Abstract: A heating apparatus in a color test machine comprises a rotary tumbler seat, a rotating shaft for turning the rotary tumbler seat, a heater for heating the rotary tumbler seat, and tumbler recesses provided in the rotary tumbler. It is characterized in that solid micro particles are used as heat transfer media for heating and preserving the heat.

Abstract: A test tumbler in a color test machine has an outer cylinder, a cloth wound device, at least a knock rod, and an upper cap. The outer cylinder has a hollow chamber, and an open end and a closed end. The cloth wound device has a piercing circumference, and a sample cloth is wound on the outer surface or on the inner surface. At least a knock rod is received in the cloth wound device. The upper cap is detachably blocking the open end of the outer cylinder. Once the cloth wound device with the wound cloth and the knock rod is placed in the outer cylinder together with a dyestuff, the test tumbler is put in a receiving recess of the color test machine after the upper cap blocking the open end of the outer cylinder. The test tumbler can be rotated as soon as the color test machine starts to run such that the knock rod can strike the cloth wound device to perform a dyeing operation on the wound cloth evenly.

Abstract: A beaker for a sample dyeing machine comprises a hollow beaker body and a longitudinal sliding cylinder with flanges on both its ends. The outer wall of the cylinder is uniformly perforated for wrapping of a sample yarn or cloth to be dyed. A plurality of grooves is separately formed on the periphery of either one of the flanges to guide the flow of a dye solution. An annular passage is formed in the interior of the cylinder from one end to the other for allowing a dye solution to flow between the passage and the perforated wall of the cylinder. The beaker thus constructed can dye a sample uniformly and efficiently due to sufficient contact between a sample and a dye solution. The beaker also comprises a hollow tube outside the beaker body for one-way flow of a dye solution, and/or a dispensing device screwed on the top thereof for liquid addition to the beaker. A sample dyeing machine comprises a plurality of the beakers in a fixed rack.
