The Sinuiju Textile Mill in North Phyongan Province is now achieving good successes in recycling.
It was early last year when the mill buckled down to reprocessing in earnest.
“At that time, we had plenty of raw materials to ensure current production. But we attached importance to the application of advanced production methods in line with the global trend of development,” said chief engineer Ryang Chol Ung.
The factory formed a technical innovation team for establishing the production process of recycled materials and completed in a short time the design of the process consisting of moulding machine, injector, pulverizer and cooling device by learning good experience from advanced units and pooling the creative wisdom of the team members. Based on such preparations, it developed necessary devices.
The process gave birth to the general recycling workteam. The workteam pushed ahead with technical upgrading to relocate old carding and spinning machines and restore their original performance, while newly making a waste thread and rag opener, thus increasing productivity 2.5 times and saving much labour.
It also introduced new technologies including methods of removing impurities with liquid wastes from reed pulp and improving the quality of fibre with a pneumatic spinning machine.
As a result, it increased cloth production by using different wastes before producing tens of thousands of metres of shading cloth for 10 000 flats in Pyongyang.
“We will direct our technical forces to establishing a thread production process from old cloths, thus making recycling bring benefits to the country,” said Manager Kim Chang Sok.
