Jeans bleaching – advantages and risks of different bleaching processes (2/3)

In the first part of the jeans bleaching report a general overview was given on the sequence of wet garment processing, and in particular, on the special requirements of the denim bleaching process.

In this part an overview is given on the different bleaching processes, their benefits and features, but also the problems of the various treatments. Most bleaching processes are made on open-pocket washing machines or barrel machines (sometimes in Asia), in which many denim products can be treated together. The difference between these machine types is the diameter of the drum and the speed of rotation. The recipes and running times in this report are based on recipes for open-pocket machines. But there are also some mechanical and technical treatments, which are carried out for each single garment.
