mathis lab dryer -The foam generated is measured in cm, and the results are plotted in the form of a graph.
Procedure for starting the FOAMY
o Switch on FOAMY
Press “ON/OFF” button of B. Display of A flashes !
o Briefly press key "0" of A --> flashing stops --> A ready for program selection
o Program selection
Hold down key “0” of A. In display of A “00” or a figure appears above Step. Press the key “+” or “-” of A at the same time to select the program.
In the case of the antifoams it is program 01. —> enclosure 3
o Choice of liquor flow rate
Press key “Const” of B , then button “liquor flow rate control” of B. “Liquor flow rate” is activated in the display of B.
Set the desired value by pressing the key “+” or “-” of B .
In the case of the antifoams this is 1.6 lt/min.
o Preparation of program start
Press key “+” or “-” of A until the number “01” appears in the A display in the Step field.
The program is now ready to start.
o Textile material
Load the textile material loosely on the support and insert it into the cylinder of the FOAMY. Close cylinder.
o Foaming medium
Pour 1000 ml foaming medium into the foam generating cylinder. Close cylinder.
o Starting the program
Actuate the “Press” key of B. The system is pressurized. At 0.9 bar actuate the “Press” key again to stop the pressure increasing further.
o Press the "Pump" key of B. Liquor circulation starts.
Wait until the rate of liquor flow has stabilized at about 1.6 lt/min.
o Press key "S" of A .The time/temperature program starts running.
The entries and the current temperature, time and program step status now alternately appear in the A display.
o When the layer of foam in the foam generation cylinder has reached a thickness of 30 cm, meter in the required amount of antifoam via the sluice.
o Foam thickness in cm: note and record with reference to table "Foam measurement FOAMY ". --> enclosure 4
o On completion of testing, drain off liquor, remove material and clean FOAMY by a separate program.
Air tray dryer unit: should be able to investigate convection drying of solids on 4 corrosion resistant plates in a drying channel by air flow velocity via adjustable fan speed. It should have air heating with controlled heaters as well as sensors for measurement of humidity and temperature of solid samples before & after the completion of drying process. It should also be provided with digital weighing balance for measuring the overall change of weight during drying process. This unit should preferably be supplied with following specifications
Plastic Staple Machine used for tacking the garments after washing this garments will marked where the tag is attached.
The composition/wash care labels
Labels must be in white polyester satin with printed information in black.
Exception- all the garments that undergo an overdyeing process, you are allowed to use a woven label OR you will have to protect the labels with a polybag before the overdyeing process., if the label is printed.
There are three labels –
The composition label
The wash/care label
Label with the reference number+ supplier code (which shall be communicated to you by the concerned buyer at the beginning of the season
The composition label
Dimensions 12cmx3,5cm
Type of information
The composition of the garment outshell and the lining should be mentioned in the following European languages and in the following order -ENGLISH/ FRENCH/ GERMAN/ ITALIAN/ SPANISH/ PORTUGUESE/ DUTCH
The repartition in percentage must appear in the decreasing order e.g. 50% COTTON / 48% POLYESTER / 2% ELASTANE
the country of origin in the aforesaid language order.
the wash care label
Dimensions 12cmx3,5cm
wash care instructions. You must communicate to the buyer the wash a specific garment may or may not undergo, who in turn shall make the final decision depending on the saleability of the product and making sure that a particular washing instruction does not hinder the selling of the garment.
The respective size of the garment
Wash/care symbols
Be careful, you have to put the wash care symbols in the following order from this year
first letter represents the washing symbol
second letter the bleaching symbol
third letter the tumble drying symbol
fourth letter the ironing symbol
fifth letter the professional dry-cleaning symbol
sixth letter the wet-cleaning symbol
seventh letter the natural drying symbol (ISO 3758 only)
the style name and supplier code label
Dimensions 5cmx3,5cm
The style name e.g. M1GATOR J2
Colour
Size
The supplier code in 3 letters e.g. GRE
(Greenhouse exports becomes GRE)
POSITIONING OF THE WASH/CARE/COMPO/REF LABEL
All the three labels must be placed in the following order
The wash-care label on the bottom
The compo label on top of the wash care label
The style name label on top of the compo label
Hydro extractor
Hydro extractor is the m/c by which water is remove from garments . After wash we put the garments into hydro. When hydro is moving with high speed that time materials and water wants to go out side butmaterials can not out but water will go. About 70%-80% water is removed by this process.
Dryer
This dyer m/c is used for drying the garments after wash is called dryer. Dryer are basically two types.
Gas dryer : In this dryer gas is directly burned & heat is produced then applied on garments.
Steam dryer : In this dryer steam is converted to heat exchanger then the heat is applied on garments & dry.
Conclusion
Plastic Staple Machine is very essential for rmg industry
Best industrial washing machine is the most common operation during wet processing. A wet processed fabric goes several times in washing chamber. In woven fabric processing each machine having continuous washing ranges. But after few process no additional washing option for that an individual washing machine is required. After cold pad batch, peach finish fabric goes through an individual washing machine.

After chemical padding by using above CPS chemical steaming and washing is done.
Dryer of Best Industrial Washing Machine: After washing & neutralizing for drying process 2 stage vertical cylinders dryer is used. It is heated by steam. Here the temperature is around 120 – 150’C.
Dryer
Cooling Roller of Best Industrial Washing Machine:Dried fabric is passed over two cooling roller. It is cooled by cold water passing through roller by contact of which fabric become cool.
Cooling Roller
Batching: Finally the fabric is rolled in batcher. Then it is transferred to finishing section for finish process.
Conclusion
By using industrial washing machine and dryer such as Pad-dry-cure m/c, Pad steam m/c, Cold pad batch dyeing machine, Jigger m/c, Washing m/c.The entire bulk of the material is changed physically or chemically and fabrics look mono uniform colored.
