A Crockmeter is used for the determination of color Fastness of textiles against rubbing under either DRY or WET condition. Crockmeter Motorised is an advanced version of the hand operated Crockmeter. These machines are operated by a gear motor in which the arm moves in an oscillating motion over the test sample.
Motorised Crockmeter consists of a rigid flat metallic platform on which the test sample can be held firmly and an abrading finger, which rubs against it under a specified load. The platform is fixed over the base of the equipment and lies in a horizontal plane. The test specimen is held firmly over an abrasive paper, which is pasted on the upper face of the platform with the help of two pins holding it at both ends.
The abrading finger has a flat circular rubbing face, which is covered with a piece of white abrading fabric during the test. The abrading fabric picks up color lost by the test sample during rubbing. It is held over the finger with the help of a spring grip. Motion to the finger is given through a reciprocating arm, which runs on two wheels to minimize friction and to apply a uniform load on the finger. The arm is moved by crank and connecting link.
The equipment is finished in dark grey metallic painting and bright chrome plating to give it a corrosion resistant finish.
The color fastness has been a big problem in textile industries but thanks to the presto's Corckmeter, now we can easily test the color fastness of our products and protect them from color bleeding. A very efficient and simple to operate instrument.
