Crock meter –manual Colour Fastness of dyed or printed fabrics against perspiration is determined by exposing the fabric sample to the action of both alkaline and acidic reagents while in contact with undyed adjacent fabrics is placed between plastic plates under a fixed load inside an oven maintained at 370 centigrade. The apparatus used for this test is called the Perspirometer. consists of a number of acrylic plates and which can be kept in suitable loading frame. The loading frame consists of two steel plates between which the acrylic plates placed. The test specimen are stitched between suitable white cloth pieces and dipped in either alkaline or acidic test solutions. The composite sample is placed in between any two acrylic plates. A number of test specimens can be loaded simultaneously between different sets of acrylic plates by stacking them one above the other. Loading is done by keeping a standard dead weight on top of the upper plate assembly, which consists of two parallel plates separated by suitable compensating springs. The guide rod attached to top plate of this assembly is locked while under load and the load removed. The springs compensate for subsequent variations in load due to variation in thickness of the test specimens on drying. The test is continued for the required time under the specified condition of temperature. After this the samples are removed from the frame and dried. The degree of staining of the while pieces of cloths and change in colour of the test specimens are evaluated using Grey Scales and compared against standard rating cards. All the components are made of stainless steel and are finished in black stoving enamel paint to give them a corrosion resistant finish. Diameter of the Finger 16 mm for Textiles / 25 mm for floor covering. Load on the finger 900 g Length of travel of the finger 100 + 3 mm Size of the test specimen 200 x 50 mm RELATED STANDARDS : IS 766 - 1988 Method of Determination of colour fastness of textile materials to rubbing.

Rotawash Washing Fastness Tester is used for determining colour fastness of textile materials to washings. This is attained by mechanically agitating a specimen of textile in contact with pieces of specified adjacent fabrics in a soap – soda solution. Before being rinsing and dried. The change in colour of specimen and stains of the adjacent fabrics are assessed with standard Grey Scale. WASHING FASTNESS TESTER’ consists of a thermostatically controlled, electrically heated water bath made of Stainless Steel. The bath is heated by means of immersion heaters and its temperature controlled by a capillary type thermostat. The temperature of water inside the bath is displayed on a digital temperature indicator. The bath has a double walled hinged lid made of stainless steel sheets. The jars in which the test solution and the test specimens are kept during the test are made from stainless steel and are provided with rubber scales for water tight closing. They are held in a cast stainless steel rotor assembly mounted on a stainless steel shaft at the center of the bath and rotating about a horizontal axis with the help of a geared Motor. A clockwork timer is provided to stop the motor after a pre-determined time. The apparatus is fabricated on a sturdy angle iron frame and is completely enclosed on all four sides with mild steel sheet duly enameled in metallic green paint. The top of the apparatus is covered with stainless steel sheet. One hundred stainless steel balls of 6 mm diameter are supplied with the apparatus as standard accessory for providing beating action during the washing operation. Extra stainless steel balls and standard Grey Scales are available as optional accessory. TECHNICAL DATA : Number of Jars Eight Volume of each Jar 550 cc (Approx) Distance of base jars from the axis of rotation 50 mm Speed of rotation 40 to 45 rpm. Temperature of Water Bath Ambient of 980 C Motor ¼ HP 230 V AC.
