERS


The nozzles are used (complete with small filters) in air conditioning industries. 


FLAT JET NOZZLES


Washing

The nozzles are installed on a machine that passes the raw fabric through several rollers to stretch the fabric.
Operations made by flat jet nozzles are, first a good rinsing, then washing, bleaching, and finally another rinse before entering the drying zone.

Another use of flat jet nozzles for cleaning fabric in bleaching machine (fabric finishing). After being subjected to the treatment of bleaching to whiten the fabric and washing with surfactants to clean it, the same is passed under jets of water for rinsing. Nozzles must be in stainless steel 316 because they are used in a part of the machine where there is still the presence of bleaching substances.

They also several nozzles “on drawing” designed to be used for washing fabrics woven in the printing of fabrics.

There are usually very long baths (20 mt) with a width of 6 / 7 meters. The fabric passes under reduced dimensions of these nozzles before going to the molding. These facilities are at drawing because they need compact size for limited space between the tube and fabric.

Finishes


Deflected nozzles are often used in high-impact for washing machine finishing.

Industrial laundries


Are often used nozzles born specifically for this sector.
Completely devoid of sharp, finely finished to avoid damaging fabrics during the laundering process that can come into contact with the washing system.
They are usually high flow and high impact.


Special

For the resolution of major problems of excessive drying of the yarn or fabric that can cause static electricity that can cause breakage, with large losses of manufacturing .hydraulic atomizers are used in the series, Mx or Mz at low-flow micro-spray that have solved this problem completely . In special cases (due to weather conditions or areas critical machine difficult to serve with a series of fixed sprayers) are often used mobile systems like DRY MIST EUSPRAY® that you can look in the  “NEWS” to the Home page of our web site.
