The conditions in batchwise exhaust treatment on a winch beck are simulated. foam test procedure is generated by beating the test solution in a stationary cylinder with a perforated disk attached to a stem. Volume and stability of the foam are determined by measuring the amount immediately after beating and after prolonged standing, and compared with those of known products.

Test solution The product to be tested is dissolved in de-ionized water and in water of 10° dH (12.5° Clark). A 2 g/l solution is generally used but a higher or lower concentration can be chosen, depending on the foaming properties of the product.
Procedure The test is usually carried out at a temperature of 25°C + 2°C. In exceptional cases it can also be performed at higher temperatures.
200 ml test solution is poured into the
measuring cylinder, care being taken to avoid foaming. The cylinder contents
are foamed by moving the plunger up and down 60 times at an even rate for 1
min. At each stroke the perforated plate is raised from the bottom to about the
1000-ml mark on the cylinder. After 1 min the plunger is taken out.
Assessment The amount of foam in ml between the top of the liquid column and the upper foam surface is measured immediately, after 1 min, after 5 min and after 10 min. foam test procedure
General
Conventional methods used to determine foaming
properties are based primarily on ascertaining the rate of collapse of foam at
a given temperature. (–> FHP 00.10,
FHP 00.11, FHP 00.12, FHP 00.14).
By and large these provide useful pointers to
the foam-forming or antifoam properties of
surfactants.
Yet they fail to yield practically relevant
information regarding antifoams by making too little allowance for a number
of factors with a major impact in
application, e.g.
– behaviour
at temperatures > 100°C and under
pressure
– behaviour
at a realistic cycle of temperatures
– continuous
foam generation in circulating liquor systems
– influence
of textile materials
– influence
of processing aids present on the textile
– uptake
or filtering out of antifoam components onto the textile
etc.
The FOAMY HT foam tester, produced in a joint project with ZELTEX, is a further development of the ” Berendt System”. The
new instrument, which consists of a ZELTEX
COLORSTAR CS 2 and the ZELTEX
FOAMY foam tester, enables
foaming properties to be studied under closely simulated mill conditions. The FOAMY
operates on the circulation principle. The liquor is pumped through the
textile material and through a spray nozzle with defined holes onto the liquor
surface, generating foam. The antifoam can be metered in via a sluice. Temperature and time conditions are
controlled by the integrated PC 1000
microcomputer. The rate of liquor flow is controlled by a microcomputer
integrated in the CS2.

Working procedure
1.1
Introduction The FOAMY is used in particular to test antifoams such as o Albegal FFA o Albegal FFD o Albatex FFO o Albatex FFC o Cibaflow CIR o Cibaflow JET o corresponding research formulations o and competition products. The procedure is the same for all products: – charge with textile material and a foaming medium – generate foam by circulating liquor through the spray nozzle – add antifoam – start the time/temperature program – note and record the thickness of the foam layer
See enclosures 1 and 5 for a description and technical data of the COLORSTAR CS and the FOAMY respectively. The description of the PC 1000 is given in enclosure 2.

Request for Certification
The Certification Recommendation will be submitted with all relevant materials to the next scheduled Board of Directors Certification Review Meeting for certification. Upon certification, the facility will receive immediate written notification of certification, valid for a one-year period. To maintain certification, the production facility will receive unscheduled visits by accredited Independent Monitors during the period of certification. The number and frequency of the follow-up evaluations will be determined by risk-based program criteria and the conduct of the facility. Risk- based criteria will be weighted to how a factory consistently satisfies compliance requirements as evaluated by an Independent Monitor.
Why Garments wash?
Washing is must in textile technology for many purposes. Like-
Washing process of garments is done to create wash look appearance. After wash garments create a new looks which seems the touch of fashion.
By the washing technology, Faded/old look, color or tinted affect is created in the garments, which also seems the best touch of garments.
Washing technology creates new fashions such as deep dye, tie-dye, tagging, grinding, destroy and many others.
It removes many hazardous impurities like grease, wax, enzyme, alkali, bleaching agent, oxidizing agent etc from garments to prevent producing hydro-cellulose and oxi-cellulose. If the impurities remain in the garments, it could be harmful for our health.
It also reduces the size materials as a result the garments become size free and make it soft hand feel.
To attract the customers/buyers by different types of fashionable washed tems and market development.
Due to washing, shrinkage occurs in the garments. There is possibility of further shrinkage.
Any dirt, spot or germ if added in the garments during manufacture, is also removed during washing.
During garments cutting, 15% garments is cut out as wastages, if this 15% garments is cut out as grey garments, the wastage cost will be saved.
Conclusion
All Mini Extruder Screen products manufacturing facilities in the United States and off-shore, direct sewn product production facilities, independent sewn products manufacturing suppliers, licensees, and subcontractors that employ people in the manufacture of sewn products in a production facility.
