The unique apparatus is used for determination of colour fastness of all textile materials irrespective of there composition & their form (yaru fibre etc.) to the action of soap & sodium carbonate solution at 60 degree C .The principle of this is that a specimen of textile in contact with the pieces of specified adjacent fabric is mechanically agitated in a soap soda solution rinsed & dried & the hang in colour of the specimen & the stirring adjacent fabrics are assessed with standard grey scales. The apparatus consist of a Argon weld Stainless Steel water bath containing a rotor with which glass container flask of 500ml.capacity are rotated at a speed of 40+_2 rev/min &thermostatically controlled electrical heating device to heat the water bath so as to maintain the temperature of test solution in container at 60+_2 degree C.A mechanical timer of 30 minutes is fitted for time duration of test .A soap soda solution is to be poured in flask after the temp maintain to 60 degree C The given specimen is dropped in glass flask & rotoris rotated at a 40rpm fixed for 30mints.The results are to be obtained & tested as per specification. Digital temperature controller can be given as option.
