The Pyongyang Kim Jong Suk Textile Mill is widely known across the country as a model unit of self-development.
It is evidenced by its large-capacity and modern canvas production process.
When the textile mill was tasked with building a new canvas production process, its employees rose up to build the process which relies on domestic raw materials and equipment, rather than taking an easy way of weaving canvas with rayon yarn by using hydraulic looms like in other countries.
However, lots of problems arose in producing canvas from home-made tetron rayon by using elastic staff looms.
The textile mill resolved all the problems in collaboration with the technicians and experts of Pyongyang Han Tok Su University of Light Industry and the Pyongyang Textile Machine Factory, including the selection of two-ply weft in the elastic staff looms and the making of high-temperature and high-pressure roller dyeing machines that are capable of conducting dyeing work on the high quality level to meet the technical and economic indexes of canvas whose thickness differs from ordinary cloth.
In the course of this, it finally built the tetron rayon-based canvas production process which is equipped with elastic staff looms and high-temperature and high-pressure roller dyeing machines.
The high-temperature and high-pressure roller dyeing machine is more advantageous than the previous dyeing machine.
Operated by the PLC control system, the dyeing machine is designed to freely move an autoclave, prevent the formation of wrinkles on the canvas during the whole process of dyeing, and ensure even tension and dyeing.
It consumes one fifth less water than before and saves a great deal of electricity, and the quality of dyeing is very high.
Technicians remodelled dyeing machines into multifunctional ones so that they could be used to dye even ordinary cloth.
