Experiment 8 was full of information about compressor, widely used for spraying on garments during dry process .PP (Kmno4) is filled in a small cup like tool and a nozzle attached to it makes the way for compressed air to come and switching on trigger will enable the action of air coming from the cylinder. This air actually responsible for the deposition of PP solution on garments surfaces. We also knew about the functions of different parts of this machines.

Conventional method still can be found in garment industries and different methods are applicable according to the buyers preferences. These are improved machinery are being used currently but sustainable manufacturing may demand something better as it is at present.
